1. Appeal of 12-7-50
 

State of Oregon by State Board of Higher Education.  This appeal involves installation of suspended ceilings in two rooms of the present Lincoln High School at 1620 S.W. Park.

    The letter of appeal, signed by Clarence H. Wick, reads as follows:

    The State of Oregon, acting through the Oregon State Board of Higher Education, owners, of the Lincoln High School Building located at 1620 SW Park Avenue, Portland, Oregon, propose to improve Rooms 106 and 113.

    The improvements consist of installing a suspended ceiling with fireproof acoustical tile and new light fixtures.  The suspended ceiling is to be supported by metal supports as required by Section 7-2804 of the Portland Building Code.  Dantore incombustible acoustical tile is to be supported by Tee bars attached to the furring channels.  Light fixtures to be suspended approximately 3' from ceiling.

    The existing ceiling heightis approximately 16'5" between beams.  The present ceiling is plaster on 5" hollow clay tile with a 2" thick concrete slab over the tile.

    The proposed suspended ceiling height will be approximately 14'.  The suspended ceilings will enclose a dead air space free from heat ducts, pipes, etc.  All electric work will be in conduit and in accordance with the Portland Electric Code.  On behalf of the owners we ask relief in complying with Sec 7-2804 B.C. requiring metal lath and plaster, and be permitted to use the system described above.

    The checking sheet, prepared by Mr. Worthington, sets forth as follows:

    The applicant wishes to construct suspended ceilings in 2 areas totaling approximately 1680 sq. ft.  This ceiling is to be supported in accordance with Sec 7-2804 B.C. but no plaster on metal lath is proposed.  In lieu of plaster the applicant wishes to apply an incombustible tile direct to the furring channels.  The floor above the area in question is of incombustible material and the requirement of fire protection is not involved.

    Plans were spread before the members.

    Mr. Newberry:  This is the same as in the Lewis Building; our code says metal lath and plaster for suspended ceiling; appellants plan to use Dantore incombustible acoustical tile hung on T bars; there is nothing wrong with it.

    Mr. Settergren asked Chief Woodworth if has has any objections.  Chief Woodworth replied, no.

    Mr. Newberry moved:

      That the appeal be granted.
Mr. Settergren seconded the motion.  The motion was unanimously carried.  The $10 deposit fee is to be returned to appellant.

2. Appeal of 7-16-53

    Portland State Extension Center remodeling - This appeal involves suspended ceilings in various rooms in appellant's building at 1620 S.W. Park.  The letter of appeal and check sheet read as follows:

The State of Oregon acting through the Oregon State Board of Higher Education, owners of the Portland State Extension Center Building located at 1620 S.W. Park Avenue, Portland, Oregon, is renovating and altering many rooms in the referenced building.

4. Appeal of 6-16-55

    Oregon State System of Higher Education - Portland State College.   This appeal involves classroom buildng to be erected at 1620 S.W. Park.

    The letter of appeal and check sheet read as follows:

Letter of appeal - Portland State College - 1620 SW Park - covered bridge, exit stairs, temporary penthouse, fire escape, basement classroom.
--------------------------------------------------

    In the design for a classroom building for Portland State College, we have found it necessary to violate certain sections of the Portland Building Code.  The Bureau of Buildings has been very cooperative in checking our preliminary drawings, so we could appeal at this time.

A. The following are violations of Section 7-2003 and 7-2005:

    1. We are at the present time seeking a city ordinance to permit our bridging Mill Street to connect to the existing classroom building (old Lincoln High School).  This bridge is at one level only, the third floor which is approximately 40' above the street, and is used for student traffic only.  In order to minimize the weight of the structure we have proposed that the truss members be exposed on the interior, the exterior being covered with an Underwriters approved 2-hour aluminum covered curtain wall, and corrugated wire glass.  The underside of the structure fireproofed with cement plaster on metal lath.  The steel deck covered with a fiber glass roof insulation and built-up roofing.  Class "A" fire doors close off each end of the bridge from the connecting buildings.

    2. Because this initial building is only a quarter of the overall plan, a temporary exit stair is located on the S.W. corner.  This stair has been designed as an unfireproofed steel stair with a sheet steel siding enclosure.  The reason for enclosure is both as weather protection and for control.  The State System of Higher Education owns the adjacent property.

    3. Because the design anticipates 3 additional stories we are requesting that the elevator and mechanical penthouse be allowed to be constructed of unfireproofed steel covered with sheet steel siding.

B. In lieu of a fire escape required by Section 7-5201 in this initial quarter or additional ones in the future, we developed a modified smoke tower.  This consists of a masonry enclosed stair with access only from a vestibule (except on ground floor).  The vestibule connects the stair tower and corridor, and also has a door leading from the outside, off which is a platform for firemen, a ladder and stand pipe.  This door is operable from the outside at all times.  Above the door is a louver of adequate size and open to the exterior at all times.  In addition a vent shaft, with a grille opening near the ceiling, is to be connected to a mechanical fan which will go in operation if the alarm is sounded.  Both the stair and vestibule doors are Class "B", provided with door checks, push and pulls, but no latches.
Both Chief Gilman and Mr. Gilson, Deputy State Fire Marshal, have been consulted on this design.

C. The ground floor of this building is between one and eight feet below ground, due to the grade condition.  This floor is designed for use of classrooms and laboratory, with only the laboratory having windows - and these relatively small.  As the whole building is designed for mechanical ventilation, and a preference has been expressed for interior classrooms for some purpose, we do not believe the technical violation of section 7-4203 is serious.

                                            Lawrence, Tucker & Wallmann
                                            (signed) G. R. Wallmann

                                   ****************************

    Preliminary plans were spread before the members.

    Item 1 - bridge - was discussed.  Mr. Wallmann stated this bridge will be 40 feet above the street, and approximately 60 feet long;  there will be just one deck.  Mr. Bruun said aluminum panels have been used for enclosing fire escapes with the same type of panels.  Chief Gilman said he cannot envision a hazardous condition if the underside is protected.  Mr. Newberry said so long as the underside is fireproofed he has no objection.

    It was unanimously agreed to approve Item 1.

    Item 2 - exit stair with sheet steel enclosure was discussed.  Mr. Wallmann stated this is only a temporary exit stair;  they wish to enclose it with sheet steel at this time, it will all come out in the future when the future addition is added;  there is a masonry wall here (indicating).  Mr. Benard asked how long it will be before they get another building.  Mr. Wallmann said they have the property now, they expect an appropriation from the next legislature.

    The members unanimously agreed to approve Item 2.

    Item 3 - temporary penthouse - was discussed.  Mr Wallmann indicated the location of the penthouse;  he stated the building is designed for 3 more stories;  they wish to put sheet steel on the outside and plaster the inside;  it will be used partially as a plenum.

    The members unanimously agreed to approve Item 3.

    Item 4 - fire tower - was discussed.  Chief Gilman stated they have worked out something that he considers acceptable; he would like to say this may not apply in future cases so far as his opinion is concerned; it is strictly a modified smoke tower, but in this school building he thinks it would serve the purpose very well.  Mr. Wallmann indicated louvers, ladders and standpipes.  Chief Gilman said, in addition, they plan on taking the smoke up there with mechanical fan which will go on when the alarm goes on; otherwise it will be off.  When they complete the other quarters of the building, they will have 4 of them; there will be no fire escapes.  He wants detail drawings on those landings.  Mr. Wallmann said he will show them.

    It was unanimously agreed to approve Item 4, Mr. Newberry stating if it is approved by the Fire Marshal, he has no objection.

    Item 5 - basement class rooms.  It was unanimously agreed to approve this item.

Mr. Pederson moved:

      That the appeal be granted as follows:

      Item 1 - bridge - approved as shown.

      Item 2 - temporary exit stair - approved as shown.

      Item 3 - temporary penthouse - approved as shown.

      Item 4 - fire tower - approved as shown, subject to approval of Fire Marshal

      Item 5 - basement class rooms - approved as shown.

Mr. Bruun seconded the motion.  The motion was unanimously carried.

5. Appeal of 7-21-55

    Portland State College (old Lincoln H.S. Building).  This appeal involves deviations in the remodeling of auditorium and stage of building at 1620 SW Park.  The letter of appeal and check sheet read as follows:

    The letter of request reads as follows:

Letter of appeal - Portland State College (old Lincoln H.S. Building) - 1620 S.W. Park
--------------------------------------------------

    As architects for the referenced project, we are presenting this appeal on behalf of the Oregon State Board of Higher Education.  On January 18, 1955, the Fire Marshal's office transmitted a letter to the Administrative Assistant of the College calling attention to specific items to be corrected prior to the College opening date in September.  The items to be corrected related mainly to the Auditorium and Stage.  Bids for the work were called on June 29, 1955.  The Fire Marshal and Electrical Division were notified that plans for the corrective work were on file with the Bureau of Buildings.

    However, the original structure does not comply with Building Code Section 7-4200 in some instances, and we seek relief from the following paragraphs:

    7-4236:  which requires a fire wall of a minimum thickness of 12", brick or concrete and to extend 4 feet above the Auditorium or stage roof.  The proscenium construction is structural steel encased in concrete and 6" thick tile walls.  The ceiling of the stage is the third floor of reinforced concrete.  The roof of the Auditorium ceiling is at the third floor level.

    7-4237:  This paragraph is in regard to openings in proscenium wall.  The plans call for one opening at each side of the Auditorium, which is a single acting door entering into a stair hall which is an exit to the main floor corridor.  Also at the balcony at each side of the proscenium is a single acting door to an enclosed stairway leading to the second floor corridor.

    7-4238:  This section requires an asbestos curtain.  The height above the proscenium does not permit a one-piece asbestos curtain as required by the code.  In accordance with the Fire Marshal's instructions we have provided a sprinkler system for the proscenium opening as well as for the stage ceiling, under stage balcony and the first and balcony floor stairways at each side of the stage.

    7-4242Ventilators over stage.  This requirement is impracticable since there is a floor above the stage ceiling.  The stage and Auditorium is used primarily for college assemblies, guest speakers, dramatic classes, the production of college plays, the teaching of dramatic students the operation of stage equipment and props; used by the College orchestra and choral units.  The intended use of the area is not as a major theatre.

    We believe the plan as submitted has improved the conditions of the building from the standpoint of health and safety to the occupants.  Your favorable consideration to the above request is appreciated on behalf of the Oregon State Board of Higher Education.

                                            (signed) Clarence H. Wick

                                   ****************************

Check Sheet, prepared by Mr. Clerc:

    Construction Class III, Fire Dist II, Occupied as a school.

    Plans for remodeling of the auditorium and stage in this building show the following violations of the Portland Building Code:

    1. A 6" thick tile wall is used as part of the proscenium wall and does not extend above the stage roof.  Sec 7-4236 requires that the proscenium wall be 12" minimum thickness and extend 4' above the stage or auditorium roof.

    2. The openings in the proscenium wall, other than the curtain opening, are shown as metal doors.  Sec 7-4237 requires that these openings be protected by an automatic self-closing fire door on each side.

    3. No asbestos stage curtain is shown as required by Sec 7-4238.

    4. No ventilators are shown over the stage.  Sec 7-4242 calls for one or more ventilators, near the center and above the highest part of the stage, of a combined sectional area equal to at least 10% of the floor area within the stage walls.

    This checking sheet covers only the above points.

                                   ****************************

    Plans were spread before the members.  Mr. Hilgers explained that Mr. Wick had to be out of town today; he is appearing for Mr. Wick.

    Chief Gilman:  I would like to leave this remark with the Board:  all they are trying to do is to conform with recommendations of Capt. Miles, and, in endeavoring to do so, they run into these code violations, which are largely impossible to remedy in that building.  They intend to sprinkler this entire area (indicating).

    Mr. Mason:  I presume ventilation could be provided by going through the rooms above but it would be rather rugged.

    Mr. Newberry asked if they have changed the proscenium arch.  Mr. Hilgers replied, no;  the main change was exit from the stage.

    Chief Gilman:  I intended to check our letter before I came; I do know they are taking steps to meet the requirements that I asked.  The old wiring was in terrible condition; they had improvised stage lighting on the balcony on each side, the stage in general was in a poor state of repair, and the use wasn't good; they are changing that in respect to storage of costumes - it certainly would make it much more desirable than it was.  I don't see how they can meet these other requirements, (indicating check sheet).

    Mr. Newberry said it is impractical to do these things - so long as they sprinkler this area and put in new wiring.

    Mr. Mason:  In view of the comments of the Fire Marshal, I move

        That the appeal be granted
Mr. Foster seconded the motion.  The motion was unanimously carried.
 

6. Appeal of 4-14-66

    Portland State College.  This appeal involves alterations to an existing college building at 1620 S.W. Park Avenue.  The appeal reads as follows:

    Fire District 2, Zone AD & A0D, Type I, 4 story.

1. BUILDING CODE SECTION:  7-104 (d);  7-3304 (g)

    BUILDING CODE REQUIREMENTS:

    Alterations to any portion of an existing building, stairs and exits shall comply with the requirements for a new building.  Doors and frame opening into corridors shall be not less than 45 minute fire resistive rating.  Openings shall not exceed 25% of the area of the room wall adjacent to the corridor.
    PROPOSED DESIGN SHOWS:
    Existing corridor now connected to a complete loop with four existing exits total 2 at grade north side of building; 2 up one story south side of building.  We have provided 2 new exits up one-half story to grade west side of building.
    DEVIATION FROM BUILDING CODE REQUIREMENT:
    To leave the existing doors, frames and relites in place in the north, south and east corridors and no construction change with the stairs and exits from these areas.
    REASON FOR REQUESTED DEVIATION:
    The policy of P.S.C. is to upgrade existing doors and frames to code requirements as they perform alteration work in the building.  The building is being remodeled as money becomes available.  This remodeling work improves existing provisions.  In view of the above information, we ask that our appeal be granted.

          (signed) William R. Yost, Cambell, Miller, Michael
          Floyd Fuller, Bureau of Buildings

    The appellant pointed out that the new occupancy to be housed in the existing gymnasium space is to be adequately provided with exits.  The general feeling was that the exits throughout the entire building should be upgraded but that in connection with this project only the corridor doors immediately serving the new occupancy is brought up to code.
    Following the discussion recorded on Disc No. 041466-B, Mr. Foster moved:
     
      That the corridor and exit system on the floor in question be required to be brought up to code.
The motion was unanimously carried.  The $10.00 fee was turned over to the City Treasurer, Receipt No. 7748.
 

7. Appeal of 5-19-66 

    Portland State College.  This appeal involves alterations to an existing building at 1620 S.W. Park Avenue.  The appeal reads as follows:

    Fire District 2, Zone AD & A0D, Type I, 4 story.

1. BUILDING CODE SECTION:   *7-104 (d);  7-3304 (g)

    BUILDING CODE REQUIREMENT:

    Alterations to any portion of an existing building, stairs and exits shall comply with the requirements for a new building.  Doors and frame opening into corridors shall be not less than 45 minute fire resistive rating.  Openings shall not exceed 25% of the area of the room wall adjacent to the corridor.
    PROPOSED DESIGN SHOWS:
    Existing corridor now connected to a complete loop with four existing exits total 2 at grade north side of building; 2 up one story south side of building.  We have provided 2 new exits up one-half story to grade west side of building.
    DEVIATION FROM BUILDING CODE REQUIREMENT:
    To leave the existing doors, frames and relites in place in the north, south and east corridors for a maximum period of 12 months, during which time they would be modified or replaced to meet the building code.
    REASON FOR REQUESTED DEVIATION:
    This space is scheduled for remodeling and in some cases reclassification of the use of the space.  It would be economically wasteful to replace doors and frames that may have to be relocated or eliminated within less than a year.

            (signed) Richard Burling, Cambell, Miller, Michael
            Floyd Fuller, Bureau of Buildings

      * NOTE:  4-14-66 Building Board of Appeal:  Corridors and exit system on the floor in question be brought up to code.
    Following the discussion recorded on Disc No. 051966-B, Mr. Barbeau moved:
     
      That the appeal be granted on condition that the ruling of the previous appeal be carried out within 1 year (by June 1, 1967).

[Addendum Letter to the Building Code Board of Appeal:]

April 9, 1974

Bureau of Building
City Hall

Portland, Oregon 97204

Subject:    Portland State University
                Lincoln Hall - Fire Curtain

Portland State University plans to rehabilitate the Lincoln Hall Auditorium.  The project will remove the present balcony and provide one floor of seating.  The capacity will be reduced from about 750 to about 500 seats.  The stage house depth and height will be increased.  The entire stage house will be equipped for fire sprinkler protection and for smoke venting.

During its sixty years of use and auditorium stage has not had a proscenium curtain.  Since the UBC Code Section 708 stipulates a fire curtain at the proscenium opening, consideration of a fire curtain is encountered on account of the alteration project.  The proscenium opening is 30 ft. wide x 20 ft. high.

Portland State requests permission to eliminate the installation of the proscenium fire curtain for the following reasons:

    1) Sprinklered stage:  The entire stage will be protected by an automatic fire sprinkler system which could be extended to cover the area immediately in front of the proscenium as well as provide a water curtain at the proscenium.

    2) Smoke venting:  Three smoke release hatches will be provided over the stage to open automatically if there is a fire on the stage.  These hatches will keep most smoke and products of combustion directed away from the auditorium.  They can be activated by smoke detectors in place of fusible links.

    3) Forestage problem:  The theater arts department often uses stage sets that thrust out thru the proscenium to make a fire curtain unworkable or stage sets difficult to build with curtain slots.

    4) Cost saving:  The curtain is expected to cost about $12,000.  Since the budget is being rapidly depreciated by inflation, savings are essential to make the alteration possible.  Installing a fire curtain that might not function would be a serious waste of public funds.

    5) Exit Facilities:  With a smaller seating capacity the exit doors are improved with twelve doors directly accessible from the seating compared to the six pairs of doors that are somewhat remote from the audience.

The University makes this request with the understanding that the Fire Bureau is willing to consider alternatives to the costly fire curtain system provided by the Code.  Since the stage house is well protected by sprinkler and smoke venting we believe that the use of supplementary sprinkler heads at the proscenium will provide more effective protection than the curtain.

         1600 S.W. Park Ave.

1. BUILDING CODE SECTION:   3308 (c)

    BUILDING REGULATION REQUIREMENT:

    Openings into exit enclosures.  All exit doors in an exit enclosure shall be protected by a fire assembly having a fire protection rating of not less than one and one-half hours where two-hour shaft construction is required.
    PROPOSED DESIGN SHOWS:
    Non-rated assemblies exist at openings to stair towers (original doors and transom lights).  Under this contract sprinklers will be installed to protect each side of openings and audible fire alarm system with pull stations provided at each floor and each stair tower.
    REASON FOR ALTERNATE PROPOSAL:
    After discussion with the Fire Marshal, it was agreed that the proposed design was the best solution to meet the safety requirements for this existing building.  See correspondence attached.
