TO: CITY COUNCIL
FROM: GEOFF ENGLISH, PUBLIC WORKS DIRECTOR
BY: JILL MCPEEK, CAPITAL IMPROVEMENT PROJECT MANAGER
SUBJECT: CONSIDERATION OF AN AWARD OF CONTRACT TO INSITUFORM
TECHNOLOGIES, LLC FOR THE ARROYO GRANDE CREEK SEWER
REHABILITATION PROJECT, PW 2016-05
DATE: AUGUST 23, 2016
RECOMMENDATION:
It is recommended the City Council:
1. Award a contract for the Arroyo Grande Creek Sewer Rehabilitation project to
Insituform Technologies, LLC in the amount of $145,331;
2. Authorize the Acting City Manager to approve change orders for 10% of the
contract amount, $14,533 for unanticipated costs during the construction phase
of the project (total construction costs = $145,331 + $14,533 = $159,864);
3. Direct the City Clerk to file a Notice of Exemption.
IMPACT ON FINANCIAL AND PERSONNEL RESOURCES:
An allocation of $246,900 is available in the adopted FY 2015-16/FY 2016-17 Capital
Improvement Program budget for the project. The total cost of the project including
design, construction inspection and contingencies is estimated at $184,602.
BACKGROUND:
The project scope of work involves the rehabilitation of approximately 2,435 linear feet
of sewer pipe along Arroyo Grande creek east of Clarence Avenue to Paulding Circle,
and for a section of pipe between North Mason Street and Crown Terrace, north of East
Branch Street. The pipe will be rehabilitated using a cured in place pipe (CIPP) method.
CIPP is a trenchless (or no-dig) process where a 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. This trenchless method allows the pipe to be rehabilitated in
place without having to perform excavation and pipe replacement.

Rehabilitation project. The lowest bid, from Insituform Technologies, LLC, was in the
amount of $145,331. The bid has been determined to be responsive and Insituform
Technologies, LLC to be a responsible bidder. It is recommended to award a
construction contract to Insituform Technologies, LLC. Insituform Technologies
completed the City’s last lining project on time and under budget.
The contract time is 45 working days. Work is expected to be accomplished between
September and November 2016.

1. Award a construction contract to Insituform Technologies, LLC for the Arroyo
Grande Creek Sewer Rehabilitation project;

ADVANTAGES:
