CITY OF SAN BERNARDINO - REQUEST FOR COUNCIL ACTION
Staff Report
Subject:
Authorize the execution of Change Order No. One to contract with Nikola Construction Corporation,
d.b.a. Nikola Corporation, for sewer improvements on Court Street between "E" Street and "0" Street
per Plan No. 10561, and authorize the Finance Director to amend the FY 02/03 Budget.
Back~round:
Bids for sewer improvements on Court Street between "E" Street and "0" Street per Plan No. 10561
'" ere received on December 3, 2002, and a contract in the amount of $56,562.80 was awarded to the
IGwest bidder, Nikola Corporation on February 18, 2003.
During the construction of this project, certain changes were necessary to assure a satisfactory finished
project. These changes are as follows:
1. During the design process the sewer main in Court Street was video inspected and two sags were
found in the existing line approximately mid-block between "E" Street and "0" Street. Staff
designed a replacement sewer main to eliminate the sags. After start of construction, Public
Services performed some additional video inspection and found another low spot in the existing line
near Molly's Cafe. The newly discovered low spot was downstream of our construction project;
therefore, it was necessary to extend the sewer an additional 123 feet easterly to provide positive
flow to a manhole in "0" Street. This change was necessary to correct the reverse grade condition
that was discovered by the second video inspection. Staff directed the contractor to proceed with the
extension on an extra work basis to avoid delaying the contractor and to minimize the possibility
offensive odors would still exist after completion of construction.
2. Delays and additional potholing resulted in extra cost to the contractor due to conflicts with
unanticipated subsurface conditions. The primary cause of the conflicts was underground utilities
lines that were not identified during the utility search which was conducted prior to bidding.
Additionally, concrete pavement was encountered underneath the asphalt pavement resulting in
additional cost of the contractor to break through the concrete. These problems are commonly
encountered while excavating in downtown streets and are difficult to identify during the design
process.
This change order, in the amount of $50,565.27, represents a reasonable cost for the items of extra
work identified in the attached Change Order No. I.
This change order exceeds 25 % of the contract amount, therefore, in accordance with Section 3-2.1
"Changes initiated by the Agency" of the Standard Specifications, changes exceeding 25% of the
contract amount "shall be by written Supplemental Agreement between the Contractor and Agency,
unless both parties agree to proceed with the change by Change Order". The Contractor's signature on
the attached change order indicates its acceptance of the changes and the prices indicated.

Staff Report
Financial Impact:
There is approximately $7,500 currently available for this project (account 245-365-5504-7314). The
cost of this change order is estimated to be approximately $56,565, which is $43,065 more than
available. A budget amendment of $50,000 is requested to cover the remaining $43,065 needed for this
change order. The remaining $6,935 will cover minor future project costs such as an additional
anticipated change order of less than $5,000 and inspection and testing costs. The $50,000 will be
appropriated from the Sewer Line Construction Fund balance.
Recommendation:
I. Authorize the Director of Finance to amend the FY 02/03 budget by appropriating $50,000
from the Sewer Line Construction Fund's available fund balance to account number 245-365-
5504-7314 (Court Street Sewer Main Replacement from "E" Street to "D" Street).
2. Authorize execution of Change Order No. One in the amount of $50,565.27 to contract with
Nikola Construction Corporation, d.b.a. Nikola Corporation for sewer improvements on Court
Street between "E" Street and "D" Street per Plan No. 10561.

GENTLEMEN:
You are hereby compensated for performing the additional work as follows:
ITEM NO: DESCRIPTION OF CHANGE COST
Furnish all labor, equipment and material to extend the
1-1 sewer an additional 123 feet easterly in Court Street to $ 21,962.75
provide positive flow to a manhole in "0" Street per
attached nronosal from contractor received 04/10/03.
Delay and extra cost encountered due to unknown subsurface
conditions encountered while trenching for the new sewer
1-2 line per attached letter from contractor dated 04/14/03, and $ 28,602.52
attached Extra Work reports dated 03/18/03 through
04/09/03.
TOTAL COST CCO #1 $ 50,565.27
JUSTIFICATION:
Item No. 1-1
The purpose of this project was to remove a sag in an existing sewer main in Court Street. After start
of construction another low spot was discovered in the existing sewer system adjacent to Molly's Cafe.
That portion of the sewer was not indicated on plans to be replaced as part of this contract. After
reviewing the new information, staff concluded that in order to minimize the possibility of bad odors
the new sewer needed to be extended 123 feet east in Court Street to connect to an existing sewer
manhole in "D" Street.
We feel this price is fair and reasonable for the work involved.
Change Order No. One
Sewer Improvements on Court Street between "E" Street and "D" Street Per Plan No 10561.
Under the provisions of Section 3-2.2.3 "Agreed Prices" of the Standard Specifications, where
modifications are made to items not covered by Contract unit prices, payment for the changes may be
determined by agreement between the contractor and Agency. We feel the quoted price for this work is
fair and reasonable.
Item No. 1-2
After start of excavation for the new sewer, the contractor encountered subsurface conditions that had
not been discovered during the design process. These subsurface conditions included unknown
underground utilities that were not identified during the utility search conducted prior to receipt of bids.
In several instances the unknown utility encountered could not be readily identified. The contractor
was required to stand-by while staff contacted the various utilities to assist in identification and
disposition of the unknown utility. This resulted in delay cost and extra work costs to the contractor for
which he is entitled to additional compensation under the provisions of Section 5-5 "Delays" of the
Standard Specifications.
The cost of this portion of the work was determined by tracking time and materials. The details of this
extra cost is shown in the attached letter from contractor dated 04/14/03, and attached Extra Work
reports dated 03/18/03 through 04/09/03.
Under the provisions of Section 3-3 "Extra Work" of the Standard Specifications, where the price of
extra work cannot be agreed upon, the Agency will pay for the extra work based on the accumulation of
actual costs incurred by the Contractor. This method of compensating the Contractor for Extra Work is
commonly known as Time and Materials (T & M).
SUMMARY OF CONTRACT COSTS
The estimated revised contract cost is as follows:
Original bid amount ...... ............................................ ........................ $56,562.80
Contract change order no. one ._.............................. ........................... 50,565.27
Revised Construction Contract cost... .......................... ..................... $107,128.07
Additional time to complete Contract due to this Change Order ...............15 Working Days
The amount of this change order is 89.4 % of the original contract amount and the total amount of all
change orders to date is $50,565.27. The total amount of all change orders to date exceeds the
contingency amount approved by the Mayor and Common Council as part of the award of the contract
on February 18, 2003, therefore, a supplemental budget appropriation will be necessary.
The changes to the work contemplated by this Change Order exceed 25 % of the original contract
amount. The Contractor's signature on this document indicates his acceptance of this modification to
the contract as a change order rather than a supplemental Agreement as provided by Section 3-2.1
