During review of the plans for the above noted project, it was found that the following information,
clarifications or changes are needed. Please provide written responses as to where the changes can be
found on the plans, and submit revised plans/documents to a permit coordinator in the Development
Services Department. Thank you.
General
1.Please provide calculations and design details for the seismic anchorage of rooftop equipment
weighing more than 400 pounds. (All RTUs and MUA-1) The documents must be stamped
and signed by a Washington state licensed engineer.
2.On the HVAC floor plans, please show the reference callouts for the applicable details that
are shown on sheets M4.0 and M4.1.
3.The notes on sheet M1.0 state that smoke fire dampers are to be installed where ducts
penetrate fire and smoke rated assemblies, and there appear to be a large number of these
locations. Please show these locations on the HVAC floor plans, including ceiling dampers,
either by symbol, notation or referenced callouts.
4.Add a note on the plans that the med gas system is to be verified by a third party agency
according to UPC 1327.
Sheet M-1.3
5.Please indicate which fixtures will require backflow prevention devices and what devices will
be used. UPC 103.2.2 and 603.1
Sheet M-2.2
6.Add a note as to the location of the reference key and equipment schedule for the circled
callouts in the kitchen, or include the information on sheet M2.2.
7.Please provide an enlarged/enhanced kitchen drainage plan. Revise the drainage plan to
discharge fixtures into the grease interceptor or directly to sanitary sewer as appropriate, and
according to comments from Les Krestel, Wastewater Treatment Technician.
Sheet M2.10
8.What is the symbol MAP/1 shown in Nurse Station 130?
Sheet M3.2
9.A Type 2 exhaust hood is required over the warewasher. Provide details and CFM for this
hood. IMC 507.2.2
10.Clearly show the locations of the kitchen exhaust hoods on the plans. I suggest this
information would be helpful if shown on sheets M3.2 and FS1.
11.The med gas room is shown to be exhausted by a 50 cfm fan, through a 6x4 wrapped duct up
to roof cap. Please provide a design for the wrap to show how it complies with the shaft
requirement of IMC 502.9.1
12.Provide a supply duct to the med gas room complying with the requirements of IMC 502.9.1.
Sheet M3.6
13.On the Roof Plan, provide at least 10 feet of separation between the kitchen exhaust fans and
any other equipment with air intake, or show how it meets the exception to IMC 506.3.13.3.
Sheet M3.8
14.The size of the dryer exhaust duct on the roof plan does not match that in detail 6/M4.0.
Please coordinate.
15.How will the grease ducts be separated from combustible materials as per IMC 506.3.6? The
note on detail 5/M4.1 states: See Captive Aire detail on MX.XX for duct detail but a detail
is not provided. Please clarify.
16.Drawing #2 on M4.2 notes 1 inch layer of insulation meets 0 inch requirements for clearance
to combustible surfaces. Please provide the mechanical code section or other approved
agency listing to show how this detail complies with IMC 507.9.
17.The appliances under the Type 1 hood are listed as a gas range, broiler, griddle, and oven, and
these appear to be medium duty or even heavy duty appliances by definition in IMC 202, and
need at least 300 cfm or 400 cfm, respectively. Please clarify, and modify the plans as needed.
