NASA may occasionally retain the property administration and plant clearance function, such as for contract work performed at the installation awarding the contract and not subject to the clause at
1852.245-71, Installation-Accountable Government Property. In these cases, property administration shall be performed in accordance with 1845.3 through 1845.6, and plant clearance shall be performed in accordance with
FAR Subpart 45.6 and 1845.6. Under the clause at 1852.245-71, property administration and plant clearance are neither delegated nor retained; they are simply not required because the property is treated as installation rather than contract property.
