(.I N -2 This contract does not include the landscaping of the facility. Caltrans insists that landscaping be bid and awarded separately, per their procedures. This is due mainly to the fact that Caltrans requires the contractor to maintain the landscaping for three (3) years after installation, and it is unreasonable to hold the bonds for the entire project for that period of time, merely for landscaping. Construction is estimated to take 18 months. Prior to the start of construction, major utilities have to be relocated. The utility relocation is being scheduled and is not expected to conclude until the end of the year. For this reason, construction on the interchange is not expected to begin until the weather dries out in March of 2004. However, the Contractor may suggest an alternate plan that may advance the completion date. The project is designed by the civil engineering firm of Mark Thomas and Company. They also designed the Route 101 Auxiliary Lane project, which is currently under construction. The main agreement with Mark Thomas was entered into with Belmont in 1999 and is assigned to Redwood City as part of the cooperative agreement between Redwood City and Belmont. After clearing many hurdles required by Caltrans, the project advertised on July 1, 2003. The project was not only advertised in the local newspaper, but also appeared in the regional construction newspaper on July 2 nd and 9"' and was also advertised online. A pre -bid conference was held on July 15, 2003. The bid opening was held on August 6, 2003, in the office of the City Engineer. A total of five (5) bids were received, which are summarized below.

Jones & Sons, Inc. with a Alternative 2 (Slab Bridge) bid of $12,426,983.00 appears to be a good and responsive bid.
