The Department of Defense's NAICS 237120 (Oil and Gas Pipeline and Related Structures Construction) market: incumbents, spending trend, set-asides and open solicitations — from FY2026 USAspending awards and live SAM.gov notices.
Contract data as of Oct 30, 2026 (USAspending) · recent coverage verified weekly
| Quarter | Awards | Obligated | Change |
|---|---|---|---|
| Q1 FY2026 | 14 | $34.4M | — |
| Q2 FY2026 | 15 | $11.1M | -68% |
| Q3 FY2026 | 18 | $75.7M | +580% |
| Q4 FY2026 · partial | 15 | $42.0M | -45% |
Federal fiscal quarters (Q1 = Oct–Dec). Awards are counted in the quarter they start; obligations are the award's obligated amount. The Department of Defense publishes contract awards to USAspending with a 90-day delay, so Q4 FY2026 is still missing most DoD awards — treat that quarter as incomplete, not as a spending decline.
The 6 largest incumbents hold 54% of the $724.8M expiring in the next 18 months, across 35 incumbent companies.

Contracts with at least $250K obligated whose final end date — every option exercised — falls in the window, counted from Oct 31, 2026. These are the Recompete Tracker's default filters (18 months, ≥$250K), so the figures match the tracker for NAICS 237120 at Department of Defense. “Obligated to date” is what has been obligated on the contract so far, not the value of the follow-on. An end date is when the work stops, not when the replacement is solicited — that usually happens 6–18 months earlier. Source: USAspending.gov prime awards.
| Offers received | Awards | Share |
|---|---|---|
| 1 | 9 | 50.0% |
| 2 | 5 | 27.8% |
| 3–5 | 3 | 16.7% |
| 6–10 | 1 | 5.6% |
| 11+ | 0 | 0.0% |
From FPDS fields on contract awards that started in FY2026. Offers received is recorded on 29% of these 62 awards and extent competed on 100% — much of the USAspending bulk archive leaves both blank — so each share is over the awards where the field is recorded, not all awards. FPDS's placeholder count of 999 offers is excluded. Task orders under multiple-award vehicles often report the vehicle's offer count, which inflates averages; the single-offer share is the steadier signal. “Not competed” = not competed, not competed under simplified acquisition, or not available for competition (sole-source authorities, including 8(a) directed awards).
| # | Contractor | Obligated | Share |
|---|---|---|---|
| 1 | NOVA GROUP, INC. | $58.0M | 35.5% |
| 2 | GOSHAWK, LLC | $40.2M | 24.6% |
| 3 | S & B INFRASTRUCTURE LTD | $12.9M | 7.9% |
| 4 | CHENEGA RELIABLE SERVICES LLC | $9.8M | 6.0% |
| 5 | ENVIRONMENTAL CHEMICAL CORPORATION | $8.0M | 4.9% |
Registrations are rolled up to their corporate parent (USAspending parent UEI), so a company with several SAM registrations ranks once. Track record: fiscal years FY2015–FY2024 in which the company family received prime awards from any agency (USAspending.gov, by UEI; earlier years aren't loaded), and how many of those years Department of Defense was its largest customer by dollars. Awards and obligations in this table are FY2026.
| Set-aside type | Obligated | Share |
|---|---|---|
| Small business set-aside | $18.8M | 15.7% |
| 8(a) | $41.6M | 34.7% |
| SDVOSB | $0 | 0.0% |
| WOSB / EDWOSB | $0 | 0.0% |
| HUBZone | $0 | 0.0% |
| No set-aside (full & open) | $59.6M | 49.7% |
Share of obligations on awards whose set-aside type is recorded — 74% of this market's dollars. Most USAspending bulk-archive records leave the field blank, so blank awards are excluded rather than counted as full & open.
