BCAB #1739 - Fire-Resistance Ratings for Floors and Roofs, Article 22.214.171.124.
January 16, 2014
Re: Fire-Resistance Ratings for Floors and Roofs, Article 126.96.36.199.
The project is an 800 square foot building with a basement. The building serves as an office for an RV park and the basement contains water and electrical services for the RV sites as well as for the building itself.
Reason for Appeal
Article 188.8.131.52. requires a fire resistance ratings between floors.
The appellant contends that the basement is a service room as defined by the code. Due to its size and the limited quantity of equipment, it is exempt from the requirements for fire separations as per Sentence 184.108.40.206.(2) and Clause 220.127.116.11.(2)(b), respectively. The appellant further considers that because the basement is a service room, the requirements of Article 18.104.22.168. do not apply.
Building Official's Position
The building official maintains that the requirements of Article 22.214.171.124. apply and a 45 minute fire resistance rating is required for the floor. The exemptions to this required fire separation are not applicable. The requirements for service rooms are separate from the requirements for fire separations between floors and thus are not relevant to this appeal.
Appeal Board Decision #1739
It is the determination of the Board that Article 126.96.36.199. does apply and a 45 minute fire resistance rating is required for the floor assembly over the basement. The fire separation exemptions in Subsection 9.10.10. for some service rooms do not override the requirements for the fire resistance rating of a floor assembly.
