Measuring the Cost Saving in Building Information Modelling (BIM) Implementation: A Systematic Literature Review (SLR)

Abstract

Building Information Modelling (BIM) has many benefits that could be complex in nature, which call for in-depth examinations into these benefit attributes. While past research often examined these benefits in isolation, this paper looks at how they relate to each other as a strategic step to analyze the quantification technique used by similar measurement metrics. This study examines the measurement process employed in previous studies to measure cost savings from reduced variation and changes using BIM. This paper presents the results of a systematic literature review (SLR) of ten (10) articles. The review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and analyzed using meta-ethnography and thematic qualitative analysis. The measurement processes used by past studies were analyzed in terms of detailed measurement techniques, including the steps, measurement units, and sources of data collection. The findings show that the measurement metric, particularly using cost avoidance, provides a robust mechanism for measuring these savings from reduced variations and changes. The basic steps for the cost avoidance approach were proposed based on the reviewed articles. This includes categorizing issues, performing counterfactual assessments, and conducting valuation processes. This paper helps researchers and policymakers to consider an applied measurement technique to improve efficiency in evaluating BIM benefits.
