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 Professional Engineer's
performance under the contract. Professional Engineer 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 Professional Engineer should proceed with any or all of the proposed
change. If the change causes an increase or a decrease in Professional Engineer'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 Professional Engineer for adjustment under
this clause shall be asserted in writing within 30 days of the date the City of Nashua notified
Professional Engineer of the change.

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 Professional Engineer should proceed with any or all of the proposed change.
Except as provided in this paragraph, Professional Engineer 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.
