Please allow me to propose a hypothetical, and get your feedback.
IDIQs cannot have IDIQs under them under current law and regulation. Once an IDIQ is created, the task/delivery orders under them must be definitive (e.g., specific items, labor categories, price/cost, period of performance, etc.). The size and duration of the task order impacts the level of detail. Small task orders have explicit detail. However, many large dollar IDIQ task orders are far more broad. If a task order under an IDIQ is measured in the tens of million of dollars and has option periods, it is very likely that further definition is occurring at the day to day level with the COR. None of that definition is changing the scope of the task order, but is necessary for effective project management. It would seem to be better contract administration if this is completed explicitly in the order itself, perhaps as a sub-line item. This level of detail could not be known at contract/order award, but if added to an order as a modification, it certainly creates the appearance of an IDIQ under an IDIQ.
So . . suspending the natural response of this message board to live within the current set of rules, I'd like to know how to recommend that we change the FAR or agency supplements to allow for this to occur. Several agencies allow for "Technical Direction" to serve this purpose (e.g., NAVY, EPA). Neither reach the level of codifying in the task order, but the concept of further definitization is clearly there.
If you could change the rules to allow an IDIQ to have an task order under it that evolved over time, with the details becoming codified, where would you make the changes in the rules?
My initial starting point would be FAR 16.505. There is an anchor for modular contracting for IT there (FAR 39.103[a]), and this is a variant of that for any scope area.
Another idea would be to allow for the creation of BPAs under IDIQs, as BPAs under GSA Schedule already serve this under FAR 8.4.
Any other bright ideas out there?
