Sometimes the causes of delay are continuing in nature and in such events the engineer is empowered to determine the interim extension of time. The provision for compensation in addition to the extension of time can be worked as follows.

If, in the opinion of the engineer, any of the salaried men or plant and equipment used by the contractor at the site in performance of the contract is necessarily kept idle, on account of any act or omission of the owner or engineer and without the fault of the contractor, the contractor shall be entitled to reasonable compensation. This compensation shall be an amount equal to that which may be pay during such period of idleness for the services of such isle salaried person and expenses connected therewith plus a sum that may be have to pay in the form of rent for such idle plant and equipment. No compensation shall be paid to the contractor unless the contractor shall have submitted a claim with full details in writing to the engineer within one month of cause of such claim occurring. Here is suggested clause dealing with extension of time.

If the contractor be delayed at any time in the progress of the work by any act or omission of the owner or engineer or by acts of god, or by the act of another contractor employed by the owner, or by acts of Government, or by hostile acts of enemies, or by fire, causes delay in transportation or unavailable casualities.
