Construction of Westridge Marine Terminal (WMT), as part of the Trans Mountain Expansion Project (TMEP or Project), is expected to begin in September 2017. The Kiewit Ledcor TMEP Partnership (KLTP) has been formed for the construction of TMEP in the Lower Mainland, which includes 35 km of the pipeline from Langley to Burnaby, the Burnaby Mountain Tunnel, Westridge Marine Terminal, Burnaby Terminal and Sumas Terminal. To support WMT construction, KLTP has identified temporary use of lands in or near Burrard Inlet; as most of the construction for, and access to, WMT will occur from the marine waterway.

Temporary land use is required for a variety of Project construction activities, which include hosting contractor yards and offices, stockpile sites for materials and equipment, and processing areas to facilitate the on- or off-loading of materials.

Temporary sites are evaluated based on a number of considerations, such as location, road access, prior land use and feedback from stakeholders. A site is chosen in keeping with the Project objectives to minimize potential impacts to communities and maximize economic opportunities, while ensuring the safe and efficient construction of the Project.

Location

KLTP is currently exploring temporary use of a site within Vancouver Fraser Port Authority (VFPA) jurisdiction at 2115 Commissioner Street in Vancouver, BC for construction-related activities. The proposed temporary site was occupied by the original tenant for more than 85 years (VersaCold – a cold packing facility).

Located in the western end of the East Vancouver Port Lands (EVPL) area, the proposed temporary site is separated from the surrounding residential community by Commissioner Street and a CP Rail right-of-way. See Figure 1 for a map of the location.

KLTP recognizes the longstanding and respectful relationship VFPA has established with the communities adjacent to port lands; represented locally by the EVPL Committee. As such, KLTP is respectful of local resident concerns to what changes of activity could be on the site, including any changes to viewscape and marine activity to service the site.

Potential Temporary Use

Subject to Project Permit approvals by the VFPA, the main intended purpose for Site 1 is a marine off-loading facility and laydown yard for the Project. Other activities include parking on both Site 1 and Site 2 and the transport of construction workers by bus or water taxi to the worksite at WMT.

Site 2 operations will begin in October 2017 and could be in operation until the end of May 2020. This includes parking, shuttle bus and water taxi activities. 

Site preparation for Site 1 is planned for early 2018, subject to VFPA Project Permit approval. Site 1 is expected to be in operation from the end of February 2018 to the end of May 2020 (site timelines are subject to change).

At the end phase of the Project, KLTP will remove all temporary structures, materials and debris on site and perform a full site cleanup to restore the premises back to its state pre-occupation by KLTP.

Construction – Site Preparation

During construction for the temporary site, KLTP and its sub-contractors will access the site over an eight-week period to complete the site preparations. KLTP anticipates one to two contractors will be on-site each day, each having crews of up to 10 people arriving in personal and/or company vehicles. Marine contractors involved in the dock construction may also access the site via water.

What to expect on-site

A number of activities are planned to prepare the site for Project use:

  • Minor cleanup and site grading including the removal of any debris left on-site and filling in of pot holes
  • Placement of precast concrete barricades and fencing to delineate the Old Wharf due to various structural deficiencies
  • Installation of two cranes for material handling at the dock (sample pictures for illustrative purposes):
  • Installation of high standard chain link fencing, with gates for vehicle and pedestrian access
  • Ground upgrades to support the crane and other heavy equipment. This includes removal of existing asphalt, temporary removal of gravel, placement of geotextile grid or fabric replacement, placement, compaction and grading of gravel
  • Placement of mobile construction trailers and storages that will tie into existing power and communications
  • The laydown yard will consist of office trailer, lunchroom, car wash, storage and other ancillary facilities to support construction activities
  • Approximately 100 parking stalls (approximately 50 stalls for Site 1, 80 for Site 2) for on-site and off-site workers
  • Construction of a temporary trestle dock, including the installation of close to 60-70 piles ranging between 600-mm to 900-mm in diameter 
  • Installation of temporary mobile small boat dock made up of three flexi-float barges and a 23.5-m x 1.2-m (77-ft x 4-ft) engineered gangway
300 tonne (Liebherr LR 1300 or equivalent) crawler crane, dimensions 8.2 m x 20.4 m x 5.0 m (27 feet x 67 feet x 16.5 feet) with max boom to tip height of 73.2 m (240 feet)
100 tonne rough terrain crane (Tadano GR1000XL or equivalent), dimensions: 3.4 m x 14.3 m x 3.8 m (11 feet x 47 feet x 12.5 feet) with max boom tip height of 45.7 m (150 feet)


Pile driving

  • Pile installation will occur during daytime hours within the least-risk biological window (August to March) to mitigate impacts to fish and fish
  • habitat; subject to VFPA permit approval, this is scheduled for early 2018.
  • Pipe piles will be installed as far as possible via vibratory method. Where necessary the installation will be finished using a diesel impact hammer during daytime hours only.
  • Underwater noise and pressure will be monitored and mitigated with methods such as bubble curtains to limit noise travel underwater beyond the active construction area

Site Operations Activity

Land-based Activity

Material expected to be handled and stored in the yard includes: steel pipe pile, steel sheet piles, steel beams, rebar, forms, lumber, beams, nuts and bolts, pipe modules, anchors, buoys, wire rope, skip boxes, piping spools, electrical components and insulation.

Cranes will be stationed on-site to load/off-load material from barges and road legal trucks in the laydown areas. Additional material handling equipment, such as forklifts and wheeled loaders will be on-site during the operational stage of the Project. 

Marine Activity

All marine activities will be managed safely and in accordance with VFPA rules and guidance as published in the Port of Vancouver, Port Information Guide.[1] KLTP anticipates up to two barges being moored at site at any time and for barges to be brought to the site or hauled away from the site approximately once per day. All barge moves will be controlled by tug boats with certified personnel.

Water taxis will transport 50 to 60 workers daily to the Westridge Marine Terminal, located approximately 5 km east of the Second Narrows Bridge. This will require two to three water taxis, each making one trip at the start and end of each shift. One of the water taxi vessels will carry approximately 40 passengers and will measure 10.7 m long x 4.8 m wide. The other one to two water taxi vessels will carry 12 passengers and will measure 8.8 m long x 3.4 m wide. A water taxi will be on-call throughout the shift providing site access to supervisors, inspectors and other personnel.

Hours of Work and Traffic

The construction work associated with site setup will be conducted within VFPA’s standard construction hours of Monday to Saturday between the hours of 7 a.m. and 8 p.m.. If any work is required outside of these hours, KLTP will submit a Request for Amendment to the VFPA.

KLTP’s goal is to maintain safe work environments and minimize any traffic disruptions.

As is the case for all temporary sites that support the Project, traffic noise is not anticipated to be significant. Once operational:

  • Truck traffic to and from construction yards will have a moderate impact on public roadways, with most traffic occurring in the morning (7 a.m. to 9 a.m.) and in the evening (5:30 p.m. to 7:30 p.m.)
  • Approximately 130 light duty and other worker vehicles will access the site each day during the operations period. These vehicles will mainly arrive at the site between 6 a.m. and 7 a.m. and leave the site between 3:30 p.m. and 6 p.m., Monday through Friday.
  • The site will also be operational on Saturdays; approximately 40 vehicles per day are anticipated, arriving and leaving at similar times as during the work week
  • Materials will be delivered to and hauled from the site on road-legal trucks. KLTP anticipates up to 10 trucks per day will access the site
  • The use of water taxi for workers, as well as short driving distances to and from this site, will help reduce overall traffic effects on the adjacent road network
  • Buses will be also used to transport workers to Westridge Marine Terminal and other KLTP construction sites for TMEP. This will require one to two buses, each making one trip at the start and end of each shift   

Lighting 

  • Detailed site lighting plan has been prepared by a qualified lighting professional 
  • Installation of 10 temporary 470 watt area lights on the existing wooden poles along the site perimeter
  • LED Fixtures will be installed at 9 m (30 ft.) and orientated to 90 degrees facing away from surrounding community. The optics within the LED fixture focuses the light to 180 degrees which diminishes the effects of backlighting
  • Installed to improve safety and security on the site, without creating nuisance lighting for the neighbouring community or marine vessels 
  • Co-ordinated with BC Hydro, necessary approvals and permits will be obtained


Regulatory Requirements

The VFPA has jurisdiction over the entire site and will review the Project Permit applications for Site 1 and Site 2, as per the Port Authority’s guidelines. A Construction Environmental Management Plan (CEMP), Traffic Management Plans and other management plans will be required by VFPA to ensure necessary measures are employed to minimize disruption to neighbours. The CEMP has supporting reports, such as a Storm Water Pollution Prevention Plan, a Spill Prevention and Emergency Response Plan, Terrestrial and Aquatic Bio-physical Survey Reports and Soil Management Plan.

In addition, construction of the Trans Mountain Expansion Project is subject to 157 conditions from the National Energy Board (NEB) and 37 from the BC Environmental Assessment Office (BCEAO). These conditions apply during various stages of the Project’s life cycle, including before construction, during construction and during operation. Conditions are developed to reduce possible risks and to ensure TMEP is planned, built and operated safely. Trans Mountain has been seeking stakeholder feedback in a number of areas, including:

  • Environmental and socio-economic assessment for temporary construction lands and infrastructure (Condition 60)
  • Environmental protection plan (Condition 78)
  • Traffic control plans for public roadways (Condition 73)

Next Steps

KLTP must undergo a Project and Environmental Review of the Commissioner Street sites. Site 2 is a Category B permit that was approved by the VFPA in August 2017. Site 1 is a Category C permit that requires up to 120 business days for VFPA review. This includes a public comment period between September 27 and October 25, 2017 providing opportunities for stakeholder and public comment.

Feedback on the use of this site closed on Oct 25, 2017. If you have any questions please contact 1.866.514.6700 or [email protected].
