A structure was built 10 years ago for X dollars. What would it cost to build today?
RSMeans includes Historical Cost Indexes to calculate this. The Historical Index page is just before the City Cost Indexes in our hard copy books and in the Reference section of any CostWorks data. Included on the page is an explanation of the equation that allows you to move any construction cost forward or backward in time. Note: When used in conjunction with the City Cost Indexes it is possible to move any cost from one city and time to another city and time.
