PEER

What PEER does

PEER Consultants, P.C. is a Washington, D.C.-headquartered environmental engineering consulting firm founded in 1978 by Dr. Lilia A. Abron, operating across four U.S. offices (Washington DC, Baltimore, Burlington MA, Stafford VA) with 70+ engineers, scientists, planners, and technicians. The firm delivers four integrated service lines: Engineering Services (water/wastewater systems, civil/stormwater, coastal asset protection, renewable energy, construction management); Environmental Services (planning, ASTM Phase I/II site assessments, hazardous waste mitigation, NEPA studies, permitting); Advisory Services (asset management via IBM Maximo and Cityworks EAM, GIS analysis, benchmarking, process improvement); and MRO Products distributed through the Grainger Distributor Alliance Program.

The firm's underlying technology stack combines conventional environmental engineering tools — IBM Maximo and Cityworks for enterprise asset management, ArcGIS Online for spatial analysis — with proprietary methodologies including the iEEECO (Integrated Energy Environment Empowerment Cost-Optimization) framework and the ERGY-10 energy efficiency software. PEER also operates a wholly-owned sister company, PEER Africa (Pty) Ltd., focused on sustainable community development in South Africa.

Revenue is generated primarily through fee-for-service professional engineering contracts awarded via government procurement, where PEER acts as prime contractor or subcontractor. The customer base is overwhelmingly public-sector: federal agencies (NAVFAC, EPA), state agencies (MDOT SHA, MWRA), and local/municipal utilities and authorities (DC Water, WSSC, WMATA, Baltimore DPW, DOEE, DCSEU, DCHA, AlexRenew). Pricing is not publicly disclosed and is determined through competitive bidding and negotiated contract vehicles. PEER is one of the largest Black, female-owned environmental engineering firms in the United States, holding MWBE/CBE certifications across multiple jurisdictions that provide preferential procurement access. The company is privately held with no disclosed external institutional investors and operates under the legal name PEER Consultants, P.C.
