...heavy cranes transferred the
rocks to the exact locations,
literally moving them into place
with millimetre accuracy.

TECHNOLOGY
Closely coupled with the art was the
technology that is essential to converting
each vision into reality. Using 3D
scanning technology, we documented
the physical model to generate a
computer 3D model, which allowed us
to accurately calculate the volume and
weight of the granite required for the
job. With this data, other consultants
could assess the required geotechnical
foundations the site could manage, and
assess the costs of the decisions we
needed to make as the design unfolded.
By developing sections through the
CAD model, we could study various
construction opportunities more
efficiently than with the physical model.
We could be more flexible in the sizes
of stone and the joint tolerances, which
kept the project competitive from a
tendering point of view. The mass and
void could be achieved with either a few
30-tonne stones or with a larger number
of 3-5 tonne rocks. As well, LANDinc
could more easily realize its vision at the
quarry. We could make certain that the
end creation could be assembled into
a bluff in a natural yet sculptural and
playful manner.

A BLUFF TO EXPERIENCE
The approach led to success in finding
an appropriate rock face at B.O.R.
Aggregates, where we worked with
Aldershot Landscape Contractors
and HGH Granite experts to achieve
the character we were seeking and
to create an efficient selection and
building process.
Within a month, Walter Kehm, and
the team brought life to the vision
that would create new recreational
and aesthetic benchmarks along the
Toronto Waterfront. The flexibility in
the process became a major asset
as they realized new opportunities
on the quarry site. One of these
opportunities, the human imperative,
revealed itself to Walter and I as we
witnessed a young child at the quarry
discover a natural carved stone that
was perfect for a seat. New criteria
were introduced that day.

The wall is built to human scale. "The
ability for people to sit, climb, find
retreat areas in caves, find overlooks and
perches...all were carefully integrated
into a visually exciting composition,"
said Walter Kehm. With the images and
models in hand, he stressed the careful
coordination of "the varying colours,
forms, seams and geometries to form a
unified composition."
RAISING THE WALL
Urbacon, the project's construction
manager, and Infrastructure Ontario
accepted the project's unusual
approach, and the entire bluff wall was
constructed on the floor of the quarry,
then de-constructed to be transported
to Toronto in over 80 tractor-trailer
trucks. Every stone was numbered, a
photomontage created to show exact
locations and elevations. An on-site
survey using a GPS system marked each
stone's corners and key features. This
layout was transferred to the Toronto
site, GPS points marked by painted nails
hammered into the ground. When the
stones arrived, heavy cranes transferred
the rocks to the exact locations,
literally moving them into place with
millimetre accuracy. The entire bluff was
reconstructed in six weeks.
