CITY OF SAN BERNARDINO - REQUEST FOR COUNCIL ACTION
STAFF REPORT
The plans for improvement of the access roads and parking
facilities for the San Bernardino International Airport direct
that the existing 10-inch water line in Leland Norton Drive be
abandoned. This action is due to the fact that this water line
is steel and has been in operation for about 50 years, which is
the normal service life.
A 12-inch new water main is being installed under this
project to replace the one being abandoned. There are several
laterals to the existing line, varying from 4 inches to 10 inches
in diameter, that are to be connected to the new water main.
A storm drain is also being installed in Leland Norton
Drive under this contract. During construction of this new water
line, it was discovered that the new storm drain was at approxi-
mately the same elevation. The storm drain constitutes an
obstruction to connection of the water laterals. This situation
required the Contractor to route the laterals over the storm
drain, which entailed additional fillings and labor.
The plans indicate that the laterals are at right angles
to the new main. However, during construction, it was discovered
that many of the laterals actually were parallel to the main.
Extensive exploratory work was necessitated to determine what the
lateral served and which ones had to be connected to the new
water main in order to maintain service to facilities that are in
use. This effort was complicated by the fact that a considerable
number of the gate valves were inoperative and in many cases
buried.
The Contractor performed the extra work involved in
connecting the laterals on a time and materials basis, in accor-
dance with Section 3 of the Standard Specifications. Change
Order No. 6 will authorize payment of $37 , 048 . 87 to the
Contractor for this extra work.
Funds to finance the additional cost due to Change Order
No. 6 will be provided from the following sources :
Economic Development Administration Grant - 75%
Inland Valley Development Agency - 25%
No City funds will be used to finance any portion of the
cost of this change order. The total estimated project cost,
based upon the actual low bid price, included an amount of
$281 , 686 for contingencies, which can be used to finance the cost
of this change order.
All costs incurred for this extra work will be charged to
Account No. 242-362-5504-7038 , and billed to the EDA grant and
IVDA.
We recommend that Change Order No. 6 be approved.

CONTRACT CHANGE ORDER
CHANGE ORDER NO. 6
DATE: 7/29/96
Agreement Date: 2/12/96
NAME OF PROJECT: PASSENGER TERMINAL ACCESS ROADS AND PARKING
FACILITIES_; SAN BERNARDINO INTERNATIONAL AIRPORT
OWNER: CITY OF SAN BERNARDINO
CONTRACTOR: RIVERSIDE CONSTRUCTION
The following extra work is to be performed, as directed by the
Resident Engineer, and the following changes are hereby made to the
CONTRACT DOCUMENTS:
(1) Installation of additional pipe bends and the relocation of
existing water mainlines at 6-locations where there is a conflict
with the existing storm drain pipe and other utilities, on a time
and material basis, at a total cost of $ 12,311. 17.
(2) Locate the existing water mainline at 8-locations where the
existing water pipe is not at the location indicated on the plans,
remove additional concrete encasements, and additional exploratory
trenching, on a time and material basis, at a total cost of
$ 24,737 .70.
JUSTIFICATION:
During the installation of the new water mainline services, there
were 4-existing water services laterals not identified on the plans
that had to be tied into the new 12-inch mainline. Additionally, in
order to tie into the existing water mainline services on the east
side of Norton Way, it was necessary to relocate the water lines up
and over the existing storm drain. This conflict was not indicated
on the plans and the existing waterlines were at an elevation that
was in direct conflict with the new storm drain.
Most of the existing water laterals were not at the location
identified on the plans. This required the contractor to perform
extensive investigation to find the existing water lines and to
verify that they were actually the ones that were to be tied into.
The water laterals were found to be as much as 10-feet from the
location indicated on the plans and running in different directions
than that indicated on the plan. This work was performed on a time
and material basis. Also additional abandoned concrete encasements
and vaults not indicated on the plans were discovered that needed
to be removed.
