DATE: MARCH 24, 2015
RECOMMENDATION:
It is recommended the City Council:
AN AWARD OF CONTRACT TO INSITUFORM
FOR THE 2015 SEWER LINING PROJECT, PW
1. Award a contract for the 2015 Sewer Lining Project to Insituform Technologies,
Inc. in the amount of $119,577;
2. Authorize the interim City Manager to approve change orders up to 10% of the
contract amount, $11,958, for unanticipated costs during the construction phase
of the project (total construction costs = $119,577 + $11,958 = $131,535); and
3. Direct the City Clerk to file a Notice of Exemption.
IMPACT ON FINANCIAL AND PERSONNEL RESOURCES:
The FY 2014/15 Capital Improvement Program includes $185,500 for the subject
project. The lowest responsive bid of $119,577 is below the Engineer's estimate of
$130,000.
BACKGROUND:
The project scope of work involves the rehabilitation of approximately 2,660 linear feet
of failing sewer pipe along segments of East Branch Street, Eman Court to Newman
Drive, and the Pike, 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 INSITUFORM TECHNOLOGIES, INC.
FOR CONSTRUCTION OF THE 2015 SEWER LINING PROJECT PW 2015 -04
MARCH 24, 2015
PAGE 2
The work includes components of Project A -1 "Trenchless Sewer Rehabilitation with
Point Repairs" and Project A -2 "Trenchless Sewer Rehabilitation ", identified in the
Wastewater Master Plan adopted by Council in January, 2013. The City has
successfully performed projects using the CIPP method along segments of East Branch
Street, Crown Hill, Le Point Street and Crown Terrace.
ANALYSIS OF ISSUES:
On March 10, 2015, two bids were opened for the 2015 Sewer Lining Project. The
lowest bid, from Insituform Technologies, Inc. was in the amount of $119,577. Staff
has determined the bid to be responsive and recommends the award of a construction
contract to Insituform Technologies, 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 staffs recommendation to award a construction contract to Insituform
Technologies, Inc. for the 2015 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:
Some work may be performed at night to take advantage of low sewer flows within
residential neighborhoods. Public Works will notify all affected residents prior to
performance of nighttime operations.
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 12, 2015. The agenda and
staff report was posted on the City's website on Friday, March 13, 2015. No public
comments were received as of the time of preparation of this report.
