Mechanical Permit Review 02
I have received and reviewed the above referenced project for conformance with the
following codes, as adopted and amended by the State of Washington and the City of
Edmonds:
2015 International Mechanical Code (IMC)
2015 International Fuel Gas Code (IFGC)
2015 Uniform Plumbing Code (UPC)
2015 Washington State Energy Code, WAC 51-11 (WSEC)
The comments listed below only apply to the documents submitted with the building
permit application for the mechanical and plumbing reviews (medical gas systems have
not been reviewed):
1. Resubmit the Washington State Energy Code Compliance Forms using the 2015
forms. I acknowledge that there was a long delay waiting for current forms to be
made available, but at this juncture we are able to utilize the correct forms. Please
note that specifications are not reviewed; items listed as being required to be
indicated on the plans need to be included in the plan set.
Metrix: At the time of permit submission, the 2015 NREC forms were not available.
The NEEC website required that the 2012 NREC forms were to be used until the
2015 forms were available. The information contained in the 2012 NREC forms is the
same as the 2015 NREC form, other than the additional DOAS requirements, which
is not required for this project being that it will be permitted prior to when the DOAS
requirement goes into effect July 2017. The review process shall remain the same.
There is ample time to provide the current 2015 WSEC forms and they are
required for this permit submittal. As noted in the first review, specifications
are not reviewed; items listed as being required to be indicated on the plans
need to be included in the plan set.
2. Sheet M-001: Indicate on this sheet that the design meets the requirements of the
2015 IMC, 2015 IFGC, 2015 UPC, 2015 WSEC, and all local code amendments.

both on plan.
10. Sheet M-322: The requirements for commercial kitchen hoods are governed by the
IMC and including the hood information as for-reference-only is not adequate.
Include a hood schedule in the mechanical plans. Be sure to indicate hood listings by
rating agencies, hood material and gage.
Metrix: See attached XK-201 kitchen canopy hood details sheet. Hood is not
provided by mechanical contractor will be provided by others.
Who is providing the hoods is not an issue; the kitchen hoods need to be
included in a mechanical permit review. That can either be part of this review or
be submitted under a separate permit submittal.
11. Provide specifications for the fume hood.
Metrix: See attached plumbing fixture spec 22 40 00: P-9 for basis of design fume
hood.
Following review of the fume hood spec sheet, please verify exhaust air flow
rate for the exhaust fan matches the specified hood.
