(a) Before executing a contract modification authorizing changes in either a designated subcontractor or inspection or production point, the contracting officer must consider the impact of the change on the contractor’s ability to satisfy contract requirements. Employ the same standards that were used to determine that the contractor was responsible (see FAR 9.1 and 509.1).
(b) The modification must identify the nature of the change and the effective date. In establishing an effective date, consider the time necessary for affected offices to take required actions.
