RE: Plan Check #2007-0071
Project: Steele Home Services -- Interior and Exterior Remodel
Project Address: 23631 Highway 99
During review of the plans for the above noted project, it was found that the following information,
clarifications or changes are needed. Provide written responses to each comment and where changes can be
found on the plans. Submit revised plans/documents to Theresa Umbaugh, Permit Coordinator. Please call
me if you have questions, or please call in advance to schedule an appointment.
1. Note the scale of the floor plan and revise the plan to meet that scale. For example, it appears the plan is
drawn at 3116"=1' however the ramp is not drawn entirely to scale.
2. The I -hour fire separation must be maintained separating the garage from the B occupancy. The wall
infill must be I -hour rated (provide detail) and the door must be self-closing 3/a hour rated. Please show
on plans.
3. Accessible ramp (ICC/ANSI Al 17.1 section 405 --- a copy has been provided for your use):
a. Coordinate ramp floor and framing plans to match (for example, ramp length, landing size, etc.).
b. Ramp landings must have a minimum 60" minimum circular turning space. Please show on the
floor and framing plans.
c. On the floor and framing plans dimension the width of each section of ramp.
d. Dimension the length in the direction of travel of the bottom ramp landing (the adjacent stairway
and handrail cannot encroach into the minimum landing size).
e. In calculating the slope of the ramp, given the top and bottom elevations shown on the floor plan
and the length of the ramps at maximum 1:12 slope, the maximum permitted ramp slope will be
exceeded. Provide the elevation points for each landing. Based on the current plan starting at the
top of the ramp 103'8" - 1 l"=10259" — 5"=10254" — 8" = 101'8" which exceeds the bottom ramp
elevation shown on the plans by 3". Please revise and coordinate with framing plan.
f. On ramp detail A sheet 3, dimension the maximum distance from the ramp or landing to grade. If it
exceeds 30", a complying 42" high guardrail is required in addition to the handrail.
g. On the north and west elevation views of the ramp, where the ramp is provided with 2 rails, the
bottom rail must be 4" above the ramp/landing surface for edge protection (Section 405.9)
h. Revise depth of footings to minimum 12".
4. Provide accessible shower details showing compliance to ICC/ANSI Al 17.1 section 608 (copy provided
for your use). If the shower will be prefab, a manufacturer's cut sheet can be provided which shows
compliance.
5. On the site plan, show the location of the accessible parking sign at the head of the accessible parking
stall.
6. Door from coffee room to garage must have a complying landing (36"x36"). If this requires the
stairway to be rebuilt, it must comply with current code (rise, run, handrails both sides, handrail
extensions, width, etc.)
7. Note the width of the door to the front office.
8. Handrails are required on both sides of all stairways.
9. Clarify/dimension handrail detail 1 on Sheet 2 to show it will meet IBC 1009.11. Since it will not be
circular, it must have a perimeter dimension of 4" minimum and 6.25" maximum with a maximum cross-
section of 2.25".
10. Show how ventilation is provided to the offices, show room and coffee room either mechanically or with
natural ventilation using building openings (windows and doors) in accordance with the State
Ventilation Indoor Air Quality Code.
a. Natural ventilation: Provide in each room or area at the rate 4% of the floor area. Show the
calculations on the plans, and show all openable area of windows/doors on the plans. OR
b. Mechanical ventilation: Provide outdoor air at the rates specified in VIAQ Table 34 (based on the
occupant load established for the building) to each room or area. The system must be balanced
(supply and retum/exhaust). Provide mechanical plans and calculations showing compliance.
Provide manufacturer's specs for the mechanical units to be installed.
11. Revise "applicable codes" on Sheet 3 as follows:
a. 2003 International Building Code (including Accessibility) with State Amendments
b. 2003 International Mechanical Code (including International Fuel Gas Code) with State
Amendments
c. 2003 International Fire Code with State Amendments
d. 2003 Uniform Plumbing Code with State Amendments
e. 2004 Washington State Energy Code (WAC 51-11)
f. 2003 Washington State Ventilation Indoor Air Quality Code (WAC 51-13)
g. 2002 National Electrical Code with State Amendments
