Edmonton's Valley Line Southeast LRT delayed again after inspectors discover cracks in piers

Edmonton's $1.8-billion Valley Line Southeast LRT will not openby the end of the summer as previously planned after inspectorsfoundcracks in concrete piers, the construction company in charge of the projectannouncedWednesday.

Ronald Joncas, CEO of TransEd, said inspectors noticed the issue on July 16.

"We have recently discovered cracks on some of the concrete piers that support the elevated tracks," Joncastold media at a news conference.

Joncas said of the 45piers along the route, 18 piers may require repair.

The cracks are due to thermal expansion issuesrelated to the weather, he said.

Crews have put up scaffolding around the piers and are undertaking strengthening measures, he said, and engineering teams are assessing all of the piers to try and better understand the root cause.

Joncas would not say how long the new measures will take and when the line might open.

"We are not in a position to give a date, because we don't know exactly what needs to be done," he said.

He said the company will have a better understanding of timelines in two weeks.

• Valley Line LRT to Mill Woods delayed 6 months, documents say

"This project has encountered unprecedented challenges," Joncas said.

Last October, the company announced that the project was delayed because of a longer-than-expected testing process for the new trains. COVID-19 also led to workforce shortages andsupply chain issues for some construction supplies.

In 2018, crews hit a concrete mass nine metres below the surface of the North Saskatchewan River during the Tawatin Bridge construction.

The latest delay means the line is nearly two years behind the original opening date of winter 2020.

Mayor disappointed

Mayor Amarjeet Sohi said as an advocate for accessible public transit, he's dismayed at news of the delay.

"It is frustrating and deeplydisappointing," Sohi said at a news conference Wednesday afternoon at Edmonton City Hall.

Sohi has been an advocate of the line since2008, when he put forward a motion for the city to embark on the project.

He acknowledged that the public has been eager for the line to openthis summer, as TransEd had been advertising.

"Many of us should have been able to take the LRT to Folk Fest last weekend," Sohi said. "I heard this time and time again from Edmontonians at the festival."

The Valley Line Southeast LRT has 11 stops, including one at the Muttart Conservatory at 98th Avenue, next to the site of the Edmonton Folk Fest at Gallagher Park.

Taxpayers not on the hook

City manager Andre Corbould said he's also frustrated and called the situation unacceptable.

"The delay is a significant inconvenience to passengers and people of Edmonton who should have been enjoying the Valley Line Southeast from Mill woods to downtown by now," he said.

"We are going to hold TransEd accountable to fix this problem."

Under the public-private partnership model, taxpayers are not on the hook for delays in the project, TransEd is, Corbould said.

"We expect TransEd to get this right and have the line open for safe, reliable service as soon as possible," he said.

'They are significant repairs'

Adam Laughlin, an engineerand manager of the city's integrated infrastructure services branch, saidthorough testingbefore opening the line to the public is important.

"That is why we go through that robust commissioning process to ensure that we capture any of those unforeseens, which do happen on large, civil infrastructure projects," he said.

There is no timeline on how long the assessment will take.

"From our perspective, they are significant repairs," he said. "So that's, at this point, the most that I can provide."

The city will continue to provide frequent bus service along the line.

Joncas said there is no safety risk to the public.

Crews will continue to finish the final testing work where possible.

"All inspections and tests will be completed and you will continue to see trains driving on the street-level track," he said.

TransEd has been testing the line since last summer, when it started running Bombardier light rail vehicles on the tracks at the Strathearn LRT stop on 95th Avenue.

Construction on the public-private partnership project started in 2016.
