Plan Review Comment Responses
City of Tigard Permit Number- BUP2017-00019
Project No.: 17857
Below is a list of the River Terrace Apartments Building A Plan Review Comments from you dated
April 27,2017. The original revised comments are in italics followed by our response in bold type.
The original comments are also attached for reference. Revisions for these comment responses
below are bubbled and called out with a Revision #2. There are some drawing coordination
revisions which are bubbled and called out with a Revision #1.
1. Provide 1h doors from three story stairway to corridors.
Response: Per OSSC Table 716.5 the 1-hour walls of the stairway are required to have
a 1-hour door (60-minute) rating instead of 20 minutes as noted on our door
schedule. Door A10 has been revised to have a 60-minute rating on the door
schedule of Sheet A1.11 as well as in the hardware schedule for Group #2. (As a part
of project coordination, a note for a magnetic hold open was also added to these door
comments of the schedule to call attention to it in the hardware groups also on Sheet
A1.11.)
2. Provide 45 min. doors from garage to corridor.
Response: Per OSSC Table 716.5 the 1-hour walls of the corridor are required to have
a 3/4-hour rating (45-minute). Door A4 has been revised to have a 45-minute rating
on the door schedule of Sheet A1.11 as well as in the hardware schedule for Group #3.

3. Show protection at stairway walls within 10 ft of openings. OSSC 1022.7
Response: Instead of protection of the walls within 10 feet of the openings we
provided an extension of the fire resistive walls of the stairways to the exterior stair
wall containing openings alleviating the requirements of OSSC 1022.7. This was
taken care of by creating 2 new walls assemblies,1-hour Assemblies #12A& 13A.
These assemblies have been called out on the stair plans appropriately on Sheet
A5.01 as well as on the first floor building plan of Sheet A2.01 to correct wall
assemblies that did not coordinate with Sheet A5.01.
4. Please indicate on plans need for stairway marking. 1022.9.
Response: Requirements of OSSC 1022.9 note that stairs not connecting more than 3
levels are not required to provide the signage per OSSC 1022.9 No changes have been
made to the construction documents as a result.
5. All fire barrier and partition doors shall be self closing as per OSSC 716.5.9.
Response: The note "SELF CLOSING" has been added to the door comments of
doors A4 - Garage Entry,A5—Corridor,A10- Stair and B1-Unit Entry of the door
schedule on Sheet A1.11. The door hardware of each of these doors has also been
confirmed to have devices to make them self-closing (closers or spring hinges)
currently to meet the requirements of OSSC 716.5.9 to be self-closing. (Many of the
doors currently employ spring hinges to enable the doors to be self closing. Per your
April 27th phone conversation with Wayne Yoshimura of our office, spring hinges
were noted to be acceptable devices to employ for self-closing doors.)
6. Accessible baths in type "A"units shall comply with ANSI 404.2.3.
Response: Building A does not contain any Type A accessible units and therefore no
revisions to the construction documents are required as a result.
7. Please show air gap under siding as per OSSC 1403.2.
Response: Details on Sheet A8.01- 05 generally either show the presence of a
weather resistive barrier covered with rainscreen furring to provide the air gap of
OSSC 1403.2 which is then covered with exterior siding material or they show the
presence of a weather resistive barrier and air gap/space of OSSC 1403.2 which is
then covered with veneer brick. Detail#13 on Sheet A8.01, Details #10, 12, 18, 19 on

Sheet A8.02, Details #1,3, 7, 14, 18 on Sheet A8.03, Details #1,3, 9, 15, 17, 18, 19 on
Sheet A8.04 and Detail#1 on Sheet A8.05 have been revised to clearly delineate the
rainscreen system with weather resistive barrier to provide a drainage pathway for
water entering the system to drain out and air to dry the system.
8. Please change language in plans from passageway to corridor.
Response: "EXIT PASSAGEWAY" designations of Code Plan 1 of Sheet A0.10 has
been changed to "CORRIDOR". The rest of the plan set already notes corridors at
all levels.

Response: Those areas are attached to these responses from an email sent to you
earlier by from us at Otak.
