Woodbridge Energy Project, New Jersey
The Woodbridge Energy Project was a created to help supply energy to the NY/NY metro area to meet the growing demand for power while also increasing the reliability of the local electrical grid. Underground Devices provided custom designed and manufactured bore spacers to support the conduits in the horizontal directional drilled (HDD) casings. These HDD installations crossed underneath two environmentally sensitive wetland areas. Each HDD was approximately 2,000 linear feet.
O’Hare Modernization Program, Chicago, IL
The O’Hare Modernization Program was a broad effort to reconfigure the old airfield into a new more efficient runway, taxiway, terminal, and roadway system, reducing delays and increasing capacity to meet future aviation needs. In this photo, Underground Devices, Inc., Wunpeece Spacers were used to install a large duct bank of 5” power conduits adjacent to a new runway.
UPS Hub 2000 Project, Louisville, KY
The UPS Hub 2000 project was a $1.1 billion project that doubled the size of UPS’s package sorting operation at its hub in Louisville, KY. The project contains a large utility corridor in which Underground Devices Multi-Mount Cable Support Arms were utilized to support the vast network of power cables installed to support this major upgrade. The photo featured for this project is a recent photo, showing what the installation looks like 20 years after installation.
