What is the difference?
RSMeans (published by Gordian) is a construction cost database: tens of thousands of unit-cost line items organized by CSI MasterFormat, with national average pricing and a City Cost Index you apply to adjust those averages to one of roughly 970 US and Canadian locations. It is a trusted reference — but it is data you feed into your own estimating process.
OneEstimate is cloud estimating software. It builds the estimate for you with AI, includes blueprint takeoff, and is designed so you work from real local material and labor rates for your state and city — not a single national average adjusted by one multiplier. You start free and estimate entirely in your browser.

Where OneEstimate stands out
Local costs, not national averages
With RSMeans you adjust a national number with a city index. OneEstimate is built so you work from real local rates for the market where you actually build.
