This paper presents the results from interviews of 59 senior personnel from major construction clients. There are two main themes: client drivers for construction projects and their implications for standardization of processes and components. The client sample is described and reasons for procuring construction projects are established along with the extent of their involvement in the construction process and hence their ability to influence the outcomes. Their views on value for money, preconceptions of standardization and their opinion on its future potential are explored. Many clients recognize the need to involve constructors and manufacturers early, although fewer actually achieve this. Misconceptions about standardization exist, but many clients are recognizing the benefits possible from standardization. However, very few actually measure benefits and so are unable to truly evaluate success. There is a future for increased standardization, but only if the industry recognizes the unique aspects of each client and responds positively to meet those needs.

This paper presents tools and equipment aspects of the results from a three‐year United Kingdom Government funded research project investigating accident causality (ConCA). The project has used focus groups and studied in detail 100 construction accidents site audits, interviews with involved persons and follow‐up along the causal chain. This paper concentrates on the influence of construction tools and equipment which were found to be important contributory factors identified by the research. They have largely been overlooked by previous studies and are not typically acknowledged as accident contributors. This paper argues for further work to confirm these links and for the inclusion of tools and equipment in the list of categories in statutory reporting procedures. This would also require an increased acknowledgement by construction managers of their influence, leading to better design and management of their supply and care on site.

With numerous and ambiguous sets of information and often conflicting requirements, construction management is a complex process involving much uncertainty. Decision makers may be challenged with satisfying multiple criteria using vague information. Fuzzy multi-criteria decision-making (FMCDM) provides an innovative approach for addressing complex problems featuring diverse decision makers’ interests, conflicting objectives and numerous but uncertain bits of information. FMCDM has therefore been widely applied in construction management. With the increase in information complexity, extensions of fuzzy set (FS) theory have been generated and adopted to improve its capacity to address this complexity. Examples include hesitant FSs (HFSs), intuitionistic FSs (IFSs) and type-2 FSs (T2FSs). This chapter introduces commonly used FMCDM methods, examines their applications in construction management and discusses trends in future research and application. The chapter first introduces the MCDM process as well as FS theory and its three main extensions, namely, HFSs, IFSs and T2FSs. The chapter then explores the linkage between FS theory and its extensions and MCDM approaches. In total, 17 FMCDM methods are reviewed and two FMCDM methods (i.e. T2FS-TOPSIS and T2FS-PROMETHEE) are further improved based on the literature. These 19 FMCDM methods with their corresponding applications in construction management are discussed in a systematic manner. This review and development of FS theory and its extensions should help both researchers and practitioners better understand and handle information uncertainty in complex decision problems.

Substantial changes were made on many UK construction projects in response to the COVID-19 pandemic. The purpose of this paper is to explore the unanticipated positive consequences of these and the scope for longer-term learning and developments within the sector.

A qualitative approach was used, semi-structured interviews were conducted across six major project sites. Interviewees (n = 33) included site and senior managers, supply chain representatives and occupational safety and health (OSH) professionals. The interviews explored their experiences of working on site during the pandemic, the changes made to work practices and their perceived impacts of these changes.

Improved planning and work sequencing were part of the revised process to make sites COVID-secure. This increased worker effectiveness and housekeeping/tidiness. The view on some sites was that this would improve OSH performance. The changes were perceived to be beneficial but may not be accepted by clients in the long term, as they could result in projects taking longer to complete. The ways in which COVID-19 risk has been communicated and perceived also provides longer-term lessons for the sector’s OSH management and training.

Construction has adapted rapidly and effectively to new ways of working during the pandemic. This research captured in real time some of the changes made and presents an argument for embedding and adopting the changes to improve working arrangements and OSH within the construction sector.

Decisions made during the design stage of construction works can significantly reduce the risk of occurrence of occupational accidents, injuries and illnesses. Moreover, it has been established that design is one of the major contributors of accidents and injuries. Design for safety (DfS) studies within construction have highlighted factors affecting the implementation of DfS, among which are designer attitude; DfS knowledge/awareness and education; availability of DfS tools, including guidance; client’s influence and motivation; and legislation. The purpose of this study is to carry out an in-depth literature review of DfS studies within construction to explore the extent to which existing DfS research has looked at the above-listed DfS implementation factors.

A review of 164 journal articles related to DfS in construction (published from 1990 to 2017) within built environment, engineering and multidisciplinary safety journals was undertaken.

The findings indicate that around 60 per cent of the journal articles reviewed address designer knowledge/awareness and education issues, about 27 per cent looked at DfS implementation tools to assist designers to undertake DfS, about 23 per cent studied client influence/motivation, about 16 per cent studied designers’ attitudes towards DfS implementation and approximately 16 per cent looked at the role of legislation in DfS implementation. The literature points that client influence/motivation and legislation are very influential DfS implementation factors despite a limited number of studies in these areas.

Overall, the findings provide an indication of areas of DfS implementation, particularly client influence/motivation and legislation, where more research would be needed to promote DfS in construction to help mitigate the occurrence of accidents and injuries.

This study aims to develop a more inclusive working definition and a formalised classification system for offsite construction to enable common basis of evaluation and communication. Offsite manufacturing (OSM) is continuously getting recognised as a way to increase efficiency and boost productivity of the construction industry in many countries. However, the knowledge of OSM varies across different countries, construction practices and individual experts thus resulting into major misconceptions. The lack of consensus of what OSM is and what constitutes its methods creates a lot of misunderstanding across Architecture Engineering and Construction (AEC) industry professionals, therefore, inhibiting a global view and understanding for multicultural collaboration. Therefore, there is a need to revisit these issues with the aim to develop a deep understanding of the concepts and ascertain what is deemed inclusive or exclusive.

A state-of-the-art review and analysis of literature on OSM was conducted to observe trends in OSM definitions and classifications. The paper identifies gaps in existing methods and proposes a future direction.

Findings suggest that classifications are mostly aimed towards a particular purpose and existing classification system are not robust enough to cover all aspects. Therefore, there is need to extend these classification systems to be fit for various purposes.

This paper contributes to the body of literature on offsite concepts, definition and classification, and provides knowledge on the broader context on the fundamentals of OSM.

As part of the UK Government’s strategy to address the current shortage of primary school places is the construction of standardised designed schools. The UK Government has been facing an uphill battle to meet the demand for the ever-increasing number of school places it requires. This paper aims to explore the use of standardised school design in addressing the problem of primary school places in the UK.

Due to the exploratory nature of this investigation, a pragmatic research philosophy is utilised and mixed-method data collection techniques are used. Quantitative data collection is in the form of a survey involving 306 construction professionals and stakeholders; this has been consolidated using qualitative data collection in the form of nine purposefully selected semi-structured interviews.

The research highlighted the influence that people and their perceptions have on the successful implementation of standardisation. The results show that a high level of misunderstanding exists around the concept of standardisation and its definition. Standardised design has shown to have a remarkable influence in reducing the cost and time required for delivering the construction of new schools.

Due to the exploratory nature of this research, the results obtained have not been wholly conclusive but have instead provided a contribution to the area of standardisation in construction.

The research has uncovered that, to truly promote and drive standardisation in the delivery of schools, a joint approach is required with designers, contractors, clients and manufacturers, working in partnership to develop successful solutions. The paper will, therefore, help the key stakeholders delivering standardised schools in UK to fully understand the concept and turn the challenges into opportunities.

This chapter discusses the profound and influential impact the construction industry has on the national economy, together with the huge negative effect it has on the environment. It argues that by adopting smart and industrialised prefabrication (SAIP), the Australian construction industry, and the construction industry globally, is well positioned to leverage the circular economy to advance future industries with less impact on our natural environment. It discusses aspects of the application of digital technologies, specifically building information modelling, virtualisation, augmented and virtual reality and 3D printing, coupled with reverse logistics as a proponent for advancing the circular economy through smart, digitally enabled, industrialised prefabrication. It further postulates a framework for SAIP for the circular economy.

Against the backdrop of the contribution of design to the occurrence of occupational injuries and illnesses in construction, design for occupational safety and health (DfOSH) is increasingly becoming prominent in the construction sector. To ensure that design interventions are safe for construction workers to build and maintain, design firms need to have the appropriate organisational capability in respect of DfOSH. However, empirical insight regarding the attributes that constitute DfOSH organisational capability is lacking. The purpose of this paper, which trailblases the subject of DfOSH organisational capability in construction, is to address two key questions: what organisational attributes determine DfOSH capability? What is the relative priority of the capability attributes?

The study employed three iterations of expert focus group discussion and a subsequent three-round Delphi technique accompanied by the application of voting analytic hierarchy process.

The study revealed 18 capability attributes nested within six categories, namely: competence (the competence of organisation’s design staff); strategy (the consideration of DfOSH in organisation’s vision as well as the top management commitment); corporate experience (organisation’s experience in implementing DfOSH on projects); systems (systems, processes and procedures required for implementing DfOSH); infrastructure (physical, and information and communication technology resources); and collaboration (inter- and intra-organisational collaboration to implement DfOSH on projects). Whilst these categories and their nested attributes carry varying weights of importance, collectively, the competence-related attributes are the most important, followed by strategy.

The findings should enable design firms and other key industry stakeholders (such as the clients who appoint them) to understand designers’ DfOSH capability better. Additionally, design firms should be able to prioritise efforts/investment to enhance their DfOSH capability.

This paper aims to identify and discuss how process and people factors influence the successful implementation of organisational interface management in offsite bathroom construction.

A literature review identified 16 process and people factors. A mixed method approach was used to analyse data from eight offsite bathroom case study projects. A ranking approach determined the main process and people factors, consequently analysed using (Minitab) Frequency analysis, the Wilcoxon Signed Rank test and thematic analysis to establish the contributing sub-factors and their inter-relationships, to each other and to the literature. These factors and sub-factors formed the final conceptual model, bringing together interface management and offsite bathroom construction.

The nine factors instrumental to the conceptual model include six process factors: procurement, design management, supply chain management, health and safety, tolerance and quality and three people factors: communication, client/design team and project manager, reflecting the construction industry focus on hard processes over soft. The role of the project manager and communication, however, are the main factors which contribute to overall project success. Direct management of the offsite works by the contractor’s project manager is also highly significant.

Limitations include the (UK) geographical focus of the research and the focus on bathroom pods in buildings.

The research recognises three people (social) factors: communication, client/design team and project manager, with the first and third being the main factors which contribute to overall project success.

Originality stems from the focus on organisational interface management and how this relates to offsite bathroom construction (a practice gaining considerable momentum in industry) and the resultant model. Being grounded on more than one body of academic literature as well as 8 case studies and 82 industry interviews, there is value to both researchers and construction industry practitioners alike.
