SUBJECT: Responses to Building Department Comments #1 Received January 9, 2019
CC: Madigan+Co (General Contractor)
1) Page: A0.3z Net Leasable & Net Livable Calculations: Is the garage for use by the commercial or
residential spaces? Is it for use by more than one unit? If only for use by a single residential unit, no
accessibility requirements will apply. If for use by more than one unit of for commercial, you must
provide a van accessible space. 2015 IBC 1106.
Response: Garage is for the exclusive use of one residential unit – the residence on level two.
Therefore, no van accessibility required.
2) Page: A0.5z Fire Separation & Thermal Envelope Diagrams: Unless you can detail how the dwelling
separation fire partition membranes will extend to the underside of floor or roof sheathing above with no
structural penetrations, the 1-hour horizontal assembly will be required to extend across the entire
footprint from outside wall to outside wall. Coordinate with structural to ensure no penetrations occur.
2015 IBC 708.4
Response: Per 2015 IBC 708.4, Fire Partitions are required to extend from the top of the floor/ceiling
assembly to the underside of the floor or roof sheathing, slab or deck OR to the fire-resistance-rated
floor/ceiling or roof/ceiling assembly above. The Fire Partition walls are intended to extend from the floor
assembly to the underside of the floor/ceiling or roof/ceiling assembly (e.g. Horizontal Assembly per
2015 IBC 711.2) above.
While the diagrams on A0.5z indicate minimum required separations between R2 and other
occupancies, the reality is that typical floor/ceiling assemblies are either F2/A7.02 or F6/A7.02, which
are both 1-hour rated. This can best be seen on the building section drawings on sheets A5.1, A5.2, and
A5.3. Note that A0.5z has been updated with clarifications to indicate the 1-hour horizontal assemblies
being continuous from wall to wall.
3) Page: A0.5z Fire Separation & Thermal Envelope Diagrams: This portion of the exit enclosure does not
stack with the rest of the enclosure. Please thoroughly detail with section cuts going each way to show
how you will maintain continuity of the fire barrier. No structural penetrations are permitted; revise
structural as necessary. All supporting construction must also be fire rated. 2015 IBC 707.
04/26/2019
Page 2 of 8
Response: We have added the requested sections on sheet A6.22 (drawings 2 and 3). In addition,
structural documentation was revised to accommodate separate, continuous structural support for the
fire barriers and horizontal floor/ceiling assemblies. Revised structural plans include S2.0, S2.1, and
S2.2.
4) Page: A0.5z Fire Separation & Thermal Envelope Diagrams: The corridor serving as exit access for the
dwelling unit on the 2nd floor must have a minimum 1/2 hour fire rating. Walls must be constructed as fire
partitions (extend uninterrupted to the roof sheathing above or to the underside of an uninterrupted ½
hour rated horizontal assembly) and doors must be 20 minute rated. (2015 IBC 1020.1, 716.5)
Response: Diagrams on A0.5z has been updated to account for this. Door schedule on A8.2 updated to
reflect change to one door that was not called out as 20-minute (door 1/215). Plan indications of 20-
minute fire partitions were added to A2.2. Wall assembly detail W10 was edited to include a “Sim.”
Condition note where the resilient channel can be omitted from the wall while maintaining a minimum
20-minute fire resistance rating (UL assembly U305, which is 1 hour rated). A typical head and sill detail
at the interface between fire partitions and horizontal assemblies has been added as drawing 4/A7.04.
5) Page: A0.5z Fire Separation & Thermal Envelope Diagrams: You have numerous vents, piles, etc.
running through all stories at the location of the mechanical rooms. Demonstrate how you will protect the
penetrations/openings per 2015 IBC 712. If you use a shaft enclosure, detail the construction as a fire
barrier.
Response: The mechanical and plumbing chase is being protected using a shaft enclosure per IBC 713.
Walls and horizontal assemblies will be constructed as fire barriers with continuity per IBC 713.5. The
shaft enclosure will not be enclosed at the bottom for practical purposes and per IBC 713.11.3. See
sections and enlarged plans added on sheet A6.26 detailing the continuity of 1-hour rated fire barriers
through the shaft enclosure. Shaft wall assembly was added to A7.0C and A7.01.
6) Page: A0.5z Fire Separation & Thermal Envelope Diagrams: No Comment here.
Response: No formal comment was associated with this clouded note. No response needed.
7) Page: A0.5z Fire Separation & Thermal Envelope Diagrams: The interior exit stair must be separated
from the exit passageway by a 1-hour fire barrier and 60-minute fire rated door (2015 IBC 1023.1 and
716.5).
Response: A 60-minute door has been added (door 3/104) to separate the interior exit stair from the exit
passageway. Note that the door swings into the stair due to the low occupant load (less than 50) and to
avoid a door swing conflict with door 1/104. The concrete shaft assembly W15/A7.02 (Sim.) is already
designed as a minimum 1-hour fire barrier and is continuous from foundation to above the roof.
8) Page: A0.5z Fire Separation & Thermal Envelope Diagrams: Why is this portion of the exterior wall fire
rated? Property line separation distance may be measured to the center of the street. (2015 IBC 202).
Response: This was an error on the diagram and has been corrected on the updated sheet A0.5z.
9) Page: A0.5z Fire Separation & Thermal Envelope Diagrams: The walls, ceiling, and floor of the covered
area just outside the exit must be protected with the same level of protection as the exit enclosure until
the path of egress is open to the sky. Once open to the sky, the travel becomes exit discharge (egress
court in this case due to the narrow width against the property line) requiring 1-hour rating for 10’ up until
the alley. Please detail this and demonstrate in the fire ratings plan. 2015 IBC 1022, 1028.
Response: See sections 2/A6.22 and 3/A6.22 demonstrating the continuity of the 1-hour ratings at the
exit enclosure and exit discharge. The walls bordering the egress court are 1-hour rated (wall types
W14/A7.02 and W8F/A7.01) for greater than 10’ above the egress court floor (slab on grade).
10) Page: A0.5z Fire Separation & Thermal Envelope Diagrams: Trash containers of 1.5 cubic yards or
greater capacity require walls, openings, and overhangs within 5’ to be non-combustible (or comply with
one of the exceptions). Demonstrate compliances. 2015 IFC 304.3.3 and 304.3.4.
Response: Trash container sizes shall be limited to be less than 1.5 cubic yards to comply with 2015
IFC 304.3.3 and 2015 IFC 304.3.4. Any dumpster capacity of 1 cu yd (200 gallons) or greater shall be
constructed of non-combustible materials or of approved materials per IFC 304.3.4. Specific trash
containers shall be determined at later date by the owner along with their chosen waste collection
provider. Notes have been added to indicate these requirements on sheet A2.1. 04/26/2019
Page 3 of 8
11) Page: A0.6z Plumbing & Egress Diagrams: Your design complies but here’s how we’d typically
calculate: Commercial unit 1 has an occupant load of less than 15 and an exclusive single user toilet
room. This satisfies the toilet requirements for unit 1. (2015 IBC 2902.2). Commercial unit 7 has the
same situation. The total number of occupants minus the residential units and commercial units 1 and 7
is 34. 34/2 = 17 males, 17 females. Requirement is for 1 toilet and 1 lav for males, and one each for
females. Single user unisex toilet rooms may be used instead as you show.
Response: Thank you for the clarification. The calculation has been revised accordingly. Note that we
have provided accessible toilet rooms in these individual units per comments later in this document
(comments 18, 20).
12) Page: A0.6z Plumbing & Egress Diagrams: Add an egress diagram for the occupied roof deck. If the
roof deck is only for use by the free market residential unit, it may be considered an R2 occupancy. If it
is for use by more than one unit or by commercial, it will be considered an assembly occupancy and will
be required to be fully accessible. This includes the spas if commercial.
Response: We have updated A0.6z to include the requested egress diagram of the roof deck. This is
intended for exclusive use of the free market unit (R2 occupancy).
13) Page: A0.6z Plumbing & Egress Diagrams: The designated trash area of 105 sqft appears to encroach
on the minimum required egress width of 44” (2015 IBC 1028.4)
Response: The designated trash area of 105 SF is simply an area that is required to remain clear for
access to trash and recycling receptacles and therefore shall not impact the required 44” egress width.
See added note on A2.1.
14) Page: A0.6z Plumbing & Egress Diagrams: Include occupant loads for the mechanical rooms at 300 sqft
per person per 2015 IBC 1004. Include these occupants in your plumbing calcs as well.
Response: Sheet A0.6z has been updated per this requested.
15) Page: A1.2 Proposed Snowmelt & REMP Sheet: Provide documentation showing that the proposed
spas are either CEC or APSP-14 listed. Otherwise, it will be subject to RREMP. Ord. 40, 2016.
Response: The roof deck configuration has been adjusted for a different spa configuration. Please see
updated A1.2, A2.3. R-REMP calculation has been adjusted to indicate the revised specifications.
16) Page: A2.0 Proposed Basement Floor Plan: Detail the kitchenette in commercial unit 4 to demonstrate
compliance with accessibility requirements. 2015 IBC 1109.4.

28) Page: A5.2 Proposed Building Sections: Provide parapets at all exterior walls required to be rated due
to proximity to property line (or demonstrate how you meet one of the exceptions). 2015 IBC 705.11.
Response: Existing non-conforming condition (low existing parapet height on a portion of the existing
building beyond the setback line) should not be expanded per City of Aspen Zoning Dept. However, a
parapet conforming to the min. 30” height per IBC 705.11.1 is not required since the roof/ceiling
assembly (R2/A7.03) is 1-hour rated and is comprised of roofing materials which are not less than Class
B rated, which conforms to 2015 IBC 705.11 exception 4.
29) Page: A5.2 Proposed Building Sections: This wall is a dwelling separation wall. This makes it a fire
partition which must extend to the underside the roof sheathing without interruption by structure OR to
the underside of a 1 hour fire rated horizontal assembly ceiling. Also, please provide a callout for the
