Even if express provision were to be included in the contract for the employer to postpone all or any part of the works, such provision may not be used to postpone the entire project. The postponement of any works under an express contract provision should be limited to only a reasonable period in the context of the contract involved. Any deferment will be to grant an appropriate extension of time to the contractor and compensate him for any loss and expense which the contractor may have incurred consequent to the delay.
