Abstract: The objective of this paper is to present the identified underlying antecedents of problems unique to the procurement of airport infrastructure and recommend initiatives for their management. This research is significant due to the importance of airports in economic growth through improving the logistics of both freight and people. This paper first presents the typical characteristics of airport infrastructure procurement. It then focuses on the main issues with project procurement method selection and management of stakeholders involved within an airport infrastructure project. A case study of stakeholder industry practitioners involved in a Western Australian airport terminal project was then undertaken to reveal issues with current practices encountered during its planning, design and construction phases. Their management strategies and control techniques were also compared. The planning phase in particular was found to have the greatest influence over the nature and severity of issues encountered within the airport terminal project later on. This paper suggests that these issues could be mitigated if properly managed at the project level from the outset.

Abstract: This study aims to develop a Stackelberg Game Model for seeking the optimal subsidy plans with varying levels of government financial capability (GFC). Furthermore, the scenario-based analysis is conducted and will enable governments to identify a comprehensive subsidy plan as follows: improve project performance and optimise social welfare. A Stackelberg Game Model is developed to optimise the effectiveness of subsidies on the performance of public-private partnerships (PPPs). According to the scenarios that are generated from the model, governments that are confronting with limited public budgets could reduce the intensity of performance incentives and increase the participation-oriented subsidy. Whilst a participation-oriented subsidy can stimulate private organisations’ willingness to participate in infrastructure PPPs, a performance-oriented subsidy is capable of facilitating the projects’ performances. Intuitively, the performance-oriented subsidy enables the private entities of PPPs to improve their efforts on the projects to realise higher profits. However, the participation-oriented subsidy is unable to affect the level of their effort spent on the projects. To satisfy both parties’ expectations in a PPP, the performance-oriented subsidy needs to be prioritised for a purpose of enabling higher quality outputs. The game model developed in this study contributes to the literature by offering new insight into the underlying mechanism of governments and private entities, in terms of their decision-making for subsidy planning and contributions (i.e. resource allocation and spending) during the life-cycle of PPPs. This research enriches the government subsidy model by revealing the effects of the GFC and clarifies the impacts of two different schemes of subsidy on the performance of PPPs. The government has been conventionally viewed as being omnipotent to provide PPPs with a wide range of subsidies. However, the subsidies are not unlimited, due to GFC. In addressing this void, this study has modelled the impacts of government subsidy plans with a consideration of GFC-related constraints. The combined effects of the participation- and performance-oriented subsidies on the project performance of PPPs have been examined.

Abstract: The purpose of this study is for examining the evolution of stakeholder influence and the trans-period effect (TPE) of process performance of public–private partnerships (PPPs). TPE refers to the ripple effect of project performance across different phases of a PPP. Social network analysis is used to analyze each stakeholder’s influence on PPP performance. For examining the TPE, partial least squares structural equation modelling is conducted. The performance in the five phases (e.g. initiation and planning, procurement, construction, operation and transition) of PPPs exhibits significant TPE. The stakeholder network varies in different phases. The most influential stakeholder is a public authority, followed by a public initiator and a private consortium. The project type of PPPs is not considered in the stakeholder network analysis. Future work should focus on developing a multidimensional stakeholder network by considering the typology of the project. Moreover, the TPE cannot reflect the relationships between the KPIs in the different phases, and thus, further study is required. This research provides a useful tool for measuring the life cycle outputs and outcomes of PPPs through enhanced process-oriented performance measurement. The developed PMS enable practitioners to have a better understanding of the process performance of the projects and then ensure informed decision-making about actions to be required and taken to improve future performance. This study contributes to knowledge of performance management by simultaneously addressing the process and stakeholder management theories within the context of PPPs. The proposed PMS provides an insight into managing stakeholders’ influences to enhance the life cycle performance of PPPs.

Abstract: Modular construction is considered a well-established construction method for improving the efficiency of the construction industry worldwide. However, the industry struggles to achieve higher levels of modularisation in urban areas. Previous studies on decision-making for modularisation have, so far, not focussed much on its application in urban areas. As modular construction could bring lots of advantages such as speed of construction, This study aims to develop a decision-making tool that can assist the project planners in deciding whether the modular construction techniques should be applied in their urban area project. Based on the literature review, a total of 35 decision-making factors of modularisation were identified for this study. The decision-making model is then developed to evaluate the significance of each factor using the analytic hierarchy process (AHP) approach. A total number of 72 valid responses were obtained and analysed. The geometric mean of priorities is adopted to obtain the par-wise comparison between the critical factors in which each factor’s weighting in the decision-making model is calculated. Afterwards, the robustness of the decision-making model is demonstrated by the real-life projects in China, Hong Kong and the UK, respectively. A total of 35 decision-making factors allocated in five criteria for modular construction selection in urban areas were identified. The criteria include site attributes, project characteristics, labour consideration, environmental and organisation and project risk. Their impact was calculated using the AHP to indicate the relative importance with respect to the adoption of modularisation in urban areas. Afterwards, a two-level decision-making model was developed that can be used as a decision-making tool for the adoption of modular construction. The outcome of this research will be beneficial to industrial practitioners and academics in understanding the critical attributes that affect the adoption of modular construction in an urban area. It further enables the building professionals to assess the feasibility of using modular construction in their projects, especially at the early stage, so as to facilitate its use. There is a number of literature on the decision-making model on the adoption of modular construction. However, previous studies did not provide specific concerns related to urban areas, whereas there is an urgent need to have an updated analysis that can be catered to the modular construction in the urban area. In this research study, the 35 decision-making factors were ranked by the experienced project managers and then a pair-wise comparison was conducted. With this information, the robust decision-making model is formulated to offer a kept promised indicator in adopting modularisation in the urban area.

Abstract: Studies on market convergence are well considered in the literature. However, the majority of the previous research focused on housing markets and few studies have concentrated on construction markets. Owing to a simultaneously dramatic increase in the construction prices of the sub-markets in the building construction sector in Australia, this paper aims to identify the convergence among these markets, involving house construction market, other-residential building construction market, and non-residential building construction market. To achieve it the Granger causality test and generalized response function depending on the vector error correction model with the quarterly data of Australia’s eight states from 1998 to 2010 will be applied. Based upon the econometric tests, the price diffusion patterns among these construction markets have been identified. Research on the convergences of construction markets not only helps construction firms perform well in business operations and arbitrage activities, but also provides policy makers with useful information for enacting effective construction policies for national perspectives and approaches to infrastructure planning.

Abstract: This paper develops a platform that can be used to determine how to effectively and efficiently deal with a large number of temporary facilities under a constrained site condition(s). The ultimate goal is to reduce the material handling costs between transformation phases of construction works occurring during the project's development period. Empirical and deductive research is first adopted to mathematical model dynamic site layout planning using the branch and bond algorithm (B& B). Second, a real-life construction project is examined to illustrate how dynamic site layout planning (using the aforementioned B& B algorithm and a computer software program called LINGO) can reduce the material handling costs. The application of the proposed methodology is then showcased against a case study that utilizes a comparative analysis between the “dynamic” and “statistic” site planning approaches. By iding the construction period into different phases, the developed model is shown to be capable of optimizing the material handling costs between the phases of transformation during construction works. Optimal costs are also considered using the site boundary and unit cost for moving construction materials between two facilities. The comparative analysis results illustrate that the B& B algorithm reduces material handling costs by 33%. The proposed model offers an effective planning algorithm for the site layout and location of temporary facilities. More specifically, it can make a substantial improvement in reducing the travel time and material handling cost between the temporary facilities in the construction sites. The primary knowledge contribution of this study to the site layout is successfully deal with the unequal area problem of temporary site facilities and incorporates the concept of dynamics site planning into the algorithm.

Abstract: This study aims to develop a collaborative governance framework (CGF) to systematically investigate the impeding factors (IFs) in terms of the operational sustainability of PPPs. It examines the transmission pattern (i.e. the way in which network members react to each other) of the IFs network. Literature review and interview were adopted to identify the IFs. Then, with the data collected from the interview in China, the social network analysis and interpretive structure model were synergised to examine the chain reaction, driving and dependent powers, and hierarchical structure of the identified IFs. The results reveal that the cognition, institutional, financial and participation aspects are key barriers confronted by PPP sustainability, and the government plays a leading role in controlling factors causing sustainability-related problems in PPPs. Weak government leadership and institutional environment were identified as the most fundamental reasons triggering a chain of IFs, while project governance and management activities act as bridge nodes that play an intermediary role in the IFs network. This research contributes to the literature on PPP governance by (1) bridging the literature gap through the development of CGF for explaining the governance of PPP sustainability with a holistic view that considers both macro environment and operational project processes and (2) identifying the transmission pattern of IFs network which uncovers the underlying dynamics causing the unsustainable operation of PPPs. This research provides practitioners with a list of key checkpoints for preventing failure escalation, enables decision-makers to prioritise obstacle-mitigation efforts and develop a feasible process to control PPP operation, and offers management countermeasures to remove the key barriers impeding PPP sustainability. This study is novel for adopting network-oriented techniques to quantify the relative importance of the IFs and examine the transmission pattern of the IFs system. Therefore, it visualises the complex underlying dynamics causing unsustainable PPP operation, identifies root and direct causes of PPP failures, and provides decision-makers with insights into sustaining PPP sustainability from a network-oriented perspective.

Abstract: This study aims to examine the impacts of formal and informal hierarchical governances (HGs) on the performance of mega-projects and the mediating role of contractor behavior (i.e. perfunctory and consummate behaviors) in these relationships. A total of 375 valid data entries from managers representing 375 mega-projects were analyzed through path analysis. Both formal and informal HGs exert positive effects on the performance of mega-projects. While formal HG positively affects contractor perfunctory behavior and contractor consummate behavior, informal HG affects contractor perfunctory behavior only. Contractor behavior mediates the relationship between formal HG and project performance. The impacts of potential moderators (e.g. institutional arrangement and complexity) on the relationship between HG and contractor behavior have not been considered in this study. This study is useful for owners to enhance formal HG to improve contractor perfunctory and consummate behaviors, which in turn can enhance the performance of mega-projects. This study expands the knowledge of mega-project performance management from the perspective of HG. It also contributes to the literature of contractor behavior within the context of mega-projects.

Abstract: Pre-construction of a project comprises stages that are pivotal for the procurement performance. It is defined as the duration from the project's initiation to construction. However, Private Public Partnerships (PPPs) have been subjected to a long pre-construction, thereby leading to an inefficient development process. Therefore, the purpose of this paper is to pay attention to the influencing factors elongating the pre-construction duration. Based on data of 5,677 PPP projects between 2009 and 2021 in China, the authors adopt the Accelerated Failure Time (AFT) model in duration analysis to empirically analyze the following underlying dynamics determining the duration of PPP pre-construction stages: (1) policy uncertainty (2) corruption and (3) procurement method selection. To observe the influencing paths more specifically, the authors ided the pre-construction duration into the pre-tendering period and tendering period and regressed them separately. The results indicate that the pre-construction duration is significantly prolonged with increased policy uncertainty and corruption degree as well as the use of tendering methods. Meanwhile, the above factors have a greater impact on the pre-tendering period than the tendering period. The contribution of this study is twofold: (1) theoretically, this paper provides new evidence on the impact of PPP policy uncertainty, corruption and procurement method selection on the pre-construction duration. It complements empirical studies on the factors elongating the time efficiency of PPPs projects. (2) In practice, it provides a specific path for the government to improve the time efficiency of PPPs.

Abstract: Housing supply is an essential component of the property sector. Compared with an increasingly strong housing demand, the growth rates of total housing stock in Australia have exhibited a downward trend since the end of the 1990s. Over the same period, the significant adjustments in the Australian monetary policy were being implemented under a turbulent global economic climate. This research aims to identify the relationship between housing supply and monetary policy within the context of global economic turbulence by a vector error correction model with a dummy variable. The empirical evidence indicates that the monetary policy changes and global economic turmoil can significantly affect the supply side of the housing sector in Australia. The models developed in this study assist policy makers in estimating the political impacts in the global context.

Abstract: Sponge city (SPC) is currently being promoted as an initiative under the principle of sustainable development to solve the urban water crisis across China. Moreover, with the introduction of the public-private partnerships (PPPs) in SPC development, the public’s concern regarding SPC PPPs has increased in terms of their more sophisticated outcomes and greater social impacts than general urban development. Thus, to develop an effective set of SIA key indicators for SPC PPPs, this study uses social impact theory (SIT) to explore in greater detail the influencing mechanism for the social impact assessment (SIA) conceptual model proposed in the authors’ previous studies. Confirmatory factor analysis (CFA) was applied to examine whether the hypothesized relationships in the influencing mechanism fit the empirical data and to further consolidate the SIA key indicators. Based on a survey questionnaire and CFA results, a verified and refined SIA framework using 23 key indicators and five corresponding dimensions was proposed, particularly within the context of SPC PPPs. Implications generated from the CFA were discussed to improve the comprehensive performance of sponge city PPPs. These 23 key indicators and the clarification of their relationships to the respective SIA dimensions and to the overall SIA results can be a useful tool for enhancing the social benefits of SPC PPPs. Moreover, this study also provides governments with insights into enabling the low-impact and sustainable development of infrastructure within urban areas.

Abstract: The performance of public–private partnerships (PPPs) can be determined by a variety of factors, i.e. influencing factors (IFs). This study is undertaken for a purpose of identifying how such factors determine the project's performance (i.e. factor transmission patterns), particularly from the key stakeholders' perspectives. A hybrid approach, which comprises a Social Network Analysis, ISM (i.e. Interpretive Structural Modeling) and an improved DEMATEL (i.e. Decision-Making Trail and Evaluation Laboratory), was developed to analyze the causal relationships between the identified IFs as well as the transmission patterns of their impacts on PPPs. Data were collected from interviews and questionnaire surveys. The transmission patterns of the identified IFs cascade from project environment and features and stakeholders' relationship to the project company capabilities and project process. It is identified that the public authority has a higher level than that of the private entity in PPPs. It lacks longitudinal studies to investigate the dynamics of PPP stakeholder relationships and social networks. Future research needs to explore the transmission patterns of sub-factors affecting PPP performance and extend the applicability of the developed hybrid approach. This research provides practitioners with a robust tool that is useful for and insights into enhancing the management of lifecycle performance. It ensures the public authorities and private entities embarking on PPPs will make an informed decision about the monitoring of the life cycle performance. This study contributes to knowledge of managerial mechanisms that can be adopted to manage factors determining the performance of PPPs. It enables an understanding of stakeholders' roles in driving the life cycle performance of PPPs.

Abstract: This paper investigates the policy changes made towards infrastructure public–private partnerships (PPPs). The purpose of this study is to empirically identify the policy risks associated with the development of PPPs and to assess their impacts on the projects. A case study of the policy changes that have been implemented for PPPs in China over the past seven years has been undertaken and is presented in this study. The causal loop diagrams are applied to assess and illustrate the potential impacts of the risks as a result of such changes on PPPs. A sequence of the policy risks, which relate to PPP risk allocation, contract management and implementation, payment and abatement mechanisms and financing, has been identified. It is also found that the identified risks will generate significant but negative impacts on PPPs, leading to an ineffective project delivery, low revenue, poor service quality and even contract breach. This research provides the private-sector entities that will embark on PPPs with an insight into managing and controlling policy risks over the project's lifecycle. PPPs have been critical for infrastructure development worldwide. Nevertheless, they have been a controversy, as many of them were subjected to poor outputs. Consequently, a variety of political mechanisms has been implemented to enhance the governance for PPPs. Policy can bring not only benefits but also risks and, however, policy risks of PPPs with a particular assessment for their potential impacts have received limited attention. Therefore, the study presented in this paper will contribute to the identification and assessment of policy risks within the context of PPPs.

Abstract: – This paper reviews the normative literature of performance measurement within the context of Public-Private Partnerships (PPPs). The purpose of this paper is to examine the effectiveness of current ex post evaluations of PPPs and identify a feasible direction to comprehensively and effectively measure the performance of PPP infrastructure projects. – An in-depth literature review is conducted in this paper. The focus of the review is associated with the general performance measurement and performance measurements of PPPs. – This paper identifies that conventional ex post evaluation is not robust enough to measure the performance of PPP projects. Based on the characteristics of PPPs, the life-cycle (process-based) evaluation under performance measurement system is a promising approach to comprehensive and effective PPP performance measurement. – The outcomes of this paper can be used as a theoretical base for the development of PPP performance measurement framework. – Performance measurement is essential to business success, whether it is at the organisation or project level. Limitations on public funds have encouraged more and more governments across the world to use PPPs to procure economic and social infrastructure projects. Similar to traditional procurement, ex post evaluation is being widely used in PPP projects. However, PPPs are more complicated than other traditional procurement approaches. Exploration of literature suggests that limited research has been undertaken to examine if conventional ex post evaluation is sufficient to measure the performance of PPPs. This paper will bridge this significant knowledge gap.

Abstract: New housing supply in Australia has been experiencing a low increasing rate in conjunction with a dramatic increase in residential construction costs since the 1990s. This study aims to estimate the relationship between new housing supply and residential construction costs with the regional heterogeneities. Based on a panel error correction model, it can be identified that there is a causal link and a significant correlation between new housing supply and construction costs in the Australian sub-national housing construction markets. The model developed in this research assists policy makers to better understand the nature of the supply side of the housing sector and then enact appropriate policies to improve the new housing supply in Australia.

Abstract: The accuracy and reliability of subjectively assessing a construction project's complexity at the pre-construction stage is questionable and relies upon the project manager's tacit experiences, knowledge and background. The purpose of this paper is to develop a scientifically robust analytical approach by presenting a novel classification mechanism for defining the level of project complexity in terms of work contents (WCs), scope, building structures (BSs) and site conditions. Empiricism is adopted to deductively analyze variables obtained from secondary data within extant literature and primary project data to develop project type classifications. Specifically, and from an operational perspective, a two-stage “waterfall process” was adopted. In stage one, the research identified 56 variables affecting project complexity from literature and utilized a structured questionnaire survey of 100 project managers to measure the relevance of these. A total of 27 variables were revealed to be significant and exploratory factor analysis (EFA) is adopted to cluster these variables into six-factor thematic groups. In stage two, data from 62 real-life projects (including the layout and structural plans) were utilized for computing the factor score using the six-factor groups. Finally, hierarchical cluster analysis (HCA) is adopted to classify the projects into collected distinctive groups and each of a similar nature and characteristics. The developed theoretical framework (that includes a novel complex index) provides a robust “blueprint platform” for main contractors to compile their project complexity database. The research outputs enable project managers to generate a more accurate picture of complexity at the pre-construction stage. While numerous research articles have provided a comprehensive framework to define project complexity, scant empirical works have assessed it at the pre-construction stage or utilized real-life project s les to classify it. This research addresses this knowledge gap within the prevailing body of knowledge.

Abstract: In Hong Kong, over 20,000 private residential buildings will be 50 plus years old by 2039. However, building maintenance has not been owners’ popular interest because of the high cost as well as the complexities in justifying whether the quantities and prices of the maintenance works are reasonable. This paper therefore aims to validate the practicality of adopting Scan-to-BIM: Terrestrial Laser Scan (TLS) and Building Information Modelling (BIM) to perform quantity take-offs (QTO) for estimating building maintenance costs. A 64-year-old tenement building was selected to conduct a case study. In this instance, the building had undergone a Scan-to-BIM survey approach to generate QTO for the bills of quantities for external painting works. The Scan-to-BIM approach includes site visit, positioning of scanning equipment, assignment of circular scan routes, point cloud registration and identification of residual error. After that, time, cost and quality data were logged into contrast with QTO on as-built plans for external wall plastering works. The “time”, “cost” and “quality” of the Scan-to BIM practice were then examined and compared with the prevailing practices of manual measurements on as-built drawings. As noted from the results, the initial cost of Scan-to BIM is high, owing to the cost of equipment, software and capable available operators. However, the authors identified that the time and cost can be significantly minimised by developing and implementing efficient practices such as preparing a detailed scan plan, equipping modeller with quantity surveying knowledge, using automated object recognition and 5D BIM software packages such as Vico Office and CostX. The upshot is that Scan-to-BIM could be one of the measures to advance the clarity in the QTO and estimated price of the maintenance projects. The practicability of Scan-to-BIM has received limited attention on existing building maintenance project. The Scan-to-BIM approach was examined using a case building of a 64-year-old tenement building. The approach demonstrated in this research study is promised to advance the clarity in the QTO and estimated price of maintenance project.

Abstract: The unprecedented SARS-CoV-2 (COVID-19) pandemic has further constrained the budgets of governments worldwide for delivering their much-needed infrastructure. Consequently, public-private partnerships (PPPs), with the private sector's investment and ingenuity, would appear to be an increasingly popular alternative. Value for money (VfM) has become the major criterion for evaluating PPPs against the traditional public sector procurement and, however, is plagued with controversy. Hence, it is important that governments compare and contrast their practice with similar and disparate bodies to engender best practice. This paper, therefore, aims to understand governments' assessment context and provide a cross-continental comparison of their VfM assessment. Faced with different domestic contexts (e.g. aging infrastructure, population growth, and competing demands on finance), governments tend to place different emphases when undertaking the VfM assessment. In line with the theory of boundary spanning, a cross-continental comparison is conducted between three of the most noticeable PPP markets (i.e. the United Kingdom, Australia and China) about their VfM assessment. The institutional level is interpreted by a social, economic and political framework, and the methodological level is elucidated through a qualitative and quantitative VfM assessment. There are in idual institutional characteristics that have shaped the way each country assesses VfM. For the methodological level, we identify that: (1) these global markets use a public sector comparator as the benchmark in VfM assessment (2) ambiguous qualitative assessment is conducted only against PPPs to strengthen their policy development (3) Australia's priority is in service provision whereas that of the UK and China is project finance and production and (4) all markets are seeking an amelioration of existing controversial VfM assessments so that purported VfM relates to project lifecycles. As such, an option framework is proposed to make headway towards a sensible selection of infrastructure procurement approaches in the post COVID-19 era. This study addresses a current void of enhancing the decision-making process for using PPPs within today's changing environment and then opens up an avenue for future empirical research to examine the option framework and ensuing VfM decisions. Practically, it presents a holistic VfM landscape for public sector procurers that aim to engage with PPPs for their infrastructure interventions.

Abstract: Public–private partnerships have become an integral strategy to deliver infrastructure projects in Australia. Yet, public–private partnerships have been plagued with controversy due to recurrent time and cost overruns. The paucity of an approach to evaluate the performance of public–private partnerships throughout their life-cycle has hindered the ability of governments to manage their effective and efficient delivery. This paper examines the practice of evaluation for a hospital and prison that were delivered using public–private partnerships. The empirical evidence indicates that with public–private partnerships: (1) performance is typically measured during the construction and operation phases using time, cost and quality and a restricted number of key performance indicators and (2) a process-based and stakeholder-oriented measurement approach would be better suited to evaluate performance. Building upon the extant literature and the findings emerging from ‘practice’ (i.e. actual activity, events or work), a Performance Prism for ameliorating the evaluation of public–private partnerships throughout their lifecycle is proposed. The research presented in this paper provides stakeholders of public–private partnerships, especially governments, with a robust framework for governing and future proofing their assets to ensure value for money.

Abstract: This study aims to address the gap by empirically exploring how residential construction-production progress, which includes project commencement, under-construction and project completion, responds dynamically to fluctuations in house prices. A vector autoregressive model and an impulse response function are applied to simulate and analyse the circle of the stage-responsiveness of residential construction to residential property price dynamics in the state of Victoria, Australia. The quarterly numbers of dwelling units commenced, under-construction and completed are used as the proxy for the residential construction activities at three stages over the construction progress. The analysis indicates that the dynamics are essentially transmitted throughout the construction process and can substantially impact the pace of production progress. The findings from this study provide an empirical base that should be useful in developing price-elasticity and production theories applicable to the context of residential property construction. The findings described above have been generated basically by examining the case of Victoria, Australia at a macro level. The generalisation of the research output needs to be verified further by future researchers using data collected from other regions/countries. Nevertheless, the reliability of the conclusions with particular practical implications can be substantially improved by future researchers by analysing more markets and production proxies at the activity level. Based on new empirical findings, this research argues that building activity (i.e. under construction) played as a gateway between the construction and housing sectors, via which the inter-responsiveness of the housing supply in terms of construction activities and housing prices are transmitted. This research firstly attempts to explore the inter-responsiveness between the real estate and construction sectors. A simulated circle of the stage-responsiveness of residential construction to residential property price dynamics is proposed, which can serve as a significant foundation for developing the theory of construction production.

Abstract: The construction industry in developed economies is suffering from a shortage of workers, triggering project cost escalations and project delays and suppressing the whole economy. This paper aims to explore the perceptions of the general public and construction workers towards workforce shortages in the Hong Kong construction industry and identifies the critical factors affecting their intention to join the industry. The triangulation approach was adopted in this study and a street survey was conducted in grass-roots areas in Hong Kong. The questionnaire was formatted using a five-point Likert scale and semi-structured interviews with ten experienced workers were used to validate and interpret the results from the street survey results. The triangulation approach found that ‘harsh working conditions’, ‘job instability’ and ‘lack of career prospects’ are the primary barriers dissuading the public to join the construction industry. This paper provides insights into the critical factors affecting the construction workforce supply and identifies possible solutions for maintaining a sufficient workforce.
