insurance that may be required covering public liability for injury to persons and
property, the cost of workmen's compensation insurance, federal social security, and any
other costs based on payrolls, and required by law. The cost of extra work shall not
include any cost or rental of small tools, buildings, or any portion of the time of the
Contractor, his project supervisor or his superintendent, as assessed upon the amount of
extra work, these items being considered covered by the 15 percent added to the
reasonable cost. The reasonable cost for extra work shall also include the premium cost,
if any, for additional bonds and insurance required because of the changes in the work.
17.3. In the case of extra work which is done by Subcontractors under the specific
contract, or otherwise if so approved by the Engineer, the 15 percent added to the
reasonable cost of the work will be allowed only to the Subcontractor. On such work an
additional percentage of the reasonable cost (before addition of the 15 percent) will be
paid to the Contractor for his work in directing the operations of the Subcontractor, for
administrative supervision, and for any overhead costs. Such percentage shall be in
accordance with the following schedule: reasonable cost up to and including $50,000—
10 percent; next $50,000 to and including $100,000—7™% percent; greater than
$100,000—5 percent.
17.4 The Engineer may authorize minor changes or alterations in the work not
involving extra cost and not inconsistent with the overall intent of the contract
documents. These shall be accomplished by a written field order. However, if the
Contractor believes that any minor change or alteration authorized by the Engineer
entitles him to an increase in the contract price, he may make a claim therefore as
provided in article 21.
