40．（1）the contractor shall，on the written order of the engineer，suspend the progress of the works or any part thereof for such time or times and in such manner as the engineer may consider necessary and shall during such suspension properly protect and secure the work，so far as is necessary in the opinion of the engineer．the extra cost incurred by the contractor in giving effect to the engineer's instructions under this clause shall be borne and paid by the employer unless such suspension is：
40．1收到工程師的書面命令後，承包人必須在工程師認為必要的時間，以其認為必要的方式，停止工程或部分工程的施工，只要工程師認為必要，還必須在停工期間妥善保護工程的安全。承包人根據本條款執行工程師指令而發生的額外費用應由業主承擔，除非此種停工是：
（a）otherwise provided for in the contract，or
契約另行規定的，或
（b）necessary by reason of some default on the part of the contractor，or
由承包人的某種違約而導致的必要停工，或
（c) necessary by reason of climatic conditions on the site，or
由工地的氣候條件導致的必要停工，或
（d）necessary for the proper execution of the works or for the safety of the works or anypart thereof insofar as such necessity does not arise from any act or default by the engineer or the employer or from any of the excepted risks defined in clause 20 hereof．
為正常施工或為整個工程或部分工程的安全而作的必要停工，而不是因工程師或業主的任何行為或違約而產生的，也不是因本契約第20條規定的任何除外風險引起的。
provided that the contractor shall not be entitled to recover any such extra cost unless he gives written notice of his intention to claim to the engineer within days of the engineer's order．the engineer shall settle and determine such extra payment and/or extension of time under clause 44 hereof to be made to the contractor in respect of such claim as shall，in the opinion of the engineer，be fair and reasonable．
承包人在收到工程師命令後xx天內應書面通知工程師，要求賠償，否則將無權得到額外費用。如工程師認為承包人的要求公平合理，他必須按本契約第44條的規定，處理並決定此種支付給承包人的額外費用和／或停工時間。
（2）if the progress of the works or any part thereof is suspended on the written order of the engineer and if permission to resume work is not given by the engineer within a period of ninety days from the date of suspension then，unless such suspension is within paragraph（a)，（b），（c） or（d）of sub—clause（1）of this clause，the contractor may serve a written notice on the engineer requiring permission within days from the receipt thereof to proceed with the works，or that part thereof in regard to which progress is suspended and，if such permission is not granted within that time，the contractor by a further written notice so served may，but is not bound to，elect or treat the suspension where it affects part only of the works as an omission of such part under clause 51 hereof，or，where it affects the whole works，as an abandonment of the contract by the employer．
