Dear Mr. Koldeway,
The County Building Department has performed the review on the building permit application
and plans for the new Aircraft Hanger 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 drawings, with clouded areas reflecting any
changes from the original submittal and a thumb drive with a complete set of the drawings.

Note: The lnternational Building Codes are the adopted and enforced codes within the county.Only the Standards.that are specifically being referenced within the Building Codes are utilizedWith that.said, only the specific sections of the standards that are being ref6renced are takeninto consideration. For example, the entire NFPA 409 does not apply o-nty tne referenced
seotions do, as there are conflicts betweerr the l-Codes and the NFPA 4dg StanOarO.
corrections to address prior to issuinq a building permit:
t{!\e^aylitectural_hard copy of the drawings have a notation stating, 'pRELlMlNARY NOTFOR CONSTRUCTION". The structuralsheets have a notation stJ{ing, "PROGRESS - NOTFOR CONSTRUCTION". None of the sheets within the physical sets ire stamped by thedesign professionals. The digital sets provided do not have the notations and are stimped. Iam continuing the review as the digital revision log is identicalto the physical set. When thephysical drawings are resubmitted, the "not for construction" notationb jre to be removed,
and all sheets are to be stamped by the design professionals in responsible charge. (lBC'

HAUSER: noted
IMEG: Drawings will be stamped by a professional and "not for construction', will beremoved prior to resubmittal.
PEAK: Ditto
t/ NFPA 409 designatesthe Group Classification for hangers. This hanger is being proposed
as a Group ll Hanger. That designation requires the hanger doors to 6e 28' or lJss. The
elevation drawings states "30' min. door height" but the steel drawings from NUCOR
indicates 28' o_pening height. Please change the etevation drawingsio comply with a Groupll Hanger. (lBC 412.4, NFPA 409 Table 6.1.2)
HAUSER: The design incorporates a 30' high door assembly that includes a 2, high
ffuturel removable !91der panel, which is flxed in place actoss the top of the opjningand is part of the PEMB structure. This configuration creates a 28' high '.aircraft
access door height".
Our interpretation of NFPA 409 is that the 28' door height limitation for a Group llHangar specifically refers to the size of the clear opening for aircraft access, ratherthan the overall height of the door system's components. We believe the standardemphasizes "aircraft access" as the critical wording. Our design incorporates a fixed,clear vertical opening ol28'which we believe align- with the p-rescriptive
requirements of the code and helps uphold the intended safeiy standards.
Th_is design approach is a common and accepted method within the industry. lteffeetively meets the fire protectlon lntent of ihe current code (whie h is to limit thevertical opening size) while also providing the facility owner with future flexibility tooperate larger planes should code requirements change where an increase in doorheighUopening does not require the use of a foam tire-suppression system.
