David Chen

Midwest Development Partners

Ironclad has been our go-to structural engineering firm for 8 years. Their steel connection designs are always buildable, and Mike Walsh personally reviews every set of drawings. Excellent coordination with our steel fabricators. Can't recommend them highly enough.

Jennifer Torres

Torres Architecture + Design

We had a challenging adaptive reuse project converting a 1920s warehouse to loft apartments. Ironclad's structural assessment was thorough, and they developed creative solutions for maintaining the historic character while meeting seismic code. Sarah Kim was exceptional to work with.

Solid structural engineering work on our industrial warehouse expansion. RFIs were answered quickly and their special inspections team kept the project on schedule. Would use again for our next project.
