Bill of Material & Estimation
3D-modeled bills of material that turn bid packages around in under a week and cut change orders before they start.
Updated
3D modeling streamlines construction planning by providing a detailed view of the project from foundation to ridge vents. Unlike traditional 2D drawings, our BIM models clearly represent stud spacing, framing, drywall, siding, openings, and other construction elements, giving builders, developers, and contractors a complete visual understanding of the project. UBC BIM supports projects across South Carolina, Florida, Texas, California, Australia, New Zealand, Chile, Hyderabad, and Dubai.
What Bill of Material Includes
Traditional bid packages can take weeks to prepare, delaying pricing and project decisions. With UBC BIM’s BIM-driven modeling and estimation services, we can deliver detailed bid packages in under a week, depending on project complexity. Our packages include 3D views, quantity takeoffs, and detailed material information, helping clients review scopes, compare quotes, and make faster, more informed decisions.
A detailed Bill of Materials for CFS, LGSF and wood paired with 3D views doesn’t just speed up bidding—it helps reduce the risk of change orders, back-charges, material shortages, and disputes later. Our BOM can include framing members, studs, tracks, headers, sheathing, drywall, siding, fasteners, hardware, insulation, and other project-specific materials, along with quantities and relevant specifications. Clients can save up to three months through improved estimating and material planning, while gaining better cost control and a smoother construction workflow.
Quantities counted off the framing model of the same house: pieces and length per profile, steel weight from each member's modelled volume at 7,850 kg/m³.

Questions about bill of material & estimation
- How fast can you turn around a bid package?
- In under a week, depending on project complexity. Packages include 3D views, quantity takeoffs and detailed material information.
- What does the bill of material include?
- Framing members, studs, tracks, headers, sheathing, drywall, siding, fasteners, hardware, insulation and other project-specific materials, with quantities and relevant specifications.
- How are the quantities counted?
- Straight off the 3D framing model: pieces and length per profile, and steel weight from each member’s modelled volume, not re-tallied by hand from drawings.
- Do you estimate wood as well as steel?
- Yes. Bills of material cover CFS, LGSF and wood framing.
- What do you need from me?
