10-4 Engineering, PLLC

10-4 Engineering is a Chicago-based civil/structural engineering firm recently founded by three licensed structural engineers: Hemal Patel, Gary Powell and Vinod Patel. Hemal, Gary and Vinod have a combined 100 years of experience in bridge inspections and bridge design engineering through delivering large and complex infrastructure projects, such as highway corridors, interchanges, public-transit networks, and river crossings. Many of their projects have been award-winning designs recognized by the clients and the industry.

We focus on bridge design and inspection (roads/highways and rail/transit), providing the supporting structural reports, calculations and drawings.

Our name, 10-4 Engineering, is derived from the widely used term "10-4," which signifies “message received, taking action”. Similarly, we embody the principles of direct communication and decisive action in designing infrastructure. Besides technical competence, we place a high value on these two principles when it comes to successful project execution and delivery. Welcome to a place where every challenge is met with a resounding "10-4".
