Wright Brothers National Memorial (WRBR)
Fiber optic cabling and raceway installation

This project is for the installation of underground fiber optic infrastructure between buildings to
create a campus environment. This project will connect the Wright Brothers National Memorial
(WRBR) Visitor Center network room to network cabinets inside both the large and small fee
booths and to the network cabinet in the office trailer. The project includes all labor, supplies,
materials, and testing necessary to create a fully functional fiber optic network between these
four buildings. It is the responsibility of the contractor to provide a fully functioning network
infrastructure from end to end (fiber optic patch panel to fiber optic patch panel) for each
building within the campus. Acceptance of the completed work will be based on an acceptable
Bi-Directional OTDR test that falls within the specified limits. This scope of work describes the
minimum level of performance required by the government. All equipment must be new and
unused. *Connecting non-government devices to the government data network is strictly
prohibited! All technicians performing work must be certified to install and terminate fiber. All
work shall be done in accordance with the attached National Park Service Cabling Standards for
all data network cabling specifications and installation requirements. The Wright Brothers
Visitor Center is a National Historic Site.
