Ajax Building Corporation to Join the Structure Tone Organization

New York, NY/Midway, FL (October 17, 2018) – Ajax Building Corporation announced today that the firm has joined the Structure Tone family of companies. The move allows Ajax to access Structure Tone’s global network and resources and expands Structure Tone’s reach into the Southeast US.

“Partnering with a firm that shares our culture and values is an ideal way to continue fostering the growth we’ve seen over the past 60 years, while still offering the same client-focused approach that has allowed Ajax Building Corporation to become established leaders in construction management,” says Bill Byrne, president of Ajax Building Corporation.

Founded in 1958, Ajax Building Corporation has steadily built a reputation as a construction management leader in the Southeastern US. With over 200 employees in locations across Florida and Georgia, as well as operations in South Carolina, the firm is one of the fastest-growing construction firms in the area, covering a mix of both ground-up and interior construction projects across a diverse range from K-12 and higher education, to city, county and state government, to healthcare and historic restorations.

“Ajax Building Corporation is a leader in one of the fastest-growing markets in the US,” says Structure Tone CEO Robert Mullen. “By joining forces, both of our firms are now able to enhance and expand each other’s businesses, clients and service offerings into new areas.”

Last year Structure Tone restructured its ownership model to extend company ownership to all employees and a small group of outside investors. This private ownership model will now extend to Ajax employees as well.

“As we celebrate Ajax Building Corporation’s 60th anniversary, I am excited that this partnership offers ownership opportunities in the company my family began to those who have become our extended family: our employees,” says Jay Smith, vice president of Ajax Building Corporation. “For our employees, clients and new Structure Tone partners, Bill and I have made long-term commitments to continue leading Ajax as we move forward into the future.”

“This addition of Ajax is a continuation of Structure Tone’s mission to expand construction services to our growing global client base while remaining committed to our core values, which has made us one of the top construction management firms in the business,” says Structure Tone executive chairman James Donaghy. “It also opens up new avenues for employees from both firms to grow and develop their careers.”

Ajax Building Corporation will retain its name, and its current leaders—Bill Byrne and Jay Smith—will retain ownership in the company and maintain their roles as the senior leadership team of the business. No personnel changes are expected for either company.
