About E2 Consulting Engineers, Inc.
E2 Consulting Engineers, Inc. Corporate Headquarters Division, a minority-owned, Subchapter S corporation based in Denver, Colorado, provides environmental remediation, infrastructure engineering, and technical support services to federal agencies predominantly as a prime contractor (98% of recent awards). The company is Subcontinent Asian American-owned and operates with a portfolio concentrated in Superfund site oversight, hazardous-waste remediation, and water-infrastructure engineering under the EPA Remedial Acquisition Framework and Army Corps of Engineers contracts, competing across full-and-open and total small business set-aside categories.
E2's customer base spans thirteen federal agencies, but concentration is extreme and driven by a single large vehicle. The Environmental Protection Agency Office of Land and Emergency Management dominates by potential value at $255 million combined potential value from one award, representing 90% of the vendor's total $281.4 million portfolio. By award count, the Department of the Army Corps of Engineers Engineering District Rock Island leads at fifteen awards ($446 thousand combined potential value), followed by the Portland and Los Angeles engineering districts (six and five awards respectively, with Los Angeles anchoring $18.1 million). EPA Region 10 accounts for three awards totaling $1.1 million. The divergence between value and volume rankings—EPA by dollars, Army Corps by count—reflects E2's mix of high-ceiling EPA parent vehicles and numerous smaller Corps delivery orders.
On the EPA Remedial Acquisition Framework for Environmental Services and Operations, E2 holds four task orders valued at $1.7 million combined potential value, with recent work including a $690,735 total small business set-aside delivery order from EPA Region 10 for Bradford Island Superfund Site oversight in Cascade Locks, Oregon (completion April 2029), a $169,280 time-and-materials delivery order from EPA Region 10 for Terminal 108 environmental remediation in Seattle, Washington (completion November 2028), and a $566,157 delivery order from EPA Region 9 for technical support at the Ordot Landfill Superfund site in Guam (completed December 2026). On the Army Corps of Engineers Indefinite Delivery Contract W912PL11D0007, E2 holds four task orders valued at $8.1 million combined potential value. E2 also maintains a seat on the Federal Supply Schedule GS10F0192P with 25 task orders ($1.6 million combined potential value).
Activity is sparse and episodic—one award per year across 2022 through 2026—with minimal recompete exposure over the next twenty-four months (one award, $566 thousand potential value reaching ultimate completion). The vendor's sub-engagement footprint is negligible; across the entire prime contract portfolio, SCI-reportable prime records show zero sub-hours share, and named sub-award activity consists of one modification notice for the Idaho Cleanup Project under an unspecified prime. This is entirely a prime-contractor operation with no material teaming or sub-leveraging signal.
SCI-reported invoicing is immaterial and inconsistent: $35 thousand in FY2023 across 0.1 FTEs on prime records, with zero invoicing in FY2024. The FTE trajectory shows 113 FTEs across two sub records in FY2022, scaling to 0.1 FTEs on two prime records in FY2023, then recovering to 114 FTEs in FY2024 (two prime, one sub). This volatility reflects the threshold-based nature of SCI reporting (contracts above $150,000 capture differently year to year) and does not represent the vendor's actual enterprise workforce or federal revenue. SCI's median government-paid hourly rate on prime records is $155.54 per hour, derived from the single FY2023 invoice, and is not representative of the vendor's full rate structure across its larger delivery-order portfolio.
E2's capability framing centers on environmental remediation, Superfund site support, hazardous-waste engineering, and water-infrastructure oversight under primary NAICS 541620 (Remediation Services), which covers 37 of 45 awards. The corporate structure includes two subsidiaries: E2 Consulting Engineers Inc. and E2 Federal Services LLC, both minority-owned entities, though the source does not indicate differentiated capability or customer routing between parent and subsidiaries.
