1 HOLUM EDUCATION CENTER Architectural The existing building has approximately 41,823 square feet and sets on a lot about 4.14 acres in size. Parking lots are located along the east and west sides of the building. There are about 50 parking stalls along the west side of the building. Buses and parents currently drop students off along East Holum St. The building is mainly a load bearing masonry wall building with steel floor and roof structures. Some minor cracking was noted in the concrete block walls. These areas should be reviewed and inspected for possible repairs and to determine the reasons for the cracking. See photo 1. This work should be completed as a priority 2 renovation. The upper level of the building is occupied by the school district offices. See photo 3 Photo 3-School District Offices on upper level There are several interior doors that show signs of damage and should be replaced as a priority 2 renovation. See photo 4. Photo 1-There are signs of cracked concrete block and water damage at the north entry doors priority 2 The play equipment is currently located inside a fenced play area near East Holum St. It appears to be on an accessible route and we did not see any safety concerns at this time. See photo 2. Photo 4-Damaged Interior Doors There are a few areas where the ceiling tiles have been damaged either by water leaks or work above the ceiling. This appears to be minimal and does not require immediate attention. This work should be considered as priority 3 repair work. The VCT in the gymnasium has some damage and could be replaced as a priority 2 renovation See photo 4. The main corridor flooring appears to have been replaced within the past 5 years and it appears to be in great shape. See photo 5. Photo 2-Playground Equipment Existing Facilities Survey Page 23

2 There is damage to walls and base at the east entry to the receiving area, see photo 8. This should not be considered a required repair. Photo 5-There are several areas where the existing VCT is damaged and needs replaced priority 3 Photo 8-Damaged Wall and Base Existing wood bleachers do not currently meet egress requirements. See photo 9. Photo 6-Main Corridor Flooring The casework and counters in the OT/PT classroom do not meet the current ADA/ANSI requirements, see photo 7. This work should be done as a priority 1 renovation. Photo 9-Wood Bleachers The student toilet rooms do not meet current ADA-ANSI requirements and should be looked at for upgrades and renovations. The sinks appear to have been replaced within the last 5-10 years. This work should be considered as a priority 1 renovation. See photos 10 and 11. Photo 7-Casework and counter tops in the OT/TP classroom do not meet ADA accessibility requirements priority 1 renovation Page 24 Existing Facilities Survey

3 Photo 10-Toilet Rooms Photo 13-Weathering of Wood Windows The EIFS control joints need to be cleaned out and resealed. We noticed this in numerous locations. This work should be completed as a priority 2 repair. See photo 14. Photo 11-Toilet Rooms The building has a combination of wood and aluminum sliding & fixed windows. The wood windows should be replaced for energy conservation reasons. They are also showing signs of weathering and aging. See photos 12 & 13. This work should be considered as a priority 2 repair. Photo 14-EIFS Control Joints Cracked Open Several of the hollow metal doors and frames are damaged and are rusting. See photo 15. This work could be done as a priority 3 repair. The concrete stoops are showing some cracking and thermal sequencing damage. This repair work should be done as priority 3 repairs.

4 Photo 15-Rust on Exterior Hollow Metal Doors & Frames and Cracked Concrete Stoops The plywood soffit at the north entry has had several water leaks and the roof drain piping should be re-routed - priority 2. See photo 16. Heating, Ventilating and Air Conditioning Systems Heating: The boiler room located in the lower level mechanical room contains one steam boiler (forty-plus years old). The boiler provides steam heat to the building via unit ventilators in perimeter zones and steam heating coils in air handling units and rooftop units. Condensate pumps are located in the lower level mechanical room, which are the same vintage as the boiler. There are also steam unit heaters and cabinet heaters that provide heat to miscellaneous spaces throughout the building. Expected Useful Life (based on ASHRAE published data): Boilers: years Condensate Pumps: years Terminal Equipment: years Photo 16 North Entry Soffit Overall, the exterior of the building is in good shape and could be repaired and cleaned up with minimal work. Roofing: This building includes two different types of roofs which equate to eight different roof areas totaling 30,477 square feet (SF). 1. Tremco BURmastic 200 totaling 8,810 SF or 29% of the total roof, are in good condition. 2. Tremco POWER ply Supreme totaling 21,656 SF or 71% of the total roof, are in fair to poor condition and should be replaced. Safety and Security The existing building security appeared to function upon our arrival but could be reviewed for new upgrades to meet the school s current needs. Photo 17 Existing Boiler The boilers and associated components are at the end of their useful life and should be considered for replacement. A hot water boiler system would be a more cost effective and efficient system for this building application and size. If the steam boiler system is not replaced, we recommend the copper steam condensate return piping be replaced with steel and insulated to improve system efficiency. Cooling is provided in portions of the building through DX coils locate in indoor air handling units and rooftop units. The age of DX equipment was unknown at the time of assessment, but units appear to be twenty to thirty years of age and approaching the end of useful life. There are portions of the building that are not currently airconditioned. Expected Useful Life (based on ASHRAE published data): Rooftop units: years Indoor air handling units: years Page 26 Existing Facilities Survey

5 Provide air conditioning in spaces that are not currently conditioned. Four of the six roof top units were installed in 1988 and are nearing the end of their useful life. These units should be replaced in the near future. Ventilation to classrooms in the lower level is provided by unit ventilators, which are twenty-plus years old. Ventilation to office spaces on the first floor is provided through heating only air handling units. The exact age of the air-handling units is unknown, but they were installed prior to There are also six rooftop units that provide overhead air to spaces throughout the first floor. Four of the six roof top units were installed in 1988, and are at the end of their useful life. The two others were replaced in 2008 and 2013 and appear to be in good working condition. Expected Useful Life (based on ASHRAE published data): Rooftop units: years Indoor air handling units: years Unit ventilators: years The unit ventilators are approaching the end of their useful life and should be considered for replacement. The air-handling units installed prior to 2001 appear to be operating properly, however, are approaching the end of their useful life. Four of the six-rooftop units are at the end of their useful life, and should be replaced. The remaining two-rooftop units appear to be in good working condition. Plumbing System There is one gas fired water heater located in the lower level mechanical room. All hot water to the building is softened. Both the water heater and water softener were installed in 2005, and appear to be in good working condition and no problems reported by maintenance staff. Expected Useful Life (based on ASHRAE published data): Water Heater: years Water Softener: years Photo 18-Existing Water Heater & Water Softener Both the water heater and water softener are in good working condition and appear to adequately serve the needs of the building. Fire Protection System None existing. Electrical Systems General lighting in the building consists of fluorescent 2x4 acrylic troffers and surface direct fixtures in corridors, office spaces and classrooms, fluorescent in utility spaces, and miscellaneous specialty/decorative lighting in some spaces. Light fixtures are a mixture of old and new. All fixtures are in working condition, but the older fixtures are nearing the end of their useful life. Light levels throughout the building appear to meet IES recommendations for this type of building. Lighting control consists mainly of wall switches. Current energy code has requirements for turning lights off automatically that do not appear to be met for all spaces. Outdoor lighting consists of building mounted and pole mounted light fixtures. Some of the fixtures appear to be nearing the end of their useful life and may be in need of replacement. Newer lighting: 10+ years Older lighting: 5+ years Replace fixtures that are near the end of their useful life. Add automatic lighting control to spaces required by energy code. Power Distribution: The building is fed with 208V, 3 phase, 2000A electrical service from an outdoor utility transformer. An original 2000A service entrance switchboard is located in the basement electrical room. The original switchboard is past its useful life. The rest of the electrical panels appear to be aged, but in relatively Existing Facilities Survey Page 27

6 good working condition. An upgrade to 480V distribution would allow for more efficient power distribution and future capacity, but would likely be cost prohibitive, unless a complete remodel was completed. None of the electrical equipment is labeled for arc flash hazards. The classroom converted to the IT computer lab lacks proper power routing for PC tables. There are multiple fire hazards with power strips plugged into other power strips. This could be fixed with ceiling power drops to each table, or furniture feeds from the walls. Electrical receptacles and connections appear to be in good condition in remodeled areas and moderate condition in older areas. Surface raceway is common for routing power. Newer electrical panels: 15+ years Original switchboard: Past expected life Older electrical equipment: 5+ years Replace the original switchboard soon. Electrical equipment failures come without warning and can cause significant damage, especially on a switchboard of this size. If a complete remodel is not in the near future, then an upgrade to the older spaces is recommended to replace older electrical receptacles and equipment. Complete an arc flash study on existing equipment and provide proper labeling on all electrical equipment. Emergency Power: The building appears to have a separate metered service labeled emergency. It does not appear to be fed from a generator, and therefore only exists as a separate building feed, not as an emergency power source. The service appears to only feed a small disconnect for the fire alarm panel and a small 6-circuit load center. This does not actually count as an emergency system and would need to be fed by generator or battery inverter to be considered an emergency system. Some emergency lighting and exit signage is battery backup, but it s unclear if the egress lighting meets code required levels.

7 Photo 22-Emergency Load Center Panel Panels: 20+ years Provide a small generator or inverter system to feed emergency system. Upgrade EM panel to a 30-circuit service panel, capable of serving egress lighting loads and fire alarm loads, when the main electrical system is upgraded. If a complete remodel is not in the near future, then an upgrade to the older spaces is recommended to verify egress lighting is provided throughout corridors. The fire alarm system generally consists of code minimum smoke detection in miscellaneous spaces, pull stations at exits, and notification throughout the building. The fire alarm panel is an older system, Fire Lite MP-24. It looks well maintained, but new code requirements and updates to fire alarm systems will make this hard to maintain much longer. Much of the fire alarm has been installed using surface mounted conduit or raceway due to remodeling. The stairwells and some exits are missing pull stations and much of the notification coverage does not meet current code standards. 5+ years Upgrade fire alarm system, placing code compliant notification in proper locations and provide pull stations at all required locations. Telecommunications/Technology: The district central hub is housed within the building and serves all schools and the police department. The telecommunications system currently consists of single mode fiber, 62.5 multimode fiber, T1 lines from the service provider for data backbone and multipair copper for voice backbone infrastructure and category 5e and coax for horizontal (station) cabling. Community Antenna Television service is provided within the building. The district recently upgraded the phone system, network switches and provided complete wireless coverage for the building. 10+ years Upgrade the telecommunications infrastructure to support higher bandwidth on the network as the need arises. Optical fiber backbone cabling should be upgraded to 50 micron OM3 and horizontal cabling shall be upgraded to Category 6 at a minimum. The Access Control/Intrusion Detection system was recently installed district wide, which consists of card readers, electronic door locking hardware, door position switches, request to exit devices and motion sensing PIR devices. The access control/intrusion detection system is in good working condition. 10+ years Add card access to the server room for monitoring of entry to the district network room. A paging system is nonexistent. A bell system is is nonexistent. An audiovisual system is currently installed in the boardroom and consists of projectors, screens, and video conference. In addition, the gym currently has a local scoreboard and sound system. The boardroom audiovisual system is in good working condition and the gym scoreboard and sound system is outdated. Up to 5 years Replace scoreboard and sound system in gym if the functionality remains in the building. Priority 1 Recommendations Recommended upgrades/replacements in the near future due to life safety, code compliance, or security. 1. The student toilet rooms do not meet current ADA- ANSI requirements and should be looked at for upgrades and renovations. See photos 10 and The casework and counters in the OT/PT classroom do not meet the current ADA/ANSI requirements, See photo Revise corridor egress lighting to be automatic control.

Replace the fire alarm system and update fire alarm device layouts to meet current codes. 8. Add card access to District server room. 9. If major renovations are pursued, the addition of a fire protection system may be required depending on the scope of the renovation. An upgraded fire alarm system may allow renovations to occur without adding fire protection, however recommend adding a fire protection system if major renovations are pursued. Priority 2 Recommendations Recommended upgrades/replacements due to maintenance, energy, or end-of-life 10. The wood windows should be replaced for energy conservation. See photos 12 & Repair and determine reason for cracking in concrete block walls. See photo There are several interior doors that show signs of damage and should be replaced. See photo Replace damaged VCT in the gymnasium. See photo The EIFS control joints need to be cleaned out and resealed.

See photo Storm water management to address ponding issues. 25. Repair retaining wall. See photo Replace steam boiler. 27. Insulate condensate return piping. 28. Revise zone HVAC control strategy. Currently multiple rooms have two or three thermostats within the space which creates the potential for simultaneous heating and cooling. 29. Replace four of the six-rooftop units that were installed in Replace AHU s serving Gym, IT Office, and indoor unit located in Mechanical Room Remove unit ventilators and provide hot water fintube or fan powered terminal air boxes for perimeter zones. Overhead air system serves many rooms where unit ventilators are installed. 32. Revise classroom lighting to multi-level switching to improve efficiency. 33. Add automatic shut-off via occupancy sensors, BAS, and/or lighting control systems. 34. Replace old electrical equipment in areas to be remodeled. 35. Complete arc flash analysis and label panels accordingly. 36. The majority of the schools have corridor lighting circuited to be on 24/7, known as night-lights. These night-lights are all fluorescent fixtures. There are simple LED retrofit kits for four-foot fluorescent fixtures that will result in long-term energy savings if these lights are to remain on 24/7. Priority 3 Recommendations Recommended infrastructure upgrades/replacements if renovations occur 37. Repair damaged ceiling tiles. 38. Several of the hollow metal doors and frames are damaged and are rusting. See photo The concrete stoops are showing some cracking and thermal sequencing damage. 40.
