Change Order: Traction Power Substations (TPSS) Rehabilitation Change Order #012 - New HVAC Systems (C3M Power Systems, LLC)
end
AGENDA ITEM TYPE:
Procurement Contract/Change Order
RECOMMENDATION:
Approve Change Order #012 to the TPSS Rehabilitation Contract with C3M Power Systems, LLC and authorize Executive Director to execute the change order and associated disbursements for new HVAC systems in the amount of $1,651,646.
BACKGROUND:
UTA has an existing contact with C3M Power Systems (C3M) to design and rehabilitate its Traction Power Substations (TPSS). This contract was approved by the Board of Trustees on June 23, 2021 and awarded to C3M on June 24, 2021. The substantial completion date for this contract is April 11, 2025.
As part of the base scope of work, C3M performed an evaluation of the nineteen (19) TPSS units listed in the contract. In this evaluation, the contractor discovered that the HVAC systems at eighteen (18) sites do not meet the design operating temperature range for the traction electrification system. The existing HVAC units often overheat and must be repaired. Increasing the cooling capacity will reduce maintenance costs and keep essential components cool enough to meet or exceed their intended life span.
DISCUSSION:
For this change order, C3M will install two 5-ton HVAC/heat pump systems at 15 TPSS locations and three 5-ton HVAC/heat pump systems at 3 TPSS locations. At the three 5-ton locations, the TPSS Auxiliary Transformers will be upgraded to 45kVA rating to accommodate increased power.
