The completion acceptance phase marks the final and crucial stage of an engineering project. The final settlement not only determines the project’s ultimate cost but also directly impacts the interests of both the construction and contracting parties. During this process, auditors must gather comprehensive project documentation, including bidding documents, engineering contracts and amendments, change orders, material price lists, meeting minutes, technical disclosures, and construction audiovisual records. These materials must be verified in collaboration with the construction party, the contractor, and the supervising party.
During the audit, a thorough review is conducted to ensure the accuracy of quantity extraction, compliance with engineering measurement and pricing standards, validity of change orders, determination of provisional estimates, quotation bases, and consistency between completion drawings and actual site conditions. Once all assessments are finalized, auditors issue a completion settlement audit report.
Common issues encountered at this stage include unclear or inaccurate change orders and an increasing volume of modifications. Violations in quantity calculations are frequent, such as duplicated, inflated, or incorrect measurements. Material prices often do not correspond to actual site conditions. Additionally, errors in drawings, loss of information, and the challenges of reflecting on-site conditions in two-dimensional as-built drawings complicate subsequent operation and maintenance management. Projects lacking follow-up audits often prioritize completion settlement audits, which leads auditors to face complex and fragmented information, making audits difficult and often resulting in unsatisfactory outcomes.
Leveraging BIM technology for settlement audits significantly simplifies the auditor’s workload by representing completion outcomes within a comprehensive three-dimensional model.
In auditing completion settlement data, BIM’s 3D models integrate engineering components, pricing information, calculation rules, construction schedules, contract details, and change orders into a unified database. This extensive platform allows auditors to quickly access relevant information based on location, component, or timeline, eliminating the need for laborious document searches and manual cross-checking.
For auditing project quantities, BIM utilizes three-dimensional Boolean calculations. Auditors can adjust the model to reflect the actual completion status compared to the original bidding data, creating an updated completion model. By importing completion drawings from the contractor into BIM software, a detailed 3D completion model is automatically generated. When models from both parties are loaded into BIM measurement software, discrepancies are highlighted automatically, enabling auditors to measure quantities more efficiently and with greater precision.
Regarding cost auditing, BIM integrates internet technologies to provide real-time updates to policies, regulations, pricing rules, and professional quotas—such as adjustment coefficients and tax rates. BIM automatically recalibrates cost standards according to these updated factors, ensuring accurate settlement audits while reducing the auditors’ manual workload.
