2. Approve the Fourth Amendment to Agreement with BKF Engineers to finalize the PS&E for the landscape and gateway design, obtain a Caltrans encroachment permit rider for the landscape and gateway construction, and provide services during the advertising and bidding period to respond to questions from contractors and assist the City in preparing contract addenda as needed. Section 4 of the agreement is amended to increase compensation by $77,000 for a total compensation of$449,066. 3. Authorize the City Manager to execute the Fourth Amendment to Agreement. FINANCIAL STATEMENT Sufficient funds are available in the Bernal Interchange Reserve project (CIP No. 005068) to fund the additional cost of both the Third Amendment ($74,400) and the Fourth Amendment ($77,000). BACKGROUND The City of Pleasanton entered into a development agreement in October of 2000 with GHC Bernal Investors. Included within the development agreement were provisions for the payment and construction of the 1-680 at Bernal Avenue interchange improvements. Although the City is responsible for construction of the improvements, the cost of the construction will be the responsibility of the developers. In September 2010, the City Council approved a Professional Services Agreement with BKF Engineers to prepare the project plans, specifications and estimates and environmental documentation for the Bernal Avenue at 1-680 Improvements for a not to exceed amount of$297,666. DISCUSSION Caltrans has required that an archaeological test program be completed and a technical report be submitted to Caltrans for review and approval prior to the start of any construction activity. As a result, BKF Engineers and their sub consultant will perform an archaeological test program and prepare the technical report for Caltrans' review and approval. During the development of the final plans, the project work plan was expanded to include new curb ramps and pedestrian signals at the intersection of Bernal Avenue and W. Lagoon Road to improve the pedestrian facility. Also, additional drainage improvements are required under 1-680, and recent electrical work completed by Caltrans at the interchange will require modifications to the plans. BKF Engineers' services are required during the bidding process in order to respond to questions from contractors, attend meetings, and assist City staff in preparing contract addenda as needed. These additional services are included in the Third Amendment (Attachment 1) that was approved by the City Manager to keep the interchange project moving forward in order to avoid cost increases to the project. During the development of the PS&E, it was decided that the landscape and gateway elements of the project would be phased and constructed separately from the roadway improvement project. The landscaping was removed from the first phase of the contract in an attempt to expedite the Caltrans permitting process. Caltrans has issued an encroachment permit for the construction of roadway improvements. BKF Engineers Page 2 of 3
