Abstract: – The purpose of this paper is to investigate and analyse the perceptions of South Australian construction practitioners on drivers affecting the implementation of reverse logistics (RL). In this context, RL is defined as the process of moving goods from their typical final destination for the purpose of capturing value or ensuring proper disposal. – Semi-structured interviews were conducted with eight practitioners to collect data and the interview transcripts were analysed using the NVivo (version 10) package. Cluster analysis was used to cross-validate the findings and provide an in-depth insight into the findings. – The findings indicate that most of the drivers identified in earlier research are relevant for the construction industry. In addition, the study identified some new drivers that are categorised as “targeted demands by an exclusive clientele”. These drivers were found to be complementary to the economic, environmental and social drivers as previously conceptualised. In addition, a set of factors affecting the strength of drivers that had been overlooked in previous studies emanated from the interview analysis. These include the type of project and the attributes of clients, both of which strongly affect the drivers of RL implementation in construction. – The major limitations are the relatively small size of the s le of interviewees and having interviewees from one geographic area with specific socio-economic characteristics. – The identified drivers and the clustering of RL themes could be used by practitioners as a “road map” for the development of appropriate solutions to successfully promote RL within the construction industry. Organisational energies could thus be channelled towards the drivers that need the most improvement. – The study contributes to this research sphere by employing cluster analysis to customise and contextualise the drivers that were previously identified. The study goes beyond the extant literature by discovering the prominent effects of these drivers on the impact of targeted demands by an exclusive clientele. This could be of great value in terms of creating avenues for future investigations on the topic.

Abstract: The purpose of this paper is to explore sourcing strategies for facilities management services using core-competency theory of outsourcing. The aim is to develop a screening framework for deciding the suitability of outsourcing versus in-house delivery for these services based on three levels of managerial functions prevalent in a typical commercial organization. A questionnaire survey was administered for facilities managers in Sri Lanka to investigate the relative importance of these managerial functions for facilities management services and obtain their opinions on the best delivery mode. The managerial functions were derived from a literature review and verified using three semi-structured interviews prior to the questionnaire survey design. The findings showed that facilities management services that are aligned to strategic functions are suitable for in-house delivery, while those that are aligned to tactical and operational functions for outsourcing. Further studies should be conducted and extended to other types of organizations beyond commercial ones. Secondly, the quantitative study employed a smaller s le ( n = 40), and the survey items were based on the review of literature which was verified using a very small number of interviews ( n = 3). The proposed framework can be utilized when choosing the best facilities management approach for commercial organizations in developing countries such as Sri Lanka. This study contributes to the body of knowledge on the subject of facilities management by exploring the context in Sri Lankan which has not previously been done.

Abstract: The recent decade has witnessed significant demolition waste (DW) due to rapid urbanisation in many economies. Transforming from the traditional linear supply chains into a circular arrangement while thinking from ‘grave-to-cradle’ is a value-adding approach to managing DW effectively. Consequently, the concept of ‘reverse logistics supply chains (RLSC)’ has captured the attention of the construction industry. However, the poor quality of re-processed products has hindered the successful adoption of RLSC in the construction industry. Therefore, this study examines aspects of the quality assurance system needed for RLSC to manage DW effectively and efficiently. The study used a qualitative approach, including 20 semi-structured interviews with internal stakeholders of the RLSC of DW. The study empirically confirmed that the RLSC of DW should embrace an integrated system for QA, including four aspects: process, people, policy, and technology. Under process for QA, standard practices are to be undertaken separately during building dismantling and off-site waste processing stages. While people in RLSC are skilful, competent, licensed, supervised and monitored, internal and external organisational policies should also be available for QA. Besides, espousing traditional practices with innovative technologies is also imperative for QA in RLSC of DW. The study makes a significant contribution by empirically proving that an integrated system of process, people, policy and technology is needed for QA in RLSC of DW. The developed quality assurance system provides useful insights for industry practitioners about the aspects that they should embrace in enforcing QA throughout the transformation from ‘grave-to-cradle’ in the construction industry.

Abstract: Despite the envisaged benefits of BIM adoption for SMEs, BIM in SMEs has remained an underrepresented area within the available academic literature. This study proposes and draws upon a framework grounded on innovation diffusion theory (IDT) to provide an illuminating insight into the current state of BIM and the main barriers to BIM adoption within Australian SMEs. Based on analyses of 135 questionnaires completed by SMEs through partial least squares structural equation modelling (PLS-SEM) and grounded on the proposed framework, the current state of BIM adoption and barriers to BIM adoption for SMEs are discussed. The findings show that currently around 42% of Australian SMEs use BIM in Level 1 and Level 2 with only around 5% have tried Level 3. It comes to light that lack of knowledge within SMEs and across the construction supply chain is not a major barrier for Australian SMEs. In essence, the main barriers stem from the risks associated with an uncertain return on investment (ROI) for BIM as perceived by key players in SMEs. The findings also show the validity of the framework proposed for explaining BIM adoption in Australian SMEs.

Abstract: Reverse Logistics (RL) is an innovation able to bring about immense benefits for organisations in a wide range of industries through enhancing the performance of supply chain procedures. Yet, evidence demonstrates that RL has remained unexploited mainly due to the lack of knowledge about its benefits, enablers, and major aspects of its adoption and implementation. In this context, promoting the adoption and diffusion of RL into the supply chain of organisations has been recommended frequently. This chapter provides a response to such need by (1) explaining the phenomenon and dispelling the confusions surrounding the RL concept, (2) clarifying the major drivers and barriers of RL and highlighting the role it can play in enhancing the performance of conventional supply chains in addition, (3) the chapter intends to demystify the major aspects associated with implementing RL in organisations. The chapter also aims at familiarising potential readers with the major references available in the field.

Abstract: Reverse logistics in construction refers to the movement of products and materials from salvaged buildings to a new construction site. While there is a plethora of studies looking at various aspects of the reverse logistics chain, there is no systematic review of literature on this important subject as applied to the construction industry. Therefore, the objective of this study is to integrate the fragmented body of knowledge on reverse logistics in construction, with the aim of promoting the concept among industry stakeholders and the wider construction community. Through a qualitative meta-analysis, the study synthesises the findings of previous studies and presents some actions needed by industry stakeholders to promote this concept within the real-life context. First, the trend of research and terminology related with reverse logistics is introduced. Second, it unearths the main advantages and barriers of reverse logistics in construction while providing some suggestions to harness the advantages and mitigate these barriers. Finally, it provides a future research direction based on the review.

Abstract: Water conservationists have been promoting a hierarchy of measures to preserve water resources in the face of decreasing freshwater availability in the world. However, applicability of water hierarchy to the construction industry is yet to be investigated. To fill this knowledge gap, the purpose of this paper is to investigate water usage, water use efficiency, and conservation measures relevant to the construction operations. A triangulation-based mixed-methods approach was adopted for the collection and analysis of data. First, four case studies were carried out to explore the current practices and the possibilities of applying the water hierarchy to the construction operations. This was followed by a questionnaire survey, administered among construction professionals to obtain their views and to verify the findings of case studies. Strategies such as reuse and recycling were found to be less applicable and least preferred by the construction professionals compared to reduce, replace, and eliminate. Based on the research findings, three enabling measures, namely, regulation, responsibility, and reward, were found to enhance the effectiveness of these conservation strategies. Knowledge on preferences of different water conservation measures among the construction professionals and their effectiveness on construction site could help the construction companies to device strategies to mitigate water wastage and enhance water use efficiency. It could also help policy-makers to develop guidelines that would have higher probability of acceptance among construction stakeholders. The study proposes an extended water hierarchy (3R.6R) by integrating three enabling measures discussed above for the construction project sites.

Abstract: Forecasts of wastewater inflow are considered as a significant component to support the development of a real-time control (RTC) system for a wastewater pumping network and to achieve optimal operations. This paper aims to investigate patterns of the wastewater inflow behaviour and develop a seasonal autoregressive integrated moving average (SARIMA) forecasting model at low temporal resolution (hourly) for a short-term period of 7 days for a real network in South Australia, the Murray Bridge wastewater network/wastewater treatment plant (WWTP). Historical wastewater inflow data collected for a 32-month period (May 2016 to December 2018) was pre-processed (transformed into an hourly dataset) and then separated into two parts for training (80%) and testing (20%). Results reveal that there is seasonality presence in the wastewater inflow time series data, as it is heavily dependent on time of the day and day of the week. Besides, the SARIMA (1,0,3)(2,1,2) 24 was found as the best model to predict wastewater inflow and its forecasting accuracy was determined based on the evaluation criteria including the root mean square error (RMSE = 5.508), the mean absolute value percent error (MAPE = 20.78%) and the coefficient of determination ( R 2 = 0.773). From the results, this model can provide wastewater operators curial information that supports decision making more effectively for their daily tasks on operating their systems in real-time.

Abstract: The reverse logistics supply chain (RLSC) facilitates the greening of the traditional construction industry supply chain. Despite the growing interest in this approach, limited studies focus on quality assurance (QA) in RLSC, which is crucial to resolve the issue of the low quality in reprocessed products. This study aims to explore the elements which contribute to the QA of RLSC of demolition waste (DW) by conducting a systematic literature review (SLR). A total of 91 articles available in six search engines between 2000 and 2019 were exposed to descriptive and content analysis. The descriptive analysis revealed that most of the articles were experimental studies (35%) and published during the recent period of 2013–2019 (64%). Furthermore, 60% of articles were originated from developed countries while 32% originated from developing countries. The results of the content analysis established that an information-centric integrated system of process, people, policy and technology is needed for QA in RLSC, which is supported by government, regulatory bodies, industry and universities/research institutions. The study addresses the existing gap by proposing a conceptual framework, which could be considered as the foundation in enforcing QA in the RLSC of DW. Finally, the implications for research and practice and some recommendations for further research were presented. The study facilitates in paving the path to sustainable development through building the foundation to enforce QA in RSLC of DW.

Abstract: Timber waste from construction is downcycled into non-structural products, incinerated for energy generation or disposed of in landfills. Existing literature highlights that the use of reprocessed timber for structural purposes is limited. Therefore, this study aims to focus on identifying factors limiting reprocessed structural timber (RST) uptake amongst construction professionals in Australia. Current literature shows that the use of reprocessed materials (RMs) depends on user-specific personal factors and broader contextual factors. Therefore, data collection and analysis were based on the attitude-behaviour-context (ABC) theory, which affirms this relationship between personal and contextual factors in determining pro-environmental behaviours (PEBs). A qualitative research approach was adopted, considering limitations with industry expertise and the need for developing an in-depth understanding of limiting factors. Twenty semi-structured interviews were conducted amongst construction professionals experienced in using reprocessed materials, while the thematic analysis technique was used to analyse interview findings. Personal factors that limit the uptake of RST include negative cost and quality perceptions, risk appetite, the tendency to maintain the status-quo, limited decision-making capability and lack of skills and expertise, while contextual factors include higher prices, poor and uncertain quality, limitations with information availability, under-developed supply and drawbacks in the regulatory environment. The current study is amongst the first to explore the uptake of reprocessed timber for structural uses in Australia. The findings can be utilised to create a stronger demand for RST by directly addressing personal and contextual factors that constrain construction professionals from using RST.

Abstract: – The purpose of this paper is to explore the barriers preventing investment in the re-use of low-grade multi-storey building stock in order to identify attributes that determine whether an existing building is suitable for retrofitting. – Semi-structured interviews were undertaken with key industry practitioners to investigate existing practices and barriers facing low-grade building retrofits and what “ideal” multi-storey building features represent a successful investment opportunity. – The findings showed that tenant commitment is necessary before any project goes ahead and that there exist many barriers influencing the investment decision. These include: high levels of asbestos found in existing buildings changes in the National Construction Code necessitating enhanced fire safety and disability access heritage listing lack of awareness overestimation of costs involved on simple and effective energy efficiency upgrades and change in tenant demands towards modern and efficient open plan offices. Many low-grade structures are privately owned inherited assets where the owners lack the expertise and capital to undertake retrofitting effectively. – The study is focused on the Adelaide CBD in South Australia but the findings are relevant to other Australian cities. – There is room in the market for more positive and influential schemes such as the Green Building Fund that encourage more energy efficiency upgrading of these buildings. – The greater occurrence of retrofitting and re-use of older buildings, rather than demolition and rebuilding, has advantages with regard to reducing the impact of buildings on the environment and promoting sustainability. – The research has indicated certain features of older buildings which render them as suitable candidates for retrofitting and refurbishment.

Abstract: The purpose of this paper is to explore the synergies among reverse logistics supply chain (RLSC), quality management (QM) and information management (IM) concepts to enhance the effectiveness of demolition waste management (DWM) practices. A systematic literature review was conducted using 70 articles published between the years of 2006 and 2017, which were subjected to descriptive and thematic analysis. The descriptive analysis established that the RLSC concept was dealt within the majority of the publications (61 per cent), followed by concepts related to quality in RLSC (24 per cent). Only 14 per cent of the articles were based on IM concepts related to RLSC. Quality and information are interrelated in the effective implementation of RLSC. The thematic analysis demonstrated that there is a need for using quality parameters in a regulatory environment in an information-based environment. Based on the findings, future research directions were developed. The study encourages researchers to identify novel directions by combining these three concepts. The study developed a future research agenda regarding use of building information modelling (BIM) for existing buildings under novel technologies analysis of secondary market demand and supply and assessment of cost and safety management with quality in a BIM-enabled environment. The practical implications include the application of sustainable management principles based on stakeholders and the regulatory environment. Integration of the three concepts is an emerging area. This integration developed a robust approach to achieve QM in RLSC operations under a sound information flow enabling the optimisation of DWM.

Abstract: – This paper aims to present a survey of the perceptions of the barriers to implementing reverse logistics (RL) practices in South Australian (SA) construction organisations. Despite the extensive research on forward logistics and RL, there is a paucity of studies that examine the barriers to implementing RL particularly within the Australian construction industry. This study builds on the ongoing research being undertaken by the authors, entitled “Designing for reverse logistics (DfRL) within the building life cycle: practices, drivers and barriers”, which is examining the best practices and drivers that could be used as a “road map” for developing appropriate solutions for the successful implementation of RL. – Data were collected by utilising a triangulated data collection approach, a literature review and 49 questionnaires. The review of the literature identified 16 barriers to implementing RL. The quantitative survey data were subjected to descriptive and inferential statistics with correlation analysis to examine the relationships between different pairs of variables comprising RL’s critical barriers. – The following barriers were indicated as most significant: lack of incorporation of salvaged materials by designers regulation restrictions to usage of recovered materials and components potential legal liabilities higher costs and longer-time association with deconstructing buildings. The least ranked barriers were mostly drawn from the operational and industrial categories as being: organisational lack of support for deconstruction due to incompatible design lack of organisational support for deconstructing buildings due to higher health and safety risks and inadequate skills and experience for deconstruction (operational). The industrial barrier was related to “higher costs of salvaged materials in comparison to virgin products”. – First, the reported findings are focussed on one study that used questionnaire surveys within the construction industry therefore, the results may not be generalisable to other contexts. Further, studies should be conducted and extended to other industrial sectors beyond the construction industry. Second, the quantitative study ( n = 49) used a smaller s le, and the survey items were based on the review of the literature. – The identified barriers could be used as a “road map” for the development of appropriate solutions for the successful implementation of RL, and to improve the environment-related decision-making processes of contractors. – This study makes a contribution to the body of knowledge on the subject of RL within a previously unexplored SA context. In addition, the study provides some insights on the contributory effects of the barriers to the implementation of RL. It is the first work undertaken to determine the barriers to the adoption of RL within the SA construction industry.

Abstract: – Construction waste originates from various sources, generally from the inception of construction through to the completion of a building project. Previous research has shown that there is a link between the quantity of waste generated and the way labour is organized in the construction industry. However, these studies have failed to look into the sources of waste with respect to labour utilization and how it influences the generation of waste. The purpose of this paper is to investigate the influence of labour arrangements on construction waste generation, particularly the sources of waste and the attitudes of workers. – Using a combination of direct observations and source evaluations on six case study sites, the waste in direct and subcontracted labour (SL) arrangements was quantified. A questionnaire survey was administered to the workers participating in the observation study to elicit their attitudes to waste and closely linked issues. – The results show that SL produced more waste than direct labour in all three work processes considered. A lack of organizational commitment and effective strategy emerged as the main problem in waste reduction. – Subcontractors should be made responsible for their share of waste generated in a project. Main contractors should record who are “approved subcontractors” based on their performance at site which should include inter alia waste generation. The approved subcontractor method is a way of barring subcontractors from being included on future projects if they do not meet the performance standards of a main contractor. – This study shows that waste generation has a relationship to organizational commitment and strategy rather than to workers’ attitudes. In order to manage construction waste effectively, it has to be considered in the financial equation of a project, because attitudinal changes are difficult to achieve unless there is a personal financial benefit attached to it.

Abstract: The success of demolition waste reverse logistics supply chains (DWRLSCs) depend on the market uptake of reprocessed construction materials (RCMs) since resource recovery will not be viable without a well-developed consumption process. However, usage of RCMs is sparse while there is also limited focus in existing research on their market uptake. Therefore, this systematic literature review (SLR) attempts to discern trends in research on the use of RCMs and identify factors that limit their uptake. 52 articles from three databases published between 2000 and 2021 were selected for descriptive and content analyses. Descriptive analysis showed growing research interest in the area over the last 5 years. Content analysis was underpinned by Attitude-Behaviour-Context (ABC) Theory which focuses on pro-environmental consumer decisions. As predicted by the theory, a mix of personal and contextual factors affect the low uptake of RCMs. Negative attitudes, reluctance to change the status quo and limited decision-making capabilities were identified as personal factors that limit the use of RCMs. Similarly, contextual factors such as price, quality, information availability, market availability, sourcing lead times and lack of regulations, standards, and specifications inhibit the use of such materials. The review also proposes several future research directions to expand knowledge around this domain.

Abstract: The purpose of this paper is to explore the synergies between post-end-of-life of building (PEoLB) concepts and operations to achieve sustainability. A systematic literature review (SLR) was conducted using 65 articles published between 2006 and 2017, and it has been subjected to descriptive and thematic analysis. The descriptive analysis revealed that the majority of the articles were about (60 per cent) PEoLB operations, followed by (23 per cent) PEoLB concepts. Only 17 per cent of the articles have dealt with PEoLB-related strategic approaches. The thematic analysis elaborated on the literature development interrelationships between PEoLB concepts and operations impediments of introducing sustainability on these operations, remedial measures and information-based strategic approaches to achieve sustainability. Based on the findings, a conceptual framework for sustainable PEoLB operations is proposed. Furthermore, four areas of potential future research are discussed. This study presents a future research agenda including best practices to plan PEoLB operations and the development of optimisation models, risk management and information-based strategic approaches. The proposed conceptual research framework triggers and nurtures potential pathways to introduce sustainable PEoLB operations under sound information flow. This could create a basis for future empirical studies in filling the identified gaps in literature. The framework could also assist practitioners in mitigating risks associated with transportation, storing and contamination of salvaged materials through enhanced information flow. In addition, the framework provides some managerial guidance to organisations seeking ways of establishing sustainability during reverse logistics (RL) operations. This paper presents an SLR of an emerging area of research that encapsulates closed-loop supply chain through sustainable RL operations. The study highlights the interrelationships between PEoLB concepts and operations. It develops a robust approach to effectively manage the PEoLB operations underpinned by a sound information flow to facilitate sustainability.

Abstract: Construction sites constitute major sources of pollutants creating negative impacts on the environment. Sustainable construction aims at mitigating these negative externalities while promoting economic and social outcomes. Dust pollution in construction sites is an invisible hazard, which is often ignored as little more than a nuisance. Although behavioral control is a popular way of preventing dust generation, past research has paid little attention to worker behavior regarding dust mitigation. This study aims to test a model that predicts intentions to alter the conduct of workers towards dust control in construction activities. This study adopted a questionnaire survey design with construction participants in Sri Lanka, using structural equation modelling to test several hypotheses based on the Norm Activation Model. The results proved that awareness of consequences and ascription of responsibility could have a positive impact on personal norms, which in turn could influence the behavior of site employees. The study also provided new insights on employees’ awareness of dust hazards, their sense of responsibility for its control, and the importance of their company. Policymakers and practitioners are recommended to pay more attention to how to harness worker’s support to mitigate dust pollution, and construction companies should initiate educational c aigns to raise awareness about environmental impacts, to influence personal norms of the workers in building sites. This research contributes to the body of knowledge by enhancing our understanding of factors influencing employees’ dust control behavior.

Abstract: – A large number of benefits have been reported when reverse logistics (RL) is fully implemented in the construction industry. However, RL is yet to become common place in the construction sector, particularly in Australia. The particular sub-sector in which RL operates is small and weak and the remainder of the sector must embrace and accommodate it comfortably. Research is lacking on how to promoting RL in the construction industry. Very little has been done to identify the current practices that have the potential to promote RL industry-wide. The purpose of this paper is to identify the practices that work well in the sector, a strategy could be mapped out to promote RL to all stakeholders. – In order to fill the above gap, the present study used a mixed method approach to gather and evaluate current practices and their potential to promote RL in South Australia’s construction industry. Practices that were identified using a comprehensive literature review were evaluated with a questionnaire survey and series of interviews involving construction professionals. – The findings are that practices facilitating deconstruction is the most important, followed by practices facilitating the use of salvaged materials in new construction to promote RL in South Australia. Awareness of deconstruction benefits, challenges and procedures at the organisation level and facilities and services at industry level were associated with RL implementation. Availability of salvaged materials in the market was found to influence its use in new construction and as a consequence its demand. Designing for reverse logistics is another practice that could facilitate deconstruction and the onus of its promotion lies mainly with the designers. – This research was confined to one state in Australia. As such the generalisation to other states and other countries should be treated cautiously. – The findings of this study can help inform the industry and its stakeholders on areas that they need to concentrate more on to make the South Australian construction industry a fully RL integrated one. To that end the authors propose some recommendations arising from the findings reported here. – This study makes a contribution to the body of knowledge on reserve logistics within a previously unexplored South Australian context. In addition, the study provides valuable insights into the contribution of RL practices to the construction industry.

Abstract: Development of an advanced pumping control scheme is one of the useful methods that can be applied in operational optimisation of wastewater pumps. Optimisation of pumping control can benefit the utility by overall cost saving using different electricity pricing schemes from the energy market. As electricity prices can be varied based on the spot market in some countries such as Australia, the consideration of operating the pumps at the most favourable electricity price, when managed correctly, can offer remarkable savings. This paper provides understanding on the electricity spot price behaviour of South Australia in the National Electricity Market (NEM). Half-hourly electricity spot price data of over 22 years from January 1999 to June 2021 were analysed to investigate the key characteristics of spot prices, including seasonality (intraday, intraweek and seasonal price patterns), spiky behaviour and occurrences of negative prices. In addition, the possible impacts of other factors on electricity spot prices such as electricity demand and weather conditions on pump control were examined. Results indicate a strong relationship between electricity demand and spot price with the Pearson correlation coefficient up to R = 0.95, and extreme high spot prices tended to occur on scorching days with the maximum temperature above 35 °C when air-conditioner usage was high. This paper also explains the importance of electricity spot prices in the wastewater pump on/off operations and analyses opportunities for cost savings by including electricity spot price forecasts as an input of the smart controller to enhance the efficiency of the real-time pumping control.

Abstract: This article provides a picture of the latest developments in providing BIM-based tools for construction and demolition waste (CDW) management. The coverage and breadth of the literature on offering BIM-based tools and technologies for dealing with CDW throughout the whole life cycle of construction are investigated, and gaps are identified. Findings reveal that, although various BIM-based technologies are closely associated with CDW, much of the existing research on this area has focused on the design and construction phase indeed, the problem of CDW in post-construction stages has received scant attention. Besides, the now available tools and technologies are lacking in cross-phase insights into project waste aspects and are weak in theoretical rigor. This article contributes to the field by identifying the intellectual deficiencies in offering BIM-based tools and technologies when dealing with CDW. So, too, it points to major priorities for future research on the topic. For practitioners, the study provides a point of reference and raises awareness in the field about the most advanced available BIM-based technologies for dealing with CDW problems.

Abstract: The Built Operate Transfer (BOT) model has been increasingly used in transportation investments in Vietnam. However, there is still an inadequacy of risk management applications in these projects and lack of research in this area. The study aims to improve the success of projects implemented through the BOT model in Vietnam. The study followed a sequential design including interviews and a questionnaire survey to investigate the perception of stakeholders from public and private sector regarding the probability of occurrence and the severity of impact of risks in BOT transportation projects in Vietnam. Quantitative data from the survey was subjected to descriptive and inferential statistics to explore the priority of risks as well as the differences in the perception between the public and private sectors. The results showed that the top five most significant risks in BOT transportation projects in Vietnam are: (1) problems with land acquisition and compensation, (2) inappropriate location of toll booths, (3) public resistance to pay, (4) high toll rate and (5) lack of cash flow. With the exception of “lack of cash flow,” there were no statistically significant differences in the rankings of in idual risks between the public and private sector. In addition, there is a significant positive correlation in the overall rankings of all risks for both sectors. This study contributes to the body of knowledge by exploring the probability of occurrence and the severity of the impact of risks in BOT transportation projects in a developing country like Vietnam which has not been extensively explored yet. Second, it provides an insight into the perception of stakeholders from the public and private sector regarding the level of risks which is very useful for potential stakeholders in making decisions when they intend to participate in such partnerships. Third, it enables the Vietnamese government to establish suitable policies related to such projects. These contributions are very important in improving risk management in PPPs in developing countries.

Abstract: The uptake of reprocessed construction materials (RCMs) derived from demolition waste (DW) is limited, which questions the long-term sustainability of DW reverse logistics (RL). To address this gap, the current study focused on identifying informational and structural interventions to promote the uptake of RCMs among Australian construction professionals (CPs). Following a qualitative research approach with thirty-one semi-structured interviews, the study explored potential interventions that can drive broader RCM usage. The study's strength lies in the in-depth qualitative insights gathered through extensive interviews with CPs experienced in using RCMs. Sixteen informational and structural interventions to promote the uptake of RCMs were identified and mapped against the industry levels at which they should be implemented. RCM suppliers should focus on improving material quality, supply and marketing while minimising material costs. Governments should encourage using RCMs through incentivisation, supportive legislation and approval processes. The significance of awareness building and research was also recognised, which requires the collective efforts of suppliers, governmental and non-governmental bodies and educational institutes. Despite the talk around sustainable consumption, the actual walk towards this is limited from a construction perspective, as seen through the low uptake of RCMs. This study attempts to bridge this mismatch by outlining informational and structural interventions that would drive CPs to walk the talk and use RCMs for construction applications. While most studies on DW RL have focused on improving waste recovery processes, this study takes a less-trodden path and explores the potential for developing markets for RCMs.

Abstract: Risk is an unavoidable phenomenon in construction projects. Proper risk allocation in construction contracts has therefore come to assume prominence because risk identification and risk allocation have a clear bearing on risk handling decisions. The proper management of risks requires that they be identified and allocated in a well‐defined manner. This can only be achieved if contracting parties comprehend their risk responsibilities, risk event conditions, and risk handling capabilities. This research aims at identifying the risk responsibilities of contractual parties in order to improve their risk handling strategies with regard to Sri Lankan road projects. Semi‐structured interviews were used for the primary data collection. This was complemented with documentary evidence. The results show that road construction projects in Sri Lanka are exposed to many risk sources while most risks are borne by parties who were assigned with risks via contract clauses. However, parties not allocated with risks too happened to bear the consequences of such risks. Therefore, it is concluded that there is no one best way to respond to a risk and that different risk handling strategies should be adopted in order to deal effectively with risks. Santruka Rizika ‐ neišvengiamas statybu projektu reiškinys. Todel svarbus tapo tinkamas rizikos paskirstymas statybu rangos sutartyse, nes rizikos nustatymas ir rizikos paskirstymas daro akivaizdžia itaka rizikos valdymo sprendimams. Norint gerai valdyti rizika, reikia ja nustatyti ir tinkamai paskirstyti. Tai imanoma tik tuomet, jei sutarties šalys supranta savo atsakomybe už rizika, rizikos atveju salygas ir rizikos valdymo galimybes. Šiame tyrime, siekiant pagerinti sutarties šaliu rizikos valdymo strategijas, meginama nustatyti, kokia atsakomybe už rizika prisiima sutarties šalys pagal Šri Lankos keliu tiesimo projektus. Pirminiai duomenys surinkti iš pusiau struktūriniu interviu. Jie papildyti dokumentiniais irodymais. Iš rezultatu aiškeja, kad keliu tiesimo projektai Šri Lankoje imlūs daugybei rizikos šaltiniu, o daugeli rizikos rūšiu prisiima šalys, kurioms rizika priskiria sutarties nuostatos. Tačiau šalys, kurioms rizika nera priskirta, kartais irgi patiria tokios rizikos pasekmiu. Todel daroma išvada, kad nera vieno geriausio būdo reaguoti i rizika ir kad reikia taikyti ivairias rizikos valdymo strategijas, siekiant efektyviai spresti rizikos situacijas.

Abstract: Factors influencing management of construction and demolition (C& D) waste within the Iranian context have yet to be investigated. The purpose of this paper is to define and address this knowledge gap, through development of a model to map the associations among the primary factors affecting C& D waste at project, industry and national levels. A conceptual model is developed based on synthesising the findings of available studies on factors affecting C& D waste with a focus on developing countries. For collecting data, the study drew upon a questionnaire survey of 103 Iranian construction practitioners. The strength and significance of associations among these factors to modify and validate the model were assessed using the structural equation modelling-partial least squares approach. Major factors affecting C& D waste management and their level of importance were identified at project, industry and national levels. Results clearly showed that the government should review regulations pertaining to C& D waste management and make sure they are implemented properly. The “polluter pays principle” is a useful guide in devising effective policies and regulations for the Iranian context. This study contributes to the field through presenting the first major study on C& D waste management in Iran. The study provides a picture of C& D waste management status quo in Iran and encapsulates the factors affecting C& D waste management in the Iranian context at different levels within an integrated model. The findings have practical implications for policy makers and construction practitioners in Iran, similar developing economies and foreign firms planning to operate in Iran.

Abstract: While mobile Information and Communication Technologies (mobile ICTs) have been adopted by many construction organisations, research on the usage of mobile technologies in the context of construction project management has been scarce. Against this background, the purpose of this paper is to enhance the understanding of how Construction Management Professionals (CMPs) currently use mobile ICTs at work and the factors affecting their usage of mobile ICTs in the context of the Australian construction industry. In this research, the aim is addressed by a survey-based empirical research approach. A questionnaire was used to collect data about CMPs’ current mobile ICT usage and the factors affecting the usage. Then, relative importance index, factor analysis and χ 2 test were used to identify the most significant factors affecting their mobile ICT usage. This research found that user characteristics such as age or years of experience are not the major factors affecting CMPs’ mobile ICT usage. The research also found that there are several barriers hindering an effective usage of mobile ICTs, namely work-family spillover, system quality issues, inconsistency in the way of using mobile ICTs among CMPs and the lack of organisational support. The results of this research imply that to fully reap the potential benefits of mobile ICTs in construction projects, those barriers need to be addressed appropriately at the in idual, organisational and industry levels. Also, this research informs construction organisations of how mobile ICTs can be deployed and used in the most cost-effective way in their projects.

Abstract: It is well accepted that moisture ingress in concrete reduces durability and life span of water assets. Condition assessment is an important tool to inform decision for maintenance, retrofit or replacement. However, the most significant challenge is to obtain accurate condition information, particularly when the inspection points are physically difficult to access or inaccessible. Therefore, a reliable and cost-effective monitoring (sensor) system, preferably real-time with ability to streaming online, would be a useful management tool, particularly for water utilities. This paper describes an approach to develop a distributed optical fibre humidly sensor for condition assessment and environmental monitoring both inside and outside of infrastructures, such as inside the concrete and surrounding soil. A new polyelectrolyte multilayer (PEM) coating with higher sensitive was evaluated for relative humidity measurement in soil and concrete, respectively. In this study, two simulated conditions, in concrete and soil, were conducted to evaluate the sensing concept with the development of appropriate measuring methodologies including fibre installation and protection. The optical fibre sensor setup in laboratory environment showed that optical sensor can detect and indicate voltage change with the variation of moisture contents in both soil and concrete. The test results indicate a good correlation between high levels of relative humidity/moisture and transmitted optical power. A simple relative humidity (RH) calibration can be used to convert signal to RH in percentage for soil and concrete measurements and the procedure used to imbed the fibre in both s les is effective. Nevertheless, the sensor measures soil humidity (not moisture content) therefore, further investigation is required to identify the consequence for the variation of the measured parameter.

Abstract: Construction industry has adopted reverse logistics (RL) concept to manage high volumes of demolition waste (DW). However, DW RL supply chains (RLSCs) were found to be suffering from uncertainties, information deficiencies, and uncoordinated material flows. Improving supply chain integration (SCI), specifically external integration, across DW RLSCs was identified as a possible solution to overcome such problems. Despite this, studies that focus on external integration in DW RLSCs are limited. Using a systematic literature review (SLR), this study explores external integration in DW RLSCs. Sixty-six articles from three databases published between 2006 and 2020 were subjected to descriptive and content analysis. Arrangement of material, information, and financial flows across DW RLSCs, inhibitors of external integration, and potential measures for improving external integration were analyzed. Accordingly, material, information, and financial flows across DW RLSCs were mapped, and inhibitors of external integration, along with potential measures for improving external integration were identified. As the key outcome of this SLR, these findings were developed into a conceptual framework, which shows the main factors that inhibit and improve external integration in DW RLSCs. The framework will be useful in guiding further empirical research and informing industry practice. Several future research directions are also proposed to expand knowledge around the research domain.

Abstract: Construction activities generate noise that is harmful to workers and the neighbouring community. Engineering control methods are often used for its control which are expensive and limited in effectiveness. This study aims to investigate factors that affect employee behaviour and how it could be used by construction companies to manage noise pollution on sites. Norm Activation Model (NAM) is used to investigate the relationship between attitudes and behaviour of site-based employees using a questionnaire survey administered in Colombo, Sri Lanka. The responses were analysed using structural equation modelling to discern behavioural patterns and how it differs between managers and workers. The results showed that behaviour of site employees could be influenced when they are aware of the consequences of noise pollution and take responsibility for its control. Personal norm of an employee and company's environmental behaviour are found to influence the behaviour in a positive manner. Construction companies should focus more on how to harness their employee's behaviour in order to reduce noise pollution on sites. Employees should be made aware of consequences of noise pollution and feel responsible for their actions through training, awareness c aigns, signage and so on. This study contributes to the literature by building a theoretical model of employee noise control behaviour in construction organizations and empirically testing it among managers and workers. It compares the differences between these two groups which enhances one’s understanding of behavioural control methods when applied in a construction project setting. The study also evaluates the effects of company's environmental behaviour on employee behaviour.

Abstract: Every year, the construction industry produces a large volume of demolition waste (DW) recovered through reverse logistics supply chains (RLSCs). Information-centric QA plays an important role in the RLSC, providing an excellent solution for inferior-quality reprocessed products. However, information deficiency creates epistemic uncertainties that lead to information-processing needs (IPNs) for QA, for which the internal stakeholders in the RLSC should respond by undertaking appropriate information-processing mechanisms (IPMs). Given this, the current study aims to explore how internal stakeholders process information for QA in RLSC of DW through the organizational information processing theory (OIPT) perspective. The study follows a qualitative approach encompassing 30 semi-structured interviews with internal and external stakeholders in the RLSC of DW. The study found eight uncertainties that stem from the internal organizational environment and two uncertainties caused by the interactions with stakeholders in the supply chain. In addition, 15 IPMs were identified, which the demolishers and waste processors could undertake in response to the epistemic uncertainties. The study developed an information-processing management framework that would serve practitioners and academics to understand how effectively process, people, policy and technology elements contribute to responding to the epistemic uncertainties for successful QA in RLSC of DW.

Abstract: This paper aims to report the findings of a study, which analysed the strengths and limitations of two distinct concepts used for post‐disaster housing reconstruction, namely, the donor‐driven and owner‐driven approaches. Data were gathered through interviews, questionnaire survey and observations from government, non‐government organizations and the beneficiaries of owner‐driven and donor‐driven programmes in one of the affected districts. The paper reveals that beneficiary satisfaction is higher on owner‐driven approach compared to the donor‐driven approach. Further, imposition of the buffer zone, non‐availability of suitable land and capacity constraints of the construction industry are identified as critical factors affecting the success of donor‐driven housing programme. It was assumed that the quickest and most effective way to rebuild houses after a disaster is to employ the “donor‐driven” approach, where the government or an external funding agency leads the reconstruction process with the help of consultants and contractors procured for the project. Contrary to this popular view, this paper finds that there are limitations in this approach and that it may lead to housing that does not respond to needs of victims. This paper examines the strengths and weaknesses of the two strategies used in housing reconstruction and highlights the need for building regulations and technical assistance as key to overcome limitations of the owner‐driven approach.

Abstract: A green lease incorporates sustainability practices to reduce a building’s negative impact on the environment. Facilities managers play an important role in ensuring these best practices are implemented during the operational stage of a building however, green leasing is an under-researched area in the emerging field of sustainable facilities management (SFM). This paper aims to investigate the common barriers encountered in ensuring environmental performance when a green lease agreement is in operation between a landlord and tenant. This research was conducted in three stages using the principal-agent problem as the theoretical foundation for data collection. Stages 1 and 2 used semi-structured interviews to collect data with policy/corporate-level professionals, landlord and facilities management representatives who have considerable experience in green leases. Stage 3 used document reviews based on summative content analysis to further evaluate the extent of the contextual use of green leasing concepts as used within the facilities management community. The study confirmed a strong incentive gap and information asymmetry between the landlord and facilities manager, forming a typical double principal-agent problem when the split incentives between the landlord and tenants are also taken into consideration, which results in agents acting on their own self-interest rather than the interests of the principal. Goal alignment is found to be key for the successful operation and management of a building throughout its life when present, these goal conflicts can lead to disharmony between the parties to the contract. The study proposes a few practical measures to close the gaps in incentive and information asymmetry that create the principal-agent problem, while providing recommendations to the facilities management professional community. These recommendations could be included in future revisions of the SFM guidelines or code of practices used by the industry. Although this study exposed a rather neglected area of the facilities manager’s role in green leases, the findings are limited by the relatively small s le size used for the interviews. This study contributes to the SFM body of knowledge from a green lease perspective, and the theoretical framework in the double principal-agent problem introduced in the study could be used in future research endeavours.

Abstract: This paper aims to synthesise the latest literature on supply chain operations of offsite manufacturing in the construction industry to identify and evaluate the uncertainties at each stage of the offsite construction supply chain (OSC-SC) to compile contributions to knowledge and thereby determine the future research directions to improve supply chain resilience (SCR). The study was conducted as a systematic literature review. In total, 99 peer-reviewed journal papers published between 2015 and mid-2022 were shortlisted and analysed through the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The bibliometric analysis revealed that the research focusing on supply chain issues and developing best practices in offsite construction adopt case study approaches to investigate the research problems comprehensively. The content analysis revealed the lack of up-to-date knowledge in the construction workforce regarding OSC low preparedness for the changes brought by the SC uncertainties the lack of a proper procurement model for OSC lack of end-to-end visibility of the supply chain to identify uncertainties and lack of national or government standards on OSC-SC, as some of the key problems instigating the identified the uncertainties. This study clarifies the current knowledge by systematically presenting uncertainties at each stage of the OSC-SC. Moreover, it provides a framework and proposes that future research should focus specifically on in idual/team, organisational, supply chain/network and sector/national/supranational levels to improve SCR.

Abstract: IFI 16 is a member of the HIN-200 protein family named for their haemopoietic expression, interferon-inducibility and nuclear localisation. These proteins have been characterised as transcriptional regulators that modulate the cell cycle. IFI 16 is expressed in some haemopoietic lineages including CD34+ progenitor cells, mature lymphocytes and monocytes, but is absent from granulocytes, erythrocytes and megakaryocytes. We present a wider study of IFI 16 expression in normal human tissues using a monoclonal antibody specifically recognising the C-terminus of IFI 16. As expected, IFI 16 was detected in the nuclei of lymphocytes in the spleen, thymus, lymph node and palatine tonsil, but was also found in epithelial cells in these tissues. Interestingly, IFI 16 protein was also expressed in non-lymphoid tissues including trachea, gastrointestinal tract, skin and testis, but was absent from others including heart and brain. In each tissue, IFI 16 was predominantly expressed in surface epithelial cells and staining was strongest in basal epithelial layers. Therefore, IFI 16 expression is not restricted to cells of the immune system, but is also expressed in epithelial cells. In contrast to the perceived role of HIN-200 proteins as suppressors of cell growth, maximal expression of IFI 16 was in cells with high proliferative potential.

Abstract: The purpose of this paper is to investigate risk propagation and resilience in the agribusiness supply chain (ASC). The paper undertakes a systematic literature review (SLR). Overall, 94 articles from six databases published between 2000 and 2022 underwent descriptive and thematic analysis. There is a lack of research on risk propagation and resilience in the ASC for more than two decades. Accordingly, this research fills the gap in the extant literature by advancing the construct of risk propagation and resilience in the ASC and developing a framework proposing directions in risk propagation and resilience in ASC research. Firstly, only the Web of Science and Scopus databases were mostly used as primary sources while other databases were used as secondary sources to validate search results. Secondly, SLR is based on the peer-reviewed articles, books and conference papers other non-academic sources relevant to the topic were not included in this paper. The paper offers a set of constructs for understanding risk propagation and resilience in the ASC, develops a framework proposing directions in risk propagation and resilience in the ASC research and recommends three key themes for future research directions, namely, keep updated with recent constructs of risk propagation and resilience in the ASC, conduct case studies based on empirical studies to determine the current risk dependency and propagation in the ASC and conduct case studies based on empirical studies to determine resilience and sustainability in the ASC.

Abstract: The purpose of this paper is to investigate driving factors that improve the project management efficiency (PME) in centralized public procurement systems. Employees in four public-sector organizations in China were surveyed. The structural equation modeling was employed to examine the relationship amongst those variables. Organizational culture (OC) is an effective method to improve PME, and employee quality is the most critical factor of OC in this system. Job satisfaction (JS) is another significant contributor to PME and satisfaction with fairness of salary in this system being the key factor of JS. Job analysis (JA) has indirect influence on PME through JS and OC, whereas the job structure in this system is the most critical factor for JA. An operational way to improve PME is to implement it from the perspectives of employee, organization and technique. At the organizational level, it is imperative to strengthen the OC by a well-structured recruitment system and to improve PME via well-design training. At the person level, both financial (i.e. income and welfare) and career incentives (i.e. promotion opportunities and a sense of belonging) are proposed to achieve employees’ JS to improve PME. At the technique level, JA approach (i.e. job rotation) is recommended to enlarge the positive influence of OC and JS on PME. These can not only ensure the management professionalism in a centralized public procurement system but can also motivate employees and maximize PME. PME in a centralized public procurement system will be improved by addressing these key factors and their interrelationships. This provides detailed pathways for the centralized public procurement system to achieve better PME via optimal OC and JS and reasonable JA in China. In addition, the institutional and administrative traditions may vary significantly across cities, regions and countries. Therefore, such contextual differences should be taken into consideration for the improvement of PME in a centralized public procurement system.

Abstract: A water utility requires myriads of data for effective decision-making. As the sources and ranges of data are becoming increasingly complex, the use of a metadata framework can play a significant role in effective data management. Using case study method, this research analyzed data needs of a water supply system in a small town in South Australia and designed a demo portal of a metadata framework. As part of the case study, the project team undertook a broad investigative approach using focus group (interviews), observation, exploration of potential data sources, identification of knowledge leaders and information technology systems. The metadata framework comprised two separate but interconnected metadata groups, (1) metadata elements to describe the metadata source and (2) metadata elements to describe the datasets held in each data source. The metadata framework was populated to describe data sources and data held in each of the sources. The data catalogue created by this process showed that it was accomplishable and appropriate to describe data sources and datasets via a metadata framework.

Abstract: The purpose of the study presented in this paper is to determine the relationship and effect of built environment on occupants’ productivity in green-certified office buildings in Sri Lanka. Two research hypotheses were tested by approaching the survey method under the quantitative phenomenon. The questionnaire survey was conducted among randomly selected occupants in three selected green-rated office buildings in Sri Lanka. The survey data were analysed by using the Spearman correlation and ordinal logistic regression analysis techniques to model the relationship existing between the variables. The SPSS v20 software was used in data analysis. The findings confirm the relationship between built environment and occupants’ productivity. As it further proves that, there is a significant effect of built environment on occupants’ productivity in green-certified office buildings. Thus, critical built environment factors influencing occupants’ productivity and their effect were determined. The findings could be practically implied as bases to strengthen the evaluation criteria of indoor environmental quality in GREENSL ® national green-rating system. The evaluation of occupants’ productivity and the built environment factors has been at the focal point of research however, most studies have focused on single aspects of the built environment. Further, no evidences were found on “which factors” can critically influence the occupants’ productivity in green buildings. The paper, therefore, seeks to fill this gap by proving the relationship between green built environment and occupants’ productivity.

Abstract: This study aims to investigate the effect of Australian construction firms' cooperative behavior on reverse logistics outsourcing performance (RLOP). To achieve the aim, a questionnaire survey was conducted to collect data from construction firms in Australia. Following this, the study used Partial Least Squares Structural Equation Modeling (PLS-SEM) to analyze 173 responses for testing seven hypotheses that are related to the positive effects of cooperative behavior on RLOP. The results indicate that three dimensions of customer cooperative behavior (cooperation, commitment and planning) positively influence RLOP in different ways. Cooperation only directly affects RLOP while planning only has an indirect influence on RLOP. Commitment affects RLOP both directly and indirectly. This is the first study examining empirically antecedents of RLOP in the construction industry. Additionally, it reveals the mediating role of cooperation. Cooperation fully mediates the relationship between planning and RLOP, and partially mediates the relationship between commitment and RLOP.

Abstract: The public's trust in the authorities has a great impact on people's perception and cognition on development of different types of urban transport infrastructure projects (UTIPs). Given the importance of public acceptance for the efficient construction and operation of UTIPs, this study aims at investigating the personal and environmental factors that influence public acceptance behavior from the perspective of stakeholder management. Based on social cognitive theory (SCT), this study explores the multiple dimensions of social trust on public acceptance in the development of UTIPs by a comparative case study. Two types of UTIPs, a metro railway and a bridge in the Wuhan City, China, were selected as cases, with a questionnaire distributed among the public to collect their sense of trust towards the development of these projects. The data were analyzed through structural equation modeling (SEM). This study reveals that social trust positively influences public acceptance, directly or indirectly through perceived benefit and -risks and self-efficacy. However, the emphasis on social trust about competence and integrity of the authorities varies with the types of projects. Self-efficacy worked as the “mirror of trust” reflecting people's attitude towards social trust in the authorities on their ability and morality. The value of the paper lies in discussing social trust from multiple dimensions in the field of urban infrastructures, which provides new insights into specific mechanisms for shaping public acceptance in project management towards the development of UTIPs.

Abstract: The purpose of this paper is to determine the relationship between indoor environmental quality (IEQ) and occupants’ productivity improvements in green buildings in order to propose probable enhancements of national green certification criteria. Survey approach was selected under quantitative phenomenon. Hence, questionnaire survey was selected as a primary data collection technique. It was linked to semi-structured interviews to validate survey results. The survey data were analysed by using nonparametric statistical analysis techniques, such as significance testing and Spearman’s correlation. Statistical Package for the Social Science (SPSS) v.20 statistical analysis software was used in data analysis. Seven factors were identified as significant factors which showed statistically significant monotonic correlation to major IEQ dimensions. Among those, air quality and acoustical partitioning factors confirmed a statistically significant weak positive monotonic correlation, whilst system control showed strongly positive monotonic correlation to occupants’ productivity in green buildings. The findings can be practically implied as a basis to review the existing evaluation criteria of IEQ in national green certification system to propose probable enhancements. The significant IEQ factors influencing occupants’ productivity were determined as the focal point of this research. Accordingly, new provisions were proposed to enhance the national green certification criteria.

Abstract: Irrigation System Management (ISM) poses many issues in terms of social and technical aspects. These can be further elaborated as the issues toward the efficiency of infrastructure, equity of water sharing, environmental integrity and economic acceptability. Water losses and the structural changes of the system caused many issues putting the irrigation system into distress. Hence, this urges the need for sustainable ISM to improve social and technical attributes in ISM. This paper aims to apply the Socio-Technical Systems (STSs) theory for sustainable ISM. The qualitative expert opinion survey method was selected as the research strategy to approach the research aim. Sixteen industry professionals in the ISM sector were selected through the purposive s ling method to conduct semi-structured interviews to collect data in the Sri Lankan context. Code-based content analysis through a directed approach was used to analyse the data. Four main categories of strategies were emerged from the research findings as “engineering strategies”, “operational strategies”, “management strategies” and “regulatory strategies” through STS approach for sustainable ISM. The STS framework was developed by combining engineering and operational strategies into the technical subsystem and the management and regulatory strategies into the social subsystem to approach the aim of achieving contemporary system management in irrigation in a sustainable manner. The research revealed the links between the strategies emerged from various disciplines to minimise the issues in ISM from the perspectives of technical and social subsystems. The study contributes to knowledge by providing a framework for sustainable ISM by applying the socio-technical systems theory by integrating the concepts of sustainability.

Abstract: In the current practice, an essential element of safety management systems, Job Hazard Analysis (JHA), is performed manually, relying on the safety personnel’s experiential knowledge and observations. This research was conducted to create a new ontology that comprehensively represents the JHA knowledge domain, including the implicit knowledge. Specifically, 115 actual JHA documents and interviews with 18 JHA domain experts were analyzed and used as the source of knowledge for creating a new JHA knowledge base, namely the Job Hazard Analysis Knowledge Graph (JHAKG). To ensure the quality of the developed ontology, a systematic approach to ontology development called METHONTOLOGY was used in this process. The case study performed for validation purposes demonstrates that a JHAKG can operate as a knowledge base that answers queries regarding hazards, external factors, level of risks, and appropriate control measures to mitigate risks. As the JHAKG is a database of knowledge representing a large number of actual JHA cases previously developed and also implicit knowledge that has not been formalized in any explicit forms yet, the quality of JHA documents produced from queries to the database is expectedly higher than the ones produced by an in idual safety manager in terms of completeness and comprehensiveness.

Abstract: Stakeholder perspectives on supply chain risks (SCRs) play a crucial role in managing risks, achieving goals, and determining performance of an organization. Herein, the role of stakeholders and the complex interrelationships between stakeholders are important factors influencing the supply chain, and, besides, failure to manage SCRs can result in significant losses for the organization. In West Papua, study related to stakeholder perspectives on the risks in palm oil SCs is still limited. Accordingly, to fill this gap, this paper aims to identify SCRs from the perspectives of key stakeholder of the Indonesian palm oil industry in West Papua. This study employs qualitative research methods. Key risks in the palm oil supply chain (SC) were identified from semi-structured interviews with 64 key stakeholders across 25 different stakeholder groups, using NVIVO software for thematic analysis. The results show that the palm oil SC in West Papua has five tiers and five distribution channels of material, information, and financial flows. Public and private stakeholders identified in palm oil SCs play crucial roles in determining palm oil operations in West Papua. Herein, there are seven identified groups as key stakeholders with thirty-two major risks in the SC. Smallholder farmers are exposed to most of the risks, followed by plantation companies, local cooperatives, and government agencies. Interestingly, risks in palm oil SCs in West Papua are predominantly caused by conflicts of interest among multiple stakeholders.

Abstract: There has been considerable research into prediction of water mains failure, however, those models are very complex and fail to convey the message of the health status of an asset to the relevant stakeholders. The study developed a ‘pipe health scorecard’ based on historical failure data which could be used for operation, maintenance, refurbishment, or replacement decisions by a water utility. This scorecard model was developed by using 160,413 pipe-condition data sets from the South Australian Water Corporation over ten years. Measures such as the Kolmogorov–Smirnov (KS) statistic, Area Under the ROC Curve (AUC), and Population Stability Index (PSI) showed the model is strong enough to predict the health status of water mains. The study found the factors influencing water mains failure to be in the order of importance: length, material, age, location (road vs verge), diameter, and operating parameters. The development of a simple but reliable model for the assessment of the health status of water mains will have major benefits to the water utility with the ability to identify and potentially replace water pipes prior to failure. Additional benefits of flexible scheduling of maintenance and replacement programs would contribute to cost savings.

Abstract: The purpose of this paper is to explore ways to enhance water use efficiency at construction sites according to project stakeholders’ perceptions. A questionnaire survey was developed based on drivers, barriers and potential water use efficiency measures identified through a literature review. It was administered among professionals working in the construction industry who have more than ten years of work experience. The study highlighted cost of water and sources of water as main drivers that promote water use efficiency on sites. Lack of priority for water management among host of other managerial functions was identified as the main barrier. In order to conserve water, respondents favoured “soft” measures such as changes in workers’ behaviour and managerial policies and planning for water savings, as opposed to “hard” measures which were primarily technology based. The major implications of the study are related to how behaviour of the workers could be changed to accommodate water use efficiency in their everyday activities. Water saving measures such as leak detection, auditing and sub-metering were favoured by respondents referring to policies and planning, as well as implementing a water action plan when a project begins. This study makes a contribution to the body of knowledge on the subject of water sustainability at construction projects. This is an understudied area. In addition, the findings will enhance the understanding of construction companies on water use efficiency and should serve as a platform to develop improved and appropriate techniques.

Abstract: The issue of low productivity has remained a very stern and chronic problem in construction projects. Previous studies have found poor communication as one of the leading causes of low-construction productivity. Recent advances in the field of information and communication technologies (ICT) have the potential to enhance communication and access to information in construction projects. However, the implications of the use of mobile ICT on construction productivity have not been investigated in sufficient depth, especially from the perspectives of its users, i.e. construction management (CM) professionals. The paper aims to discuss these issues. A focus group session involving ten experienced CM professionals from different organisations of the South Australian construction industry was moderated by a group of four researchers to gather data on mobile ICT usage and its implications for construction productivity. Lack of training and guidelines on effective applications of these technologies to construction projects is a major bottleneck. Results indicate that despite noticeable advances in mobile ICT, differences in usage style and user attitude have limited their overall impact on productivity. This paper is based on data gathered from CM professionals working in the South Australian construction industry. The study highlights the importance of strategising the use of mobile ICT to achieve the desired productivity rates through policy, training, work-life balance, and deeper and wider understanding of these technologies. The study examines the perceptions of CM professionals on the usefulness of mobile ICT in construction projects and its implications for construction productivity.

Abstract: The construction industry consumes large amounts of natural resources, which are not properly utilised owing to the generation of waste. Construction waste has challenged the performance of the industry and its sustainable goals. The majority of the causes underlying material waste are directly or indirectly affected by the behaviour of the construction workforce. Waste occurs on site for a number of reasons, most of which can be prevented, particularly by changing the attitudes of the construction workforce. Therefore, the attitudes and perceptions of the construction workforce can influence the generation and implementation of waste management strategies. The research reported in this paper is based on a study aimed at evaluating the attitudes and perceptions of the construction workforce involved during the pre‐ and post‐contract stages towards minimising waste. A structured questionnaire survey was carried out to understand and evaluate the attitudes and perceptions of the workforce. Four types of questionnaires were prepared for project managers/site managers, supervisors, labourers, and estimators. The findings indicate the positive perceptions and attitudes of the construction workforce towards minimising waste and conserving natural resources. However, a lack of effort in practising these positive attitudes and perceptions towards waste minimisation is identified. The paper further concludes that negative attitudes towards subordinates, attitudinal differences between different working groups, and a lack of training to reinforce the importance of waste minimisation practices have obstructed proper waste management practices in the industry. The paper reveals the effect of the attitudes and perceptions of the construction workforce towards waste management applications, which would be of benefit to construction managers in designing and implementing better waste management practices.

Abstract: The reverse logistics supply chain (RLSC) for demolition waste management (DWM) is a complex process that inherits significant interdependent risks. However, studies on the RLSC have not explicitly identified the risks of its inter-relationships by disentangling their effects on operational performance. Accordingly, this paper aims to identify and assess the inter-dependencies of the risks in the RLSC to improve quality-related operational performance. A sequential exploratory mixed-method research approach, consisting of qualitative and quantitative methods, was employed. The qualitative approach involved 25 semi-structured interviews, whereas the 18 subsequent structured interviews were conducted with stakeholders in the entire RLSC as part of the quantitative method. These were used to identify the cause and effect relationships of the identified risks. The data were analysed using thematic analysis, and the Bayesian belief network (BBN) technique was used to develop a conceptual risk model. In total 20 risks in four RLSC sub-processes, namely, dismantling and on-site process, off-site resource recovery process, marketing of secondary products and residue disposal, emerged. Among cause and effect relationships of identified risk factors, inferior quality of secondary products was found to have the strongest relationship with customer satisfaction. Under-pricing of dismantling job, improper landfill operations and inadequacy of landfill levy are independent risks that initiate other risks down the supply chain. The aggregate effects of these risks affect customer dissatisfaction of the end-product, as well as health and safety risks in on-site, off-site and residue disposal. This study only identify the cause and effect relationships of the identified risks within the RLSC for DWM operations. It has not targeted a specific construction material or any secondary production, which could be practiced through a case study in future research. The results encourage the investigation of RLSC process quality by maintaining the relationship between recycler and customer to enable a safe workplace environment. Hence, the role of relevant practitioners and government is inseparable in supporting decision-making. Future research could discuss the impact of those inter-related risks in relation to time- or cost-related operational performance criteria. This study contributes to the field through presenting the first major study on the identification and assessment of the inter-dependencies of the risks in the RLSC in South Australia. The RLSC process mapping had been identified as a tactical and operational management approach. However, the risk management process is a strategic management approach. Therefore, the integration of both process mapping and the risk management approaches in one platform is germane to construction management research.

Abstract: In light of the increasing detrimental effects on sustainability, the reverse logistics supply chain (RLSC) has emerged as one of the remedies in the construction industry, whereby the bulk of demolition waste (DW) is returned into the production cycle. Quality assurance (QA) plays an important role in RLSCs, which needs an information-rich environment enriched with external stakeholders’ influence strategies. However, due to ineffective external stakeholders’ influence, useful information is not available, making macro-level uncertainties for QA. Given this, the current study aimed to identify the macro-level uncertainties for QA in the RLSC of DW. The study used a qualitative approach involving 21 semi-structured interviews representing five external stakeholder categories. The study found the regulatory uncertainties are the root causes that propagate through incentivizing and contractual uncertainties to influence QA in the RLSC. The external stakeholders could employ measures such as ‘reforming regulatory instruments’, ‘employing effective incentivizing schemes’ and ‘active involvement of forward supply chain actors’ to minimize uncertainties at their source. The external and internal stakeholders can use these findings as a roadmap to determine suitable measures to overcome macro-level uncertainties in the RLSC. Furthermore, the study paved an avenue to integrate stakeholder theory and organizational information processing theory (OIPT) in future research.

Abstract: A significant amount of work has been performed in the area of identification of factors affecting construction productivity. Previous studies have tried to determine the most important factors affecting construction productivity in different countries for a long time. As a result of continuous effort in this direction, researchers have identified a wide range of factors. While the subject area has matured, no general agreement could be made on the factors affecting construction productivity. To fill this gap, the purpose of this paper is to undertake a comprehensive systematic review of mainstream studies on factors affecting construction productivity published in the last 30 years (1986–2016). A total of 46 articles from different sources such as journals, conference proceedings, dissertation and PhD theses were identified and thoroughly reviewed. Gaps in research and practices are discussed and directions for future research have been proposed. The literature review indicates that despite noticeable differences in the socio-economic conditions across both developed countries and developing countries, an overall reasonable consensus exists on few significant factors impeding productivity. These are, namely, non-availability of materials, inadequate supervision, skill shortage, lack of proper tools and equipment and incomplete drawing and specifications. Nevertheless, implications of technology, site amenities, process studies, project culture, and impacts of physiological and psychological factors were not adequately covered in existing literature. The study also found that traditional construction projects have remained the main focus of these studies while green construction projects have been generally overlooked. The review does not include studies that report productivity at the organisational or industry level as well as total factor productivity. The scope of the review is limited to work on identification of factors affecting productivity at the activity level in construction projects. The outcomes of this study would help researchers and practitioners by providing the findings of previous studies in a concise manner. It is also expected that presenting a deeper and wider perspective of the research work performed until now will direct a more focussed approach on productivity improvement efforts in the construction industry. This review paper undertakes a comprehensive systematic review of studies on identification of factors affecting construction productivity published during the last three decades.

Abstract: The purpose of this paper is to analyse the policy instruments used by the China's Government on prefabricated construction (PC) development, with the aim to clarify the pattern and discover the focus of the policy instruments using the methods of bibliometric analysis and content analysis. Through a thorough screening by all researchers, 25 policies were identified from 1995 to 2021 were selected and analysed. The external attribute analysis clarified the issuing year, organisation, and the format of each policy. The content analysis was adopted firstly to analyse the policy instrument. An analysis framework including environmental instruments, supply instruments and demand instruments was applied in categorising and counting of each policy instrument. The bibliometric analysis was then carried out to extract keywords of the policy instruments, construct a co-word network and complete the cluster analysis. The results indicate that the policies lack consistency and had relatively low authority. The results of content analysis show that the policy system relies heavily on environmental and supply instruments, whilst the use of demand instruments seems to be grossly inadequate. The results of the bibliometric analysis identify the core ideas of each policy instrument category, discuss the existing problems and then put forward the corresponding countermeasures. This study comprehensively and systematically analysed the policy instruments on facilitating the development of PC in China which broaden the research perspectives of the PC development by introducing the methods of political science. The research findings afford helpful information for future policy adjustments and elucidate the effective delivery of policies to facilitate PC development for developing countries. This study provides an in-depth understanding of policy instruments used by China's Government on PC development. By integrating the policy instrument analysis framework into the mixed methods of content analysis and bibliometric analysis, this study provides an innovative way to conduct policy instrument analysis.

Abstract: Severe air pollution associated with the rapid urbanization is a pressing issue in China. Moreover, the public awareness of environmental protection in China is awakening, which poses enormous pressure on governments to enforce environmental regulations. The study of environmental problems from the public perspective plays a crucial role in effective environmental governance. The Baidu search engine is the China's largest search engine. The search index of haze based on Baidu search engine reflects the public concern on air quality in China. The aim of this study is to uncover important relationships between public concern and air quality monitoring data based on the case study of haze pollution crisis in China. The results indicate that: (1) the year 2013 is the turning point of the public concern on air quality in China (2) according to daily data analysis, the search index of haze has increased progressively with increased PM

Abstract: This paper aims to investigate the practices, drivers and barriers which influence the implementation of green leases in South Australia. Despite some efforts on legal aspects of green leases, only a few studies have examined these aspects from an operational perspective. In addition, very little empirical evidence was presented in previous studies to show how green leases work in real-life settings. Data were collected using semi-structured interviews with landlord and tenant representatives who have considerable experience in green leases. These interviewees were selected via a purposive s ling technique that identified buildings which use green leases in South Australia. The concept of interface management (IM) was used to operationalize this research. The green leases were found to be mainly initiated by tenants while government involvement, economic and environmental benefits are the main drivers in South Australia. Drivers such as staff retention, well-being and corporate social responsibility are found to be more relevant to tenants. Lack of awareness and transaction costs are the main barriers to the implementation of green leases. This study focuses on the South Australian context and mainly covers dark green leases. There are implications for the government’s continued involvement and the promotion of lighter shades of green leases to overcome operational issues and barriers identified in this study. This study contributes to the body of knowledge on the subject of green lease implementation from an operational perspective. In addition, the study introduces a conceptual framework via IM that could be used in future research endeavours.

Abstract: The purpose of this paper is twofold: first, to investigate strategies that external stakeholders can employ to affect construction project outcomes and, second, to identify essential requirements for utilising each strategy. A new theoretical framework of stakeholder influence strategies was proposed and applied. The research design is a multi-case study, comprising four cases in the construction industry in Vietnam. Seven specific strategies were found, including inputs withholding, inputs compromising, communication, direct action, coalition building, conflict escalation and credibility building. When possessing project inputs, stakeholders can affect a project directly via a withholding or compromising strategy. Communication is available to those who have basic communicating skills however, direct action is only employed by groups that include a large number of members. Objectors must have common interests or goals with their potential allies for using coalition building. Conflict escalation is restricted to communities having distinctive characteristics which can be used to create new problems sensibly, while credibility building is used by parties possessing adequate resources and expertise. This study’s generalisability may be limited by the main source of data and the types of projects in the selected cases. This study provides directions for project managers to predict stakeholder influence by taking project inputs and utilisation requirements of the strategies into consideration. This study is one of the first investigations on stakeholder-attributes-related requirements for utilising influence strategies in projects.

Abstract: Agribusiness supply chain (ASC) risk is currently a major business problem throughout the world. The current trend of globalisation has affected every business, and supply chain risks have become a concern in logistics and other business processes. Current risk management strategies must address a variety of global and local challenges. To tackle this issue, existing research has analysed risks in agrifood supply chains, ASC risk management, disruption in ASCs, risk assessments of agriculture supply chains and sources of risk facing an agricultural supply chain. However, the existing research has not defined and categorised risks as a basis for managing risks in ASCs. Therefore, the definition and categorisation of risks in the ASC has been overlooked. To address this gap, this paper undertakes a systematic literature review, offering constructs to define and categorise risks in ASCs, and develops a novel taxonomy in ASC risks to enrich future research on ASC risk management. Sixty-one articles from six databases published between 2000 and 2020 underwent descriptive and thematic analysis.

Abstract: The chapter summarizes the educational pedagogy researched and developed in the OnSite project, a multi-year trial of a blended virtual learning environment, situating it in the context of immersive learning environments generally and discussing the specific challenges in designing and creating environments suitable for introductory construction courses. It documents and reports the challenges in creating a virtual learning environment (VLE) for use within an introductory construction course for architecture and building students at the University of South Australia. In addition, the chapter will reflect on issues of technical development for immersive learning environments, discussing the purpose and value of high-fidelity modelling, texturing, and lighting to achieve learning “authenticity.” Finally, the chapter looks at the implications for VLEs of this sort in terms of larger issues regarding the potential for game engine (GE) environments as cooperative spaces within the AEC industry.
