What RHEA does

Rhea Engineers & Consultants, Inc. is a 100% woman-owned professional engineering and consulting corporation founded in 2001 and headquartered in Moon Township, Pennsylvania (Pittsburgh metro). The firm provides eight discrete service lines covering civil site development, environmental services, geotechnical engineering, water resources engineering, land surveying and mapping, field monitoring and management, cultural resources management, and geophysics. Its technology stack combines non-invasive subsurface investigation methods (ground-penetrating radar, EM-38 electrical conductivity surveys, electromagnetic surveys), specialized remediation techniques (ozone injection achieving up to 80% contaminant reduction, TC-341 free-phase product recovery with surfactant injection), and mainstream engineering software (Bentley InRoads, HydroCAD, AES StormTech, CADD/GIS) for stormwater modeling and infrastructure design.

The company serves federal, state, and municipal government clients alongside commercial and institutional customers across six verticals: Aviation, Transportation, Federal Government, Commercial + Industrial, Public + Institutional, and Energy + Utilities. Named federal customers include the U.S. Navy (NAVFAC contracts at MCB Camp Lejeune, MCAS Cherry Point, Naval Support Activity Bethesda, Joint Base Anacostia-Bolling), U.S. Army Corps of Engineers, FAA, and the Allegheny County Airport Authority; municipal and institutional clients include McCandless Township, Alexandria Archaeology, the Urban Redevelopment Authority of Pittsburgh, and various state DOTs in PA, NC, VA, WV, SC, MD, and OH.

Rhea generates revenue through project-based professional services contracts (fixed-price and time-and-materials), with 75% of work sourced from repeat customers. Distribution is anchored in direct enterprise sales to federal agencies via GSA Schedule contracts (899 1 and 541620), state DOT DBE set-aside contracts, and three active joint ventures (Rhea-GPI with Greenman-Pedersen, Inc.; Rhea-Davenport World; and AMS-Rhea) that extend reach into remediation O&M, radon assessment, and integrated geospatial/surveying services. Headcount is reported in the 11-50 range. The firm holds WBE, WOSB, DBE, SWaM, SBD, and SDB certifications across federal and state levels, providing preferential access to set-aside contracts.
