• Operational Availability threshold: 95.00% (objective 98.00%).

• Maintainability threshold: no more than four (4) hours of system downtime for 90.00% of downtime occurrences.

• The PWS covers Post Deployment System Support (PDSS) for GCSS-MC/LCM Increment 1.

• Specific locations for performance are not detailed in this document, but travel may be required to CONUS/OCONUS locations.

• Security: Adherence to DoD and Marine Corps security regulations, including personnel clearances, access control, and cybersecurity requirements (DoDI 8500.01, DoDI 8510.01, etc.).

Request for Information (RFI)

This RFI is issued by the Marine Corps Systems Command (MCSC) to conduct market research for capability support and decommissioning services for the Global Combat Support System Marine Corps (GCSS-MC). GCSS-MC is an Oracle-based Enterprise Resource Planning (ERP) system used for logistics, supply, and maintenance operations. This RFI is for information and planning purposes only and does not constitute a Request for Proposal (RFP).

The government is seeking industry interest in services for:

• Transition-In: A period of up to six months for vendors to gain knowledge and experience with GCSS-MC to transition to full support status.

• Capability Support: Maintaining the GCSS-MC system in its current state, ensuring operational availability, reliability, maintainability, and security. This includes troubleshooting, interface management, help desk support, system monitoring, performance management, and cybersecurity.

• Decommissioning Services: Planning and executing the complete decommissioning of the GCSS-MC system, including data archiving, hardware disposition, and stakeholder communication.

• Capability Support: Maintain current system performance (98.7% availability, 99.9% reliability), manage approximately 288 maintenance change requests per quarter, and handle over 60 daily help desk requests.

• Decommissioning: Develop a detailed Decommission Plan, manage data archiving, securely dispose of hardware, and provide comprehensive documentation.

• The RFI does not commit the government to a contract.

• The decommissioning process is expected to be completed within two to four years.

• Questions & Comments Deadline: Friday, May 1, 2026, by 12:00 PM.

• RFI Responses Due: Thursday, May 14, 2026, by 5:00 PM EST.

• Responses are limited to 20 pages and must be submitted electronically via email.

• Information requested includes company overview, point of contact, contract vehicles, past performance, and a capability narrative.

• Not specified in this RFI.

• This RFI does not include system enhancements or modernization.

• An attached Legacy Performance Work Statement (PWS) is provided for historical context only and is not binding.

• Responses will be used to potentially modify or clarify information for a future solicitation.
