QUESTION: |
1. Does “requires a chassis” mean that the chassis is a part
of the building structure? 2. Can an existing 4970 square foot portable classroom building (made of 5 modular sections) have a 3712 square foot addition (made of 4 modular sections) with a 2-hour fire-resistance-rated fire wall between the existing and the addition be approved without the requirement for an automatic fire sprinkler system? |
|
ANSWER: |
1. No. Section 902 defines a portable classroom as a structure designed to use a chassis for transport. The structure can be hoisted onto a flatbed trailer for relocation and still meet the definition of portable.2. No.
Washington State Amendment 903.2.2 requires an automatic sprinkler
system in all Group E occupancies except for portable classrooms or clusters
of less than 5000 square feet and Group E occupancies with an occupant load
of 50 or less. A two hour fire-resistance-rated fire wall would not
meet Section 705.4 of the IBC for separations. |
