RE: Plan Check #: 2006-0845, 2007-1026, 2008-0073
Project: Old Milltown addition and major remodel
Project Address: 201 5th Ave S.
During review of the above noted revisions, it was found that the following information,
corrections, or clarifications are needed. Please provide written responses to each comment as to
how it has been addressed (support with code sections where applicable), and where changes can be
found on the plans. Please submit revised plans/documents to Theresa Umbaugh, Permit
Coordinator.
1) Please incorporate the redlines made on the original approved plans into the revised plans.
2) Coordinate occupant load calculations, restroom calculations, and ratio calculations on Sheet
A1.OA, with floor areas and occupant loads shown on the floor plans. Also, floor plans show
the existing basement and stair will be demolished which needs to be coordinated on A1.OA and
the opening schedule. Please coordinate.
3) New doors 48 and 62 must swing in the direction of travel and have panic hardware.
4) Where picture windows in storefront areas with louvers above changed to folding windows,
clarify note on floor plan which states "louvers above windows for ...relief..." as to what is
meant by relief so that exhaust air is not brought back into the building. Clearly note that all of
the louvers are for supply air only. Exhaust air terminations must meet IMC/WAC 501.5.
5) Note on the opening schedule for the folding windows that they must be safety glazed.
6) Provide accessible directional sign at exterior side of door 25 directing to door 22 entrance.
Also, dimension accessible clearance between post and building wall at grid F same location.
7) Continuity of 3 -hour Fire Wall along/near Grid H from foundation through the roof must be
coordinated between architecturals and structurals at approx. Grid 4.7 through to the south
exterior wall where it terminates. IBC 705
8) Revise section 5/A4.1 to show 3 hour Fire Wall from foundation through the roof at approx.
Grid 6.8.
9) At Grids 4.5 and between G & F, there needs to be a landing at the top and bottom of each ramp,
and where the ramp changes direction, a turning space is required. ICC/ANSI A117.1 section
405. Show elevation points at the landings and lengths of ramps so compliance can be verified.
10) Verify placement of building section lines so they are located at the actual cut you are trying to
show.
11) Clarify if the proposed mechanical louvers on the south side are providing supply or exhaust air.
Justify their size and distance to fire separation yard per IBC 704.8
12) Show the property line on the construction details of the proposed trellis and louver projections
Sheet A2.7 and show that it meets IBC 704.2. Exhaust terminations must also meet State
Amendment to IMC 501.5. Supply intake openings must meet IMC 401.5 and 401.5.1.
13) Add vertical grab bars to the accessible toilet details Sheet A2.3 (ICC/ANSI 604.5.1).
14) Note on detail F7/A2.5 that the residential occupancy is "future" and provide details showing
how the roof assembly of the second floor will meet code until the "future" addition is approved
and constructed. -
15) On Detail 12/A2.7, clearly show that the cross -slope of the ramp run to the sidewalk will not
exceed 1:48. Provide sections to clarify. ICC/ANSI Al 17.1 section 405.3 Also note that the
vault lid will be flush with the floor surface.
16) Approved special inspector (for structural items) per the agreement filed with the building
permit is Mayes Testing, however special inspection reports are being submitted by Cascade
Testing Laboratory. A new Special Inspection and Testing Agreement must be submitted.
Complete the enclosed agreement, have the owner, general contractor and special inspector sign
the form and return for approval within 10 working days of the date of this letter.
17) We are still reviewing the intumescent paint issue and will notify you as soon as we have
finished. In the meantime, assuming it is approved, add intumescent paint to the list of Special
Inspections and to the Special Inspection Agreement.
18) Mechanical plans require a "90% free area open door" at the wood gate screen on the north side
of the building. Revise 1/A2.4 to show minimum opening % and coordinate with mechanical
engineer for minimum net free opening requirements.
19) Please bubble all of the specific changes throughout the revised set of plans, including the
schedules so that we are sure we have reviewed all changes. The current approved plans include
revision #3 & 4, so 5, 6, 7, & 8 must all be included in this set.
Shelf/Core plumbing 2008-0073
20) Show location of condensate drains required for mechanical equipment as noted on the
mechanical plans.
Mechanical 2007-1026
21) Incorporate latest architectural floor plan revisions.
22) Exhaust termination/louvers for the ventilation system must be at least 3 feet from intake
louvers and building openings. Provide and elevation view specifically showing this
requirement and coordinate with the architectural plans. State Amendment to IMC 501.5
23) See #12 above in architectural comments. Coordinate with architect and add needed
information for mechanical openings.
24) Provide ventilation (supply and return) for the corridor.
25) Show the complete ventilation system (supply inlets and exhaust outlets) east of the 3 hour fire
wall. Coordinate with architecturals.
26) Manufacturer's combustion air information for the A.O Smith boilers notes standard combustion
air requirements with high/low openings, however the plans note one 4" duct for each unit.
Provide manufacturers information for this method of supplying combustion air.
27) Specify minimum net free opening requirement for wood gate screen on north side of building.
Coordinate with architecturals.
