BENEFITS AND ROI OF BUILDING INFORMATION MODELING (BIM) FOR MULTI-DISCIPLINARY PROJECT MANAGEMENT : A SINGAPORE PERSPECTIVE

Abstract

BIM is not a panacea for a lack of productivity, lack of experience or lack of knowledge. It is integral for a company to establish an efficient link between the core competencies of its practice and the use of BIM to derive benefits. Building Information Modeling (BIM) is perceived as the next-generation solution to enhance productivity of the construction industry holistically and streamline the delivery process of buildings and structures. However, there is limited evidence showcasing the existence of frameworks or formulas for companies to optimize the benefits and ROI of BIM, particularly in the local context. Local researches demonstrating the benefits and ROI of BIM are unavailable as well This study focuses on the project- and company-level benefits as well as ROI of BIM implementations – particularly in the local context. It analyzes how experience level and discipline of users will affect the derivation of BIM benefits and change in project cost, schedule, quality and safety. Quantitative data was collated through a survey questionnaire designed and sent out to consultants and contractors operating in Singapore and the results were analyzed using various statistical instruments. Qualitative information describing the in-depth benefits of BIM was also studied through two local multi-disciplinary cases. It was subsequently found and statistically proven that BIM benefits is affected by users’ experience level and discipline. To tackle the research problem, two models were proposed using the results of the findings. The first model is a self-assessment BIM Optimization Framework while the second is a formula to calculate the cash-flow, ROI and payback period for BIM implementations – to provide both objective and subjective evaluations. Recommendations are also made to local companies operating in the built environment.
