Building Cost Estimating for New Construction and Additions

Complete cost estimates for whole buildings, from foundations and structure to envelope, interiors and services, so owners and contractors know the full price before they commit.

Full Building Costs

Know What the Whole Building Will Cost

Building cost estimating looks at a project as a complete structure rather than a list of separate trades. The goal is a reliable total that includes everything needed to build, from the first excavation to the final coat of paint. Owners use this number to secure funding, and contractors use it to set a realistic contract value.

Our estimators break the building into its main systems: substructure, superstructure, exterior enclosure, roofing, interior construction, services and sitework. Each system is measured and priced, then combined into a clear summary that shows where the money goes.

This approach makes it easy to see the effect of design decisions. Changing the structural system, the façade or the mechanical approach immediately shows up in the totals.

Process

Our Building Estimate Process

A system-by-system approach that gives a full picture of the building cost.

Define the building

We confirm the gross area, use, number of floors and structural system.

Measure each system

Each building system is taken off from the drawings in detail.

Apply local costs

Labor and materials are priced for the project location and market.

Summarize & compare

Costs are shown by system, by floor and per square foot.

Who Needs a Building Cost Estimate

Developers and property owners use building estimates to check feasibility and support financing applications. General contractors use them to prepare lump-sum proposals, and architects use them to confirm that the design matches the client’s budget before construction documents are finished.

We estimate new buildings and large additions in residential, commercial, institutional and light industrial sectors.

Cost Factors

What Shapes the Cost of a Building

These decisions have the biggest influence on total building cost.

Structural system

Steel, concrete and wood frames differ in material, labor and schedule cost.

Building height

More floors add structure, vertical transport and life-safety systems.

Façade choice

Brick, metal panel, glass curtain wall and stucco vary widely in price.

Floor-to-floor height

Taller floors increase wall area, structure and duct runs.

Building efficiency

The ratio of usable area to gross area affects cost per usable square foot.

Specification level

Material and system quality can move the total far more than size alone.

FAQ

Building Cost Estimating Questions

What owners and contractors usually ask.

How is building cost estimating different from a takeoff?

A takeoff lists quantities. A building cost estimate prices every system and combines them into a total project cost.

Can you show cost per square foot?

Yes. Summaries include total cost, cost by system and cost per gross square foot.

Do you include sitework?

Yes, when site drawings are provided. Sitework and utilities are shown separately from the building.

Can you estimate an addition to an existing building?

Yes. We include tie-ins, demolition and work to existing areas where shown on the plans.
