Change Order: Traction Power Sub Station (TPSS) Rehabilitation Change Order #004 - Additional DC Breakers (C3M Power Systems)
end
AGENDA ITEM TYPE:
Procurement Contract/Change Order
RECOMMENDATION:
Approve change order #004 to the TPSS Rehabilitation Contract with C3M Power Systems, LLC and authorize the Executive Director to execute the change order and associated disbursements in the amount of $2,694,731.
BACKGROUND:
UTA has an existing contact with C3M Power Systems to design and rehabilitate UTA’s power substations. This contract was awarded to C3M and approved by the board on June 23, 2021. The substantial completion date of the base contract is February 28, 2025.
DISCUSSION:
UTA requests two (2) additional DC breakers for each of nine (9) substations to enhance future light rail operations. The addition of two DC breakers will allow better main line operations during contingency operations, allowing for more localized sectionalization and better maintenance access. This update includes the additional DC breakers, hardware, design, and additional fabrication incorporated into the base C3M TPSS Rehabilitation Contract.
The nine substations include:
1. SRD1 (Delta Center)
2. SRT2 (300 South)
3. SRN3 (900 South)
4. SRB4 (Burton)
5. SRH5 (Huslers)
6. SRW6 (Walton)
7. SRC7 (Central)
8. SRH8 (Murry)
9. SRP9 (Pallas)
The original scope of work prescribed that all nineteen Impulse substations would have the existing two DC breakers replaced. However, UTA and C3M found that the existing layouts could allow for the addition two DC breakers. This was also true for those substations scheduled to receive a larger sized transformer (note: the larger transformer is not anticipated to affect the electrical ratings of the breakers; however, this scope includes engineering to verify breaker ratings with the larger transformer). This change order will extend the contract end date by 42 days. The new substantial completion date will be April 11, 2025.
