RE: Plan Check: BLD20090150
Project: Edmonds Dental Implant Center
Project Address: 22727 Highway 99, Suite 209
During the second review of the resubmitted 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.
1. In the original letter dated 212412009, item number 3, you were asked to show the accessible
route to the tenant space, proposed accessible upgrades to the existing route, and the 20%
exception of IBC 3409.7. Based on the information provided by the architect of record, the
building is "fully accessible". In order for the route second floor to be considered accessible,
either the elevator has to meet todays accessibility standards, or the stairs would need to be
accessible. For the elevator to meet the accessibility standards of today, a number of upgrades
will likely have to have been recently made, including but not limited to:
a. Standby power per [F]2702.2.5
b. Accessible Signage
c. Accessible controls
d. Accessible interior elevator dimensions
e. Accessible grab bars
2. If the stairs are to be used for an accessible route a number of items will have to be completed,
including but not limited to:
a. 48 " clear between handrails
b. an area of rescue at the top of the stairs with
c. communication requirements
d. signage requirements
3. When alterations to existing buildings are performed and the building is not yet accessible,
there is an exception to limit the costs for upgrading the accessible route to 20% of the costs
of the alterations per WAC 51-50, 3409.7 exception 1. This is what I was referring to with
my first letter, item number 3. Instead of trying to upgrade the whole route, I would like to
make the following suggestions for upgrades. If you would like to propose some or all of
these as the required max 20% upgrade you will need to propose them with a corresponding
estimated line item costs, that we can then compare with the estimated $51,300 project cost,
to see the relationship to the 20% of costs.
a. According to IBC T 1106.1 a parking lot with 51 to 75 parking stalls will require 3
accessible parking stalls, with one of them required to be van accessible. If your
parking meets with planning approval as stated on the plans, it appears that there
would be a couple of extra parking spaces, and one could be converted to a van
accessible parking stall, per ICC/A177.1- 502.2. This would probably eliminate one
parking stall. The stall can be 11' wide with a 5' access aisle, or 8'wide with an 8'
access aisle. This would be located on the shortest route to the accessible entrance,
and have curb ramps as necessary.
b. Change the old ADA parking signs to be a minimum 50" to the bottom of the sign (if
that hasn't already been done).
c. Change the existing entry door hardware to the lever handle.
4. The response to former item number 10 states that an RPBA will be installed at the water
meter. The premise isolation must be in a Hot Box at the meter location. Attached to this
letter you will find E7.11, a standard detail for a "hot box assembly", for that application.
Include this detail with your plans.
