AGENDA TITLE: Acce t Improvements Under Contract for the Domestic Outfall Sewer Pipeline
Cond�tion Assessment Project
MEETING DATE: August 1, 2007
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Accept the improvements underthe Domestic Outfall Sewer Pipeline
Condition Assessment Project contract.
BACKGROUND INFORMATION: The project was awarded at the November 16, 2006 Council
meeting to J.F. Pacific Liners, Inc., of Vacaville, CA, in the amount
of $47,494.34.
This project included closed circuit television (CCTV) condition assessment of the Domestic Outfall
Sewer Pipeline between Lower Sacramento Road and the White Slough Water Pollution Control Facility
(WSWPCF). The assessment was the first phase (Phase 1) of multiple phases of work to assess and
rehabilitatethe Domestic Outfall Sewer Pipeline that has been in service for nearly 40 years. This
assessment project revealed that the existing pipeline is showing its decades of use. The interior
concrete walls have eroded to the point where some reinforcement bars are exposed. I n other locations,
the reinforcement cage has fallen from the top of the pipe and is impeding the wastewater flow. The
video inspection also showed locations where the crown of the pipe is completely missing and other
locations where sediment in the pipe flowline prevented the video camera from continuing down the pipe.
Subsequent phases of this projectwill include construction of additional manholes and a diversion
structure and then the actual pipeline rehabilitation. The 2007108 budget has $7,750,000 budgeted for
this rehabilitation work. An update of the project will be given with the next Quarterly Utility Report.
The final contract price is $64,069.34. Contract Change Order No. 1 was issued to J.F. Pacific Liners, Inc.,
in the amount of $16,575.00 to pay for cleaning sections of the outfall pipeline. The cleaning needed to be
done in order to perform the CCTV assessment.
Following acceptance by the City Council, as required by law, the City Engineerwill file a Notice of
Completion with the County Recorder's office. The notice serves to notify vendors and subcontractors
that the project is complete and begins their 30 -day period to file a stop notice requiring the City to
withhold payments from the prime contractor in the event of a payment dispute.
FISCAL IMPACT: Failureto pursuethe rehabilitation portion of this projectwill result in continued
deterioration and eventual failures of the pipe, which would result in sewage
spills, potential fines and response costs.
FUNDING AVAILABLE: Not applicable.
