Pleasanton Century House Assessment Report March 30, 2019 Page 5 Mechanical The existing mechanical equipment, ductwork, registers and controls are not compliant for a non-residential facility. All equipment is recommended to be replaced with new systems and materials appropriate for the proposed use of the facility. Plumbing The existing plumbing fixtures, piping and water heater are not compliant for a non- residential facility. All equipment is recommended to be replaced with new systems and materials appropriate for the proposed use of the facility. Electrical In general, the electrical distribution systems appear to be in a general state of disrepair. This approximately 2,400SF building area. has a 120/240 volt, single-phase, 3 -wire service with a combined total of 125 amps of service disconnects, plus a 60 -amp sub panel. This equates to an average capacity of about 13 watts per SF, which is toward the lower end of the 15-20 watts per SF. range typically provided for commercial buildings. The.PG&E meter assembly and service entry,appears to be in serviceable condition. The vegetation in front should be cleared for proper access. For new commercial use, it is recommended to upgrade the service and main circuit breaker assembly: 200A (amp) single phase service minimum. Visible branch circuit wiring appeared to be Romex style, insulated free air wiring. There were several instances where the insulation on the wiring could be seen deteriorating, exposing the conductors. The recommendation would be removing and replacing all wiring and branch circuit devices throughout the structure. A typical commercial project would include all wiring to be protected in conduit. The proposed re -wiring of the facility may involve the use of romex, MC cable or emt conduit depending on City Building Official input. The building -mounted incandescent and fluorescent lighting fixtures are located throughout the building. None of the light fixtures are period for the original construction of the structure. There are no CA Title 24 lighting controls installed. There is no emergency egress lighting installed and there are no exit signs located throughout the space. Exterior, building -mounted incandescent, fluorescent and halogen lighting fixtures are located around the perimeter of the building, but operation. could not be confirmed during the daytime observation. Based on location of the fixtures, it is believed that illumination levels around the exterior of the building would not be adequate. All interior and exterior building mounted lighting should be replaced with new LED fixtures, Title 24 compliant controls, and 90 -minute emergency battery backups where required for egress. 28o Bettencourt Street, Sonoma, -CA 95476 www.jeffkatzarchitecture.com
