Subject: Building Plan Review
(1991 UBC with Oregon Amendments)
The plans for this project were reviewed for conformity with
applicable codes. Please submit the following items for completion
of the plan review process at your earliest convenience:
1. Since the occupant load for the lounge (room 227) is 61
per Table 33 -A, door 227B to swing in the direction of
exit travel (section 3304(b)).
2. Corridors serving an occupant load of 49 or less shall
not be less than 36 inches in width (section 3305(b)).
Please see the beginning of the corridor into stock room
260 at door 260B (sheet A9).
3. The children's sales area 258 requires two exits with a
maximum of 200 feet travel distance to an exterior exit
door, horizontal exit, exit passageway or an enclosed
stairway (section 3303(d)). Since escalators cannot be
used as required exits, the customer service area 255
would be required to be a one -hour fire -rated corridor to
stair 210.. Doors.258D, 252A, 214A, 212A, and 211A to be
20 minute fire -rated assemblies with smoke gaskets
(section 3305(g)(h)). A possible solution would be to
install a fire -rated door perpendicular to the corridor
side of the lounge to eliminate code problems in regards
to fire -rated corridors and.opening protection in the
customer service room.. In addition, the total occupant
load per Table .33 -A for the training room, offices,
customer - service area, and gift wrap room is 49,
requiring afire -rated corridor. .
4. When two or more exits are required from a room or area,
exit signs shall be installed at the required exits from
the room or area (section 3314(a)). Illuminated exit
13125 SW Hall Blvd., Tigard, OR 97223 (503) 639 -4171 TDD (503) 684 -2772
signs will be required at doors 227A and 227B, as the
•
occupant load for lounge 227 is 61 per Table 33 -A.
5. Doors 246C, 256A, 257B, 227A, and 122A to have a minimum
of an 18 inch strike edge wall (section 3109(H)3, figure
#25(a), and Table 31 -F).
6. Elevators 117 and 221 to have elevator lobbies per
section 3305(j).
7. Since this building is classified as 5N construction,
draft stops are required per section 2516(f). On the
other hand, if noncombustible construction is present
throughout this building, draft stops are not required.
Please clarify this issue /concern.
8. Fire dampers complying with the requirements of UBC
Standard No. 43 -7 shall be installed and be readily
accessible for servicing in the following locations:
1. Duct penetrations through shaft enclosures
(ducts penetrate the mechanical shafts without
fire dampers).
2. Duct penetrations through protective elements
of fire -rated corridor walls (see corridor area
of customer service 255, corridor area adjacent
to elevator 117, and corridor 233).
(section 4306(j) 3 and 5)
Please make these corrections on the appropriate pages of the
drawings and resubmit 3 copies of each page to the City of Tigard
for review.
