Show all requied snow stops. Subject: PlanCheck Page Label: A3.4 Author: justinh File Name: ARCHITECTURAL(24X36).813 W Smuggler.2019.08.pdf Color: Where roof drains are provided, secondary roof drainage must also be provided (IRC 903.4.1). This is required anywhere water would become entrapped if the primary drains failed for any reason. Additionally, IPC 1108.2 requires that secondary drainage discharges to a conspicuous location so that building occupants will become aware that the primary drains are failing. Identify where this secondary discharge location will be on the applicable elevation or floor plan. Show the electrical panel location on the floor plan as well as the utility meter location.

Subject: PlanCheck Page Label: A5.1 Author: justinh File Name: ARCHITECTURAL(24X36).813 W Smuggler.2019.08.pdf Color: I need a little more information to verify your class A roof coverings for RA1, 2 and 3. Please specify the specific types of folded seam roofing and single ply membranes you are proposing. I've attached ESR-2053 for versashield to this comment letter. If you want to use this as documentation of class A assembly you may, but you will need to specify the specific covering material proposed in order to comply with footnote 2 on table 1 (page 3). Your assemblies match what is described in table 1, but in order for me to be able to accept them you need to be using one of the specific products listed on table 2 on page 4, otherwise I will need a different ES report or UL listing specific to what you will use. Subject: PlanCheck Page Label: A8.3 Author: justinh File Name: ARCHITECTURAL(24X36).813 W Smuggler.2019.08.pdf Color: Detail the typical flat roof assembly and snowmelted roof deck assembly as you have the sloped roof assembly. Subject: PlanCheck Page Label: F.l Author: justinh File Name: ARCHITECTURAL(24X36).813 W Smuggler.2019.08.pdf Color: Gross floor area and fire area should be the same in this scenario, both are the areas enclosed by exterior walls (measured to the interior face of the exterior wall) or under the projection of the floor or roof above. It appears that your fire area is the correct measurement, please revise the gross floor area to match or just show the fire area, but they should not be shown as different values.

Subject: PlanCheck Page Label: 2 Author: justinh File Name: Plan Rvw Rpt. Response Ltr.813 W Smuggler.2019.08.pdf Color: Details on A8.3 do not match what you call out in the roof assembly schedule - for example on A5.1 you call out RA-1 and 42/A8.3 for the same portion of roof. RA-1 you note as being 2" R12 rigid insulation with 3" spray foam and R19 batt on the schedule, but you show 42/A8.3 as being 4" of rigid insulation and make no mention of spray foam or batt insulation. Revise you plans so that all roof assemblies, the corresponding details, and the ResCheck match. Plan Rvw Rpt. Response Ltr.813 W Smuggler.2019.08.pdf (3) Subject: PlanCheck Page Label: 2 Author: justinh File Name: Plan Rvw Rpt. Response Ltr.813 W Smuggler.2019.08.pdf Color: ResCheck shows R50 cavity but per the roof schedule you are calling out R12 continuous insulation with R38 cavity insulation. The total R value is the same but the types are different. Revise one or the other to match. Subject: PlanCheck Page Label: 2 Author: justinh File Name: Plan Rvw Rpt. Response Ltr.813 W Smuggler.2019.08.pdf Color: Multiple wood frame walls still show R19 as the cavity insulation on the ResCheck, revise all wood frame walls to reflect this change. Subject: PlanCheck Page Label: 1 Author: justinh File Name: REMP Form.813 W Smuggler.2019.03.pdf Color: Provide a REMP plan in the architectural set that shows the location of all snowmelted area. If any snowmelt extends into the ROW it must be on a separate zone, note this requirement if applicable. Provide a detail for the driveway snowmelt assembly that shows a minimum R10 insulation under the snowmelt.

The one submitted has no signatures. STRUCTURAL(24x36).813 W Smuggler.2019.08.pdf (1) S-1 Related to Structural plans, calculation pkg. & Structural thru Coordination with Geotechnical information provided: S-6 CCC Concern: various questions & requested corrections re: general notes, coordination with geotechnical information given proximity to the micropile wall, and 2-details. Our response: Please review revised Structural drawings (S0.1 through S3.2), and memo prepared by Albright & Associates addressing items S-1 through S-6, along with 2-letters from HP Kumar, which are attached to this letter. EN-1 Sheet M-5 (Mechanical List & Sequence of Controls) CCC Concern: Sequence of Control #5 domestic hot water circulation pump does not comply with Section R403.5.1.1 Our response: Our Mechanical Engineer, Burggraaf Associates, Inc., has revised Sequence of Control #5 to comply with R403.5.1.1. EN-2 REScheck & Sheets A5.1 & 2 (Building Sections) a. CCC Concern: While REScheck indicates an R-50 ceiling assembly above the Yoga, Sump, & Storage rooms (NW corner of building), the drawings do not provide detail for this assembly. Our response: Both building section drawings now have a notes and a Roof Assembly Schedule that provides detail for the various locations and roofing conditions on the building. EN-2 REScheck & Sheets A5.1 & 2 (Building Sections) b. CCC Concern: While REScheck indicates several R-50 roof/ceiling assemblies, manual J & the Roof Dew Point calc indicate a R-70 assembly, & the drawings have discrepancies between sections & details. Our response: See pertinent remarks directly above (EN-2.a) that clarify these discrepancies. Manual J & Roof Dew Point Calc’s have been corrected to reflect use of R-50 roof insulation assemblies. EN-2 REScheck & Sheets A5.1-2 + A8 series (Building Sections + Details) c. CCC Concern: While REScheck indicates R-3.6 continuous insulation on the above-grade walls, drawings show R-5 (5.1) ThermalStar One structural insulated sheathing. Our response: Our REScheck has been revised to reflect R-5 SIS panels as our continuous insulation method. EN-2 REScheck & Sheets A5.1 & 2 (Building Sections) d. CCC Concern: REScheck & drawings indicate use of R-19 batt insulation in 5 ½” walls, which does not fit uncompressed into a 5 ½” deep stud space (compressed to 5 ½”D, R-18 is the resultant value). Our response: REScheck & drawings have been revised to show use of R-21 high performance batts, which fit uncompressed into a 5 ½” depth. EN-2 REScheck & Sheets A6.1 & 2 (Window & Door Schedules) e. CCC Concern: While REScheck indicates a U-factor of 0.32 for all fenestrations (as does the Window & Door schedules), the window documentation sheet from Pella indicates lower (i.e. more thermally efficient, even below the prescriptive limit) values. Our response: The Window & Door schedules indicate a MAXIMUM U-value of 0.32 as justified by the REScheck, which is what we’ll provide. For the purpose of this response, we will alter the Pella window documentation to show a less thermally efficient product per REScheck, but will not have final documentation until this product has been ordered. In no case will the U-value be greater than 0.32.
