Bonds: Performance and Payment Bonds required per FAR 28.102.

Magnitude of Construction: Between $1,000,000 and $5,000,000

Description:

The work primarily involves replacing the SCADA Uninterruptible Power Supply (UPS) at the Glen Canyon Dam facility. This includes demolishing and removing the existing SCADA UPS system and all associated components, as well as removing conduit and conductors that will not be reused. A new SCADA UPS system must be provided and installed along with all necessary components, including new conduit and conductors where existing ones cannot be reused.

Additional requirements:

• Perform all electrical modifications, terminations, labeling, testing, commissioning, and cutover to minimize downtime.

• Provide shop drawings, submittals, factory/start-up support, and training for operations staff.

• Deliver acceptance testing, as-built documentation, O&M manuals, and warranty support.

Agency Policies and Procedures In addition to FAR Part 43 (RFO), Bureau of Reclamation follows internal procedures to ensure timely definitization of equitable adjustments for change orders. These procedures include:

• Prompt negotiation of change orders upon identification of scope changes.

• Use of bilateral modifications whenever practicable.

• Establishment of target definitization timelines in contract administration plans.

Past Performance Data The Department of the Interior provides a page for Construction Contract Administration that includes definitization data for change orders under construction contracts. It lists the number of change orders and timeframes (e.g., 30 days or less, 31–60 days, etc.) for the past three fiscal years.
