Supporting New Foundations Case Studies
It’s rare that a large construction job doesn’t run into some
unplanned obstacles. While this may be the case, it doesn’t make
these obstacles any more welcome, and the last thing a builder or contractor
wants to do is spend more money while adding to the time it will take
to finish a job. The builders of the Perry Homes East End on the Bayou
Townhomes in Houston, Texas ran into one such problem early in the project.
Situation: While preparing to build a new community of 37 modern, beautiful townhouses,
Perry Homes’ contractors appropriately analyzed the soil of the
build site. What they found was unpredictable soil with over 30 borings
in just two acres of land. Perry Homes contacted Ram Jack Texas for help,
hoping to build the homes without having to install drilled concrete piers.
Proposed Solution: Using the foundation designs provided by Perry Homes, Ram Jack engineers
came up with a solution that incorporated helical piles into the foundation
as a deep foundation element. By using helical piles, the compression,
tension, and lateral loads exerted into the foundation system by the structure
was transferred into more stable soil deep within the ground. Helical
piles, considered an instant pile, can immediately bear loads after installation
which reduces construction time. Additionally, the capacity of each pile
can be independently field verified by monitoring the torque during installation.
This helps ensure the pile has penetrated a soil strong enough to support
the structural loads.
Outcome: With phase one of this ongoing project, each building needed 18 to 21 piles.
In total, more than 700 helical piles will be used to complete the project.
Perry Homes typically releases three townhouses for helical pile installation
at a time. In just one day, Ram Jack Texas installed 21 piles for a single
townhome. The helical piles were installed on all three townhouses in
three working days. The embedment depths of the helical piles averaged
35 ft. Due to the efficiency of the Ram Jack team, Perry Homes was able
to immediately place the concrete for the foundations for the East End
on the Bayou Townhomes project. After choosing Ram Jack Texas because
of its strong reputation and ability to work in even the poorest soil
conditions, Perry Homes was more than satisfied with the job and extremely
pleased with the extended warranty provided on the work.
