The Total Maximum Daily Load and Paving Contract (TMDL-P) is a multiple-award Indefinite Delivery/Indefinite Quantity (IDIQ) contract administered by the Washington Headquarters Service for infrastructure and environmental improvement projects within the Pentagon Reservation. The contract supports critical stormwater management and pollution reduction initiatives mandated by the Chesapeake Bay Total Maximum Daily Load requirements, with work primarily focusing on design-build and design-bid-build construction services. Specific project types include stormwater facility renovations, bio-retention modernization, permeable pavement installation, parking lot improvements, security infrastructure upgrades, utility system repairs, and environmental compliance projects.

Task orders under this $45 million contract range from $10,000 minimum guarantee orders to substantial projects valued between $500,000 and $15 million, with completion dates typically extending through 2025-2026. Prime contractors frequently include woman-owned small businesses such as Addon Services LLC, Athena Construction Group, Prestige Development Services, and Cedarville Engineering Group, all of whom have been awarded multiple task orders. The contract originally was set aside for Woman-Owned Small Businesses (WOSB) under NAICS code 237310 (Highway, Street, and Bridge Construction), though recent task orders have been awarded on a full and open basis. Performance locations are concentrated in the National Capital Region, specifically within the Pentagon Reservation in Virginia, with projects addressing environmental compliance, infrastructure modernization, and security enhancement objectives.
