It is the responsibility of the Contractor to submit an Extension of Contract Time Request, Form 1100A, for additional time beyond that allowed in the contract. An extension of time to file is not an extension of time to pay.Read the Line-by-Line Instructions before completing Form 4. This request is more formal than the notice of delay, and the actual procedure to request a time extension should be outlined in the contract. You must make a written request to extend or renew the permit. The request must include a schedule for completion of the work. In Michigan, all contracts, except employment contracts, have been construed to include an implied duty of good faith and fair dealing. Changes, extras, adjustments, time extensions, modified originals, overruns, and all other changes are all to be evaluated in the same manner. A recipient may request to extend the time to begin any construction beyond the 24 month period, with an amendment request to the Department. To qualify for an extension of time claim, this must be considered adverse weather.
