The National Park Service is conducting a Sources Sought Notice to identify qualified contractors capable of providing diagnostics, repair, and corrective maintenance services for six Gillig diesel hybrid electric buses at Yosemite National Park in California. This is a market research announcement only and does not constitute a formal solicitation or request for quotation. Contractors must be either an authorized Gillig repair facility or Gillig factory-certified technician to be considered eligible. All diagnostic, disassembly, rebuilding, calibration, and testing work must be performed at an authorized Gillig repair facility, with mobile or field repairs prohibited unless pre-approved in writing by the Contracting Officer.

No incumbent contractor or current vendor is identified in this notice. The work involves transporting, diagnosing, repairing, and testing two 2005 Gillig buses requiring wire harness replacement and four 2011 Gillig buses requiring engine replacement, DPIM module replacement, or similar repairs.
