SUBJECT: CONSIDERATION OF AN AWARD OF CONTRACT TO SANCON
ENGINEERING, INC. FOR THE 2014 SEWER LINING PROJECT, PW
2014-07 -
DATE: MARCH 25, 2014
RECOMMENDATION:
It is recommended the City Council:
1. Award a contract for the 2014 Sewer Lining Project to Sancon Engineering, Inc.
in the amount of $59,416;
2. Authorize the City Manager to approve change orders for 10% of the contract
amount, $5,942 for unanticipated costs during the construction phase of the
project (total construction costs = $59,416 + $5,942 = $65,358); and -
3. Direct the City Clerk to file a Notice of Exemption.
IMPACT ON FINANCIAL AND PERSONNEL RESOURCES:
The FY 2013/14 Capital Improvement Program includes $153,000 for the subject
project. The lowest responsive bid of $59,416 is well below the Engineer's estimate of
$88,500.
BACKGROUND:
The project scope of work involves the rehabilitation of approximately 1384 linear feet of
failing sewer pipe along Le Point Street and Crown Terrace using the Cured-In-Place
Pipe (CIPP) technology. This "trenchless" method allows the pipe to be rehabilitated in
place without having to perform excavation and pipe replacement. The CIPP is a
jointless, seamless, pipe-within-a-pipe, consisting of a resin-impregnated flexible tube.
The flexible tube is inserted and pulled through the existing pipe from manholes and is
then cured, using either hot water under hydrostatic pressure or steam pressure, to
expand the tube to tightly bond with the interior of the existing pipe.

CITY COUNCIL
CONSIDERATION OF AN AWARD OF CONTRACT TO SANCON ENGINEERING, INC. FOR
CONSTRUCTION OF THE 2014 SEWER LINING PROJECT PW 2014-07
MARCH 25, 2014
PAGE2
The City has successfully performed projects using the CIPP method along segments of
East Branch Street and Crown Hill. This particular project is being performed as part of
Project A-1 "Trenchless Sewer Rehabilitation with Point Repairs" identified in the
Wasterwater Master Plan, adopted by Council in January, 2013.
ANALYSIS OF ISSUES:
On March 13, 2014, three bids were opened for the 2014 Sewer Lining Project. The
lowest bid, from Sancon Engineering, Inc. was in the amount of $59,416. Staff has
determined the bid to be responsive and recommends the award of a construction
contract to Sancen Engineering, Inc. Staff anticipates the work starting in late-May with
a 30 calendar day time duration.
ALTERNATIVES:
The following alternatives are provided for the Council's consideration:
1. Approve staff's recommendation to award a construction contract to Sancon
Engineering, Inc. for the 2014 Sewer Lining Project;
2. Do not award a construction contract for the project; or
3. Provide direction to staff.
ADVANTAGES:
The technology allows rehabilitation of failing sewer mains in place without having to
resort to costly excavation. The method is not only more cost effective; it also prevents
degradation of the roadway structural integrity that inevitably follows the traditional
trench and replace method.
DISADVANTAGES:
The majority of the work will be performed at night to take advantage of low sewer flows
within residential neighborhoods.
ENVIRONMENTAL REVIEW:
The project is categorically exempt from CEQA pursuant to Section 15301 (b ).
PUBLIC NOTIFICATION AND COMMENTS:
The agenda was posted at City Hall on Thursday, March 13, 2014. The agenda and
staff report was posted on the City's website on Friday, March 14, 2014. No public
comments were received as of the time of preparation of this report.
