Construction Management and Economics

Public departments of transportation (DOTs) are increasingly adopting alternative contracting methods (ACMs), such as Indefinite Delivery/Indefinite Quantity (IDIQ) agreements, to shorten project delivery and increase scheduling flexibility. However, the challenge remains to decide when an IDIQ contract would offer better value for money in a project compared to the conventional Design-Bid-Build (DBB) method. This paper proposes an IDIQ project selection framework that incorporates expected construction costs to identify suitable candidate projects. Historical bid data, an alternate cost indexing system, nonlinear regression analysis, and the Monte Carlo simulation technique are used to create and compare IDIQ and DBB probabilistic construction cost estimates. The study demonstrates the effectiveness of the framework using a single-award IDIQ granted through the Minnesota Department of Transportation (MnDOT) and past bidding information for projects awarded between January 2008 and April 2015. Additionally, the paper acknowledges the limitations of the study, including its reliance on MnDOT data, the exclusion of non-cost factors, and the assumption of project homogeneity. The study also provides valuable recommendations for future research to address these limitations and enhance the understanding and practical implementation of IDIQ contracting in the construction industry.

A substantive body of work in project studies argues that an “information flow” lens is very useful in exploring the project management of construction. This paper posits that this is even more applicable to disaster construction projects and, furthermore, lean information flow may play a role in swiftly delivering the disaster construction project. The paper uses the qualitative empirics of the delivery of the UK’s Covid surge hospital projects to demonstrate that lean information flows were employed in these projects and assisted in enabling delivery at speed. The paper also describes the autopoietic governance conditions that are necessary for lean information flows to flourish in disaster construction projects and the role that trust may play in these conditions. It warns against some of the drawbacks in enabling lean communication through autopoietic governance.

Offsite construction (OSC) transfers onsite construction activities to factory-based processes utilising technological advancements, resulting in new and emerging skills while causing some existing skills to be changed and others to be redundant. However, there are no established methods to systematically quantify these OSC skill requirements. This paper presents OSC skill prediction models while highlighting the process of model development for future research. The aim of these models is to predict skills using a comparable measure, manhours/m2. A skill classification with six skill categories was used to analyse OSC skills. Numerical model development methods were reviewed, and mixed-effect regression modelling was selected for model development. The skills data needed for regression modelling was collected using eight case studies. Predominantly panelised and modular OSC projects were used to collect skills data. The skill prediction models were validated using further case study data and an expert forum. Comparatively, modules OSC type requires higher skill quantities than panels, for all the six skill categories analysed. Onsite and offsite skill requirements vary for different OSC types. Additionally, complex, non-linear relationships were recognised between OSC types and the utilisation of their skills. This research presents unique OSC skill prediction models that can provide early-stage advice to policymakers, project planners and manufacturers on OSC skill requirements. It also provides a novel methodology to develop predictive models for specific industry scenarios that have non-linear and complex relationships.

Work in construction is highly demanding and stressful. Graduates must navigate these imminent challenges as well as the challenges associated with transition as they enter their new learning environment and seek to establish their professional identity. This research examined how resilience can support the transition of early career construction professionals from university into the workforce. Interviews were conducted with twenty-five participants and data was thematically analysed. Challenges experienced by participants related to structural and cultural conditions of working in construction as well as the transitional career stage. Internal protective factors of emotional objectivity, reflection, goal setting, and physical and mental health emerged as important in positively responding to workplace adversity. Task-related and emotion-related organisational support were considered as important external protective factors that can facilitate the development of internal protective factors. Yet, formal organisational support was often not provided. Findings can inform the design of work and workplace programs which support this new cohort of workers to adapt to an unfamiliar and demanding work environment, as well as provide guidance to university construction management programs on ways to support the development of internal protective factors of emerging professionals. Furthermore, it is expected that students transitioning from university to work, irrespective of discipline, will progress through the three stages of the liminal experience and its possible that access to protective factors supporting resilience may assist students to positively move through this process.

Over the past 3 years, the global construction sector has been severely affected by the noxious coronavirus (COVID-19) pandemic. Visionary construction stakeholders, including governments, practitioners, and academia, all have been actively devising strategies to deal with the crisis caused by the pandemic. Despite the rich contributions by academia, an in-depth review of their research works to understand how the pandemic has been handled to position the construction industry for post-pandemic actions and future pandemics is hitherto lacking. Hence, an up-to-date literature review is conducted in this study to better understand this terra incognita. It does so by adopting a six-step thematic analysis of 159 empirical peer-reviewed research articles in relation to COVID-19 on construction. The review discovered a growing research interest from different countries from 2020 to 2022. The existing studies can be put under four major topics, namely the COVID-19 impacts, challenges and opportunities, responding strategies, and post-COVID-19 interventions. A framework consisting of four categories of responding strategies, namely vaccination, personal responsibility of workers, government-instructional practices, and organisation-based approaches, is proposed through the lens of the socio-technical system theory to handle the pandemic crisis in construction. Limitations of the existing studies were further identified. Four pertinent research directions were finally proposed: building upon and testing the proposed COVID-19 response framework, adoption of more advanced innovative strategies to increase productivity amid pandemics and survive the risk of future pandemics, beyond the technological response to COVID-19 in construction, and post-pandemic view of the construction industry. This study contributes to the knowledge body by providing a candid evaluation of the knowledge contributed by academia to deal with the risks of future pandemics in the global construction industry.

The construction supervision system plays an essential role in promoting the development of Chinese construction industry. However, as the core of the supervision system, the supervisor may deviate from duty and collude with the contractor to seek more profits. This paper investigates optimal collusion governance strategies under the prevailing supervision system. This paper develops a game-theoretic framework including an owner, a supervisor and a contractor, wherein all players interact and pursue to maximize their self-profits. The collusion equilibrium and the collusion-proof equilibrium are explored. Since the game contains multiple rounds of strategic interactions, backward induction is applied to ensure subgame perfection. The results show that collusion makes the supervision system not always in the owner’s interests. For projects recommended to implement the supervision system, the boundary condition for the owner applying the supervision system is derived. For projects required mandatory supervision, the owner prefers to let the contractor and supervisor collude under certain conditions and guard against collusive behaviours otherwise. This study contributes to the theory by exploring the effects of covert collusion and optimal governance strategies. In addition, this study can assist the owner in better understanding and managing agent collusion to safeguard the project quality.

Firms modularize as they move into industrialized construction. Prior research highlights the importance of their modularization strategies, arguing that firms can either build the competence for modularization internally or can source them externally. To understand what shapes a firm's choice to use external competences in its modularization strategy, we studied three leading construction firms. In this multiple case study, Alpha, Beta and Gamma are leaders in Asian markets, using reinforced concrete solutions in high-rise industrialized construction. Where external competences are available, our analyses show the work firms do to make them reliable and that their choice to use external competences is shaped by their reliability. Alpha modularized in a context with little available external competences, so it built new competences in-house; Beta chose to use the externally available manufacturing and assembly competences, using standards, remote monitoring and control of product architectures to make them reliable for their use in modularization; Gamma had available competences in the external context and initially sought to use them, but reliability concerns led to it modularizing by acquiring the firms to bring these competences in-house. Our contribution is to show how ensuring the reliability of external competences shapes modularization strategies. Further, we have identified actions that firms can adopt to make external competences reliable through: (1) use of international standards, (2) quality control procedures, (3) control of product architectures, and 4) acquisition of external competences. We provide implications for practitioners and policy makers seeking to transition to industrialized construction; and discuss new areas for research. ARTICLE HISTORY

During the COVID-19 pandemic, several instances of innovation were reported in construction and other sectors, consistent with previously noted spikes in innovation activities during crises and environmental perturbations. Yet the behavioural mechanisms and factors leading to changes in the innovation behaviour of actors under environmental perturbation are not adequately understood. This paper studies such behavioural mechanisms and factors, building on the Excitable Innovation Behaviour Model (EIBM), which explains the voluntary or coercive change in the innovation behaviour of actors in terms of their stable state needs and excited stated needs. The findings build on data collected through an online survey (N= 266) and interviews (N=14) during the COVID situation. The results show that environmental perturbations can trigger both an increase and decrease in innovation activities. Actors' network dependencies, motivation, and years of experience influence their innovation behaviour. Environmental perturbation triggers accelerated alignment and shared prioritisation of the needs of the different stakeholders, resulting in commitment and timely actions towards innovation from each stakeholder. Actors' ability and financial stability at the time of the excitation trigger mediate their innovation behaviour, revealing similarities and differences between EIBM and Fogg's Behavioural Model of persuasion. The grounding of EIBM in behavioural theories makes it potentially generalisable and compatible with other behavioural models and theories on innovation. The underlying state-change mechanisms in EIBM also make it amenable to developing a parametric and computational model of innovation adoption and diffusion. The research insights will inform innovation management strategies, including technology adoption roadmaps in the construction sector.

Sustainable urban development districts have become an answer to the challenge of increasing urbanization while decreasing human impact on the environment. Like other domains of public administration, urban development has in recent decades moved towards heterogeneous governance. Urban development becomes project ecologies, where several construction projects are carried out in parallel and in sequence. This paper sheds light on public and private developers’ coordinating between their construction projects and the influence this has on the built environment of urban development districts. The space between projects in project ecologies is relevant to explore further to understand how the long-term goals of urban policy are achieved in practice. Through the theoretical lens of self-organizing, the discussion is informed by a qualitative study of two cases where developers built together in sustainable profiled urban development districts. The paper contributes to construction management research by illustrating how developers play a key role in finalizing the design and construction of new districts through self-organizing. In effect, new urban districts can only be realized through joint efforts and coordination amongst developers. The paper also provides policymakers with insights into how developers become key players in organizing new neighborhoods.

The “New View” of occupational safety is gaining increased attention within both the construction industry and its associated academe. With the potential to overcome the current plateau in accident rates and support the further enhancement of occupational safety on sites, the “New View” offers an alternative approach to more traditional command driven safety management and instead takes a sociotechnical perspective, valorising the workers and acknowledging their contributions to the system in the form of adaptability and resilience. Yet empirical research of “New View” thinking and practice within construction is lacking. Meaningful research in this space demands non-positivistic approaches able to reveal nuanced and local insights able to inform and illuminate “New View” practices and the contexts in which they could potentially be implemented on sites. Here, we make a methodological contribution with the aim to advance empirical research in this space. Social practice theory is employed and evaluated as an approach able to make such a useful contribution. Through the exploration and explication of the block of “site safety practice,” we demonstrate the utility of this theoretical approach for “New View” researchers, whilst also making a fundamental contribution to knowledge in the form of insights of the local and situated contexts, in which “New View” thinking could be practically applied.

With a rich off-site construction (OSC) experience accumulated over the last two centuries, the United Kingdom (UK) is looking up to OSC to deliver its critical infrastructure projects in the next decade. Highway projects are good fits for OSC with their project characteristics. However, the extant OSC literature for highways is mostly about OSC elements’ design performance. Also, the OSC literature is predominantly building sector focused. Addressing this gap, the paper presents the findings of a research project, sponsored by the UK’s National Highways, which aims at under-standing what needs to be done to improve the current OSC condition for highways projects in the UK from a management, technical and technological perspective. After a detailed literature review, 20 in-depth interviews with subject experts were conducted. The initial findings were vali-dated through five highways projects as cases and then ranked by two focus groups using the Delphi method. Alongside revealing the current OSC condition, 95 suggestions (43 management- related, 23 technical opportunities, and 29 technology-related) were elicited and ranked by their impact potential. Some of the high-potential suggestions are developing a collaborative OSC decision making framework, a product design mindset, improving OSC digital product libraries, creating mobile OSC factories, and a design options repository. The findings revealed that many OSC challenges identified in the general or building sector focused OSC discussions exist also in the high-ways sector. It is recommended that the identified high and medium impact potential suggestions are prioritized by practitioners and policy makers to improve the current OSC condition.

The COVID-19 pandemic has been the largest global crisis in recent decades. Apart from the countless deaths and health emergencies, the pandemic has disrupted several industries—including construction. For example, a significant number of construction projects have been interrupted, delayed, and even abandoned. In such emergencies, information gathering and dissemination are vital for effective crisis management. The role of social media platforms such as YouTube, Facebook, and Twitter, as information sources, in these contexts has received much attention. The purpose of this investigation was to evaluate if YouTube can serve as a useful source of information for the construction industry in emergency situations—such as during the early stages of the COVID-19 pandemic. The assessment was undertaken by distilling the coverage of the COVID-19 pandemic as it relates to the construction industry from the content shared via YouTube by leveraging Latent Dirichlet Allocation (LDA) topic modelling. The investigation also compared the timeline with which relevant content was shared via YouTube and peer-reviewed research articles to make relative assessments. The findings suggest that YouTube offered significant and relevant coverage across six topics that include health and safety challenges, ongoing construction operation updates, workforce-related challenges, industry operations-related guidelines and advocacy, and others. Moreover, compared to the coverage of the COVID-19 pandemic in the research literature, YouTube offered more comprehensive and timely coverage of the pandemic as it relates to the construction industry. Accordingly, industry stakeholders may leverage YouTube as a valuable and largely untapped resource to aid in combating similar emergency situations.

Industrial agglomeration (IA), a common industrial phenomenon, has been verified to have a significant impact on total factor productivity (TFP) in many industries. However, the impact of IA on TFP is seldom investigated in the construction industry, despite the existence of the industrial agglomeration phenomenon in the construction industry. As such, this study aims to probe into the impact of IA on TFP in the construction industry, so as to provide new insights into the industry development and improvement of TFP in the construction industry. Based on the competing results of the agglomeration effect and congestion effect caused by IA, this study proposed three hypotheses on the impact mechanism of IA on TFP in the construction industry. Then, the non-linear regression model and linear regression model were developed to test the hypotheses based on the provincial panel data from 2002 to 2017 in China. The empirical results reveal that IA has a positive linear impact on TFP in the construction industry, and the impact of IA on TFP in the Chinese construction industry during the observed period is in the embryonic stage. Besides, both the firm scale and economic development level have positive impacts on TFP, whereas the specialization structure has a negative impact. Hence, the government can encourage industrial agglomeration in the construction industry to enhance TFP, in order to leverage the knowledge spillovers, labor pool, and other benefits from IA.

What does “transforming” construction mean? – Where is it, who is doing the transforming, and how (and when)do we know it is happening? In ConstructionManagement and Economics and elsewhere, there is a long standing discussion amongst scholars on the topic of innovation in construction – but what of transformation in construction? Is it different, and if so – how? We set out with this Special Issue to answer these questions and advance the theoretical understanding of the transformation of the built environment, and how this requires the construction industry to transform accordingly. We believe that a “transforming construction” research agenda entails a multi-scalar perspetive and therefore called for papers on industry-level transforming, firm-level transforming, and project- and programme-level transforming. We also recognise the process focus in contemporary social science through our framing of “transforming” construction as never-ending, and by seeking out accounts of how this is unfolding in practice. This resulting Special Issue will hopefully act as a provocation for new perspectives on transforming construction: it attempts to revisit, re-evaluate, and re-invent how we conceptualise both construction and construction research. The eight papers build on a strong legacy of research on innovation in construction management, while providing new insights on what is being trans-formed and how; locating, albeit tentatively, where the future debates are; and identifying spaces where rich data may be found. Readers will find a stimulating range of conceptual thinking and empirical evidence being brought to bear on change, innovation, and transformation, with extensive discussion of implications for future research on construction policy, projects, and people, broadening our field of view and drawing out strong new ideas to guide practice.

Due to the large use of resources and waste generation, the transition to a circular economy (CE) has become a major sustainability-related topic in construction. Intentions to achieve circularity are shared widely, but developments are slow in practice. This study identifies systemic barriers to the circularity transition from a social-technical systemic perspective. We used the Mission-oriented Innovation System (MIS) framework to provide insights into the problems and potential solutions underlying the circularity mission, the structure of the system and the system dynamics. Based on the analysis of a wide range of policy documents and twenty in-depth interviews with stakeholders in the Dutch infrastructure sector, three vicious cycles were identified that form persistent barriers to the transition: (1) the CE contestation cycle given the contested nature of the circularity mission; (2) the knowledge diffusion cycle given the need to adopt and diffuse knowledge; and (3) the innovation cycle when it comes to procuring and upscaling circular innovations. These barriers all relate to processual, organizational and institutional challenges rather than to technological ones. This indicates that construction managers, policymakers and researchers in the field of infrastructure circularity should shift their focus from specific circular solutions to creating appropriate conditions for changing current and introducing novel processes that facilitate circular ways of doing things.

The purpose of the paper is to provide a method to estimate the credit risk in infrastructure public–private partnership (PPP) projects by using a structural model, the Real Options approach, and the Monte Carlo simulation technique. To do that, previous models are extended under a structural framework for credit risk where the embedded options in the credit agreement such as the option to renegotiate and the option to exit are introduced as well as the uncertainty of the cash flows. In that sense, all the components of expected loss (EL) such as the probability of default, the exposure, and the recovery rate for lenders are modelled and estimated in a PPP toll road project by considering the embedded options as well as the default events. Consequently, it is found that the embedded options improve the recovery rate for lenders and their EL. Additionally, practical insights about the effects of the embedded options in the credit agreement and the probability of default are provided.

Inter-organizational collaboration within the construction industry consists of both engineered and emerged aspects. Engineered formal practices and emerged informal practices interplay in their influence on the overall success of client-contractor collaboration. This interplay has been recognized but is still understudied and requires further research to increase the understanding of how the interplay functions. To enable the study of the emerged aspects of collaboration we applied a practice-based approach in a longitudinal multiple case study, including four projects for operation and maintenance of road infrastructure. This paper contributes to the literature on collaboration in construction by providing detailed examples of how the interplay between engineered and emerged collaboration may unfold, showing how formal and informal practices contribute to the development of vicious and virtuous cycles of collaboration. Furthermore, our findings indicate that a virtuous cycle of only informal practices can become a weakness if unexpected problems occur. Project managers should therefore be encouraged to implement formal collaboration, even if the project team is already in a virtuous cycle of informal collaboration.

Visual Management (VM) is an important Lean method to enhance information flow and reduce waste in construction. However, its adoption is hindered by several barriers. Scientific works mention that emerging technologies can support or replace conventional VM practices, but empirical evidence is missing. Based on an in-depth literature review, we derived the research questions (RQs), arguing if Augmented Reality (AR) could mitigate VM implementation barriers. Thus, a corresponding AR measurement model was developed. Through a case study of mechanical , electrical, and plumbing (MEP) installations in a multi-story apartment building, the RQs were answered using an AR head-mounted display (HMD). To gather the necessary empirical evidence, the data was collected through direct observations on-site and through semi-struc-tured interviews. The study findings show that (1) AR provided time savings and generally satisfactory accuracy levels. (2) AR demonstrably reduced the training effort to better support MEP marking work. (3) The use of AR reduced the resistance to change to adopt VM practices, although concerns were raised about poor ergonomics and work safety risks. Future research activities should consist of investigating the potential of other emerging technologies to overcome the common Lean implementation barriers in construction.

Large-scale urban development projects are complex economic and politically shaped activities, and such projects have oftentimes proved to be more costly and demanding more time to complete than is frequently being stipulated from the outset. Based on these conditions, urban development projects demand effective cross-organizational collaborations to optimize the use of available expertise, the capacity to process data and information, and to optimize public interests (being monitored by democratically elected entities in democratic societies). Based on a study of a major urban development project in Gothenburg, Sweden, this article introduces the concept of syndicated leadership, derived from the concept of syndicated investment in the venture capital industry. Syndicated leadership is based on the centralization of decision-making authority and resource allocation to a team of leaders, each representing (in the case examined) a private corporation, a municipality corporation, or a municipality agency having specific responsibilities in the shared urban development project, but also being dependent on the capacity to coordinate and align project activities. As the case indicates, syndicated leadership demands new expertise and communicative capacities and political skills, but when implemented effectively, it holds the promise of avoiding costly and embarrassing urban development project failures as it makes better use of the expertise of the participant organizations and better accommodate public interests.

Growing environmental concerns and the threat of resource scarcity have heightened interest in the Circular Economy (CE) concept over the last decade. Nonetheless, implementation of CE practice within the built environment has taken a slower pace in comparison with other industries. A clear understanding of systemic and multilevel aspects of CE, especially in relation to barriers that hinder practical implementation, appears to be lacking within the sector. In light of this, the study aims to examine the existing body of knowledge to elucidate, from a systemic perspective, CE barriers across various levels in construction. To achieve this purpose, a scientometric analysis is used to examine 581 bibliometric-searched filtered articles on CE implementation barriers in construction. Key issues, drivers and potential resolutions are explained using content analysis of specific pre-determined articles. The study finds that critical system levels of CE implementation (micro, meso, and macro levels) are interrelated. However, barriers and drivers at each individual level may differ. Additionally, this paper categorises key barriers to implementing CE-aligned strategies into five main themes, namely: definition and theory misconception, political and legislative, social and cultural, financial and economic, and technological barriers. Based on these, four cross-cutting enablers are established to drive the transition from linear to circular economy in construction. The findings of this study highlight deficiencies and challenges in current research while providing a path for future studies. It provides a convenient point of reference for practitioners, policy makers, and research and development (R&D) institutions on CE implementation within the industry. Lastly, the study raises public awareness on CE barriers and guides the AEC sector to develop intellectual capital to overcome them.

Big data application is a significant transformative driver of change in the retail, health, engineering, and advanced manufacturing sectors. Big data studies in construction are still somewhat limited, although there is increasing interest in what big data application could achieve. Through interviews with construction professionals, this paper identifies the capabilities needed in construction firms to enable the accrual of the potentially transformative benefits of big data application in construction. Based on previous studies, big data application capabilities, needed to transform construction processes, focussed on data, people, technology, and organisation. However, the findings of this research suggest a critical modification to that focus to include knowledge and the organisational environment along with people, data, and technology. The research findings show that construction firms use big data with a combination strategy to enable transformation by (a) driving an in-house data management policy to rolling-out the big data capabilities; (b) fostering collaborative capabilities with external firms for resource development, and (c) outsourcing big data services to address the capabilities deficits impacting digital transformation.

Safety management research in construction is pervasive, therefore, a systematic review and a bibliometric mapping process that provides an overview of how recent mainstream research topics are conceptually structured is timely. Undertaking systematic mapping, contemporaneous with a scoping review of construction safety management research, can contribute to a better understanding of research outcomes and predominant topics. This study employed VOSviewer as a bibliometric tool to identify co-author citations, as well as the co-occurrence of key terms within the title, abstract and keywords of the articles. A total of 180 representative studies published in 21 peer-reviewed journals between January 2010 and November 2021 were analysed. A systematic literature review identified a significant focus on conceptualizing safety climate and safety behaviour with a growing interest in applying advanced technologies for improved safety management. Two perspectives were recognized in safety research, i.e. process-driven and people-driven, with the former focussing on accident causation while the latter on underlying the active role of workers' involvement in safety outcomes. An in-depth discussion of the findings revealed seven trending research domains: safety systems; safety skills; accident caus-ation; safety leadership and communications; safety behaviour and attitude; safety climate and culture; and practices for improving safety performance. This review identified an emerging interest in seeking effective leadership styles and psychological interventions to promote safety culture and behaviour. In terms of practical implications, this study found opportunities to address the gap between theory and practice by adopting systems thinking and using IT for improving safety performance in construction projects.

Construction and infrastructure bidding is a highly competitive and complicated process that entails various uncertainties faced by contractors. The situation is more complex in multi-stage bidding (MSG) where general contractors must deal with the complexity of accounting for the bids of their subcontractors and face a greater threat of falling prey to the winner’s curse (i.e. situation where the winning contractor underestimates the actual cost of the project). Existing research efforts have tackled the issue of the winner’s curse in MSG from the general contractor’s perspective. However, there is a lack of research in developing bidding models that simultaneously aid both general contractors and subcontractors in determining their bid value to mitigate the winner’s curse in MSG. This paper fills this knowledge gap. The authors utilized an interdependent game theory (GT) and reinforcement learning (RL) approach, that includes: formulation of MSG framework; incorporation of two RL algorithms, namely the multiplicative weights and the modified Roth-Erev, to be utilized by subcontractors in preparation of their bids; utilization of MSG game-theoretic bid function for the preparation of the general contractors’ bids for the whole project; development of the MSG-GTRL model; and testing the MSG-GTRL model through simulating various bidding scenarios using a combination of actual and synthetic dataset of infrastructure projects. Results show that integrating GT and RL in MSG bidding enables general contractors and their subcontractors to simultaneously improve their financial state by minimizing the occurrence of negative earnings, and thus, avoiding the winner’s curse in their respective portions of projects.

The construction industry is facing global skills shortages, with demand for certain roles (such as project managers) projected to outstrip supply over the next decade. With the industry serving as the backbone of the economy in many countries, this projected lack of skilled construction professionals poses dire consequences. This qualitative study investigated the early career transition of project management (PM) professionals into the construction industry. Semi-structured interviews were conducted with 18 employer representatives and 20 early career professionals to ascertain the factors affecting the turnover intentions of early career PM professionals in construction. From the perspective of the early participants in this study, the major factors affecting their intentions to leave were related to workplace culture: (i) bad workplace behaviour; (ii) high levels of work-related stress; and (iii) poor work-life balance. While employers also noted that bullying and long working hours contributed to early career PM professionals’ intentions to leave the industry, they believed that the key contributing factor was that young employees were seeking higher salaries. These findings on the need to improve workplace culture have the potential to positively influence the issue of early career retention within the construction industry.

To improve the performance of construction projects, the use of relational contracting (e.g. Project Partnering, Alliancing, Early Contractor Involvement, Integrated Project Delivery) has increased among public clients in the last few decades. Despite widespread use, there are still large variations in contracting arrangements. In addition, the outcome of relational contracting remains unpredictable. The aim of this paper is to investigate how these variations may originate from internal dynamics and practices in the project-based client organisation. Adapting organisational routines as an analytical lens, the study investigates the pre-procurement routine applied to develop project-specific relational contracting models (e.g. contract schemes, reward systems, and award criteria) for large construction projects in the Swedish Transport Administration. The study contributes to research on organisational routines in project-based settings, illustrating how flexible enactment of a pre-procurement routine may balance two conflicting organisational goals: centralisation of procurement and project-level flexibility. However, while mitigating conflicting goals, the routine enactments create a variation in project-specific procurement models that hampers long-term goals of predictability and shared practices of relational contracting. Consequently, findings indicate that public clients seeking to transform contracting practices must increase their ability to develop procurement routines that can balance organisational goals and simultaneously benefit long-term goals.

The world will never be the same again, and neither will the UK construction industry. As one of the few sectors projected to bounce back rapidly from the pandemic, positive rhetoric abounds in the industry press, Government and quasi-governmental bodies about the opportunity that lies ahead to “Build Back Better”. Something else that could and more importantly should never be the same again is the health, safety and wellbeing (HSW) of the UK construction workforce. Pre-Covid-19, UK construction was neither a safe nor a healthy place to work, and transforming this situation is arguably the most important win our industry can secure from this situation. In this essay we argue that the pandemic and associated socio-economic crisis offers a unique, once-in-a-generation opportunity to bounce forward to a “new normal” of healthy, safe and hygienic construction operations, one where the worker’s psychological wellbeing shares the foreground with their physical welfare. This paradigm shift will require a radical redefinition of the matters of concern that shape construction practice, moving away from a focus on sites as the locus of production, to a focus on people. Moreover, we suggest that there is a concurrent obligation on the research community to support such a transition by using the pandemic as a new point of departure for shifting the safety discourse via more critical research approaches. These should question the axioms which currently define the ways in which projects are constituted and managed, and where production takes primacy over the workers that deliver it.

The use of industrialised construction can help meet the growing housing demand for developing economies in Africa. In order to understand future scenarios for accelerated adoption of industrialised construction, it is necessary to identify the influencing factors. To do so, this paper conducts a formative scenario analysis which is a literature- and expert-based method, focussing on three countries that have high housing demands, i.e. Ethiopia, Kenya, and South Africa. The resulting analysis consists of three parts. The first is the identification of nineteen internal and external influencing factors. These factors range from product performance to policies and regulations. The second is the illustration of the importance of each factor as a function of its relationship with the other factors. The third is the description of three possible scenarios the adoption of industrialised construction may take in the three investigated countries. The findings show that the most important accelerators for the adoption of industrialised construction come from governments’ commitment to invest in future construction and incentivize companies to adopt industrial construction methods and for these companies to produce competitive products. The specific adoption policies to be implemented, however, depend greatly on the specific situation.

Changes in public-private partnership (PPP) projects are inevitable and often lead to project failure, hence, the management of changes in PPP projects are more challenging than with traditional projects. The complex nature of changes in PPP projects, however, lacks systematic investigation and a quantitative approach in current literature. To fill this gap, this study considers the development process of major changes in PPP projects from a whole-life cycle perspective. The findings reveal significant relationships between causes and negative change results, as well as the enlarged interactive effects of certain causes. Most of the negative changes occur at the operational stage and vary across different types of project and regions, but the pre-contract stage is the most critical stage to prevent future negative changes. Hence, more proactive change management strategies are suggested for the government decision makers and project managers. This study contributes to the body of knowledge in PPP literature by providing a meta-case analysis approach, which can improve the accuracy of case selection and facilitate statistical analysis. The findings can help the researchers and practitioners to better understand the nature of changes and manage them in a more efficient way.

Previous research indicates that the success of logistics solutions in building projects depends on how they are organized in accordance with the logistics context, which is determined by building contractors’ competitive priorities, product characteristics, and production process choices. Taking a configurations approach, the purpose of this paper is to describe the fit between the logistics context and the organizing of logistics at a strategic level. A conceptual research framework is derived from literature postulating an influence of the logistics context on the organizing of logistics. The framework is applied to four cases by the means of strategic profiling, which provides a snapshot of the fit in the cases’ logistics configurations. The findings indicate that the type of production process influences the degree to which logistics decisions should be made centrally and that the degree of standardization and pre-engineering influence the degree to which logistics processes should be formalized. The main contributions are the identification of logistics configuration variables and the description of the fit between building contractors’ logistics context and the organizing of logistics. For managerial practice, a logistics configuration profiling template was developed that can be used as a tool in the logistic strategy process.

The regulatory drive to accelerate the clean energy and circular economy transitions in the European building stock is currently failing to overcome systemic implementation barriers. These barriers include high initial investment costs, misaligned financial incentives among stakeholders, and the relatively low cost of less sustainable energy and materials. A Product-Service Systems (PSS) approach could successfully overcome many of these barriers by (1) outsourcing capital investment, as well as financial and technical risks, (2) providing shared economic incentives to collaborating stakeholders, and (3) retaining extended producer responsibility and ownership over materials and products. However, PSS is still not seen as a viable business model when compared to both a standard “ownership” contract and a “no-retrofit” scenario. This paper proposes a Total Value of Ownership (TVO) method to evaluate the financial performance of a building energy retrofit in terms of Net Present Value, comparing a matrix of scenarios. Results show that – when accounting for capital and opportunity costs tied to alternative investments, internalising externalities, and monetising soft values such as user productivity and property value – a PSS model can deliver the highest NPV. Furthermore, results show that a PSS alternative can act as a positive future-proofing strategy to safeguard the building owner’s position in the face of uncertain future market indicators and carbon taxation. Recommendations for policymakers, investors, financiers, building owners, and end-users are presented to identify the economic value of PSS contracts, leading to better-informed decisions which can accelerate deep energy retrofit of the building stock.

The organization of construction in the People’s Republic of China has over recent decades undergone radical restructuring. The announcement of Deng Xiaoping’s Open Door strategy in 1978 marked the beginning of the transition towards the espoused socialist market economy and the progressive introduction of market mechanisms. Existing research tends to focus on the derivation of “critical success factors” rather than the lived realities of those directly involved. In contrast, the current paper adopts a sensemaking perspective that privileges the transient roles and identities of those involved in the micro-processes of project organizing. The empirical focus lies on the sensemaking narratives of middle managers within three state-owned construction enterprises in the Chongqing city region. The findings illustrate how market mechanisms such as bidding and tendering play out in complex ways involving hybrid arrangements between new and pre-existing ways of working. The terminology of project management is seen to have played a performative role in establishing the “project” as the essential unit around which the socialist market is organized. Middle managers are further found to maintain multiple identities in response to the experienced paradoxes of the socialist market economy. The research provides new insights into the micro-processes of project organizing in China with broader implications for transitional economies elsewhere.

Alcohol consumption is an accepted part of many social and cultural practices, but excessive alcohol consumption is a global public health concern. Aside of its detrimental effects on health, it is linked to HIV-related health behaviours such as unprotected sex, multiple/concurrent sexual partnerships, and lower levels of HIV testing. Little is known about the association between alcohol use and HIV-related heath behaviours in construction. Using data from 450 workers drawn from 18 construction sites in the Western Cape, the Alcohol Use Disorders Identification Test (AUDIT) was used to predict alcohol risk of harm as a function of demographic characteristics and sex-related behaviours among workers. Binary logistic regression determined factors associated with increased risk of alcohol harm. The most proximal factor predicting risk of alcohol harm was the frequency of alcohol or drug use before and/or during sex, followed by attitude towards condom use, education, and HIV testing behaviour. Future research efforts should develop a better appreciation of the role of sex-related alcohol expectancies in explaining harmful alcohol use, and intervention management practices should focus on this.

The slow uptake of the alternative delivery systems (ADSs) can potentially waste an astronomical amount of precious public funds that can be used to meet other critical needs (e.g., education and healthcare). The existing literature mainly focused on performance evaluation of the ADSs and few provided decision support to select ADSs matching a particular project’s characteristics or external environment. Nonetheless, there lacks of research exploring the slow diffusion of ADSs, especially a deep understanding of the interaction mechanisms of the influencing factors. This research aims to increase the use of ADSs in practice. To achieve the objective, based on the data retrieved from literature, case study, and interviews, this study, therefore, aims to: identify the internal and external influencing factors; reveal the interplays of these factors using Interpretive Structural Modeling (ISM); and analyze the driving and dependence power of the factors based on Matrice d’Impacts Croisés-Multiplication Appliquée á un Classement analysis (MICMAC). Based on the 25 identified factors, the ISM built a hierarchical structural model, which reveals the interaction mechanism of the factors and the fundamental factors. The MICMAC analysis discovered the high driving, high dependent, transitive/linkage, and independent factors on the diffusion of ADSs. The findings contribute to the body of knowledge about what and how the factors influencing the slow diffusion of ADSs and help contractor administrators formulate effective strategies to improve the usage of ADSs.

Blockchain represents an evolving technology for distributed and secure recording and sharing of information. Meanwhile, blockchain has thrived in banking, finance, and supply chain; its usage within the construction industry is still in its infancy. To this end, the existing literature falls short in providing comprehensive quantitative understanding, within a systems-based analytic context, of the factors affecting blockchain utilization in construction applications. This paper fills this knowledge gap. The authors: (1) conducted an extensive literature review on blockchain implementation in the construction domain; (2) identified a list of 41 factors affecting blockchain implementation in construction projects categorized in four categories: challenges, needs, requirements, and capabilities; (3) utilized a social network analysis (SNA) approach on a database of 111 publications to quantitatively analyze the literature as related to the aforementioned factors; and (4) performed clustering analysis on the SNA graphs to determine the combinations of factors that are most likely co-occurring in research publications. SNA results indicate that while the most investigated factor was “increased trust and transparency between project parties”, the least studied factors included: “cash upfront funding system”, “change payment processes and procedures”, “smart contracts design errors”, “cryptocurrency fluctuations”, “lack of sufficiently skilled personnel”, and “increased awareness and capabilities of personnel”. Also, clustering outcomes highlight that some combinations of factors are not well-represented in current scholarly efforts. Such imbalance and consequent knowledge gaps may contribute to the actual implementation rate of blockchain in construction applications. Ultimately, this paper provides a roadmap for potential future directions of blockchain construction-related research.

Several efforts for industrializing construction have been made in different countries, and there has been a growing demand for engineer-to-order (ETO) industrialized building systems. In this context, products are unique for specific clients, as customer orders are placed at the design stage. There are many challenges for planning and controlling those building systems, due to the high level of complexity involved. The aim of this research is to propose a set of core requirements for production planning and control systems in ETO industrialized building systems. The methodological approach adopted in this investigation was design science research. It was based on a literature review on different planning and control models, and also on an empirical study carried out in a steel fabricator company. The proposed set of requirements is aligned with the management-as-organizing approach, challenging some traditional project management assumptions, including the use of metrics and practices that are not suitable for the high degree of complexity that exists in ETO environments. As a practical contribution, the requirements can be used by ETO construction supplier companies to support the conception and development of planning and control systems.

Public facilities management (PFM) is currently moving from being an institution driven by ad-hoc practices to now introducing long-term and strategic practices. During this institutional change, human actors engage in institutional work to create new practices. However, old practices seem to be maintained within PFM to a large extend. Why? Data were collected through case studies in two public facilities management organizations, an interview study in eight organizations from the institution of PFM and a workshop with representatives from the institutional field of PFM. Findings show how the changing institutional setting for the institution of PFM produce negative emotions. To manage these, human actors engage in institutional work and here they employ artefacts as means to drive change. These artefacts functioned in various ways to reduce negative feelings by inducing a sense of safety (as soft blankets), by enabling the avoidance of dealing with ‘the truth’ (as shields) and by offering hope (as a vision of perfect future). Thereby, they did not take part in creating change, as much as they took part in maintaining current practices. The unintended consequences of the usage of artefacts, explain why practices are maintained during institutional change for PFM. © 2022 The Author(s).

Transactional and transformational safety leadership have been repeatedly found to be important for safety. Yet how transactional and transformational leadership behaviours are most effectively demonstrated can be dependent on the context and industry. Using an ethnographic approach, supervisor safety leadership was explored across eleven construction sites in Australia. The findings revealed that, within the construction site context, contingent reward, idealised influence, and management-by-exception behaviours demonstrated by supervisors closely aligned with their definitions in Full-Range Leadership Theory (FRLT). These three types of leadership behaviour reflect observation of supervisors’ positive actions, which included: praising workers for good safety performance; proactively anticipating and attending to safety issues; and consistently leading-by-example with safety, even at times of significant production pressure. Other theoretically described dimensions of leadership behaviour, i.e. individual consideration, inspirational motivation, and intellectual stimulation, were not directly reflected in observed supervisors’ behaviour in the way they are conceptualised in FRLT. The existence of a good supervisor-worker relationship enabled workers to comfortably raise safety issues, think creatively about how to undertake work safely, and talk to their supervisor if they were experiencing personal problems. These are motivational, intellectual, and empathetic elements of leadership, which do not directly align with the way leadership behaviours are conceptualised in mainstream FRLT. The study suggests that, in the construction worksite context, leadership behaviours may take a form that differs from theoretical ideal types and that ethnographically attained insights into supervisors’ interactions with workers can contribute to understanding transformational and transactional leadership in practical terms.

Collaborative scheduling (CS) and related practices impact the performance of construction projects which can be measured by key performance indicators (KPIs). However, little is known about which of these practices are implemented and how their combined implementation might impact KPIs. The objectives of this research are to identify perceptions of CS practices that drive project performance, define CS practices used by industry that impact KPIs, and establish practices that are more commonly implemented and have a higher potential to positively impact KPIs. The research team conducted a nationwide survey in the United States and obtained 241 usable responses. Utilizing an information theory approach to measure the uncertainty of implementation and impact of each practice, the research built a set of Chow–Liu tree models to determine the most efficient sequence of actions to improve CS. Results indicate that meeting owners’ expectation throughout the life-cycle of the project from design through construction and commissioning, using the schedule to support a strong project culture, and an effective communication plan were the top CS levers for overall KPI improvement. An innovative method was developed to help construction project managers discover the value of each CS practice, the relation between CS practices, and CS practices’ influence to project KPIs so that managers can improve KPIs efficiently by prioritizing their CS practices according to their own project needs.

Ethnography offers a route to knowing about the everyday activities of construction workers, but its long duration is not always suited to the site environment or the researcher’s resources and the workers themselves are constantly changing. Short-term ethnography is an alternative to the traditional format that permits a shorter length of fieldwork activity in return for intense engagement between the researcher and their participants. The rich points that make up an ethnographic account need to be actively sought in short-term ethnography. This can be achieved by utilizing the prior construction experiences of the researcher. The researcher enters the field with an emic insight that can be used to seek out events and allows the production of meaningful ethnography from a shorter, more intense fieldwork period, learning much from individual workers before they move on. Engagement extends beyond the onsite interactions through the use of video cameras to record everyday activities. Examples from two short-term ethnographies of two deliberately different sites explain how, in the search for craft traits among construction workers, the fieldworker is able to mobilize emic insight and craft theory to seek out rich points in everyday events which are typically serendipitous in nature. This account serves to provide a demonstration of how the very real tensions between the limitations of project context as a field site and the need for methodological rigour can be reconciled through careful attention to reflexive ethnographic practice. © 2018 The Author(s).

The need for building renovation is receiving increased attention in many countries around the world. One reason for this is an ageing building stock. Another reason is the urgent need to reduce energy consumption and greenhouse gas emissions in buildings. The UNFCCC Paris Agreement at COP 21 in 2015 agreed on limitation of the global temperature increase to 1.5 °C above pre-industrial levels by 2050. This requires a fast transition to renewable and fossil free energy. Reaching the goal won’t be feasible without reducing the energy demand where possible and this also applies to buildings. Globally, the building sector accounts for approximately 28% of total energy-related CO2 emissions (IEA 2019). Therefore, a major contribution to achieving emissions reductions must come from renovation of the existing stock to increase insulation and changing the building services (heat, cold, ventilation, electricity) to carbon free systems. Insights in the energy efficiency of residential buildings in Europe and the monitoring of the progress of renovation can be found in a special issue of Energy and Buildings (Visscher et al. 2016). The rate of renovation needs to speed up and the renovations should be deeper (IEA 2019). Deep renovation is addressed further on in this article. Central and local governments all over the world are translating the carbon reduction goals to policies and action plans for retrofitting the existing building stocks. As a concrete example, the European Commission presented October 2020 an integrated policy and support action “A Renovation Wave for Europe - greening our buildings, creating jobs, improving lives” (EC 2020). The plan describes the high aimed goals and huge challenges and barriers to overcome for the European building stock. It makes clear that research and innovation will be needed to overcome the barriers. (Wade & Visscher 2021) There is at the same time a need to upgrade many buildings to improve the quality of life – social sustainability, and to increase productivity in the building process to ensure affordable housing – economic sustainability. Research in Sustainable Building Renovation (SBR) has also increased. An editorial article by the first guest editor of this special issue included a proposal for a research agenda for SBR based on a review article (Jensen et al. 2017, 2018). The identified research gaps and needs for new research are summarized below. This special issue of Construction Management and Economics aimed at publishing new research which contributes to or supplement this research agenda. The barriers for SBR have been studied broadly and the drivers for SBR are also quite well researched. The barriers can be divided in economic and informational aspects. Among the economic barriers is the landlord/tenant’s dilemma (Ástmarsson et al. 2013). Building renovation is mainly initiated because there is an accumulated backlog of maintenance and degraded/outdated building components. Thus, to promote sustainable renovation including energy improvements, financial incentives are important drivers, but it is also important to take various stakeholders’ different interests into account. There is a need to develop new instruments to increase the volume of SBR and methods to evaluate such instruments. The focus of most research on building renovation has so far been on deep renovation. Deep Renovation or Deep Energy Renovation is a term for a renovation that captures the full economic energy efficiency potential of improvement works, with a main focus on the building shell, of existing buildings that leads to a very high-energy performance (Global Buildings Performance Network 2013). Such renovations are encouraged in European energy policies (EU 2016, EC 2020). A main argument for deep renovations is that they are a necessity to achieve radical improvements in energy efficiency. However, recent research in Sweden has observed a trend of housing associations moving towards applying partial or over-time renovation strategies (Femenías et al. 2018). There is a need for research on the diversity of current and potential new strategies for SBR including renovation over time (Fawsett 2014), and of both singular building projects, portfolios of buildings and districts. The renovation process has been studied in several research papers, but mostly in terms of case studies and dominated by preconceptions of rational decision-making and development of normative guidelines. There are only few examples of broader cross-sectional research studies investigating specific aspects of renovation processes among a larger sample of projects, companies, professionals and/or countries. One example is the study by Gluch et al. (2018). There is a need for more in-depth descriptive and cross-sectional studies of SBR processes in practice to reach a deeper understanding of the different sub-processes of renovation, for instance collection of data on buildings before renovation, the actual use of tools in different renovation sub-processes, the characteristics of processes for different building types and organizations. The organization of SBR projects has only been researched to a very limited degree and there have been limited attempts in practice to develop new forms of organization of SBR. Outside of building renovation, there have been recent studies that examine new form of cross-sectoral collaborations to drive social value through construction projects (e.g. Barraket and Loosemore 2018). There is thus scope to draw inspiration from these studies to feature research that can support increasing the performance of SBR, for instance, by improved collaboration across the value chain and across sectors with more learning across projects and companies. The application of relational contracting seems a promising direction for further development of building renovation. There have been intensive research and development of tools and systems to support decision-making, design and evaluation of SBR projects (see e.g. Mjörnell et al. 2014, Malmgren and Mjörnell 2015, Malmgren et al. 2016), but only few with a focus on portfolios of projects. Exceptions are Nielsen et al. (2018), Österbring et al. (2019) and Nägeli et al. (2019). Moreover, the methods for evaluation of social sustainability are underdeveloped, as well as consideration for architectural and historic values (Thuvander et al. 2012), and there is a lack of integration of evaluating the different pillars of sustainability. Only a few attempts to integrate different values can be found, as in Serrano-Jiménez et al. (2021). There is a need to develop more holistic methods for prioritising and evaluating SBR. While there has been a stronger technological emphasis in previous studies on SBR, there is growing interest in taking into account the perspectives of building users (see e.g. Mangold et al. 2016, Buser and Carlsson 2017, Tjørring and Gausset 2019). This more social viewpoint is critical as there is a need for more research that can support a pull from the demand side, including building owners, facilities managers and end-users to disclose and drive unfulfilled needs and new opportunities. The increased political focus on SBR makes it important to investigate and demonstrate the contribution that SBR can have in relation to solving important societal challenges, for instance, in relation to UN’s Sustainable Development Goals, climate change, energy transition, circularity, industrialization, digital transformation, affordable housing provision and equality, heritage preservation, social value and quality of life.

The nature of the construction industry is different from other sectors due to the unique and temporary nature of projects which makes incremental improvements difficult necessitating the need to understand the practice of innovation. This research aims to explore the role of narratives in shaping innovation, as these provide a way to manage the tensions prevalent in the industry. We study 133 innovations across different construction projects in the UK and seek to understand the role of narratives in motivating these innovations. For instance, “innovations that enable project completion,” “innovations that improve productivity,” “innovations in health and safety” and “innovations in sustainability” are discussed. Whilst we acknowledge that factors such as incentives and rewards can motivate innovation, we argue that narratives shape or guide innovation in a particular direction. Since construction projects are interorganizational and multileveled, the industry-level narratives need to be adopted by firms to enable innovations at project sites. Innovators actively look for areas where they can intervene, and narratives improve the visibility of some areas thereby guiding innovations to them.
