Shop Capabilities
HVAC Fabrication
We specialize in high-level modular prefabrication of equipment skids and mechanical piping racks. And our timing is pretty special as well – we’ve constructed entire mechanical rooms in our fabrication facility and then raised these modules in place onsite in as quickly as one day. Our response to every mechanical piping request is “yes we can do that” – because, well, we can.
Pipe Fitting Prefabrication
Our in-house piping shop is adept with several types of fabrication including welded pipe of virtually any size, fabricating multi-trade racks, frames for equipment, custom supports, stainless steel and more. To maximize our efficiency and quality, our 3D BIM/Detailing teams send “spool” packets of our complex piping systems which are then broken into modular sections that are built in our shop and sent to the site for a seamless installation.
Industrial Fabrication
With a level of expertise that qualifies our shop as a regional leader in highly technical metal fabrication, we efficiently assemble and deliver commercial and marine ductwork and fittings. This capability is in thanks to our outstanding sheet metal workers, many of whom are veteran fabricators with a wide range of experience.
