T&M Associates

What T&M Associates does

T&M Associates is a private, multidisciplinary engineering and technical services firm headquartered in Middletown, New Jersey, founded in 1966 as a seven-person practice and grown to 375+ professionals operating from 17 offices across the United States. The firm is organized around five service markets — Buildings & Facilities, Community & Land Development, Environmental, Transportation, and Water — delivering design, permitting, construction administration, and inspection services to public and private clients. Government work spans municipal, county, and state agencies (notably NJDOT, NJ Turnpike Authority, NJDEP-regulated utilities, and Port Authority of NY & NJ) as well as federal clients (US Air Force, FEMA); private clients include water utilities such as Middlesex Water and Veolia, developers such as Boston Properties, and corporates such as Cummins.

Service delivery is project-based and custom-scoped, with revenue generated through professional services engagements billed against defined scopes rather than standardized pricing. Differentiated technical capabilities include the first ion-exchange (IX) resin PFAS treatment system for municipal drinking water permitted by NJDEP (co-developed with ECT2), green stormwater infrastructure and hydraulic/hydrologic modeling, SCADA/PLC automation for groundwater treatment (including US Air Force work), and bridge inspection and construction administration for state DOT and county clients. The firm pursues long-tenured relationships — exemplified by 15+ years with Northwest Bergen County Utilities Authority — and reinvests in the community through the T&M Foundation, a 501(c)(3) established in 2021.

The go-to-market motion is sales-led, relying on direct engagement with government procurement and private clients, formal competitive bidding for public-sector work, and brand credibility built through ENR analyst rankings (Top 500 #258, East #58, Midwest #73, Environmental #174) and regional industry awards. The company is self-funded and founder/management-owned, with CEO Gary Dahms in his 40th year and a recent CFO hire (Adanma Akujieze) signaling a professionalization of the finance function to support continued scaling.

• GAI Consultants: Mid-size engineering and environmental consulting firm with similar practice areas (transportation, water, environmental, community development). Comparable to T&M in scale, public-sector orientation, and Mid-Atlantic presence.
• Michael Baker International: U.S. engineering, planning, and consulting firm with deep practices in transportation, water, environmental, and federal infrastructure. Comparable to T&M in serving DOTs, transit authorities, and federal clients, though larger and PE-backed.
• Kimley-Horn: Large privately held U.S. engineering consulting firm offering planning, design, and environmental services across similar practice areas (transportation, water, environmental, land development). Closely comparable to T&M in being private, employee-centric, multi-disciplinary, and ranking in the top tier of ENR design firms.
• Remington & Vernick Engineers: Northeast-based civil and environmental engineering firm serving municipal, county, and state clients with comparable water, transportation, and site development services. Closely matches T&M's NJ/Mid-Atlantic orientation and public-sector mix.

Emerging players

• NV5 Global: Technical engineering and consulting firm with infrastructure, environmental, and geospatial practices that compete with T&M on similar public-sector projects. Public company with acquisition-driven growth strategy provides useful contrast to T&M's organic-only model.

• Tetra Tech: Engineering and consulting firm with deep environmental and water practices serving federal, state, and municipal clients. Directly comparable to T&M's environmental and water services but at significantly larger scale.
• AECOM: Global infrastructure consulting firm with major U.S. presence in water, transportation, and environmental engineering. Competes with T&M on larger public-sector pursuits and federal contracts, with substantially greater scale and resources.
• Jacobs Solutions: Global professional services firm with major infrastructure and water practices serving public-sector clients. Comparable to T&M in core service areas but operates at vastly larger scale with national and federal program capabilities.
