SUBJECT: GAS DETECTION ANALYZER SYSTEM
ACTION: AWARD CONTRACT
Heading
RECOMMENDATION
Title
AUTHORIZE the Chief Executive Officer to award contract No. PS21904205074 to Reliable Monitoring Systems (RMS), in the amount of $1,159,860, to provide a Gas Detection System (GDS) for Metro Red Line (MRL) and Metro Gold Line (MGL).
Issue
ISSUE
In order to ensure the safety of our passengers and staff in the underground stations and right-of-way, a complete replacement of the Gas Detection System equipment is required. This procurement is for the parts and installation of the new system.
Metro rail underground stations are equipped with gas detection equipment. The gas detection devices were installed throughout the stations and cross passages. In the event that harmful gases are present, an alarm is triggered at the Rail Operations Control (ROC). Staff is immediately dispatched to assess and mitigate the issue. The current GDS devices were installed throughout the MRL in 2002 and underground MGL stations in 2003. In addition, the GDS' main controller interface boards and peripheral equipment are obsolete, and replacement parts are difficult and expensive to obtain.
Discussion
DISCUSSION
The new GDS will replace and upgrade the current MRL and MGL equipment. This new microprocessor-based system performs functions including management of sensor modules, alarm relays, and interface with front panel display. The current equipment requires a labor-intensive system calibration every three months.
New GDS equipment has an original equipment manufacturer recommendation of bi-annual calibration resulting in operating cost savings by reducing the labor cost by half. This system will improve the speed of data information communications and accuracy of incident response time. Also, the system will be connected to the Supervisory Control and Data Acquisition (SCADA) system.
