The two main construction cost indexes published by Engineering News Record (ENR) are the Building Cost Index (BCI) and the Construction Cost Index (CCI).  Both indexes are based on specific selections of materials and labor types, and reflect the changes in prices for those selections over time. BCI is more applicable to building construction, while CCI is more applicable to heavy civil construction.
