Oil Tank Farm Foundations

PROJECT DETAILS

Project Name:	Galveston TX Oil Tank Farm Powersystem Foundations
Installation Criteria:	4.5″ pressure grouted HD Micropile 25ft & 5.5″ Pressure grouted HD Micropile 55ft
Project Lead:	Tim Johnston
Equipment:	Cat 349 with a HD150 & Komatsu 490 with APE HD70 top drive
Installation Depths:	25ft and 55ft
Jobsite Restrictions:	Superfund site. Piles cannot create a pathway between contamination and clean water aquifirs. Tower loading – tension and compression
Geotechnical Concerns:	High ground water, clay rich soils
Pileworks supplied:	Tools, helical pile material, and engineering and testing support
Time to Install single unit:	8-15 min 25ft 4.5″ Pressure Grouted pile 25 min 55ft 5.5″ pressure grouted pile
Pileworks job influence:	We provided client with our new thread-on pile cap for this project and directed load testing & design.


Description:	The EPA controlled the process of pile selection, the process for pile approval was stalling the job. The pressure-grouted micropile solution gave the EPA the pile they needed to protect the clean water aquifers from the contaminated soils above. Approval of the grouted displacement pile moved the project forward. Pileworks provided engineering and load testing support to complete the design of towers and cable tray racks. We also used our new thread-on pile cap to eliminate on-site welding from the pile process.
