COMMENTS:

1. Keynote 2 on the mechanical sheets appears to be pointing to the kitchen hood duct instead of the dryer vent. Please revise. Reference: Section 107.2.1, IBC 2024.
2. Booster fans are prohibited. Domestic booster fans shall not be installed in dryer exhaust systems. The specified dryer booster fan is not listed to UL 705. Reference: Section 504.6, IMC 2024.
3. In Detail 108, the dryer vent is shown discharging toward the outdoor air intake. In addition, the plans show the OA intake coming from the side of the building, while Detail 108 shows the OA intake through the roof curb. Also, Detail 108 is not referenced on the floor plans. Please revise or clarify. Reference: Section 107.2.1, IBC 2024.

Site Engineering Review Comments:
1. Site Engineering has completed its review of the submitted building plan set and cross-referenced it against the associated Development Package. However, final approval of Commercial TC-COM-0626-00859 cannot be granted until the associated revision to Development Package TD-DEV-0626-00859 has received full approval and been issued. Per UDC §3.3.3.G, building permits for sites requiring a Development Package may not be issued prior to DP approval, as the building plans must be consistent with an approved site plan. Please resubmit for final approval once the Development Package has been approved and issued by all applicable reviewers. For final approval, ensure the building plans match the approved DP with regard to footprint, proposed height, and square footage, and that the downspout and structure drainage systems shown in the building plans are consistent with those depicted in the Development Package plan set.
