Re: Green Office Building, SW 67` Avenue and SW Atlanta
Dear Mr. Lampella:
On behalf of Joe Green, Jr., we request approval of plan modifications to above
referenced office building. To accommodate symmetrical design considerations in the
Gallery, and to avoid reversing the plumbing and restroom arrangements, we wish to
relocate the pair of doors, number 7, on floors 2 and 3 to positions directly above the pair
of doors, number 6, on the first floor, approximately at the center of the building. These
doors will be changed to bi -swing doors, number 6, as they are on the first floor. The exit
passageway and doors on the first floor will not change.
Alternative construction and door location were revised from the original plans for
creation of exit passageways on each of the floors. Only the first floor was modified to
have restrooms entering into the exit passageway. This alternative to code requirements
was approved by the City of Tigard in response to our letter dated October 25, 2003. The
same measures will be observed in the relocation of the doors on the second and third
floors.
As on the First floor, the restrooms on the second and third floor in this proposed revision
enter onto the proposed Exit Passageway. As an alternative to the requirement of
1005.3.4.4, these rooms will be protected by two -hour fire rated wall construction of 2x4
wood studs at 16" O.C. covered with two layers of type X gypsum board (GA File No.
WP 4136) and a floor ceiling assembly of T & G sheathing over TJI joists and 5/8" •
gypsum board ceiling supported by resilient channels. NER -200 ASSEMBLY E -7 and
the doors will be 90- minute fire and S rated.
The building is protected by an automatic sprinkler system, not otherwise required by
code. This measure further adds to the equivalency of the above proposed alternatives.
Smoke detection is proposed only for automatic door release and alarm annunciation only
as required by NFPA for fire sprinklers.
