DESCRIPTION: ConstTuction of the 1-580/Tassajara Road Interchange Improvement project is approximately 95% complete. It is necessary for the City Council to approve three Change Orders for this project as the amount of each of the Change Orders exceeds the $25,000 authorization limit granted to the City Manager. Change Order No. 10 is needed to cover the cost of installation of landscape improvements within Caltrans right-of-way along 1-580 and along the diagonal on-ramp to westbound 1-580 adjacent to the Koll Dublin Corporate Center (Koll). A Condition of Approval for the Koll project was to install this COPIES TO: g:hmiscproj\i-580 Tassajara\project\agst CCO 10,18, 33 Authorization DeSilva Gates Construction ITEM NO. landscaping. At the request of the Koll Development Company, the City entered into an agreement with Koll on November 6, 2001, to install the landscaping improvements on behalf of Koll, as part of the 1-580/Tassajara Road Interchange Improvement Project in exchange for payment from Koll for the cost of the landscape improvements. Pursuant to the agreement, Koll paid the City $52,814 towards the construction of Koll's landscape improvement obligation. The amount of $41,956.89 for Change Order No. 10 will be paid from the payment received from Koll. Change Order No. 18 is needed due to the required revisions to the drainage systems along the eastbound and westbound auxiliary lanes of 1-580 between Tassajara Road and Fallon Road, and to the regrading of existing slopes to fit actual field conditions and facilitate drainage. This Change Order also includes the removal and disposal of several existing pipes, inlets, and a metal beam guardrail in conflict with the revised drainage systems. Furthermore, the Change Order will modify the existing drainage system by installing approximately 86 feet of corrugated steel pipe, constructing two drain inlets, and constructing rock slope protection. The total cost of this Change Order is $75,846.92. Change Order No. 33 includes the installation of 417 feet of 30-inch diameter pipe culvert, 10 feet of 18-inch diameter pipe culvert, construction of 4 drain inlets along the westbound diagonal on-ramp, and excavation and grading of an embankment, all of which is necessary to replace an existing v-ditch along the north side of the on-ramp. The new pipe system will provide more room for the freeway landscaping required along the westbound on-ramp. This Change Order will also remove and replace any damaged fences, irrigation facilities, and plants located within the Koll property. The total cost of Change Order No. 33 is $84,150.29. Caltrans has approved the design features of Change Order Nos. i0, 18 and 33. Staff recommends that the City Council approve Change Order Nos. 10, 18 and 33 in the total amount of $201,954.10.
