“24. Damages for non-completion 24.1 If the Contractor fails to complete the Works by the Completion Date then the Architect shall issue a certificate to that effect. Such certificate shall (unless cancelled as hereinafter provided or revised in proceedings pursuant to Article 7B and clause 41C) be conclusive and binding on the Contractor until final ascertainment or agreement between the parties as to the matters to which it relates. In the event of a new Completion Date being fixed after the issue of such a certificate such fixing shall cancel that certificate and the Architect shall issue such further certificate under clause 24.1 as may be necessary. 24.2.1 Provided: - the Architect has issued a certificate under clause 24.1; and - the Employer has informed the Contractor in writing before the date of the Final Certificate that he may require payment of, or may withhold or deduct, liquidated and ascertained damages, then the Employer may, not later than 5 days before the final date for payment of the debt due under the Final Certificate: either: .1.1 require in writing the Contractor to pay to the Employer liquidated and ascertained damages at the rate stated in the Appendix… for the period between the Completion Date and the date of Practical Completion and the Employer may recover the same as a debt; or .1.2 give a notice pursuant to clause 30.1.1.4 or clause 30.8.3 to the Contractor that he will deduct from monies due to the Contractor liquidated and ascertained damages at the rate stated in the Appendix (or at such lesser rate as may be specified in the notice) for the period between the Completion Date and the date of Practical Completion. 24.2 .1 If, under clause 25.3.3, the Architect fixes a later Completion Date or a later Completion Date is stated in a confirmed acceptance of a 13A Quotation, the Employer shall pay or repay to the Contractor any amounts recovered, allowed or paid under clause 24.2.1 for the period up to such later Completion Date. 24.2 3 Notwithstanding the issue of any further certificate of the Architect under clause 24.1 any requirement of the Employer which has been previously stated in writing in accordance with clause 24.2 shall remain effective unless withdrawn by the Employer. 25 Extension of time 25.3 .1 If, in the opinion of the Architect….. The Architect shall in writing to the Contractor give an extension of time by fixing such later date as the Completion Date as he then estimates to be fair and reasonable… either: 25.3. .3 After the Completion Date, if this occurs before the date of Practical Completion, the Architect may, and not later than the expiry of 12 weeks after the date of Practical Completion shall, in writing to the Contractor either .3.1 fix a Completion Date later than that previously fixed if in his opinion the fixing of such later Completion Date is fair and reasonable….. 28 Determination by Contractor ….. 28.2. .1 If the Employer shall make default in any one or more of the following respects: .1.1 he does not pay by the final date for payment the amount properly due to the Contractor in respect of any certificate and/or any VAT on that amount pursuant to the VAT agreement; … the Contractor may give to the Employer a notice specifying the default or defaults (the “specified default or defaults”). … 28.2. .4 If … - the Employer repeats (whether previously repeated or not) a specified default… … then, upon or within a reasonable time after such repetition, the Contractor may by notice to the Employer determine the employment of the Contractor under this Contract. Such determination shall take effect on the date of receipt of such notice. 30 Certificates and payments 30.1. 1.1 The architect shall from time to time as provided in clause 30 issue interim certificates stating the amount due to the Contractor from the Employer, specifying to what the amount relates and the basis on which that amount was calculated; and the final date for payment pursuant to an Interim Certificate shall be 14 days from the date of issue of each Interim Certificate. If the Employer fails properly to pay the amount, or any part thereof, due to the Contractor under the Conditions by the final date for its payment, the Employer shall pay to the Contractor in addition to the amount not properly paid simple interest thereon until such payment is made…. 30.1. .1.4 Not later than 5 days before the final date for payment of the amount due pursuant to clause 30.1.1.1 the Employer may give a written notice to the Contractor which shall specify any amount proposed to be withheld and/or deducted from that due amount, the ground or grounds for such withholding and/or deduction and the amount of withholding and/or deduction attributable to each ground. 30.1. .1.5 Where the Employer does not give any written notice pursuant to clause 30.1.1.3 and/or to clause 30.1.1.4 the Employer shall pay the Contractor the amount due pursuant to clause 30.1.1.1. ….. 30.1. .4 Without prejudice to any other rights and remedies which the Contractor may possess, if the Employer shall, subject to any notice issued pursuant to clause 30.1.1.4, fail to pay the Contractor in full…by the final date for payment as required by the Conditions and such failure shall continue for 7 days after the Contractor has given….written notice of his intention to suspend the performance of his obligations….then the Contractor may suspend such performance …until payment in full occurs.”
“It would thus not be necessary for the employer to make a further requirement in writing under clause 24.2.1 but any existing requirement could only take effect in relation to those LADs which were properly recoverable based upon the new completion date.”
“when a new completion date is fixed, if the contractor has not completed by it, a certificate to that effect must be issued and it is irrelevant whether a certificate had been issued in relation to an earlier, now superseded, completion date.”
