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

DOD Washington Headquarters Service awarded the Total Maximum Daily Load and Paving Contract (TMDL-P), a multiple-award Master IDIQ for design-build and design-bid-build construction on the Pentagon Reservation, with ordering open through Sep 26, 2027. The solicitation advertised a 100% Woman-Owned Small Business set-aside under NAICS 237310, but the 18 task orders issued to date split 11 WOSB (61%) and 7 with no set-aside (39%). The solicitation also required a place of business in Virginia, Maryland, or DC, $15 million per-contract bonding capacity, and $30 million aggregate bonding capacity.

The vehicle was established Sep 27, 2022. Orders per year run 7 in 2022, 4 in 2023, 3 in 2024, 2 in 2025, and 2 in 2026, with the most recent award on Apr 15, 2026, so momentum is tapering. Combined task-order potential value is $64.8 million, of which $57.7 million (89%) is obligated. The solicitation advertised a $135 million ceiling over a 10-year ordering period, while the awarded vehicle carries a shared ceiling of $45 million.

Athena Construction Group, Inc. holds the largest combined potential value at $22.2 million across 3 orders. Addon Services LLC leads on count with 5 orders ($19.7 million), followed by Cedarville Engineering Group LLC with 4 orders ($13.8 million), HDD JV with 2 orders ($7.6 million), and Prestige Development Services Inc. with 2 orders ($1.6 million). These five primes account for 89% of task orders, and two other primes hold the remaining two. DOD Washington Headquarters Service is the sole ordering customer.

Awarded orders buy Pentagon Reservation civil construction: security fencing and bollards, parking structure and parking lot repair, milling and paving, bioretention in parking areas, retaining wall repair, and utility cover upgrades. One order covers the north parking structure at the Mark Center. Solicitation scope also referenced fuel line and fillstand work, which the orders in the source do not show.

The solicitation anticipated task orders from $500,000 to $15 million on a firm-fixed-price basis. The largest awarded order in the source is the North Rotary Road secure fence and bollards order at $12,187,628 (WOSB, completion Apr 30, 2026). The South Secure Parking order carries $10,043,479.50 with no set-aside. Seven orders are minimum-guarantee awards with values from $0 to $10,000; these are contractual floors, not representative order values, and six run to completion on Sep 26, 2032.
