These additional activities represent engineering and geotechnical effort that was not included in the original contract scope of work and Amendments No. 1 and No. 2 for this project. In addition, at our PDT meeting with Caltrans on December 13, 2002, Caltrans had raised the issue of processing this project through federal requirements since this project will introduce two additional access points onto I -580. We are also requesting Engineering Services during Construction which was requested previously but has not received confirmation. Each additional management, engineering, geotechnical, environmental, traffic, and construction support service activity is described and a corresponding cost identified within the text of the "Additional Scope of Work No. 3" attachment. A cost breakdown by activity and team firm is presented on the accompanying spreadsheet. Part of these cost increases for the I- 580/Fallon Road Interchange Project are related to the additional northbound to westbound loop as requested by City of Pleasanton, and the design schedule delay associated with the additional loop. As you know, the additional traffic study, Geometrics Approval Drawings, environmental updates, and revision to the PSR/PR due to the addition of this NB/WB loop are covered in our Amendment No. 2 request, this amendment is for design effort to complete the contract plans. The fee proposal prepared in April 2000 anticipated that final design would be completed by early 2001. Due to the extension of the design phase, this request is to update the hourly rates to the current 2003 rates. The new rates to begin in January 2003. We are also requesting to include Engineering Services during Construction into this amendment. In March 2001, City of Dublin had requested CCS to prepare scope and budget for this activity since Construction Support Services is not included in the original scope of work. CCS prepared and submitted the information to City on March 23, 2001 but has not been submitted as an amendment. Since this project now includes City of Pleasanton funding portion of design and construction, the attached spreadsheets include segregated City of Dublin's share and City of Pleasanton's share.
