Total Maximum Daily Load and Paving Contract (TMDL-P)

DOD Washington Headquarters Service established a multiple-award Master IDIQ on September 27, 2022, for design-build and design-bid-build construction services supporting stormwater management, fuel-line infrastructure, parking, and related civil work on the Pentagon Reservation; ordering closed September 26, 2025, and the vehicle is no longer accepting new task orders.

The vehicle carried a 100% woman-owned small business set-aside at vehicle establishment, though the task-order portfolio shows mixed usage: 10 of 18 orders (56%) were awarded to woman-owned small businesses, with the remaining 8 orders (44%) issued without set-aside designation. The shared ceiling was $45 million. Eighteen task orders worth $64.7 million in combined potential value have been awarded since inception, with $48.2 million obligated (75% of combined potential). Award momentum has decelerated sharply—seven orders in 2022 ramped down to two orders in both 2025 and 2026—reflecting the approaching ordering deadline and the vehicle's limited useful life. The most recent order, awarded April 15, 2026, was a $6.5 million construction services delivery order to an unnamed woman-owned small business awardee with completion targeted for May 31, 2027.

Work is concentrated on the Pentagon Reservation and includes stormwater bio-retention upgrades, permeable pavers, rainwater harvesting systems, tree box filters, security and utility system renovations, bridge and road repair, concrete and asphalt milling and paving, fencing, and underground utilities and fuel-line work. All 18 orders fund DOD Washington Headquarters Service programs; no other federal agencies are customers.

Athena Construction Group, Inc., Addon Services LLC, and Cedarville Engineering Group LLC dominate the awardee base, holding three, five, and four orders respectively and capturing $57.6 million combined potential value (89% of the portfolio). HDD JV and Prestige Development Services Inc. hold the remaining two awardees' share. Task orders range from $10,000 minimum guarantees to $12.2 million; recent substantial awards include a $12.2 million North Rotary Road secure-fence project and a $10 million South Secure Parking design-bid-build project. All orders are firm-fixed-price. Performance periods extend through mid-2027 for active work, though minimum-guarantee delivery orders carry completion dates through 2032.
