Attachment 4 Milestone Payment Schedule.xlsx

This is a Milestone Payment Schedule in spreadsheet format for the procurement of Special Test Equipment (STE) consisting of a Custom Thermal Vacuum Chamber, Thermal Shroud, and Thermal Conditioning Unit (TCU) for NASA Glenn Research Center under Solicitation 80GRC026R0011. The schedule outlines the contractor's payment structure tied to specific project milestones rather than a single lump-sum payment, allowing for staged compensation as deliverables are completed and accepted by the government.

The milestone payment approach enables NASA to distribute financial risk across the contract period while ensuring progress toward equipment delivery and installation. This payment methodology is typical for specialized equipment procurements where fabrication, assembly, and testing occur in distinct phases. The specific milestone definitions, payment percentages, and trigger events for each payment would be detailed within the spreadsheet tabs, establishing clear expectations for when the contractor may invoice the government and when NASA must issue payment upon verification of completed work. This structure protects both parties by linking compensation directly to measurable progress and delivery of the thermal chamber system components.
