Upon award, the successful bidder must provide payment bonds and certificates of insurance.

This procurement is designated exclusively for certified Small Businesses, with no established Disabled Veteran Business Enterprise (DVBE) contract goal, though DVBE participation is encouraged. The Department establishes no set-asides or restrictions beyond the Small Business certification requirement, and no incumbent vendors or current contractors are identified in the solicitation documents. The approximate project magnitude is valued at $272,400.00, establishing the budget parameters for this contract opportunity.
