Mr. Audie Wallace McKinstry Co., LLC Plan Check Number: X1907-001, Second Building Review August 29, 2019 Architectural 1. This comment has not been completely addressed. The original comment stated that Sheet M4.24 shows a ceiling diffuser penetrating the corridor ceiling at Grid 19/2.5, and that a smoke damper shall be provided. Sheet M4.24 was revised to provide a damper at Grid K/3.8. However, the damper only prevents smoke from infiltrating the rooms served by this branch of the duct and is not sufficient to prevent smoke from traveling through the remainder of the system. The design shall be revised to relocate the damper or provide additional dampers to prevent smoke from entering the system. The required rating for the dampers shall be specified per IBC Section 717.3.2.2. See IBC Sections 710.8 and 717.3.2.2. 2. This comment has not been completely addressed.

The drawing set appears to be revised per the Drawing Index on Sheet M0.01. In addition, the drawings listed in the Index do not match the sheets included in the set. The Index shall be revised. Note that Sheet M0.01 was only included in one of the two replacement sets resubmitted. Two complete sets shall be provided. See IBC Section 107.2.1. 6. The project includes numerous piping that penetrate the walls and wall membranes, and the horizontal assemblies. The architectural drawings under Permit No. B1904-036 do not include details for sealing the penetrations in the fire and smoke barriers. Details shall be included in the mechanical drawing set to seal the penetrations. The details shall include rated assemblies and shall provide the test listing. See IBC Section 714.
