Pricing shall be firm and fixed on Exhibit C, itemizing labor by classification and hourly rates, equipment and materials by unit price, and utilities as incurred. The contractor must invoice monthly and submit quarterly progress reports within 30 calendar days of quarter end.

The contract period is one year from the effective date, with the Division of Purchasing retaining the right to renew for three additional one-year periods at its sole discretion.
