The Structure Tone Building Group Moves Up Two Spots on the ENR 2019 Top Contractor List

We are so proud to be part of the Structure ToneGo to Building Group family, who moved up two spots this year to the #14 ranked contractor in the country!

In 2018, many contractors made moves to expand or enhance their offerings. Many other contractors have gone the acquisition route recently. Structure Tone added Canada’s Govan Brown to enable it to work throughout that country and with a new portfolio of clients, while the firm’s purchase of Florida-based Ajax Building Corp. expands its reach into public facilities and into the U.S. Southeast region. Structure Tone now has rebranded itself as STO Building Group Inc. With that expanding platform, “we expect to see even more opportunities to enter new markets—both in geography and market sectors—in the coming years,” says Bob Mullen, CEO of STO Building Group.”
