§ 570.504 - Superseding leases.

(a) Consideration should be given to the execution of a superseding lease that would replace the existing lease when the changes or modifications to the space contemplated are so numerous or detailed as to cause complications, or they would substantially change the present lease.

(b) The justification and approval requirements in FAR subpart 6.3 and 506.3 must be complied with before negotiating a superseding lease if the value of the lease exceeds the simplified lease acquisition threshold. When the cost is less than or equal to the simplified lease acquisition threshold, the contracting officer may use simplified procedures outlined in 570.2 and explain the absence of competition in the file.
