The project is funded through Traffic Impact Fees (300) for City improvements and
General Fund (001) for Dublin San Ramon Services District (DSRSD) improvements.
Improvements costs (plus 7.5% administrative fee) for DSRSD's portion of the project are
being reimbursed by DSRSD back to the General Fund. No budget change is required for
Contract Change Order Nos. 7 and 8 as total of the change orders to date is within the
contingency amount.
Even though the project will still be under budget, the City's policy relating to contract
change orders for capital improvement projects (Resolution No. 18-88) caps the amount of
change orders that the City Manager can approve at 5% of the contract amount.

DESCRIPTION: On February 6, 2001, the City COuncil awarded Contract No. 00-16,
Dublin Boulevard Widening - Dougherty Road to Scarlett Drive. This project widens Dublin BoUlevard
to six lanes from Dougherty Road to Scarlett Drive, including installation of a new traffic signal at the
Dublin BOulevard/Scarlett Drive intersection, and installation of a DSRSD recycled water pipeline. The
project is currently 80% complete.
'Contract Change Order No. 7 (Attachment 1) is requested by DSRSD to perform extra work as part of the
recycled water pipeline installation. The City's contractor, McGuire and Hester, encountered several
utilities shown incorrectly on the plans and is required to make pipeline adjustments to accommodate
existing conditions. The estimated cost increase for furnishing all materials, equipment and labor to.
perform the necessary adjustments is $20,882.10~
Contract Change Order No. 8 (Attachment 2) is requested by the City to perform additional work not
described in the Plans and Specifications for the traffic signal system and street lighting. Conduits will be
added to complete the traffic signal interconnect on Dublin Boulevard to the traffic signal at DeMarcus
Boulevard. This change order also includes placing conduits across Dublin Boulevard (east of Scarlett
Drive) for the future median island construction between Scarlett Drive and DeMarcus Boulevard.
Installing the median irrigation and subdrain conduits prior to resurfacing Dublin Boulevard will eliminate
the need to trench across the new pavement.
Staff has reviewed the change orders and recommends that the City Council approve Contract Change
Order Nos. 7 and 8 in the amounts of $20,882.10 and $14,324.75, respectively.
