Kennedy Space Center
Situation: Florida Foundation Repair of Jacksonville, FL was contacted to support
the proposed vibration table that is being constructed as a testing apparatus
at the Kennedy Space Center’s Cryogenics Testing Lab. This impressive
testing device will rigorously test various shuttle components, including
cryogenic components, low-temperature applications and propellant servicing
systems. The engineered design required the foundation to support the
60,000 lb dead load of the equipment and the anticipated 515 psf live
load created by the vibration table while in use; however, the proposed
reinforced 8” slab and soil conditions could not handle the load
requirements alone. Any displacement of soils could prove to compromise
overall testing results.
Solution: With an ultimate capacity of 50 kips and working/allowable capacity of
25 kips, Rush Construction requested that Ram Jack provide a solution
to meet load requirements. (9) Ram Jack 2-7/8” Helical pilings with
a 10”-12” helix configuration and new construction pile caps
were installed at the Cryogenics Testing Lab.
Conclusion: Preventative helical pilings with new construction pile caps installed
to support the vibration table’s foundation will ensure stabilization
of the sensitive testing equipment. Ram Jack’s minimally invasive
and quick installation helped the progression of the project, and allowed
Rush Construction to stay on schedule.
