Removal of ADA ramp at east courtyard
Portland Dan,
Seattle
Sacramento There is an ADA ramp shown at the east courtyard entrance on C2.2. Although
Irvine shown on the plans, we do not intend to build this ramp, but will grade and make
allowances for it in the future.
This is a secondary entrance to the ground floor. The main entrance is through the
main lobby and down the provided elevator and stairs. The egress of the building
does not require this exit. It is intended to be a secondary entrance and amenity to
any tenant who is located at the entry doors.
During our plan review on Tuesday 7/21/09, you agreed that his is not a required
accessible exit. We will not be building it in phase 1, and will only do so if the
occupying tenant wishes to have a ramp.
Attached is a revised accessibility worksheet. We are doing significant
improvements to the parking, site entry and bathrooms which currently do not meet
accessibility requirements. The deletion of this ramp still maintains a threshold of
over 25% of work to be done to remove barriers.
Please consider that the ramp is deleted from the plans or is a "future phase” during
your review.
Thank you,

fire rating

Dan,
I did some more looking into the fire rating
requirement within the main lobby space and I
believe that the code may allow for provisions that
do not require we rate the construction of the walls
internal to the lobby enclosure (ie toilet rooms,
janitors room, electrical room, etc). I have
attached a copy of the 2006 IBC Commentary,
apparently our office does not have a copy of the
2007 OSSC Commentary, but in looking at
previous versions it appears the same response
was given to this sections, so my assumption is
that it has not changed. This section states that
"The lobby, all other areas on the same level that
are not separated from the lobby by fire barriers
consistent with the rating of the stair enclosure,
must be sprinklered in accordance with NFPA 13.
If the entire level is sprinklered, no separation is
required ". There is a requirement that the
lobby floor and supporting construction must be
rated the same as the stairway enclosure to
prevent a fire from mitigating up to the lobby from
the floor below.
believe that this clause allows us to construct all
the new walls and doors for the toilet rooms and
other incidental spaces within the lobby as non-
rated construction as long as we provide sprinklers
throughout these spaces, which is what I believe
we are doing anyway. Beyond the lobby area in
question we would provide a 2hr separation
between the office space and the lobby. At that
point, only the stairway enclosure walls and door,
elevator and mechanical shaft walls, and the wall,
door and relight separating the lobby from the rest
of the office space would need to conform to 2 hr
construction. Doors within these walls would
1
be 90 minute doors. This appears to match what
we proposed on our initial plan that was submitted.
I think then we'd just need to confirm the rated
assembly of the existing 2hr walls,confirm that the
concrete floor thickness achieves the 2hr rating
and make sure that all penentrations in the floor
are properly equipped with fire and smoke
dampers as needed.
I'm working on the wall assembly portion of this,
and will try and get something to you by tomorrow
morning.
Let me know what you think.
Thanks,
Scott
