Galloway & Company, LLC, a national architecture and engineering firm based in Denver, announced today the acquisition of Z Development Services, a Florida-based civil engineering firm, on April 10, 2026.
“The addition of Z Development Services supports Galloway’s continued national growth, and it enhances the resources we can bring to clients across the country,” said Galloway President Dave Guetig, PE. “Just as important, Z Development’s people-first mindset and commitment to client service strongly align with our culture, so we are excited to welcome them to Galloway.”
Z Development Services brings a strong track record in civil engineering and development-related services across the United States. Their capabilities include due diligence, civil engineering design, and project management support through design, permitting, and development. The Z Development Services team will continue to operate from Orlando and maintain continuity for clients while expanding access to Galloway’s additional multidisciplinary resources.
“Joining Galloway is a natural fit because their values and commitment to client success reflect our own,” said Bob Ziegenfuss, PE, founder and president of Z Development Services. “By uniting our teams, we significantly enhance our collective skillset, allowing us to expand our regional and national influence while delivering even greater opportunities and innovative solutions for our clients.”
This acquisition aligns with Galloway’s long-term growth strategy and is supported by their investment partners, ARA Services Partners and Kelso & Company.
We are nationally recognized and locally preferred. We would love to work with you on your next project.
