No. 10 AWG control cable” include installing 5/c No. 10 and 12/c No. 10 AWG control cable, respectively. The Contractor shall provide sufficient cable to allow termination on the highest terminal block in the switchboard section that is farthest from the other end point of the cable.

10. The Bidding Schedule item “Furnishing and installing fiber optics” includes determining lengths, furnishing and installing the fiber optic distribution cable (FODC) and inner duct, terminating the FODC and connecting it to the transformer KV1A and the Contractor-furnished and installed patch panel inside the service building, performing all splicing and testing the completed installation.

a. Material: All fiber optic communication equipment shall be commercially manufactured off-the-shelf items.

(1) The FODC shall be Optical Cable Corporation’s DX012DWLS9KR (twelve (12) fiber, 62.5/125 multimode, riser rated, indoor/outdoor), or equivalent. All optical fibers for the FODC shall be compliant with or exceed the requirements of ISO/IEC 11801 OM1. The fibers shall have no factory splices in any continuous length. The end of each length of cable shall be sealed so no moisture can enter the cable.

(2) Furnish and install flexible inner duct for the FODC. Install FODC in inner duct where not in conduit. This includes, but is not limited to cable installed in cable trays, cable trench and under raised computer floor. Inner duct shall be corrugated (for maximum flexibility), orange, have a 3/4-inch inner diameter and have a preinstalled pull tape. Inner duct shall be UL listed and designed for riser applications per NEC article 770.182 and resistant to the spread of fire per UL 2024, Vertical-Tray Flame Test (Riser). Install couplers and connectors to attach inner duct to conduit and to neatly terminate the installation.

(3) MM-FODC Termination: In the building, fibers shall be spliced to ST-pigtails.

(4) Fiber Optic Patch Panel: In the control building, a 24-port patch panel, with

ST-pigtails (62.5/125 fiber) and splice trays, shall be provided and installed in the vertical switchboard section CHB4 by the Contractor. The patch panel shall be Amerifiber’s AFM2412RCC003 or equivalent.

b. Installation:

(1) Install FODC/Inner Duct: Install the FODC/inner duct from the transformer control cabinet patch panels, to the fiber patch panel in switchboard CHB4, according to SG T600. In the transformer patch panel, 50-feet of FODC shall be coiled (coiled inside the patch panel) before connecting to ST patch panel. In the service building, leave a 50-foot service loop before routing to the patch panel.

(2) Terminate Multimode Fiber: Splice to pigtails in the control board. All fibers shall be terminated and connected in order as specified in ANSI/TIA-598C-2005.

c. Fiber Optic Testing: Perform fiber optic testing in accordance with the following:

(1) Factory Tests of FODC: Factory test results shall be recorded and included in the packaging with the FODC.

(2) Pre-installation Field Tests of FODC: The Contractor shall test all fibers to insure the cable was not damaged during shipping. Notify the COR at least 14-days prior to all pre-installation field tests to enable Western observers to be present. The Contractor shall perform an optical time domain reflectometer (OTDR) attenuation test at 850 nm on each fiber. Pre-installation tests shall be compared to the factory test results. OTDR charts at 850 nm shall be provided showing launch conditions and all other parameters used in setup, plus time and date. These charts shall illustrate and quantify overall losses, length of fiber, and stress points on the fiber.

Review the traces carefully and explain unusual discontinuities in detail.

(3) Post-Installation Field Tests of FODC: The Contractor shall notify the COR at least

14-days prior to the post-installation field tests to enable Western observers to be present. Perform end-to-end tests (patch panel-to-patch panel) for each fiber after all termination has been completed and all patch panels have been returned to their permanent position. These tests shall include continuity and attenuation at 850 nm using an optical loss test set to verify continuity and to benchmark attenuation.

Negative losses (i.e., gains) will not be accepted as legitimate benchmark attenuation. If negative losses do occur, the specific fiber shall be retested.

(4) Any damage to the FODC shall be replaced by, and at the expense of, the

Contractor. The Contractor shall be responsible for making modifications required to repair damage, subject to the COR’s approval. These modifications may include, but not be limited to the replacement and reinstallation of the fiber cable.

(5) Instrument Calibration: All test equipment shall be calibrated with certification traceable to the National Institute of Standards and Technology relative to their intended use.

(6) Qualifications of Testing Personnel: The fiber optic tester shall have a minimum of one year testing and operations experience with the OTDR and optical loss test set used for tests required in this specification, and shall be able to use all necessary test equipment without reference to test equipment instruction books while performing the required tests specified herein.

d. Fiber Optic Communication Drawings and Data: All drawings and technical data required to be furnished by the Contractor shall be in English. The Drawings and data shall be complete and accurate in their content. Originals and all copies shall be legible.

Western shall have the right to require the Contractor to make any changes in the Drawings and data that may be necessary to show the equipment furnished conforms to the requirements of these specifications. The design and coordination of the fiber optic communication equipment shall be the responsibility of the Contractor and Western assumes no responsibility to approve or review drawings and data that are submitted.

Message from the Administrator

At Western, we show our commitment to safety every day through the actions we take, the training we offer and the work conditions we provide. We expect the same commitment to safety from each of our contractors who provide products or services to Western. In performing work for Western, all contractors must make the right decisions to ensure that the work environment is as safe as possible.

Our safety program is based on four points:

Safety procedures or common sense must be applied by each

Federal and contract employee. Safety should not be set aside to meet a project schedule or for personal convenience.

Employees and contractors must believe that they have the right and the responsibility to identify and take action to reduce, if not eliminate, hazardous work environments and hazardous work practices.

Managers and supervisors must lead by example and execute their responsibility to ensure each job is accomplished in a safe and healthy way.

Safety is a personal responsibility. Each individual makes the decision on what action to take to accomplish a task.

By integrating these principles into every task we take, together we can ensure Western is a safe place to work.
