Construction research comprises quality contributions to the modern methods of construction (MMC) context in terms of their benefits and relative advantages. However, the uptake of MMC is yet deemed very low in the public sector. Knowing that public clients acquire the purchasing power and the influential status to drive industry change, understanding their low MMC uptake is necessary.

A systematic review of literature has been chosen to extract the key variables contributing to the limited adoption of MMC across the public sector, reinforced by a qualitative semi-structured interview with 12 industry leaders and public clients. This methodology enables the authors to explore works from the past decade, paving a direction for an adequate empirical investigation by reviewing and critically analysing 49 academic articles and interviewing 12 industry leaders and public clients.

The study captured and argued the characteristics that have an influence on public clients' decision, inhibiting the extraction of values associated with greater MMC deployment. A critical analysis resulted in identifying 13 characteristics under 4 main themes, providing a new argument to existing knowledge by calling on the need to better understand public clients and the influence of their own characteristics on their MMC uptake.

This paper utilises the diffusion of innovation (DOI) theory which offers constructs that help explain the influence of the characteristics of a decision-making unit. The authors’ knowledge on public construction clients is limited, and more research in this direction may help in better aggregating construction demand. Overall, arguments provided in this paper enable relative improvements in supply's business models when approaching the public market. The study is believed to be in support of the relative governmental efforts to shape effective policies that can enhance innovation uptake among public bodies.

The recent failures and insolvencies of organisations related to the modern methods of construction (MMC) have gained increased attention and controversy across the UK construction sector. Such failures are linked to their inability to achieve an economy of scale and drive key clients to accept the MMC as an alternative to traditional methods. This paper aims to unravel whether a phenomenon of “innovation negativism” has manifested and is contributing to public clients' indecision towards broader MMC, whether this is only linked to past negative experiences formed after the Second World War or whether additional contributing reasons exist to influence adoption.

This study focusses on exploring the decision-making of the UK public construction sector; therefore, this paper adopts a qualitative approach, utilising interviews with 14 carefully selected MMC experts, government advisors and public clients. The phenomenological stance adopted herewith enables the authors to make better sense of the perceptions of the interviewees, leading to the conceptualisation of the innovation negativism phenomenon.

The paper identifies nine themes that may be argued to promote a profound understanding of the MMC negativism influencing public clients' decision-making. The study has found that more than just the previous negative perceptions formulated post Second World War are driving innovation negativism in the UK public sector. Notably, the emerging themes are incomprehension, lacking evidence, communication, relationship history, bad experiences, uncertainty, inadequate experimentation, the business case and localism.

This study is the first construction management research that acts as a fair departure point to conceptualise the reasoning behind innovation negativism in the construction setting. Through mirroring demand's unipolarity for traditional methods, policy and decision-makers can now rely on the conceptualised reasoning to determine practical solutions to overcome clients' indecisions towards MMC.

The coheating test is the standard method of measuring the heat loss coefficient of a building, but to be useful the test requires careful and thoughtful execution. Testing should take place in the context of additional investigations in order to achieve a good understanding of the building and a qualitative and (if possible) quantitative understanding of the reasons for any performance shortfall. The paper aims to discuss these issues.

Leeds Metropolitan University has more than 20 years of experience in coheating testing. This experience is drawn upon to discuss practical factors which can affect the outcome, together with supporting tests and investigations which are often necessary in order to fully understand the results.

If testing is approached using coheating as part of a suite of investigations, a much deeper understanding of the test building results. In some cases it is possible to identify and quantify the contributions of different factors which result in an overall performance shortfall.

Although it is not practicable to use a fully investigative approach for large scale routine quality assurance, it is extremely useful for purposes such as validating other testing procedures, in-depth study of prototypes or detailed investigations where problems are known to exist.

Successful building performance testing is a vital tool to achieve energy saving targets.

The approach discussed clarifies some of the technical pitfalls which may be encountered in the execution of coheating tests and points to ways in which the maximum value can be extracted from the test period, leading to a meaningful analysis of the building's overall thermal performance.

The purpose of this paper is to identify the impact of traditionally unmonitored energy sources and sinks on assessment of the as-built thermal performance of occupied homes. The analysis aims to demonstrate the potential scale of uncertainties introduced in a heat balance estimation of the heat transfer coefficient (HTC) when using in-use monitored data.

Energy flows for two UK homes – one a 1930s dwelling with high heat loss, the second a higher-performing 2014-built home – are predicted using the UK Government’s standard assessment procedure (SAP) and visualised using Sankey diagrams. Selected modelled energy flows are used as inputs in a quasi-steady state heat balance to calculate in-use HTCs as if from measured data sets gathered in occupied homes. The estimated in-use HTCs are compared against SAP-calculated values to illustrate the impact of including or omitting various heat sources and sinks.

The results demonstrate that for dwellings with low heat loss, the increased proportion of heating demand met by unmetered internal and solar gains informs a greater sensitivity of a heat balance estimation of the HTC to their omission. While simple quasi-steady state heat balance methods may be appropriate for dwellings with very high heat loss, alternative approaches are likely to be required for those with lower heat loss.

A need to understand the impacts of unmetered heat flows on the accuracy with which a building’s thermal performance may be inferred from in-use monitored data is identified: this paper illustrates the scale of these impacts for two homes at opposite ends of the energy performance scale.

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.

Various studies have been conducted to explore the factors that are important to be considered for the effectiveness of construction contract administration (CCA) but lack in the context of graduate architects. The purpose of this study is to identify factors influencing the effectiveness of graduate architects in CCA and possible methods to enhance their work efficiency through developing the relevant skills in a changing construction environment.

This paper identified the factors that influence the effectiveness of graduate architects in CCA through the quantitative methods. General skill elements that are perceived as essential for the effectiveness of CCA had been investigated through a survey of graduate architects in the construction industry. One hundred and twenty-seven completed questionnaires returned were analyzed and tested using descriptive analysis and relative important index (RII).

The result from the study showed that the factors influencing the effectiveness of graduate architects as CCA are building construction skills, design management skills, project management skills, soft skills and dispute resolution skills.

The contribution of this study can be utilized for developing models/tools in the future that would improve the work performance of graduate architects in CCA. Educators may utilize this study to improve their syllabus to cater to the market's demand and facilitate students' entry into the labor market.

The purpose of this paper is to report on partial findings of a research project on post‐occupancy design in school projects. It provides a brief review of key factors, and major players in post‐occupancy processes.

Subsequent to literature review for the research, the primary data was obtained from a steering group (stakeholder forum) comprising of a sample of primary and secondary school representatives, local authorities and building professionals. Following the data collection, visits were arranged to the selected schools, and local councils and semi‐structured interviews with school and council authorities were carried out. At the same time, research meeting and directed studies were held to best explore the applications for devising the toolkit. Simulated and real cases for making decisions in post‐occupancy design were selected to devise a model‐base to test out the applicability of the devised prototype of the toolkit.

This study provided clarification on the post‐occupancy performance and practicable expectations of major parties in school projects with special reference to the development stage of the proposed toolkit. The qualitative and quantitative data collected, confirmed that a real‐time updateable support system for decisions is required for making the most reasonable decisions where multi‐criteria/multi‐agent decision is inevitable. The principles of co‐creation of knowledge and value, as suggested in manufacture and service industries, were investigated to inform the underlying design platform for the toolkit. The decision support systems for multi‐criteria decision making processes were also established so that the toolkit can take a full account of the achievements in this area.

The paper highlights the complexities involved in the post‐occupancy decision processes in school projects. Also, the pressing need for a system to assist in streamlining the information flow (particularly upwards, from the schools to the LA) and management of knowledge to facilitate design decisions is identified. The decision processes need to be more integrated, collaborative and inclusive. It also acknowledges that decision making in post‐occupancy processes, is an evolving process. The main contribution of this paper however, remains to be how the collaborative processes were streamlined for all the stakeholders to work together and co‐create knowledge and value to devise a platform.
