FACILITY CONDITIONS BUILDING ENVELOPE IMPROVEMENTS Install Through-Wall Fashing at Steel Lintels, Structural Steel Lintels Should be Thoroughly Cleaned of Corrosion and Painted with Quality Steel Coating, Repair or Replace Lintels that Show Major Damage. Replace Perimeter Sealant, Control Joints, Cast Stone Sill Joints at the Building Façade Taylors Falls Elementary School is a single-story building constructed of mass brick masonry walls and corrugated metal panels. The windows and doors throughout the complex are aluminum-framed with insulated glass glazing. In general, the brick masonry façade appeared to be in fair condition for its age.

Through-wall flashing is present along the sills of the windows. Steel lintels and weep vents were present at doors and windows heads. There is no metal drip edge or through-wall flashing installed along the heads of the windows and doors. Some through-wall flashing was present at the eastern portion of the building with a drip edge exposed. The original building section windows do not appear to have through-wall flashing present at the lintels above window/door openings in the brick masonry.

Many steel lintels at the building were in fair to poor condition. Some lintels exhibited corrosion and expansive forces into the brick. Layers of pack rust have also formed. Structural steel lintels should be thoroughly cleaned of corrosion and painted with a quality exterior steel coating. If major section loss is present, then repair of the lintel or replacement may be warranted. 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. Install through-wall flashing at existing steel lintels.

MECHANICAL AND PLUMBING Replace Eight (8) Rooftop and Inline Exhaust Fans, Replace Exhaust and Add Transfer Air to Lower-Level Locker Room, and Re-Route Water Heater Venting for Removal of Chimney, Add Demand Recirculation Pumps for Eight (8) Sinks with Hot Water Issues There are several rooftop and inline exhaust fans serving the building that have exceeded their recommended service life and are in need of replacement.

Nexus recommends replacing some of these fans when major work is taking place so the best pricing can be obtained from the contractors. Nexus has budgeted for the replacement of eight (8) existing exhaust fans for the school.

Nexus will work along with the district on the priority of which ones want to be replaced.

Nexus also recommends adding two (2) demand domestic hot water recirculation pumps for the classroom sinks that have trouble getting hot water in an appropriate amount of time. There are eight (8) classrooms with current hot water issues. These classrooms include rooms 109, 108, Quiet Room, Staff Restroom, 110, 111, 106, and 118.

Nexus also recommends replacing the inline exhaust fan serving the lowerlevel locker room and adding transfer air to better ventilate the space.

Fans will be a direct replacement to the original size/capacity but will have premium efficiency motors installed to increase energy savings. The fan size/capacity may be reduced if engineering can justify where over ventilation is occurring.

The existing water heating venting is routed right up through the chimney. As part of this improvement, we would reroute that venting so the chimney can be removed.

TAYLORS FALLS ELEMENTARY

FACILITY CONDITIONS MECHANICAL AND PLUMBING Replace Galvanized Plumbing Some domestic water piping located in the 1951, 1962, and 1970 portions of the building is old, galvanized steel. Over time, galvanized pipes are susceptible to corrosion and rust, which can lead to a buildup of mineral deposits within the piping. This corrosion process not only reduces water flow but also compromises water quality, potentially introducing harmful contaminants into the water used by students and staff. The deterioration of these pipes can lead to frequent leaks and occasional bursts, disrupting school operations and requiring costly repairs and maintenance.

Nexus recommends the replacement of the galvanized domestic water piping with insulated copper piping. Copper plumbing offers superior durability and resistance to corrosion compared to galvanized steel and does not suffer from the same accumulation of mineral deposits that can impede water flow and quality. Furthermore, copper pipes are less prone to leaks and bursts, ensuring a more reliable water supply. Importantly, copper systems do not carry the risk of leaching harmful substances like lead, providing a safer environment for students and staff and aligning with health and safety standards in educational facilities.

Benefits of this work would be reduced maintenance, improved water quality, and improved domestic hot water system.

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, energy-efficient 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 retro-commissioning 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.

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.

FACILITY CONDITIONS SITE IMPROVEMENTS Replace Pavement Around the North and West Side of the Building and Replace Part of the South Side Drive. Includes Restriping and Fence Relocation. Crack Seal and Sealcoat the Hard Surface Play Area and the South East Parking Lot. The West bus loop and parking was observed with significant cracking and in need of removal and replacement within the next few years. Previous borings should be analyzed, and possible new borings should be taken.

Cracked and chipped curbs and sidewalks were observed. Access to doors should be analyzed to update curb style as needed to provide ADA access to all doors as required. North door on the west side may need change to conform to requirements.

Pavement south of building and south parking needs typical pavement maintenance of crack seals and seal coats over the next few years. Reclaim and repave or a removal and replacement should be years down the line. Spot removal and replacement of cracked and failing curbs and gutter and walks is needed within the next few years.

FACILITY CONDITIONS SITE IMPROVEMENTS Purchase adjacent property and add new north parking lot with 20 additional spaces To improve parking on the west side of the school, the District could purchase the adjacent property. This would allow for a new north parking lot with an additional 20 spaces.

Extend south drive to Center Street to improve parent drop-off/pick-up Vehicles have backed up along West street during times of student drop-off and pick-up. Some of this has been resolved using the parent online app. To further resolve this problem the District can add a drive off the southeast parking lot that would exit onto Center street.

Replace aging playground equipment with new equipment, new plastic border timbers and engineered wood fiber. Existing swings and climbing tower to remain.

Some of the playground equipment is showing signs of deterioration and wear and should be replaced. The coatings have degraded over time, and in some cases, rust is starting to form. On some of the climbing apparatus there are exposed bolts, causing safety issues. The existing swings and one of the climbing structures would remain. The new equipment would be a mix of age appropriate items.

EDUCATIONAL ADEQUACY

EDUCATIONAL ADEQUACY Renovate & Expand Kitchen, Café, Receiving The kitchen is undersized for the number of students they are serving and has equipment deficiencies due to lack of space. They currently serve 240 breakfasts and 275 lunches on average. They currently serve food to students through a small window opening near the entrance of the cafeteria where lines back up into the hallway causing congestion. Currently, the receiving process for the building is done by unloading a truck next to an exterior door of the cafeteria and using hand trucks to bring food and deliveries into the building through the cafeteria. Depending on the timing of the delivery, this can be disruptive to before/after school activities as well as school-day uses in the cafeteria. The garbage cans also are taken through the kitchen in order to access the door to the dumpsters. An addition would be provided to expand and better the workflow for food service activities. It would provide space for equipment and processes needed for today’s food service requirements and create a dedicated servery for serving meals to students. The addition would provide dedicated receiving and building-wide storage that has immediate access to the exterior for deliveries and interior hallways to disperse the products. Renovations would also include relocating the food storage and coolers from the cafeteria to be in the food service space and allow internal expansion of the cafeteria.

EDUCATIONAL ADEQUACY

Renovate 3rd Grade Area Restrooms The existing toilet rooms near the 3rd grade classrooms are of original construction and the fixtures and finishes are beyond their useful life. In addition, the toilets an d sinks do not meet ADA and lack any type of supervision. These restroom areas would be renovated to still meet the toilet counts required by code and provide for increased supervision similar to the toilet renovations completed in recent projects at this building.

Add Resilient Flooring, Casework, and Shelving in Storage Rooms for Art. Music and Art are not instructed year-round and currently share a space.

That teaching space should be renovated to support multi-purpose functions, similar to recent renovations at Primary School. The room is large enough to create a space on the east end better appointed for art including hard surface flooring, providing casework for art storage, shelving solutions for adjacent storage rooms, and replacing the sinks to meet ADA requirements. There also exists a pair of double doors from the music area into the adjacent storage area. These doors are not used and could be eliminated to create more wall space for music.

EDUCATIONAL ADEQUACY Reconfigure Boiler Room Stairwell and Nurses Area The existing toilet room that serves the Nurse’s room is barely 30” wide and is vastly undersized. It is inadequate to serve students and their needs while seeing the Nurse. To create an appropriately sized toilet room that meets ADA as well as changing area for students in this age group, the impact would impede on the Nurse’s area.

The existing stair access to the basement boiler room would be relocated and this area would then be converted into a toilet/changing room. The nurse’s room would have updated finishes and casework to support the health services provided.

Add Metal Awning to South Gym Doors for Pickup/Dropoff At the end of the day, students that are receiving a ride by a parent/family member/guardian are queued in the Gymnasium. Staff escorts students outside when their ride approaches the pick-up zone, and staff supervises the traffic. The awning would provide for protection from weather for the staff and students, as well as help identify the zone for student pick-up.

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
