DESCRIPTION: This project is to rebuild the L-5046 tap at its intersection with L-5017, which is in the Wolfville, Annapolis Valley area. The tap structures and switches at this location were identified as requiring replacement as part of...
AI summary This project involves replacing 9 transmission structures and installing a new switch (83V-504) at the L-5046 tap in Wolfville, Annapolis Valley. The work is divided into two phases, aiming to enhance operational flexibility through on-load switching and a permanent bypass. Upgrades will improve transmission system reliability and isolation efficiency.

Assumptions Scope of work assumptions as per the NSPI request are: - NSPI Standard design criteria applies (NSPI Transmission Line Design Standard Rev02). - Standard checks of all wires/structures for strength, clearances, swing, etc. will...
AI summary The assumptions outline the scope of work for NSPI's transmission line project, including design criteria, standard checks, modeling using M4 structures, and exclusion of a new switch. Inputs such as LiDAR data and PLS-model will be provided.
1. Introduction To support the addition of a transmission Right of Way (ROW) switch to 69 kV transmission line L-5017, Nova Scotia Power (NS Power) requires an engineering service provider to create an Issued for Construction (IFC) drawing...
AI summary Nova Scotia Power (NS Power) requires an engineering service provider to develop an Issued for Construction (IFC) drawing set for a 69 kV transmission line (L-5017) upgrade, including physical, civil, and transmission components, to support the addition of a transmission Right of Way (ROW) switch.
Switch Structure NSPI transmission standards will be used as the basis for essentially all scope elements outlined in this SOW. However, specifically related to the switch structure's connections and steel components, CBCL will apply the N...
AI summary NSPI transmission standards will guide most scope elements, but CBCL will apply NS Power standards for switch connections and steel components without full analysis, assuming adequacy. Dimensional compatibility checks will be performed, with modifications requiring NSPI engineer input. No fence is included for switch site protection, though a pullover area for vehicles is noted.
