Are there any cases where a Work Order has been issued under a Task Order under an IDIQ contract. In other words, is there any prohibition to a Task Order being the ordering vehicle and issuing a Work Order under an existing Task Order?
This response is based on the information provided. We suggest you discuss with your contracting team, program manager and/or legal department as appropriate.
We do not have insight to any practices at NIH. It seems as if you would like to compete a task within the scope of the task order you awarded and then award to the winner. We suggest you create your competition/solicitation as normal using the less detailed FAR subpart 16.5 Fair Opportunities procedures. Put all offerors on notice you intend to select a winner and will modify the existing Task Order of the winner.
Please check with your legal to ensure there are no NIH policies precluding this approach.
