Title: Ottawa Stage 2 LRT: Shoring Decision Making at the Pinecrest/Connaught Tunnels
Description: The Kiewit Eurovia Vinci (KEV) Partnership are completing the Design-Build Ottawa Stage 2 LRT Project. The project includes a new 27 km LRT extension of the Confederation Line and includes 3.4 km of cut and cover tunnels and significant highway widening and structures scope. Brierley Associates supported KEV by providing temporary support of excavation system designs for various segments of the 10m deep open-cut trench excavation through soils and rock. This talk will focus on the Pinecrest and Connaught tunnel segments along the west end of the project, to highlight the technical and logistical considerations involved in installing the concrete box-structure within the open-cut trench.
