BIM-Based Integrated Approach for Design and Construction Planning of Building Projects

The complexity of construction projects has increased significantly, leading to difficulties in their management. To address this, Building Information Modeling (BIM) has emerged as an integrated process that is widely adopted in the architecture, engineering, and construction (AEC) industry. BIM allows for the modeling and analysis of both design and construction aspects of a building in an integrated manner, thereby minimizing changes during the construction phase. This study aims to conduct a comprehensive literature review and identify research gaps in integrated design-construction planning, while also developing a 3D model of multiple domains of a construction project. Furthermore, the study aims to perform structural analysis of the 3D model, resolve any clashes that arise from multiple domains, and generate a 4D scheduling and 5D costing model for an economically feasible project. The chosen case study is a commercial office building, for which different 3D models were developed using Revit software. Structural analysis was performed using Staad Pro software, and clashes were identified and resolved using Naviswork software. The final clash-free integrated model was used to estimate accurate 4D scheduling and 5D costing of the project in a 3D environment. The study highlights the significance of BIM in minimizing redesigns in projects by enabling the resolution of all issues visually in the design phase. Structural analysis was performed for all 3D models in an integrated manner, demonstrating the effectiveness of BIM in this regard. The proposed methodology focuses on the modeling and analysis of both design and construction aspects of a building in an integrated manner using BIM, which minimizes changes during the construction phase. The study demonstrates the effectiveness of BIM in reducing redesigns in projects by enabling the resolution of all issues visually in the design phase.
