Mechanical Engineers
Serving Northern California
Since 1984

Founded in Oakland, California in 1984 by Gary Hennings and Mel Miyakado, H&M Mechanical Group was established to provide mechanical engineering services. With over 70 years of combined experience between the principals, H&M has considerable experience in a variety of projects. Our services include Heating, Ventilating, and Air Conditioning design, Plumbing design, and Energy Analysis. As an added service, in January 2011, Fire Protection systems were included to provide full design and hydraulic calculation.

H&M's engineering approach is streamlined and fundamental, not elaborate and theoretical. When designing a system, the elements are based on budget, type of occupancy, and energy usage. Incorporating these considerations into the building design is Leadership in Energy and Environmental Design (LEED), Collaborative for High Performance Schools (CHPS), and CalGreen, which have set the parameters for building designs. With LEED Accredited Professional personnel, H&M is familiar with these requirements while working on projects which have gone through this certification process.

H&M strives to be at the forefront of the changes in design technology, enabling us to be a pro active participant in the industry. In 1989, H&M replaced their hand drafting method with the AutoCAD program. Before long, it became apparent to H&M that Building Information Modeling (BIM) would play an important role on future technology in building design. Hence, the Revit BIM platform was integrated into our services.

“Response Time” is an important concept at H&M. Our team is committed to providing superior customer service by working in partnership with architects, owners, and other consulting teams. By responding to all phone inquiries, submittals, and questions appropriately and timely, we aim to generate a high level of satisfaction.
