PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: The current fiber-optic system is poorly designed and not user friendly. Outside and across Cub Creek are “the Rocks” which is where the fiber-optic terminal boxes are located and where the distance learning cart can be plugged in and operated from. Unfortunately, their use requires the junction box to be re-wired for each location rendering that impractical for setting up and moving the cart. Replacing this system to a more user-friendly interface will make using the distance learning cart a simple plug and play system. More lessons will be taught outside in the areas related to the lessons, making it easier to connect to the subject matter. The light bollards are outdated, and parts are no-longer available. The fixtures use CFL bulbs which are somewhat inefficient and push the system past its operating capacity into "safety shutdown" mode. Replacement of this system with stand-alone self-contained lighting units will eliminate the solar panel/battery storage units as well as eliminating underground wiring and provide a cleaner more "night sky friendly" lighting system.

1.2 Work Covered by the Contract Documents:

A. Project Location: 8523 West State HWY 4 Beatrice, Nebraska, 68310

B. Fiber-optic work consists of: This portion of the project consists of adding a new Fiber Optical enclosure panel at the Freeman school and rerouting the existing fiber into the new box. It also requires Fiber Optical and electrical work in the “Rocks” at the Education Center. The “Rocks” are a durable plastic covering that protects in-ground junction boxes that contain Fiber Optic and electrical service to four locations around the property. See map and photos in the photo section of this spec. Each in-ground box is approximately 20”x30”x11” deep. Each “Rock” is approximately 18” high. These “Rock” looking covers must remain and all work to be performed must fit within each cover after complete. There are four “Rock” locations. This specification will refer to each location as Rock #1, Rock #2, Rock #3 or Rock #4. Work to be performed under this portion of the project shall be as follows:

1) Re-splice, terminate, test and supply report of test results for the existing Single Mode fiber optic Cabling at each Rock location.

2) Rock # 1, 2, and 4, Supply and Replace the existing Fiber Optical Enclosures and SC -Adapter Panel for Single Mode 6-Fibers. Provide enclosures that will fit inside the Rock covers and allow the cover to close properly.

3) Rock #3 - Relocate the fiber and 120VAC power from Rock #3 to the nearby Wayside exhibit. See attached photo for conduit pathway. Hand dig the trench and provide all necessary connections and conduit to meet all local electrical codes.

a. This will include contractor supplying and mounting a NEMA 4x Enclosure on the back side of the Wayside Exhibit. (Enclosure must fit within the 36”x36” area between the legs of the Wayside Exhibit. The Enclosure can be
