GREAT CANADIAN PROJECTS
plant, three 20-foot sea cans of equipment, 11 48-foot trailers
of casing and 30 20-foot sea cans of hollow bar material had
to be shipped from various locations in Europe and North
America by sea and arrive in time to avoid delays throughout
the duration of the project. Space on the site was also limited
so the timing of these deliveries was critical.
A rigorous testing and quality control program was also
developed to ensure the success of the project. Due to the
size and capacity of piles required, a testing program was
established to test the grout to soil bond in four- to six-metre
horizons to reduce test loads. A composite grout to soil bond
was calculated to determine the required pile length.
Fourteen verification tests were completed at 250 per
cent design load to validate the design assumptions. Sixteen
additional piles were proof tested throughout the duration
of the project.
Brewster Drilling and Piling employed the use of an automated
cement batching system with a 60,000-pound silo to
ensure grout quality and also to allow for quick water cement
ratio changes during drilling and completion.
“We completed piling installation in early March
2019,” said Fetterly. “The project was completed in phases
as portions of the site were made available. A total of
90 working days to complete the piling, including pre-
production testing.”
As a result of the efforts of Brewster Drilling and Piling,
and the equipment and skilled workers deployed on the project,
the job was completed two weeks ahead of schedule with
no downtime on critical path equipment.
The entire BELCO North Power Station project is scheduled
for completion in early 2020.
