(1) Substantial completion of the work is delayed by causes for which the Contractor is not responsible under this contract; and
(2) The actual or projected substantial completion date is later than the date required by this contract for substantial completion.
(c) The Contractor shall not be entitled to an extension of time if the Contractor has not updated the project schedule in accordance with the contract.
(d) The Government shall not be liable for any costs to mitigate time impacts incurred by the Contractor that occur less than 30 calendar days after the date the Contractor submits a request for extension of time in compliance with this clause.
