RCAG Tower Replacement Project

Horton, Oregon

December 2020

Introduction: The FAA is planning to select a contractor for Horton telecommunication tower replacement project including demolition of existing towers, and design, manufacture and installation of new RCAG towers at two FAA QXW & QXWA facilities located at Horton, Oregon.

Project Description: The QXW RCAG facility will have two (2) new 40ft Self Standing towers installed. The QXWA RCAG facility will also consist of two (2) new 40ft Self Standing towers installed. The towers will be supported by concrete foundations, type TBD based on the soil conditions. Telecommunication equipment and electronic cables are mounted on the tower platform as detailed in construction drawings and project specification. The towers also consist of lightning protection system to be connected to the existing grounding system. The existing

QXW site consists of three existing 40ft guy-wire towers located at a plot approximately 200’ x

100’ and QXWA site consists of two 40ft and two 60ft existing guy-wire towers at a plot approximately 100’ x 100’. The sites are located at Horton, OR, and are max. 0.3miles far away.

The project includes design, procurement and installation of new towers and associated platform, design/construction of foundations, procurement/installation of electronic cables, lightning protection system, prefabricated manholes, enclosures, conduits and associated material, hardware and connectors as required. The project also includes all construction activities required to complete the project per specifications and construction drawings. All existing guy – wire towers as well as one decommissioned telco tower (at QXW site) to be demolished and the material to be recycled or disposed per this project.

The existing site plans of QXW and QXWA sites are shown in appendix A & B. The proposed locations of the towers is shown in construction drawings attached to this document.

Local district System Support Center (SSC) will provide the necessary escort to the sites.

Note: The procurement and installation of electronic cables from tower junction box to communication antennas and from building junction box to radio racks inside the building, as well as procurement and installation of communication antennas are excluded from this scope of work.
