BIM Quantity Takeoff and Estimating Services in the USA

We pull your quantities straight from the model, not by hand off PDFs. Faster takeoffs, fewer misses, and numbers that update when the design changes.

Counting quantities off PDFs is slow, and a late design change can undo the count. Model-based takeoffs solve both. Excelize pulls quantities straight from the BIM, so they’re fast, consistent, and easy to defend.

Quantities straight from the model What we deliver
What It Is

What is a model-based quantity takeoff?

A quantity takeoff is the count of materials and work a project needs, the basis for every estimate. A model-based takeoff pulls those quantities straight from the BIM instead of measuring drawings by hand. Because the numbers come from the model, they stay consistent and update when the design changes. Excelize produces model-based takeoffs for U.S. contractors and estimators, linked to your cost codes.

What We Deliver

What our quantity takeoff service includes

Model-based quantities

Counts and measures pulled directly from the BIM, by trade and assembly.

Cost-code linking

Quantities mapped to your cost codes or estimating system.

Trade takeoffs

Concrete, steel, architectural, and MEP quantities to the detail you need.

Change tracking

Quantities re-run when the design changes, with the deltas shown.

Takeoff from your model or ours

We use your model, or build one to take off from.

Defensible and QA-checked

Quantities checked against the model, so they hold up in review.

Our Process

Our quantity takeoff process

01

Inputs

We confirm your model or drawings, your trades, and your cost codes.

02

Model prep

We check the model is takeoff-ready, or model what’s missing.

03

Takeoff

Quantities extracted by trade and assembly.

04

Cost-code mapping and QA

Mapped to your codes and checked against the model.

05

Handoff

Quantities in your format, ready to drop into your estimate.

Tools & Standards

Quantity takeoff tools and standards we use

01

Software

Revit, Navisworks, and takeoff tools, exported to Excel or your estimating system.

02

Standards

Your cost-code structure (CSI MasterFormat or your own), and AIA G202 LOD.

03

Inputs

Your Revit or IFC model, or 2D drawings we model from.

04

Formats

Excel, CSV, and direct exports to your estimating tool.

Where We Apply It

Quantity takeoffs by trade

The takeoffs U.S. estimators ask us for most:

Concrete and structure quantity takeoffs

Concrete and structure

Volumes, rebar, and formwork by element.

Steel and metals quantity takeoffs

Steel and metals

Tonnage and member counts.

Architectural quantity takeoffs

Architectural

Walls, finishes, doors, and openings.

MEP quantity takeoffs

MEP

Duct, pipe, conduit, and fixtures by system.

Why It Matters

Why model-based takeoffs pay off

Manual takeoffs are slow, and they drift. Two estimators measure the same set and get two different numbers. Pull the quantities from the model, and they’re consistent every time, and they update the moment the design does. That’s fewer hours, fewer misses, and an estimate you can defend.
