Contractors must fill the excavated area with contractor-supplied clay compacted in 6-inch lifts using sheepsfoot rollers or hydraulic plate compactors, bring fill to natural grade with 4 inches of topsoil, and seed the area with full sun lawn mix including starter fertilizer and straw mulch while protecting existing trees. Key project deadlines include March 31, 2026 for utility capping and foundation demolition completion and June 30, 2026 for overall project completion, with liquidated damages of $800.00 per calendar day assessed for delays beyond the deadline.

Qualified contractors must obtain an NPDES Stormwater Discharge Permit (DNR General Permit No. 2) prior to commencing work and demonstrate the ability to provide public liability and property damage insurance with minimum coverage of $250,000 per person and per occurrence, and $500,000 each occurrence.

The contract includes a performance bond requirement equal to 100 percent of the contract price for contracts exceeding $25,000, and the Department will award the contract to the lowest responsive, responsible bidder. The contract specifies a one-year warranty period from final acceptance and includes payment on a lump sum basis within 30 days of receipt of an approved payment request.
