WSP USA Solutions Inc.

WSP USA Solutions Inc., doing business as Louis Berger US, a foreign-owned infrastructure and environmental consulting firm headquartered in Arlington, Virginia, operates as a prime contractor (96% of recent awards) delivering architect-engineer services, environmental remediation and compliance, infrastructure planning, emergency response support, and construction management to federal agencies across 60 distinct customer organizations with a combined federal contracting footprint of $11.41 billion in potential value.

The company's customer base concentrates heavily on infrastructure and environmental missions. The top five funding agencies by award count account for 56% of awards: the Army Corps of Engineers leads with 95 awards valued at $1.81 billion, followed by the National Park Service (90 awards, $455.1 million), Army European Command (50 awards, $546.3 million), the U.S. Coast Guard (37 awards, $293.1 million), and the USACE Europe District (30 awards, $519.8 million). By potential value, however, USAID dominates the portfolio: five awards through the Bureau for Management totaling $2.93 billion, anchored by international development work. The USACE Pittsburgh district contributes an additional $974 million across 25 awards, and the USACE Middle East district adds $787 million across 6 awards. This divergence signals that while the Corps receives the largest share of transaction volume, USAID and USACE's overseas construction programs drive the largest dollar concentrations.

WSP's capability footprint spans concrete, operationally-grounded service delivery. Recent prime awards illustrate the range: a $81.97 million firm-fixed-price delivery order for 35% design phase services on the Ministry of Defense Headquarters building in Riyadh, Saudi Arabia (USACE Middle East, March 2024); a $20.6 million labor-hours delivery order for hydropower environmental and engineering services to the Federal Energy Regulatory Commission (April 2024); a $4.17 million firm-fixed-price delivery order for Facilities Operations Capability and Utilization Survey across six Air Force installations (USACE South Atlantic Division, September 2025); and multiple $75 million indefinite delivery contracts for Advanced Contract Initiative Temporary Emergency Power across all four geographic quadrants (USACE, January 2024 through December 2026). On environmental remediation, the company holds a $225 million Indefinite Delivery Contract with the USACE Kansas City District for hazardous, toxic, and radioactive waste and environmental services supporting the EPA Superfund program, with delivery orders including a $12.79 million cost-plus-fixed-fee contract for Diamond Alkali OU2 oversight in Newark, New Jersey (EPA Region 2, May 2025), and a $6.09 million remedial design contract for 18 Mile Creek in Lockport, New York (EPA Region 2, March 2025). On disaster response, WSP deployed temporary generator sets in response to hurricanes Helene, Milton, Beryl, and Debby, and tropical storms, with individual delivery orders ranging from hundreds of thousands to $9.47 million (Hurricane Helene Alabama response, September 2024).

Vehicle position anchors WSP's federal business model. The company holds a $999.999 billion OASIS+ Unrestricted government-wide contract (GSA Federal Acquisition Service, December 2024, through December 2029), enabling unrestricted ordering across all federal agencies. The company places 118 task orders under the General Services Administration Multiple Award Schedule for a combined $1.37 billion in potential value, spanning architect-engineer, environmental, and professional services work. Three single-award USACE indefinite delivery contracts for Advanced Contract Initiative Temporary Emergency Power (Quadrants I, II, and III) are each valued at $75 million through December 2026, providing pre-positioned rapid-response capacity for federal disaster operations. The company holds multiple significant USACE regional IDIQ contracts: a $249 million architect-engineering contract with the Seattle District (through July 2032); a $248.4 million contract with the Europe District for military construction services under $500,000 (through May 2030); a $249 million architect-engineer contract with the Mobile District for environmental planning and compliance services (through December 2029); a $94.5 million architect-engineer planning contract with the Europe District for locations across Europe, the Caucasus, and the Middle East (through September 2029); and a $225 million USACE Kansas City District contract for HTRW and environmental remediation (through July 2029). The company also holds a $40 million FHWA technical support services BPA (through September 2029) and participates in the USCG Nationwide Architect & Engineering Services vehicle (2017-2022) with 36 task orders valued at $20.8 million.

Activity trajectory shows volatility reflecting the nature of the contract portfolio. Awards per year grew from 71 in 2022 to 100 in 2024, then contracted to 54 in 2025 and 21 through mid-2026 (incomplete calendar year). This decline reflects the maturing and extended performance of large indefinite delivery contracts rather than loss of customer relationships; the company's most recent award is a $275,372 delivery order from the National Park Service (July 2026). Sixty-nine awards with ultimate completion dates in the next twenty-four months carry a combined potential value of $87.7 million and face recompete risk.

Service Contract Inventory data captures a partial view of federal services work. From FY2022 through FY2024, WSP reported $45 million in SCI-reportable invoiced revenue across 100 prime contracts, with FY2023 representing the peak at $25.1 million invoiced across 251 full-time equivalents. FY2024 declined to $6.9 million across 80 FTEs, a sharp contraction likely reflecting the transition from specific multi-year service contracts to delivery-order-based work under larger IDIQs. Government-paid hourly rates on federal services contracts ranged from a 10th percentile of $45.93/hour (cultural resource analysts, GIS specialists) through a median of $113.48/hour (scientists, geologists, hydrologists, environmental specialists) to a 90th percentile of $199.51/hour (senior architects, industrial hygienists). Across SCI-reportable prime contracts, subcontractors account for an average of 3% of contractor hours, indicating the company builds and performs most delivery using internal staff; only six named subcontractors appear in the SCI dataset. GSA Schedule labor categories span 53 unique roles from cultural resource analyst (bachelor's degree, $43.35/hour) through environmental law specialist ($364.44/hour), with no security-cleared positions offered.

The company operates predominantly in full-and-open competition; no awards carry small-business set-aside designations. Work is concentrated in engineering services (225 awards), environmental consulting (128 awards), and electrical contractors/wiring installation (123 awards) by NAICS category, with architect-engineer general services (126 awards) and special studies/environmental assessments (38 awards) as leading PSC codes. Teaming arrangements are minimal: the company primes 96% of awards and subcontracts to other larger primes on less than 4% of its portfolio, positioning it as a preferred prime for large federal infrastructure and environmental programs rather than as a feeder to other contractors. Recent subcontract work includes archaeological evaluation and identification for Marstel-Day LLC (National Park Service historic preservation projects), facilities and engineering support for BAE Systems Technology Solutions & Services Inc. (Defense agency), and multi-mission dry dock program management for WSM Pacific Siop, a joint venture.

Corporate structure reflects international scope. WSP USA Solutions Inc. is a subsidiary of WSP USA Inc. (parent, New York-based, foreign-owned), with 14 named subsidiary entities including multiple joint ventures (Halff-Mott Macdonald-WSP JV, WSP-Moca Joint Venture, WSP Hdr Joint Venture) that extend the company's service delivery capacity and partner relationships across domestic and international markets.
