Deltaport Truck Staging Facility, Delta British Colombia

The site’s subsurface stratigraphy consisted of the following:

• 0.3m of topsoil and fill over natural soil;
• A silty crust to a depth of 5m with traces of organics and shell fragments;
• Underlying interbedded silt and sand to a depth of 10m;
• Followed by clean sand to a max. depth of 18m;
• Underlying deep clay silt extending well beyond 40m

The liquefaction assessment of the site location revealed a possibility of post-liquefaction settlement at depths less than 15m. Menard Canada Canada installed Dry-Bottom Vibro-Replacement to address this issue. A Cone Penetration Test (CPT) confirmed the required performance established by the Engineer on this project. The site is located at a major highway intersection and a relatively smaller real estate area. So, extra care was taken in the traffic management plan to reduce the congestion and any incidents on the site.
