07/22/2020 DAN SANTA CRUZ ELECTRICAL-COMMERCIAL REVIEW Reqs Change Please address the following electrical plan review comments. Also provide a written response.
1. As requested per the precious electrical plan review. The lighting plan clearly shows 2 exhaust fans at different locations with their own designated branch circuit. Both fans are labeled #1. Please clarify. Also show the sequence of operation that correlates with the mechanical plans.
Ref; 2018 IBC sec, 107.2.1, 2017 NEC, 2018 IECC, City of Tucson Commercial Plan Submittal Requirements.
07/22/2020 ROBERT SHERRY MECHANICAL-COMMERCIAL REVIEW Reqs Change 1. The submitted ventilation calculation uses 3 occupancies: nail salon, entry lobby, and office. It also does not include the ventilation required for the floor area (0.12 CFM/Square Foot). Since you have only one air handler, you need to ventilate the suite as if it is one occupancy - a nail salon. [Initial comment: Complete the ventilation calculations. Air from the nail salon may not be recirculated to other occupancies. Reference: Section 403.2.1 (3), IMC 2018.]
2. With 17 nail stations, 850 CFM of local exhaust is required. [Initial comment: Provide 50 CFM of exhaust per nail station. Reference: Footnote h, Table 403.1.1, IMC 2018.]
3. The clouded note on the mechanical plan calls for a new exhaust fan to move 700 CFM while the same fan is shown on the duct diagram (B3/M0.1) as moving 400 CFM.
4. Provide adequate make-up air to the suite so that the suite pressure remains essentially neutral. Don't forget to include the continuous restroom exhaust when determining the outside air requirements. Reference: Section 501.4, IMC 2018.
07/22/2020 ROBERT SHERRY PLUMBING-COMMERCIAL REVIEW Reqs Change 1. Provide tempered water for the lavatory in the public restroom using a thermostatic mixing valve listed to ASSE 1070. Reference: Sections 416.5 and 607.1.2, IPC 2018. [Initial comment: Verify that the installation of the thermostatic mixing valve conforms to the manufacturer's installation instructions.]
2. Provide a metering faucet for the restroom lavatory, dispensing a maximum of 0.25 gallons per metering cycle. Verify that the faucet cycle will last for at least 10-seconds. Reference: Section 419.6, IPC 2018, as amended by the City of Tucson and Section 606.4, ICC/ANSI A117.1-09.
