STAFF REPORT
Subject:
Authorization to execute Change Order No. Two to contract with Bonadiman-McCain, Inc. for
removal of an abandoned 16" steel water line in Mt. V ernon Ave. from Base Line St. to 16th St.
Background:
On August 21, 2000, the Mayor and Common Council awarded a contract to Bonadiman-
McCain, Inc. in the amount of $550,435.00 for installation of storm drain improvements in Mt.
V ernon Avenue from Base Line Street to 16th Street.
On December II, 2000, Contract Change Order No. One in the net amount of $4,430.14 for the
removal of an existing manhole structure was approved by the City Administrator.
During construction, it was found that an abandoned 16" steel water line existed approximately 5
feet deep and immediately above the location of the new storm drain. Given traffic control
constraints in the project, other existing utilities in the road, and the potential for settlement due
to the abandoned water line, it was deemed necessary to direct the contractor to remove the
abandoned water line. Under Section 3-4 "Changed Conditions" of the Standard Specifications,
the contractor is allowed to recover additional costs due to "subsurface or latent physical
conditions differing materially from those represented in the contract."
In addition, the City's Water Department has agreed to reimburse the Capital Improvement
Program account for 50% of this cost because the water line removal was considered beneficial
to both Departments.
The changes are described in the attached change order.
The revised contract cost is as follows:
Original Bid Amount. ......................................... .......... ................. ............... .$550,435 .00
Increase due to CCO#1 - Remove existing manhole structure ..................... $4,430.14
Increase due to CCO #2 - Remove abandoned 16" water line..,................... $31,530.53
Revised Contract Amount............................................................................$586,395.67
Additional time to complete Contract due to Change Order-I 8 Working Days

CONTRACT CHANGE ORDER NO. TWO

PROJECT: MT VERNON STORM DRAIN IMPROVEMENTS

San Bernardino, Ca. 92408
GENTLEMEN:
You are hereby compensated for performing the additional work as follows:
Description of Chanl!e Cost
Removal of abandoned 16" steel water line on a Time and Materials $ 31,530.53
Basis
TOTAL CHANGE ORDER COST $ 31,530.53
JUSTIFICATION:
While the contractor was excavating in Mt. Vernon Avenue for the installation of a new storm
drain, an abandoned 16" steel water line was encountered. The water line was about 5' deep and
interfered with excavation for the storm drain. It was apparent that the water line would have to
be removed to allow installation of the storm drain.
Staff checked with the City Water Department and determined that the water line was probably
abandoned in the 1950's when it was replaced by a larger water line. It was also determined that
the abandoned water line more than likely extended the full length of the storm drain project
from Base Line Street to 16th Street. It was apparent that the abandoned water line would have to
be removed the full length of the project.
In addition, administrative changes have been implemented in the utility agency review process
with respect to abandoned water lines to minimize the possibility of similar future conflicts.

Under the provisions of Section 3-4 "Changed Conditions" of the Standard Specifications, the
contractor is entitled to a change order to adjust compensation when subsurface conditions not
shown on plans are encountered,
The additional work necessary to remove the abandoned 16" steel water line is categorized as
"Extra Work" under the provisions of Section 3-3 of the Standard Specifications. Based on that
provision, staff authorized the contractor to proceed with removal of the abandoned water line on
a Time and Materials (T & M) basis. T & M "Extra Work" reports covering the period
November 19,2000 through January 3, 2001, prepared by the contractor and verified by the City
Construction Inspector, are attached and made a part of this change order.

INTEROFFICE MEMORANDUM
TO: Raymond A. Casey, City Engineer
FROM: Bernard C. Kersey, General Manager/Water Department
SUBJECT: ABANDONED 16" STEEL WATER LINE IN MT. VERNON AVENUE
FROM BASELINE STREET TO 16TH STREET
DATE: January 10, 2001
COPIES:
Bill Woolard, Interim Director
Services; Michael W. Grubbs, Field
Bryden, Director, Water utilities
of Development
Engineer; Bill
I have reviewed the information set forth in your memo dated
December 14, 2000 concerning the abandoned 16" water line that
was discovered when your contractor was excavating for the Mt.
Vernon Storm Drain project.
When the department responded to the utility notice letter sent
during the design phase of the project, we identified all known
facilities that we had in the area. It was not known during that
time that there was an abandoned 16" line in Mt. Vernon. When
we were notified of the situation, staff went back through
thirty years of records to see if we could determine when the
line was abandoned in place, and found no information. We are
changing our procedures so that our base maps will reflect
abandoned lines when they occur to avoid this situation.
Without having someone in the Engineering Section that was here
more than thirty years ago, there is no way we would have been
able to provide information to Public Works about the abandoned
line. Abandonment of facilities in place is the typical
procedure for water and sewer lines.
I have received a copy of the change order for the additional
work of removing the abandoned 16" line for $31,530.53 that will
be submitted to the Mayor and Common Council for approval. The
department is willing to cost share approximately 50% of the
change order value, or $15,765.27.
