Demo/Existing Conditions Observation
675 East Durant Avenue- Aspen, Colorado 81611
ESD Project#: 22.146C
Philippe-Antoine,
As requested, Evolve Structural Design conducted an observation of the Demo/Existing Conditions at the
location noted above on Wednesday, May 3, 2023. Our review was based upon the original structural plans
prepared by Hagman Yaw Architects, LTD as well as the Pricing Set of architectural drawings (Sheets 100, 120
and 120) provided by Poss Architecture+ Planning, dated June 29, 2022. Please note that this review was
limited to the scope of work noted in these plans.
Based on this observation, it is our opinion that the demolition, as observed, is limited to light framed interior
partition walls that do not impact the existing structure as all structural elements are retained as shown in the
above noted plans. In regard to the existing structure, the concrete foundation walls, steel beams and columns,
and underside of the concrete pan deck appeared to be in good condition with no apparent signs of distress (i.e.
cracking, settling/movement or excessive deflection). Additionally, there were no apparent signs of moisture or
other damage observed in this area.
During this observation, the Project Superintendent, Tim Thornell with Shaw Construction, requested that we
review a 14" round mechanical penetration which is to occur in two locations, both through existing CMU
partition walls (i.e. non-bearing walls) enclosing the V.V.T. Rooms associated with this area. The first is at the
top of the CMU wall on Grid-Line 1, approximately 13'-6" north of Grid-Line C directly below the existing
structural steel beam above. The second is outside the area noted but across from the first location, on the
opposite side of the parking garage ramp, and is to be located approximately 4'-6" from the outside corner of
the wall at approximately the same elevation as the other mechanical penetrations currently in this area. In
both cases,the requested penetration is allowable and will not adversely affect the existing structural
performance of the building. New penetrations shall be cut in the approximate location noted above and
spaced 16" minimum from any existing penetration in either CMU wall in a way that does not compromise the
integrity of the wall.
Please note, to date, Evolve Structural Design has not performed any in-depth analysis of the existing structure
to verify compliance of the structure with current building codes or other standards. Furthermore, the opinions
expressed herein are based on limited observations and information provided, as noted within. No expressed or
implied warranties or guarantees of any kind, nor assurances of future performance are given. If additional
documentation or knowledge of structural/building conditions becomes available that differs or expands from

that mentioned herein, we shall be contacted to reassess, and reserve the right to amend our opinions and
report accordingly.
Should you have any further questions at this time, please feel free to contact our office.
