GRU is working towards replacing all of our existing 138kV oil circuit breakers (OCB) with new 138kV SF6 breakers.

GRU currently has 31 OCBs in service and plans to replace 4-6 breakers per year. GRU will provide the new 138kV SF6 (Siemens) breakers for each project. Typical project scope information and drawings have been included as part of this specification. High level, the scope for each breaker replacement will include the following:

• Engineering design

• Procurement of all needed material except the new 138kV SF6 breakers

• Modifying the existing OCB foundations while the breakers are still in service

• Installing new conduits

• Replacement of control cables

• Removal and disposal of the existing 138kV oil circuit breaker

• Install of new 138kV SF6 breaker

• Finalizing all project documentation and drawings associated with the project

GRU also intends to utilize this specification for the replacement of any 138kV SF6 breakers that are in need of replacement.

The Contractor shall furnish all labor, equipment and material (unless indicated provided by GRU), tools, transportation, supervision and any other services necessary to complete the work in accordance with the attached drawings and these specifications. Project completion shall result in a fully tested and commissioned 138kV SF6 breaker based on the requirements within and referenced by this specification.

The Contractor shall not take advantage of any apparent errors and/or omissions discovered in the drawings, but immediately notify the GRU Company Representative of such discovery. Once notified, the GRU project representative will then make such corrections and interpretations as necessary to reflect the actual spirit and intent of the drawings and specifications.

Deviations from this specification or referenced documents shall not be made without written approval from the GRU contact or his designee.

3.0 SCHEDULE

Site visits will not be scheduled prior to the bid due date. Contractors shall base their bids on this RFP.

The Contractor’s bid shall include a work schedule in the form of a Gantt chart detailing milestones and activities necessary to complete this project. The Contractor shall be responsible for maintaining an accurate schedule of work that ensures completion of this project by the date indicated on the Purchase Order. Contractor’s schedule shall be submitted to GRU for review and weekly progress updates shall be provided to GRU throughout the project.

4.0 MEETINGS

Contractor shall have a kickoff meeting with GRU prior to beginning the design for each breaker replacement.

The goal of this meeting will be to go over any unique project requirements and turnover available existing design documentation to the contractor.

Each breaker replacement will also require a site visit to confirm accuracy of the existing substation documentation. For example, GRU does not typically have as-built drawings for the existing oil circuit breakers.
