Retaining wall replacement

The Proposed Project

Mainland Construction Materials ULC proposes to replace their failing rip-rap apron and creosote pile foreshore retaining wall with a steel sheetpile retaining wall at their site at 220 Edworthy Way in New Westminster, BC. The works will protect their site from erosion and reduce the risk of rip rap being a hazard to their barge operations. Approximately 72 cubic metres and 18 creosote piles will be removed. Approximately 40 linear metres of steel sheetpile will be installed along the Fraser River's north banks. The space between the new sheetpile wall and the existing shoreline will be backfilled with approximately 792 cubic metres of 20mm or 40mm clear drain rock. A 10 inch perforated drain pipe will be bedded in the drain rocks to prevent flooding. Piles will be removed and installed with a vibratory hammer. Removal and installation activities will be from shore using a long-reaching excavator.
