SUNOL BOULEVARD/I-680 IMPROVEMENTS <br /> PAc4&FD <br /> Subtask 5.10-Highway Plan Sheets. <br /> CONSULTANT will develop layout plans for up to two Build Alternative(s)that indicate <br /> lane, shoulder,horizontal control, structure locations and right of way requirements in <br /> MicroStation format using the topographic base mapping prepared in Task 2. Typical <br /> cross sections and roadway profiles and superelevation diagrams of new and modified <br /> alignments will also be developed. <br /> Subtask 5.11 -Design Exceptions. <br /> CONSULTANT will check the geometries of the existing and proposed state facility for <br /> non-standard features and update the list of Boldface and Underline design exceptions <br /> identified previously(Task 2), if necessary. Geometric refinements will be further <br /> investigated to assess if any non-standard features can be eliminated. Design Standard <br /> Decision Document will be drafted and submitted to Caltrans HQ geometrician and <br /> District 4 for review and comment. CONSULTANT will address any comments and <br /> submit final Design Standard Decision Document for Caltrans approval,prior to <br /> submittal of the Draft Project Report. Boldface design exceptions for vertical clearance, <br /> stopping sight distance, and corner sight distance are anticipated. Traffic and accident <br /> analysis,physical constraints, cost, access control, and environmental impacts will be <br /> critical factors in justifying the design. <br /> Subtask 5.12-Landscape&Aesthetics Concept. <br /> CONSULTANT will prepare a technical memorandum that provides agreed upon <br /> guidance for the future development of the landscape and aesthetics elements of the <br /> project. <br /> Subtask 5.13 Life Cycle Cost Analysis. <br /> CONSULTANT will prepare a pavement Life Cycle Cost Analysis (LCCA) for proposed <br /> ramp work,with the results summarized in a report. LCCA will be performed per <br /> procedures and guidelines from the latest Caltrans Pavement Policy Bulletin, and using <br /> Real cost software. A pavement strategy checklist will be developed. <br /> Subtask 5.14 Final Engineering Technical Reports <br /> Technical reports will be updated based on comments received from reviewing agencies. <br /> A matrix of review comments and their responses for each report will also be compiled. <br /> April 10,2020 2 2 <br />
