AGENDA TITLE: Accept Improvements Under Contractfor Wastewater Infrastructure Replacement
Program (Project No. 4) Project
MEETING DATE: November 18, 2009
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Accept the improvements underthe contract for the Wastewater
Infrastructure Replacement Program (Project No. 4) Project.
BACKGROUND INFORMATION: The contract for this project was awarded to Pi penology, Inc., of
Rocklin, on February 18, 2009, in the amount of $845,260.
The Wastewater Improvement Program is intended to systematically replace and, where needed, upgrade
existing wastewater infrastructure. The older wastewater pipelines are mostly constructed of terra-cotta or
concrete pipe. The majority of these pipes are in need of rehabilitation and/or replacement. Project No. 4 is
the fourth project scheduled in this program.
Once all phases of the program are completed, the improvements will enhance the level of service associated
with the wastewater system by increasing reliability, eliminating pipe joint leaks, and decreasing maintenance
costs. As with Project Nos. 1 and 2, which were located in the same general area east of Stockton Street and
north of Kettleman Lane, and Project No. 3, which was located in the greater Downtown area, trenchless
methods of rehabilitation were used for Project No. 4 to minimize both surface disruption and costs.
This project, similar to Project No. 3, was for wastewater rehabilitation only. Replacement of water lines,
upgrading water services, and installing water meters in this area will follow as a separate project.
Project No. 4 included in-place (trenchless) rehabilitation of approximately 14,385 linear feet (2.7 miles) of
6 -inch diameter wastewater main, the rehabilitation of approximately 58 manholes, and the reconnectionof
600 wastewater laterals.
The final contract price was $974,389. The difference between the contract amount and the final contract price
was due to Contract Change Order No. 1 and adjustments to the original contract quantities. Contract Change
Order No. 1 added 11 point -repair locations to the contract, added the installation of three 24 -inch risers and
paid for the removal of 46 protruding laterals.
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 paymentsfrom the
prime contractor in the event of a payment dispute.
FISCAL IMPACT: Completion of this project will reduce future maintenance costs and increase
the performance and reliability of the wastewater system. There will be no
additional maintenance costs associated with the project.
FUNDING AVAILABLE: Wastewater Fund (171679) $990,000
