The COUNTY shall have the right, within the general scope of the work and without notice to any surety or sureties of the CONTRACTOR, to make changes in the Work, including, but not limited to, changes in the Plans and Specifications pertaining to beach width, beach elevation, fill volume, beach length, environmental protection, contract time, contract price, in or to the method or manner of performance of the work, in or to equipment, materials, service or site, in or to the mode or manner of payment for the Work, or directing a change in the rate of performance of the Work. All changes shall, except in the case of emergencies endangering the safety of personnel or property, be made by modification of the Contract Documents or by written change order duly executed by the COUNTY, ENGINEER, and CONTRACTOR. Work necessary in connection with emergency changes in the Work shall be strictly limited to the minimum necessary to alleviate the immediate emergency; Work beyond such minimum shall be undertaken only pursuant to a properly issued change order received from the COUNTY. The CONTRACTOR shall promptly comply with any and all written change orders issued by the COUNTY, notwithstanding any disputes. No such change order shall be deemed to invalidate the contract.

17.2. No Adjustment of Unit Price. The quantity of material to be placed on the beach is based on beach surveys conducted prior to the construction of the project. It is almost certain that the forces of wind and waves have altered the beach since development of the estimated fill quantity for the project. No adjustment shall be made in any unit price of the contract for changes ordered by the COUNTY that cause an increase or decrease less than or equal to twenty-five percent (25%) in the amount of the work, or by the estimated quantities provided in the Contract Documents of fill material that is to be placed within fill templates. It is further provided, however, that no adjustments shall be made in the contract price or time of performance for either lump sum or unit price work if the change is expressly or reasonably implied by the Plans and Specifications or is incidental thereto, or if the Work becomes more difficult than the bid price and Contract Documents would reflect, or if CONTRACTOR failed to protest, negotiate, comment, or otherwise call to the COUNTY's attention, in writing, any omissions, ambiguities, or conflicts in the Contract Documents that the CONTRACTOR could have discovered prior to the submission of their bid or execution of the contract. An equitable adjustment may be made in the Contract Price for Unit Price Contracts if changes ordered by the COUNTY cause the applicable quantity set forth in the Contract Documents to be decreased by more than twenty-five percent (25%). Such adjustments may be made only for that portion of work that is less than seventy-five percent (75%) of the estimated quantity and shall be supported by data provided by the CONTRACTOR to the COUNTY, which demonstrate justification for the adjustment in Unit Price.
