Posted on Federal Business Opportunities – –Use Solicitation Number NNC10ZH0023J or keyword “cryoceiling” Type of Procurement –Request for Proposal –Competitive Procurement –Small-Business set aside –Best Value Two Options identified in SOW –Disruption for Government convenience during assembly period 1 day 1 week –Warranty to cover workmanship after cryoshock and installation. Contracting Officer (Primary Point of Contact during proposal phase) –Mark A Rebholz Phone , Fax , - Contracting Officer Technical Representative –Henry Speier

Crew Exploration Vehicle Project Office Procurement Considerations Site-Specific Safety and Health Plan is required. Work Flow structured into three “phases” –Design –Off-site Fabrication –On-site Assembly and Acceptance Contract does not cover actual installation in the chamber –Only installation procedures. Coldshock and in-position testing are not included in contract. –Include warranty as an option to cover workmanship after cryoceiling is installed and tested in chamber. 14

Crew Exploration Vehicle Project Office Proposal Considerations Section L: Instructions, Conditions, and Notices to Offerors needs to be reviewed for preparation of proposal. – L15 through L18 define some of the specific information that will be required as part of the proposal package. –Each element needs to be addressed. Section M describes how the information provided in L15 through L18 will be evaluated. –Is approach fundamentally sound? Technically Project Control –Does offeror have capability to provide the promised services? –Is offeror’s approach unduly disruptive to government activities?
