Product Details

The BNi Square Foot Costbook is our most comprehensive guide to square-foot estimating because it includes 80 detailed cost models covering virtually every type of building project.

 All of the cost models in this guide take into account the impact of the unique challenges we face in estimating today including inflation, supply chain shortages,  and prevailing wage rate hikes.

In this Costbook you'll find detailed square foot cost studies for:

• Civic government buildings
• Commercial buildings (including renovations)
• Educational buildings (including sustainable)
• Hotels
• Industrial buildings (including renovations and LEED rated)
• Office buildings (including renovations and sustainable)
• Religious buildings
• And residential buildings

For each building project, you get a detailed narrative with background information on the specific project. This lets you put the cost data into context and make appropriate adjustments to your own projections. In addition, you'll receive unit-in-place costs for nearly 15,000 items and materials used in all types of construction. For each item, you can see man-hours, as well as labor/equipment and material costs, all clearly broken out.

You also get Assemblies!

The 2023 edition of the  BNi Square Foot Costbook also includes an extensive section featuring Assemblies tables listing systems for commercial construction, each broken down by its respective unit price components.  This section helps simplify estimating by providing construction costs by assembly type, represented by the major categories designated by ASTM E1557-09.

Developed in partnership with Design Cost Data, and BNi Building News, this ready-reference Costbook also features illustrations of each building type, a guide to 52-year cost trends for inflation costs on building materials, plus detailed unit-in-place costs for thousands of items -- from asphalt and anchor bolts to vents and wall louvers.
