Answered: NEC3 ECC: Under NEC Option F, is Subcontracted work within the Contractor's identified works a disallowed cost?

Reading the contract as :
- the Contractor has tendered 'prices' (in italics)  for "work which the Contractor will do himself" (in the Contract Data Part 2); and
- a Disallowed Cost "is a payment to a Subcontractor for - work which the Contract Data stated the Contractor will do himself"
then it is pretty clear that it is a Disallowed Cost.

The question becomes 'is the Contractor paid at all for this work now ?'
