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.
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.
In alignment with our LEAN values, MacDonald-Miller has invested heavily in our plumbing prefabrication capabilities enabling us to install a higher quality system in less time for your building. Our plumbing fabrication shop specializes in everything from multi-trade racks (MTR’s) to prefabricated risers to entire bathroom wall assemblies, and, we’re continually finding innovative ways to realize the benefits of off-site fabrication.
Product Delivery Ingenuity
We’ve designed, constructed, and certified a 5th Wheel Style Flatbed Trailer System that can be picked up and held by a tower crane. It allows us to pick up our material directly from the street just minutes after our delivery trucks arrive onsite. This trailer then acts as a stationary outrigger allowing us to unload our materials to any open deck – eliminating the restrictions of a permanent outrigger. This innovative solution will completely redefine the high-rise construction material handling and productivity process.
We act as our own distributor, and that translates into immediate service for our customers. Our filter shop creates custom filters, so if a piece of equipment demands a certain size not usually in stock, we’ll simply make it and deliver it the same day. Our Bag-It and Tag-It program has proven invaluable for delivering filters to the service zones. This keeps the 200 MacMiller technicians focused on seamless service that ensures customers’ buildings have the clean filters they need when they need them.
Multi-Trade Prefabrication Innovation
When it comes to Multi-Trade Prefabrication, MacMiller is ahead of the curve. As experts in design, coordination, planning, scheduling and hosting the prefabrication of multi-trade racks in our fabrication shop, we’ve executed an array of complex projects. We’ve successfully partnered with General Contractors, Electrical Contractors, Controls Contractors, Insulation Contractors & Drywall Contractors on such projects. This high level of offsite prefabrication reduces project scheduling, onsite installation time, and improves workforce safety.
