MassDOT special provisions

This information is for use on all MassDOT Highway Division construction contracts that contain special provisions for price adjustments for Liquid Asphalt, Portland Cement Concrete, Diesel Fuel, Gasoline, Structural Steel and Reinforcing Steel.

The special provisions provide a price adjustment of affected items. This adjustment is based on the difference between the Base Price and the Period Price. The Base Price is found in the Notice to Contractors section of the Bid Documents. 

The table on the Price Adjustments page lists the Period Prices, except for those of structural and reinforcing steel. Use the information under Steel to determine structural and reinforcing steel Period Prices.

"Asphalt Weekly Monitor''.
