The Calgary International Airport contracted Doublestar Drilling to complete piling and shoring work for its overpass and terminal expansion, which involved challenging tasks like installing rock sockets in limited headroom. Doublestar successfully completed the work on budget and ahead of schedule, and was subsequently awarded additional expansion contracts worth over six times the original value. In total, Doublestar completed 1,400 piles and 35,000 square feet of shoring and concrete work on the airport projects.

1. The Calgary International Airport
contracted Doublestar Drilling to complete a
critical scope of standard piling and shoring work in its
overpass and terminal expansion.
During this work, Doublestar was called to solve challenges
such as completing 2-to-4 metre rock sockets in only 14 feet
of headroom. This was an unprecedented issue that no one in
Western Canada was equipped to handle. Doublestar rose to the
challenge through collaboration and innovation. The project was
completed on budget and ahead of schedule.
Doublestar demonstrated our expertise, and were awarded every additional contract for
the expansion, resulting in additional contracts valued at over six times the original work.
When we wrapped up the projects, we had completed 1,400 piles and 35,000 square
feet of shoring, pouring over 10,000 cubic metres of concrete, on time and on budget.
Doublestar relied on their in house expertise to develop a
proposal with a viable solutions to complete the variety of
challenging scopes of work. Equipment was sourced internationally
that assisted Doublestar to self-perform all scope of work including
shoring, Caissons, limited access piling, grouting and micropiles.

2. When Judah Hill on Highway 744 began to
erode and slip into the Peace River valley, Alberta
Transportation enlisted Doublestar Drilling to complete
all the drilled piles and anchor scopes of work.
With tight timelines and strict budget guidelines, DSD
began the construction of the tie-back wall. Using specialized
equipment, DSD successfully installed 216 double corrosion
protection anchors on the hillside, ranging from 100 to 200
feet deep.
The overwhelming success of Phase 1 resulted in Doublestar
Drilling receiving the contract for a second, larger phase of work.
Phase 2 included a technical assessment of the soil to determine
equipment selection. As a result of the tests, we sourced and
purchased a micropile drill to install over 280 anchors.
In the end, we had engineered and installed 43,000 lineal feet
of anchor systems totalling 498 anchors, pressure grouted
for a total of 600,000 kilograms of high strength concrete.

3. Before construction began on Roger’s Place, Edmonton’s
newest landmark, Doublestar Drilling was contracted to execute a
pile load test. The goal was to increase the end-bearing capacity of
the structure’s piles, thereby reducing client costs.
The magnitude of the job resulted in a strategic partnership between
Doublestar Drilling and Enerpac. Together, we designed and created a fully
automated system capable of completing record-breaking load tests with
great accuracy.
This new system also required the design and creation of a reactive test frame of six
interwoven beams, each measuring six feet by 50 feet and weighing 35,000 pounds,
to control the four 500-ton jacks.
The Roger’s Place load test ended up measuring an
impressive 14,000 kilonewtons, Canada’s largest load test
to date. It resulted in improved safety and accuracy for
the build.
This new technology has increased Doublestar Drilling’s
capacity, allowing us to take on Western Canada’s largest
load test requirements.
