Report Preliminary and Written Notice Under 52.217-9 in Contract Administration Posted July 19, 2019 Yeah, this clause, which I've used at least a hundred times, sucks, now that I am reading it carefully. Here is better....you listening FAR Council? Option to Extend the Period of Performance (Jul 2019) (a) The Government may extend the period of performance of this contract through the unilateral exercise of options under this clause, if two conditions are met: 1) The Government gives to the Contractor notice that the option has been exercised at least 5 days before the contract expires, and 2) The Government gives to the Contractor preliminary written notice its intent at least 60 days before the contract expires. (b) If these two conditions are not met, the option may be exercised only through a bilateral contract modification (supplemental agreement). (c) The total period of performance of this contract, including all extensions, shall not exceed 60 months.
