Contract: Traction Power Substations Rehabilitation Design Build (C3M Power Systems)
end
AGENDA ITEM TYPE:
Procurement Contract/Change Order
RECOMMENDATION:
Approve award and authorize Executive Director to execute the contract and associated disbursements for the Base Scope Work and Option No. 3 (Atwood Disconnect Switch Replacement) with C3M Power Systems in the amount of $38,077,408
BACKGROUND:
This request is to execute a Design-Build contract related to the rehabilitation of 19 traction power substations (TPSS) along UTA’s TRAX lines. UTA has advertised and selected a Design-Build Contractor through a Best Value selection process for the TPSS Rehabilitation Project (Contract #20-03378VW). C3M Power Systems was selected based on highest score and therefore is the most advantageous bidder to UTA. UTA would like to enter into a Design-Build Contract with C3M to begin work on this project. The substations are primarily located along the North/South Blue Line which makes up the trunk of the UTA TRAX’s alignment. In total there are 19 substations that were installed between the years of 1998 to 2003. The substations are mainly prefabricated units with one substation being located in an underground room in a parking structure. Of the 19 substations, 13 feed the North/South line and 6 feed the University Line. These older style substations do not have any data logging, remote control or SCADA capabilities and as a result the real-time condition of each of these substations is not known by the operations control center. This project will allow the entire substation system at UTA to be integrated into one central control center once the project is complete.
DISCUSSION:
The Base Scope of Work for the substation rehabilitation activities will consist of replacing the DC switchgear in all 19 substations and expanding the SCADA system to each of these existing locations. In 10 of the locations the rectifier-transformer will be upgraded from a 1.5 MW system to a 2.0 MW system. The existing pole-mounted disconnect switches will be converted to pad-mounted disconnect switches. This contract contains a base work package and three additional optional work packages, each of which may be exercised in the sole discretion of UTA at any time during the contract term and in no particular order. Option No. 1 includes replacing the existing positive feeder cables of nine of the TPSS rehab locations. Option No. 2 includes replacing the existing negative feeder cables at the 19 IMPulse TPSS locations and the Atwood TPSS locations - 20 locations in total. Option No. 3 includes replacement of the Atwood Disconnect Switch. Option Nos. 1 & 2 are not being exercised at this time. Staff will come back to the Board for approval if and when Options No. 1 and 2 are exercised in the future. Option No. 3 is being exercised concurrently with the base work package. UTA staff is requesting approval to enter into a contract with C3M Power Systems for this Substation (TPSS) Rehabilitation project, which will account for the rehabilitation of 19 substation locations, integrating a SCADA system for these locations, and providing all services as described in the RFP and in the TPSS Rehabilitation contract.

ALTERNATIVES:
Alternatives to this contact: • Replace all 19 IMPulse TPSS’s with all new substations. The cost to do this is estimated to be at least double the current contract amount. • Delay the IMPulse TPSS rehabilitation project to a later date. The risk to delay this project is considered unacceptable due to the current sage and state of the TPSS locations in this contract.
FISCAL IMPACT:
The budget is included in the current 5-year Capital Plan, 2021-2025.
