How to use this table

Your contract names one determination and one modification. Find the county the work is in and the type of construction (a school is building, a road is highway, a water plant is heavy, houses and apartments up to four stories are residential). A sheet that covers several counties appears on each of their rows.

The rates shown are the current modification. If your contract was awarded under an earlier one, the earlier rates apply for the life of the contract, except on option years and added scope. Which version applies, and how to read the codes.
