Administrator Sitcw•orks Construction By ai Deputy I SUBJECT: RATIFY the decision of the General Manager of the Blackhawk Geologic Hazard Abatement District to issue contract change orders to Siteworks Construction, Inc., Danville area. (WO #5147) DATE: September 11, 2001 PAGE: -2- Ill.. Reasons for Recommendation and Background: A contract was awarded to Siteworks Construction, Inc. on December 13, 2000 in the amount of $60,038.08 to repair a landslide that occurred on the southwest side of the hill below 256 Red Pine Court, as well as a concrete ditch in the vicinity that was also deficient. The decision to award this contract was ratified by the Board of Directors of the Blackhawk GHAD on February 6,2001. Prior to the Contractor being able to mobilize to the repair site, the main access route was compromised, requiring the Contractor to develop alternative access to the work area. Additionally, the Contractor was asked to provide pumping equipment to accommodate the additional pumping distance,and make provisions for demolition and restoration of existing facilities and vegetation affected to gain access. These changes resulted in significantly more cost to the Contractor than was originally anticipated at the time of award of the contract. As a result,it was necessary to provide the Contractor with Contract Change Orders in the amount of$9,707.64 to cover the increased costs. Consequences of Negative Action: The work on this project has been completed. Board action is necessary to allow the General Manager to process payment to the Contractor regarding the above-mentioned work.
