Changes to Scope of Work The City of Nashua may, at any time, by written order, make changes to the general scope, character, or cost of this contract and in the services or work to be performed, either increasing or decreasing the scope, character, or cost of Independent Contractor's performance under the contract. Independent Contractor shall provide to the City of Nashua within 10 calendar days, a written proposal for accomplishing the change. The proposal for a change shall provide enough detail, including personnel hours for each sub-task and cost breakdowns of tasks, for the City of Nashua to be able to adequately analyze the proposal. The City of Nashua will then determine in writing if Independent Contractor should proceed with any or all of the proposed change. If the change causes an increase or a decrease in Independent Contractor's cost or time required for performance of the contract as a whole, an equitable adjustment shall be made and the contract accordingly modified in writing. Any claim of Independent Contractor for adjustment under this clause shall be asserted in writing within 30 days of the date the City of Nashua notified Independent Contractor of the change. When Independent Contractor seeks changes, Independent Contractor shall, before any work commences, estimate their effect on the cost of the contract and on its schedule and notify the City of Nashua in writing of the estimate. The proposal for a change shall provide enough detail, including personnel hours for each sub-task and cost breakdowns of tasks, for the City of Nashua to be able to adequately analyze the proposal. The City of Nashua will then determine in writing if Independent Contractor should proceed with any or all of the proposed change. Except as provided in this paragraph, Independent Contractor shall implement no change unless the City of Nashua in writing approves the change. Unless otherwise agreed to in writing, the provisions of this contract shall apply to all changes. The City of Nashua may provide verbal approval of a change when the City of Nashua, in its sole discretion, determines that time is critical or public health and safety are of concern. Any verbal approval shall be confirmed in writing as soon as practicable. Any change undertaken without prior City of Nashua approval shall not be compensated and is, at the City of Nashua's election, sufficient reason for contract termination.
