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. condition. The main panel feeds 4 branch panels (Figure E8) . The pump appears to have a bonding wire running to the pool shell steel (Figure E9) . The bonding lug at the pool pump appears to be corroded. 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. Electrical recommendations include: The Smith Center has a 120/208V, 800A main electrical panel (Figure E7) . The main panel is in good

Exterior of the pool house at Lindley Park

Exterior The exterior of the pool house building is composed of painted CMU and wood paneling with hollow metal doors (no thresholds) and aluminum windows. Spot repairs appear to have been made in several door, window, and louver locations with dissimilar materials that have deteriorated. The top of wall fascia is a painted panel with a two-piece metal coping at the top of the wall/fascia. The roof is covered with a ballasted EPDM roof. At the time of the site observation, a section of the roof was missing the ballast covering. A metal awning covers a concessions window outside of the pool’s perimeter fencing. Exterior recommendations include: › The painted CMU wall, painted fascia, and metal coping are all in good condition with the wall and fascia requiring new paint. The remaining elements of all non-CMU wall surfaces, doors, windows, and joint sealants are beyond their useful life and require replacement. › While the EPDM roof membrane is protected by ballast and appears to be in fair condition with no visible leaks, the membrane seams and flashings are all worn and in need of repair. Recommend replacing the roof membrane, flashings, and coping. › Recommend removing the metal awning over the concessions window outside the fence and replacing with a more integrated canopy design.

› Replace the bonding lug at the pool pump and where the conductor is spliced.
