This project involved the structural rehabilitation of 350 steel piles utilizing the Fibrwrap® structural pile repair system. These piles support a large concrete wharf and Telus Science World located in downtown Vancouver, BC. Underwater welding and additional cathodic protection systems were installed to prevent further steel corrosion. All work was completed utilizing barge installation techniques in working with the tidal flows.
The City of Vancouver required structural upgrades to their Seawall, Expo and Waterfront concrete wharfs. Structural repairs were made to key defective sections of the suspended concrete deck using our SIKA Top 123® product and pile repairs were made using our Denso® pile jacketing system. Pile cap supplements were installed and new wood piles driven to fortify the wharfs structural integrity.
The Denso Seashield 100 was recommended to protect a select group of deteriorating dolphin piles. Working in a 25 foot tidal swing on the west coast of British Columbia made for a successfully challenging project that required a 30 foot vertical wrap and horizontal cross member HDPE wrap system.
This project involved the installation of over 1KM of HDPE raw water intake lines that would feed the DFO R&D Pump Station. One portion of the line was directionally drilled and the balance was fused on land, floated and sunk using guide weights and anchors. A complete mechanical and electrical retrofit of pump station was completed. Our dive crew supported the waterside efforts of this project.
This project involved marine pile driving of eight (8) new steel pile structures to support DFO Navigational Aids. All work was conducted off our Derrick with a 50 ton lattice boom crane. Structural welding was required to install the support frames and ladders to each structure.
