Abstract: The construction industry is facing constant pressure to improve its poor safety record and low productivity rate. A significant amount of research has been undertaken to identify the best practices to enhance productivity and safety. Nevertheless, the mainstream research in the field of construction focuses on one of these issues rather than implementing a holistic approach to resolve them. Consequently, the interactions between productivity and safety cannot be fully understood. Recent studies have demonstrated that management strategies and practices for improving labour productivity can trigger a series of unintended consequences that affect safety performance in construction projects. However, the behavioural aspects of these unintended consequences have yet to be investigated. This research addresses the gap by measuring the impacts of seven management strategies for improving labour productivity on the safety behaviour of construction labourers. A total of 191 construction labourers participated in a survey designed based on the Management Strategy Assessment Index (MSAI). The results show that the implemented management strategies for improving labour productivity have a greater impact on shaping safety compliance (SC) behaviours than safety participation (SP) behaviours of labourers. This study took a further step by breaking down the management strategies to their constitutive practices and measuring their impacts on SC and SP, and labour productivity. This paper provides further insight into the complex relationship between the productivity and safety behaviour of construction labourers. The findings can help project managers to improve labour productivity without harming their safety unintentionally.

Abstract: The purpose of this paper is to investigate the literature on resilience factors applied to post-disaster reconstruction projects and to develop a guiding framework to assist in their strategic selection and application. A systematic review was undertaken on the literature’s account in four major bibliographic databases to elicit resilience factors contributing to improving post-disaster reconstruction projects' robustness. Through summative content analysis and open-coding of research outputs over the past decade, the factors identified informed the development of a conceptual framework that can significantly impact the built environment’s resilience development process. The review found 24 resilience factors open-coded into five criteria groups: governance, innovations, reconstruction approaches, resource management and stakeholder expectations. While these factors have influenced reconstruction projects, the recently increased participation of clients and end-users in construction management accentuates their strategic selection and applications. The research focused on English language articles therefore, any claim to a comprehensive resilience factors listing can be amiss. The framework provides a platform for developing clear measurement indicators for allocating project resources and determining resilience deficiencies. Results confirm the designs and assessment of a resilient built environment extends beyond the traditional structural characteristics, but includes the ability of the integrated network of buildings and infrastructure to support the continuous delivery of the community’s social and economic services in normal and post-disaster settings. The review is very specific as it attempts to develop a novel conceptual framework for guiding developers and practitioners in the application of resiliency to post-disaster reconstruction projects.

Abstract: Previous safety climate studies primarily focused on either large construction companies or the construction industry as a whole, while little is known about whether company size has significant effects on workers' understanding of safety climate measures and relationships between safety climate factors and safety behavior. Thus, this study aims to: (a) test the measurement equivalence (ME) of a safety climate measure across workers from small and large companies (b) investigate if company size alters the causal structure of the integrative model developed by Guo, Yiu, and González (2016). Data were collected from 253 construction workers in New Zealand using a safety climate measure. This study used multi-group confirmatory factor analyses (MCFA) to test the measurement equivalence of the safety climate measure and structure invariance of the integrative model. Results indicate that workers from small and large companies understood the safety climate measure in a similar manner. In addition, it was suggested that company size does not change the causal structure and mediational processes of the integrative model. Both measurement equivalence of the safety climate measure and structural invariance of the integrative model were supported by this study. Practical applications: Findings of this study provided strong support for a meaningful use of the safety climate measure across construction companies in different sizes. Safety behavior promotion strategies designed based on the integrative model may be well suited for both large and small companies.

Abstract: Contract administrators play essential roles in the construction sector, as they administrate the execution of construction contracts. A contract administrator acts as a representative of clients and an independent certifier to contractors. This dual role can bring conflicts within the contract administrator’s duty. Therefore, concerns have been raised whether contract administrators can perform their duties fairly and impartially when serving clients and contractors. This study examines the independence and impartiality of contract administrators in the construction sector. This study also reviews the current New Zealand standard construction contract forms to understand the role and position of contract administrators. A questionnaire survey was conducted in New Zealand to obtain views from 42 construction practitioners. The survey results suggest that independence and impartiality of contract administrators may exist in the New Zealand construction sector, manifesting that most survey respondents experienced a reasonable and fair performance from contract administrators when carrying out their duties. This study contributes to the existing knowledge of contract administration by revealing the existence of independence and impartiality of contract administrators in the New Zealand construction sector. Also, this study contributes to industrial practices by putting forward concerns and recommendations to improve the legal obligations of contract administrators in construction contract forms.

Abstract: This paper aims to explore augmented reality (AR) applications in construction safety academic literature and propose possible improvements for future scholarly works. The paper explicitly focuses on AR integration with Construction 4.0 technologies as an effective solution to safety concerns in the construction industry. This study applied a systematic review approach. In total, 387 potentially relevant articles from databases were identified. Once filtering criteria were applied, 29 eligible papers where selected. The inclusion criteria were being directly associated with construction safety focused on an AR application and AR interactions associated with the Construction 4.0 technologies. This study investigated the structure of AR applications in construction safety. To this end, the authors studied the safety purposes of AR applications in construction safety: pre-event (intelligent operation, training, safety inspection and hazard alerting), during-event (pinpointing hazard) and post-event (safety estimation) applications. Then, the integration of AR with Construction 4.0 technologies was elaborated. The systematic review also revealed that the AR integration has contributed to developing several technical aspects of AR technology: display, tracking and human–computer interaction. The study results indicate that AR integration with construction is effective in mitigating safety concerns however, further research studies are required to support this statement. This study contributes to exploring applications and integrations of AR into construction safety in order to facilitate the leverage of this technology. This review can help encourage practitioners and researchers to conduct further academic investigations into AR application in construction safety.

Abstract: Over recent years, the issue of corruption in the public construction sector has attracted increasing attention from both practitioners and researchers worldwide. However, limited efforts are available for investigating the underlying factors of corruption in this sector. Thus, this study attempted to bridge this knowledge gap by exploring the underlying factors of corruption in the public construction sector of China. To achieve this goal, a total of 14 structured interviews were first carried out, and a questionnaire survey was then administered to 188 professionals in China. Two iterations of multivariate analysis approaches, namely, stepwise multiple regression analysis and partial least squares structural equation modeling were successively utilized to analyze the collected data. In addition, a case study was also conducted to triangulate the findings obtained from the statistical analysis. The results generated from these three research methods achieve the same conclusion: the most influential underlying factor leading to corruption was immorality, followed by opacity, unfairness, procedural violation, and contractual violation. This study has contributed to the body of knowledge by exploring the properties of corruption in the public construction sector. The findings from this study are also valuable to the construction authorities as they can assist in developing more effective anti-corruption strategies.

Abstract: Labor productivity and safety are important topics in the construction industry. Even so, the literature provides little information for project managers trying to determine how management strategies designed to improve labor productivity impact safety. This research addresses the gap by measuring the impact of two groups of management strategies that involve human resource related management strategies and construction related management strategies related to safety performance in construction projects. Data were collected from 111 general construction projects through the survey. The results show that the relationship between the implemented management strategies and safety performance is nuanced with 'Communication' harming safety performance while implementation of 'Labor Management,' 'Supervision and Leadership,' 'Planning' and 'Management of Construction' strategies improve the level of safety performance. This study took a further step by measuring the impact of the interactions between the two groups of management strategies on safety performance. The results show that the interactions of construction and human related management strategies are not always in the favor of safety. Practical Applications: This paper adds to the literature on the relationship between productivity and safety in the construction industry. The research findings can assist project managers to improve labor productivity without harming the safety of laborers unintentionally.

Abstract: In the construction sector, site excavation is one of the most dangerous and challenging activities. Proper training can be an effective way to mitigate excavation hazards. Virtual reality (VR) has been used as an effective training tool to enhance safety performance in various industries. However, little attention has been paid to the potential of this technology for construction excavation safety training. This study proposes an immersive VR training system for excavation safety and hazard identification. The proposed VR training system was compared with a health and safety manual via a controlled experiment. Results based on scores obtained immediately after training indicate that VR training significantly enhanced practical performance, knowledge acquisition and self-efficacy. Results also show that knowledge was retained four weeks after training. In addition, VR training outperformed health and safety manuals regarding knowledge retention. This study measures the practical performance to evaluate the effectiveness of the proposed VR training system. Also, this study compares the VR training system with a traditional training method by measuring knowledge acquisition and retention. The results demonstrate the potential of VR as a training tool for excavation safety and hazards.

Abstract: – In construction, the involvement of complex human interactions and incompatible interests among negotiating parties would pose as an obstacle in any negotiation process. The purpose of this paper is to examine the role of face in governing the behaviour of negotiating parties. – This paper identified the generic types of face-saving tactics used by construction negotiators, investigated the tactic-outcome relationships and examined the effects of face-inducement factors on these relationships with the use of moderated multiple regression (MMR). – A taxonomy of face-saving tactics has been developed by employing the technique of principal component of factor analysis. The results suggest that the use of face-saving tactics in construction negotiation would statistically result in an achievement of mutual agreement, maintenance of harmony and avoidance of offending situations. The MMR models finally affirm that some tactic-outcome relationships would significantly depend on the face-inducement factors. – This research highlights the usefulness of face-saving tactics in construction negotiation. – The findings revealed that these tactics can help facilitate the achievement of mutual agreement, maintain harmony and avoid offending situations. In this connection, an awareness of the proper use of face-saving tactics is worth-noticing in order to have successful dealings in negotiating project disputes. – In construction, there are some distinct features which may influence the use of face-saving tactics and the behaviour of project dispute negotiators. The findings of this research would provide an insight into promoting proactive and collaborative project dispute resolution.

Abstract: Construction safety management involves complex issues (e.g., different trades, multi-organizational project structure, constantly changing work environment, and transient workforce). Systems thinking is widely considered as an effective approach to understanding and managing the complexity. This paper aims to better understand dynamic complexity of construction safety management by exploring archetypes of construction safety. To achieve this, this paper adopted the ground theory method (GTM) and 22 interviews were conducted with participants in various positions (government safety inspector, client, health and safety manager, safety consultant, safety auditor, and safety researcher). Eight archetypes were emerged from the collected data: (1) safety regulations, (2) incentive programs, (3) procurement and safety, (4) safety management in small businesses (5) production and safety, (6) workers' conflicting goals, (7) blame on workers, and (8) reactive and proactive learning. These archetypes capture the interactions between a wide range of factors within various hierarchical levels and subsystems. As a free-standing tool, they advance the understanding of dynamic complexity of construction safety management and provide systemic insights into dealing with the complexity. They also can facilitate system dynamics modelling of construction safety process.

Abstract: The construction industry needs to move towards more relational procurement procedures to reduce extensive losses of value and avoid conflicts and disputes. Despite this, the actual conceptualization and assessment of relationships during conflict and dispute incidents seem to be neglected. Via a review of literature, relationship quality is suggested as a systematic framework for construction projects. General system theory is applied and a framework consistent of four layers respectively labelled as triggering, antecedent, moderation and outcome is suggested. Two different case studies are undertaken to represent the systematic framework which verifies that changes in contracting circumstances and built environment culture can affect the identified layers.Through system reliability theories a fault tree is derived to represent a systematic framework of relationship quality. The combinations of components, causes, and events for two case studies are mapped out through fault tree. By analysing the fault tree the combination of events that lead to relationship deterioration may be identified. Consequently the progression of simple events into failure is formulized and probabilities allocated. Accordingly the importance and the contribution of these events to failure become accessible. The ability to have such indications about relationship quality may help increase performance as well as sustainable procurement. Paper Type: Research article

Abstract: The aim of this paper is to review and analyze the research literature on the health and safety issues of migrant workers in the construction industry from 2000 to 2022. 5 steps method is used to conduct a systematic review to achieve the objectives. After scanning two authoritative search engines “Web of Science” and “Scope”, 60 articles are selected from 225 publications for identification and review. These identified articles are classified by research fields, countries and time span. The review finds that with the increasing influence of migrant construction workers, the number of publications on the health and safety of migrant workers has shown a rapid upward trend. Moreover, language barriers are the most dominant safety risk factors encountered by on-site migrant workers. This systematic literature review also summarizes the definition of migrant workers and solutions to reduce safety risk factors. The research data on the health and safety issues and risk factors of migrant workers in the construction industry is still limited. This literature review summarizes the research trends and contributions of the literature in this field in the past 22 years and provides theoretical support for future research on the safety management of the migration construction field.

Abstract: With growing concern about sustainable development and increased awareness of environmental issues, digital technologies (DTs) are gaining prominence and becoming a promising trend to improve productivity, sustainability and project performance in the construction industry. Nonetheless, the uptake of DTs in the construction industry has been limited and plagued with roadblocks. This study aims to identify critical barriers for construction organisations to adopt DTs and to demonstrate relationships between organisational characteristics and the perceived DTs adoption barriers. This study adopted an explanatory sequential design by combining the advantages of quantitative and qualitative data. Data collection methods include literature review, a pilot study, questionnaire survey, and semi-structured interviews. Questionnaire data were analysed by using SPSS and multivariate regression technique. The interview data were processed by using content analysis to validate and supplement findings from the questionnaire. Based on the survey and interview results, eight critical barriers were identified: the three top critical barriers are (1) “status quo industry standards”, (2) “lack of client interest” and (3) “lack of financial need/drive for using DTs”. The eight critical barriers were further classified into technical, environmental, and social dimensions to determine the major constructs that hinder DTs adoption. A theoretical framework articulating critical barriers with underlying components and root causes was also proposed. Furthermore, by using multivariate regression analysis, a model was developed to link the organisational characteristics with barriers to DTs adoption. By referring to the framework and the model developed, academics, industry practitioners, and decision makers can identify pivotal areas for improvement, make informed decisions and implement remedial measures to remove the barriers to digitalisation transformation. This study contributes to the literature on construction innovations by investigating barriers to DTs adoption holistically as well as perceptions of the impact of organisational attributes on these barriers. It establishes the groundwork for future empirical research into the strategic consolidation of movement of DTs adoption and diffusion.

Abstract: – The purpose of this study is to develop a conceptual framework of bidding model for maintenance contractors. Sustainability is closely linked with the maintenance of facilities or infrastructure. From maintenance contractor’s perspective, one of their key business processes is to bid projects under fierce competition. Their competitiveness is critically affected by their bidding behaviours and bid makeup selections. – This paper aims at identifying critical and important objectives of bidding and items affecting bidding strategies and developing a bidding model for maintenance contractors. – With the questionnaire surveys of 50 maintenance contractors, two critical objectives of bidding have been identified. Likewise, a total of eight critical and 12 important items affecting bidding strategy have also been identified. A bidding model for maintenance contractors is presented. – This model formulates the maintenance contractors’ bidding behaviors in a rational manner, and acts as a guideline to new and less experienced maintenance contractors to have a brief understanding about the bidding process and to assist them for establishing their own bidding strategies. With this knowledge, clients or maintenance contractors themselves would become easier to achieve their sustainability goals. – Many academic researches on contractor’s bidding strategy emphasized on the general building works, and less attention has been given to maintenance works. Because of the fact that the community is awash with sustainability, and sustainability development is closely related to maintenance work, the business operation of maintenance contractors should be understood. This shall contribute to the achievement of sustainability goals for the society.

Abstract: Being an insidious risk to construction projects, collusion has attracted extensive attention from numerous researchers around the world. However, little effort has ever been made to assess collusion, which is important and necessary for curbing collusion in construction projects. Specific to the context of China, this paper developed an artificial neural network model to assess collusion risk in construction projects. Based on a comprehensive literature review, a total of 22 specific collusive practices were identified first, and then refined by a two-round Delphi interview with 15 experienced experts. Subsequently, using the consolidated framework of collusive practices, a questionnaire was further developed and disseminated, which received 97 valid replies. The questionnaire data were then utilized to develop and validate the collusion risk assessment model with the facilitation of artificial neural network approach. The developed model was finally applied in a real-life metro project in which its reliability and applicability were both verified. Although the model was developed under the context of Chinese construction projects, its developing strategy can be applied in other countries, especially for those emerging economies that have a significant concern of collusion in their construction sectors, and thus contributing to the global body of knowledge of collusion.
