July 7, 2020

Project status
Permit amendment issued

In February 2022, the Vancouver Fraser Port Authority issued amendment PER No. 20-012-04 approving the continuation of works 24 hours a day, from Monday to Friday. A construction notice was sent to the community prior to work commencing.

About the approved amendment: approved works include formwork removal, fender panel installation, works to support installation of in-water piles such as splicing or welding pile sections together, and deck re-instatement activities, and placement of pre-cast concrete and associated formwork. No pile driving activity (installation or removal) will be conducted outside of regular construction hours. No works and physical activities shall take place on Sundays or holidays. Construction notification will be issued to the community prior to works commencing.

In July 2021, amendment PER No. 20-012-03 approved works outside of standard construction hours, 24 hours a day, Monday and Friday, between August 2021 and February 2022. A construction notice was sent to the community prior to work commencing.

In March 2021, amendment PER No. 20-012-02  approved an extension to the permit (which was due to expire June 30, 2022) to June 30, 2023. In-water works have been planned to occur during least-risk windows for the protection of fish and fish habitat in 2020-2021 and 2021-2022. Based on the latest schedule, a third in-water construction season is needed to complete the project. There are no changes to construction activity or the scope of the work.

In January 12, 2021, a minor amendment, PER No. 20-012-01, was approved by Vancouver Fraser Port Authority. The amendment approved work outside of standard construction hours (as set out in Permit condition No. 23) for specific works. These include formwork removal, fender panel installation, works to support installation of in-water piles such as splicing or welding pile sections together, and deck re-instatement activities. No pile driving activity (installation or removal) will be conducted outside of regular construction hours.

In June 2020, a project permit was issued to Shell Canada Products Ltd. (the Applicant), to replace four existing berthing dolphins and install a fifth berthing dolphin as part of repair and maintenance of the existing wharf structure at the Shellburn facility in Burnaby, British Columbia on federal lands managed by the Vancouver Fraser Port Authority. A construction notice was distributed to the community prior to the start of works.

The project was approved subject to 44 permit conditions that Shell Canada Products Ltd. must meet to ensure the project does not result in significant adverse environmental effects.

About the project

The project consists of the removal of 185 creosote-treated timber piles and the installation of 65 creosote-treated timber, and 25 concrete-filled steel pipe piles. Eight temporary 457 mm timber fender piles will be installed to secure construction-related support vessels, these temporary piles will be removed once construction is complete. All waste materials will be collected within the immediate project area, and transported to an appropriate facility for recycling or disposal.

Pile installation and removal will be carried out from a floating barge using a spud barge, materials barge, vibratory pile driving hammer, and impact pile driving hammer. Existing decking will be removed where necessary to facilitate the replacement of each new dolphin. Staged removal of sections of the existing decking will be performed with marine based equipment and the decking components will be removed, placed on a barge, and subsequently taken from site for disposal at an approved facility. Once construction of each dolphin is complete, the corresponding section of deconstructed decking will be reconstructed using new materials. The proposed deck removal and replacement work will be carried out either from a floating barge or from the top of the wharf. Marine vessel traffic would include a barge-mounted crane for pile installation, and tugs to assist in barge movement.

Works will be conducted in two phases focusing on each of the dolphin structures from east to west in sequence, with each phase occurring during the Fisheries and Oceans Canada (DFO) least-risk window during the 2020–2021 and 2021–2022 seasons (Area 28 – Burrard Inlet: August 16 to February 28). Phase 1 consists of the works associated with the eastern section of the berthing facility and the fifth new dolphin installation with in-water works conducted in the 2020-2021 least risk window. Phase 2 consists of the demolition and installation works associated with the western section of the berthing facility, with in-water works conducted in the 2021-2022 least risk windows.
