What Wallace Montgomery does

Wallace Montgomery is a privately held civil engineering consultancy (Wallace, Montgomery & Associates, LLP) founded in 1975 and headquartered in Hunt Valley, Maryland, with seven offices spanning Maryland, Pennsylvania, Delaware, and Virginia. The firm delivers transportation infrastructure engineering and construction-management services across eighteen disciplines, including highway and bridge engineering, construction management and inspection, environmental services, GIS and asset management, traffic and transportation planning, transit, water resources, and surveying. It is organized around alternative project delivery methods — Design-Build, Progressive Design-Build, Construction Management At-Risk (CMAR), and P3 — with more than 25 years of practice in these methods. Field operations rely on robotic total stations, GPS, LiDAR scanners, digital levels, and drone-based surveying for accelerated, high-accuracy mapping and inspection.

The firm operates on a professional-services revenue model anchored entirely in B2G contract work. Revenue is generated through competitive bidding on infrastructure projects, on-call consulting contracts, and prime or sub-consultant engagements with state departments of transportation (MDOT/SHA/MDTA, DelDOT, PennDOT, VDOT, DDOT), county DPWs, municipal agencies, and transit authorities (MTA, WMATA). Pricing is project-based and not publicly disclosed. The go-to-market motion is enterprise field sales: direct engagement with public-agency decision makers, RFP response, and relationship-led business development through regional offices. Customer base is concentrated in the Mid-Atlantic region across four states, with virtually no disclosed commercial or private-sector footprint outside government infrastructure.

Ownership is structured as a limited liability partnership with partner-level equity held by long-tenured principals (Mawry, Allen, Borusiewicz, and Millikan as of 2026). The firm has no disclosed parent company, external institutional investors, subsidiaries, or M&A activity; growth has been organic, funded by retained earnings and sequenced through three prior names (James Duffy & Associates, Duffy, Montgomery & Associates, Wallace, Montgomery & Associates) before the current Wallace Montgomery trade name adopted in 2012. Headcount stands at 260+ as stated on the firm's careers page, and the firm has held a place on Engineering News-Record's Top 500 Design Firms since 2015.

Direct peers

• Johnson, Mirmiran & Thompson (JMT): Mid-Atlantic-headquartered transportation engineering consultancy with a similar service portfolio (highways, bridges, traffic, environmental, construction management) and a comparable state DOT client base. JMT is a closely analogous regional competitor for the same RFPs in MD, PA, VA, and DE.
• Whitman, Requardt & Associates (WRA): Baltimore-based multi-disciplinary engineering firm providing transportation, water, environmental, and structural services to government clients across the Mid-Atlantic. Directly competes with Wallace Montgomery for the same state and municipal contracts in Maryland and Virginia.

• Michael Baker International: National engineering consultancy with a strong Mid-Atlantic transportation practice and longstanding DOT relationships. Overlaps with Wallace Montgomery on bridge, highway, and alternative delivery pursuits, though with broader geographic reach and a larger balance sheet.
• Gannett Fleming: National engineering firm with significant Mid-Atlantic operations and a transportation practice focused on highways, transit, and water. Competes with Wallace Montgomery on state DOT design-build and CEI contracts in the same region.
• Kimley-Horn: National planning and engineering consultancy with a growing Mid-Atlantic presence in transportation, traffic, and municipal engineering. An increasingly frequent competitor on state DOT and large-county RFPs in the same geographies Wallace Montgomery serves.

Broad incumbents

• AECOM: Global engineering and infrastructure services firm with a substantial US transportation practice. Competes for the largest alternative-delivery and program-management contracts in the Mid-Atlantic and represents a scale-tier above Wallace Montgomery.
• WSP: Global professional services firm with a large US transportation infrastructure practice following the Parsons Brinckerhoff acquisition. Pursues many of the same large state DOT and transit authority contracts across the Mid-Atlantic.
• Stantec: International engineering, architecture, and environmental services firm with a US transportation practice serving state DOTs and municipalities. An aggregator peer that competes for larger regional programs and has acquired regional firms to expand Mid-Atlantic share.
