Bidders must demonstrate experience with underground storage vault construction, shoring and dewatering methods, and have a qualified geotechnical engineering firm with at least 5 years of relevant experience.

Notably, this procurement does not mandate minority business enterprise (MBE) or county-based small business participation requirements. The project requires specialized insurance, including railroad protective liability insurance for work within 50 feet of railroad property. Contractors must obtain approvals from multiple agencies and maintain various certifications, including compliance with environmental permits from Prince George's County, Maryland Department of the Environment, and Maryland Department of Natural Resources. The project involves working on a total disturbed area of 3.30 acres, with a drainage area of 107.4 acres and 45.68 acres of impervious surface. Liquidated damages are set at $500 per calendar day for late completion, and the contract will be awarded to the most responsive and responsible bidder meeting the technical and price evaluation criteria.
