The Cordell Building Indices (CBI) are a series of construction industry index figures that are used to monitor the movement in costs associated with building work within particular segments of the industry.

The CBI indicate the rate of change in prices within particular segments of the Australian construction industry.

The changes in prices are measured daily through the use of detailed cost surveys, and are reported on a quarterly basis. This ensures the most current and comprehensive industry information available.

Each index is based on a combination of labour, material, plant hire and subcontract services required to construct buildings within the particular segment being measured.

The CBI measure the change in the cost of constructing buildings, and as such do not provide the actual costs.
