Lack of Information technology applications on construction projects lead to complex flow of data during project life cycle. Building Information Modeling (BIM) has gained attention in the Architectural, Engineering and Construction (AEC) industry, envisage the use of virtual n-dimensional (n-D) models to identify potential conflicts in design, construction or operational of any facility. A questionnaire has been designed to investigate perceptions regarding BIM advantages. Around 102 valid responses received from diversified stakeholders. Results showed very low BIM adoption with low level of ‘Buzz’. BIM is a faster and more effective method for designing and construction management, it improves quality of the design and construction and reduces rework during construction; which came out as the top thee advantages according to the perception of AEC professionals of Pakistan.BIM has least impact on reduction of cost, time and human resources. This research is a bench mark study to understand adoption and advantageous of BIM in Pakistan Construction Industry

Prefabricated house-building companies, as suppliers or supply chains, which use manufacturing as a business approach towards industrialization, struggle to implement principles and optimal practices driven from well-established and validated theories in operational research. Supply chain management has a mature body of knowledge that has been widely adopted by research on offsite construction to improve its performance at an organisational level. However, there is no comprehensive review available in the literature for supply chain management theory within prefabricated house building research from the perspective of suppliers. In this study, a systematic review was conducted on the available literature on supply chain management within prefabricated house-building research. Initially, qualitative analysis was performed to identify the key themes. Later, quantitative analyses were applied to validate the overlapping themes and keywords. Further, key trends related to focus, methods and theories or frameworks were reported. The findings were discussed in the context of recent developments in all principal component bodies of supply chain management for future work. This study also provides a brief guide for potential future review studies to explore interdisciplinary intervention within the offsite stream.

In New Zealand, housing is typically low density, with light timber framing being the dominant form of construction with more than 90% of the market. From 2020, as a result of the global pandemic, there was a shortage of timber in New Zealand, resulting in increased popularity for light steel framing, the main alternative to timber for housing. At the same time, the New Zealand government is committed to sustainability practises through legislation and frameworks, such as the reduction of whole-of-life carbon emissions for the building industry. New Zealand recently announced reducing its net greenhouse gas emissions by 50% within 2030. Life cycle assessment (LCA) is a technique for assessing the environmental aspects associated with a product over its life cycle. Despite the popularity of LCA in the construction industry of New Zealand, prior research results seem varied. There is no unified NZ context database to perform an LCA for buildings. Therefore, in this paper, a comprehensive study using LCA was conducted to quantify and compare the quantity of carbon emissions from two commonly designed houses in the Auckland region, one built from light timber and the other from light steel, both designed for a lifespan of 90 years. The cradle-to-cradle system boundary was used for the LCA. From the results of this study, it was found that the light steel house had 12.3% more carbon in total (including embodied and operational carbons) when compared to the light timber house, of which the manufacturing of two houses had a difference of 50.4% in terms of carbon emissions. However, when the end-of-life (EOL) analysis was included, it was found that the extra carbon could be offset due to the steel’s recyclability, reducing the amount of embodied carbon in the manufacturing process. Therefore, there was no significant difference in carbon emissions between the light steel and the light timber building, with the difference being only 12.3%.

Lack of compliance with Occupational Safety and Health (OSH) has resulted in a relatively higher construction accident rate in developing countries such as Pakistan. This study attempts to unveil the aspects of OSH that are ignored and discern the differences in the perceptions of key construction stakeholders. Data collected from 195 respondents were analysed using Cronbach's coefficient alpha, Shapiro‒Wilk and Kruskal‒Wallis tests. The results indicate that OSH training is the most neglected factor, followed by non-inclusion of safety in contract documents and workers' non-involvement. Stakeholders have dissimilar perception about three OSH factors, including management commitment to OSH, safety rules/procedures and policies, and OSH training. Regulatory authority is suggested to launch OSH awareness campaigns, announce safety incentives, institutionalize the OSH certification system, and incorporate safety credit points in contractors' registration process. Though this study pertains to Pakistan, the methodology and the recommendations can be generalized for other developing countries with a similar work environment.

Modular construction (MC) is a promising concept with the potential to revolutionize the construction industry (CI). The sustainability aspects of MC, among its other encouraging facets, have garnered escalated interest and acclaim among the research community, especially in the context of climate change (CC) mitigation efforts. Despite numerous scholarly studies contributing to the understanding of MC, a holistic review of the prevailing literature that systematically documents the impact of utilizing MC on CC mitigation remains scarce. The study conducts a systematic literature review (SLR) of the pertinent literature retrieved from the Scopus repository to explore the relationship between MC and CC mitigation. Employing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol, the SLR was conducted on 31 shortlisted articles published between 2010 and 2023. The findings of the study reveal that MC can mitigate the climate crisis by reducing GHG emissions, curtailing resource intensiveness by enabling a circular economy (CE), fomenting energy efficiency, and fostering resourceful land use and management in the CI. A conceptual framework based on the findings of the previous literature is proposed in this study, which outlines several strategies for CC mitigation that can be implemented by the adoption of MC in the CI. The current study is a humble effort to review various offerings of MC to help mitigate CC in the era of striving for global sustainability. For industry practitioners and policymakers, this study highlights the viability of leveraging MC for CC mitigation, aiming to inspire better decision making for sustainable development in the CI. Similarly, for researchers, it presents MC as a potential tool for CC mitigation that can be further explored in terms of its associated factors, and focused frameworks can be developed.
