Brice was contracted to demolish existing towers and design and install two new 30-foot self-standing antenna towers at the FAA GSN Facility located at Saipan Obyan, CQ, Northern Mariana Islands. Brice demolished and recycled two existing self-standing towers including the foundation, antennas, conduits, antenna mounts, grounding, cable enclosures, coaxial cables, and lightning protection materials. We constructed 14’x14’x5’ pier style tower concrete foundations. We procured two new 30-foot self-supporting antenna towers which were delivered to the site via commercial barge. Brice provided the complete tower including anchor bolts, safety ladder, safety climbing devices, anti-climbing device/tower ladder door, eight fully operational/retractable swing-arm antenna mounts, two air terminal support masts, lockable access hatches and all essential hardware. The towers were hot dipped galvanized and coated, including the fasteners to minimize premature corrosion.
We also installed one electronic enclosure with supports on each tower platform. We installed electronic coaxial cables and connectors to the J-box, supports on the tower, and coaxial cable shield ground kits on each antenna tower. We supplied and installed conduits for the coaxial cables with elbows, clamps, supports, and connections. As part of the conduit installation, we excavated trenches from the new towers to the existing manhole and backfilled trenches once installation was complete and inspected. Brice installed electrical grounding and lightning protection at each tower. This included excavating and backfilling perimeter trenches around the new towers.
Brice bonded the new antenna tower electrical energetic system, provided air terminals and down conductors, and provided electrical ground bonds to the ladders, antenna cable enclosures, structural steel, antenna mounts, and coaxial cable shields. We also provided conductors/conduits to bond down conductors and antenna cable enclosures. Once installation was complete, Brice conducted earth resistance tests of the new EES system and provided written test reports to the FAA.
