Green International Affiliates

What Green International Affiliates does

Green International Affiliates, Inc. is a U.S. transportation and infrastructure engineering consultancy that provides work order-based engineering and design services to government transportation agencies. Its core services span roadway and intersection design, traffic engineering, park and ride facility design, rest area design, and transportation safety engineering, primarily serving the Vermont Agency of Transportation (VTrans) under a retainer contract model that has been renewed consecutively since 1999.

The company operates as a subsidiary of H.W. Lochner following a January 2025 acquisition, and is itself part of the broader Egis U.S. portfolio of infrastructure engineering firms, which collectively employs 1,400+ people across 22 states and ranks #56 on the ENR Top 500 Design Firms. Through this integration, Green International Affiliates gains access to multidisciplinary capabilities across planning, environmental services, design, construction engineering and inspection, and program management.

Commercially, the firm generates revenue through professional services contracts — specifically retainer and work order arrangements — with state and municipal government clients. Pricing is quote-based and determined per work order rather than through standardized public pricing. Geographic focus has historically been Vermont and New England, but post-acquisition the company is actively developing water and municipal infrastructure services across the broader Northeast, supported by parent-level investments in water and environment leadership hires. No AI, proprietary software platform, or subscription product was disclosed in the source material; the business remains a traditional professional services engineering firm.

Direct peers

• WSP USA: WSP's U.S. operations include a large transportation infrastructure practice providing planning, design, and program management for state DOTs and authorities. It directly competes with Green International on Northeast transportation RFPs and shares expertise across highway, bridge, and transit modalities.
• Stantec: Stantec is a global engineering consulting firm with a substantial U.S. transportation infrastructure practice serving state DOTs on roadway, bridge, traffic, and multimodal projects. It directly competes with Green International and the broader Egis/Lochner platform for state DOT retainer and design contracts.
• Kimley-Horn: Kimley-Horn is one of the largest U.S.-based transportation engineering consultancies, providing roadway, traffic, and infrastructure design to state and municipal clients nationwide. Its private, employee-owned structure mirrors Green International's professional services DNA, and it competes for the same DOT design contracts.
• HDR: HDR is a major employee-owned engineering firm with deep transportation, highway, bridge, and water practices serving state DOTs and municipal clients across the U.S. It is a direct peer for the same roadway, traffic, and multimodal design work Green International performs.
• VHB: VHB is a Northeast-based engineering, planning, and design firm of comparable size specializing in transportation, land development, and environmental services for state DOTs and municipalities. It is the closest like-for-like peer to Green International in scale, geography (New England), and transportation engineering focus.
• Michael Baker International: Michael Baker International is a major infrastructure engineering consultancy with practices in highways, bridges, traffic, and water serving public-sector clients nationwide. It competes for the same state DOT retainer and design work as Green International and the Egis/Lochner platform.
• TranSystems: TranSystems is a transportation-focused engineering and planning consultancy serving state DOTs, railroads, and agencies with roadway, bridge, and traffic engineering services. Its mid-size, transportation-pure focus makes it a strong comparable to Green International's specialist profile.

Broad incumbents

• Jacobs: Jacobs is a global professional services firm with significant transportation, water, and infrastructure design practices serving state DOTs, transit agencies, and municipal clients. It competes with Green International on transportation design but at much greater scale and scope across multiple verticals.
• AECOM: AECOM is a global infrastructure consulting firm with a very large U.S. transportation practice spanning highways, bridges, transit, and program management for state DOTs and federal agencies. As a much larger incumbent, it competes broadly with Green International's service lines but offers far greater scale and alternative delivery capability.
• Mott MacDonald: Mott MacDonald is a global engineering consultancy with a sizable U.S. transportation practice delivering highway, bridge, transit, and tunnel projects to public agencies. It is comparable to Green International on the transportation design side but operates at a much larger scale and broader geographic footprint.
