Mazzetti and CDi Engineers Merge, Creating a Powerhouse of LEAN, Energy-Efficient Engineering


On May 1, Seattle-based CDi Engineers merged with Mazzetti’s nine national offices to form a strengthened firm delivering innovative engineering in healthcare, higher education, mission critical, science and technology, aviation, and other sectors.

Mazzetti and CDi Engineers (CDi) are both seasoned firms known for their industry leadership in research and policy, planning, finance, and project delivery. Both firms have worked to drive the future of the built environment in their work with the Facilities Guidelines Institute (FGI), American Society for Healthcare Engineering (ASHE), and American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), among other organizations.

“We are incredibly excited to be joining forces with such a like-minded firm. Together we can provide more value to our clients through increased services, expertise, and geographic reach,” said Dick Moeller, President of CDi Engineers. “At the same time, given our closely aligned operations and culture, our current clients can continue to enjoy the same high-quality service with the same great staff.”

CDi was founded in 1988 and has served clients, such as the University of Washington, the Port of Seattle, the Washington Trade and Convention Center, as well as a significant number of healthcare providers, including Swedish and Providence, Legacy Health, and Catholic Health Services. The 35-person firm has become an industry expert and leader in LEAN and sustainability engineering, and is known for their award-winning work in healthcare, higher education, aviation, performing arts, and institutional design.

“I have worked for many years with Dick Moeller from CDI on the FGI Guidelines, ASHRAE committees, and with ASHE. Through this, I developed a strong admiration for Dick and, indirectly, for his firm and its work,” said Walt Vernon, President and CEO of Mazzetti. “Now that I have gotten to know the people at CDi, I am even more impressed by who they are, and with what Dick and his partners have created. I am so happy to put together our two firms because we share the vision of making the world a better place by creating better environments, and because I know that we can do it better together than either of us could do it apart.”

The combined firm will have $32 million in gross revenues, with 170employees, which will place it among the largest MEPT engineering firms in the country.

Mazzetti’s new Seattle office will expand from mechanical only to a complete MEPT firm, offering services in mechanical, electrical, plumbing, technology, equipment planning, sustainability, and commissioning. The office will take on the brand CDi + Mazzetti until May 1, 2015, when it will be branded Mazzetti.
