Clause 62.5 allows the period for reply to a quotation (or for submission of a quotation) to be extended by agreement provided it is before the submission or reply is due.
Clause 62.6 deals with non response to the quotation but is seemingly silent over further extensions to the period for reply. This would suggest that once the initial notification of non response has been submitted, the contract does not allow for there to be an extension to the assessment period. In this instance, the PM would have two weeks from the date of the second notification to respond with acceptance, rejection, to provide a revised quotation or to notify the contractor that they will be doing their own assessment, else the quotation will be deemed accepted.
Is this a correct interpretation of the contract?
