Soils & Structures

What Soils & Structures does

Soils & Structures is a Michigan-based engineering and consulting firm founded in 1974 that provides integrated geotechnical engineering, structural engineering, construction material testing, AASHTO-accredited laboratory testing, and pavement design services. The firm operates four offices across Michigan (Norton Shores headquarters, Ann Arbor, Traverse City, Rudyard, plus an additional Upper Peninsula location in Negaunee) and maintains owned truck-mounted and all-terrain drill rigs that enable on-site mobilization for difficult sites. Its technical stack centers on Bentley structural software, AutoCAD, and Revit, supplemented by an in-house Steel Detailing Department (established 2012) and an AASHTO-accredited testing laboratory on the Muskegon campus.

The company serves government, commercial, industrial, education, and healthcare clients across Michigan, with marquee engagements including the Mackinac Bridge, Grand Rapids Airport ($135M terminal expansion), Fairlife/Coca-Cola's $650M Coopersville facility, La Colombe's $567M expansion, Daifuku North America's $26M manufacturing facility, and Holland Hospital's $45M Westpark Specialty Center. Soils & Structures holds MDOT pre-qualified service vendor status across construction testing and geotechnical design categories and is licensed in 23+ states, providing regulatory entry barriers that support its public-sector work.

Soils & Structures operates a project-based professional services revenue model with quote-based, project-specific pricing and no public fee schedules. The firm is privately held and family-led (Hohmeyer family holds principal ownership; David Hohmeyer serves as President, Joy Hohmeyer as CFO), with a bootstrapped capital structure and no external investment. GTM motion is direct sales to government agencies, municipalities, commercial developers, and industrial clients, supplemented by industry association participation, an MDOT pre-qualification listing, a project portfolio website, and active social media presence.
