FINANCIAL STATEMENT: See Below
DESCRIPTION:
In April, 1988, the City Council awarded Contract 88-4 to Les
McDonald Construction Company. This contract combined the Annual Street
Overlay and Repair Program and the Dougherty Road Bike Path. The street
repair which was undertaken as part of this contract included those streets
which are overlaid and slurry sealed.
In the development of the Fiscal Year 1988-89 Annual Budget,
Staff anticipated that the work included in this contract would be completed
prior to the end of Fiscal Year 1987-88, and therefore, no funds were
budgeted in Fiscal Year 1988-89 to complete the project. As indicated in
the memorandum from the Public Works Inspector to the City Manager dated
October 3, 1988 (see attached), numerous problems were encountered during
the course of construction which caused the project to overlap into Fiscal
Year 1988-89. These problems also necessitated two change orders (see
attached) totaling $20,477.87 and $33,256.10 respectively. These change
orders involved additional street repair associated with more extensive
street failures than anticipated on Bedford Way, Canterbury Lane, and
Brighton Drive. These streets had serious subgrade problems which had last
been skin-patched and slurry sealed before incorporation. The Public Works
Director authorized additional repair in these areas in the field. In
addition to time required to complete this additional work, the contractor
took more time than was allowed under the contract and the change orders and
was, therefore, assessed liquidated damages totaling $4,500.
Despite the problems encountered with this contract, the actual
project costs were well under the total budget established for these
projects in Fiscal Year 1987-88 as shown below.

CITY OF DUBLIN
MEMORANDUM
Date:
October 3, 1988
To: City Manager
From:
Public Works Inspector
Subject: Attached Change Orders for Contract 88-4
The annual street overlay project includes digging out and repairing
the failed areas in both the streets to be overlaid with asphalt concrete and
those which receive a slurry seal coat. Identification of failed areas is
often made difficult by previous attempts to cover the failures with slurry
seals or asphalt skin patches, a commoh practice of Alameda County
maintenance. During the recent overlay project, it became evident, as the
marked out areas were exposed, that the failures were more extensive than
originally surveyed. The streets which required almost total rehabilitation
were Canterbury, Bedford, and Brighton. Brighton Drive also collmpsed in
five locations in the parking lanes during the paving operation. The cost to
repair these areas required an additional $33,295.10. This amount covers
extended bid item amounts to make the extra repairs.
Bid item quantities also had to be adjusted because Regional Street was
pulled off the overlay at the last minute due to a time conflict for the
installation of E1 Pollo Asado's gas line. The overlay was extended on
Tamarack to Elgin Lane, thereby changing quantities in striping and monuments
in particular. An extra cost was also incurred when the grinder hit a buried
monument on Brighton Drive and had to be repaired.
