Our firm was started in 2001 by Mark A. Day, PE after branching out on his own. In 2019, Mark took on a partner, Brian J. Stokosa, PE. We are a mid-sized firm specializing in all aspects of design drafting, civil engineering, and structural engineering.

Our firm’s top priority is understanding the client’s needs and fulfilling them from the very first meeting through to project completion. We pride ourselves on our ability to understand the end goal and see it through our client’s eyes and perspective. We provide professional services with a proven track record as much of our business is from referrals or repeat clients.
