Scope of Work

Background: C-TRAN's Administration Building lost power due to a reported accident on 112th Ave. Staff reported to the building finding the generator was running but no power was transferring to the building. The Automatic Transfer Switch (ATS) was inspected and found to be receiving power and was able to be manually activated. Once activated, emergency power was restored to the building to continue operations. As utility power was restored the ATS had to be manually deactivated and backup generator shutdown.

C-TRAN’s 51st Circle Facility at 10600 NE 51st Circle, Vancouver, WA 98682, is served by an ATS that connects incoming utility power to an on-site backup generator, providing continuous power to critical building systems, including a Server Room supporting Uninterruptible Power Supply (UPS)-backed equipment. The existing ATS requires repair and/or replacement to restore full, safe, and reliable automatic operation between utility and generator power sources. Because scheduled maintenance work on the ATS will require the transfer switch itself to be taken offline, C-TRAN also requires temporary generator connections to the Server Room’s UPS systems in order to maintain continuous, zero-downtime operation of Server Room equipment throughout the ATS maintenance window.

Contractor shall provide all labor, materials, equipment (including temporary generator to maintain power while work is completed), permits, and supervision necessary to inspect, test, troubleshoot, and repair and/or replace the existing ATS, including all associated controls, wiring, and connections, to restore the transfer switch to safe, code-compliant, fully automatic operation. All work shall be performed in accordance with manufacturer specifications; NFPA 110 (Standard for Emergency and Standby Power Systems); NFPA 70E (Standard for Electrical Safety in the Workplace); applicable National Electrical Code (NEC) requirements, including Articles 700, 701, 702, and/or 708 as applicable to the system’s classification; and all other applicable codes and site safety requirements. Work shall be performed by a Washington State L&I-licensed electrical contractor employing appropriately licensed journeyman or master electricians.

7.1 Temporary Generator Connection for UPS Systems during ATS Maintenance

The objective of this portion of the Scope of Work is to safely install temporary power connections on two (2) separate UPS systems located in the Server Room, allowing a temporary mobile generator stationed in the parking lot to feed power directly to the UPS systems. This will ensure continuous Server Room operations and zero downtime during scheduled ATS maintenance.

Phase 1: Pre-Maintenance & Engineering

- Load Verification: Audit and verify the electrical load specifications (amperage, voltage, phase) of both UPS systems to match the temporary generator output.

- Cable Route Planning: Map out a safe path for the temporary heavy-duty power cables, working with C-TRAN's Contract Manager, (e.g., SOOW cords) from the parking lot generator into the Server Room, utilizing existing conduit paths, windows, or designated cable ports.

- Safety Barriers: Deploy cable ramps and high-visibility safety markers in the parking lot and walking paths to eliminate or minimize tripping hazards.

Phase 2: Installation of Temporary Connections

- Breaker De-energization: Safely isolate and lock-out/tag-out (LOTO) the primary input feeds to the UPS bypass/input breakers.

- Plug Modification: Install industrial-grade temporary male inlet plugs (pin-and-sleeve or Cam-Lok style matching the generator requirements) onto the input terminals or temporary maintenance bypass lines of both UPS units.

- Cable Deployment: Lay down and secure the temporary power cables from the parking lot generator position into the Server Room.

Phase 3: Reversion & Demobilization (Post-ATS Maintenance)

- System Rollback: Once ATS maintenance is complete, safely transition the UPS inputs back to utility/house power.

- De-installation: Disconnect and completely remove the temporary plugs and cables.

- Cleanup: Clear all safety ramps, secure the Server Room electrical panels, and restore the site to its original operating state.

All materials furnished under this Scope of Work - including but not limited to ATS components, temporary power cables (e.g., SOOW cord), and pin-and-sleeve or Cam-Lok connectors and inlet plugs - shall be new, manufacturer-approved or equivalent replacement parts suitable for the intended voltage, amperage, phase, and application. Any additional parts or scope changes outside the original scope must be approved prior to installation by C-TRAN’s Contract Manager covering this project.

Contractor shall conduct a functional test of the ATS following repair or replacement to confirm proper automatic transfer operation, timing, and signaling between utility and generator sources, and to confirm all essential safety systems are in working condition. Contractor shall also verify that all temporary UPS/generator connections have been safely installed and tested, and that - upon completion of ATS maintenance - all temporary connections have been fully removed and reverted to normal utility operation as described above. Dispose of all removed and/or replaced materials off-site, and clean and restore all work areas, including the Server Room and parking lot, upon completion of the project.

8. Quotes are considered firm for a period of 60 days from the date of the quote submitted. Should C-TRAN seek to go beyond that period, C-TRAN may request in writing for bidders to extend the pricing for an additional 30 days for a total period to not exceed 90 days.
