DATE: August 12, 1991
TO: The Honorable Mayor and Board of City Commissioners
FROM: James W. Shira, P. E 6 '
City Engineer/Utilities Director
SUBJECT: Final Change Order - WWTP # 2
The first of two planned phases of the expansion of Wastewater
Treatment Plant # 2 is now complete.
During the course of construction, numerous issues arose that
individually, were too minor to justify the time and expense of
individual change orders.
Now that construction is complete, we have consolidated all of
these changes into one group which comprises a Final Change Order,
in the amount of $13,063 .23 .
The Final Change Order is 1.21% of the initial contract amount of
$1, 076, 600.00, which is a very low percentage for a project of this
size and complexity.
I recommend that the City Commission authorize the Mayor and City
Clerk to execute this Final Change Order in the amount of
$13, 063.23 .

Invoices for additional materials were supplied by the Contractor and
verified by PEC. As reflected in the proceeding chart, none of these
prices needed to be reduced, as they all appeared fair.
The additional time requested and approved was based on the latest long
lead item given tentative approval by the City of Ocoee. On June 24,
00842-3 0E-130/3.0
1991, oral approval of the proposed cost was obtained to change the
electrical service to the clarifier scum trough from 110 volt to 24
volts. Thirty days from June 24, 1991 allows for a final completion
date of July 25, 1991.
Actual installation for Item numbers 9 and 10, Flow Meter and
Gate/Ladder respectively, might not occur until August 6, 1991, due to
manufacturer's delay in delivery of these items to the Contractor.
