Re: Residential Remodel: Unit 3C North of Nell FORCOMCUMPLIANCE
555 East Durant Street, Aspen, CO. justinh
Our office has reviewed plans for the proposed remodel project at the noted third
and fourth floor North of Nell units. Our office has provided structural design services for
a number of projects at the North of Nell building. Most recently was the 2021 remodel
of Unit 2B. Most significantly was a 2009 maintenance project which involved a
replacement roof and new guard rails for the exterior decks.
We have completed a review of interior demolition plans and remodel plans for the
noted unit (Architectural `Permit Set' (June 16, 2022)by Thunderbowl Architects. Based
upon our understanding of the building's structural framing, the present architectural
proposal does not impact the building's framing systems in any negative manner.
Consequently, it is my professional opinion that the proposed project can safely proceed
with appropriate safety protocol measures and structural inspection services.
Note that the structural framing system is based upon structural steel frames (Steel
column and beam lines) spaced at approximately 19 feet on center and wood sawn 2 x 12
rafters and floor joists spanning frame to frame. For a majority of the building the steel
framing runs east-to-west (along the length of the building) and the rafters and floor joists
span north-to-south. During the demolition and de-construction phase the contractor
should take care to leave all structural steel elements in place and undamaged. Any
modification to the relatively long span 2 x 12 framing will require structural analysis.
Our office recommends that we perform a structural inspection of the exposed
framing during the demolition and deconstruction phase. Given the age of the building
and the relatively long joists and rafters, individual joists and rafters may require rein-
forcement. During the remodel phase any plumbing or HVAC work which impacts the
framing systems should be evaluated by our office. Please call if you have any questions.
