ABSTRACT
This chapter begins with a building information model for quantity surveying (QS-BIM) execution plan, which can be perceived as an extension of the general BIM execution plan, with a focus on QS. It presents the critical success factors of adopting BIM for cost management. These factors include the demand for a QS-BIM, which aims to define how such BIM should look like when developed for cost management. The chapter describes the compatibility of BIM with existing QS practices and software development. The implementation of BIM for QS practice generally involves various parties to develop, maintain, and analyse BIM for cost-related tasks. At the construction stage, the information contained in the as-designed BIM will be updated to an as-built BIM by synchronising it with the actual construction information. BIM is expected to enable an efficient preliminary estimate and generate reliable estimation results to facilitate the subsequent cost-related tasks.
