The investigation reveals that the completion acceptance stage is the most contentious period for both parties, often due to incomplete information, unreasonable change orders, and data inaccuracies.
In traditional cost management, the final settlement is a challenging task for construction cost personnel, especially when verifying engineering quantities. The process begins with collecting and organizing various change order documents. Then, using construction drawings, work contracts, meeting records, and other relevant documents, the quantity of each sub-item—such as beams, columns, and slabs—is calculated individually. Afterward, group pricing is summarized, and the settlement documents are prepared.
This process requires detailed verification with the cost personnel of the client or consulting party, often causing delays in settlement completion and financial losses for the construction team.
With the support of BIM technology, crucial information like pricing, construction schedules, quantities, and changes from each project stage is stored in the BIM model from the early phases. This data is continuously updated during construction, allowing the model to accurately represent the physical project.
During the settlement review, all relevant data can be directly extracted from the BIM model. Its completeness and accuracy streamline the settlement process, reducing costs for both parties. Thanks to BIM’s computable nature, only modified sections need updates, which are then imported into the approved as-built drawings during quantity settlement. The completed engineering BIM model can be automatically generated, enabling quick calculation of corresponding quantities, identification of discrepancies, and overall improved efficiency in quantity accounting.
By integrating BIM technology with the Internet, the latest policies, regulations, and standards—such as labor cost rates and tax regulations—can be accessed directly. This helps filter and apply the appropriate cost standards in compliance with laws and policies, ensuring accuracy in settlement review.
Furthermore, during project completion settlement, BIM facilitates multidimensional comparisons of engineering projects. Statistical analysis of completed project data across multiple dimensions helps establish an internal enterprise database. This database serves as a valuable reference for future construction projects of similar scope and complexity.
