PROJECT SPOTLIGHT
A total of 5,600 piles were installed (~350,000 linear feet),
ranging from 18-inches by 40-feet to 18-inches by 60-feet.
“Our team utilized company-owned cranes on this project,
utilizing five driving rigs at its peak,” he said. “Cranes ranged from
Kobelco CK1000s, CK1100s and CK1600s equipped with fixed
leads. We also utilized company owned APE D30-52 Hammers
with APE leads.”
The project consisted of pile installation in four separate areas
within the large greenfield site. The four working areas consisted of
compression, static and lateral load testing.
“The pile dynamic analysis was completed on five percent
of production piles installed, and PDA testing was performed
on all test and reaction piles installed. We also performed excavation
and haul off for bathtub locations removing 34,000 cubic
yards of spoils from the site, pile cut off and removal, predrilling
and pile punching.”
Challenges
The GROUP team is very proud of its impressive safety record on
this project, with zero recordable incidents. However, this did not
mean this massive project was without its challenges.
“Ground conditions were extremely hard and refusal of piles
over 50 feet were inevitable in most areas,” said Thompson. “This
resulted in an obstacle course of driving conditions not only for constructability
– but safety. Working with the client, our field staff
and management staff, this project was executed ahead of schedule
and without incident. A big reason this project was completed so
quickly was due to schedules that ranged from 4/10s to 13 days on
and one day off.”
GROUP Deep Foundations worked with several other companies
on this project that included: Texas Concrete Partners (pile
supplier); Aggregate Technologies, Inc. (pile cut off); and Tolunay-
Wong Engineers (third-party testing and pile logging.)
