What EMH&T does

EMH&T (legal name: Evans, Mechwart, Hambleton & Tilton, Inc.) is a privately held civil engineering consulting firm headquartered at 5500 New Albany Road, Columbus, Ohio. Founded in 1926 as a small land survey firm, it has grown over a century into a multidisciplinary practice delivering site development, urban revitalization, planning and landscape architecture, transportation engineering, utilities, water resources and stormwater management, land surveying, construction services, environmental sciences, cultural resources, 3D visualization, geospatial/GIS solutions, and energy and telecommunications engineering. The firm operates across at least 13 service lines under one roof and supports a wholly-owned infrastructure evaluation division called Infratechnologies. Its technology stack is built on standard AEC industry tools including AutoCAD Civil 3D, MicroStation, OpenRoads Designer, GEOPAK, Trimble GPS/GNSS, robotic total stations, and 3D scanning.

EMH&T serves both public sector clients (local, state, and federal government agencies including ODOT, the City of Whitehall, and the City of Dublin) and private sector clients (commercial developers, industrial and logistics firms, healthcare systems, higher education institutions, railroads such as CSX, and utilities/energy companies). The firm's revenue model is professional services: project-based fees, hourly billing for professional staff, and multi-year contract engagements, with no publicly disclosed pricing. GTM motion is relationship-driven enterprise field sales, with work won through qualifications-based selection, competitive bidding/RFPs for government work, and direct negotiation for private engagements. Long-tenure anchors include a partnership with Easton Town Center developers dating to 1994 and an active ODOT/ACEC-recognized collaboration on the Worthington Northeast Gateway project.

The firm markets itself through its semi-annual Ingenium magazine (distributed to 1,300 public sector clients), industry conferences (Ohio Transportation Engineering Conference, Ohio Stormwater Conference), university recruiting at Ohio State and other Ohio institutions, and community engagement (Mid-Ohio Food Collective structured giving program). EMH&T has received multiple awards including #1 Central Ohio engineering firm (Columbus Business First, 2026), #1 Extra-Large Best Places to Work (Columbus Business First, 2024), Top Workplaces USA (2022), and several ACEC and Ohio Parks and Recreation Association project awards. The firm is led by President Sandy Doyle-Ahern, Executive Vice President and COO Doug Romer, and CFO Ken Shoemaker, and is celebrating its centennial in 2026.
