In 2023 JDS Supported the Regional District Okanagan Similkameen in rehabilitating the Adra Tunnel located on the historic Kettle Valley Railway Trail. JDS mobilized equipment and personnel to support this unique project in support of mucking out the tunnel and reahabilitating the portals to support re-opening to public trail users.

Construction & Development (Completed – 2025)

In 2022, JDS was engaged by the Broadway Subway Project Corporation to support with the excavation of a conventionally mined tunnel on the inbound line TBM take-off point at the Great Northern Way Station. Once engaged, JDS completed all regulatory submissions including ventilation plans and successfully mobilized and completed the tunnel ahead of schedule with no major incidents. Based on the successful completion of the initial scope, , JDS has embarked on completing two (2) additional underpass tunnels, two 2 SEM large diameter tunnels, one vent shaft and 13  cross passages for the project while supporting several other station developments on an as needed basis.

In 2022, JDS was awarded a section of 5 m x 5 m tunnel development on Spread 5B of the TMEP, 10 km West of Hope, BC. The project involves drill and blast activities in close proximity to major federal and provincial infrastructure with extremely tight tolerances for specifications and peak particle velocity. The scope includes mobilization, material supply, 161m of development and installation of a final ground support requirements. In addition to this scope, JDS has engaged the TMEP’s directional drill contractors to supply a unique service in Casing Advance Obstruction Removal (CAOR) using traditional drill and blast techniques. This allowed the drilling to re-commence, avoiding major project delays and expenses. The Mountain 2 scope was fully completed in October 2023 with additional close-out scopes such as concrete bulkheads and pipe supports being wrapped up to close out the project.

JDS excavated underground wine storage tunnels and tasting room for Sureway Construction Group at O'Rourke Winery in Lake Country, BC. The project included 270 linear meters of 5m x 5m development, 50m of 2m x 3m mandrift and drop raise, and three primary portals, with varying tunnel profiles up to 8m wide depending on end use and depth. JDS prioritized quality, aesthetics, and long-term stability over advance rate, performing all underground project management, engineering, mining, and ground support on a fixed cost-per-meter basis while maintaining flexibility as design concepts evolved.
