Recent data reveals that numerous issues often arise during the completion and handover phases of construction projects. Common problems include the loss of engineering information, incomplete completion data, and errors in drawings.
In traditional cost management models, finalizing project settlements is a challenging and time-consuming task for cost personnel. This is especially true when calculating project quantities. Typically, cost teams from both the contractor and client sides manually verify quantities of components like walls, beams, slabs, and columns one by one. They rely on two-dimensional completion drawings and quantity calculation files generated during the cost estimation phase. This process is labor-intensive and complex, increasing the risk of omissions and inaccuracies in the settlement.
When discrepancies in quantity calculations arise between the parties, a thorough review is necessary. If disagreements occur regarding quantity calculation rules, both sides must collaboratively determine the appropriate standards. Settlement periods vary widely depending on the project, sometimes lasting several months or even years.
The introduction of BIM technology has transformed this scenario. BIM not only accumulates and securely stores complete engineering data but also speeds up the settlement process and enhances accuracy. Throughout construction, as the project evolves, design changes, claims, progress payments, and other relevant data are continuously integrated into the BIM model, ensuring it is consistently updated and refined. By completion and handover, the BIM model contains comprehensive information that accurately reflects the finished project.
Leveraging BIM models to precisely calculate work quantities, combined with detailed unit pricing embedded in the model, streamlines the settlement process. This approach reduces disputes between stakeholders and helps both parties save costs by improving efficiency and transparency.
