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.

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.
