47．（1）if the contractor shall fail to achieve completion of the works within the time prescribed by clause 43 hereof，then the contractor shall pay to the employer the sum stated in the contract as liquidated damages for such default and not as a penalty for every day or part of a day which shall elapse between the time prescribed by clause 43 hereof and the date of certified completion of the works．the employer may，without prejudice to any other method of recovery，deduct the amount of such damages from any monies in his hands，due or which may become due to the contractor．the payment or deduction of such damages shall not relieve thecontractor from his obligation to complete the works，or from any other of his obligations and liabilities under the contract．
