STRUCTURAL COMMENTS
Geotechnical Report:
S-1 Please provide a copy of the project geotechnical report, sealed and signed by the
engineer in responsible charge, for review and verification of design values.
Structural Plan Comments:
S-2 Sheet S2.001: At the west end of the south primary structure foundation wall, section
3/S6.003 indicates that this condition does not achieve frost depth. Please revies.
S-3 Sheet S2.001: Between gridlines 3 and 4 at the west side of the foundation, section
6/S6.001 and associated grade beam note indicates it is not the intent to provide frost
depth. Please revise.
S-4 Sheet S2.001: Section 3/S6.001 at roughly A.2-2.2 indicates a new thickened slab
footing is to be doweled into the existing slab. Please verify the project geotechnical
report does not indicate that foundation elements are to be isolated from the slab-on-
grade. 4/16/2021

supporting the walkway from the primary structure to the garage similar to the column

S-6 Sheet S2.004: Please verify the garage ridge beam is sufficient with the applied 20 psf
DL + 70 psf SL.
S-7 Sheet S2.004: Moment frames are provided on gridlines 1 and 4. Please verify the drift
limits recommended in ASCE 7-10 Commentary Appendix C, Section CC.1.2 are met.
S-8 Sheet S6.001: Please verify if it is the design intent not to provide some kind of corrosion
protection for the steel in contact with soil below the slab-on-grade.
Structural Calculations:
S-9 Please provide a complete set of structural design calculations sealed and signed by the

MECHANICAL CODE COMMENTS
M-1 See Energy Code Comment #B3
PLUMBING CODE COMMENTS
P-1 None at this time
ENERGY CODE COMMENTS
EN-1 Refer to REScheck and architectural plans: The REScheck states that it is meeting
prescriptive requirements but also says that it is used to comply with the UA alternative
approach. You only need to comply with one pathway through the code. If you are
going prescriptive there is no need for a REScheck. If you are using the UA Alternative
approach, you must show how you exceed the prescriptive design by at least 2%
because the 2015 REScheck does not account for Aspen’s amended U-Factors for
windows (See IRC R402.1.5 as amended by the City of Aspen). Also, if you stay with
the REScheck, you will need to provide one just for the detached garage/ADU and then
one for the Duplex. You will need to include all components being constructed or
altered. The REScheck for the garage will be “new construction” and must include the
roof, walls, floors, windows, doors, etc. The REScheck for the duplex, if used, would
need to include the basement walls, windows, and any changes in roof insulation.
EN-2 Refer to current REScheck: It shows a roof insulation value of R49 +3continuous. The
roof details on Sheet A7.2, show one roof of R49 and one at R49 +10 for the flat roof.
Please split the square footages out in the RESchecks to account for each assembly.
