Big Foot Systems has supplied non-penetrative HD Beams as part of an HVAC replacement on the roof of the Mycon General Contractors headquarters in McKinney, Texas. The contractor on the project, ACIS Inc., used sixteen HD Beams to support two air cooled chillers on the Thermoplastic polyolefin (TPO) single-ply roof at the headquarters.



Big Foot’s HD Beams were specified by ACIS Inc. because the beams created a freestanding framework system that is non-penetrative. This was an important criterion due to the single-ply membrane roof, since avoiding roof penetrations helps mitigate the risk of potential leaks. Plus, the ability of the contractor ACIS Inc. to construct the Big Foot supports without needing to call in roofers was an additional benefit, saving cost and time on site. 

“The Big Foot Frames were easy to assemble and adapt to the roof. The ability to adjust the legs and keep the units level so we could accommodate the pitch of the roof was very useful” said Zak Keller, Project Manager at ACIS Inc. “The HD Beams were readily available and the price was competitive, both of which were great advantages. We received the shipment complete and on time – I’ll use Big Foot again with retro chiller applications.”

An HD Beam is a non-penetrative support frame for chillers, AHUs, packaged plant, generators, pipes and steels. It is a robust but adaptable solution where space may be limited, or there is a requirement to position it directly over existing structural roof beams so weight is evenly distributed across the specified quantity of HD Beams.

It is also height adjustable to maintain a level system on roof falls up to 5 degrees.
