Designing for Performance, Efficiency, and Comfort 

H2M’s MEP solutions place an emphasis on building performance, energy efficiency, and occupant comfort. Although their work may be hidden in ceilings, behind walls, and under floors, H2M’s mechanical, electrical, plumbing, and fire protection engineers treat it like the main event. While their efforts might not be visible in the finished product, the effortlessness they bring to your building’s operations will be. 

Focusing on developing detailed quality drawings, H2M will meet each client to establish the full scope of work before putting pen to paper.  By spending time in the field, taking measurements, and asking the right questions, H2M ensures a level of detail that simplifies the bid and construction process as well as the results in fewer change orders.
