DESCRIPTION OF SERVICES

The Contractor shall furnish all parts, labor material, equipment, transportation and supervision necessary to provide scheduled, preventive and predictive diagnostic maintenance services for nine (9) substations and one (1) 12kv switch yard (Switch Yard M) that are connected to the 69kV transmission and 12kV distribution systems respectively, located at Vandenberg Air Force Base (VAFB). The period of performance under this Contract is for a base year, four additional option years, and a 6month extension (at the end of the Contract). The option years and 6 month extension are exercisable at the sole discretion of the Government. The goal is to ensure high confidence levels in electrical service required for the entire installation. This Contract is primarily to perform routine maintenance and associated repairs on VAFB substations, as described in paragraphs 2.3 through 2.15 of this PWS. Other “repair” actions may be authorized IAW paragraph 4.

1.1 Coordinating Maintenance

Contractor is advised and understands that VAFB mission priorities and constraints will require the Contractor to be flexible in the scheduling of work to be performed in substations and switch yard. For example, launch protocols prohibit any work to be performed at substations and switch yard 48 hours prior to and 48 hours after a launch. Additionally, year round range activities will restrict the Contractor’s ability to perform work in substations. During periods of heightened national security, work in substations may be restricted. The Contractor shall work closely with 30 Civil Engineering Squadron (30CES) to schedule substation work and shall have the ability to quickly adapt to new or revised schedules as dictated by the VAFB mission. The contractor agrees that these constraints shall not be the basis for any claim for equitable adjustment.

1.2 Routine/Additional Maintenance

The Contractor shall perform routine maintenance at each substation on the items listed in this Performance Work Statement (PWS) at a minimum of once per year unless specifically called out differently in this PWS or otherwise required to meet the performance standards in this Contract or as otherwise required to maintain the substations in proper operational mode?. Routine maintenance includes the provision of labor, materials, equipment, and tools required to perform the maintenance tasks described in paragraphs 2.3 through 2.15 inclusive of this PWS. More frequent maintenance for many of these items may be required to meet the performance standards in this Contract. It is the Contractor’s responsibility to determine the frequency of each maintenance action to meet the performance standards in this Contract. The Contractor may propose additional maintenance or repair actions which are not specified in this PWS to meet the standards in this Contract. The Contracting Officer along with 30CES will determine whether or not to implement the suggested additional maintenance or repairs.

SCOPE OF WORK

Contractor shall provide routine substation maintenance and associated repairs as specified in the following paragraphs:

Maintenance Schedules During the first 30 days of the Contract the Contractor shall mobilize to perform the required maintenance, coordinate the initial schedule for access to the nine (9) substations and one (1) switch yard, and develop and submit a comprehensive maintenance checklist or database for tracking the required maintenance at each substation and switch yard. The Contractor shall submit a final maintenance schedule to include a checklist or multiple checklists for each substation and switch yard that describes the tests to be performed and the proposed recurring frequency for those tests as described in paragraphs 2.3 through 2.15 inclusive of this PWS. This final maintenance schedule shall be submitted by the Contractor NLT 30 days after Contract award. The final maintenance schedule shall be reviewed by 30 CES/CEO and 30 CES/CEP within 15 calendar days of submittal. The final maintenance schedule will be considered approved within 15 days after submittal unless 30 CES/CEO responds otherwise. Once the final maintenance schedule is approved by 30CES/CEO and 30CES/CEP, it will be used for the remainder of the Contract, unless otherwise revised by mutual agreement of Contractor and Government.”

4. REPAIRS

In the course of performing maintenance, the Contractor (or a Government representative) will likely encounter additional repairs (not specified in this PWS) that are necessary for the safety and reliability of VAFB substations. Repairs are defined as repairs for labor and materials under $50,000. The Contractor or the Government may identify a repair. If the Contractor identifies the repair, the Government will determine if the work can be performed in-house. If the repair cannot be performed by the Government, the following processes will be used to execute the repairs.
