About RSMeans data from Gordian

In the construction industry, RSMeans data is synonymous with detailed costs. It has been for decades. Robert Snow Means was a Civil Engineer who kept meticulous construction costs in a series of leather-bound books he made at his kitchen table. By the early 1940s, his peers were so impressed by his tracking of equipment, material and labor costs they began offering to buy his homemade “cost books.”

Today, RSMeans data is offered by Gordian. The database contains more than 92,000 line items and cost engineers spend more than 30,000 hours researching and validating the costs every year. The cost information is still available in books but is also accessible via CD and our dynamic estimating software.

How the Database is Built

Construction costs are comprised of material, labor and/or equipment prices and
can be referenced at the unit, assembly or square foot level of detail.
