Structural Equation Model (SEM) Correlation Between Work Breakdown Structure (WBS), Work Method and Risk Towards Cost Of Safety On Low-Cost Apartments Project

Abstract

Cost of safety is a fundamental aspect that is inevitable to be considered during the construction cost planning phase. The cost of safety estimation is determined based on several factors, including WBS (work breakdown structure), work method, risk and other contributing factors. This estimation is critical in construction, specifically for high rise building constructions. In a case where there is a lack of a suitable methodology in estimating the cost of safety, may incur inaccuracy and uncertainty in determining the actual cost of safety. Besides the mentioned factors, this study will use Structural Equation Model – Partial Least Square (SEM-PLS) in determining the construct model cost of safety, for the case of the build of low-cost apartment building (Rusunawa).
