Nova Scotia Power filed responses to 16 Board information requests on the $1,008,941 Sydney Coal Railway Bridge 10.10 Refurbishment capital project (CI C0084033).
AI summary
- NS Power explained that the project's CI number changed from C0076672 to C0084033 because PowerPlan records for the original CI were lost during a cybersecurity incident and could not be recovered (IR-1(a)).
- The 46-year-old Bridge 10.10 has been assessed as having reached the end of its useful life due to corrosion-driven material loss that has reduced the load-carrying capacity of structural steel members below the AREMA Cooper E60 standard required for coal delivery to Lingan Generating Station (IR-2(a–b), IR-6).
- NS Power ruled out the alternative girder cover plate option because welding onto heavily corroded surfaces does not meet Transport Canada's Guideline for Bridge Safety Management and would require a longer coal-delivery outage; full span replacement was confirmed as the preferred solution by the engineer of record (IR-2(e)(i)).
- Trucking coal to Lingan was deemed non-viable on both safety and cost grounds: rail costs approximately $3.20/tonne versus $9.00/tonne by truck, implying roughly $2.9 million in annual incremental costs, and insufficient trucking capacity exists in the region (IR-2(e)(ii)).
- The structural analysis contract was sole-sourced rather than competitively tendered, justified by specialty rail engineering expertise and the need to schedule the bridge outage in 2026 at a time that minimizes risk of unplanned coal delivery interruptions to Lingan; consulting costs are withheld as confidential to protect vendor competitive interests (IR-8).
