Set-based design (SBD) is a lean tool widely adopted for improving design processes and providing value maximization to clients. The purpose of this paper is to present the development and testing of a lean simulation game that incorporated point-based and SBD principles. The objective of the game was to enhance learning of lean design management among construction students.

After a thorough and comprehensive literature review consisting of secondary data in journal papers, books, thesis references and primary data in the form of interviews with lean practitioners, the simulation game prototype was developed. The testing of the game was carried out with a study group. Data were collected during the gameplay with the help of a questionnaire survey on a confidence scale and Likert scale and assessed using the Wilcoxon signed-rank test, histogram, one-sample t-test and false discovery rate (Benjamini–Hochberg) correction method.

The data collected both pre- and post-simulation showed an increase in average confidence in understanding from 3.33 to 3.89, a 16.7% rise. The data was further interpreted by using Wilcoxon signed-rank test, indicating that the post-simulation learning experience was significantly better than the pre-simulation one. Promising positive results were obtained for the questions on game design, engagement and understanding of point-based design and SBD concepts.

The simulation game helps bridge the gap between knowledge building and real-life by effectively imitating the process. The game facilitates a dynamic and critical approach toward developing new educational simulation games and their successful incorporation in propagating lean principles in the construction industry.

The effect of the chosen procurement model on the contractual performance is an important but less researched area in governance literature. Therefore, the aim is to study the ramifications of procurement options on the contractual hazards emanating due to information asymmetry.

Four Indian MSW case studies provided the necessary evidence for the present study. Cross case analysis was conducted from the perspectives of information asymmetry, contract management skills of urban local bodies (ULBs), and uncertainty.

The findings suggest that bundling of MSW supply chain would increase the uncertainty of the project, and that contract management skills have a detrimental effect but more in a bundled project. Accordingly, occurrences of information asymmetry and related contractual hazards are more in bundled projects.

The present understanding of the ULBs is not realistic enough to consider the full complexity of the strategic interactions between agents who are privately informed in an ill-developed institutional setting of the MSW sector. The current study will help untangle these complexities in keeping with the procurement model. Thereby the ULBs can focus on the steps required to address the residual uncertainties.

Limitations concerning generalizability of the findings to other projects, sectors, and geographical settings apply to this study.

This study provides significant practical directions on the sources of information asymmetry and its relation to the chosen procurement model, which is ignored thus far by the researchers and practitioners.

The recent surge in light emitting diode (LED) lighting retrofitted into schools in the UK is as a result of the UK Government’s 2050 zero carbon pledge. However, the benefits and consequences of LED retrofit projects for staff and enablers and stakeholder knowledge gaps about LED lighting retrofitting have not been fully explored. The aim of this research is to determine the amount of savings in cost, carbon reduction and kilowatt usage and to confirm if repayment from energy and cost savings derived from LED retrofit school projects funded through the SALIX funding option in the UK would be enough to service the loan. Thus, it examines monetary and non-monetary benefits, internal project stakeholder knowledge gaps and the consequences of LED retrofit for the staff and enablers of a large community college in the UK which is funded through the SALIX funding option.

The methodology relied on a hybrid research approach of a case secondary school through the review of literature, analysis of secondary data, focus group and questionnaire survey. The focus group consists of six key project stakeholders. The secondary data was sourced from the Project IGP [Individual Grade Proposal] and the Positive Energy Report from Zenergi, and the closed online questionnaire survey was used to sample 150 teaching staff and school enablers.

The findings show that stakeholders lack project knowledge, trust and expertise/project comprehension. This is in terms of baseline information, LED technology/management, payback modalities, management of risks and ethical issues around environmental impact. The forecasted SALIX savings were not achieved in real-time, partly because it does not take into consideration the increase in energy costs over the payback period. However, the LED retrofit creates efficiencies; drives down energy costs and energy usage; and drives carbon reduction, helping pupils’ learning, improving productivity and performance, and finally leading to a better lighting environment for the school community.

The study will help schools in the UK that intend to access SALIX finance for LED retrofits to understand the challenges and mitigate the risks. It will also help the government to understand the importance of adjusting the payback modalities to the base price when the retrofit was carried out for real-time savings to be made. The research would be useful in ensuring the proactive involvement of all the identified stakeholders in understanding the challenges and what the function entails.

Megaprojects have a long-lasting impact on all three dimensions of sustainability-social, environmental and economic. The advent of the COVID-19 pandemic has further heightened the importance of sustainability due to its disastrous consequences on the global economy and business activities. This study aims to explore the interactions and interventions of various actors in the megaproject field to institutionalise sustainability.

The current study adopted the organisational field approach as the theoretical lens to understand the decision-making process amongst multiple actors with conflicting interests that come together to play an active role in addressing a common interest of sustainability in megaprojects. A single case study has been undertaken using an Indian metro rail megaproject with multiple sources of data (interviews, documents, media reports).

This study showed that the institutionalisation of sustainability is dependent on interactions of various organisations and influences from institutions. Various institutional measures organised within the field to enhance sustainability practices before and during the COVID-19 pandemic are captured. Four institutional logics (instrumental, intrinsic, equivocal and political) that emerged from the case study are discussed. Finally, while not exhaustive, this study proposed recommendations that can help refine sustainability actions considering COVID-19 implications on megaprojects.

This study's findings emerged from a single case study. The developed conceptual framework can help further research with multiple cases of megaprojects in various fields or countries.

This study would be novel in advancing the organisational field approach in megaproject sustainability.

The weak competencies in urban local bodies (ULBs) for implementing public private partnership (PPP) projects are recognized as a major hurdle in uptake of the PPP model in India. Competency‐based management provides a systematic solution for addressing the competency gap in ULBs, which comprises four components: competency identification, competency assessment, competency development and competency monitoring. The purpose of this paper is to discuss the development of a PPP competencies assessment (PCA) tool for assessment of competencies in ULBs for implementing urban PPP projects.

The analytical hierarchy process (AHP) was used for modeling of competencies involved in urban PPP projects. The application of the PCA tool was showcased with a case study of PPP projects in the municipal solid waste management (MSW) sector.

The PCA tool is effective in assessment of competencies in ULBs. The outputs obtained from the PCA tool provided detailed information on competency profile of the ULB, competency gap and aggregate measure of PPP competencies index.

The study contributes towards the growing body of knowledge on competency development in ULBs for implementing urban PPP projects. The results would also help policy makers to formulate approaches to overcome the competency gap in ULBs.

The purpose of this paper is to analyze involvement of external agencies for supplementing competencies in Indian urban public private partnership (PPP) projects. There are two key aspects which need investigation before making a decision to involve external agencies in urban PPP projects: reasons for involvement of external agencies and competencies to be supplemented by these agencies.

A questionnaire survey was conducted among urban PPP experts and ULB representatives for investigating the above aspects. A case study analysis with five urban PPP projects was also performed for investigating involvement of external agencies in the practical realm.

The reasons for involvement of external agencies to supplement competencies rated high in importance are improvement in quality of deliverables, making available unique competencies for implementing urban PPP projects and transparency in implementation of urban PPP projects. The five most important competencies to be supplemented by external agencies are transaction design, evaluation, project marketing, project development process management and PPP process management.

The study contributes towards the growing body of knowledge on roles and responsibilities of external agencies in urban PPP projects. The results would also help the policy makers to effectively address competency bottlenecks faced by urban PPP projects.

Indicators-based framework has been developed for the sustainability assessment of infrastructure projects but this framework has limitations in quantifying the qualitative parameters. The top-down approach that utilizes principles to assess the sustainability of infrastructure projects has the ability to consider qualitative parameters. The research on the development of principles-based approach is however limited and, in fact, the study on the development of principles to assess the sustainability of public–private partnerships (PPPs) infrastructure projects is in a nascent stage. The purpose of this study is the development of an empirical framework of guiding principles that will facilitate the assessment of PPPs from sustainability perspective. The study has used a grounded theory qualitative approach by using interviews and literature as primary and secondary data sources, respectively, to develop the framework of guiding principles to achieve goals of sustainable infrastructure development through PPPs. The framework comprises 18 guiding principles, which will act as guidelines to facilitate promotion of sustainable practices throughout the life cycle of PPP project so that sustainability goals can be accomplished. The guiding principles could be used as the qualitative parameters for public and private sector to assess the sustainability of PPP infrastructure projects. This chapter presents critical insights on principle-based approach for sustainability assessment of PPP projects, which has not been the focus in the majority of earlier studies.
