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The existing light bollards are outdated, and parts are no-longer available.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. Removal of the existing system and replacing it with energy efficient LED self-contained bollards (provided by the Park) will provide a more efficient system, reduce the amount of system to maintain and eliminate a wired system to a main solar panel and battery storage 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”

2.1 SYSTEM DESCRIPTION

The Government retains the option to sample and test aggregates and concrete to determine compliance with the specifications. Provide facilities and labor as may be necessary to assist the Government in procurement of representative test samples. Obtain samples of aggregates at the point of batching in accordance with ASTM D75/D75M. Sample concrete in accordance with ASTM C172/C172M. Determine slump and air content in accordance with ASTM C143/C143M and ASTM C231/C231M, respectively, when cylinders are molded. Prepare, cure, and transport compression test specimens in accordance with ASTM C31/C31M. Test compression test specimens in accordance with ASTM C39/C39M. Take samples for strength tests not less than once each shift in which concrete is produced from each strength of concrete required. Provide a minimum of five specimens from each sample; two to be tested at 28 days for acceptance, two will be tested at 7 days for information and one held in reserve.

2.1.1 Strength

Acceptance test results are the average strengths of two specimens tested at 28 days. The strength of the concrete is considered satisfactory so long as the average of two consecutive acceptance test results equal or exceed the specified compressive strength, and no individual acceptance test result falls below the specified compressive strength by more than 500 psi.

Test concrete for compressive strength at 7 and 28 days for each design mix and for every 100 cubic yards of concrete. Test two cylinders at 7 days; two cylinders at 28 days; and hold two cylinders in reserve (for a total of 6 cylinders). Conform test specimens to ASTM C31/C31M. Perform compressive strength testing conforming to ASTM C39/C39M.

2.1.2 Construction Tolerances

Apply a Class "C" finish to all surfaces except those specified to receive a Class "D" finish. Apply a Class "D" finish to all post-construction surfaces which will be permanently concealed. Surface requirements for the classes of finish required are as specified in ACI 117.

2.1.3 Concrete Mixture Proportions

Proportion PCC mixtures to meet the requirements of Table below. Do not use fly ash in the PCC mixture. Manufacture the PCC in accordance with ASTM C94, Standard Specification for Ready- Mixed Concrete.
