Amendment / Modification

This amendment (A00001) to solicitation 127EAW26Q0025 provides responses to Requests for Information (RFIs) regarding the Electrical System Repair and Switchgear Replacement project at the San Bernardino National Forest Supervisor's Office.

Key clarifications include:

• Project Duration: The 180-calendar-day duration from Notice to Proceed through Final Completion includes all phases: shop drawings, procurement, delivery, installation, testing, commissioning, and final acceptance. The building will operate on a standby generator throughout the project.

• Drawings: A clearer version of the Single Line Diagram (SLD) has been provided as attachment 11. There are no detailed dimensional drawings of the existing gear, nor three-line electrical drawings or control schemes for the old switchgear. Existing panel schedules are outdated.

• Scope: The highlighted section in the provided diagram represents the total equipment scope. This includes connecting/disconnecting existing and rental generators.

• Material Lead Times: While the performance period remains 180 calendar days, contractors encountering long material lead times must notify the Forest Service with supporting documentation and formally request an extension, which will be evaluated case-by-case.

• Switchgear Type: The switchgear to be provided is Metal-Clad Switchgear.

• Duct Bank Work: Additional duct bank work may be required for code compliance and should be routed by the contractor's Licensed Professional Electrical Engineer in coordination with the manufacturer.

• Project Magnitude: The Independent Government Cost Estimate (IGCE) remains unchanged, despite potential higher costs due to design requirements and rework.

• Solicitation 127EAW26Q0025

• Project Name: Electrical system repair, Switchgear replacement. Supervisor's Office, San Bernardino National Forest, California.

• References to specific RFIs and their responses.

This amendment primarily provides clarifications and does not appear to change the proposal submission deadline or evaluation factors, but bidders should review all RFI responses carefully for any impact on their understanding of the scope and requirements.
