Improving construction projects' performance through innovative approaches such as lean construction (LC) and offsite construction (OSC) methods are at the centre of various debates. However, there is a limited understanding of the current link between LC and OSC approaches. This study aims to conduct a scientometric analysis on LC and OSC research to unpack and establish the nexus and suggest future research focus.

Scientometric analysis was used to systematically examine existing literature on LC and OSC to identify possible connections. Relevant publications were extracted from the Scopus database, using inclusion and exclusion criteria. VOSviewer software was used as a visualisation technique to analyse and map the interrelations and connections of the concepts being studied. Bibliograhic data on the 68 selected papers were extracted from the Scopus database.

The search results cover the period between 2003 and 2021. Descriptive statistics show that the number of published papers has increased yearly. Researchers in the USA and Canada are the most productive authors regarding the number of published papers. The directions for future research suggested are the need to identify best practices for integrating LC and OSC methods, the need for more interdisciplinary and cross-country collaboration among researchers, the use of alternative research methods will provide a better understanding of the benefit of integrating LC and OSC techniques and more research is needed to showcase how the use of lean and offsite construction can facilitate the attainment of net-zero in the construction industry.

This study provides insights into the trends and gaps in knowledge on integrating LC and OSC methods and offers valuable insights to scholars and practitioners in integrating LC and OSC principles. This knowledge is vital for identifying strategies to improve the outcome of construction projects and contribute to the sustainable socio-economic development of cities across the globe.

The design for deconstruction (DfD) technique, a contemporaneous solution to demolition by optimizing disassembly activities to enable reuse, has recently emerged with several promises to promote the circular economy. However, little attention has been given to its implementation among design professionals, especially in the Global South. Therefore, this study aims to explore the drivers for DfD implementation among design professionals in the Ghanaian construction industry (GCI).

The study adopted a mixed research approach (explanatory sequential design) with an initial quantitative instrument phase, followed by a qualitative data collection phase. Data from the survey were analyzed using mean, standard deviation, one-sample t-Test, and normalization value (NV) test after a review of pertinent literature. These data were then validated through semistructured interviews with ten design professionals with in-depth knowledge of DfD.

The findings revealed that although all ten drivers are important, the eight key drivers for the DfD implementation were identified as, in order of importance, “Availability of computer software applications regarding DfD,” “Inclusion of DfD in the formal education of design professionals,” “Increasing public awareness of the concept of DfD,” “Organizing workshops/seminars for design professionals on the concept of DfD,” “Availability of DfD training,” “Regulation regarding DfD,” “Industry guidance regarding DfD” and “Establishing a market for salvaged construction components.”

This study's findings provide insights into an under-investigated topic in Ghana and offer new and additional information and insights into the current state-of-the-art on the factors that drive DfD implementation.

The purpose of this study is to incorporate a broader set of influencing factors. It is aimed at providing practical insights for policymakers and urban planners to help create equitable and resilient urban areas that improve the quality of life for low-income residents.

This study uses a modeling approach that integrates metropolitan open data to quantify housing expenses. This model evaluates housing affordability by incorporating 30 different criteria that impact household affordability, allowing for a more comprehensive analysis. It adopts a multidisciplinary approach, considering economic, social and environmental factors in assessing urban housing dynamics, thereby providing a holistic understanding of the complex factors that influence affordability.

The research shows that considering multiple factors, including accessibility costs, gives a more accurate measure of housing affordability. Applying the model to Pune reveals the complexity of affordability issues beyond just income and housing costs. The model provides valuable insights for both academic understanding and practical urban housing strategies.

The study’s originality lies in its multidisciplinary approach to provide a more holistic assessment of housing affordability. The research offers a novel method of analyzing housing affordability, which is often overlooked in traditional models. The findings hold value for urban planners and policymakers, providing them with actionable data to support equitable urban development and improved housing conditions for low-income populations.

The rapid urbanization in Nigeria has led to an increased demand for high-rise buildings, yet the construction industry continues to grapple with significant delays that impede project timelines, budgets, performance and the efficiency of post-construction facilities management (FM). Therefore, this study aims to investigate the key delay factors undermining high-rise project delivery in Nigeria using a case study approach to establish fundamental delay causes.

This paper adopted a mixed-method approach using questionnaires and interviews. Questions were formulated on the identified 38 common delay factors from the literature. Data acquired were analyzed using Relative Importance Index (RII), mean score, Kruskal–Wallis test and content analysis.

Key findings revealed 16 critical delay causal factors classified into 4 groups. This study unveils client-related and external factors as the most predominant causative groups. The top five most significant delay causative factors impacting high-rise projects’ performance were identified. Revealed lack of credit facilities and cash flow problems as the main factors inducing unanticipated delay events in high-rise projects. This study found delay factors experienced are excusable and compensable, particularly prominent during the finishing and procurement stages in high-rise projects.

This study unveils the critical delay causes undermining high-rise building project delivery in Nigeria, focusing on both construction and FM perspectives. Through a case study approach, it establishes fundamental delay causative factors and highlights their long-term impact on the operational efficiency and maintenance of high-rise buildings. This study provides built environment professionals insights into key delay factors, offering guidance on modifying work practices to improve project delivery and FM postcompletion.
