About this file
This is an Amendment of Solicitation/Modification of Contract (SF 30, Amendment 00002) issued by NASA's Marshall Space Flight Center on February 27, 2026, for solicitation 80MSFC26R0002, the Engineering Services and Science Capability Augmentation (ESSCA) II contract.
The amendment updates Attachment L-1 Excel Pricing Model by providing Government-supplied WYE (Work Year Equivalent) numbers for LaRC (Langley Research Center) and MAF (Marshall Analysis Facility) for Years 3-8, removing yellow highlighting from previously unfilled cells in specified ranges. As a result of this change, the proposal submission due date has been extended to Monday, March 16, 2026, at 2:00 p.m. Central Time. The amendment also revises Section L, Volume II Cost Volume Instructions, subsection a.9, to clarify which subcontractors must provide information related to audit of their accounting systems. Two replacement solicitation files must be used in proposal submission: the Sections J-M document with change bars identifying modified language and the updated Excel Pricing Model. Offerors are required to acknowledge receipt of this amendment via SF 30 or transmittal letter by the proposal due date; failure to do so may result in proposal rejection and ineligibility for award. The time for submitting questions has closed and no additional questions will be accepted. All other terms and conditions remain unchanged.
