    Material selection in the construction industry: a systematic literature review on multi-criteria decision making
    (Springer Nature, 2025-01-21) Bajwa AUR; Siriwardana C; Shahzad W; Naeem MA
    Material choice is critical for ensuring sustainability in the construction industry. Higher carbon embodiment materials contribute towards greenhouse gas emissions and global warming. Decisions on sustainable material selection depend on multiple criteria and variables, thus creating a difficulty to determine the best choice. Multi-Criteria Decision Making (MCDM) techniques have the potential to address this challenge. However, there is limited data that reviews MCDM in choosing building and construction materials. This study aims to review the MCDM methods employed in the sustainable selection of building materials within the construction industry. This systematic literature review (SLR) incorporates meta-analysis and thematic mapping through applying “PRISMA framework” and “Bibliometrix”, respectively. This study explored and analysed the records published from 2010 to 2023. This work identified the critical steps for addressing decision problems in building material selection: Establishing criteria, ranking the hierarchy, comparing the selection criteria, and enabling consistency indices. Moreover, one of the most used MCDM methods, i.e. Analytical Hierarchy Process (AHP) was particularly found particularly useful for the selection criteria and weight assignment of variables regarding the waste, recycled, and composite materials. The involvement of several criteria and alternatives raised the complexity of decision problems, leading to the use of Hybrid MCDM. Hybrid MCDM techniques possess the capacity guide informed decisions for the sustainable material selection in the construction industry.

    Impact of social media usage on performance of construction businesses (CBs) in Abuja-Nigeria
    (Emerald Publishing Limited, 27/07/2021) Oyewobi LO; Olorunyomi OS; Jimoh RA; Rotimi JOB
    Purpose Many construction businesses are currently building and keeping social media pages for their enterprises to be visible to the public to improve their social interaction, promote business interest, build trust and relationships with their targeted audience on social media. The purpose of this study is to examine the impact of social mediausage on performance of construction businesses (CBs) in Abuja, Nigeria. Design/methodology/approach This study used a quantitative research approach by identifying constructs that reveal three aspects of organisation’s physiognomies that impact the process of espousing, implementing and using technological innovations in conducting businesses. Well-structured questionnaire was used to obtain data from 113 purposively sampled building materials’ merchant operating in Dei-Dei Market, Abuja, Nigeria. This study used partial least squares structural equation modelling technique to establish the relationship among the constructs. Findings The results of this study indicated that technology has significant relationship with social media adoption, whereas social media adoption has a very strong positive impact on organisation’s performance (P < 0.001) with respect to improved customer relations and services and enhanced information accessibility. Research limitations/implications This study has implications for CBs that wish to adopt social media to promote their businesses by presenting to them the opportunity to understand the impact of technology, environment and organisational potential in improving business performance. This study is cross-sectional in nature, and this calls for caution in interpreting the results. Originality/value This paper developed and tested a conceptual framework presented to understand the interrelationships amongst the constructs, which would be of great significance to business owners in developing their social interaction and promote business interest via social media. The outcome of this research is beneficial to researchers to further study how the different social media tools could help in influencing business decisions.
