This project consisted of the removal of four guyed towers and the installation of a new, eighty foot tall, self-supporting tower and a new RLPA with a rotator and mast. After conducting calculations, gas-powered metal saws and telescopic all-terrain fork lift were used to remove the four guyed towers. The decommissioned towers, between 60 and 80 feet in height, were cut and removed from the site, and the old foundation was removed by a local excavating company.
Next, the new antenna, tower, and transmissions lines were delivered to the site via contractors and rental equipment. A local contractor also prepared the new foundation for the new RLPA tower, while the rebar cage was delivered and constructed by a local supplier. The antenna was assembled on the ground, while the tower sections were assembled with a forklift. Next, the tower, rotator, mast and antenna were erected with a 70 ton crane, and the transmission and power lines were trenched in conduit from tower to the existing communications room. The transmission lines were pulled by hand.
The excavation, rebar and concrete were inspected and tested by a geotechnical engineering company. The transmission line and antenna were pressure tested. The entire system was tested to ensure it met the manufacturer’s standards, requirements, and specifications. From start to finish, the project took four weeks.
