801BidSubmissions@CSC-SCC.GC.CA The 400A 3Ph breaker that supplies power to Kiosk SK-1 (located near Living Unit 1) of Mountain Institution has been experiencing irregular tripping, particularly more frequently during the rainy season. Professional contractors have recently conducted tests on the feeder wires and confirmed that they have failed the insulation tests. The underground conduits from the powerhouse to Kiosk SK-1 span approximately 380m, with the existing feeder consisting of 4 x 500MCM RW90 - 1000V copper wires. To ensure the safety and continuous operation of the power distribution system, CSC must replace the current copper feeder wiring between the Powerhouse and KIOSK SK-1. The Contractor must perform the following tasks: Thoroughly assess the site conditions.
Submit lock out procedures, professional liability insurance, health and safety plan and all documentation required to CSC.
Submit shop drawing of proposed new wires for approval before ordering material.
Remove existing wiring and install new copper wiring of the same type and size (4x500MCM RW90 - Copper - 1000V). The approximate length of the existing wire is 380 meters (times four). The Contractor must verify the exact length required prior to ordering materials. The new wires must be CSA listed / ULC approved. Additionally, the Contractor must supply a new bare copper bonding wire (sized per CEC) along the existing conduits' route, connecting it to both ends and to the metal parts of the manholes along the path.
Clean and re-use existing underground conduits and clean up existing underground manholes between the powerhouse and Kiosk SK-1. If any problems arise with the existing conduits, the Contractor must notify the departmental representative before continuing with the task.
Prior to terminating the new wires at both ends, conduct continuity and insulation (1000V megger) tests on the new wires. The Contractor must submit a copy of the test reports upon completion.
Dispose of any waste material, created during installation, from the site. Existing cables to be assessed by Departmental Representative and the Contractor to determine if there is any value in keeping at site for future repairs.
Coordinate power shutdown of main distribution board in the powerhouse and the restoration of utility power with the Institution. The Contractor must provide 96 hours' notice to the Departmental Representative before the power shutdown. The power shut down can take place on a weekday during the institutions normal business hours, 07:30 - 16:00 hours. One power shutdown is allotted for the Contractor for site termination breaker within the main distribution panel.
Check and verify the phase rotation of the feeder before and after the replacement of the wires.
Check and confirm the existing lugs at the terminals on both ends and replace where required.
Adhere to the facility's entry procedures and protocols for bringing tools, equipment, and vehicles to the site.
