1. ARCHITECTURAL

1.1 Overview

The East building is a 4-story B occupancy structure divided into various o=ices suites on levels 2-

4 with reception, covered parking, bike storage, a clinic and café on the ground level. The fourth floor also includes a kitchen/commons area with a balcony amenity overlooking the street to the south. A large atrium anchors the north and south wing across all three upper levels. Restrooms are on each level as well as exit stair shafts.

The West building is similarly arranged across five full floors plates of various o=ice and open o=ice plans however no atrium space. Smaller kitchenettes are dispersed throughout as well as a balcony space on the fourth level.

Both buildings have a similar mix of interior gypsum board and glazed wall partitions. Laminate, carpet, and polished concrete flooring can be found throughout, as well as each building having shower/locker room facilities on the ground floor.

Renovation for the East building is planned for all four floors while only levels one and two on the

West will be assumed to be for use by the GACEE program function. Levels three through five (of

West) are intended as leasable spaces not to be developed by PPS. Both building renovations are intended to be designed to meet LEED Silver Standards.

2. ENVELOPE NARRATIVE

2.1 Overview

The primary existing building façade is a rainscreen assembly predominantly of clear vertical wood siding with minimal use of metal panel and plaster board at select locations. Glazed aluminum store front and window systems provide interior daylight. The wood siding has been recently refinished and is in overall very good condition. There are instances of cracked and stained plaster visible from the ground level. Metal panel siding and exposed steel at street level appear in generally good condition with the exception for areas directly facing the covered parking of the east building. Damage from minor vehicle collisions appears at this location. Biological build-up and staining from minimal profile edge metal is observed where roof overhangs meet exterior plasterboard walls. Additional minor instances of damage include chipped exposed concrete pony walls at outside corners and minor instances of chipped paint on steel surfaces, primarily at window surrounds at the lower level.

2.2 Proposed Repairs & Alterations

• Replace or add edge metal at roof to wall drip edges with minimum ½” drip leaders to get roof runo= away from vertical plaster surfaces.

• Clean stained/biological build-up on vertical plaster surfaces.

• Repair plaster finishes on so=it and wall locations where cracking and separating appears.

• Provide sealant at window jamb locations where missing or damaged.

• Patch/repair concrete corners and/or provide heavy gauge steel corner protection covering damage.

• Develop routine insect cleaning schedule for window and alcove overhangs.

• Install exterior stainless steel corner guards at all outside corners of street level structure.

• Remove all abandoned business signage a=ixed to building - patch walls where necessary.

• Remove all vinyl signage on exterior glazing where no longer relevant to building use. (Address signage to remain)

• Add missing wood louver to gate in covered parking area (East BLD)

• Install protection cages on exterior fire sprinkler heads where permitted by code.

• Comments as noted in the 2025 Interface Engineering/Bassetti/KPFF Building Assessment Report as follows:

o Install and secure roof drain strainers where missing o Adjust sagging roof mechanical screen doors for operability concerns o Adjust solar panel racks to provide code-compliant walkways at roof perimeter.

o Engage with PPS Risk to evaluate roof terraces for student and public use areas. Review guardrails at roof ledges and access controls for after hours.

o Evaluate installation of additional fall arrest anchors for worker safety tie-o=s per PPS standards & OSHA requirements at roofs of both buildings. Installation of new stair enclosures at both buildings:

o Demolition and removal of existing windows and wall area approximately 120sf total at each building for stair enclosure connection.

o Installation of structural steel or laminated wood header, miscellaneous building envelope and flashing materials, and interior finishes (See architectural narrative to stair construction and enclosure).

o Install new rated glazed door/window assembly at building face to stair enclosure (see floor plan diagram).

• Paint exterior plaster apertures to establish new street presence and identity to the building.

3.1 Overview

The East and West buildings abut the pedestrian walkway on two sides and form an interior courtyard, bisected central alleyway, and terminate at a zero-lot line commercial building on the north side of the west building and a converted SFH property on the north of the east building. The central alley terminates with removable bollards at a church parking lot on the north. The central courtyard formed by the East and West buildings and alleyway is structured as a singular plaza surfaced with paver stones, and planted areas with ornamental grasses and trees with concrete seating units throughout.

3.2 Proposed Alterations

• Comments as noted in the 2025 Interface Engineering/Bassetti/KPFF Building Assessment Report as follows:

o Repair uneven courtyard paving system, particularly at paths along building entries/ exits.

o Evaluate bicycle parking for zoning compliance.

o Measure exit path illumination levels to ensure code compliance. Upgrade as needed.

o Install van-accessible parking signage and pavement markings per building code.

o Improve courtyard lighting levels for visibility during dusk to dawn hours.

o Review building code appeals for stair rail termination issues.

• Provide new parking entrance signage at northeast entry.

• Provide new site monument signage at south entry.

• See Architectural Narrative for description of new/proposed feature stair to level 2 of East and

West buildings.

• Renovate courtyard adjacent to East and West building for:

o Stair structures, i.e. foot excavation, trenching for power & fire water, reconstruction of paving & plantings.

o To increase usable hardscaping for event space.

Reduce planted areas, remove one tree.

o Eliminate step in landscape in lieu of ramping for wheelchair accessibility.

o Consider adding low physical barriers along central Alley to create a clear separation of auto and pedestrian opportunities in this plaza.

4. STRUCTURAL

4.1 Overview

The conversion of the existing buildings to the new Grice-Adair Center will be a Level 3 alteration and some small additions for stair connecting level 1 & 2. No change of the building occupancies are expected and the building-risk categories are anticipated to remain II. The alterations are not anticipated to alter the existing gravity or lateral force-resisting systems. Since the occupancy and risk category will remain the same, no lateral force-resisting system upgrades are anticipated. See

“Code Summary” section for additional information.

4.2 Proposed Alterations

The new stairs will be built inside a new addition outside of the existing footprint of the buildings.

The stair enclosure will be steel or glulam timber framed to match the existing structural systems with glazing to allow for visual supervision of circulation paths. Foundations for the new additions will be shallow conventional spread footings.

Per the existing building drawings and calculations, the floors were designed for 80 psf live load.

The conversion of the space for this new usage is not anticipated to exceed the live load the building was designed for.

Where new, heavy equipment is proposed, the existing floor decking and beams will be evaluated for the additional load. Localized reinforcement may be required to be strengthened. Existing column & foundations reinforcement is not anticipated.

4.3 Load Definitions

Building Risk Category:

o II (to match existing building design)

Floor Live Loads:

o All elevated floors 80 PSF (to match existing building design) o Stairs 100 PSF

5. FIRE PROTECTION, PLUMBING, MECHANICAL

5.1 Fire Protection

5.1.1 Overview

There is an existing fire sprinkler system routed throughout both buildings. The sprinkler system will need to be modified to accommodate the new layout.

5.2 Plumbing

5.2.1 Overview

The existing plumbing system consists of a natural gas fired water heater in each building with domestic cold water, domestic hot water and how water circulation piping routed to all the fixtures. It is assumed the water heaters are in good condition.

5.2.2 Proposed Alterations

The plumbing systems will need to be modified to serve any new fixtures added to the facility.

Additional hand sinks will be added into lab/art spaces and will need to be included with clay traps. The existing grease interceptor system will need to be confirmed to meet the new/current

City of Portland Code Plumbing Code requirements. If found to not meet current requirements, a new grease interceptor will need to be installed to accommodate any food service in the building.

Modifications and increased quantity of existing restroom layouts will move toward o=ering all gender/single user restrooms.

5.3 Mechanical/HVAC

5.3.1 Overview

There’s an existing DOAS (Dedicated Outside Air System) unit on the roof of each building. This

DOAS unit provides conditioned ventilation air to all spaces. There’s a VRF (Variable Refrigerant

Flow) system that provides temperature control in each space. The existing HVAC (Heating

Ventilating Air Conditioning) system is approximately 11 years old. The expected lifespan of a VRF system is approximately 15 -20 years.

5.3.2 Proposed Alterations

The school district has indicated that they want these systems to be designed to provide at least

15-20 years of service. In order to provide this life expectancy, it is recommended that the VRF system be replaced with a new system that is designed to align with the new layout of each of the spaces. It is assumed that the DOAS units are still in good condition and will continue to operate for the expected lifespan of the buildings. The ventilation ducts will need to be reconfigured to match the new layout on each floor and possibly add more DOAS units to accommodate the planned renovations. For CTE/LAB spaces there might be a need for additional exhaust or air filtration systems based on specific equipment proposed. It is assumed that any new air treatment system would be small and self-contained.

Lighting o All new luminaires and systems will be provided and selected to match the building’s aesthetic while also meeting e=iciency, durability, and ease of maintenance concerns.

o Lighting levels shall be in accordance with recommendations of the Illumination

Engineering Society (IES) and energy usage shall not exceed the requirements of the

Oregon Structural Specialty Code.

o Interior lighting shall be provided with medium quality specification grade LED type fixtures with dimming drivers for continuous dimming. Color temperature will be 3000K.

o Exit signs shall be high abuse vandal resistant, white color with green lettering. PPS design standard approved manufacturers “Lithonia Extreme” and “Kenall Trailmate 6500 high

Abuse” LED.

o Exterior lighting shall be replaced with LED type fixtures. Exterior lighting will meet dark sky initiatives through the use of full cuto= fixtures, thus reducing light pollution.

Lighting Controls o All lighting controls will be designed to meet the 2025 Oregon Energy E=iciency Specialty

Code (OEESC) as well as the requirements in the Portland Public Schools Design

Standards.

o Controls will consist of distributed devices networked together to form the system. It will include low voltage digital switches, occupancy/vacancy sensors, daylight sensors, plug load sensors, relay panels and networking devices. The basis of design will be open spec unless ownership defines a preference.

7.1 Proposed Alterations – Low-Volt Systems

7.1.1 Wireless Network Upgrades

The project shall include wireless network infrastructure upgrades to support current District standards and future operational requirements.

o Provide and install two CAT6A cables, including all associated pathways, and infrastructure, to support wireless access point (WAP) installations in the following spaces:

Classrooms

Music Rooms

Administrative and O=ice Areas

Kitchens and Cafeterias

Commons Areas (multiple locations as required to achieve adequate coverage)

Multipurpose Educational Spaces (multiple locations as required to achieve adequate coverage)

Auditoriums (multiple locations as required to achieve adequate coverage)

Active Learning and Recreational Spaces (multiple locations as required to achieve adequate coverage)

Computer Laboratories (multiple locations as required to achieve adequate coverage) o Wireless access points shall be ceiling-mounted where ceiling heights do not exceed 12 feet above finished floor (AFF).

o Where ceiling heights exceed 12 feet AFF, wireless access points shall be wall-mounted at

11 feet AFF.

o Each wireless access point location shall be terminated in the field at a two-port telecommunications outlet.

Note: Wireless access point mounting heights and locations are based on current District standards. Modifications to these standards may be considered where site-specific architectural conditions or unique spatial characteristics warrant an alternate installation approach.

7.1.2 Fiber Optic Backbone & Frame Rooms

o Remove and replace the existing multimode fiber optic backbone with the District standard armored, 12-strand single-mode fiber optic backbone throughout the campus.

o Equipment bonding within Frame Rooms shall be replaced to meet current District and

BICSI standards.

Note: Existing telecommunications infrastructure is manufactured by CommScope.

7.1.3 Horizontal Cabling

o Provide one Dual CAT6 Data outlet on each wall in a standard classroom.

o Provide Quad CAT6 Data outlet at each CTE/Maker Space workstation.

o Provide one CAT6 outlet in classrooms, music rooms, computer laboratories, and other

Owner-directed locations for District-standard wall phone installations. Outlets shall be located between 34 and 45 inches AFF and within 6 feet of the primary room entrance.

Note: Existing horizontal cable pathways are routed through floor boxes embedded throughout the concrete slab, which could be reutilized in support of CTE/Maker Space workstations if architectural design permits interception of existing pathways at the existing countertop IDFs.

Relocation of telecommunications pathways may require the use of surface-mounted raceway systems.

7.1.4 Special Systems

o Provide Dual CAT6A outlets in classrooms, music rooms, libraries, and other Owner-directed spaces to support instructional technology and projection systems.

Provide pathway infrastructure to support audiovisual (AV) systems.

Recommend existing large format AV system to remain in service if feasible, including, but not limited to, the Bose sound reinforcement system located in the East Building presentation space.

Provide paging and intercom systems, including associated cabling and infrastructure, as outlined in the current PPS design standard.

7.2 Electronic Safety and Security Systems

o Provide card reader-controlled access at designated building entry and interior security doors.

o Existing access control panels shall be removed and replaced to conform with District standard.

o New access control panels shall be installed in secure locations within existing Frame

Room.

o Existing pathways and access control devices shall be reused where feasible. For the purposes of estimating assume all existing raceways are not reusable.

o Provide new access control readers at each elevator landing to align with current

District standard.

o Provide one CAT6A cable including all associated pathways and infrastructure, to each security camera location.

o Security cameras shall be installed in common-use and circulation areas, including but not limited to:

Hallways

Stairwells

Commons Areas

Cafeterias

Building Entrances and Exits o Existing exterior camera pathways and mounting locations may be reused where feasible. For the purpose of estimating assume all pathways are not reuseable.

o Existing camera equipment and associated infrastructure shall be removed and replaced to conform to current District standard.

7.3 Proposed Alterations – Fire Alarm

o Remove and replace all existing Simplex fire alarm equipment and devices and replace with new District standard Potter fire alarm equipment and devices.

o Existing smoke curtain assemblies and related equipment and devices in the East

Building shall remain and be integrated into design.

o Existing Ansul suppression hood assemblies and related equipment and devices in the

East Building shall remain and be integrated into design.

Note: Fire alarm designs are based on verbal direction given in 07-20-2026 design coordination meeting, directing that the buildings are to remain a B Class Occupancy, Risk Category II and not an E Class Occupancy, Risk Category III as indicated in the feasibility and building assessment reports provided.
