Rooftop HVAC unit (RTU) installations involve both mechanical engineering — for equipment sizing, duct connections, and energy compliance — and structural engineering for the roof framing capacity and equipment anchorage. Apex Grid coordinates mechanical and structural RTU engineering under one engagement, eliminating the coordination gap between disciplines.
Request Engineering SupportApex Grid Engineering is a multi-discipline firm with multi-state PE coverage confirmed per project. We provide rooftop hvac unit engineering as a standalone service or coordinated with structural, MEP, civil, and geotechnical engineering under one contract. Our engineers produce PE-stamped permit packages that building departments accept — and we respond to plan check comments as part of the scope.
