The above drawings for the radiant floor for the first and second floor are well done except one critical component was not accounted for. Which direction will the flooring be placed? This is important because the light weight concrete flooring system requires sleepers which need to be run in the opposite direction of the flooring so the flooring can be nailed to the sleepers. The wood ceiling in the buildings 2nd floor under the roof and the 1st floor bedroom really dictated that the flooring be run in the same direction which is length wide with the building. This was one of those O'$%#@ that was realized onsite a few days before the radiant floor tubing and sleepers were going to be installed.
Now granted we could have called the Engineers and had it redesigned but schedules were already committed to and our HVAC contractor had a comfort level that he could use the concepts above just kind of reverse it. Hopefully we will be able to produce an "As Built" plan so what is in cement is similar to what is in our drawings.
