Commodities Inflation Forecast
As part of the Agency’s effort to facilitate initiatives toward mitigating the deleterious impacts on project delivery within the state’s STIP and other OTIA projects, Economics & Financial Analysis developed a construction cost outlook and forecast. This outlook is updated every six months.

Forecasts are developed for every fiscal year out to FY19. An important element of the overall outlook is that it is based on, and entirely consistent with, the State Economic Forecast and its associated baseline macroeconomic outlook in effect at the time our projections are developed.

    • Preservation Program,
    • Modernization Program, and
    • An overall composite of all project types.
