New practices and markets drive growth for U.S. engineering and engineering-architecture firms. And firms are getting serious about reducing projects’ carbon footprint.

More than 295 U.S. architecture and architecture-engineering (AE) firms participated in BD+C's 2022 Giants 400 survey. As part of the Giants survey process, participating firms are asked to describe their most impactful firm innovations and noteworthy company moves in the past 12 months. Here is a collection of the most compelling business and project innovations and business moves from the 2022 Architecture Giants.

Faster delivery of buildings isn’t always associated with sustainability benefits or long-term value, but things are changing. An instructive case is in the development of steel structures that not only allow speedier erection times, but also can reduce embodied carbon and create durable, highly resilient building approaches.
