This change order would add $326,000 to the Dublin Boulevard
widening project, Contract No. 95-01, and would serve as the 1996-
97 Street Overlay Program. Sufficient funding is included in the
1996-97 Street Maintenance Budget and the Annual Street Overlay

Deleting the slurry seal item from the Dublin Boulevard_.Widening
project will save about $30,000 to that project.
Upon completion of the work, a budget transfer will be made
between the CIP project and the operating budget to match the actual
costs. Caltrans has approved the use of SB300 funds for this street
overlay work and has approved the use of the change order process
to have the work performed.
A breakdown of the change order costs is sho~rn on Exhibit 2.

DESCRIPTION: On July 25, 1995, the City Council awarded a contract to Redgwick
Construction of Hayward, California, to widen Dublin Boulevard from four to six lanes between Donlon
Way and Village Parkway. As awarded, the project called for placement ora Slurry Seal surface prior '-
the final restriping of the new traffic lanes. However, while the slurry seal will give the street a unifc
color and coating, it will not cover the imperfections in the street surface caused by the piecemeal paving
and underground utility trenching. For this reason, Staff is recommending to overlay Dublin Blvd. and
thereby provide a smooth uniform surface to complement the other new work along the street.
The 1996-97 Street Operating and Capital Improvement Program Budget provides $330,600 for the
asphalt concrete overlay and repair of residential streets. Staff is proposing that the 1996-97 Overlay
Program be used to resurface Dublin Blvd. through the Dublin Blvd. Widening project limits.
To complete the budgeted repair and overlay work, three additional residential streets are proposed for
repair and overlay and are listed as follows:
Tory Way, from Prince Drive to King Way
lone Way, from Brighton Drive to Newcastle Lane
Newcastle Lane, from lone Way to Brighton Drive
A contract change order has been negotiated with Redgwick Construction for the Dublin Boulevard
Widening project, as well as the three residential streets. Preparatory work for the overlay, including
pavement repair and pavement grinding along the curb, can be accomplished during the normal work day
schedule. The actual paving, including placement of pavement reinforcing fabric, will be scheduled as a
night-time operation to minimize the disruption of traffic. ..
The Change Order is being referred to the City Council for approval, as it exceeds the City Manager's
authority to approve.
