CITY OF LODI COUNCIL COMMUNICATION
AGENDA TITLE: Acceptance of Improvements Under White Slough Water Pollution Control
Facility Expansion Contract
MEETING DATE: August 19, 1992
PREPARED BY: Public Works Director
RECOMMENDED ACTION: That the City Council accept the improvements under the
"White Slough Water Pollution Control Facility Expansion"
contract, and direct the Public Works Director to file a
Notice of Completion with the County Recorder's ffice.
BACKGROUND INFORMATION: The contract was awarded to Alder Engineering and
Construction Company of Salt Lake City, Utah, on
January 17, 1990, i n the amount of $9,681,218.O0.
The contract has been completed in substantial
conformance with the plans and specifications approved by the City Council.
The original contract completion date was October 3. 1991, however. this was
extended to November 8. 1991 with the approval of Change Order #6. Change Order #9.
included on this agenda, extends the completion date to December 10. 1991. The
approved extensions were due to required major repairs to the existing digester
covers and modifications to the electrical and instrumentation facilities. The
actual con,'lletion date was April 30. 1992.
The major reason the contract was not completed on time was due to both the
electrical subcontractor and the instrumentation subcontractor going bankrupt.
However. Alder Engineering did everything in their power to keep the workers of the
subcontractors on our job during the bankruptcy procedures. This included paying
cash for the subcontractors' material and paying their workers direct. There is a
$250 per day liquidated damage amount included in the contract. Change Order #9
includes a credit to the City of $35,500 for liquidated damages.
The final contract price is $10,140,096 (4.7% over original contract amount).
However, of the total change order amount of 5459,623, $314,209 was for HVAC system
improvements am repairs to the two existing digester lids. At the time of the
contract award i t was known that HVAC system improvements and digester I i d repairs
would be additional costs. Therefore, unaccountable change orders only amounted to
1.5% of the original contract amount. For an expansion of an exisiting treatment
plant facility, this is an extremely
low change order amount. a [feelstrongly that
this can be contributed to t�roughness our plant personnel and the Electric
Utility Department's electricians did in reviewing the contract drawings.

The increased cost is mainly due to the following major change ordor items:
repairing existing floating covers on Digester #1 and Digester #2, replacing HVAC
system in existing control building, additional asphalt paving. adding additional
pipe and valving supports. providing additional instrumentation. modifying locker
rooms (handicap requirements and additional tile work), improving drainage and
curbing around existing parking area, upgrading concrete wall finishes, repairing
deterioration of headworks influent distribution box, replacing deteriorated steel
doors and window frames on headworks building. expanding capacity of PLC's
(programmable logic controllers). replacing deteriorated insulated steel hot water
lines to digester, and removing sludge from Sludge Lagoon #1,
This was Alder Engineering's first project in California. I can say, without
hesitation, that they performed quality work and the project was run in an organized
and professional manner. The Public Works Department is very pleased with the
construction that took place under this contract. Black & Veatch must also be
co. -mended for their work and especially for the contract administration/inspection
performed by Mr. Miller.
