A Case Study of Preparing and Managing Final As-Built Model for Owner Beyond Project Closeout

As the application of building information modeling (BIM) becomes more common, BIM model management becomes necessary and important to enhance the effectiveness of BIM implementation during the construction phase. The completeness and accuracy of a final as-built model is necessary and important for a general contractor (GC) beyond project closeout. BIM model inspection (BMI) is one of the major works executed by GCs for the completeness and accuracy of a final as-built model. Furthermore, final as-built BIM model management is now recognized as the most critical BIM management strategy in construction management. However, there are many problems in a final as-built model that exist in practice because of a final asbuilt model mismatch, the lack of final as-built models, and incorrect information entry of final as-built models. In order to solve the problems, this chapter proposes a final asbuilt BIM model inspection and management approach when preparing the final asbuilt model beyond project closeout. The utilization of the proposed approach can effectively manage the status and results of the final as-built BIM model inspection and management work performed. The proposed approach was applied in a selected building case study in Taiwan to verify our proposed approach and to demonstrate the effectiveness of preparing and managing a final as-built BIM model practically. Additionally, this chapter identifies the benefits, limitations, and problems encountered through real cases. Finally, conclusion and suggestions are summarized for further applications. We expect the effective use of the proposed approach to significantly help GCs to handle the final as-built BIM model inspection and management work effectively for the owner beyond project closeout.
