Project specifications should be developed for each project. They tell
the construction contractor what work is to be performed for each
project.

Standard specifications tell the contractor the quality control that is
to be used. The quality control should not vary for each project and the
standards do not require editing for each project.

Edit the list under each bid item to meet the project requirements. All
work to be accomplished in the project must be listed under the bid
items. If work is not listed, it will not be performed.

                continuous length. Each continuous length of cable shall
                be wound on a separate reel. The end of each length of
                cable shall be sealed so no moisture can enter the
                cable. The cable shall be wound onto the reel so it can
                be pulled off without binding, kinking, or other
                problems.

        2.  Furnish and install inner duct for the FODC. The FODC shall
            be installed in inner duct at any point where it is not in a
            conduit. This includes, but is not limited to cable
            installed in cable trays, cable trench and under raised
            computer floor. The inner duct shall be orange, plenum
            rated, have a 3/4-inch inner diameter and have a
            preinstalled pull tape. Install couplers and connectors to
            attach inner duct to conduit and to neatly terminate the
            installation.

        3.  Cable Termination: At Animas River Substation, fibers shall
            be terminated to factory assembled pre-connectorized
            pigtails that come in the existing fiber optic patch panel
            FOC1. The existing fiber optic patch panel (FOC1) is located
            in vertical switchboard section CHA1. See drawings ANM 4000
            and ANM 4001. At Durango Substation, the optical path will
            end with the OPGW on the take-off-structure (bare fiber).

        4.  Optical Splice Enclosure: The optical splice enclosure shall
            be AFL Telecommunications' Opti-Guard Splice Enclosure, or
            equivalent. Splice enclosure will be furnished with splice
            trays and predrilled end plates for the cable(s) and/or
            conduit entrance. The enclosure shall be provided with the
            two 24-splice splice trays and the appropriate types/numbers
            of cable/conduit connector kits to accept OPGW and/or 1 inch
            flex conduit. The Contractor shall seal any unused openings
            in the end plate with a manufacturer's approved sealing
            assembly.

    b.  Installation:

        1.  Install an optical splice enclosure at Animas River
            Substation (TOS) per drawings ANM 1115 and ANM 1901.

        2.  Install FODC from the optical splice enclosure on the TOS to
            the optical patch panel in the service building. The FODC
            shall be installed in inner duct at any point where it is
            not in a conduit. This includes, but is not limited to,
            cable installed in cable trench/trays and under raised
            access floors. FODC shall be routed through existing conduit
            from the TOS into the service building. The Contractor shall
            leave a 30 foot loop of spare FODC/innerduct under the
            raised access floor before routing to the vertical
            switchboard/patch panel for termination. At Durango
            Substation, no FODC will be installed. The optical path ends
            with the OPGW on the TOS.

        3.  Terminate the FODC by splicing to factory-installed pigtails
            in the patch panel, and by splicing it to the OPGW at the
            TOS.

        4.  Optical Fiber Splices: All fiber splices shall be fusion
            spliced and have mechanical protection for each splice. The
            maximum bidirectionally averaged splice loss shall be 0.15
            dB.

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

        1.  Factory Tests of FODC and OPGW:  Factory tests shall be
            performed on each fiber of every reel at the factory.
            Results shall be recorded and included in the packaging with
            the cables. Product data sheets showing the cable
            characteristics including dispersion, dimensional quality,
            and tensile strength shall be provided from the
            manufacturer.

        2.  Pre‑installation Field Tests of FODC and OPGW:  The
            Contractor shall test all fibers of each reel of FODC/OPGW
            upon delivery. Notify the COR at least 7 days prior to all
            pre-installation field tests to enable Western observers to
            be present. Contractor shall submit optical time domain
            reflectometer (OTDR) charts at both 1310 nm and 1550 nm
            showing launch conditions and all other parameters used in
            setup, plus time and date. A 1km launch fiber shall be used.
            These charts shall illustrate and quantify the losses of
            each length of fiber and stress points on the fiber. Review

            COR at least 7 days prior to the post‑installation field
            tests to enable Western observers to be present. Perform
            end‑to‑end tests for each fiber after all splices have been
            completed and all splice enclosures, except for those
            required for fiber access during testing, have been returned
            to their permanent position. These tests shall include:

            a.  OTDR charts at both 1310 nm and 1550 nm showing launch
                conditions and all other parameters used in setup, plus
                time and date. These charts shall illustrate and
                quantify the losses at each splice, length of fiber and
                stress points on the fiber. Review the traces carefully
                and explain unusual discontinuities in detail.
                Photographs of OTDR test results will not be accepted.
                OTDR measurements shall be made in both directions and
                the splice loss results bidirectionally averaged. When
                testing from Durango, a 1km launch fiber, spliced to the
                OPGW end-of-fiber, shall be used. **Bidirectional
                averaged values shall be clearly displayed in a separate
                chart that identifies each splice location by tower
                number and direction of measurement.** Bidirectionally

into action, they remain just words. We at Western believe that safety
is not just a piece of paper but integrated actions in everyday work
practices. Safety is a way of life at Western, a condition of
employment. Our program is based on four points.

-   Safety procedures or common sense must not be set aside by any
    employee, whether Federal or contract, to meet a project schedule or
    for personal convenience.

```{=html}
<!-- -->
```
-   Employees and contractors must believe that they have the right and
    the responsibility for identifying and taking action to reduce, if
    not eliminate, hazardous work environments and hazardous work
    practices.

```{=html}
<!-- -->
```
-   Managers and supervisors must lead by example and execute their
    responsibility to ensure each job is accomplished in a safe and
    healthful manner.

```{=html}
<!-- -->
```
-   Safety is a personal responsibility. Each individual makes the
    decision on what action to take to accomplish a task.

I am personally committed to a strong safety program and am asking you
to join me in this commitment. Together we can make Western a safe place
to work.
