Analytical Hierarchy Process (AHP) based Safety Climate Maturity Model for building construction projects in Tanzania

Abstract

Tanzania's construction boom, while promising, casts a long shadow with its persistent safety challenges. Addressing these concerns requires not just reactive measures, but a proactive approach to cultivating a safety-mature construction environment. This research delves into this crucial aspect, proposing an Analytical Hierarchy Process (AHP)-based safety maturity model specifically tailored to Tanzanian building projects. MS Excel was used to create an Analytical Hierarchy Process by eight Safety and Health experts who tested the approach after the Smart PLS was used to identify important variables using factor reduction. Out of the 143 variables in the questionnaire, 19 factors were identified as essential factors to be used in this study using the Exploratory Factor Analysis (EFA). The general safety climate index (SCI) of 2.60 of the construction projects was determined. It indicated that the safety climate maturity of construction projects is in a compliant level because the range of SCI is within 2-3 (Level 3) indicating the safety climate processes and procedures are formal and defined. This research aspires to be a roadmap and guiding stakeholders towards safer construction sites, a thriving industry, and a brighter future where human well-being and project success go hand in hand.
