Relationships and technical excellence

Calder Richards was founded in 2005 through the merger of two of Utah’s leading structural engineering firms—Calder Kankainen Consulting Engineers and Richards Consulting Group, each established in 1986. From engineering for the 2002 Winter Olympics to seismically upgrading Utah’s iconic historic buildings, we carry forward our founders’ commitment to lasting relationships and technical excellence.

We do big projects, and we do small projects in a big way. Whatever the scope, we deliver cost efficiencies through smart engineering design—without compromising the vision, goals, or sustainability of any project.
