, October 16, 1995(revised 11/20) EXHIBIT "A" BKF No. P95446 2) Record Drawings/As-built Plans 3) Utility Maps 4) Right-of-Way Maps 2.1.2 Review material and determine the extent of the construction work. 2.1.3 Base sheets will be prepared using aerial photography to establish construction constraints and project magnitude. DELlVERABLES ,- 1) Summary of information collected. 2) Determination as to the limits of the auxiliary lane project and the capacity improvement project. 3) Base sheets and construction constraints. 2.2 CONCEPTUAL DESIGNS BKF will develop two separate interchange conceptual plans to depict the Auxiliary Lane Project and a plan incorporating the proposed Capacity Improvements to clearly illustrate the common components and project interface locations. Current highway standards such as HOV and ramp metering requirements will be implemented into the conceptual design. The "big ticket" items such as right-of-way and structure requirements will be determined to accurately evaluate construction costs. Design alternatives as a result of value engineering analysis will be presented. Based on the developed conceptual design, a preliminary cost estimate including applicable utility relocation and right-of-way costs will be prepared. The design approach for the capacity improvement interchange project will be the same in depth process as the auxiliary lane conceptual design. The design will be compatible with the proposed auxiliary lanes along the Bayshore Freeway and incorporate the recommendations established by the traffic analysis to increase the interchange capacities. City and roadway improvements will be addressed as dictated by the proposed conceptual design. An informal value engineering analysis will be conducted in conjunction with the Technical Committee and Caltrans to produce viable design alternatives which may be considered by the committees. A preliminary detailed construction cost estimate for the capacity improvements design will be developed. The following steps will be taken to complete these tasks for both the conceptual plan for the auxiliary lane (Task 2.2.1) and the conceptual plan for the capacity improvements (Task 2.2.2): 3 .
