CWCCIS Indices

For explanatory text, see Engineer Manual (EM) 1110-2-1304, Civil Works Construction Cost Index System (CWCCIS).

These cost indices are provided for use in the escalation of U.S. Army Corps of Engineers (USACE) Civil Works project costs.

For programming and budget preparation purposes, project costs are escalated for inflation.  Indices used to escalate costs from the past to the present are developed from actual historic data.  Indices for future escalation are developed using the “Updating Factors” in table 1, of the Engineer Circular (EC)(number changes yearly), Civil Works Direct Program Development Policy Guidance.  These factors are based on the current annual Office of Management and Budget (OMB) inflation factors.
