Fort Collins Equipment Pads

A couple of yards of concrete, sometimes less. Placing it takes about as long as it takes to describe. Everything that decides whether the machine sits dead level, whether the conduit comes up where your electrician wants it, and whether the anchor bolts line up with the holes in a steel base, happens in the three hours wrapped around those twenty minutes.

We pour pads across Fort Collins for condensers and heat pumps, standby generators, transformers, propane tanks, and light commercial equipment, from side yards in older neighborhoods off Old Town to new mechanical yards out along Harmony. Small pour, zero slack. And in a town that spends a serious portion of the year below freezing, the pad under the machine you care about most in January earns the same morning as anything bigger.

The hours before anybody calls the plant

Layout comes first and it comes off paper, not off a guess. The equipment submittal gives us the footprint, the anchor pattern, the clearances the manufacturer wants around it, and where the conduit or the gas line enters. We string that on the ground and then argue with it: can a technician actually stand there, does the service door still swing, is the pad clear of the drip line off the roof, and does snow slide onto that spot every February.

Then the ground work. We dig past the topsoil and anything soft, bring the hole back up with base rock in shallow lifts, and compact each one. That step is where a pad tilts or holds. Forms get set square and checked with a laser, the isolation joint goes in against any structure the pad touches, steel gets tied on chairs, and the electrician's stub-ups get braced so they stand exactly where they belong when concrete pushes against them.

What has to happen while the concrete is still plastic

The morning, in the order it actually runs

• Submittal reviewed and the footprint strung on the ground with clearances marked
• Utilities located, then hand digging anywhere near a gas or electrical run
• Excavation to depth, with soft material removed rather than compacted over
• Base rock in shallow lifts, each one run with a plate compactor
• Forms set, squared, and checked level in both directions
• Conduit stubs and sleeves braced to their exact locations
• Steel tied on chairs, isolation material against any adjacent structure
• Concrete placed, screeded, textured, edged, and covered to cure

Cold mornings, hot afternoons, and small pours

Small placements lose heat fast, which makes them fussier in the cold than a big slab. There isn't much mass in a couple of yards, so the concrete doesn't generate the warmth that carries a larger pour through a cold night. We use heated batch water and a non-chloride accelerator, we don't place on frozen ground, and we blanket the pad and leave it covered longer than people expect. Done that way, a January pad is entirely normal work here.

Summer flips the problem. A small pour on a hot, windy afternoon can stiffen before there's time to finish it properly, so we schedule pads early in the day from June through August. Whichever season it goes in, keep the first winter clean: shovel snow off it instead of chipping ice, and keep deicing chemicals away from concrete that hasn't had a year to mature. Sand for grip does the job with no downside.
