Re: Charthouse Lodge New Mechanical Units
Dear Mr. Frye,
The purpose of this letter is to state that we have reviewed the existing roof structure of the
building located at 219 East Durant Avenue in Aspen, CO for support of a make-up air unit. Our
review consisted of the following: review of the proposed mechanical equipment provided by
MKK Consulting Engineers, Inc., review of the existing structural drawings, and structural
calculations.
The existing roof structure is metal roof deck over steel framing supported on steel columns.
Existing roof members in the area of interest were W12x14 and W14x22 beams and W12X14 and
W16X26 girders. Existing beams were spanning 23’-6” and spaced at 6’-0” OC. Existing girders
spanned 18’-0”. The existing framing was checked for a roof dead load of 15psf, snow load of
75psf, and the additional mechanical loads. Based on our calculations and experience, the
existing roof structure is adequate to support the mechanical equipment provided it is located as
indicated by MKK.
This review was prepared in accordance with the standard of care for engineering practice. No
warranties are provided, either express or denied.
If you have any questions, please feel free to call.
Sincerely,
