Synopsis of Previous Council Action:
07-05-11 The Mayor and Common Council adopted the FY 2011-12 to FY 2015-16 Capital
Improvement Program (5-year CIP).
04/16/12 The Mayor and Common Council awarded a contract to Nikola Corporation for
Sewer Improvements on "H" Street and the Adjacent Alleys between 17th Street
and Highland Avenue,per Plan No. 12621 (SW11-002).
Background:
On April 16, 2012, the Mayor and Common Council awarded a contract to Nikola Corporation

2522
for the replacement of approximately 7,600 lineal feet of sewer line in "H" Street between 17th
Street and Highland Avenue. The contract included replacement of existing sewer mainline and
manholes, as well as some repairs to sidewalk, curb and gutter, driveway approaches and street
surfaces impacted by the pipe construction.
A Notice to Proceed was issued to the contractor, and work was scheduled to begin Monday
April 30, 2012. The following day, staff was contacted by the contractor that several areas
marked by Southern California Gas Company appeared to be in direct conflict with the City's
sewer line replacements. These conflicting facilities were recently installed by the Gas Company
in a location that was unexpected.
On May 7, the Gas Company agreed to meet with staff and Nikola on-site to review and
investigate these conflicts and to help determine what could be done to minimize further
construction delays on this project.
Nikola was directed to continue with construction in "H" Street, and begin construction in one of
the alleys to determine the extent of the conflicts and the associated additional cost anticipated
for replacement of the mains along all of the alleys. All of the extra costs for this time and
material work have been reflected in this change order. After careful consideration of the gas line
conflicts, it was determined that the best course of action was to eliminate several alley mains
from the contract and deduct their associated cost from the scope of work.
There were additional time delays and impacts to the project from existing storm drain laterals
that were unmarked, and an overly deep 14-inch water main that ran parallel to the proposed
sewer line in "H" Street. Several sewer manholes were changed from a standard type manhole to
a drop sewer manhole to avoid conflicts with the aforementioned water main. Additional
changes to the scope of work include additional potholing,pavement repairs, and changes to unit
pricing allowed by the contract as a result of deducting the alley work.
The contractor has been paid $640,300 for all work completed to date, with $33,700.00 held in
retention. The net effect of this Change Order No. 1 will result in an additional $19,897.23
(2.95%) due the contractor,which is under the approved contingency amount for this project.
