Identifying risks in implementing sustainable building materials in condominium fit-out projects using analytic hierarchy process

Abstract

Regardless of achieving sustainability through building materials, there are always risks when implementing new techniques and methods. Since this research focused on condominium fit-out projects’ utilization of sustainable materials, it will be useful if risks associated should be identified and analyzed first. The motivation for risk identification in this research focused on the environmental and economic dimensions of sustainability and risk criteria were identified through various literature reviews. The criteria include the following RC1-Adopting with the utilization of sustainable materials, RC2-Appropriate material selections and specifications, RC3-Availability of sustainable materials, RC4-Affordability of sustainable materials, RC5-Project delivery and schedule, and RC6-Scheme of a life-cycle. Prioritization of risk criteria was conducted by Analytic Hierarchy Process (AHP) with the ratings gathered from surveyed construction professionals. The data presented showed that a geometric mean (GM) of normalized principal eigenvector value made three (3) main criteria on top of the list. Namely, RC4 with GM=14.89% at rank number 3; RC6 at rank number 2 with GM=16.22%, and the criterion which garnered a unanimous ranking for all respondents at topmost priority is RC5 having a GM=38.77%. The results obtained can be a guide in planning, navigating, and obtaining significant and favorable results in sustainable initiatives.
