New Digs: New Jersey Contractor Uses Fresh Approach for Driving Piles

This article provides information about the growing use of Global Positioning System (GPS) for construction projects. As an example, the author describes a project in New Jersey requiring the replacement of a 70-year-old causeway. The contractor uses GPS mounted to a drilling rig to carry out VCIPC, or vibra cast-in-place columns. The GPS system includes unique computer software enabling the operator to see in real time the penetrator-point positioning data. Advantages in using GPS include cost and time: usually three or more stakes are placed around the penetration spot to act as a guide for the drilling-rig operator. The article also includes brief descriptions of VCIPC as well as the cost benefits of GPS technology.
