Investigation into the hierarchical nature of TQM variables using structural modelling
Publisher: Emerald
Date: 03-04-2017
DOI: 10.1108/IJQRM-04-2015-0052
Abstract: The purpose of this paper is to provide the empirical evidence supporting the existence of a multi-level hierarchical TQM model showing the structural inter-relationships among a total of 16 TQM variables (i.e. drivers, enablers and outcomes). The set of identified TQM variables is the product of an in-depth review of the literature, and a robust reiterative process of verification and validation. Inter-relationships among the TQM variables were subjected to the scrutiny of a panel of experts, and were used as a basis for developing a web-based survey to explore the existence as well as strength of the structural relationship between each and every pair of the identified variables using interpretive structural modelling and MICMAC (Impact Matrix Cross-Reference Multiplication Applied to a Classification). TQM variables were classified and clustered based on their influence and dependence on each other. Variables such as commitment by top management and customer satisfaction appear to have a strong chance to affect change, whereas variables such suppliers and competitors are very dependent on, and sensitive to, the evolution of the influent variables. The paper demonstrates a multi-level TQM model encompassing all identified TQM drivers, enablers, and outcomes. The paper not only addresses a gap in the relevant literature (reduces the evidence scarcity about the hierarchical nature of TQM variables), but also gives insights into the variables with most driving power needing greater management attention.

Factors affecting the bid/no bid decision in the Palestinian construction industry
Publisher: Emerald
Date: 03-08-2010
DOI: 10.1108/13664381011063421
Abstract: The purpose of this paper is to identify and rank the factors that affect the bid/no bid decision according to their relative importance from the perspective of the contracting parties operating in the Gaza Strip, Palestine. The objectives of this research were investigated through a postal questionnaire, which covered a randomly selected s le of 63 contractors, 29 clients and 13 consultants operating in the construction industry in the Gaza strip. The questionnaire was structured based on related literature, the pilot study and actual factors affecting bidders' decisions to bid or not that arise from special conditions in the Gaza Strip. A total of 78 factors that affect the bid/no bid decision were identified. These factors were then ranked according to their relative importance to contracting parties operating in the Gaza Strip, Palestine. The results illustrate that the financial capability of the contractors, the financial capability of the clients, the financial values of the project, the due date of the payments, the availability of construction raw materials in local markets, and the stability of the construction industry were the most critical factors affecting the bid/no bid decision, as agreed by all respondents. The paper provides supportive practical solutions for contractors, clients and consultants to enhance and improve bidding decisions. It is recommended that clients and consultants consider the financial capabilities, technical capabilities and staff competencies of the contractors during the awarding stage, and not simply focus on the lowest bid.

Improving consistency evaluation in fuzzy multi-attribute pairwise comparison-based decision-making methods
Publisher: World Scientific Pub Co Pte Lt
Date: 08-2014
DOI: 10.1142/S0217595914500249
Abstract: A typical approach to handle the complexity of multi-faceted decision-making problems is to use multi-attribute decision-making (MADM) methods based on pairwise comparisons. Fuzzy set theory has also been employed to cope with the uncertainty and vagueness involved in conducting the comparisons between components of a decision model. An important issue regarding the reliability of the output is the consistency of pairwise comparisons provided by the decision maker(s). Using the MADM method developed by Lu et al. (2007) as a foundation, this paper proposes an algorithm for evaluating the consistency level of pairwise comparison matrices, where linguistic data are used. A crisp numeric scale has been introduced to consider the priority of linguistic data and to avoid the complexity of handling fuzzy calculations in consistency evaluation of pairwise comparison matrices. As an advantage, the proposed method of consistency evaluation is capable of assessing the degree of inconsistency among the pairwise comparisons. Therefore, the acceptance or rejection of the pairwise comparisons can be determined based on the desired degree of tolerance in accepting inconsistent judgments. An application of a revised MADM method is then demonstrated in a case study involving flood mitigation project selection in Australia.
Thermal environment effects on construction workers’ productivity
Publisher: Emerald
Date: 11-2002
DOI: 10.1108/00438020210441849
Abstract: This paper reports on a research study that focused on predicting the loss of construction workers’ productivity due to thermal environment variations. The paper utilises a statistical polynomial regression analysis to establish a relationship between productivity and the predicted mean vote (PMV) thermal comfort index. In doing so, it builds upon a substantial amount of data reported in the literature regarding construction productivity and thermal environment. A set of equations reflecting the nature of the construction task being performed as well as the thermal environment are proposed to predict the degree of change in workers’ productivity, according to a change in the thermal environment. The paper also reports on an experimental investigation undertaken to validate the developed equations. Validation results indicate that the developed equations can predict productivity with a reasonable level of accuracy. Furthermore, they show that the workers’ productivity decreases as the PMV index moves away from the optimum range for all the observed tasks.

Occupational Stressors and Safety Behaviour among Oil and Gas Workers in Kuwait: The Mediating Role of Mental Health and Fatigue
Publisher: MDPI AG
Date: 07-11-2021
Abstract: This paper provides an examination of direct and mediated relationships among occupational stressors (responsibilities towards family and living environment), mental health (anxiety and depression), fatigue (physical and mental fatigue), and safety behaviour (safety compliance and safety participation). In this cross-sectional study, data were collected by means of a questionnaire among oil and gas workers (foreign employees working at a remote oil and gas field site located in Kuwait), during a two-month period (November–December 2018). Regression analyses (bivariate and hierarchical), carried out on 387 responses, were employed to test the links between occupational stressors, mental health, fatigue, and safety behaviour in the hypothesised model. The results provide support for the direct relationship in the model, in that both responsibilities towards family and living environment predicted safety behaviour participation. Further, the results provide partial support for the mediated relationships in the model, as mental health and fatigue were found to mediate the relationship of responsibilities towards family and living environment with safety participation behaviour. It is concluded that occupational stressors have a negative effect on safety behaviour, while mental health and fatigue can operate as risk factors. Given this, it is recommended that organisations need to enhance remote oil and gas workers’ safety behaviour by encouraging them to effectively balance their stress, mental health, and level of fatigue. This can be achieved by actions such as promoting spirituality, boosting workers’ resilience, providing recreational facilities and encouraging communications.
Assessment of sea‐level rise adaptation options
Publisher: Emerald
Date: 23-08-2013
Abstract: The Gold Coast is a low‐lying coastal Australian city and many residential areas are subject to 1:100 year flood events. Evidently, there is a need for the city to adapt to sea‐level rise (SLR) by developing more effective policies to reduce its destructive impacts. Thus, the purpose is to identify and evaluate preferred adaptation alternatives to reduce the vulnerability to SLR and storm surges. In this research, we explore stakeholders’ opinions for adaptation alternatives to adapt to the impacts of SLR. As part of exploring alternatives to improve Gold Coast's resilience to climate change effects we are undertake a multi‐criteria analysis by using the analytical hierarchy process (AHP). The goal, criteria and adaptation alternatives were derived, and based upon, adaptation programmes, existing adaptation works by local governments and an extensive literature review. The final AHP structure was developed after further consultations with three local stakeholders (politicians, experts and residents). The results show that across the three stakeholder groups, effectiveness and sustainability are the criteria of highest priority, respectively. When considering adaptation alternatives, the highest priority for politicians and residents is improving building design whilst for experts improving public awareness is of most importance. We demonstrated that utilising the AHP method in the aforementioned context for the Gold Coast region could provide a straightforward approach to evaluate the adaptation alternatives from multi‐stakeholders’ perspectives. Advantages are its versatility in application to coastal processes and its inclusion of the multiple stakeholder in the decision‐making process.

Exploring the Role of Digital Infrastructure Asset Management Tools for Resilient Linear Infrastructure Outcomes in Cities and Towns: A Systematic Literature Review
Publisher: MDPI AG
Date: 29-10-2021
DOI: 10.3390/SU132111965
Abstract: Linear infrastructure such as roads, railways, bridges and tunnels enable critical functionality within and between metropolitan and regional cities and towns, facilitating the movement of goods and services, as part of vibrant, thriving economies. However, these asset types are typically challenged by costly asset management schedules and continually eroding maintenance and refurbishment budgets. These challenges are compounded by the increasing frequency and intensity of disruptive events such as fire, floods, and storm-surge that can damage or destroy property. The United Nations Sustainable Development Goal 9 (SDG-9) highlights the urgent need for enabling evidence-based decision making for infrastructure asset management (IAM). Around the world, digital engineering (DE) efforts are underway to streamline the capture, processing, and visualization of data for IAM information requirements, towards timely and evidence-based decision support that enables resilient infrastructure outcomes. However, there is still limited understanding about which IAM information can be digitized and the types of tools that can be used. This study sought to address this knowledge gap, through reviewing the extent of available and emerging linear infrastructure related DE technologies and their IAM information requirements. A systematic literature review elicited 101 relevant conceptual and empirical papers, which were subsequently evaluated with regard to the extent and characteristics of digital infrastructure asset management tools. Findings are discussed using three themes that emerged from the analysis: (1) DE tools and their IAM asset information requirements (2) Interoperability and integration of DE tools across IAM platforms and (3) Application of DE tools to enable resilient linear infrastructure outcomes. A ‘Digital Technology Integration Matrix’ is presented as an immediately useful summary for government and industry decision-makers, particularly in the field of disaster management preparedness and recovery. The Matrix communicates the synthesis of tools and likely end-users, to support effective data gathering and processing towards more timely and cost-effective infrastructure asset management. The authors conclude with a research roadmap for academics, including recommendations for future investigation.
IT/IS projects selection using multi-criteria utility theory
Publisher: Emerald
Date: 10-2002
DOI: 10.1108/09576050210436101
Abstract: In recent years, there has been a growing awareness that most decision makers are not only concerned with the financial implications of information technology/system (IT/IS) projects, but they are also concerned with other objectives such as competitive advantage, market share and future growth. Nowadays, multi‐criteria decision‐making methods are gaining importance due to their inherent ability to judge different alternative scenarios for possible selection of the best alternative. This paper provides a decision‐making framework for senior executives when selecting innovative IT/IS projects. The proposed framework is based on the multi‐criteria utility theory (MCUT) combined with information economics principles to select IT/IS project(s) based on “business value” and “risk” criteria. MCUT has the advantage of taking into consideration the decision maker’s preferences in the form of utility functions defined over a set of tangible and intangible criteria. To illustrate the application of the proposed framework, a hypothetical case study is provided, where input elicited from four engineering professionals is used to develop utility functions for a predefined set of selection criteria.
An experimental study of the behaviour of sleeved bolt connections in precast concrete frames
Publisher: Thomas Telford Ltd.
Date: 06-1995
DOI: 10.1680/MACR.1995.47.171.119
Abstract: Sleeved bolt beam-to-column connections have been used in the precast concrete industry for many years. They have advantages over other jointing methods in component production, quality control, transportation and assembly. However, there is at present limited information concerning their detailed structural behaviour under shear loading. The study reported in this paper was undertaken to elucidate the behaviour of such joints under symmetrical vertical loading. Two series of full-scale tests were preformed on s le columns for which the column geometry and bolt arrangements conformed with successful commercial practice. The first series of tests was used to investigate the influence of bolt density on the ultimate load, failure mode and stiffness of such connections. The second test series showed the influence of varying concrete strength and the effectiveness of the confining reinforcement. Full details of these test programmes are given. The finite element modelling technique was used to develop three-dimensional models which were calibrated against the test observations. These models subsequently provided complete stress and deformation distributions within the joint components at intervals up to the ultimate load, and are the subject of another paper.
Validation of an empirical model for innovation diffusion in Australian design firms
Publisher: Emerald
Date: 09-10-2009
DOI: 10.1108/14714170910995976
Abstract: The paper is an extension to a previous empirical study that models the process of innovation diffusion in Australian architectural and engineering design (AED) firms. This paper aims to utilise explanatory case studies to assist in the verification of this empirical model that depicts pathways that explain the role of enabling “climate for innovation” constructs in determining the level of innovation diffusion outcomes (IDO), and subsequent business performance (BPM) in Australian AED firms. This paper presents the latter of a two‐stage sequential mixed method research design: quantitative empirical study and qualitative explanatory case studies. Specifically, this stage extracts findings from five explanatory case studies using a qualitative pattern matching analysis technique. Interview‐based data collected from the case studies are analysed to formulate the relationship patterns between constructs, which are then compared with those predicted by the empirical model. This approach affords a determination on the extent to which the case‐based findings (i.e. work‐setting phenomena) explains (i.e. validated) the empirical model. The results of the case studies on five Australian AED firms indicate that the model can be adequately explained by the actual phenomena. This is evident in four of the cases providing a good to perfect match, and one showing a partial match to the predicted patterns of relationships between the model constructs. Thus, the paper presents verified empirical pathways for AED firms, which suggest that, by increasing the level of leadership for innovation, the level of team climate and organisational culture for innovation can be improved. The improved culture for innovation will then heighten the level of IDO, which can in turn, result in an enhanced BPM. This paper expands and improves upon the current understanding of how the diffusion of innovation can be accelerated within the AED firm context. By focusing on the socio‐psychological processes, the paper depicts the pathways to improve IDO and BPM through fostering a robust climate for innovation. These pathways have been constructed empirically and are verified in this paper under real‐work settings. Based on the validated model and the specific insights derived from the explanatory case studies, the paper also highlights a number of strategic implications for AED firms seeking to enhance their BPM through improving innovation diffusion practices.

An Integrated DPSIR-SD Framework for Sustainability Assessment of Roads in Australia
Publisher: MDPI AG
Date: 10-06-2022
DOI: 10.3390/SU14127142
Abstract: The Australian Sustainability Development Goals (SDGs) Summit in 2018 attracted much-needed national attention towards environmental goals and targets compared with other aspects of sustainability. Road infrastructure is the backbone of modern society and plays a crucial role in accomplishing a targeted balance between these aspects of sustainability and achieving the SDGs. This article presents an integrated sustainability performance assessment methodology that acts as a decision support tool. A series of two conceptual modelling techniques—drivers—pressure—state—impact—response (DPSIR) and system dynamics (SD)—is employed, with the cause-and-effect relationships of the sustainability indicators developed utilising the DPSIR framework, and a quantitative analysis carried out through a subsequent SD model. The end result is the generation of a Sustainability Performance Index (SPI) for road infrastructure created by analysing the SD model and DPSIR index layer relationship. The benefits and applicability of the proposed methodology are validated through case study analysis. The overall aim is to determine restricting factors and response strategies influencing road infrastructure and transport sustainability performance during the operation and maintenance phase. Thus, a significant contribution is made through the proposed methodology for assessing factors influencing the long-term achievement of the SDGs.

DOI: 10.1108/14635779610149151
Abstract: States that the benefits of benchmarking are still largely unrecognized in the construction industry, despite the fact that the best practice concept has been indirectly investigated by both practitioners and researchers. Notes that some confusion seems to exist in construction circles as to what exactly benchmarking is and what it can achieve to improve productivity. Addresses the benchmarking concept and its application to construction and presents a three‐level internal, project and external framework for benchmarking current practice. The three levels are examined in detail, with an illustration of the need to adapt to improve construction productivity. Uses a generic definition of benchmarking throughout to ensure applicability to the different and many aspects of the construction process.

Factors affecting accuracy of cost estimation of building contracts in the Gaza Strip
Publisher: Emerald
Date: 08-2005
DOI: 10.1108/13664380580001069
Abstract: Estimating is a fundamental part of the construction industry. The success or failure of a project is dependent on the accuracy of several estimates through‐out the course of the project. Construction estimating is the compilation and analysis of many items that influence and contribute to the cost of a project. Estimating which is done before the physical performance of the work requires a detailed study and careful analysis of the bidding documents, in order to achieve the most accurate estimate possible of the probable cost consistent with the bidding time available and the accuracy and completeness of the information submitted. Overestimated or underestimated cost has the potential to cause loss to local contracting companies. The objective of this paper is to identify the essential factors and their relative importance that affect accuracy of cost estimation of building contracts in the Gaza strip. The results of analyzing fifty one factors considered in a questionnaire survey concluded that the main factors are: location of the project, segmentation of the Gaza strip and limitation of movements between areas, political situation, and financial status of the owner.

Abstract: Construction projects located in the Gaza Strip, Palestine suffer from many problems and complex issues. Consequently, the objective of this paper is to identify the factors affecting the performance of local construction projects and to elicit perceptions of their relative importance. A comprehensive literature review was deployed to generate a set of factors believed to affect project performance. A total of 120 questionnaires were distributed to 3 key groups of project participants namely owners, consultants and contractors. The survey findings indicate that all 3 groups agree that the most important factors affecting project performance are: delays because of borders/roads closure leading to materials shortage unavailability of resources low level of project leadership skills escalation of material prices unavailability of highly experienced and qualified personnel and poor quality of available equipment and raw materials. Based on these findings, the paper recommends that: 1) project owners must work collaboratively with contractors and facilitate regular payments in order to overcome delays, disputes and claims 2) project participants should actively have their input in the process of decision‐making and 3) continuous coordination and relationship between project participants are required through the project life cycle in order to solve problems and develop project performance.

The role of climate for innovation in enhancing business performance: The case of design firms
Publisher: Emerald
Date: 05-09-2008
DOI: 10.1108/09699980810902712
Abstract: Innovation and the process of diffusion have been widely acknowledged as hinging upon the complex social psychological process. Invariably, such a process manifests itself in the form of “climate” in an organisation, which influences people's behaviours. The purpose of this paper is to empirically investigate the roles of a facet‐specific climate, namely “climate for innovation” in determining innovation‐related outcomes. In particular, this paper focuses on interrelationships and roles of specific constructs forming such climate. Additionally, this paper attempts to determine the efficacy of innovation by examining the relationship between outcomes of innovation diffusion and business performance. A conceptual model incorporating three climate for innovation constructs including leadership, team, and organisational culture along with two constructs addressing innovation diffusion outcomes and business performance was developed. Statistical analyses, specifically exploratory factor analysis (EFA) and structural equation modelling (SEM), were conducted based on the data collected from a questionnaire survey of 181 design professionals employed in Australian architecture and engineering design (AED) firms. EFA was employed as a preliminary step to ascertain the factors underlying each construct, and SEM was sequentially utilised to determine the factor structure of the model and to assess the relationships between model constructs. The results revealed that perceived organisational culture functions as a gateway to the diffusion of innovation, by mediating the relationships between leadership and team climate, and innovation diffusion outcomes. More importantly, it was found that all pathways to innovation diffusion outcomes originated from the leadership construct, highlighting its critical role in creating a supportive culture that fosters and nurtures innovation. Finally, the findings warranted the benefits of innovation by demonstrating its significant contribution to business performance in AED firms. The study presents an empirically developed model depicting pathways that explain the mechanisms of climate for innovation constructs in determining the degree of innovation diffusion outcomes and business performance. The model can potentially form the foundations of a framework for firms seeking to diagnose their existing condition and use such findings to enhance the diffusion of innovation that could, in turn, strengthen their business performance.

DOI: 10.1108/02621711111105786
Abstract: The purpose of this study is to investigate the relationship between leadership behaviors and knowledge management (KM) practices. More specifically, it aims to examine the influence of transformational and transactional leadership behaviors on KM, and the moderating effect of organizational culture on this relationship, in the context of small‐to‐medium sized enterprises (SMEs) operating in Australia. A total of four hypotheses were proposed for testing. It also provides is a succinct review of KM basics relevant to the study, the relationship between leadership and KM, and leadership and organizational culture. The results suggest that both transformational and transactional leadership are positively related to KM practices. They also reveal that charismatic leadership and contingent reward leadership behaviors have greater influence on all the dimensions of KM practices. A key limitation of this study is its cross‐sectional nature. It is possible that at least certain aspects of leadership and organizational culture, and its impact on KM practices emerge with some kind of time lag. A longitudinal treatment of data might yield additional insights into the impact of leadership behaviors and organizational culture. This study was also unable to actually observe managers interacting with followers. The results of the study are generally consistent with theoretical predictions based on extant research. The results of this study provide compelling evidence in support of the moderating role of organizational culture on the relationship between transactional leadership and KM and will be of interest to those in the field.
Evaluating the COVID-19 Impacts on Sustainable Procurement: Experiences from the Australian Built Environment Sector
Publisher: MDPI AG
Date: 31-03-2022
DOI: 10.3390/SU14074163
Abstract: The COVID-19 pandemic has brought global economies to a standstill and created challenges for a variety of sectors, including housing, building and infrastructure. Many business and government organisations have experienced some form of supply chain disruption—either through suppliers going offline, a sudden spike in demand or both. While embedding sustainability in procurement is a powerful tool for bringing about positive change in an organisation’s supply chains, this global pandemic has had a myriad of impacts on these procurement processes. Through focus group discussions with industrial practitioners and government decision makers from the Australian built environment sector, this study presents their lived experiences related to COVID-19 impacts on sustainable procurement. The emergent themes are: (1) the effects of COVID-19 on sustainable procurement, (2) the rapid development of reactive procurement responses and (3) levers for post-COVID-19 sustainable procurement. In order to learn from the challenges related to COVID-19, both government and industry need to re-assess their supply chain risks and determine the supply chain design that will deliver the most resiliency in the event of another large-scale disruption. There are several key levers, including developing reliable, transparent and local supply chains, leveraging innovative tools and digital engineering approaches, creating a coalition between government and industry and assessing risks at multiple levels. This study is the first of its kind to evaluate the COVID-19 impacts on sustainable procurement in the Australian building and construction industries. Government and industry practitioners can immediately apply these actionable recommendations to overcome the impacts of the pandemic and other disruptions on sustainable procurement activities.

Hong Kong construction foremen’s safety responsibilities: a case study of management oversight
Publisher: Emerald
Date: 02-2003
DOI: 10.1108/09699980310466523
Abstract: In total, 69 foremen from 13 Hong Kong construction companies were invited to participate in a study designed to investigate foremen’s opinions regarding 27 safety supervisory tasks. These fell into six categories, including handling new workers, training, safety, discipline, coordinating, and motivating. Results of the survey and subsequent follow‐up interviews showed that over two thirds of foremen claimed that they had the responsibility to perform certain tasks but only half said that they had the authority to perform these tasks. Further interviews and on‐site observations of foremen were then conducted in order to validate the findings by way of case study material. It is concluded that foremen play a key role in ensuring that safety management systems operate effectively. It appears, from the results of the study, that this role is not being performed properly and that the key interface between worker and management, the role of the foreman, is not paid sufficient attention by senior management and is an area requiring urgent attention if Hong Kong’s poor site safety record is to be improved.

DOI: 10.1108/09699980810852655
Abstract: This paper sets out to describe the development and empirical testing of a structural equation model of construction safety culture. A key contribution of the model is providing insights into the interactions among safety culture enablers, and the relation between those enablers (what the organisation is doing) and safety culture goals (what the organisation aims to achieve) in the context of the Thai construction industry. Based on the internationally recognised EFQM Excellence model, this paper empirically examines the interactions and causal relationships between five enablers (i.e. Leadership, Policy and strategy, People, Partnerships and resources and Processes) and safety outcome (i.e. Goals). The paper utilises the structural equation modelling technique to test the hypothesised positive inter‐relationships between the enablers and goals. A questionnaire survey was administered to a s le of construction contracting organisations operating in Thailand to elicit opinions on the different attributes in the context of their current safety practices and performance. Supported by empirical evidence, this study established that firstly, the Leadership enabler directly influences the implementation of Policy and Strategy, however, its effect on Partnerships and Resources appears to be an indirect one secondly, Partnerships and Resources was found to indirectly affect Processes through Policy and Strategy, which likewise appears to be indirectly influenced by the People enabler. This study provides a greater understanding of the interactions between the key elements of safety culture (enablers and goals), and among the enablers themselves.

An example of developing a business model for information and communication technologies (ICT) adoption on construction projects - The National Museum of Australia project
Publisher: Emerald
Date: 06-2003
DOI: 10.1108/09699980310478430
Abstract: Effective use of information and communication technologies (ICT) is necessary for delivering efficiency and improved project delivery in the construction industry. Convincing clients or contracting organisations to embrace ICT is a difficult task, there are few templates of an ICT business model for the industry to use. ICT application in the construction industry is relatively low compared to automotive and aerospace industries. The National Museum of Australia project provides a unique opportunity for investigating and reporting on this deficiency in publicly available knowledge. Concentrates on the business model content and objectives, briefly indicates the evaluation framework that was used to evaluate ICT effectiveness.
Resource allocation for strategic quality management: A goal programming approach
Publisher: Emerald
Date: 09-03-2012
DOI: 10.1108/02656711211216135
Abstract: The purpose of this paper is to assist organizations in understanding the nature of quality management from a resource‐based perspective by investigating the relationship between strategies needed to drive quality enhancement, and resources being allocated to support effective strategy implementation. The resource‐based view of TQM elements led this case study research to deal with quality management from a strategic viewpoint, or what is known as Strategic Quality Management (SQM). The paper employs the analytic network process (ANP) to model the interactions between eight SQM strategies and the three types of resources (human, organisational and technological) needed for effective strategy implementation. The paper then formulates a goal programming (GP) model in order to identify the extent to which each single strategy is inhibited by a lack of (or overloaded by) resources. Using a case study approach, the hybrid ANP‐GP methodology is employed to illustrate the application in the context of enhancing quality in the food‐processing industry. The ANP analysis quantitatively differentiates between the amount of resource support each strategy receives and the support it needs. The GP model offers insight on how to re‐allocate resources to minimize identified discrepancies related to how the company utilizes their resources. This paper argued that practicing QM with the consideration of the firm's strategic need for resources provides better understanding of why quality gurus still disagree on whether soft or hard TQM is more connected to organizational performance. Therefore, rather than focusing on “generalizing” the TQM model, as has traditionally been done in previous attempts, the main contribution of this paper is to propose a methodology that assesses a firm's utilization of resources considering its strategic need for these resources.

Drivers affecting household residents’ water and related energy consumption in residential buildings
Publisher: Emerald
Date: 08-05-2017
DOI: 10.1108/IJBPA-01-2017-0002
Abstract: The Gaza Strip in Palestine is suffering from a shortage of water and energy. To manage the current situation and address future issues, practical approaches need to be adopted to enhance water and energy efficiency. The purpose of this paper is to elicit professionals’ perceptions of the drivers affecting water and related energy consumption in residential buildings in the Gaza Strip. In total, 19 drivers were identified from previous research and modified according to the results of a pilot study. These drivers were ranked under a Relative Importance Index (RII). A questionnaire survey was then administered and non-random purposive s ling used. The population of this study comprised stakeholders, including the United Nation Refugee Work Agency, Gaza Strip Governorates Municipalities, and the Coastal Municipalities Water Utility. The results of all drivers (i.e. RII=71.43 per cent, mean=3.57) indicated that the respondents agreed about which drivers were affecting water and energy consumption. The sign Test-value was a positive 4.55 and the p -value was 0.000 (i.e. smaller than the level of significance a =0.050). The means of these drivers differed significantly and were greater than the hypothesised value of 3. Accordingly, it was concluded that the drivers investigated significantly affected household residents’ consumption of water and energy in residential buildings. The study revealed that climate changes, knowledge of how to conserve water and energy and household size were the most important drivers affecting household residents’ consumption of water and related energy in residential buildings. The study will assist the parties concerned about water and energy use to be aware and understand the drivers affecting water and related energy the consumption in order to provide household residents with the necessary knowledge to ensure conservation and sustainability. Although this study related to a narrow geographical area in Palestine, the findings could be useful to similar locations in the Middle East and Africa. This research demonstrates the drivers affecting water and related energy the consumption in residential buildings in the Gaza Strip which is considered the first study in Palestine and in the region. The study provides a useful platform for the development of appropriate water and energy strategies in Palestine and other similar geographical locations in the Middle East.
An empirical investigation into the link between information technology implementation barriers and coping strategies in the Australian construction industry
Publisher: Emerald
Date: 09-2004
DOI: 10.1108/14714170410815079
Abstract: The need for the improved implementation of information technology (IT) has been identified in both empirical and highly structured research studies as being critical to effective innovation and development at an industry and enterprise level. This need is greater in the construction industry as it has been relatively slow to embrace the full potential of IT‐based technologies. In an attempt to understand why the construction industry lags other industries in the uptake and effective implementation of IT, this study reports on an investigation of the Australian construction industry, which identifies the impediments or barriers to IT implementation and the most effective coping strategies to overcome them. A questionnaire‐based research approach was adopted for this purpose and a total of 134 valid survey responses were received from various architectural, engineering and construction professionals. The questionnaire was designed to identify perceptions of the most significant barriers to IT implementation and to determine the most “practical” and “effective” corresponding coping strategies to mitigate their effects at three decision‐making levels: Industry Organization and Project.
Integrating disaster management planning into road infrastructure asset management
Publisher: Thomas Telford Ltd.
Date: 12-2021
Abstract: Climate change presents challenges for road infrastructure asset managers, with uncertainty about the impacts of increasingly frequent and intense disasters on asset functionality and lifespan. Budgeting for disaster response and recovery is improving however, there are calls for more evidence to support budget allocations. This exploratory study aimed to create a systematic approach for integrating climate-related disaster risks within road asset evaluation, towards improving the evidence-base for capital works and maintenance budgets. It involved a systematic literature review of 63 research papers about resilient road infrastructure, followed by sense-checking key findings through eight semi-structured interviews with road asset management experts from the Australian government and industry. The authors present a set of 15 parameters for evaluating road infrastructure resilience, within four commonly used asset management categories: robustness, redundancy, resourcefulness and rapidity. These are placed within a disaster management planning framework for resilient road infrastructure outcomes, with the key parameters matched to the commonly used disaster management phases of ‘Prevent, Prepare, Respond, Recover’. The parameters and the framework have immediate use for road infrastructure asset managers, providing clear decision-support regarding what data are important to collect and analyse and at what time, to inform capital works and maintenance budgets.
Developing a Personal Leadership Competency Model for Safety Managers: A Systems Thinking Approach
Publisher: MDPI AG
Date: 15-02-2022
Abstract: The roles of all levels of management in influencing safety, particularly in a complex work environment, are crucial. Therefore, safety managers need to develop leadership competencies (i.e., effectiveness in terms of person-oriented behaviours) to reinforce their influencing capabilities through their safety responsibilities. However, practising leadership behaviours without considering how and when these behaviours should be executed is not enough. Therefore, this paper develops a personal leadership competency model by adopting the Systems Thinking approach. The model was developed by conducting exploratory factor analysis and confirmatory factor analysis of three behavioural leadership competencies (emotional, social and cognitive) selected to fulfil the holistic view of Systems Thinking. Data were collected via self-administered questionnaire surveys. A total of 180 valid responses were received from construction managers responsible for overseeing site safety. The statistical results revealed three factors belonging to emotional competency—achievement orientation and adaptability, positive outlook, and emotional self-control. Regarding social competency, four factors represented it—teamwork, organisational awareness, coach and mentor, and conflict management. Finally, cognitive competency was found to be formed by two factors—interaction recognition and pattern recognition. All nine identified factors should, in combination, help safety managers to achieve a better understanding of themselves, of others and of their worksite environments.

Project stakeholder’s engagement and performance: a comparison between complex and non-complex projects using SEM
Publisher: Emerald
Date: 09-07-2021
DOI: 10.1108/BEPAM-11-2020-0181
Abstract: The large number of stakeholders in a project is a source of complexity because their inter-relationships can lead to complex interactions, an inadequate understanding of the other stakeholders and conflicting stakeholder interests. Although several studies have investigated the role and effects of engaging stakeholders in improving project success, studies examining the relationships between stakeholder engagement (SE) and quantitative and qualitative project performance (PP) in complex projects (CPs) have been limited. This study empirically examined the relationships between SE and project performance within complex and non-CP contexts. The study used an extensive literature review to develop the conceptual model. The study identified 22 factors of measuring SE and project performance’s association within the context of CPs. The literature review followed by a questionnaire survey to collect data from quantifying the relationships. One hundred forty-four responses were received from project managers in different locations. The response data were subjected to structural equation modelling analysis. Confirmatory factor analysis was applied to evaluate the measurements model. The current study generated several key findings. In the context of CPs, SE was found to negatively affect quantitative PP but to positively and significantly affect qualitative PP. In non-CPs, SE also positively affects qualitative PP. Further, in the context of CPs, SE negatively affects schedule performance, whereas no significant relationship was found between the two variables in non-CPs. In terms of cost performance, no significant relationship was observed between SE and cost performance for either group. This research provides insight into differences in the relationship(s) between SE and PP in non-complex and CPs. The research also makes recommendations for project team members.

Developing a comprehensive safety performance evaluation framework for Saudi schools
Publisher: Emerald
Date: 08-04-2014
DOI: 10.1108/IJPPM-05-2013-0096
Abstract: – The purpose of this paper is to empirically develop a safety performance (SP) framework for evaluating the various leading and lagging indicators of SP in Saudi public schools. – A comprehensive review of the safety and performance evaluation literature enabled the formulation of the constructs, factors and items that underpinned a conceptual SP evaluation framework. The research method involved a conceptual framework review and refinement process with 18 experts, followed by a questionnaire survey of 200 respondents from Saudi public schools. The final form of the SP evaluation framework was determined through a rigorous statistical analysis process, including exploratory factor analysis to uncover the underlying framework architecture from a relatively large set of items, and then the application of the partial least squares method to confirm framework adequacy and to assign loading coefficients. – The developed SP evaluation framework for Saudi schools included five constructs, namely, safety management and leadership, safety learning and training, safety policy, procedures, and processes, workforce safety culture and SP. – The developed SP evaluation framework is proposed for implementation by the Saudi Ministry of Education to better monitor and manage school safety in the future. – This SP evaluation framework is one of the first to holistically evaluate SP in schools, particularly in the Saudi Arabian context.
Determining the causal relationships among balanced scorecard perspectives on school safety performance: Case of Saudi Arabia
Publisher: Elsevier BV
Date: 07-2014
DOI: 10.1016/J.AAP.2014.02.002
Abstract: In the public schools of many developing countries, numerous accidents and incidents occur because of poor safety regulations and management systems. To improve the educational environment in Saudi Arabia, the Ministry of Education seeks novel approaches to measure school safety performance in order to decrease incidents and accidents. The main objective of this research was to develop a systematic approach for measuring Saudi school safety performance using the balanced scorecard framework philosophy. The evolved third generation balanced scorecard framework is considered to be a suitable and robust framework that captures the system-wide leading and lagging indicators of business performance. The balanced scorecard architecture is ideal for adaptation to complex areas such as safety management where a holistic system evaluation is more effective than traditional compartmentalised approaches. In developing the safety performance balanced scorecard for Saudi schools, the conceptual framework was first developed and peer-reviewed by eighteen Saudi education experts. Next, 200 participants, including teachers, school executives, and Ministry of Education officers, were recruited to rate both the importance and the performance of 79 measurement items used in the framework. Exploratory factor analysis, followed by the confirmatory partial least squares method, was then conducted in order to operationalise the safety performance balanced scorecard, which encapsulates the following five salient perspectives: safety management and leadership safety learning and training safety policy, procedures and processes workforce safety culture and safety performance. Partial least squares based structural equation modelling was then conducted to reveal five significant relationships between perspectives, namely, safety management and leadership had a significant effect on safety learning and training and safety policy, procedures and processes, both safety learning and training and safety policy, procedures and processes had significant effects on workforce safety culture, and workforce safety culture had a significant effect on safety performance.

Utilizing the balanced scorecard for IT/IS performance evaluation in construction
Publisher: Emerald
Date: 09-2001
DOI: 10.1108/14714170110814578
Abstract: Leading organizations do not stop at the gathering and analysis of performance data rather, these organizations use performance measurement to stimulate improvement efforts and successfully translate strategy into action. In other words, they use performance measurement for managing their organizations. The most commonly used performance evaluation tool, the balanced scorecard (BSC) has been used extensively in the manufacturing, government, banking, retail, insurance and financial services sectors. This paper looks at potential applications and benefits of using the BSC as a framework to evaluate the performance improvement resulting from IT/IS implementation by a construction organization. The paper firstly seeks to adapt the original BSC concept to construction and then attempts to develop a performance measurement framework in the form of a tiered “Construct IT” BSC. The developed framework allows for the measurement of IT/IS performance at three different decision‐making tiers (i.e., project, business unit and enterprise tiers). At each tier, a group of performance indicators are used to describe key aspects of activities that occur frequently enough to warrant meaningful measurement and comparison. The proposed framework applies the analytic hierarchy process (AHP) and multi‐attribute utility theory (MAUT) to facilitate aggregating the obtained erse performance measurements, thus giving rise to an overall IT/IS performance improvement measure (score) at each decision‐making tier. To illustrate the application of the proposed framework, a project tier ex le is provided.

A gis based crash assignment model for signalized T intersections
Publisher: Trans Tech Publications, Ltd.
Date: 03-2014
DOI: 10.4028/WWW.SCIENTIFIC.NET/AMM.543-547.4472
Abstract: The crash assignment problem has long been considered as one of the most important components in an approach-level crash prediction model for intersections. A few pioneering studies have been carried out to properly assign the crashes in or nearby intersections to various approaches. However, the implementation of these models is very time consuming as it can only be done one by one manually. In this paper, a geographical information system (GIS) database is developed to complete the crash assignment. This tool has been applied in Queensland, Australia in the development of crash prediction model for signalized T-intersections.
Employee engagement, boredom and frontline construction workers feeling safe in their workplace
Publisher: Elsevier BV

DOI: 10.1016/J.AAP.2015.11.001
Abstract: Systems thinking is a philosophy currently prevalent within construction safety literature that is applied to understand and improve safety in sociotechnical systems. Among systems, the site-project organizational system is of particular interest to this paper. Using focus group and survey feedback research to learn about how safety incidents effect levels of construction workers engagement this paper reveals how a safety incident provides an opportunity to create a potential quality (productivity) upgrade within an organization. The research approach involved a qualitative study involving 27 frontline supervisors and a follow-up survey completed by 207 frontline workers in the Australian Asphalt and Pavement Industry. The focus group interviews supported the articulation of the concepts of tacit safety, explicit safety, situational awareness, foresight ability, practical intelligence and crew synergy. Our findings indicate that having regular shift changes and other job site workers being fatigued are influential on perceptions of tacit safety. An in idual's foresight ability was found to be the most potent predictor of worker perceptions of work engagement. The paper explains that relatively small improvements in worker perceptions of safety can bring about significant improvements in employee engagement and productivity.
Benchmarking masonry labor productivity
Publisher: Emerald

DOI: 10.1108/17410400710745342
Abstract: Labor productivity is one of the most important factors that affect the physical progress of any construction project. In order to improve labor productivity, site production should be measured on a regular basis, and then compared to acceptable standard benchmarks. The objective of this paper is to measure masonry labor productivity in Gaza Strip, Palestine, using a consistent benchmarking approach. Production data were collected from nine different construction projects located in Gaza. For each project, values for baseline productivity, disruption index, performance index and project management index were calculated. Based on the nine targeted projects, the baseline productivity of masonry works in Gaza seems to range from 0.29 to 0.80 work‐hours per square meter. Calculated values were utilized to develop a correlation between two project benchmarks (i.e. disruption and project management indices). AS only four out of the targeted nine projects performed reasonably well, the paper strongly recommends developing a benchmarking standard for each local construction firm in Palestine which may lead to an improvement in the national construction productivity. The outcome of this research will improve the national construction productivity in Palestine and highlights the benefit of improving benchmarking standard.
