Northwest Luncheon – Edmonton, AB

Join us for an educational luncheon on the Capital Line Storm Storage Tunnel project is part of the early works scope for the Capital Line South LRT Extension.

The Capital Line Storm Storage Tunnel project is part of the early works scope for the Capital Line South LRT Extension. The project includes a construction of a 1000m3 capacity storm storage tunnel for groundwater and surface drainage, along with a lift station and forcemain that discharges stormwater to the existing trunk along 23 Avenue. Design of the tunnel required the future LRT underpass to drain into a gravity tunnel beneath and drop into a storage tunnel to be pumped out at low flow periods. This presentation will go through the process of the design decisions which pushed the tunnel and lift station to depths exceeding 20m, also the tunnels storage volume and various connections needed. Construction challenges will be reviewed as well as lessons learned from the work.

Presenter: Chris Lamont, C.E.T, P.Eng

Chris is a civil engineer with 15 years of experience in engineering, construction inspection and surveying. Chris conducts feasibility assessments and designs of trenchless methods which include tunnelling, microtunnelling, horizontal directional drilling, auger boring, pipe ramming, sliplining, and Direct Pipe municipal as well as infrastructure using conventional installation. He provides support across the company on civil infrastructure projects focusing on the application of various trenchless methods.

Presenter: Sam Saunders, P.Eng

Sam is a civil engineer specializing in trenchless technologies for linear infrastructure projects. Sam is responsible for the assessment, design, and implementation of both trenchless new installations and rehabilitation works. He has experience with a variety of methods including microtunnelling, horizontal directional drilling, cased crossing installation methods, hand tunnelling, sliplining, cured-in-place pipe lining, and spray-applied pipe lining.
