Hazenberg says in the spring of 2016, CN approached a
half-dozen or so firms requesting unique proposals for a
design-build solution to the slide issue that would mitigate the
risks to the railroad’s operations.
“There weren’t a lot of specifications beyond that,” he
said. “We felt we were successful on this job at the onset,
because we evaluated many different solutions that could be
employed. Then we worked with the client to optimize the
one that was best suited for this project in consideration of
costs, risks, environment, other stakeholders on the project,
schedule and safety.”
Hazenberg notes that despite numerous technical and
logistical challenges presented by the project, there were no
interruptions to train service during the five months it took to
complete construction.
“It was a good team success which started immediately
with very strong collaboration between the client and AGRA/
Nicholson,” he said.
Hazenberg says that prior to the project, the tracks atop the
120-metre long retaining wall had to be realigned regularly to
counteract the shifting earth. The slope movement began to
pick up in 2015, he says, and eventually reached a rate of three
to six millimetres per day, which required CN crews to have to
adjust the tracks almost weekly.
Unusual project
The beam and lagging retaining wall was built in 2008 to protect
the railway bed from the loss of ground downhill from it,
