<br />AGREEMENT 1-2354 <br />'Exhibit A <br /> <br />.-- <br />-- <br /> <br />. <br /> <br />The CONSULTANT will prepare the preliminary engineering for up to two (2) new bridges <br />the project will require. This effort will be performed within months 6-18. <br /> <br />... <br /> <br />Task 5.14 Stmctural Specifications <br />Standard Technical Specifications for PE 5. scope of work. <br /> <br />PE 6. <br /> <br />Preliminary Trackwork Design <br /> <br />CONSULTANT will identify all trackwork elements and determine their quantities, <br />configuration and method of installation for in-street embedded track, off-street track, yard and <br />storage track, and tracks on aerial structure. <br /> <br />Using the Plan and Profile Drawings and the yard track layout, the CONSULTANT v;'¡'¡¡ <br />determine geographic limits and quantities of various track types and special trackwork. Using <br />relevant geotechnical information, noise and vibration mitigation requirements from <br />environmental studies, operating plans, and data about the CenterLine rail vehicles, the <br />CONSULTANT shall determine any special design requirements, maintenance restrictions, and <br />loading requirements for the CenterLine trackwork. The CONSULTANT should keep in mind <br />that it will be of value to The AUTHORITY to be able to jointly order, share, and swap track, <br />special track, ties, ballast, and fasteners with the Metrolink, Los Angeles MT A, or San Diego <br />Trolley operations. The CONSULTANT will therefore attempt to make use of the track designs <br />and standards utilized by nearby passenger rail systems, or report on why it is not in The <br />AUTHORITY's best interest to use them, CONSULTANT will clearly delineate trade-offs <br />among various track types, addressing noise, maintenance, initial cost, etc. <br /> <br />The CONSULTANT will prepare design standards for all included track configurations. In <br />doing this, the CONSULTANT will evaluate different tie designs from the point of view of life- <br />cycle cost, maintainability, compatibility with nearby passenger rail systems, and long-term <br />availability. Based on the results, the CONSULTANT will recommend design standard(s). ning <br />the CONSULTANT will evaluate the use of special trackwork of American and European <br />designs in the same way and recommend design standard(s) to be followed. The <br />CONSULTANT will analyze different approaches to embedded track design including proper <br />rail bonding to assure adequate track circuit signal transmission, stray current protection, noise <br />attenuation, etc" and recommend design standard(s) to be used, The CONSULT ANT will <br />prepare preliminary specifications and design drawings for each element of the track system. <br /> <br />The CONSULTANT will prepare a schedule for each type of track, croSS-over, turnout, at-grade <br />crossing, and other special trackwork indicating locations, quantities, spares/spare parts, and <br />basic installation method, Quantities of ties by type and ballast will also be calculated. This <br />infornlation will be used to develop cost estimates for each track component and for the <br />trackwork in total. The CONSULTANT will also prepare an evaluation of contracting strategies <br />for the procurement and installation of trackwork elements, <br /> <br />26 <br /> <br />6'''^ <br /> <br />--- ._~:" ~_.- -..;-- -.-- <br /> <br />'~ <br />
