Exalanations:
According to the 2016 California Fire Code Section 304, 304.3.3 and 304.3.4, Exceptions 2:"
Storage in a structure shall not be prohibited where the structure is of Type I or IIA
construction, located not less than 10 feet from other buildings and used exclusively for
dumpster or container storage." The Alternate Materials and Methods Justifications for the
close proximity of the buildings is that the Exterior Wall of the Trash Enclosures will be fully
enclosed with no openings per Table 705.8, and no parapet is constructed so the first 10-feet of
the roof will be 1-hour fire rated per section 706.1.1, and the entire roof doesn't have to be fire
rated.
The attached sheets A-2 and S-2 shows that firewalls will be provided within 10 feet distance
from the neighboring buildings according to 2016 CBC Section 706 and 706.1. The trash
enclosure is a structure detached from the main building allowing collapse from either side, and
it is consistent to the CBC 706.2. According to the 2016 California Building Code, Table 601, for
the roof construction of TYPE II A construction, there is a note c says that: "In all occupancies,
heavy timber shall be allowed where a 1-hour or less fire -resistance rating is required." For the
proposed roof construction, the fire protection of the 1st 10-feet of ceiling is designed
according to AER-09038/ UL Design K504 (see detail 1/S3), which is a listed and approved
assembly. The system has no void and/or gaps, and, therefore, is equivalent to the intent of
"heavy timber" in the aspect of fire rating.
