<br />CITY OF PLEASANTON <br />VINEYARD TRAFFIC CIRCLES <br /> <br />EXHIBIT A: SCOPE OF WORK <br /> <br />Bellecci & Associates ("CONSULTANT") is being retained by City of Pleasanton <br />"CITY" to prepare plans to remove two traffic circles on Vineyard Avenue and <br />replace with conventional roadway intersection ("PROJECT"). CITY is planning <br />to remove traffic circles replace with conventional roadway intersection with stop <br />signs and left turn pockets. Removal of traffic circles will require engineered <br />transitions and tapers to match the existing roadway cross section east and west <br />of the two traffic circles to be removed. CONSULTANT is being retained to <br />prepare plans, specifications and estimates for public bidding in conformance <br />with City of Pleasanton standards. The scope of work is described in more detail <br />below: <br /> <br />1. BASE MAPPING - <br /> <br />CONSULTANT will assemble and review existing data from CITY, obtain new <br />field data, and prepare base plans for the proposed roadway improvements. <br />Perform topographic field surveys and develop base plans at a scale of 1" = 20'. <br /> <br />1.1. Field Work - Within the project limits CONSU L T ANT will survey roadway <br />cross sections, intersection lane configurations, traffic circles, identify <br />surface evidence of existing underground and overhead infrastructure, <br />and other existing improvements as determined by CONSULTANT as <br />needed to design the roadway. The Project Engineer will supervise the <br />field survey to ensure the field survey includes items needed for the <br />design team to tie-in all affected surface conforms. CONSUTLANT <br />shall Perform 2 days of field surveying. <br /> <br />1.2. Office Mapping - The record maps combined with the field survey <br />information will serve as the Project Topographic Base Map. Basis of <br />Bearing and Benchmark will be included on the Survey. CONSULTANT <br />will distribute project base mapping to all design team members and <br />make accessible readily upon each design stage. This topographic base <br />map will be the uniform "x-reference" for all design work. <br /> <br />2. PRELIMINARY ENGINEERING <br /> <br />2.1. Preliminary Plans <br /> <br />2.1.1. Preliminary Design - CONSULTANT will prepare at 20 scale, a <br />preliminary design which shows the proposed intersection <br />geometry for removal of the Traffic Circles. The plan will identify in <br />a the proposed intersection geometry, lane widths, curve radii, <br />traffic channelization, lane tapers, design exceptions and other <br />information as deemed appropriate by the design team.
