delivered the opinion of the court:
The contract in this case for the removal of certain buildings and improvements from Camp Meade, which were paid for by the plaintiff September 7, 1923, provicled that-the buildings should be dismantled and removed within nine months. The contract contained no provision for liquidated damages or penalty for failure to complete the work within the time specified but contained a provision that no extension of time would be granted. The time limit was certainly for the benefit of the defendant which it could not insist upon if it delayed the contractor in the performance of the work. The rule is well established that where one party to a contract demands strict performance as to time-by the other he must comply with all the conditions requisite to enable the other party to perform his part, and the failure on the part of the one demanding performance to do all required of it to enable the other party to complete the work within the time limit operates as a waiver of the time provision of the contract, and the contractor is permitted to complete the work within a reasonable time.
