“…Then, snowball sampling was used to reach an adequate number of participants by inviting the participants to forward the survey to others that they deemed appropriate for the survey. Much other research in the construction management field has also employed the same sampling techniques [65][66][67].…”

Building information modeling (BIM) is an emerging process for managing the design, construction, operation, and maintenance of a facility. While BIM has developed in diverse aspects, the lack of organizational BIM capabilities remains a barrier to its implementation across the global architecture, engineering, and construction (AEC) industry. Accordingly, AEC organizations need to understand their organizational BIM capabilities and those of other organizations to realize the benefits of implementing BIM. This study examines the key criteria for assessing organizational BIM capabilities across two countries—Malaysia and Iran. For this purpose, the study compares the assessment criteria for BIM capabilities among the two countries based on the following elements: (1) criticality of the criteria; (2) degree of centrality of the criteria; and (3) underlying groups of the criteria. A systematic literature review of 26 articles and semi-structured interviews with BIM professionals provided nineteen criteria. A total of 121 and 126 BIM professionals evaluated the criticality of the criteria through a survey in Malaysia and Iran. The collected data were analyzed using the contextual disparities test (Mann–Whitney U test, Kruskal–Wallis H test, and rank agreement factor), network analysis, and exploratory factor analysis (EFA). The leading key criteria in both countries are “the company has the necessary infrastructure to implement BIM”, “the company has a good attitude towards new technology”, and “the company understands its expertise”. However, the subsequent key criteria differ between countries. Furthermore, while the level of agreement on the ranking of the criteria is at a neutral level, the Mann–Whitney U test indicates that the level of criticality significantly differs between countries for most criteria. There are also changes in the level of criticality of the criteria between countries. Finally, criteria with a high degree of centrality differ between countries. On the contrary, although the criteria slightly differ between countries, the overarching groups of the criteria are similar (i.e., the criteria are related to organizational BIM capabilities and organizational capabilities). Understanding these criteria can help researchers and industry practitioners develop the optimal tool for assessing organizational BIM capabilities for the local industry.

“…The deployment of SOIs like alternative production methods, new materials and technologies requires the development of new forms of competencies and knowledge. As such, the lack of technical knowledge and understanding constitute barriers to the successful deliver of sustainable and affordable housing (Adabre & Chan, 2020). Since most affordable housing projects in developing countries are constructed by small-to-medium sized enterprises (SMEs) with low internal knowledge and expertise about SOIs, housing developers tend to appoint external experts to assist thereby adding to overhead costs of projects and significantly impacting on the profitability of a development (Pablo & London, 2020).…”

The emergence of a plethora of innovative construction methods, materials and technologies in the construction industry has been projected to enhance the effective delivery of sustainable affordable housing. However, a lack of empirical evidence buttressing an extensive analysis of the effect of internal and external influencers on adopting these innovations within the affordable housing context in developing countries persists.This study examines the nexus between company and project characteristics as internal influencers, and challenges as external influencers, on the extent of use of sustainabilityoriented innovations (SOIs), on affordable housing projects. Variables emanating from an extensive literature review were presented in a causal model detailing sustainable, innovative, and affordable housing (SIAH). The model and the inherent causality between the constructs were validated through a survey administered on a population of registered South African home developers. The results of structural equation modelling posit a minimal positive impact of internal influencers and moderate negative effects of external challenges on the extent of use of SOIs by home developers. Also, results highlighted the negative mediating impact of challenges on the relationship between internal influences and the extent of use of SOI in affordable housing projects. The study concludes that the

“…From the evaluated systems, the only rating system that responds to all economic aspects is BREEAM. However, to increase the acceptance of GBRSs in developing countries, it is essential to indicate economic benefits of the system [65,66], although studies show that energy efficiency and water efficiency can save up to 40% of life cycle cost [67], because high cost is one of the major barriers in green building [68]. Table 5 shows weakness of some rating systems, such as LEED, in this aspect.…”

Sustainability Performance of Green Building Rating Systems (GBRSs) in an Integration Model

In most countries, more than one green building rating system (GBRS) is available on the market. Because of their different approaches, it is difficult to confirm which system can respond to sustainability requirements better. A building considered to be “green” by one Green Building Council (GBC) may fail to satisfy the requirements set by another council. The aim of this study is to evaluate the sustainability performance of GBRSs and establish an integrated model of multi-certification for optimal sustainability. A direct content analysis method was utilized to evaluate GBRSs’ qualitative performance using the ISO sustainable building standards. In this study, seven purposively selected multi-certified buildings were evaluated, and an integrated model was proposed as a better mechanism for the multi-certification process. The proposed integrated model contributes to the achievement of sustainability indicators. The model was implemented on case study buildings, and the proposed combination shows better sustainability performance than existing practice. The developed model helps practitioners in their selection of GBRSs in the multi-certification process. In addition, the performance evaluation of GBRSs will support the future update of GBRSs. The qualitative performance evaluation was performed considering mandatory requirements and prerequisite and credit requirements of selected rating systems, making the work a stronger approach than previous studies.
