2 2 Main School Building BLDG-112A Building Purpose Building Area Inspection Date July 25, 2016 Inspection Conditions Facility Condition Index System Deficiency Overview Administrative, Classrooms, Cafeteria, and Gymnasium 77,699 SF 102 F - Sunny The following table provides a summary of the systems and their respective conditions found by each discipline. System Subsystem Condition and Deficiency Overview System Condition Rating Exterior Exterior Walls The exterior of the building consists of a brick façade. Good Corrugated metal paneling clads the brick walls at the roofline. The exterior walls were observed to be in good condition except for a few isolated areas of deficiency. On the north side of the building, the brick and mortar were be eroding away in patches. Some mortar has deteriorated 1/2 inch deep and had organic growth. Near the same area, the soil also had eroded from under the exterior wall. Much of the metal panel cladding the building was rusting and had peeling paint. Exterior Windows The front of the school and the classroom wings have newer windows in aluminum frames with a louvered shade above. The glazing is single-paned. The classroom wings have two sets of glass block clerestory windows, one at the roof level, the other just above the vision glazing. The newer windows were observed to be in good condition, with only small areas of water spots on the exterior of the frames. The shades above the windows were observed to be in poor condition. Rust and peeling paint were prevalent. There is a portion of the school utilizing glass bock as clerestory windows. The entire zone is in failing condition. The frame of the glass block was rusted, and the roof adjacent to it was aged. The clerestory glass block window ribbons were completely covered by metal Poor

3 3 System Subsystem Condition and Deficiency Overview System Condition Rating siding. The glass block that was not covered was aged and had cracking sealant between blocks. The exterior windows of the gymnasium and the safety screens on them were very aged. Dust, gapping and cracking were observed. Condensation was observed inside some windows, accompanied by green organic growth, and rust was observed on the wall above many windows. Exterior Doors There is one main public entryway located at the east side of the building; these doors are glazed metal in a metal storefront system. The remaining service doors around the facility are metal, with and without glazing. There is one overhead rolling door providing access to the main mechanical room. This door is a manual aluminum 10-0 x 12-0 door. The exterior doors appeared to be in average condition due to age, high usage, and minor rusting. Peeling paint and scratched surfaces were observed on most doors and frames. Some hinges and frames were showing signs of rust. Many dents were observed on the overhead door. Average Roofing The roof systems present on BLDG-112A include built-up tar with a granular topping, single-ply membrane and modified bitumen. The areas around the roof drains are covered with modified bitumen, and much of the granular topping is actually on top of a modified bitumen roof. The built up and modified bitumen roofs were in observed to be in poor condition due to age. Much of the roof membrane was thickened and cracking. Roof segment A-06 was newer, but exhibited large folds in the membrane. Green discoloration was observed near the library clerestory windows. Excessive bubbling, ponding, and organic growth were observed on the entire roof segment A-11, which was installed in Roof segment A-08 was failing with completely deteriorated portions of roof membrane. Roof leaks were reported above room 200 and corridor C8. A portion of the built-up roof had piles of granular topping, exposing the sublayer beneath. The single-ply membrane appeared to be in average condition. Large areas of discoloration due to ponding were observed, and organic growth was observed on the walls. A ridge blocking the majority of gutter access was observed. Presumably, this was installed to direct water flow to the gutter at specified locations, but discoloration and wear were observed along the length of the ridge. The access ladders between roofs were unstable and did not extend high enough above the roof to provide safe access. Poor Interior Construction Interior Walls A portion of the school is built with brick walls, which are unpainted. The walls were observed to be in poor condition as a structural deficiency was present. A consequence of structural failure, the walls were offsetting from each other in various locations. This was observed in the Poor

4 4 System Subsystem Condition and Deficiency Overview System Condition Rating corridor and under the clerestories of the classrooms. Additionally, large cracks were observed in walls and at wall connections. Light chipping was observed on the corners of the brick walls. Interior Doors The interior doors in the building are comprised of metal Poor and wood doors in metal or wood frames. Some of the wood doors have narrow lites. Many of the doors have metal grilles, which are covered with metal plate on the inside. The interior doors were observed to be in poor condition as all classroom doors and frames were excessively worn. Interior Specialties System not present. N/A Stairs Exterior Stairs There is one wood stair and walkway leading from the Good faculty parking lot to the front door of the school building. The wood is painted. The stair and walkway appeared to be in good physical condition with no visible signs of damage. Interior Stairs There are two interior stairs in the building, both Average providing access to the library mezzanine. One stair is spiral and one is a standard L. Both have carpet covered treads. There are small wooden stairs to the cafeteria stage. The library stairs were observed to be in good condition, but one of the cafeteria stairs was observed to be in poor condition due to unstable floorboards. Interior Interior Wall Finishes The interior wall finishes consist of painted dry wall, Average Finishes wood paneling, and ceramic-faced masonry unit. The classrooms have 7-0 tall wood wainscots. The wall finishes appeared to be in average condition, because the wood paneling was observed to be in good condition, and the paint was observed to be in poor condition. Peeling paint was observed in many classrooms. One ceramic-faced tile wall was discolored from water streaks running down from the ceiling. Interior Floor Finishes The school floors are finished with linoleum tile and carpet, with tile in the restrooms. The library and administration area are finished in carpet. The gymnasium floor is finished with rubber athletic tile. The floor finishes were observed to be in average condition due to some isolated areas of deficiency. The gymnasium floor was scratched from normal use but appeared to be in good condition. Many dead roaches were observed on the kitchen floor. Calcium/lime stains Average

5 5 System Subsystem Condition and Deficiency Overview System Condition Rating were observed on the kitchen floor grout. There were some small stains on the library carpet, and a few cracked linoleum floor tiles. Interior Ceiling The classroom restrooms have lay-in ACT (acoustic Average Finishes ceiling tile). The gymnasium is ceiled with adhered ACT. The kitchen is ceiled with lay-in moisture-resistant panels. The ceiling tiles were observed to be in average condition as most of the ceiling tiles were bowed up at the corners. Water damage was observed on a small amount of tiles, including one tile in the library and a section of the gymnasium ceiling. Many of the gymnasium ceiling tiles were out of place and a few were broken. Conveying System not present. N/A Plumbing Plumbing Fixtures The building has public male and female restrooms and Average separate staff restrooms throughout the facility. These restrooms have vitreous china hand sinks, toilets, and urinals. The toilets and urinals have manual flushing valves. Service sinks are located in the janitorial closets near the stage, kitchen, and in the 200-wing. The restroom plumbing fixtures appeared to be in average condition. The majority of the fixtures were functional, but there were issues observed in several areas throughout the building. There was a water cooler located between the kitchen and the cafeteria that was aged and had low water pressure. Another water cooler located in space 127 on the mechanical plans was not functioning. The sprayer for the sink in the teacher s lounge was missing the trigger. The sprayer was not functional, but the faucet had water flow. There were toilets in rooms 115, 120, and 124 that did not flush properly. Several sinks in the 100-wing did not have water flow. The sink handle for the female restroom in room 119 could not be turned. For these reasons, the system was observed to be in average condition. Domestic Water Distribution The majority of the plumbing fixtures throughout the building are only serviced with cold water. The staff restrooms and kitchen area are serviced with hot water from either gas or electric water heaters. Average The water heater near the break room and administrative areas (EWH-2) was not accessible for assessment.

6 6 System Subsystem Condition and Deficiency Overview System Condition Rating The water heater located in the gymnasium storage closet was operating and appeared to be in good condition. The unit appeared to be new along with its distribution piping. The water heater located in the main mechanical room (MainMech) appeared to be in excellent condition. This unit had a note on the exterior that read, Installed on Although the water heaters looked new, the faucets in the kitchen area did not have hot water flow at the time of the assessment. The water heaters may have been off for the Summer, which would account for the lack of hot water flow. Other Plumbing The roof drains for this building have metal grate covers that are preventing debris from entering the drains. Some roof drains had more debris collected around them than others did. The roof drains were observed to be in good condition. Good Mechanical/ HVAC The major HVAC (heating, ventilating, and air conditioning) mechanical equipment consists of a cooling tower, centrifugal chiller, two boilers, indoor fan coil units in the classrooms, and packaged RTUs (roof top units). There are seven packaged units along with make-up air units, roof drains, and EFs (exhaust fans) located on the roof. The condenser unit for the administrative rooms, ACU-MDF, and one of the RTUs above the kitchen appeared to be in average condition. Two other units on the roof were observed to be in poor condition. Corrosion and wear and tear on the exterior was the most common deficiency for these units. Several of the indoor fan coil units were given an average or poor rating because of corrosion on the exterior of the unit or general aging of the equipment. The fan coil unit in room 103 has a hole in its exterior due to excessive corrosion. The supplemental HVAC equipment, such as the EFs, was observed to be in average condition. Some of the EFs had bent frames and showed signs of hail damage, while other EFs looked new and in good condition. The make-up air unit above the kitchen was observed to be in average condition. The metal grate for the air intake had some minor damage. Average Fire Protection Fire Alarm The building has a fire alarm system that consists of Average alarm and signaling devices such as horns/ annunciators, strobes, horn and strobe combination devices, pull stations, and detectors.

Electrical Electrical Distribution A 750kVA pad-mounted utility transformer serves a Poor 2000A, 480/277V main switchboard that is located at the exterior of the building by the dock area. The main switchboard has a bus rating of 3000A and has a 2000A bolted pressure switch main disconnect. In 1998, major electrical distribution system upgrades, renovations, and additions were completed, which included the addition of a 100kVAR power factor correction capacitor bank. Approximately 65% of the facility consists of newer equipment; the remaining 35% is original to the construction. There are active Federal Pacific panels present. Federal Pacific panels are known to fail catastrophically and are no longer manufactured. About 90% of the roof-mounted equipment does not have disconnect switches. It appeared that the disconnecting mechanism were integral to the equipment. The 10% of roof equipment that does have disconnect switches and/or starters appeared rusted and worn out. The electrical distribution equipment original to the construction was observed to be in poor condition. A majority of these assets no longer have replacement parts and had severe corrosion. It was also reported that circuit breakers that serve the administrative office, library, counselor s office, rooms , and rooms often trip. One panelboard was missing circuit breaker covers, and the bussing was exposed behind the dead front. This condition is considered a life safety hazard. Distribution panel MTDP appeared to not have sufficient working clearance in front of it. All disconnect switches/starters on the roof should appeared to be in poor condition. Lighting The building s interior lighting system consists of a combination of 2x4 recessed, 1x4 pendant mounted tubular fluorescent fixtures as well as compact fluorescent bowl type fixtures. All interior lighting controls are manual. The exterior lighting consists of building mounting HID (high-intensity discharge) fixtures Average

8 8 System Subsystem Condition and Deficiency Overview System Condition Rating which are building mounted. There are no pole mounted parking lot light fixtures. Emergency egress lighting and signage consists of ceiling and wall mounted exit signs and emergency egress lighting units (frog eyes). The 100-wing has 2x4 fluorescent troffers in classrooms and also pendant-mounted 1x4 fluorescent. There are compact fluorescent bowl fixtures in each classroom restroom which flicker profusely before they come to full brightness. When these fixtures come to full brightness, they make a continuous buzzing sound. This issue is typical for all similar surface-mounted bowl fixtures installed at this facility. All lighting control is manual. The 200-wing has lighting and lighting control conditions similar to the 100-wing. The cafeteria has 2x4 fluorescent troffers. Approximately 8% of these fixtures have lamps that are burned out and roughly 2% have broken lenses. The emergency lighting is limited, outdated, and nonfunctional. All lighting control is manual. The kitchen has 2x4 fluorescent troffers. The library has 2x4 lensed fluorescent troffers, and they appear to have been renovated in There is no emergency lighting. Lighting in the librarian s office is dim. All lighting control is manual. The gymnasium has fluorescent strip lights with wire guard. Approximately 15% of the wire guards are knocked out of place. There is no emergency lighting in the gymnasium. The gymnasium switchbank has a missing switch, leaving the wiring inside the box easily accessible. All exterior lighting is either outdated, worn out, or both. Exterior lighting consists of HID (high-intensity discharge) type building-mounted light fixtures. Approximately 65% of the exterior lighting was on during the daytime. The north parking lot has no lighting. The parent drop-off area has no area lighting and limited building-mounted lighting. The interior lighting appeared to be in average condition. Observed deficiencies included broken lenses, inconsistent color temperatures, and nonfunctional fixtures as discussed above. Life Safety Issue: All exit signs and emergency egress lighting appeared to be outdated and non-functional. All emergency egress lighting units (frog eyes) appeared to

9 9 System Subsystem Condition and Deficiency Overview System Condition Rating be very outdated and non-functional. The exterior lighting was observed to be in poor condition. Observed deficiencies included broken lenses, inconsistent color temperatures, non-functional fixtures, and fixtures that were on during daytime. Communications & Security There is a Gemini security system including surveillance cameras in the building. According to facility staff, the system is working with no issues to report. Interior corridor areas and the exterior dock area appeared to lack camera coverage. There is a public address system in the building, and it appeared to be in average condition. Speakers in the gymnasium were knocked out of place. It was reported that exterior speakers were not working properly. The building is equipped with telecommunications systems, but the main backbone equipment is located in an inaccessible room. Wi-Fi hubs throughout the facility were observed to be in good condition. Life Safety Issue: On the roof, fiber optic cables were laid out and exposed in a haphazard manner, with very poor workmanship evident in the overall installation. There are locations where these cables are a major trip hazard for facility maintenance staff/contractors working on the roof. This could be considered a potential life safety issue. The building has an analog clock and bell system, and it was reported to not function properly. Poor Exterior System Deficiency Examples Exterior Walls
