Martin,
Working with the consultants on this project, I have tried to address all of your comments from our initial
plan review submittal on June 27t", 2012. Below are my responses to each of your comments(a summary of
your comments are attached to this letter for your reference):
Page 1:
1. The civil engineer has created an erosion control plan and can be found on sheet C-3.
2. I had initially submitted a construction staging plan, but after speaking with Leonard Sandoval, I
have made a few modifications to it. Please see sheet A1.40.
3. I have created a new sheet illustrating the radon reduction system per the IRC. It can be found on
sheet A1.50.
Page 7:
1. The soils engineer and civil engineer have worked together to locate the foundation drains and
termination point. After several discussions with Dave Young at HP Geotech,we decided to go with
an infiltration pit instead of trying to daylight the foundation drains. The limited amount of slope on
the site would have made daylighting the drains challenging. This information can be found on sheet
C-2.
Page 8:
1. I have shown the proposed building sewer line(4"),water line(2"),electrical conduit(4"), and gas
line(3/4")on sheet A2.00.
2. I have indicated the two nearest manholes on Main Gore Drive North and their respective rim
elevations on sheet A2.00.
Page 12:
1. Working with the structural engineer, I have revised the roof plan (sheet A2.30)to show the locations
of a custom snow retention system. Details 8/A6.50 and 2/S4 show how this is to be built.
Page 13:
1. I have clearly indicated that a minimum height of 60" above grade be maintained at all intake and
exhaust vent locations per the Town of Vail code on sheet A3.00 and as a general note on all
elevation sheets.
Page 20:
1. At this location,the steel beam will receive solid wood blocking and a continuous layer of 1" rigid
insulation on the interior to create a thermal break. One could argue that the R-value is between 8
and 10, but it is probably closer to 5. In their ResCheck analysis,Architecture Engineering
Consultants(AEC)assumed all framing around the windows to have the same R-Value as the
windows themselves(R-4). See attached letter from AEC.
Page 23:
1. The structural engineer has provided additional details for the stairs on sheet S7, numbers 19, 20,
and 21, and called out all required special inspections in their general notes on sheet S1.
Page 25:
1. At this location, I have modified the detail to show the cripple stud space above the windows to be
filled with sprayed-in closed cell foam insulation with an approximate R-Value of 17.5 with additional
sprayed-in closed cell foam insulation being applied to the inside of the stud wall as well. However,
for the ResCheck analysis,AEC assumed this area to have the same R-Value as the windows(I
believe, R-5).
2. I have shown metal wall ties for the stone veneer in the wall assembly details that contain stone
veneer: 2/A6.10, 7/A6.10,9/A6.10,and 10/A6.10. Other details(like foundation details)may not
explicitly show the metal wall ties, but they will have a note referencing the above wall assembly
details.
Page 27:
1. At the cantilevered floor location, I have called out that there be 2" of sprayed-in closed cell foam
insulation (R-10)and approximately 10" of blown-in-blanket insulation (R-30),giving us an
approximate R-Value of R-40 at this location.
2. At the 2' "pop-out" in the kitchen, I have called out that there be 2" of sprayed-in closed cell foam
insulation (R-10)and approximately 5"of blown-in-blanket insulation (R-15),giving us an
approximate R-Value of R-25 at this location. I consider it to be more like a wall than a roof; it is
covered by the main roof above,so no snow will ever accumulate on it.
Page 28:
1. I have a provided a new detail showing how the sill is to be flashed:4/A6.40.
Page 29:
1. The structural engineer has created new details showing the metal guardrail attachment at the
Master Bedroom deck. They are 17/S7 and 18/S7.
Page 30:
1. The structural engineer has created a new detail showing the metal guardrail attachment at the
Living Room deck. It is 8/S7.
Page 31:
1. At this location,the steel beam will receive solid wood blocking and a continuous layer of 1" rigid
insulation on the interior to create a thermal break. One could argue that the R-value is between 8
and 10, but it is probably closer to 5. In their ResCheck analysis,Architecture Engineering
Consultants(AEC)assumed all framing around the windows to have the same R-Value as the
windows themselves(R-4). See attached letter from AEC.
Page 32:
1. I have added a column to the window and door schedules for U-Values. The U-Values for the windows
and glass doors have been provided to me by Sierra Pacific Window and Doors and Weiland Door
Company. We are planning on using these two suppliers, but should it change for some reason, I will
let you know. There are three other exterior doors that we have yet to select,so I don't know their U-
Values at this time. The custom entry door will most likely be a combination of insulated glass and
wood,the overhead garage door will be an insulated solid core wood door with cedar siding applied
to it,and the garage mad door will be a insulated solid core wood door(flush panel)with cedar siding
applied to it as well. We can provide this information when we get to this point in the process.
Page 33:
1. The floor drain for the mechanical room is show on the first level floor plan,sheet A2.10.
2. Carbon Monoxide detectors and Smoke Detectors are shown on the reflected ceiling plans,sheets
A9.10 and A9.20, per the IRC.
3. There is a general note on the reflected ceiling plans and lighting plans,sheets A9.10 and A9.20,for
all lighting to be at least 50%high efficacy.
Page 40:
1. Required special inspections have been added to the structural general notes on sheet S1.
Page 43:
1. Details for the snow retention system have been added on sheet S4.
Page 45:
1. We believe the set to be fairly well coordinated. In the few cases that it's not(which is to be
expected), it is the contractor's responsibility to immediately notify the Architect per the general
notes,so that we can provide the needed information.
Page 46:
1. The lateral design has been double-checked and additional notes for shear walls have been added to
the plans. Details 4, 5, and 6 on sheet S3 have been added to show additional steel connection
details for the lateral design. Additionally, detail 17/S6 shows metal strapping and the steel
connection detail at the Master Bedroom moment frame.
2. New details for the guard rail attachment at the Master Bedroom deck are on sheet S7, numbers 17
and 18. A new detail for the guard rail attachment at the Living Room deck is on sheet S7, number
8.
3. New details for the stair are on sheet S7, numbers 19, 20, and 21.

Ken,
We are issuing this letter to confirm how we performed the calculations in the REScheck
program. We understand that the proposed building have some wall areas made of
combination of glass and steel beams, some walls are assemblies with wood siding. For
those glass areas, we considered the entire wall as glass, adding steel beams into glass
assembly since these would have similar performance data. Therefore the beam areas
have same R-value as the glass assemblies (R-4) and not R-22 as is considered for
wood or stone wall assemblies. This R-value is slightly worse than expected R-5 value
for the beams, but we are still passing the code.
Hope this explains how we performed the Rescheck calculation. If you have any
questions, please give me a call.
Sincerely,
Martin Zourek
