Escalation, with its work shown.

Project cost escalation to the midpoint of construction from the latest final-cost data. Ranges, not point estimates. Every assumption is documented below the result.

Commercial: +3.9% y/y; trailing 12 mo · May 2026
Public: +3.6% y/y; trailing 12 mo · May 2026
Multifamily: +3.4% y/y; trailing 12 mo · May 2026
Infrastructure: +3.7% y/y; trailing 12 mo · May 2026

Current trailing escalation by project type, from BLS selling-price indices. The drivers behind these rates, demand, inputs, and financing, are read top to bottom on the front page.

If a number here would change a bid by more than 1%, verify it against your firm's own historical cost data before relying on it. The model and its measured accuracy are on the methodology page: the band is the model's own out-of-sample error, including the places where naive baselines beat it.
