This research aims to discuss the impact of using building information modeling (BIM) to manage and completely eliminate structural and facility interferences in a public building project. It also examines the resulting reduction in material waste and rework and the impact on the project’s cost criteria before the implementation phase.
A portion of the public building project was selected for model testing and final optimization. The structure, architecture and mechanical and electrical facilities of the selected area, spanning two floors, were modeled using Revit 2020 software based on AutoCAD maps. The number and methods for identifying structural and facility volume points of interference, and their resolution, were specified. Subsequently, an optimized model, devoid of structural and installation interferences, was prepared. By comparing these two models, the amount of material waste and rework was calculated and presented.
The findings indicate that the lowest imposed cost related to installation was for installation pipes (wastewater, fan coil, hot and cold water consumption), amounting to 180,866,400 IRR. Conversely, the highest and most expensive cost was associated with air ducts, at 1,136,777,000 IRR.
The results of this research demonstrate that using BIM prior to the project implementation phase enables the identification and prevention of structural and facility interferences.
