ACTION: APPROVE CONTRACT AWARD
Heading
RECOMMENDATION
Title
AUTHORIZE the Chief Executive Officer to award a firm fixed price contract, Contract No. MA105918000, to Mac Products, Inc. for 232 Spring Tension Assembly units and onsite installation support for the C Line OCS System Overhaul Project for a firm fixed price of $3,121,820.86, inclusive of sales tax, subject to the resolution of any properly submitted protest(s), if any.
Issue
ISSUE
This procurement is to purchase Spring Tension Assembly units for the C Line Overhead Catenary System (OCS). The existing Weight Stack Assembly (WSA) units on the C Line are aging and near the end of their useful life. The Spring Tension Assembly units are a replacement for the existing WSA units. Currently, the Maintenance & Engineering (M&E) crew is working on overhauling the OCS and replacing all worn-out parts on the C Line OCS, including the worn-out WSA units. The replacement of these units during the OCS overhaul will minimize operation interruption.

The Metro C Line opened for service to the public in August 1995. Most of the OCS system components, including the WSA units, need to be overhauled, and the WSA units are recommended for replacement according to Metro's Transit Asset Management (TAM) database. Extensive maintenance has been necessary for the existing OCS WSA units to ensure the reliable operation of the OCS. The trains connect to the OCS wires through a train-mounted pantograph, which powers the train's movement. The WSA units constantly provide tension to the OCS wires to keep them at the required height. Due to the aging conditions of the WSA units, issues within the OCS poles arise from stuck wires, resulting in reduced tension on the OCS wires. If the OCS isn't held to the appropriate...
