Reviewer: Chris Anderson, November 6, 2019
BUILDING - COMMERCIAL
1. Please respond to all comments in writing.
2. On the first sheet identify the adopted building Codes that apply to this project. They are 2018 IBC, 2018 IPC, 2018 IMC, 2018 IECC, 2017 NEC, 2012 City of Tucson/Pima County Outdoor Lighting Code, ICC/ANSI A117.1-2009.
3. No information in this submittal is given regarding how this "clean room" will be used and what the function of the existing business/building that the new addition is attached to is. In addition no Code review is provided to shed light on the use for and possible hazard this proposed facility poses. Please clarify. Ref. 2018 IBC 107.2.1.
4. Submit a Code review showing occupancy and use classification per 2018 IBC Chapter 3 and occupant load per Section 1004. Clarify whether or not this addition will be fire sprinkled. Ref. 2018 IBC 107.2.1.
5. The Floor Plan, sheet 3, shows a prefabricated modular clean room to be provided by the Owner. Please provide manufacturer's layout and installation information for review to verify required electrical, plumbing and mechanical services and connection to proposed modular systems that will be installed in anticipation of the future clean room. Ref. 2018 IBC 107.2.1.
6. The Floor Plan, sheet 3, shows a 92-foot long service corridor with access at one end and termination at a solid wall on the other end. Please show that the length of the common path of travel for this space in in accordance with 2018 IBC Table 1006.2.1. Because exiting through a storage room is not allowed by Section 1016.2(5), you will need to draw a portion of the existing building to show a dimension for the full length of the common path from the blank wall at one end to a location at which travel to two separate exits is possible.
7. The laterally unsupported bearing wall height shown on cross section A-A, sheet 5, is 12'-0". Per 2018 IBC 2308.2.2 the prescriptive maximum stud height for bearing walls is 10-feet. Per 2308.1.1, where portions of the building exceed the limitations of Section 2308.2 those portions shall be designed in accordance with accepted engineering practice. Please submit structural calculations for the exterior walls sealed by an Arizona registrant. Calculations shall include static, lateral (wind) and seismic loading. Make all corrections to the plans, sections and details required by the engineering calculations.
8. Detail B/5 shows a new concrete foundation sitting on the existing building footing. Should the new foundation be mechanically tied to existing? Ref. 2018 IBC 107.2.1.
9. The roof construction shall have truss ties to the wall below to transfer wind uplift loads to the foundation in accordance with 2018 IBC Tables 2304.10.1 and 2308.7.5. Selected method(s) to be used and indicate on the cross section details, sheet 5.
10. Section & Detail Note 5 on sheet 5 specifies R-36 roof/ceiling insulation. However, 2018 IECC Table C402.1.3 requires the batt insulation shown to be R-38. Revise note.
11. Section & Detail Notes 6 and 8 on sheet 5 specify R-19 wall insulation. However, 2018 IECC Table C402.1.3 requires the batt insulation shown to be R-20. Revise notes.
12. Section & Detail Note 7 on sheet 5 specifies "adobe brick." Is this unstabilized adobe, stabilized adobe, or concrete slump block? Please clarify. 2018 IBC 107.2.1.
13. The section details on sheet 5 shall clearly show how the masonry veneer is to be attached to wood framing, how it will be flashed and weeped to direct moisture that has penetrated the system to the exterior. Ref. 2018 IBC 1404.4, 1404.6.
14. Provide structural calculations sealed by an Arizona registrant for the lintels supporting masonry veneer over the new exit door and 10'-0" wide temporary opening. Indicate lintels and lengths of bearing required at each side of opening on the east and south elevations, sheet 3. 2018 IBC 107.2.1.
15. Show depth of footings on footing details, sheet 5. Depth shall be minimum 12" below undisturbed ground. Ref. 2018 IBC 1809.4.
16. Include in the drawing set an outline specification showing minimum requirements for construction materials used in this building per 2018 IBC, including concrete, wood species and grade, insulation, adobe brick (see comment 11 above), roofing system, etc.
PLUMBING - COMMERCIAL
1. Provide a plumbing waste, water and vent plan for the hand wash sink and any other plumbing, if required in the modular clean room. Show all piping, valves, pipe slope, sizes of pipes and connections to existing systems. Ref. 2018 IPC 106.3.1.
2. Show mechanical unit condensate and auxiliary drain system piping with pipe size, slope, and proposed termination method per reference. On the drawings indicate traps in condensate lines as required by the heating and cooling equipment manufacturers. Ref. 2018 IPC Section 314 and City of Tucson Amendment to the 2018 IPC Section 314.2.1.
3. Provide vent penetration detail for roof. 2018 IBC 107.2.1.
4. Include in the drawing set an outline specification for plumbing materials and methods that comply with the 2018 IPC for waste, condensate, water, and vent systems.
MECHANICAL - COMMERCIAL
1. Provide heating and cooling load calculations performed for a summer db outdoor design temperature of 105-degrees F which is the ASHRAE design temperature for Tucson, AZ.
2. Provide a mechanical schedule on sheet 4 showing selected equipment and capacities at 105-degrees F summer design temperature. Per 2018 IECC C403.3.1 in selecting equipment, "the output capacity of the heating and cooling equipment shall not be greater than that of the smallest available equipment size that exceeds the calculated loads."
3. On the mechanical plan, sheet 4, show CFM's for all SA and RA grilles, and show all ducts and their sizes for each heating and cooling unit.
4. Show heating and cooling thermostats on the mechanical plan and specify controls in accordance with 2018 IECC C403.4.
