Development of risk-based standardized WBS (Work Breakdown Structure) for quality planning of high rise building architectural works

摘要

Work Breakdown Structure (WBS) is a breakdown of project work into smaller components so it can be better managed. Although each project is unique, most buildings can be standardized in their activities to enable the provision of a stronger forecast for project management. Quality performance is also important to be controlled and risk consideration approach is now required for overall quality management process in the updated ISO 9001. Therefore, the development of risk-based WBS for quality planning is proposed. The objective of the study was to develop risk-based WBS for high-quality building architectural works. The research consisted of several stages with qualitative risk analysis method. The result indicates that standardized WBS consists of 5 primary levels and 2 complementary levels, with 14 dominant risk variables on quality performance, and recommended risk responses as the development.
