While the inner workings of ShapeArray are fairly complex,
the system itself is pretty user-friendly. Measurand and Monir
technicians worked closely on preparing for this installation
and Measurand provided some preliminary training and was

on site at various times during the project. The ShapeArray
was so significant to the monitoring that part of Monir’s risk
management was to have the technical support of Measurand
ready and available if needed at any point during significant
activities on site.
“I think it worked exactly as we hoped it would,” Ford said,
adding the system has proven to be extremely durable. “We
did have redundant monitoring in place including inclinometer
casings installed very close to the sensor location so if
there were any malfunction with the instrument, if a cable
was damaged or there was a question about any movement
we saw from the sensor, we could confirm it. Our monitoring
programs always provide for redundancy; in construction it’s
too risky to rely on only one instrument.”
Robert Praeg, a geotechnical instrumentation specialist
with Measurand, says the company is proud to be involved in
such a high-profile project.
“ShapeArray has been used in some of the most highprofile
projects all over the world. It’s always nice to get a
chance to add to that portfolio of projects, especially with a
project so close to home with The One. It’s not every day that
the largest skyscraper in Canada is built on one of the busiest
streets in one of the busiest cities in the country,” he said.
Construction on The One began during the summer of
2017 with Clark Management serving as construction managers
for the project. Most of the underground work on the
project is expected to wrap up early this year with aboveground
construction scheduled to start later this year and
continue through to 2023.
