PWS – DTA & GROS Electrical Improvements 28 July 2022

1. INTRODUCTION:

1.1. Eielson AFB (EAFB) is adding modern threat emitters to the Joint Pacific Alaska Range Complex. Improvements and expansion of the power infrastructure in the Donnelley Training Area (DTA) and at the Gerstle River Operations Site (GROS) are needed to meet this need.

1.2. LOCATION. The DTA is a series of training lands in the vicinity of Fort Greely, AK. The DTA project location is to the Northeast of Allen Army Airfield (approximate GPS Coordinates, 64.01686299463779, -145.6835736225112). The GROS project location is near the Gerstle River and the Alaska Highway (approximate GPS Coordinates, 63.80294703618339, - 145.07427133179755). Access to Fort Greely is not required to reach the project sites.

2. PROJECT OBJECTIVES:

2.1. Contractor will design a power distribution network that will utilize the existing GVEA 25 kV line and provide the following electrical services: 500 kVA, 480 VAC, Delta at sites 1, and 2, 225 kVA, 480 VAC, Delta at site 3, and 50 kVA, 120/208 VAC, WYE at site 4.

2.3 Fiber Optic Cable. The contractor shall install 24 strands of buried fiber optic cable from the maintenance building located at C-201 to the breakout point located on the road. From the breakout point, install eight strands to north, south, and west operation points. See Figure 6.

Installed fiber will use the following specifications:

- Fiber will be installed inside appropriate conduit.

-Rigid Nonmetallic Conduit Schedule 40 conduit following roadway, and schedule 80 at any point that crosses a roadway.

-Buried a minimum of 3 feet, using drainage material such as sand or gravel.

-Capable of operation at temperatures of at least –40 degrees Fahrenheit.

-Conduit will be co-located with the buried high voltage power lines.

-60 foot maintenance loop at breakout point.

-Bends will be limited to a total of 180 degrees between pull points.

-Endpoints:

-Splice points will consist of a 4 port, 2/4 splice tray.

-60 foot maintenance loop at each endpoint.

-Cables will be terminated with SC connectors in a patch panel.

-patch panels will have exit ports to allow MIL SPEC connectors.

2.4 Transformers. Transformers will be installed on a concrete pad with an appropriately sized utility vault that meets UFC standards. Each transformer shall be co-located with a power drop.

Power drops for the 500 kVA and 50 kVA drops shall have one connection for 480 V and four 120V outdoor rated duplex outlets. The 225 kVA transformer requires a 480 VAC connection for a future facility.

2.5 Power lines. The existing power lines north of 45 APL road and along the Alaska Highway have a primary voltage of 25000 V. See Figures 1 and 8. The contractor will need to coordinate an easement with GVEA to reach military lands. The contractor shall clear brush and trees as required for power line installation. Power lines at the DTA sites are required to be buried due to proximity to the airfield and a nearby parachute drop zone. The design shall ensure that appropriate measures are taken to account for the arctic environment and voltage drop.

2.6 Delivery. Delivery and installation shall be completed by 15 October 2022 for the DTA site and 15 October 2023 for the GROS. It is understood that there is a significant delay in the production of transformers. The contractor shall propose a delivery and installation schedule for these assets if they exceed the desired completion date.
