Ram Jack Helicals Provide Housing Unit Stabilization Case Studies
Ram Jack Provides Stabilization to North Central
The North Central Choice Neighborhoods, part of the U.S. Department of
Housing and Urban Development (HUD), received a grant for a new development
in Philadelphia, PA, to provide mixed-income rental and homeownership
housing units. In the development location stood a group of building lots
that contained large amounts of fill materials and debris.
The debris from old homes that had been torn down several years before
plagued the lots. Although some debris could be removed, fill materials
could compromise future structural foundations.
The team at Ram Jack was contacted to propose a solution. After analyzing
the building lot, the team quickly identified the need for new construction
helical piles to be installed. They would need 728 piles in total. Ram
Jack commissioned the assistance of Larsen Landis – structural engineering
experts in Philadelphia. Together, Ram Jack and Larsen Landis provided
two load tests in order to verify the
capacity. The team would possibly need to perform some pre-drilling in
certain areas before the helical pile installation could begin.
Ram Jack Tri-States needed to install new construction helical piles to
carry grade beams and column loads for new houses to be constructed upon.
The team went ahead with pre-drilling for certain sections when they encountered
old rubble stone foundations that stood in the way. A total of 728 piles
were used, with an average pile depth of 24 ft. The team required loads
of 40 kip (allowable) and 80 kip (ultimate). The Ram Jack team maintained
impressive productivity and dedication throughout the entire process from
start to finish. The team moved so swiftly that the workers on site found
it challenging to keep up with them. The concrete crew always battled
to keep up the pace. The job was successfully completed and was the result
of 100% union labor.
