<br />AGREEMENT 1-2354 <br />Exhibit A <br /> <br />key elements of the design, Assumes decisions required in Tasks listed above are made by the <br />end of the 4th month. <br /> <br />Task 10.06 Establish and Operate Power Simulation Model <br />Scope will include development of a train movement and traction power simulation model in <br />order to determine traction power substation locations. Initial output at the 6th month will be <br />tentative substation locations based on operating requirements (headways, number .(¡fcars per <br />train, etc) and power demands of the vehicle. Requirements for this phase will be: <br />. Completed Operations Plan, Schedule of Values Task 1.10, including treatment of <br />extensions/options <br />. General track alignment (plan and profile) and station locations <br />. Performance requirements per Schedule of Values Task 10.01. <br />. power supply and distribution technical characteristics, Schedule of Values Tasks 10,2 <br />and 10.04. <br />. Above items completed at end of 4th month. <br /> <br />, , <br /> <br />Task 10.07 Traction Power and Distribution Design Preliminary Engineering <br /> <br />Scope is as defined in PE 10. (30% design), Begins when Schedule of Values Task 10.05 is complete <br />and approved, Assumes the other following conditions: <br />. Alignment is generally fixed by end of 4th month and fixed in detail at end of 12th month. <br />. Alignment types (at-grade, aerial, and general/systemwide) are finalized by end of 4th month <br />and extents of each are finalized by end of 12th month. <br />. Power simulation study (Schedule of V.alues Task 10.06), including operational criteria, <br />completed and accepted by end of 6th month. <br />. Layout drawings will follow alignment Plan and Proflle scales. <br /> <br />Task 10.08 Baseline Stray Current Survey and Report <br /> <br />Scope includes measurement/testing of existing stray current conditions and discussions with <br />utilities on anticipated conditions/control requirements. Forms a basis for the design remediation <br />requirements and agreements with utilities, <br /> <br />Task 10,09 Corrosion Protection Report <br />. The report follows the completion of Schedule of Values Tasks 10.05 and 10.07. <br /> <br />PE 11. <br /> <br />Preliminary Engineering of the Communications Systems <br /> <br />CONSULT ANT will develop 30% designs for all communications systems including the public <br />address, train location, radio, telephone, SCADA, CCTV, fire/emergency, and ticket vending <br />machine network. It also includes communications design input for the Operations Control <br />Center designers, <br /> <br />44 <br /> <br />...".' <br />---;.... <br /> <br /> <br />G\.n <br />
