INCREASED OR DECREASED QUANTITIES OF WORK. The OWNER reserves the right and may from time to time, by written order, and without notice to any surety, make changes in the quantity or time of performance of the Work, as may be considered necessary or desirable and such changes shall not be considered as waiving or invalidating any conditions or provisions of the Contract or bonds. The CONTRACTOR shall perform all the Contract Work in strict compliance with the Contract Documents, and shall not make any changes to the Work without prior written authorization from the OWNER, in the form of a written Change Order. If such changes increase or decrease either the cost or the time necessary for the performance of the Work, then the parties will mutually agree upon an equitable adjustment to the price or time to perform the Work pursuant to the terms of the Contract.
INCREASED OR DECREASED QUANTITIES OF WORK. The Engineer shall have the sole right to increase or decrease any or all of the items specified in the Contract Documents, including the elimination of any one or more items. Such changes shall not invalidate the Contract. If quantities originally contemplated are materially changed, Contractor shall request a cost adjustment in writing in compliance with the Change Order requirements set forth in Section 3 herein. Approval of any such cost adjustment shall be at the sole discretion of the Engineer and the Engineer’s decision shall be final on any and all matters concerning cost adjustment. No payment for changed items shall be made to Contractor until both parties have signed the Change Order. Except in the case of minor changes in the Work approved or ordered by the Engineer in accordance with Section III (3)(D), or ordered by the Engineer in accordance with Section III (3)(C), Contractor may make substitutions only with the consent of the City, after evaluation and written approval by the Engineer and in accordance with a Change Order.
