The application of Building Information Modeling (BIM) during the project planning phase encompasses initial modeling, model maintenance, cost estimation, and more.
Initially, existing 2D drawings are imported into BIM-enabled software to develop a 3D building model. This early-stage model, known as the initial model, serves as the foundation for BIM’s powerful data analysis capabilities, which can be leveraged to estimate investment costs accurately.
During the schematic design phase, the model allows for precise quantity takeoffs, enabling direct calculation of construction and installation costs. This significantly enhances the accuracy of cost estimates. Additionally, the cost data derived from the model helps evaluate the cost advantages and disadvantages of different design options, facilitating comparison, optimization, and informed decision-making.
Using BIM models to calculate project quantities also reduces the workload for cost engineers since these calculations are automated. This efficiency frees up cost engineers to focus on cost control management tasks, such as analyzing the impact of various construction plans on overall costs, assessing engineering management risks, and exploring cost-saving strategies during construction. These tasks are essential for establishing competitive bidding prices and maximizing the value of cost management efforts.
At the investment decision-making stage, BIM technology plays a crucial role by enabling timely identification of potential project issues and encouraging active participation from all project stakeholders in early project planning.
