Currently, it is quite common for the final settlement costs in construction projects to exceed the initial budget. Therefore, strengthening cost control throughout the entire construction process has become a crucial aspect of effective project management.
Due to the highly dynamic and unpredictable nature of construction, analyzing and managing resources and costs can be quite challenging. This difficulty is especially pronounced when engineering changes require extensive time to adjust budget estimates. As a result, the workload for cost accounting can increase exponentially, leading to inefficiencies in cost management. Furthermore, during the construction phase, collaboration among project stakeholders is often limited, with each party focusing primarily on their own interests. While cost accounting and control are emphasized during and after construction, the importance of early-stage cost control is frequently overlooked, which inadvertently causes significant resource waste and cost overruns.
BIM-based cost control offers a solution by enhancing cost management throughout the project lifecycle, particularly during the early phases. Stakeholders collaborate within the BIM model on design, clash detection, and pre-construction simulations. This collaborative environment allows for timely identification and optimization of potential design issues before actual construction begins, effectively reducing risks associated with decision-making errors and design changes, and ultimately saving costs. Additionally, BIM technology enables rapid and accurate calculations of the entire project lifecycle costs. When design changes occur, the BIM model’s linked update feature allows for quick adjustments to pricing data and budget estimates, significantly improving cost control capabilities.
