FACILITY CONDITIONS BUILDING ENVELOPE IMPROVEMENTS Replace Roof on 1999 1st Grade Addition and Multipurpose Room Addition.

Replace 1999 and 2001 Built Up Roofs Serving Office Area, Kitchen, and PreK Wing.

The roofs on the 1999 addition to the 1st grade classrooms and the multipurpose/cafeteria room (areas A, H and J) are reaching the end of their useful life and are showing signs of aging such as bridging / stretching at roof perimeters and multiple previous repairs. These roofs should be replaced in the next 3 years.

The roof over the pre-K classrooms, kitchen and boiler room (areas L, O and P) are also reaching the end of their useful life and should be replaced in the next 3 to 5 years. The pre-K classroom wing has a 2001 built up roof, while the kitchen, boiler room and front office are built up roofs done in 1999. The pre-K wing has a solar array that will need to be removed and reinstalled.

Roofing system replacement will improve energy performance by increasing system insulation values, reduce leaks, and will reduce operating and maintenance expenses.

FACILITY CONDITIONS BUILDING ENVELOPE IMPROVEMENTS Install Through-Wall flashing at Steel Lintels, Remove Corrosion From Structural Steel Lintels and Coat with Corrosion Inhibiting Paint, Install Sheet Metal Fashing with Drip Edge Where Necessary Within the Next 3 Years Through-wall flashing was not originally present at window, door, and other openings. However, drip edge flashing appeared to have been added at a few locations. Exposed steel lintels at many locations are forming pack rust. Through-wall flashings are not present on these lintels.

Lintels over and adjacent to window openings in brick cladding are corroded. Pack rust formation can apply pressure on the brick cladding and cause deterioration of the cladding. Corrosion also results in the loss of section of the steel lintels, which reduces strength and stiffness of the steel lintels. This condition warrants repair to prevent further damage to embedded steel and brick cladding, and to prevent water entry into and through the exterior walls.

The exposed steel should be cleaned, corrosion removed and coated with a corrosion inhibiting paint to minimize future corrosion/ deterioration. Install through-wall flashing at existing steel lintels. Install sheet metal flashing with drip edge where necessary.

FACILITY CONDITIONS BUILDING ENVELOPE IMPROVEMENTS Repoint Mortar Joints and Replace Cracked/Spalled Brick, Repair Bricks at Steel Bolts and Anchors In general, the brick masonry façade appears to be in good condition for its age.

Cracked mortar joints between the brick units were noted at several locations and vertical cracking was observed in isolated areas.

Cracked, spalled, and broken bricks were also observed. Localized mortar deterioration and isolated brick cracking/spalling is present.

These conditions are generally attributable to long term exposure to the elements. Vertical cracks located at corners are likely attributable to a lack of control joints on the façade. Step cracking in the brick facade is likely due to differential settlement.

Mortar is missing at one corner of brick full height. The joint with missing mortar full-height was likely cut for an expansion joint, but no sealant was installed.

General maintenance of brick cladding, including tuckpointing and replacement of damaged brick, is not needed at this time. However, a brick maintenance project to repoint deteriorated mortar joints and replace cracked/spalled brick should be planned in approximately 4 to 6 years.

Page | 299

PRIMARY SCHOOL

FACILITY CONDITIONS Steel rods and plates are protruding from the façade at a few locations. The brick surrounding these rods and plates has rust stains and the brick has spalled. The unfinished steel rod and plate corroded due to being exposed to the elements. Although some brick may have broken during the original installation, the majority of the brick damage at lintels is due to moisture intrusion/condensation through the bolt penetrations and the freeze/thaw cycle cracking and spalling the brick.

The purpose of this steel should be investigated further to determine whether they can be removed or if they require protection while repairing the adjacent brick. If abandoned, remove and repair brick masonry. If in use, determine if thermal transfer is occurring and eliminate thermal transfer during the brick repairs.

BUILDING ENVELOPE IMPROVEMENTS PS-BE-4 Repoint Mortar Joints and Replace Cracked/Spalled Brick, Repair Bricks at Steel Bolts and Anchors • Replace brick (approximately 400) • Repoint 2500 square feet • Investigate the steel rod and plate to determine if needed • If abandoned, remove and repair brick • If in use, eliminate thermal transfer during brick repair PS-BE-4 Benefits • •

PRIMARY SCHOOL

FACILITY CONDITIONS BUILDING ENVELOPE IMPROVEMENTS Replace Sealant at Doors, Windows, and Control Joints Exterior sealant at windows, doors, corners, and other areas of the façade is in poor condition. Weathering, splitting, debonding, and cracking of sealant was observed throughout the façade.

Exterior sealants deteriorate as a result of exposure to UV light, moisture, and temperature cycles. Sealants typically have a lifespan of 8-12 years depending on material, material quality, and application/configuration.

Based on observed conditions, it appears that the sealants on the building have reached or exceeded their useful life.

Sealants are an important component of the exterior building envelope and in many cases are the first line of defense in preventing water entry into and through exterior walls. Deteriorated sealants greatly increase the potential for water entry.

Replace all window and door perimeter, control joint, and penetration sealant at the building façade, as well as any miscellaneous sealants present. These repairs should be completed in the next 0-3 years.

PRIMARY SCHOOL

FACILITY CONDITIONS MECHANICAL AND PLUMBING Add Dehumidification and Powered Relief to Gym Air Handling Unit The Primary School Gym is currently being served by a 2021 air handling unit (AHU) with hot water heating but no means of dehumidification.

The lack of dehumidification results in higher humidity levels and occupant discomfort in the gym. The gym is also unable to meet the American Society of Heating and Refrigeration Engineer’s (ASHRAE) Thermal Environmental Conditions for Human Occupancy Standard 55. This ASHRAE design standard specifies the combinations of personal and indoor thermal environmental requirements necessary to achieve an occupant comfort satisfaction rate of 80% or greater. These indoor environmental requirements include temperature, thermal radiation, humidity, and air speed.

Nexus recommends adding a new DX dehumidification coil to the air handling unit to allow for dehumidification of the code required ventilation air to the gym. The coil would be mated with a new air-cooled condensing unit (ACCU) and refrigerant piping would be extended to the air handling unit as required.

Nexus also recommends adding powered relief to the gym in lieu of gravity relief. Powered relief systems provide enhanced control, efficiency, and adaptability compared to traditional gravity relief systems, contributing to better overall performance and operational benefits in air handling units.

The benefits of these upgrades include improved equipment scheduling, improved ventilation, increased energy savings, improved occupant comfort, and an improved learning and working environment.

FACILITY CONDITIONS MECHANICAL AND PLUMBING Replace 2005 R-22 ACCU Serving Multi-Purpose Room and Associated Coils and Add Ventilation to Maintenance Office The existing 2005 condensing unit serving the multi-purpose air handling unit is starting to corrode and deteriorate. This 20-year-old condensing unit is still utilizing R-22 refrigerant which has become obsolete and far less efficient than today’s systems.

Nexus recommends replacing this old inefficient air-cooled condensing unit and the mated DX dehumidification coil with a new air-cooled condensing unit and associated DX dehumidification coil with American Society of Heating and Refrigeration Engineer’s (ASHRAE) code compliant refrigerant that is more energy efficient and environmentally friendly. New refrigerant piping would be installed as required for the new refrigerant.

The Maintenance Office 125 currently has no ventilation, which does not meet the current code for ASHRAE 62.1 Ventilation for Acceptable Indoor Air Quality. This code provides the minimum outside air ventilation rates that are required in the breathing zone for specific spaces.

Nexus recommends adding ventilation to the maintenance office from an adjacent air handling unit to bring in the code required ventilation air.

FACILITY CONDITIONS MECHANICAL AND PLUMBING Retro-Commissioning of HVAC Equipment Building retro-commissioning is a systematic process that ensures all buildings perform as efficiently as possible according to the owner’s operational needs as well as adjustment of HVAC equipment’s operational parameters to meet current space use.

The Building Automation System (BAS) plays a crucial role in providing a comfortable, energyefficient environment for students, parents, and staff. Over time, damper and valve controls have gone out of proper adjustment, components fail, and controls sequences are modified and may not be programmed to provide an optimal balance between comfort, indoor air quality, and energy efficiency.

This Nexus Retro-commissioning Team will identify the root cause of HVAC equipment operational issues and will provide adjustments to the sequences and outdoor air setting to improve occupant comfort while reducing energy consumption where possible. The retrocommissioning process will also identify components that require adjustment or replacement.

Retro-commissioning activities include: HVAC Equipment: Nexus will verify existing HVAC equipment operation and control sequences through observation. We will provide adjustment and tuning services to achieve optimal operation and improved occupant comfort. Documentation of the findings with corrections and recommendations for further improvements will be made.

Services include: • Ventilation study to assure all spaces are ventilated per the current code requirements and the outdoor air setpoints will be adjusted up or down based on current space occupancy • Test point commands vs actual controller output at each device for heating, cooling, and mixed air control • Verify valve/damper operation on reheat coils and air handler coils • Verify indicated vs actual (duct static, supply and return temperatures) • Verify mixed-air operation (damper position and economizer operation)

Page | 320

PRIMARY SCHOOL

FACILITY CONDITIONS Valves and Dampers: Nexus will test all existing rooftop (RTU) and indoor air handling unit (AHU) sequences along with the valve and damper operation to ensure control actuators are fully operational. We observe valve/damper/actuator operation and check for any physical signs of valve/damper leakage or binding, which results in operational issues and increased energy consumption. We check discharge temperature with valves in the fully open and closed positions. In addition, we will provide unit pricing to replace any defective valves and/or actuators. Proper RTU and AHU operation provides improved occupant comfort at optimal energy efficiency.

Zone Reheat Valves: Nexus will test existing zone reheat valves for proper operation. We ensure command valves fully open and close and observe valve/actuator operation. We inspect valves for any physical signs of valve leakage or binding, check discharge temperature with valve in the fully open and closed positions and provide unit pricing to replace any defective valves and/or actuators.

Economizer: Nexus will update the control sequence for mixed-air dampers to their setpoints with economizer lockout setpoints.

Heating Water Pump Variable Speed Drives (VSDs): Nexus will lower the pressure setpoint to allow drives to modulate down to the slowest speed required to satisfy the most critical room temperature sensor.

Boilers: Nexus will optimize sequencing and staging of equipment and adjust the water reset schedules based on outside air temperature.

The action steps noted above are part of the Nexus retro-commissioning process. The benefits of this process include improved temperature control and occupant comfort, reduced energy consumption, reduced maintenance, and extended HVAC equipment life.

FACILITY CONDITIONS ELECTRICAL, TECHNOLOGY AND SAFETY SYSTEMS LED Lighting Upgrade for Areas with Fluorescent. Retrofit Kits for Fixtures in Good Condition, Replacement for Unique or Outdated Fixtures. Includes 3 Exterior Lights and 54 Emergency Lights The existing lighting in classrooms, gymnasiums, and common areas is primarily fluorescent lamps throughout. The fixtures appear to be in fair condition; however, LED lamp technology is more energy efficient.

Replacing the light fixtures with LED light fixtures will reduce energy use and maintenance costs. LED light fixtures have a life span of more than 50,000 hours and do not require lamp replacements, which reduces maintenance costs.

It is recommended that the lighting controls be upgraded to include dimming and occupancy sensors.

There is an area outside that is frequently used that is not well lit. It is recommended to add light fixtures as necessary in this area to provide adequate light, which will enhance the safety and security of students and staff.

In addition, emergency batter lights have a useful life of 10-years. It is recommended that emergency lights be replaced to reduce maintenance costs due to fixture or battery replacement. Note – the costs were included in the lighting costs for 54 emergency lights. If the generator is accepted, the cost for these lights would be used to route emergency power throughout to lights so they can be on the generator per our discussion with Kyle.

FACILITY CONDITIONS SITE IMPROVEMENTS Remove and Replace Pavement of the Hard Playground on East & West Sides of Building. Improve Drainage with New Catch Basin.

During the site visit it was observed that the asphalt on the east and west hard play areas had a lot of cracking with signs of previous crack sealing. The east hard play area does not drain properly causing safety issues including ice formation. Both the east and west hard play surfaces need to be removed and replaced with new asphalt. A new catch basin should be added to improve drainage of the east area.

PRIMARY SCHOOL

FACILITY CONDITIONS SITE IMPROVEMENTS Remove and Repair North Loop Driveway, Parking Lot, and South Parking The North parking lot aesthetically is poor because of numerous patches during previous projects, but the pavement is also starting to fail. Lot could benefit from regrading to improve drainage. With storm sewer possibly extended over to the east play area it may now be possible to extend it further to the north parking and add catch basin(s). The south parking lot and drive also had a few areas where pavement was failing. Some areas of curb and sidewalk throughout the site have cracks and large chips.

SITE IMPROVEMENTS PS-SI-4 North loop driveway and parking lot • Remove and replace asphalt • Concrete pavement spot replacements • Curb and gutter spot replacements • Minimal fine grading/ soil correction PS-SI-5 South parking lot • Remove and replace asphalt pavement • Concrete pavement spot replacements • Curb and gutter spot replacements • Fine grading/soil correction PS-SI-4 & 5 Benefits • • •

Increased safety Decreased maintenance issues Improves facility aesthetics

PRIMARY SCHOOL

FACILITY CONDITIONS SITE IMPROVEMENTS East and West Playground Equipment, new curbing and top dress wood chips The majority of the playground equipment has reached the end of its useful life and should be replaced. The existing arch and tire swings and unity climber on the east playground should remain as they still have some life. On the West playground some of the existing structure, the tire swing and the spin cup should remain. The plastic curbing should be replaced with new concrete curbing.

The wood chips should be top dressed, so it is at the designated height for safety. The new equipment would be age appropriate.

PRIMARY SCHOOL

FACILITY CONDITIONS SITE IMPROVEMENTS Softball / Kickball Field Improvements While onsite it was observed that the east backstop is leaning and should be removed and replaced. Additional fencing to fill gaps to stop balls would make the field more user friendly. The outfield fence is heaving and shifting but still appears to function as an outfield marker that stops balls.

All fields could benefit from weed killing and a top dressing of aglime.

Wetlands exist between the north and south fields so no drastic changes can occur without looking at old surveys and possibly requesting a new survey and wetland delineation.

SITE IMPROVEMENTS • PS-SI-9 Repair and upgrade two softball fields with new fence and backstops • • • • •

Remove east backstop as it appears to not be stable Install new backstop and additional sideline fencing Top dress aglime Improve field with installation of benches Budget for future removal and replacement of outfield fence PS-SI-9 Benefits •

EDUCATIONAL ADEQUACY

EDUCATIONAL ADEQUACY RECONFIGURE KITCHEN & RELOCATE SERVERY The kitchen is undersized for the number of students they are serving and creating lines for serving students in a hallway is not ideal. The current average daily participation is 150 breakfast and 290 lunches over 9 lunch periods. Renovations allow expanding of the kitchen by relocating the receiving area to be more centralized within the building and creating a formalized serving area with adjacency into the cafeteria. The new formalized serving area would provide space to utilize equipment that will maintain the proper food temperature during meal service.

DEMOLISH STAGE. RELOCATE RECEIVING AND TSA, PSYCH, PE, AND SPEECH OFFICES. CREATE CHAIR STORAGE ROOM OFF THE GYMNASIUM AND RELOCATE DOUBLE DOORS. The Primary School was not designed to provide the student services that schools are now required to provide. The school has needs for officing (shared or dedicated) various support team members such as Psychologist, Speech, TSA, as well as providing the “stop and think”, which all support District initiatives. Providing dedicated space for these programs allows the student to engage with the staff or service with dignity. The existing stage space is underutilized as it is being used for storage. The stage would be converted to create these small rooms for officing and student services. A chair storage room would be created on the south end of the gymnasium.

EDUCATIONAL ADEQUACY

MEDIA CENTER RENOVATION Media Centers have evolved over the years and have become a place for many resources beyond just books and research. The desire is to renovate the space to increase flexibility to best serve the versatile needs of media center and large group work.

DIVIDE READING ROOM INTO THREE SEPARATE TEACHING SPACES FOR ACOUSTICAL SEPARATION Reading Intervention is provided with one staff member and a small group of 4-5 students. The scope includes formalizing the current situation of cubicle partitions into walls and doors with teaching surfaces (marker- and tack- boards) to provide acoustical privacy to allow student focus and enhance hearing/audible connections. Three small group rooms would be created in the current reading intervention space. These group rooms could support other small group activities outside of reading intervention.

The space would provide flexibility for the building because it currently lacks small group instructional areas.

INSTALL PERMANENT SHEETROCK WALLS IN KINDERGARTEN AREA In the Kindergarten classrooms, the walls separating the spaces, and the hallway are demountable wall assemblies. These walls are well past their useful lives. To enhance acoustical separation and increase durability, these demountable walls were requested to be replaced with permanent walls constructed to the underside of the roof. This would require replacement of the casework and teaching surfaces (marker- and tack- boards) that are currently located on the demountable walls.

NEW FLEXIBLE CLASSROOM FURNITURE (50%) Most classrooms have outdated furniture or do not have sufficient flexible furniture available that will attract students to those areas.

Comfortable and inviting furniture has been studied to be as important to the spaces as the lighting, HVAC, and spaces themselves.
