 Our Experience

Since the early 1960s, the Graycliff Federal leadership team has plowed and trenched thousands of miles of copper cables. In addition, we have successfully completed numerous aerial cable plant and manhole/duct bank system installations. We were among the first in the United States to bury long-haul fiber optic cable, and have installed hundreds of thousands of feet of inside voice, data and video cable.
Many of our projects have involved working in High Security areas for both commercial and military clients, within as well as outside the borders of the United States. We are familiar with all DOD security requirements and maintain rigorous internal screening procedures to ensure the highest levels of security.
Some of our more significant projects have included:
