Why Hennessey

For nearly 50 years, Hennessey has thrived in providing quality, cost-effective design solutions in all aspects of civil engineering for numerous Southeast Michigan communities. Our work spans from private to public sectors, including projects for municipalities, counties, and state agencies. The culture at Hennessey keeps us nimble and able to maintain an impressive list of clients — some of which we’ve been serving for nearly 40 years. When you invest in the Hennessey team, we are invested in you. We offer personalized service with a community focus to deliver superior solutions.

Personalized Service
Hennessey personalizes its services for each unique client. Exclusively serving Southeast Michigan, our team is a unique blend of experienced support staff that efficiently responds to project and client needs. Many of our team members are residents of the communities we serve. We understand the local landscape and offer a variety of professional engineering services, and beyond.

In addition to civil engineering, Hennessey’s licensed professionals provide surveying, architectural design, construction administration, construction inspection, quality control and quality assurance testing, and geographic information system management. We also operate a soils/materials laboratory which enables us to oversee the testing facet of a project from within our organization. We can perform field quality control tests, as well as laboratory tests on soils, aggregate, asphalt, and other construction materials.

The firm’s most distinctive service offering is program management where we help communities secure funding for infrastructure, enhanced mobility, and economic development. To date, our team has captured $75 million of county, state, and federal grants and MDEQ low-interest loans.

Community Focus
With municipal engineering at the core of our business, we understand the challenges facing communities in Southeast Michigan. Partnering with our clients and their residents, we listen and respond by serving as an extension of their voices before delivering the very best solutions. We have established an excellent relationship with local utility authorities in addition to County and State governmental agencies, and we are acclimated to their standards and guidelines.

Superior Solutions
Often, our solutions start before conceptual planning even begins. By helping communities identify and obtain project funding, we make community-wide projects possible. Our diverse team of professional engineers, surveyors, and construction administration specialists then work collaboratively to deliver well-planned and expertly designed solutions, and in a timely fashion. Because our company is small to mid-size in scale, we have smaller overhead costs as compared to much larger firms, allowing us to pass cost savings on to our clients.

At Hennessey, our engineering solutions produce remarkable results. Ultimately, our goal is to enhance the Southeast Michigan experience, making each community a desirable place to live.
