Malcolm Drilling was awarded the design build contract to install a foundation system for the Terremark Data Center in Santa Clara, CA. This facility was constructed within the existing footprint of a concrete tilt up building next to an operational data center. The roof of the concrete tilt up was removed and the walls were internally and externally braced during construction. To develop and support the pile design, Cone Penetration Tests (CPT’s) were performed within the building footprint. Due to the variable soils conditions, all CPT’s were conducted in a grid pattern to determine pile depth across the site. Once the test program was accepted, the production piles were installed using the machines on-board automatic monitoring system.
All OMEGA piles were installed using a Bauer BG-28 drill rig equipped with an 18-inch full displacement auger tool. Pile length savings of almost 15% were realized on this project.
