significant delays due to the Contractor. The purpose of this scope of services is to provide additional
construction phase services to account for the delays. The original scope of services assumed a 36-

visit to witness pump testing and full start-up.
6. Opinion of Probable Construction Cost(OPCC)—An OPCC for unfinished work within Lochner's
design responsibilities will be developed.
