Structural Equation Model (SEM) relationship between location and building height and Work Breakdown Structure toward safety costs at rental apartement project

Occupational Health and Safety at the construction is still hampered from the budget side and mindset that OHS is an additional cost. As a result, decisions related to OHS may not be based on ethical considerations and basic rights to a safe workplace, but in the economic field. This study focuses on analyzing the relationship of building location, height of building and work breakdown structure to OHS costs and further reviewing the factors in these variables that are the dominant effect on OHS costs. The purpose of this study is to analyze the factors in each variable that has a dominant effect on occupational health and safety cost and analyze the relationship between location variable, height of building and WBS to the health and safety cost model in at flat construction projects using Structural Equation Model - Partial Least Square (SEM-PLS).
