Dear Asher Architects,
The County Building Department has performed the review on the building permit application
and plans for the new building proposed at the above address.
There are items that need to be addressed prior to considering issuance of the building permit
and items that can be addressed after the issuance of the building permit.
Please provide a response letter addressing each item listed in the "ltems to address prior to
issuing a building permit". Response not required for the "Conditions to be addressed during
construction" but please address if clarification is needed.
Please provide 2 complete sets of corrected sheets, with clouded areas reflecting changes, for
the resubmittal.

Corrections to address prior to issuins a buildins permit:
1 The insulation details delineated on the plans do not appear to match the U-Values
indicated in the COMcheck report submitted or the R-Values on the Cover Sheet 0.0. The
"lnsulation Requirements" on sheet 0.0 indicates "Actual R-Value to match COMcheck
report. The COMcheck Report was not produced using R-Values.
lf using the U-value method, please submit the calculations and u-values for each
component in each assembly. See the attached Commentary for that section of the
Energy Code for reference. Please provide cross sections of the wall assembly and
roof assembly detailing exactly how it is constructed.
lf using the R-Value method. Please provide cross sections of the wall assembly
and roof assembly detailing exactly how it is constructed. The roof will require R-5
thermal blocks if using the R-Value method.
2 S0.01 - The Design Criteria is indicating a 35psf roof snow load. The minimum design
criteria in Garfield County is 40psf. Please address accordingly.
3 The foundation design does not appear to follow the recommendations in the Soil Report
that was submitted with the permit. The report recommends helical piers but gives
recommendations for Shallow Foundations in 8.2.¡ Please have the structural engineer reference the specific soils report on the
drawings.. The Geotech Report recommends 400psf and 300psf for gravity loads and lateral
loads respectively. The Structural notes indicate 1500psf and 2000psf respectivelyo The Geotech Report indicates separating the slab from the foundations, columns,
etc. The details on the plans do not indicate separation.. There are no footings indicated for the interior bearing walls.
4 When more than one exit is required from a building at least (2) accessible means of egress
are required. The main entrance qualifies as one. Please provide an additional accessible
means of egress from the building. (lBC 1009)
5 The exterior exit doors are to have access to a public way or to a "Safe Dispersal Area" that
is 50'minimum from the building. Please indicate on the site plan how compliance is
obtained. (lBC 1028.5)
6 There is always a question regarding hazardous material storage in this type of facility.
Typically, in storage facilities the leases will cover hazardous material storage. Would you
please provide a statement or a sample lease agreement for the County's file. (lBC 414)
7 After speaking with the Fire Marshal, a Knox Box is to be installed at the entrance gate prior
to issuance of the building permits.
I Please indicate on the plans the termination location for the condensate lines from the fan
coil units.
I The emergency lighting is to illuminate the isles/corridors to one foot candle. The location of
the emergency lighting is at the exterior exit doors. The emergency light fixture specified will
illuminate to 24'. Please add interior emergency light fixtures to cover all the interior
hallways. (lBC 1008.3)

Conditions to be addressed durinq construction:
The approved plans are to be on-site for inspections.
Sanitary facilities are required to be provided for workers.
A list of required inspections will be attached to the plans. The State is to permit and
approve the electrical work.
https://www.colorado.oov/pacific/dora/DPO Electrical Plumbino Permits
Underground utility locates is the responsibility of the owner or contractor. 811 is the
Colorado Utility Locate Hot Line.
Drainage across property lines shall not exceed that which existed prior to grading. Excess
or conCentrated drainage shall be contained on site or directed to an approved drainage
facility. Erosion of the ground in the area of discharge shall be prevented by installation of
non-erosive down drains or other devices.
All backflow preventers are required to be tested and certified by a licensed backflow
specialist after installation and prior to issuance of the Certificate of Occupancy.
Separate Sign Permits are required for any external signs. Please contact the County
Planner for the apPlication.
Electrical Code compliance will be determined based on field inspections performed by the
State Electrical lnspector, (303) 869-3458. Please have the inspector sign the building card
or provide written documentation of the inspections.
The Electrical Code requires a separate Electrical Permit for low voltage fire alarms that has
an alarm panel and send a notification to the Fire District when under alarm. A Rough-ln
inspection with the State Electrical lnspector is required (303) 869-3458. Please have the
inspector sign the building card or provide written documentation of the inspection.
The fire sprinkler and alarm are required to be inspected and approved by the Local Fire
Protection District. Please provide shop drawings to the Fire District for review and schedule
the inspections accordingly. Please have the Fire Marshal sign the inspection card when the
rough inspection is approved and when the final inspection is approved.
Any water supply that feeds a fire suppression system is to be inspected by the Fire Marshal
for that Fire District prior to backfilling.
Please provide special inspections reports to the Building Department as specified within the
General Notes of the structural drawings.
Geotechnical observation is required when the excavation is complete and written
verification be supplied at footing inspection, 300psf/400psf.
Combustible material is limited in Type I and Type ll Construction. See IBC 603 for allowed
combustible materials.
Safety glazing is not designated on the plans. Safety glazing will be checked during the
framing and final inspection. (lBC 2406.4)

Any membrane and through penetrations of the fire resistive construction will be required to
be fire-stopped with listed fire stopping assemblies. The contractor is to provide a cut sheet
for the assemblies at the framing inspection. (lBC 713)
lf the fire sprinkler system requires a fire pump. Then the Utility Room that houses the pump
will be required to be one-hour construction. (lBC Table 508.2.5)
All accessible door hardware shall have a shape that is easy to grip, including pocket and
sliding doors. (ANSI A117.1 - 404.2.6)
The 2018 IECC requires a Blower Door Test to verify air sealing. There has been a struggle
to comply when garage doors are involved. The County is willing to waive the air sealing
requirements for the spaces that incorporate garage doors. The interior heated space within
this building can be sealed and tested. This will be a requirement prior to approving the final
inspection.
Please be aware of the door maneuvering clearance to the restroom. The bollards outside
the restroom should be 48" from the restroom door.
Lavatory temperatures are not to exceed 1 10 degrees

râble values refer to the U-values for the entire
Ãsembly, including air films and finish materials'
ì-ãwer U-values are better in that they indicate
leOuceO heat flow, while higher R-values are better in
iñat they indicate reduced resrsfance to heat flow.
ðimiturly, lower C-factors and F-factors indicate
ieOuce,i heat flow through basement walls and the
edoes of slabs on grade, respectively'-
öommentary Figure C402.1.4 provides an example
of the U-factor method. Shown in the figure are the R-
values for the cavity and framing. The U-factor is 1/R-
value. To calculate the U-factor for the combination of
the cavity and framing combined, calculate the U-factor
of the aôsembly based on the framing composing 15
oercent of the assembly. An assembly with a U-factor
äoual to or less than that calculated in Table C4Q2.1.4 is
oermitted in this method. The estimated framing is 15
þercent of the wall area. The U-value may be calculated
as follows:

C402,1.2 Equipment buildings. Buildings that comply with
the following itratl be exempt from the builcling thermal
envelope provisions ofthis code:
1. Are separate buildings with floor area not more than
500 square feet (50 m2).
2. Are intended to house electronic equipment with
installed equipment power totaling not less than 7 watts
per square foòt (75 Wm'?) and not intended for human
occupancy.
3. Have a heating system capacity not greater than
(17,000 Btu/hr) (5 kW) and a heating thermostat set-
point that is restricted to not more than 50oF (10'C)'
4. Have an average wall and roof U-factor less than 0'200
in Climate Zones I through 5 and less than}'I2} in Cli'
mate Zones 6 through 8.
5. Comply with the roof solar leflectance and thermal
emittance provisions fot Climate Zone I'
{.Section C402.1.2 is similar to Section C402-1.1 in
that it allows buildings to be exempt from the stan-
dard envelope provisions of the code, proÌided that
they meet ihe f¡ve criteria found here. Equipment
buiidings, shelters or sheds are installed to protect
electronic equipment from the weather and primarily
provide cool¡ng condit¡oning. Heating is installed for
êmergency baókup operation and must be limited to
50'F (10'C) or less by a setpoint. Due to the high
density of electronic equipment installed, heat is
rarely needed. The heat generated by the equipment
resuits in cooling being the key issue; therefore, pro-
viding less insulation is actually desirable from an
annual energy use standPoint.
This exemption is limited to stand-alone-equipment
buildings noi more than 500 square feet (50 m2) in
area. Simplified insulation requirements that apply to
an average of the roof and wall insulation are pro-
vided. Ttris type of building is often made with 3
inches (76 mm) of concrete, internal foam insulation
and a plywood interior with similar construction for
roof and walls. To reduce insulation requirements,
the ASHRAE 90.1 option may be pursued as the
building would qualify as a semiheated^ space. At
around 7 watts per square foot (75 Wm2) of equip-
ment load, the heat loss is offset by the equipment
load, with the proposed insulation resulting in very lit-
tle heating load.
It is important to note that this exemption applies
only to the building thermal envelope provisions. Any
HVAC, service water heating or lighting systems in
such buildings would still be required to meet the pro-
visions of the code.
C402.1.3 Insulation component R-value'based method.
Bwitcting thermal envelope opaque assemblies shall comply
with the requirements of Sections C402.2 and C402.4 based
on the climate zone specified in Chapter 3. For opaque por-
tions of the buitding thermal envelope intended to comply on
an insulation component R-value basis, the R-values for insu-
lation shall be not less than that specified in Table C402.1.3'
Commercial buildings or portions of commercial buildings
enclosing Group R occupancies shall use the R-values fro¡¡
the"Group R" column of Table C402.1'3. Commercial build-
ings or portions of commercial buildings enclosing occupan-
cies other than Group R shall use the R-values from the "{¡
other" column of Table C402.1'.3.
€.The code provides three methods to determine com-
pliance of the building thermal envelope. This section
ôutlines the compliance method based on the provi-
sion of insulation with R-values not less than that
specified in Table C402.1.3. The opaque portions of
the envelope (walls, roofs, floors and opaque non-
swinging doors) must comply with the requirements
of Séction 402.2 and Table C402.1.3, while the fen-
estration (windows, glazed wall systems and sky-
lights) must comply with Table C402.4. Commercial
OuitOings or portions of commercial buildings enclos-
ing Group R occupancies must use the R-values from
thé "Group R" column. Otherwise, the "All other" col-
umn must be used for the R-values to determine the
correct building thermal envelope. Group R is defined
in Chapter 2 ICEI to include the use of a building or
structure, or á portion thereof, including Groups R-1,
R-2. R-3 and R-4 as defined in the lnternational
auiiaing code@ (lBc@).
Some of the envelope requirements are based on
surface area. For instance, the glazing area is limited
to a percentage of the gross exterior wall area above
grade, and the skylight area is limited to a percentage
óf the gross roof area. The rules for measuring sur-
face aieas are summarized in Commentary Figure
C4021.3. See Section C402.4 for additional informa-
tion regardi ng fenestration.
C402,1.4 Assembly U-factoro C-factor or F'factor'based
method. Building thermal envelope opaque assemblies shall
meet the requirements of Sections C402.2 and C402.4 based
on the climáte zone specified in Chapter 3. Building thermal
envelope opaque assemblies intended to comply on an assem-
bly U-, C- or F-factor basis shall have a U-, C- ot F-factor not
grêater than that specified in Table C402.1'4' Commercial
buildings or portions of commercial buildings enclosing
Group R occupancies shall use the U-, C- or F-factor from the
"Group R" column of Table C402.1.4. Commercial buildings
or portions of commercial buildings enclosing occupancies
othèr than Group R shall use the IJ-, C- ot F-factor from the
"All other" column of Table C402.1.4
i. This section allows an assembly with a U-factor, C-fac-
tor or F{actor equal to or less than that specified in
Table C402.1.4 to be used in the design and construc-
tion instead of the R-values in Table C402.1.3. Com-
mercial buildings or portions of commercial buildings
containing a Group R occupancy must use the U-tfac'
tor, C-factor or F-factor from the "Group R"-column'
"Group R" is defined in Chapter 2 [CE] and includes
the use of a building or structure, or a portion thereof,
including Groups R-1, R-2, R-3 and R-4 as defined in
the lBC. This will ensure the correct building thermal
envelope will be determined.
Whereas the R-value table values refer to the R-val-
ues of the insulation materials alone, the U-factor
