Notice Number: MSC 2218
Project Number: M08019

Project Title: 13.2 KVA West Underground Electrical Updates, West Loop
Estimated Construction Cost: $337,000.00

Project Description

The State of Colorado acting by and through the Board of Trustees of Mesa State College for
the use and benefit of Mesa State College, is seeking submittals from qualified high voltage
electrical contractors interested in providing construction services for the extension of the west
radial circuit (a.k.a. the “West Loop”) on our primary campus 13.2 KV distribution at our main
campus in Grand Junction, CO. The current phase of work will extend the existing distribution
system an additional ± 2,500’ from an existing switch gear adjacent to Building A at our newest
residence hall (North Ave. Residence Halls), north within existing City right-of-way along the
east side of Cannell Ave. to an existing alley south of the softball fields (north of Texas Ave.).
The new line will then turn east, on the north side of the alley where it will connect into an
existing pull vault near the southwest corner of Saunders Field House before turning north
where it will terminate in the main 13.2 KV service entrance equipment located adjacent to
Orchard avenue at the north end of the campus (refer to exhibit A).

All conduit installation will be accomplished via directional bore to minimize disruption within City
right-of-way, inconvenience to students and residents and to minimize surface restoration

      sales and use tax payment forms, the completion of the final punch list and the calling for final
      inspection, within 14 calendar days, if applicable, from the date of substantial completion. In
      accordance with Article 46 of the General Conditions of the Contract, Time of Completion and
      Liquidated Damages, failure to complete the work within the agreed number of calendar days
      shall be considered breach of contract and subject the bidder to liquidated damages to the extent
      specified in Article 54D of the General Conditions of the Contract.

   2. The right is reserved to waive informalities or irregularities and to reject any and all Bids.

   3. Each Bid shall be submitted on the required Bid Form and must be accompanied by a Bid Bond
      on State Buildings Programs Bid Bond Form Sc-6.14 in an amount not less than 5% of the total
      Bid. The Bid Bond may also be (1) a cashier's check or (2) a certified check made payable to the

       law.
    6. Requirements for bidding will include qualifying with Colorado State Buildings Programs for construction
       projects of $150,000 or more at least two (2) working days prior to bid opening. If you are not yet
       qualified with State Buildings, locate the online form SC9.1, Contractors’ Registration from the web site
       http://www.Colorado.gov/dpa/dfp/sbrep (Click on the navigation button State Buildings, then Contractor’s

       Registration Form). Complete the form and submit electronically to the Office of the State Architect.
 


Scope of Services
Qualified high voltage electrical contractors shall supply all materials, equipment and labor for
the installation of all vaults, cables, cable accessories and miscellaneous materials to complete
the work included on Exhibit A. Additional work will include the following;

    1) Coordination with Mesa State College, the City of Grand Junction and neighbors
       impacted by the construction project. The City of Grand Junction has granted
       permission to install the electrical feed within City right of way along the east side of
       Cannell Ave. but still requires the successful contractor to obtain a Work in the Right of
       Way permit before work can begin.
    2) Provide a traffic control plan and construction traffic control for all work completed within
       City right of way.
    3) Provide utility locates and potholes necessary to determine exact vertical and horizontal
       locations of utilities that will be crossed with the new electrical lines.

Minimum Requirements

The substantial hazards associated with high voltage electrical work and the specialized equipment
required make it necessary to have specific requirements for high voltage electrical contractors working
on the Mesa State College campus. Mesa State College owns and operates its own 13,200 Volt AC
electrical distribution system, also known as a “primary-metered” system. The following requirements are
general in nature and not intended to be all inclusive nor are they intended to cover all circumstances that
may arise. Contractors approved for this construction project shall meet the following standards in
addition to the State of Colorado minimum requirements;

    1) Have successfully completed at least three other projects of similar scope and complexity in the
       previous five calendar years.

    2) Employ qualified personnel adequately trained and certified to accepted high voltage industry
       practices.

    3) Maintain industry accepted standards for the ratio of journeymen to apprentices.

    4) Maintain monthly safety meetings to emphasize awareness of hazards associated with high
       voltage electrical work.

    5) Have the required safety and personal protective devices readily available for all personnel.

    6) Demonstrate a safe work history by maintaining a loss-time work history at or below acceptable
       industry standards.

    7) Maintain and have available all specialized equipment for the installation and maintenance of high
       voltage electrical systems: cable pulling equipment, bucket trucks, digger-derrick line trucks,

                                                                                                           4
         cable termination and testing equipment to include high-potential testing, high voltage testing and
         measuring equipment, etc

  A.     Provide and install in new or existing duct bank new MV-90 cables and 600 V grounds. Termi-
         nate at both ends.

1.3 QUALITY ASSURANCE

  A.     The Contractor shall provide a quality assurance and control program in which the cable is
         manufactured, tested, and installed in accordance with the intent of these specifications,
         applicable codes, standards, and manufacturer's recommendations.

  B.     The Contractor shall submit a schedule of pulls prior to installation that has been reviewed and
         recommended by the cable manufacturer for approval of Owner and Engineer. The schedule of
         pulls shall include Contractor’s proposed method of pulling cables, including procedures and
         materials (pull wire, lubricant, dynamometer, etc.).

  C.     The installing contractor shall certify in writing that the cable installation meets the requirements
         of the cable manufacturer addressing maximum pulling tension(s), allowable sidewall
         pressure(s), and installed bend radius limitations. All cable pulls greater than 200' or
         incorporating one or more 90 degree bends must incorporate the use of a tension measuring
         device, and all cables must pass an installed d.c. high-pot test (by Contractor) as set forth in
         ICEA S-68-516. In addition, partial discharge testing shall be performed by an independent
         testing organization (under separate contract to Owner) after all cables are installed and
         energized. Written documentation of all tension measurements and d.c. high-pot test results
         must be submitted to Owner and Engineer.

  D.     Qualification of Cable Terminations and Splices: Before assigning any cable handling
         personnel to the job, the Contractor shall provide Owner with documentation that each individual
         is a journeyman, experienced in splicing and terminating the 15 kV cable in accordance with
         Section 16010. Upon approval of this documentation, the individual shall demonstrate their
         capabilities to Owner if requested. All material and labor required for this work shall be the
         responsibility of the Contractor. If, during the course of the project, there is a change in

  A.     See Section 16010.

2.2      SPLICES, TERMINATIONS AND ACCESSORIES (15,000V)

  A.     See Section 16125.


PART 3 - EXECUTION

3.1      CONDUCTORS

  A.     Install three medium-voltage conductors and one low-voltage ground conductor per duct.

  B.     Approved pulling compounds may be used. Liberal use of a non-setting cable lubricant
         (Polywater or equal) shall be employed for each cable pull. The residue shall be cleaned from
         the conductors and raceway entrances after the pull is made per manufacturer's
         recommendation, where accessible.

  C.     Pulleys or blocks shall be used for alignment of the conductors when pulling. Pulling shall be in
         accordance with manufacturer's specifications regarding pulling tensions, bending radii of the
         cable, and compounds. Pulling methods and procedures shall be submitted to and approved by
         Owner.

  D.     Use dynamometer and record peak pulling tension for each pull where required. Provide record
         of pulling tension Owner review.

  E.     Install cables in a delta formation along walls, supported by cable saddles or racks in manholes
         as shown on the drawings. Securely lace cables to supports after fireproofing. Maintain
         separation of loop segments as much as practical. Where one set of cables crosses another
         set or runs parallel to another set, maintain a minimum separation of four inches.

  F.     Arrange cable in manholes to avoid interference with duct entrances.

3.2      PULLING REQUIREMENTS

  A.     Pull cables slowly and steadily using a capstan. Do not stop once the pull is started unless
         absolutely necessary. Do not pull faster than 50 feet per minute.

  B.     If basket grips are used, securely fasten the back end of the grip to the cable.

  C.     If basket grips are used, cut the pulling end of the cable well behind (min. 5') the area covered
         by the grip. This length is referred to as the "spoil." Estimates for spoil shall be the
         responsibility of the Contractor and shall be included in the contract price.

  D.     The cable must be trained into the raceway in a manner that will prevent its dragging on the
         edge of the raceway mouth. This will minimize pulling strain and jacket damage.

  E.     Seal medium voltage cable ends during and after the pull. Apply high voltage putty or silicone
         caulking at each end, and then overwrap each end with tape to keep out moisture. For longer-

         term storage, provide cable end sealing caps to prevent water ingress and maintain cable
         integrity.

3.3      FIELD TESTING

  A.     General Requirements:
         1.  When all terminations and splices have been made, all new cables shall be tested prior to
             connections to equipment. Refer to NETA ATS, 2003, Part 7.3.3. DC Hi Pot testing shall
             be performed by the Contractor.
         2.  DC high-potential test shall be made on each new cable using test voltages equal to a
             maximum of 80% of the final factory DC test. High potential testing shall be performed in
             the presence of the Engineer. The field potential test shall not be applied to potential
             transformers, control power transformers, switchgear, power transformers, lightning
             arrestors, or other equipment not capable of withstanding the test voltage that is
             connected to the cable system.
             If splicing to existing cables is required, the entire cable, when splicing is completed, shall
             be tested at a test voltage not exceeding 60% of the factory test value. Before testing,
             disconnect all cables that are being tested at the first point of terminations.
         3.  If found to be defective by these tests, all new cables, when furnished and installed by
             Contractor, shall be replaced by the Contractor at no cost to UCHSC.

  B.     Preparatory Steps:
         1.   Both ends of cable shall be disconnected and free of all equipment. Adequate safety shall
              be taken so that personnel cannot come into contact with ends when test is being made.
         2.   Each cable shall be given a continuity test and identified with phase designation (A, B, C).
         3.   The cable ends opposite to the end on which the test set is going to be connected shall be
              completely sealed to prevent corona from forming at sharp ends of cable. Wrap
              completely, tightly, and without voids with “Scotch” brand #33 (or equal) electrical tape.
         4.   Ground all shields to the same ground point. No. 6 AWG solid wire is usually adequate.
              Do not use stranded wire.
         5.   Connect high voltage lead of test set cable tested; seal connection to prevent corona from
              forming.
         6.   Cables not being tested are to be grounded to the same common ground as the shields.
         7.   Connect and set controls of Hi-Pot tester as recommended by test set manufacturer.
         8.   Make final safety check:
              a.   Cable ends supported securely and hanging free of all equipment.
              b.   Ends are guarded and protected.
              c.   All grounds are secure.

  C.     Test Voltages:
         1.   Initial Acceptance Test Voltage (DC)
              a.     New 15 kV cable initial test voltage shall be 50 kV, or 35 kV for new cables that
                     include splices to existing cables.
              b.     If initial acceptance test is unsatisfactory, subsequent tests shall be performed at the
                     Engineer’s direction, or the cable shall be replaced.

  B.    Fuse-mounting jaw contacts shall incorporate an integral load interrupter that shall permit live
        switching of fuses with a hook stick.
        1.   The integral load interrupter shall be in the current path continuously. Auxiliary blades or
             linkages shall not be used.
        2.   Live switching shall be accomplished by a firm, steady opening pull on the fuse pull ring
             with a hook stick. No separate load-interrupting tool shall be required.
        3.   The integral load interrupter shall require a hard pull to unlatch the fuse to reduce the
             possibility of an incomplete opening operation.
        4.   Internal moving contacts of the integral load interrupter shall be self-resetting after each
             opening operation to permit any subsequent closing operation to be performed
             immediately.
        5.   Circuit interruption shall take place completely within the integral load interrupter with no
             external arc or flame.
        6.   The integral load interrupter and the fuse shall be provided with separate fault-closing
             contacts and current-carrying contacts. The fuse hinge shall be self-guiding and, together
             with the fault-closing contacts, shall guide the fuse into the current-carrying contacts
             during closing operations. Circuit-closing inrush currents and fault currents shall be picked
             up by the fault-closing contacts, not by the current-carrying contacts or interrupting
             contacts.
        7.   Integral load interrupters for fuses shall have a one-time duty-cycle fault-closing capability
             equal to the interrupting rating of the fuse, and a two-time duty-cycle fault-closing
             capability of 13,000 amperes rms asymmetrical at 14.4 kV or 25 kV. The duty-cycle fault-
             closing capability defines the level of available fault current into which the fuse can be
