the PG&E 230 kV underground electrical transmission line proposed to be routed through Pleasanton. By combining resources from a variety of sources, such as the School District's paying for its share of all Specific Plan infrastructure ahead of time, it was possible to fund the required infrastructure improvements. As provided in the Financing Plan, to the extent any funding source pays more than its fair share, there will be reimbursement from Specific Plan fees. To facilitate construction of the initial phases of roadway improvements, it was agreed that Greenbfiar Homes Inc. would contract for the required infrastructure improvements (it contracted with DeSilva Gates Construction) and that Greenbriar would provide construction management for the project at a fee of 5% of construction cost. The City and the developers estimated the cost of the infrastructure improvements for these initial phases of roadway improvements to be approximately $6.6M (including completion of design, mass grading, infrastructure construction, and construction support services, including a management fee). The base construction cost for roadway improvements (including the initial phase of the school loop road) was $5,204,318.70. In addition, the net cost of completing roadway grading (after PG&E's reimbursement for a portion of this work) was approximately $400,000. Consulting fees for completing design tasks were estimated at $200,000, fees for construction support were estimated at $250,000, and management fees were estimated at approximately $270,000. These cost estimates left a small amount for project contingency (approximately $280,000) out of the original $6.6M funding. Roadway Construction Construction began with the mass grading of the proposed roadway alignment in August of 2002 to accommodate the construction of a 230kV underground transmission linc by PG&E along the new alignment. The grading work was completed in late 2002 at a cost of $862,600. At the request of PG&E, mass grading was completed as an early phase of construction, which necessitated thc installation of temporary storm drainage facilities and a rescqucncing of the roadway construction activities. The roadway contractor vacated the project site as the PG&E contractor installed thc underground duct bank for thc 230kV transmission linc. PO&E paid for the extra work required to accommodate its needs in thc amount of $488,965, resulting in a net cost for grading for the roadway of $373,635. Subsequent to the completion of the underground transmission linc by PO&E, Orecnbriar Homes Inc. awarded a construction contract to DeSilva Gates in June, 2003 to complete basic roadway improvements for the realignment of Vineyard Avenue. The original contract amount was for $$,204,318.70, which included roadway infrastructure for the realigned Vineyard Avenue, roadway widening required at the Katz Winery driveway (to be reimbursed by Michael Callahan), basic improvements for the loop road around the future Neal School site, and SR:05:120 Page 3 of 7
