Advancing BIM Processes for Composite Structural Systems: A Case Study of an Incubation Center in Turkiye

The parameters planned for construction projects to be realized in the construction industry are sensitive to cost estimation errors. Developed countries have increased the performance of contractor firms by making the use of BIM technology mandatory to meet the increasing requirements of the construction industry. However, traditional approaches, still used in many countries, are prone to error. This study aims to develop 3D to 5D BIM models for an incubation center project in Türkiye, where BIM technology is not yet mandatory and no official standards have been published. The composite project structure consists of reinforced concrete & steel structural systems. The project has been procured within the scope of Turkish Public Procurement Law. Autodesk Revit and Tekla Structures were used for 3D modeling. The 3D-BIM model at the LOD 400 level was obtained. The obtained quantity data were then processed on the work program, prepared in Primavera P6, and a time and cost schedule were prepared for 52 production items. The 5D-BIM cost simulation was designed via Autodesk Navisworks Manage. The results indicate that the construction cost estimations, which can be obtained by using the 5D-BIM method and financial risk management methodology together, will be beneficial for the tender stakeholders.
