What Driesenga & Associates does

Driesenga & Associates, Inc. (D&A) is a Michigan-based, privately held civil engineering firm founded in 1995 by Dan Driesenga in Holland, Michigan, and led since 2019 by President Jim Henning. The firm delivers an integrated suite of professional services across Civil Engineering, Geotechnical Engineering, Environmental Consulting, Land Surveying & Construction Staking, and Materials Testing & Inspection. Project work spans feasibility and site planning through design, permitting, and construction-phase inspection, with in-house laboratory capabilities covering soil gradation, permeability, concrete and asphalt mix-design, Marshall density, and concrete compressive/flexural strength testing.

The firm holds Michigan Department of Transportation (MDOT) pre-qualification for materials testing and surveying, supplemented by MCA, ICC, and ACI technician certifications, enabling access to state-funded infrastructure projects. Field operations are supported by robotic total stations with electronic data collectors integrated with CAD drafting, GPS-enabled surveying, and five physical offices across Michigan: Holland (headquarters), Grand Rapids, Kalamazoo, Lansing (opened 2020), and Ypsilanti. The firm previously operated in Indiana and North Carolina but exited those markets in 2009 during the Great Recession to focus on core Michigan clients.

D&A generates revenue through project-based professional services billing, primarily time-and-materials or fixed-fee engagements quoted per scope of work, sold via direct sales to enterprise clients (national retailers like ALDI and Chick-fil-A, industrial firms including Gentex, Coastal Container, and King Milling, and healthcare and education institutions), mid-market developers, construction contractors, and municipal/government agencies. Distribution relies on five regional offices, a "Request A Quote" website channel, and relationship-driven referrals within the Michigan construction and development community, with limited digital marketing presence beyond LinkedIn and Facebook. The firm is privately held, with no external investors or parent company disclosed, and an estimated 11-50 employees.
