Contract No. 18143 - Electrical Construction for Depke Fire Alarm and Door Control Replacements

PROJECT DESCRIPTION: This project contains three scopes of work which the County intends to procure via a single qualified ELECTRICAL CONTRACTOR as part of a coordinated project.  FIRE ALARM: Three distinct Fire Alarm Control Panels are currently located on the campus.  Each of the panels is tied to the others to allow some level of campus wide notification during trouble or alarm events, though the systems are not fully integrated.  The intent of this project is to replace two of these systems, and add one additional panel, as well as a systemwide display unit.   All of these new devices will then be integrated with the existing (newly installed) 3rd panel to achieve a complete and operational fire alarm system.  Mass notification and PA address functionality will also be achieved via the designed system.  PLC & INTERCOM REPLACEMENT: Detention Areas of the Depke JJF utilize a programmable logic controller and intercom control module, both of which have reached the end of their useful lives.  This project will provide new detention doorway and intercom head end control modules; and new PLC relay devices at three wiring termination hubs.   The systems will integrate door locks, intercoms, and adjacent detention cameras into a touch screen control panel in the facility’s Central Control Office via a newly installed fiberoptic loop.  There are several door, door hardware, intercom, and camera modifications that are included in this scope of work.   UPS, Hydrogen Detection & Misc. Other Components: A new centralized UPS system and hydrogen detection system will be provided in Server Room 301F.   All point to point electrical work including panels, conduit, wiring and required access to install these components (removing and replacing ceilings, wall sleves, etc…) shall be considered part of this scope of work.
