Development of Work Breakdown Structure (WBS) and Standard Operating Procedure (SOP) for Architectural Work Components of High-Rise Buildings with Risk-Based Design-Build Contracts to Improve Project Time Performance

Abstract

This research aims to develop a WBS-based Standard Operating Procedure (SOP) for architectural work components in high-rise buildings with risk-based design contracts. The main problem faced in high-rise building projects is uncertainty that can affect project time performance, which often causes delays and cost overruns. Therefore, risk management is important to improve the efficiency and effectiveness of project implementation. This research is applied to a risk-based WBS and SOP, which is expected to minimize potential risks and improve project time performance. The WBS serves as a tool to break down large jobs into smaller and more structured parts, while the SOP will provide clear operational guidance for each stage of the job. Thus, the synergy between WBS and SOP is expected to provide better control over the implementation of architectural works in high-rise construction projects. The results of this study will show the relationship between risk-based WBS and SOPs in improving project time performance. This research also provides recommendations regarding the proper implementation steps of WBS and SOP for risk-based design-build contracts, which can be applied to similar projects in the future.
