Why 3D BIM Cost Estimating Matters

A three-dimensional building model provides a visual representation of project components while also containing information about modeled elements.

For estimating purposes, this can help project teams connect building components with quantities and applicable construction costs.

From 3D Model to Construction Cost

We review the available BIM model and identify relevant building elements that can support quantity and cost development.

Modeled quantities can then be organized by building system, element, material, trade, floor, or other project-specific categories.

3D BIM Estimating Across Construction Trades

3D BIM cost estimating can support:

  • Concrete
  • Structural steel
  • Framing
  • Roofing
  • Walls
  • Doors and windows
  • Finishes
  • HVAC
  • Plumbing
  • Electrical
  • Other modeled construction systems

Visual Model-Based Cost Review

The three-dimensional nature of BIM allows project teams to associate costs with physical building components.

This can make it easier to review where quantities originate and understand how specific design elements contribute to the overall construction cost.

Design Changes & Cost Impact

When updated model information is available, quantities can be compared against previous model information to identify changes that may affect construction costs.

This can support design-stage cost monitoring and budget review.

3D BIM vs. 5D BIM Estimating

3D BIM focuses on the three-dimensional representation of building components and the use of that model information for quantity and cost development.

5D BIM extends the BIM workflow by connecting model information with cost data and supporting more integrated cost management throughout the project lifecycle.
