Project Description

Antioch Library Electrical Upgrade Project

The project includes one building with a total of 11,803 SF to demolish and replace several electrical systems. The existing main switchboard will be replaced with a 600A switchboard to accommodate the lighting changes and provide capacity for future electrical services. The interior lighting system will either be retrofit or new light fixtures with energy efficient light emitting diode (LED) bulbs will be installed. In addition, new power outlets will be installed on the main library floor for public use. Lastly, the installation of power outlets triggers accessibility improvements for the building which includes accessible parking re-location, path of travel improvements from the parking lot to the main entrance, and public restroom upgrades.
