Our SB was issued a FFP and IDIQ unfunded contract which included a list of applicable WDs and CBAs. We received a funding task order for the FFP portion of the contract that included a list of updated WDs. We are now receiving individual task orders for the IDIQ portion of the contract and each one of those has its own updated WD, different revisions than either previous contracts. Most of this work is being subcontracted out FFP and IDIQ. None of the RFPs for the IDIQ work I have seen call out what WD will be used for that task. On other contracts we typically receive task orders that use the WDs from the main contract. This will mean a bit more tracking and flowing down of WDs to our subs, some are doing both FFP and IDIQ work. Just want to see if this is normal since it is not something I have seen before.
