Industries we serve

We go where the project is complex.

Architects call 4b when precision matters most. We’ve spent 25 years earning that call.

Airports, terminals, and airside facilities designed for operational excellence.

“I have had the pleasure of working with 4b for the past 13 years as both an owner at the University of Houston and now as a client at Shepley Bulfinch. The thing that I value the most is the wealth of institutional experience for a given client that they bring to the table so that we can immediately get off the ground and not lose time learning the client’s standards. I look forward many more projects with 4b.”
