› Lockers have been removed from the spaces leaving four-inch concrete pedestals along the perimeter wall. Recommend reconfiguring the space and fixtures to create an accessible route through the building and improve accessibility and privacy of water closets and showers. › As noted in the exterior section, the southeast corner CMU cracking will need to be reevaluated after geotechnical review. Plumbing The main pool area does not have a hose bibb for general maintenance. There is no drinking fountain pool side due to Covid. The plumbing fixtures are in fair condition. Requires cleaning. The pump room was reported to be noisy. Plumbing recommendations include: › Install new hose bibb around pool for general maintenance. Clean plumbing fixtures. Option to install water saving flush valve plumbing fixtures. › There are currently no single occupancy restrooms/shower/changing facilities. It is recommended to add at least one when doing a renovation or new construction. Mechanical Ventilation of the pool equipment room and the chemical storage room are provided by a combination of exhaust fans and louvers. Some notes on the wall indicate that there is not adequate ventilation in these spaces. Restrooms are unconditioned and provided with exhaust fans. Mechanical recommendations include: › Review ventilation system of the pool equipment room and the chemical storage room to increase air flow. Provide heat as necessary. Electrical The grounding test results of April 2021 were reviewed. The National Electrical Code, NEC, requires any metallic components of a pool installation within three feet of the inside of the pool wall to be bonded together. The bond is usually achieved through the

tie wires connecting the reinforcing steel and copper wires bonding from the pool accessory cups back to the reinforcing steel. A #8 bare copper wire ring is also installed around the pool and connected to the reinforcing steel at four points or more. The resistance in ohms of 1,000 feet of #8 copper is 0.6 ohms. The resistance of a bonding lug connection is between 0.01 and 0.03 ohms. Consequently, the expected resistance between one accessory “cup” and another would be around 1 to 5 ohms. If the measurement is larger than that, then it can be expected that corrosion has taken place. The pool house has a 120/208V, 225A main electrical panel (Figure E20). The main panel is in fair condition. The main panel feeds a 100A pump room panel (Figure E21) . The pump room panel is in fair to good condition but is unsafe to reach. There is a pit in front of the panel (Figure E22) , requiring someone to balance on the top of a dividing wall to reach the panel. NEC 680 requires a minimum #8 solid copper wire to be run from the vicinity of the pool pump motor to the equipotential bonding grid under the pool deck. We didn’t find this bonding wire and note the test results on the equipotential grid indicate an increasing loss of bonding. Electrical recommendations include: › Remove the pool apron around the perimeter and within 3 feet of the inside wall of the pool to expose the equipment cups, the reinforcing steel, and the equipotential bonding means. Install a new bonding with a bare #8 solid copper conductor. Extend the bonding wire to inside the pump room and adjacent to the pool pump. Install new equipment cups and bond to those cups to supplement the equipotential bonding grid. Then repair the apron. › Relocate the existing pump room panelboard and pump controls. Provide new bonding and new branch circuits in Pool Equipment room. Provide new feeder to pool panel.
