St. Paul-based TKDA to buy SJA Architects in Duluth

TKDA said the acquisition will help it pursue projects in Greater Minnesota and northwestern Wisconsin.

St. Paul-based engineering and architecture firm TKDA announced Tuesday that it plans to acquire Duluth-based SJA Architects for an undisclosed sum.

TKDA is among Minnesota's largest engineering firms as well as architectural firms based on billings from its Minnesota offices. Its companywide engineering and architectural billings for its most recently completed fiscal year totaled $20.4 million and $7 million, respectively.

TKDA has designed numerous Twin Cities landmarks, including Como Park's Marjorie McNeely Conservatory and the Interstate 35W St. Anthony Falls Bridge after the collapse.

Meanwhile, SJA Architects has also led several high-profile projects, including several University of Minnesota buildings in both the Duluth and Minneapolis campuses.

TKDA said the acquisition of SJA will strengthen its position in the architectural community and better enable it to pursue projects in Greater Minnesota and northwestern Wisconsin. The acquisition will also expand TKDA's staff from roughly 190 to about 200.

TKDA said that SJA's 10 employees will remain in Duluth, and it expects to add engineering staff to the Duluth location in the months to come.

“We want to create the best team to win additional work and are committed to maintaining and growing the Duluth office,” TKDA CEO Bill Deitner said in a statement. “With our combined expertise, services, and dedication to our clients and communities, we expect our partnership will lead to future growth and additional projects for the firm.”

In addition to its St. Paul headquarters and the newly acquired Duluth office, TKDA has offices in Chicago; Tampa, Florida; Irvine, California; and Kansas City, Kansas.
