Construction at Keewatinohk is primarily being undertaken
by three separate contractors, each of whom are
subcontracting piling work specific to their scope of the
project. The HVDC facilities are being overseen by a consortium
of Siemens Canada and Mortenson Construction. On
that part of the project, Graham Brothers was contracted to
supply and install APE HD helical piles.

SNC-Lavalin is responsible for construction of the 230-kV
AC switchyard; their subcontractor is Pacer, which is handling
driven piling and pile cap welding. The auxiliary buildings are
being constructed by PCL Constructors Ltd., who turned to
Agra Foundations Limited for deep cast-in-place piles, some
of which extend up to 22 metres below ground and require
double casing, splicing of cages over the holes and the construction
and installation of greases and poly wrapped
sono-tube.
Brian Frost, Manitoba Hydro’s converter
engineering and procurement
department manager, says crews at
Keewatinohk have been installing
about 40 to 60 piles per day through
the winter; heated shelters and pre-cast
beams allow them to work even in subzero
temperatures.
Frost says the project will require
about 5,000 piles to be set into the
ground at Keewatinohk this winter and
into the spring. Of these, about 2,800
are helical piles that are being installed
with a CAT 374 and HD 200 drive head,
two CAT 349E hydraulic excavators and
a Komatsu 490, each with a HD 80 drive
head for pre-boring operations.
About 2,000 driven steel piles are
being installed with a Junttan PM22
pile driving rig, with two Soilmec SR-30
hydraulic drilling rigs for pre-boring and
drilling. About 200 piles are being cast
in place; these have to be kept warm
under heated tarps until they have set.
Feels like home
Throughout this winter, about 35 workers
have been directly involved with
piling operations at Keewatinohk.
Workers on the project stay nearby
at the recently opened Keewatinohk
Lodge, which has the capacity to house
up to 600 people. The workforce will be
needed as construction ramps up on
the converter station.
The Keewatinohk Lodge is operated
by a joint venture of Fox Lake Cree
Nation and Sodexo, and includes private
bedrooms and washrooms, modern
amenities including cable television
PROJECT SPOTLIGHT
“When you’re setting these piles for the foundations, you’ve got to account
for the fact that the long-term settling will be uneven.”
– Brian Frost, Converter Engineering and Procurement Department Manager, Manitoba Hydro
