The construction of the tent must still adhere to Section 3.2 Construction Materials, the square footage dictates whether the tent should require sprinkler protection. The approval process is fairly quick if section 3.0 is followed. I can come out and bless
it without delay.<br>

Hi Tim,<br>
<br>
I read the section on portable clean rooms, so just to confirm, if we <br>
keep the foot print below 65sf...we can build it with basic <br>
non-flammables (FR plastic, unistrut...ect)?<br>
<br>
or<br>
<br>
If the structure needs to be slightly larger than that...e.g. 84sf, how <br>
long is the approval process? Is it just a few days, or will it take <br>
more than that for the approval items:<br>
1. FPE inspection<br>
2. Protection requirements for the room.<br>
3. Assignment of the unique identifying number.<br>
4. Permit issue<br>
<br>
Thanks in advance, this information will help us plan efficiently.<br>
Marc<br>
