ATTACHMENT 2 CITY OF DUBLIN "celebrating 25 Years Of Cityhood 1982-2007" 100 Civic Plaza, Dublin, California 94568 Website: http://www.ci.dublin.ca.us July 23, 2008 Mr. Rob Wilson Public Works Director City of Pleasanton 200 Old Bernal Avenue, Pleasanton, CA 94566 RE: Request for Approval of Design Funds - I-580/Fallon Road Interchange Project Dear Rob: This letter summarizes the City of Dublin's request for approval of design funds for the 1- 580/Fallon Road Interchange Improvement Project. In June 2003, the Cities of Pleasanton and Dublin entered into a reimbursement agreement for final design and construction of the I-580/Fallon Road Interchange Improvements. At that time, Pleasanton agreed to contribute $202,871 towards final design. Since then, Caltrans required additional interchange improvements which necessitated furtherdesign work. Dublin amended its contract with the designer to complete the plans and in March 2008, Dublin advertised the project. At that time Pleasanton was responsible for 18.2% of construction cost based on the final cost estimates. The bids were opened in April 2008 and the contract awarded in May 2008. Accounting of the percentage share based on the unit costs submitted by the contractor showed the percentage share due Pleasanton dropped to 15.58%. With regards to design costs associated with Pleasanton-related improvements, it was agreed to use the same percentage (15.58%) to determine Pleasanton's fair share of the additional design costs incurred by Dublin to complete the plans. The City of Pleasanton's share of addtional design cost is calculated at $120,291. We therefore request approval of these funds for project design. Also this letter memorializes Pleasanton's share of construction and construction management costs based on the 15.58°~ Pleasanton share of total construction cost. Based on this percentage share, Pleasanton is expected to contribute an estimated $252,001 towards construction management and $1,720,000 towards Construction.
