Redredging – Paramount Site, Steveston

Public Works and Government Services Canada
Richmond, BC

In 2016, JJM Construction Ltd. completed redredging of the Paramount Site in Steveston Harbour. The dredging work was intended to enhance navigability of Cannery Channel and adjacent dock facilities, and had to be carried out with great care and precision due to the presence of existing dock, float and wharf structures in the work area. The work involved dredging in close quarters between wharf finger floats as well as more accessible side channel areas.

Disposal methods for the material included in-river disposal-at-sea (DAS), disposal at an approved DAS site at Point Grey, and disposal via cutter-suction dredging to nearby Shady Island. Accumulated sediments were removed from between the wharf floats and most of these sediments were pumped approximately 900 m across the channel to an upland disposal area on Shady Island. 

JJM also performed all the hydrographic surveying to track the progress and accuracy of the dredging, and prepare the as-built drawings.n conjunction with the Rail Installation.
