“Monitoring during excavation and construction is
like an insurance policy”
“Typically, the requirements for supportive excavations
and shoring are found in urban locations where you have
nearby buildings and are planning a deep excavation, so
our main markets are Toronto, Ottawa and Calgary, and
mostly urban projects, but not exclusively,” said Rob Mara,
RWH’s quality assurance manager. “In our own markets we
provide construction services for competitors such as vibra-tion
monitoring, inclinometers, constructability and quality
control,” Mara said. “We occasionally work with other con-tractors,
but more so with developers. We’ll also work with
other consultants to look at value engineering on projects
such as construction suitability and optimization of founda-tion
solutions.”
Owners are becoming more aware of the risks of exca-vating
next to existing buildings in urban settings and
monitoring during excavation and construction is like an
insurance policy, said Rowe, “a tool that owners can use to
protect against litigation or to minimize their risk – when
there are problems with adjacent buildings we can say,
‘Review the monitoring data: the building didn’t really move,’
or within a reasonable amount of what you’d expect.”
“Different areas throughout Alberta and Ontario some-times
have incredibly specific ground conditions,” said Mara.
“Understanding how the ground is going to behave requires

unpredictable – when you
excavate it’s really tough
to know how much these
walls are going to move.”

experience and insight, as well as the technical understand-ing
of the theories that apply.”
RWH in conjunction with HCM continues to work on
many unique projects across Canada. Recently, these have
included the excavation for a new hotel in Ottawa using a
curved lagging wall to accommodate the parking structure
and a 40-metre-diameter shaft in Hamilton with perched
piles and shotcrete rock protection, which will extend 90 feet
deep when completed later this year.
