Answered: Must the answers to Tender Clarification questions (pre-tender) be considered as part of the Contractual Documents once awarded?

The answer is 'No' they do not as there is an entire agreement clause in the contract (see clause 12.4 in NEC3 ECC).

However, if the contract is unclear - and AFTER other principles for the interpretation of contracts and those in the contract have been applied - if there is still ambiguity or inconsistency, the responses might well inform the interpretation.
