05/13/2020 PIMA COUNTY BUILDING-COMMERCIAL REVIEW Reqs Change T20CM00682 – PLAN REVIEW COMMENTS
BUILDING – COMMERCIAL - Reviewer: Chris Anderson
1. Please respond to all review comments in writing.
2. The Levels 2 and 3 Code Conformance plans on sheet A0.20 show balconies on the west side of the building extending across the property line into the public right-of-way. Please submit proof that the proposed aerial easement shown on the Development submittal sheet 6 has been approved by the City of Tucson. A building permit will not be issued before approval of the proposed easement.
3. PER PREVIOUS UNANSWERED REVIEW COMMENT FOR T19CM07181: “Aerial photographs show that the west façade of the existing building to the east has numerous 2nd floor windows and door and window openings on the ground floor. Since the proposed new building is to be located about a foot from this property line please address the following concerns per Clayton Trevillyan, Chief Building Official:
a. Submit a survey of the existing building location as it appears to cross the existing property line.
b. The blocking of natural light, ventilation, and possible emergency egress and rescue openings for the existing apartments in the Lewis Hotel.”
4. PER PREVIOUS UNANSWERED REVIEW COMMENT FOR T19CM07181: “There also appears to be ground mounted mechanical equipment and vertical surface mounted ductwork that the new building might impede. Please include this equipment on the Level 1 code conformance plan, sheet A0.10, to show that it is not impeded. Ref. 2018 107.2.1.”
5. Also, it appears from an aerial photo that existing ground mounted equipment and ductwork (see building review comment 3 above) are located in front of the stair bottom and may impede exiting from this proposed stair. Ref. 2018 107.2.1
6. A note on the development plan, sheet 5, calls for “existing utility infrastructure to remain.” This equipment is shown located above and in front of the proposed new landing and stair for the existing building exit. What is this utility equipment and will it impede width of the exit. Also are required clearances and locations for these utilities per Codes with the new landing and stair located in front of them? Provide an accurate, enlarged, dimensioned drawing of this egress area showing all existing equipment and relationship to new structure. Also be aware of the ICC/ANSI A117.1-2009, 4” encroachment limitation into required egress. See also building review comments 3 and 5 above. Ref. 2018 107.2.1
7. Per 2018 IBC 1027.3 the required south exit stair can be an exterior stair, however it shall be open on not less than one side except for required structural columns, beams, handrails and guards. The Code Section requires that the open side shall be shall have not less than 35 square feet of aggregate open area adjacent to each floor level and the level of each intermediate landing and located no less than 42” above landing and floor levels. The intent is to eliminate the buildup of smoke and gases at the landings and floor levels. The enlarged section and plans on sheet A3.10 show that this stair is fully enclosed, albeit with perforated metal panels. Full enclosure by perforated screens and solid wall does not comply with the intent of the Code per the Chief Building Official. While perforated screens are allowed as part of the “aggregate” open area, unscreened, open areas located no less than 42” above all landings and floor levels shall also be provided.
8. Please change keynote 4 for “Keynotes – Level 2” and “Keynotes – Level 3” on sheet A0.20 to “openings not allowed” and reference Table 705.8. 705.8.6 does not apply here.
9. Specification Section 07 21 00 2.1 indicates 6 ½” thick insulation shall have an R-value of 19 and 3 ½” insulation shall have an R-value of 11. The EIFS Section 07 24 13 does not specify insulation thermal properties at all, and neither does the roofing Section 07 54 23. Either show compliance with the prescriptive insulation values of 2018 IECC Table C402.1.2, using the R-values in the “Group R” column for the residential upper floors and the R-values in the “All other” column for the commercial ground floor or submit a COMcheck for the thermal envelope if proposed R-values are different to show compliance. Either way, clearly indicate on building/wall sections and in the Specifications required insulation R-values for the roof and all exterior walls. The Climate Zone is 2.
10. No information is given in the architectural drawings nor Specification Sections 08 41 13 and 08 41 23 regarding energy performance of the exterior envelope fenestration (doors, storefronts and windows). Either show compliance with the prescriptive U-factors and SHGC values of 2018 IECC Table C402.1.3 or submit a building envelope COMcheck if proposed values are different. Either way, clearly indicate on building/wall sections and in the Specifications U-factors and solar heat gain coefficients (SHGC) required by either the IECC Table or by the COMcheck. The Climate Zone is 2. If a COMcheck is submitted, all assemblies used shall match the architectural drawings and specifications. Ref. 2018 IBC 107.2.1.
11. General Note 2 on Wall Sections sheets A5.10 and A5.11 refers the plans reviewer and contractor to Code Plans and Code Building Section and says to “provide fire treated/resistive materials as required for UL designation.” While the notation in these locations do indicate basic materials and components for the fire-tested assemblies noted, specific product manufacturer’s and fasteners required by the listings are not identified in the documents. Either include all the information required by the listed assemblies shown in the notes or include printouts of the tested assemblies in these documents. If a COMcheck is submitted, all assemblies used shall match the architectural drawings and specifications. Ref. 2018 IBC 107.2.1.
12. GSN Foundations note 1 references the basis of design as PE soils report #19-050 and addenda. Please submit copies of this report and addenda for checking the foundation design documents. Ref. 2018 IBC 107.2.1.
13. Please verify footings C.0, D.0, E.0/1.3 and D.7/4.1. Foundation plan shows F7 with (6) #5 E.W. while calculations, page 266, requires (7) #5 E.W. Ref. 2018 107.2.1
14. Please verify braced frame #1 footings A.1 and A.6/1.0. Foundation plan shows F10 with (13) #6 E.W. while calculations, page 284, requires (17) #5 E.W. Ref. 2018 107.2.1
15. Please verify braced frame #2 footings F.0 /2.8 and 3.8. Foundation plan shows F10 with (13) #6 E.W. while calculations, page 300, requires (18) #5 E.W. Ref. 2018 107.2.1
16. Please verify main frame footing A.2 /6.0. Foundation plan shows F7 with (6) #5 E.W. while calculations, page 280, requires (7) #5 E.W. Ref. 2018 107.2.1
17. On the foundation plan, sheet S2.0, detail callout 213 is shown at the corridor wall location close to column line 6.0. This is the sump pump detail. Revise this callout and show sump in elevator pit. Ref. 2018 107.2.1
18. Details 208 and 211, sheet S4.0, show dashed lines for concrete slab at top of foundation. This configuration probably will not achieve the EIFS weep screed clearance to paved surface required by the EIFS manufacturer. It is likely that the foundation will need to be extended a few inches above paving surface to achieve. See drainage plan, sheet 4 of the Development Plan as it appears that paving is at the same elevation as the floor slab at the southeast corner of the building adjacent to the new stair landing and along the south wall. And please confirm this detail with proposed EIFS manufacturer’s standard base detail. An architectural detail is needed for these locations. Ref. 2018 107.2.1
19. Detail callout 209 is shown on the foundation plan, sheet S2.0 in two places for the masonry east wall. Should this callout be 210? Ref. 2018 107.2.1
20. On the foundation plan, sheet S2.0, detail callout 210 is located on the east side of the south wall. Is this correct? There does not appear to be an existing building in this location. Ref. 2018 107.2.1
21. On the foundation plan, sheet S2.0, detail callout 214 located at the column on the upper right corner of the plan does not seem to correspond to the condition. Ref. 2018 107.2.1

1. Please respond to all review comments in writing.
2. The Grading Plan in the Development package, sheet 4, indicates the new stair for the existing building exit door at the southeast corner. According to notation the well is existing building floor is 18” – 19” below grade, therefore this is a stairwell. What provisions are made to get rainwater out of the well and prevent flooding of the existing building during monsoons? Ref. IPC 106.3.1.
