The bridge is being constructed in two stages with one lane in each direction open to traffic throughout construction. The 447-foot-long bridge between Magnesia Falls and Quicksilver Drive will be approximately 40 feet above the channel at is highest point. The Notice to Proceed to Granite Construction was issue on August 22, 2005. Construction of the bridge is now approximately 40% complete. On July 31, 2006, the east phase was completed and traffic was moved to that portion of the bridge. Construction of the entire bridge is scheduled to be complete in May 2007. JJ 33..§§ .... P.

Amendment 2 to C22870 with Moffatt & Nichol-Portola Bridge over Whitewater Page 2 of 2 August 24, 2006 Discussion: Moffatt & Nichol has expended approximately $20,000.00 in additional services analyzing the girder failure that occurred and reviewing the pile layout due to contractor's surveying error. This amount will be deducted from payment due the contractor. Staff has prepared Amendment 2 to Contract No. C22870 after negotiating with Moffatt & Nichol Engineers for additional construction design support services required to complete bridge construction. The additional services include the following tasks: • Analyzing girder failure/girder sweep corrections submitted by contractor • Preparing revised plans for change orders • Adjusting pile layout requested by contractor • Performing preconstruction survey for milk vetch plants • Responding to an unusual number of requests for information from contractor Staff has determined that the negotiated cost for the additional services is equitable and recommends that City Council, by minute motion, approve Amendment 2 to Contract C22870 with Moffatt & Nichol Engineers. The revised total contract amount of $662,718.00 is approximately 6.6% of the construction cost, which is well within the accepted range of up to 10% for design and construction support services for a project of this size and type. Therefore, staff recommends that City Council C22870 with Moffatt & Nichol Engineers in construction design support services to comp Bridge over the Whitewater Channel, and contingency to base and appropriation of $4'4 400.
