Delivering Our Clients A Distinct Advantage For Better Peace Of Mind

Bowman Engineering & Consulting provides civil engineering services and consulting for primarily public agencies and local government authorities. We focus on transportation and public infrastructure projects with a specialization in construction project management, design, and delivery, from the feasibility and planning stages through start-up and completion.

One of the greatest challenges our clients face is dealing with unforeseeable design and construction problems that may pose a threat to the public’s well-being. With a proven track record working on a diverse array of large-scale projects, we deliver a distinct advantage – the ability to identify, monitor, and mitigate challenges observed on mega projects throughout the years. Our emphasis on planning and constant communication helps mitigate design- and construction-related risks and provide our clients with better peace of mind.
