What are the benefits of BIM for engineering cost management? While everyone may have their own perspective, today the BIM Building Training Network will discuss the key advantages BIM brings to controlling engineering costs.
1. Clash Detection: Since architectural, structural, and MEP (mechanical, electrical, and plumbing) systems share the same model information, it becomes much easier to intuitively identify and resolve conflicts both within and between disciplines. BIM’s clash detection capabilities help reduce costly rework by catching issues early in the design phase.
2. Virtual Construction: Implementing Integrated Project Delivery (IPD) involves collaboration among owners, designers, general contractors, subcontractors, consultants, and other stakeholders during the design process. Using BIM for virtual construction enables these parties to collectively improve designs and achieve shared benefits and risk mitigation through contractual agreements.
3. Quantity Takeoff and Decomposition: BIM’s professional analysis tools are highly valued for extracting accurate data from design models. These tools support a wide range of functions including quantity estimation, structural analysis, project management, and equipment tracking. Quantity estimation, in particular, is critical as it provides foundational data used by owners, contractors, suppliers, and managers to control construction costs.
However, BIM analysis tools alone cannot replace specialized 3D quantity calculation software. To achieve precise quantity data, professional software that incorporates national standards, codes, and calculation rules is necessary. These tools use advanced 3D Boolean operations and entity deductions to generate quantities that are far more accurate than manual calculations. Additionally, they can automatically produce electronic documents for data exchange, sharing, remote transmission, and permanent archiving.
The quantity of work is the cornerstone of all cost management activities, including cost estimation, bidding, negotiations, contract signing, and progress payments.
4. Efficiency Improvement: BIM models can be shared across disciplines, eliminating redundant modeling efforts in civil engineering, rebar detailing, and installations. This avoids duplicated data entry and enhances communication, collaboration, and integration among all teams involved. The manpower saved can then be redirected to more value-added cost control activities such as business negotiations, bidding, and contract management.
In summary, the benefits BIM offers to engineering cost management are clear and substantial. It is these advantages that have driven the widespread adoption of BIM in the field of engineering cost control.
