Trans Mountain pipeline expansion now well underway

More than 2,000 workers now employed on pipeline twinning project, mostly at either end, in Burnaby and Edmonton

When Prime Minister Justin Trudeau tweeted in mid-July that the Trans Mountain expansion project “is going forward, and work is getting started this construction season,” a typical reply was “I’ll believe it when I see it.”

Given all the protests and legal and political setbacks it has suffered, that skepticism was understandable. But the $7.4 billion to $9.3 billion pipeline twinning project is now under construction.

Also going ahead is $150 million worth of investments in new vessels and bases by the Western Canada Marine Response Corp., which paused its expansion following a Federal Court of Appeal decision that quashed the original approval of the pipeline twinning project.

As of September 30, 2,200 workers had been hired, and are now working, mostly at either end of the pipeline, in Burnaby and Edmonton. Those numbers were originally expected to reach 3,000 by the end of this year.

“We’re definitely excited to see it get underway because it’s going to mean an awful lot of employment for British Columbians and Albertans,” said Patrick Campbell, Canadian pipeline director for the International Union of Operating Engineers.

Campbell’s union represents about 35 per cent of the workers on three of the pipeline segments or “spreads” in B.C. At peak construction, each spread will employ about 350 construction workers, tradespeople, truck drivers and labourers.

“I think every British Columbian who’s qualified to do this kind of work will be busy,” Campbell said. “These projects are nation-building in their scale because, I think, it will be reasonable to call upon other Canadians to augment the workforce.”

Security perimeters have been cast around some of the key construction areas, like the Burnaby tank farm and Westridge Marine Terminal. In the Lower Mainland, much of the work going on now is concentrated at the Westridge site, where barges, cranes, derricks and other heavy machinery are working to expand the existing terminal, which will have three berths for oil tankers. The work also involves extending the foreshore.

In B.C., some of the most intensive construction work will be done in Burnaby. There, in addition to the expansion of the Westridge terminal, 14 new oil storage tanks will be built at Trans Mountain’s tank farm on Burnaby Mountain, bringing the total number of tanks to 26.

The terminal and tank farm will be connected by pipeline. That section of pipeline will require boring a 2.6-kilometre tunnel through Burnaby Mountain. That work is expected to start sometime in 2020.

“The terminals are sort of the critical-path items,” said Trans Mountain Corp. media spokeswoman Ali Hounsell. “It will take the full three years to build Westridge Marine Terminal. And it will not take nearly that long to build a segment of pipe between X and Y in the middle of Alberta or through the Interior.”

Overcoming hurdles

Early construction work had started in 2018 but was halted for a year, after the Federal Court of Appeal quashed the order-in-council giving the project the green light. The Trudeau government was forced to address two issues — First Nations consultation and marine impacts from increased tanker traffic — before giving the project a second go-ahead in July. 

Worked resumed on August 22, Hounsell said. The 1,150-kilometre pipeline, running from Edmonton to Burnaby, will be constructed in nine spreads. Work has started on the first spread in and around Edmonton. British Columbians won’t see much pipe going into the ground in 2020, except in Burnaby.

About 60 per cent of the pipe has already been delivered.

Some of the pipe that will go into the ground first will be through horizontal drilling at stream and road crossings, which is done to avoid disruptions to traffic and fish habitat from trenching.

The Canadian government now owns the Trans Mountain pipeline and is responsible for its expansion. Trans Mountain Corp. has not yet provided an update on the expected capital costs.

Original estimates of the twinning project pegged its cost at $7.4 billion. The Office of the Parliamentary Budget Officer has estimated the delays in starting could push that to $9.3 billion.
