COUNCIL COMMUNICATION
M
AGENDATITLE: Adopt Resolution Authorizing City Managerto Negotiate Change Orders up
to $7,750,000 with Western Water Constructors, Inc., of Santa Rosa, for
Emergency Repair of Domestic Outfall Sewer Pipeline
MEETING DATE: October 17,2007
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Adopt a resolution declaring a local emergency for the Domestic
Outfall Sewer Pipeline; dispensing the City's bidding requirements in
accordancewith LMC §3.20.070; and authorizing the City Manager
to negotiate change orders of up to $7,750,000 with Western Water
Constructors, Inc., of Santa Rosa, for the emergency repair of the Domestic Outfall Sewer Pipeline.
BACKGROUND INFORMATION: The City of Lodi's DomesticOutfall Sewer Pipeline (pipeline)was
constructed in the late 1960's of unlined reinforced concrete pipe. It
conveys an average of 6.5 million gallons of wastewater per day
from the City of Lodi to the White Slough Water Pollution Control
Facility (WSWPCF) that is located approximately five (5) miles to the southwest of town.
Certain locations of the pipeline condition were evaluated numerous times since its original construction,
however, the entire alignmentwas not assessed until recently. The most recent assessment revealed
that portions are severely corroded and the pipeline is in need of rehabilitation. In response, the City has
been repairing areas of concern and planning a pipeline repair project scheduled to commence in the
spring of 2008.
However, a recent event highlights the need to perform the repairs immediately. A construction worker
replacing a corroded segment underThornton Road fell through another unstable section of the pipeline.
Thankfully, the worker was not injured (the pipe was empty at the time as flows were being diverted to
conduct the repairs). The event, however, clearly shows the potential risks associated with not taking
immediate action. Staff has advised property owners along the alignment of the situation and has
recommended safeguards for them to observe until further notice.
In response to this urgent situation and to expedite the pipeline repair, staff recommends the Council
authorize the City Manager to negotiate a change order with Western Water Constructors, Inc., (WWC).
WWC is currently under contract with the City to construct the WSWPCF Phase 3 Improvements. The
company has a long-standing relationshipwith the City, in addition to Phase 3, as it has successfully
completed the WSWPCF Phase 1 and Phase 2 Improvements. All three project phases were
competitively bid in accordance with State Public Contract Code and Phase 1 and 2 were completed on
time and on budget. The company continues to exhibit fair, very cost effective, and responsive
management practices while delivering top quality construction work during the current Phase 3
improvements. Their success is in part contributed to their familiarity with the City's facilities and

infrastructure operation. In addition, the company has already performed spot repairs in the pipeline and
has a good knowledge of local conditions.
Staff is confident that by executing a change order with WWC for the pipeline work, the City will enjoy a
very competitive price for the work while taking the most expeditious path toward completing the repair
and eliminating the risks associated with a pipeline susceptible to collapse.
FISCAL IMPACT: The Domestic Outfall Sewer Pipeline has reliably served the City for over
40 years, which is the typical life expectancy of non -lined reinforced
concrete pipe. Though it is recommendedthe City's bidding requirements
be dispensed, the cost of the repairs will likely be equal to or less than if the
projectwas competitively bid due to the City's good relationship with the contractor. The total cost of the
repair is estimated at $7,750,000. By repairing the pipeline, the City will mitigate its current risk of
exposure to loss of life and/or property damage.
FUNDING AVAILABLE: The projectwill be funded by proceedsfrom proposed 2007 Certificates of
Participation scheduled to be sold in late November of this year.
