What Tidewater does
Tidewater, Inc. is a privately held environmental and infrastructure services provider founded in 1983 in Baltimore, Maryland, and now headquartered in Elkridge, Maryland. The company operates through three service divisions — Environmental (since 1994), Construction, and Facilities (since 2006) — employing 140+ personnel across two product lines and delivering work in all 50 U.S. states and over 100 countries. Its technical capabilities span environmental remediation under CERCLA, RCRA, and State/Local UST frameworks (including emerging contaminants such as PFAS, 1,2,3-trichloropropane, and 1,4-dioxane), radiological services supported by four nationwide reciprocal NRC radioactive materials licenses, direct-push drilling using three Geoprobe rigs with SCP/MIP/LIF probe tooling, industrial hygiene, design-build and design-bid-build construction, secure-space/SCIF work, and facility maintenance across 150+ locations covering more than 5 million square feet.
The company generates revenue exclusively through professional services contracts awarded by federal, state, and municipal government clients, primarily the U.S. Department of Defense (Navy, Army, Air Force, Marines), Department of State, USACE, NAVFAC, GSA, NASA, and HUD. Pricing is determined per contract vehicle and task order with no publicly disclosed standard pricing. Tidewater pursues work through more than 30 federal contract vehicles, including GSA Environmental/Facilities/Construction Schedules, NAVFAC Southeast ETS and SB-MACC, multiple USACE district MATOCs and SATOCs (Baltimore, Buffalo, Charleston, Fort Worth, Huntsville, Kansas City, Los Angeles, Rock Island, Sacramento), and Department of State worldwide environmental and construction IDIQs. Notable engagements include the DoS International Maintenance Assistance Program (IMAP) covering 130+ embassies/consulates in 125+ countries since October 2018, fuel and water systems support at 60+ U.S. diplomatic compounds since 2007, and medical facility support at Walter Reed National Military Medical Center.
The company is an SBA 8(a) Program graduate (entered 2004) and a small disadvantaged business, holding $25 million single / $75 million aggregate bonding capacity through Great Midwestern, plus active security clearances enabling work in classified spaces. Leadership is led by President and CEO Prasad Dissanayake, PE, supported by five Vice Presidents heading the Environmental, Construction, Facilities, Radiological, and Product Line Integration functions. The ownership structure appears to be founder/management-owned with no disclosed private equity or parent company involvement. The company has received the 2016 DoS OBO Small Business of the Year and the 2011 Nunn-Perry Award.
