The main challenges during the completion acceptance stage are as follows:
First, acceptance personnel often focus solely on quality inspection, neglecting the assessment of functional performance. Second, there is insufficient oversight of the overall project during acceptance—for example, whether the entire pipeline layout complies with design and construction standards, if it is visually appealing, or if it allows for convenient future maintenance. This lack of comprehensive evaluation leads to an absence of intuitive judgment.
Third, the completion drawings frequently fail to accurately represent the actual site conditions, resulting in unforeseen issues during operation and maintenance, thereby increasing management complexity.
Application of BIM in the Completion Acceptance Stage
These issues can be effectively addressed by comparing a comprehensive, data-driven, and visualized BIM model with the physical structures constructed on site.
(1) Using models from the design and construction phases, acceptance personnel can clearly and visually understand the entire project, covering various disciplines such as architecture, structural engineering, plumbing, heating, and electrical systems. This approach facilitates not only the verification of functionality and overall quality but also supports detailed inspections by different departments.
(2) The acceptance process can leverage BIM models to verify actual on-site conditions, checking whether pipeline placements meet specifications and support convenient future maintenance.
(3) By creating a completion model, key information related to design, cost, and management is integrated into a single resource. This model becomes a valuable tool for operation and maintenance teams, enabling quicker and more efficient access to project data and providing robust support for ongoing facility management.
