GSA Form 1649: Notification of Federal Supply Schedule Improvement
GSA Form 1649, Notification of Federal Supply Schedule Improvement, is a General Services Administration form, Rev. 12/1998 (printed REV. 12-98), and GSA hosts it in its forms library. GSA's page lists FSS P 2901.2A as its authority or regulation. The PDF itself prints no prescribing line.
The front has numbered blocks for the schedule number (FSG/FSC, part and section), schedule title, proposed effective date, the contracting officer and telephone, estimated or actual information on contracts, items and NSNs or SINs, SINs or product lines with their values, the impact on the current schedule, schedule dollar values, the action and background, and a justification. Block 13 is signed by the director of the submitting office, and a For FCS Use Only strip records the date received and a control number. Block 15 on the back is for additional information.
