Our experienced and qualified team of mechanical engineers delivers thoughtful, integrated designs that are energy-efficient, cost-effective, and easy to maintain. In addition to system design for a wide range of building types, our services include life cycle cost analysis, system investigation and trouble shooting, facility condition assessments, energy studies, commissioning support, and the design of heating and cooling infrastructure such as central utility plants.
We provide both 2D and 3D drawings, along with comprehensive graphical and non-graphical design information. This includes BIM services and energy modeling, delivered at any stage of the project lifecycle—from initial concept through design, construction, commissioning, and beyond.
Our mechanical engineering deliverables include heat load calculations, floor plans, schedules, system diagrams, and detailed equipment specifications.
