Rooftop HVAC
Package units, condensers and air handlers on curbs or sleepers, into wood, steel or concrete roofs.
Equipment anchorage
Anchorage traced all the way to the structure.
Seismic and wind anchorage for equipment on roofs, pads and floors, with the anchors, curbs and sleepers designed and the load followed into the framing or the slab that carries it.
Equipment
What we anchor.
Electrical equipment
Switchgear, panelboards, transformers and inverters on pads, floors and walls.
Generators and tanks
Generators, fuel tanks and skids, with the anchors and the pad checked.
Battery storage
Battery energy storage systems and their pads, with the manufacturer's anchor layout checked.
EV charging
Chargers and the equipment that feeds them.
Pipe racks and supports
Racks, frames and supports for piping and conduit.
What you get
From the force to the framing.
- Seismic forces on the equipment and wind on rooftop units, by the current building code
- Anchors in concrete designed to ACI 318 Chapter 17; screws and lags into wood and steel
- Curbs, sleepers and attachments designed, not assumed
- The existing roof framing or slab checked for the added load
- A detail sheet and stamped calculations ready for plan check
