FDOT CCI

The FDOT CCI is a Florida-specific quarterly construction cost index used to track and measure the change in construction costs over time based on FDOT bid data. The FDOT CCI uses a similar approach to the NHCCI Chained Fisher Ideal Index with modified outlier removal. The FDOT CCI Technical Memo describes the development process and outlier removal rules. The FDOT CCI also applies a three-quarter moving average to the final result. Although, the NHCCI methodology cautions users directly comparing indices to the NHCCI as different indices use different methodologies and present different pictures, the FDOT CCI largely follows NHCCI patterns but with timing that more closely reflects Florida specific macroeconomic trends.
