A.H. Beck install 111 drilled shafts into rock formations within Comerio, Puerto Rico.
Overview:
This project consisted of 111 drilled shafts up to 96’’ diameter with depths between 20 and 85 feet. The shafts were drilled into rock formations with a hardness ranging from 8,000 to 27,000 psi and RQD’s of 30% up to 100%. Due to the extremely hard rock formations, A. H. Beck utilized specialty tools including a 48” down hole hammer to penetrate the rock. This project had many unique challenges including environmental restrictions, flooding during the rainy season and the effects of the hurricane season.
