About Tidewater, Inc.

Written by GovTribe AI ·

Tidewater, Inc., a minority-owned, self-certified small disadvantaged business headquartered in Elkridge, Maryland, operates as a prime contractor delivering facility maintenance, infrastructure sustainment, environmental remediation, and specialized technical support services to federal agencies. The company is structured as a Subchapter S Corporation with Subcontinent Asian American ownership and carries DOT Disadvantaged Business Enterprise certification. Tidewater competes predominantly in full-and-open procurements (100% of recent awards are prime work) and holds a $999.999 billion OASIS+ Total Small Business multiple-award contract with GSA, a $210 million Medical Facilities Support Services IDIQ with the Army Corps of Engineers, and multiple smaller fuel systems maintenance IDIQs with the Department of State, positioning it as a significant federal infrastructure and facilities provider.

Tidewater's customer base is highly concentrated by agency and geography. The Department of the Army Corps of Engineers Engineering District Charleston dominates activity volume with 622 awards and $124.8 million in combined potential value, followed by the Department of State Bureau of Overseas Building Operations (229 awards, $327.8 million potential value), though potential value rankings flip when large vehicles are included—the Air Force Civil Engineer Center leads by dollars at $3.5 billion across 12 awards, primarily driven by the OASIS+ vehicle. The top five customers by award count represent 51% of all awards; the top five by potential value represent 15% of total potential value combined. This signals a portfolio heavily populated by small-dollar task orders from USACE Charleston interspersed with larger construction and design-build awards from the State Department and Navy.

Tidewater's capability portfolio centers on facility operations and maintenance. Named work includes fuel management system maintenance and repair at overseas diplomatic facilities in Kosovo, Tajikistan, Guinea, Kenya, Mali, Egypt, Ukraine, Brazil, Netherlands, Mongolia, Mexico, Fiji, South Africa, Indonesia, Ethiopia, Brunei, and Pakistan; building infrastructure sustainment at military installations (flooring replacement, door and window replacement, HVAC repair, boiler replacement, concrete pad installation, electrical work, plumbing, fire alarm systems); environmental investigation and radiological surveys (historical site assessments at the Boiling Nuclear Superheater reactor facility in Puerto Rico, contamination surveys at VA facilities, underground storage tank closure at Fort Meade); and design-build construction services for overseas embassy improvements in Brazil and the Netherlands. Representative awards include a $6.27 million delivery order for U.S. Embassy Managua consular affairs renovation under the State Department's $150 million Worldwide Design-Build Construction and Projects IDIQ, a $4.45 million historical site assessment and site characterization order at the BONUS reactor facility under the Department of Energy, a $7.3 million delivery order for emergency power to IT cooling equipment at Walter Reed National Military Medical Center under the Navy's Bureau of Medicine and Surgery, a $4.576 million IDIQ for 81st Readiness Division facility investment services under Army Corps of Engineers Charleston District (total small business set-aside through November 2029), and hundreds of smaller $10,000–$300,000 task orders for facility repairs at military installations and diplomatic posts.

The OASIS+ Small Business vehicle, awarded December 19, 2024, through December 18, 2029, carries a $999.999 billion ceiling (a GSA placeholder indicating no specified cap) and covers seven functional domains: Management and Advisory, Technical and Engineering, Research and Development, Intelligence Services, Environmental Services, Facilities, and Logistics. Tidewater's GSA Multiple Award Schedule contract (effective August 15, 2025, through August 14, 2030, with a $475 thousand ceiling) offers 56 labor categories at rates from $41.47/hr (Laborer, high school, three years experience) to $242.33/hr (Principal, master's degree, fifteen years experience), spanning HVAC, plumbing, electrical, project management, environmental consulting, and radiological assessment roles. No security-cleared positions are offered. The Medical Facilities Support Services IIIB IDIQ ($210 million multiple-award vehicle through February 20, 2031) funds operations at Defense Health Agency medical facilities outside the contiguous United States, including Bahrain, Belgium, Germany, and Japan; Tidewater delivered a $6.6 million delivery order for Naval Hospital Yokosuka facility support operations through August 30, 2031.

Activity peaked at 144 awards in 2023, declined to 81 in 2024, and has dropped sharply to 57 in 2025 and 12 in 2026 year-to-date, signaling either a slowing in new task order volume or a timing shift in award data collection. The recompete cliff presents 28 awards with ultimate completion dates in the next twenty-four months and combined potential value of $32 million.

Service Contract Inventory data (FY2022–FY2024, prime records) shows $3.6 million in invoiced revenue across 23 contracts, dropping from $3 million in FY2023 to zero in FY2024; SCI-reported FTE delivery ranged from 4.6 FTEs (FY2023) to 11.2 FTEs (FY2022). Government-paid median hourly rates on SCI-reportable prime contracts ran around $672.70/hr, with the 90th percentile at $2,213.73/hr, reflecting a portfolio mixing entry-level labor (10th percentile $15.64/hr) with senior technical and program management delivery. Tidewater performs zero average subcontractor hours across prime service contracts, indicating the vendor builds its own delivery teams rather than leveraging subs for SCI-reportable work.

Tidewater operates six named subsidiaries, including Vets-Tidewater LLC (service-disabled veteran-owned), Tidewater-Usa JV LLC and Tidewater-PHE JV LLC (small business joint ventures), and Tidewater-Sovereign Consulting JV LLC (minority-owned, small disadvantaged business joint venture), enabling the parent to pursue joint venture opportunities while preserving distinct certifications and ownership designations across the corporate family.
