“…While other studies integrated CBA with other methods. Chauhan et al (2019) applied CBA together with cost-benefit analysis to define a process for measuring the impact of prefabrication. Perez and Arroyo (2019) focused on analysing the environmental public policy design process using the CBA decision system integrated with the Design Structure Matrix (DSM) to make complex decisions.…”

“…Among the benefits that CBA provides are the following: (1) It Generates transparency in the decision-making process and allows explicit consideration of multiple alternatives based on various impact factors (Parrish and Tommelein 2009;Arroyo et al 2012;Chauhan et al 2019;Arroyo et al 2014). (2) It helps generate consensus based on the decision and promotes continuous learning (Parrish and Tommelein 2009;Arroyo et al 2012;Chauhan et al 2019;Arroyo et al 2014). (3) It helps to document information on why and on what basis decisions are made, so that they can be reviewed at a later time or in a future project (Parrish and Tommelein 2009).…”

On January 30 of 2020, The World Health Organization declared the pandemic crisis as the first public emergency with international importance. Because of this, many building projects were paralyzed since then and the building industry experienced changes that have brought the inclusion of new tools to achieve the objectives of the projects. The purpose of the present paper is to present the application of Choosing By Advantages (CBA) methodology to select the best alternative in the material removal system in the execution of basements in a project that was paralyzed by the health emergency COVID-19. CBA is a lean tool used to make decisions with clarity and transparency and in this case is used to consider the constraints of COVID-19 protocol to guide in decisions making. This methodology was applied to a case study for a building project in the basement construction phase that restarts its activities in the excavations. For that, an expert panel was formed to analyze and decide the best alternative solution. Finally, the selected alternative was implemented on-site, validating the methodology. It is concluded that CBA is an excellent tool to transparently document the selection process of the removal system. Additionally, this methodology allows including activities regarding the COVID-19 protocol, without affecting the project's productivity.

“…This can affect the construction process directly because the loss of quality and time due to harsh weather can be avoided. It can also indirectly influence the construction process because weather conditions can damage building materials (Chauhan et al 2019), decreasing material availability. Due to less time spent on site, the risk of weather-related accidents is also lower (Durdyev and Ismail 2019).…”

Despite the efforts of governments and firms, the construction industry is trailing other industries in labour productivity. Construction companies are interested in increasing their labour productivity, particularly when demand grows and construction firms cope with labour shortages. Off-site construction has proved to be a favourable policy to increase labour productivity. However, a complete understanding of the factors affecting construction labour productivity is lacking, and it is unclear which factors are influenced by off-site construction. This study developed a conceptual model describing how 15 factors influence the construction process and make a difference in labour productivity between off-site and on-site construction. The conceptual model shows that all 15 factors affect labour productivity in three ways: through direct effects, indirect effects and causal loops. The model is a starting point for further research to determine the impact of offsite construction on labour productivity.

“…During the third year, the prefabrication research theme from the previous year was continued by developing a multi-criteria tool to evaluate the versatile impacts of prefabrication (Chauhan et al, 2019). The research showed that the tool helps project stakeholders to communicate about multifaceted impacts of production methods and to make the final decision on whether to prefabricate or not.…”

Purpose University research efforts have not been effective in developing lasting impacts on operations management in construction because of inadequate coordination between academia and industry. This study aims to describe the development of an industry–university (IU) relationship which has enabled the conduct of practically and scientifically relevant research. Design/methodology/approach Design science research was carried out between 2016 and 2019 to build a consortium between a university and 17 design, construction, technology and logistics companies for enabling process innovations in construction. The consortium conducted industry-funded research on various topics, such as takt production, lean design management, prefabrication, measurement of waste and business models supported by digitalisation. The academic and practical impacts of the consortium’s research projects were investigated through a survey and in-depth company interviews. Findings The paper presents a conceptual model for creating an IU relationship to support scientifically and practically relevant research. The model includes network architects who mobilised consortium development and a joint governance body that developed a shared long-term vision and selected research topics based on this vision. The results show that using the model’s approach, the consortium selected research topics that have led to both academic publications and process innovations in construction. Originality/value Using empirical data, this study describes how to create a win-win IU innovation relationship that enables the implementation of process innovations into the construction sector and, at the same time, the conduct of scientific research in construction management.
