CORRECTION / AUESTION LIST: t. Email Kumar & Associates geotechnical report 2L-7-232 as noted by Mike on sheet S3.2. Send to cwirth@sarfield-countv.com. I sent it to Teresa an 81L7123. Mike Arbaney was good to forward a copy, thank you. Teresa is out today, she may have scanning documents pending at her desk or it may still be in her email system. No worries. z. l'm concerned there may be an errata or room label discrepancy on some of architectural sheets and ask for further clarification on some upper floor and attic area details. 3.a Sheet 44.3 Building Section 2 shows an "office", is that correct? (Wondering if that's an errata as an office room has not reflected in the received structuralframing pages nor on the electrical plan details). l'm not sure I totally understand, the arch plan and section 2/A4.3 have the same labels with the exception of "bunk room" vs. "bedrootì1". The Office is on sheet A2.L east of the Entry and called out as such on the arch plans and sections. l'm clear on the office on 42.1 entry level floor plan (located in general proximity of main level below the deck hot tub). The "office" I questioned - -is that "label" or note on Building Section 44.3 on the upper story above the powder room and kitchen??? Let me know. 3.b.Sheet 42.2 Upper Level plan depicts a hot tub deck and bunk room, is that still correct? Please confirm if any room labels have changed. These are accurate. Good, thank you. 3.c. Are any spaces on the second story proposed as "unfinished" future living space? No. 3. We are requesting further information on the proposed unconditioned "attic spaces". 4.a. where are attic access opening(s) proposed to be installed? TBD, I usually go over those with the owner during framing so they can be involved and visualize it easier. 4.b. will any of the attic areas be used to house, store or access mechanical equipment, such as L-2 ERV or whole-house ventilation equipment? lf so, please expound. The house will have (2) ERV units, likely located in the attic spaces so the access panels will be large enough to remove/replace the equipment. 4.c. will 220v. evaporative coolers shown on roof plan be "roof mounted" or contained within the "non-vented attic space" Sorry still not clear on this item, should I look at your response in red under 4.d?? 4.d. are any of the attic areas anticipated as "unfinished" future living space? That is a placeholder but llkely not used, the owner ls shlftlng towards a mini-split system to cool the house. Would like more detail, concerned where in the structure attic areas may be anticipated as"unfinished" future living space. (lf there is to be unfinished future (potential) living space, that may create aconcern with having to fire-sprinkler the 2 4. Colleen W¡rth Building Plans Examiner Garfield County Community Development 1OB 8th Street, Suite 401 (970) 94s-1377 exLL6TO cwi rth @ea rfield-cou nty,cpm building to meet Carbondale & Rural Fire Protection District provisions for fire areas in excess of 6,200 sq ft.; fire-suppression system will be easier to install during original construction then to retrofit the building later, if applicable). Perhaps your response in red above is meant to match response in 3.c.? 4.e. will attic access opening(s) be sealed and gasketed pursuant to 20L8 IECC to separate from rest of heated, conditioned living space(s)? The insulation is on the underside of the roof sheathing throughout the house so the "conditioned" part of the attic spaces refers to location of the insulation only. The access panels would be on the warm side of the insulation envelope. Okay, thanks for confirming the intent. ln evaluatingthe plans for compliance with the adopted 2018 IECC (lnternational Energy Conservation Code), there appears to be some missing bits. 4.a. Please have Architect of Record prepare and email a written statement expressing which chosen Energy Compliance Path has been selected for the Nickolay residence on Lot 29 in Coryell Ranch. Staff comment and feedback: lnasmuch as noting lJ-foctors ond R-values on plans submitted with no occompanying RESCheck, RESNET ond HERS RATER doto, moy, indirectly imply one is not pursuing a uA-olterative nor a Performance Method or ERI lndex opproach - we need to know the Architect of Record hos specificolly designed under the PRESCRIPTIVE poth and for us to use PRESCRTPTTVE residentiol energy value tobles in the 20L8 IECC without ony proposed trodeoffs ond without reference to the UA-tables. lf, however, you aim to pursue q performance path, we need to know which energy poth and whot further documents will be remitted for the fite record and stapted to the issued FTELD COPY for use during constuction. ff il will work, I would like to use the prescriptive path. Are there details or decisions still remaining that would cause your design somehow to be constructed under different energy compliance path? lf not, then: "Bruce Barth, Architect of Record, has designed the Nickolay residence at Coryell Ranch, Lot 29, 140 Spirit Mountain using the 'PRESCRIPTIVE PATH" of the 2018 lnternational Energy Conservation Code (IECC)." The intent is know the chosen energy compliance path before the plans examination is performed and prior to building permit issuance. 4.b. Provide ManualJ Report. Can I submit this once the plumber has it completed by the supplier? The Manual J Report is due during original plans examination of the 2018 IECC and prior to building permit issuance. Manual J Report is required now, not a deferred submittal document. 4.c. Provide type and method of the home's proposed Whole-House Ventilation system (exhaust only, supply only, combination supply and exhaust venting system). The house will have (2) ERV units exact location TBD. Do you know the general location for placement of the (2) ERV's and how they will be accessed for service and maintenance? THANKS FOR YOUR TIME AND CARE ON THIS PROJECT, I LOOK FORWARD TO HEARING A RESPONSE AND SEEING THE NICKOLAY PROJECT MOVE FORWARD.
