BACKGROUND
Orange County Sanitation District (OC San) generates electricity at the Central Power Generation (CenGen) facilities. The internal combustion engines (three at Plant No. 1 and five at Plant No. 2) are fueled by digester gas. The engines are located within the CenGen Buildings.
RELEVANT STANDARDS
• Comply with California Public Contract Code Section 20103.8, award construction contract to lowest responsive, responsible bidder
• Protect OC San assets
• 24/7/365 treatment plant reliability
PROBLEM
The rooms where the engines are located are subject to malfunctions that can result in fires with catastrophic results. Two recent incidents occurred at the Plant No. 1 engine room that resulted from a failed engine overhaul. The faulting engine was shut down after the room was filled with smoke. Fortunately, no one was injured but an early warning system could have provided a quicker response. These rooms have smoke alarm systems that are difficult to calibrate and have not been in service due to false alarms. Because of the danger to workers, fire alarm protection systems are necessary to meet code requirements.
PROPOSED SOLUTION
Award a Construction Contract for CenGen Smoke Detection Improvements at Plant No. 1 and No. 2, Project No. FE20-09. This project will provide code compliant aspirated smoke detection systems, audio/visual devices, and manual fire alarm pull stations in the Central Generator Rooms at Plant Nos. 1 and 2.
TIMING CONCERNS
Upgrading the fire detection and alarm systems is required to comply with building codes.
RAMIFICATIONS OF NOT TAKING ACTION
If this project is not installed, early notification of potentially catastrophic events will not be available which could lead to significant risk to life and damage to OC San assets.
