Could you please clarify your answer below- does it mean that work done before the termination date will still carry Defect Liability post the termination date for the remaining 6 months of the Defects Liability period?
Termination does not mean that the contract ceases to exist for all purposes, any rights already accrued by the parties remain unless the termination provisions state otherwise. So in your scenario the Contractor will remain responsible for any Defects in completed work for the next 6 months.
Your question was:
NEC ECC: If the Contractor terminates the contract under reason R16 what are the obligations of the Contractor to the Employer with regard to the defects liability period
