BRIDGING THE GAP
The Deh Cho Bridge connects NWT
residents to the rest of Canada

Why I chose this article:
Aside from providing a beautiful cover shot for Issue 1 2013,
this article is a very interesting read. The construction of the
Deh Cho Bridge, the first bridge to cross the Mackenzie River
(Canada’s longest), cost $202 million and finally connected
communities in the North Slave region of Canada (including
Yellowknife) to the rest of Canada. The bridge allowed those
people access to necessary supplies during winter freeze-up
and spring break-up on the river; previously, the only means
to access this region was by air. With a project so far north
in a rural, limited access site and extreme temperatures, this
is a project you need to read about. The Failure-Mechanism-
Concept for the bridge design is worth the revisit.
PILING CANADA CELEBRATES 10 YEARS
BOW POSED UNIQUE CHALLENGES
Calgary’s newest office tower is one of the most
innovatively designed buildings in North America

Why I chose this article:
As I started at Lester in July 2011, this issue was my first introduction
to Piling Canada. The Bow building in downtown
Calgary is a beautiful structure, and its crescent shape presented
certain challenges to crews. The project partners were
able to come up with innovative solutions, like the gigantic
raft slab foundation, which was reinforced with several layers
of rebar and weighed 33,000 metric tonnes. At construction,
it was the third largest continuously poured building foundation
in the world and cost $10 million. The meticulous
planning and interesting design of the structure make this
article a very worthwhile read.
