The advantages of applying BIM technology in engineering auditing can be summarized in three key aspects:
1. Enabling true tracking audits. Engineering project audits are inherently complex, with extended timelines and high levels of difficulty. These projects generate vast amounts of information and data, which traditional auditing methods struggle to track accurately. With BIM, project bidding information is clearly represented, allowing auditors—once authorized—to export necessary quotation details and provide timely feedback. This helps minimize losses from unreasonable bids. During the design phase, auditors can examine the 3D model thoroughly to identify potential issues early, reducing risks caused by design flaws. Throughout construction, BIM data allows auditors to monitor progress and events in real time, overseeing the entire process. Finally, during project settlement, auditors can review preliminary BIM data to assess the reasonableness of final costs and settlements.
2. More accurate quantity calculations and improved cost control. Traditional auditing relies on manual quantity calculations based on 2D CAD drawings, which are prone to errors and inconsistencies. These inaccuracies can compromise audit quality and cost management. BIM eliminates complex manual calculations by enabling auditors to export all necessary quantity data directly from the model, significantly saving time. This shift allows auditors to focus more on cost control, enhancing supervision and reducing waste. Moreover, as project data in BIM is dynamically updated, auditors can track quantity changes throughout the project lifecycle, providing timely audit opinions that effectively manage costs.
3. Advancing the digitalization of engineering audit data. Under traditional auditing models, all information must be returned to the original parties, making it difficult to convert data into reusable knowledge. BIM’s computational model allows auditors to extract necessary information electronically, creating digital files that can be stored and shared efficiently. Additionally, BIM facilitates the storage of extensive audit data—from initial evidence to final reports—on a cloud platform organized by project and timeline. This streamlined access improves data retrieval and audit efficiency, promoting the overall digital transformation of engineering auditing.
