DESCRIPTION: This project is for the refurbishment of Bridge 10.10 located along the Sydney Coal Railway (SCR). The SCR is critical for the supply of solid fuel to Lingan Generating Station, linking Lingan to the International Coal Pier. T...

AI summary This project involves refurbishing Bridge 10.10 on the Sydney Coal Railway to ensure safe operation and fuel supply to Lingan Generating Station. NS Power conducted inspections and will replace bridge components while maintaining clearance and elevation. The Board's directive on the Decarbonization Deferral Account (DDA) requires NS Power to notify participants about future capital work orders, which was fulfilled on May 4, 2026.

Why do this project? The SCR is critical to ensuring the reliable supply of coal to the Lingan Generating Station. In 2024, all bridges along the SCR were inspected. Please refer to Confidential Attachment 2 for the 2024 Bridge 10.10 inspe...

AI summary The SCR is vital for coal supply to the Lingan Generating Station. Inspections revealed corrosion defects on bridge 10.10, reducing load-carrying capacity and causing non-uniform stress distribution. Structural analysis confirms inner girders exceed fatigue capacities, necessitating mitigation.

Why do this project now? This project needs to be completed now to prevent further deterioration of the bridge and refurbish impacted portions to an acceptable condition to ensure the SCR continues to meet Transport Canada requirements as...

AI summary The project must be completed now to prevent further bridge deterioration, ensure compliance with Transport Canada and AREMA standards, and maintain rail safety. Corrosion has reduced the bridge's load capacity, risking compliance with rail car travel requirements until coal-fired units retire. The project is deemed in-service in September 2026, with a Final Cost Date in June 2027.

Why do this project this way? The selected approach—refurbishing the superstructure while reusing the existing abutments—provides the lowest‑cost method to safely maintain the SCR through the anticipated coal-phaseout in 2030. The alternat...

AI summary The selected approach of refurbishing the superstructure while reusing existing abutments is the lowest-cost method to maintain the SCR through 2030. Replacing corroded girder cover plates would involve higher capital costs, longer timelines, and potential performance risks due to incomplete corrosion removal. Prefabrication and hoisting minimize coal delivery disruptions to Lingan.

Reason for Variance The decrease of $344,651 from the 2026 ACE Plan subsequent submittal estimate of $1,353,592 is due to decreased abutment scope requirements. Core sampling during conceptual design revealed existing abutment structural i...

AI summary The $344,651 reduction in the 2026 ACE Plan estimate stems from reduced abutment scope requirements, as core sampling confirmed existing structural integrity at lower speeds on the track segment.
