Hello,
The installation contractors state that on previous LEED projects they have placed down plastic sheeting down in order to protect the raised technical floor. Correct me if I am wrong but for me this is not a "requirement" in the SMACNA chapter 3 guidebook. This could be requirement if the HVAC system was in the flooring, but this is not the case).
1) Can someone confirm whether of not this is a requirement?
2) Before sealing the floor & installing the carpet does the SMACNA require that cleaning be done underneath the raised floor or is this just a good-practice?
Regards,
Ian
