MODEL-BASED QUANTITY TAKEOFF

Quantity Takeoff Sheet

Leveraging the parametric features of BIM models, automatically extract the geometric dimensions and physical properties of building components (such as concrete, walls, doors and windows, MEPF routing, and finishing materials). Combined with quantity calculation rules, generate detailed quantity takeoff lists for various components.

Multidisciplinary Coordination and Dynamic Data

Coordinated calculation across architectural, structural, MEP, and interior models enables automatic deduction of overlapping component quantities (e.g., wall openings for doors and windows, or intersecting areas between MEPF routing and equipment), avoiding the duplication and errors common in traditional manual takeoffs. Quantity lists update in real time with design changes, supporting accurate cost control and schedule management.

Application Advantages

Based on the BIM model and project cost rules, generate quantity reports compliant with cost estimation standards. Reports provide accurate data support for bid control pricing, construction cost accounting, and final settlement, enhancing cost management efficiency throughout the project lifecycle.
