Innovative Piling Solutions
Collaborative Science Research Building (CSRB),
University of Saskatchewan, Innovative Piling
Solutions
The University of Saskatchewan (U of S) needed a new
91,000-square-foot research facility with four stories above ground,
one storey below ground and a cutting-edge greenhouse on the roof.
The original design called for straight shaft and belled drilled concrete
pile foundation and a CFA secant wall for the 15 feet of soil
that needed to be retained for the basement excavation. The original
design contained 89 straight shaft piles in the basement for the
structural slab, 66 belled piles for the main bearing elements and
208 secant wall piles for the shoring. Due to ground conditions and
a short construction schedule, IPS felt it was too large of an installation
risk to try and install the drilled and ACIP piles. Thus, an
alternate pile design was conceived to offer not only cost savings,
but as was most important for this project, the schedule savings, as
the U of S needed to have the pile driving completed in less than
one month due to final exams schedules and no pile driving equipment
was to be run on site during this time. IPS was awarded the
contract for the installation of the driven pile and earth retention
alternates. IPS was able to provide both cost and time savings to the
owner by using driven piles versus alternative foundation and shoring
systems. The project was completed ahead of schedule, despite
losing 30 percent of available working hours due to adherence to
applicable bylaws.
ARC Terminal Dock Refurbishment, P&H
Construction Corporation
The ARC Terminal Dock Refurbishment Project consisted of the
restoration of the existing dock that was built in the early 1940s.
In this project, P&H Construction Corporation had to install a
combi-wall adjacent to the failing dock, which began using an APE
100 vibratory hammer. Due to varying soil conditions, P&H suggested
setting the pipe and sheet pile with the vibratory hammer
in the upper loose soil layers and driving to grade in the tighter
soils. This method also alleviated issues regarding movement of
the dock. One of the major challenges on this complicated project
was determining how to place the backfill under the dock in order
to ensure it was 100 percent bearing on underwater sand fill. In all,
it took two weeks and more than 10,000 cubic yards of underwater
