Staff recommends approval of Construction Change Order No. 8, consisting of the following items: 1. Additional compensation in the amount of $19,391.00 for differing site conditions encountered during drilling for bridge piles. The contractor encountered cobbles up to 12" in diameter that required significant re -drilling and repair of excavations with slurry. Staff Report — Contract Change Order 8 to C22870B Granite Page 2of2 November 8, 2007 2. A credit in the amount of $44,460.00 for changing the rebar size and spacing in the channel slope paving requested by CVWD. 3. Additional compensation in the amount of $89,936.00 for the costs incurred by the contractor related to the 77-calendar day delay due to the relocation of Verizon conduits, manholes, and cables. It is the intent of staff to seek reimbursement from Verizon for this delay cost. 4. Deletion of landscaping and irrigation work from contract plans at a credit of $95,000.00. The landscaping plans and specifications were revised to meet current standards and requirements and address requests of adjacent property owners. Staff and the contractor were unable to agree on a price for the revisions; therefore, the work will be bid as a separate project. 5. Granting of a 192-calendar day extension due to the Verizon delay and for Change Orders 6 and 7 that was to be determined later. The new project completion date is November 16, 2007. Including this change order, the total amount of change orders to date is $1,034,489.00 or 10.3% of the original contract amount. Submitted By: Departmen H John A. Garcia, P.E.
