Just before the Covid-19 pandemic shut down the country, we completed the mitigation of a 4-story, 200 unit, senior living facility in Phoenix Arizona.

There were quite a few challenges. We had to get over 2000 linear feet of 4″ piping from Dallas to Phoenix. We got it ordered and had it shipped, but it was shipped without a piggyback forklift on the truck. We had no forklift, so with our ingenuity, we built a ramp on the side of the truck and literally let them roll off. It was a little nerve-racking, but it actually worked great. Saved us at least 2 hours of pointless unloading by hand.

Our next issue was getting the concrete x-rayed (GPR). The pans showed 6-8″ slab thickness where we were originally wanting to core, but our GPR was showing it to be over 2 feet. If we wasted our time and effort trying to core through 2 feet of concrete, we wouldn’t have even been able to get anywhere with bringing our radon levels down. We ended up moving them into the, not as optimal, laundry rooms. We were able to get areas around 8-10″, so that was doable. And we would get the results we needed.

One of the many trouble spots we had to patch up while trying to get through each floor.

Then comes the fun of getting through each floor! Luckily, most of the action was between the first and second floors, so after a few adjustments, we were getting everything run. But there were large platforms on the roof holding the AC Condensors, so we were scared we would have trouble going from the fourth floor to the roof. It worked out though because there was enough space between the fourth floor and the roof that we were able to turn the pipes and get them exactly where we wanted them to come out on the roof.

From there we installed the fans and wired them up. Once the system is running, it only takes about 24 hours to lower the radon levels. Unfortunately, we haven’t been able to get back out there to do our follow-up testing because of the coronavirus and shelter-in-place. We are hoping to get those results done at the beginning of the May.
