Working in a CPFF environment where we have a PWS that is sometimes a little broad. If there is additional work that is requested, not originally planned, but determined to be "in scope," I'm looking for some basis to determine if the additional work should/could be Fee bearing? One party believes since we are in a cost environment additional cost can be requested for the additional work, but as it is in scope, it should not be subject to fee. Other party believes the opposite that just because it's in scope, does not automatically preclude the additional costs from being subject to additional fee. Thoughts? Thanks!
