Cobourg Railway Station

On this project, HCM, in conjunction with its in-house engineering company, RWH Engineering Inc. (RWH), was able to offer the owner one source for the design, supply, and installation of a complete temporary shoring system and precision monitoring services.

RWH produced an efficient design that conformed to AREMA railway standards and resulted in savings to the owner, in comparison to the original tendered drawings. The RWH design included a double pile and lagging system with 17.5 meter long tiebacks, required due to the soft soils. In addition, HCM installed 275 mm diameter permanent micropiles at the base of the shoring. The micropiles extended through 12 meters of soil and were founded 5 meters into bedrock to provide the required capacity.

The general contractor benefited from working with a single source that could take responsibility for all aspects of the shoring and deep foundations work – guaranteeing quality and reducing costs.
