<br />AGREEMENT 1-2354 <br />Exhibit A <br /> <br />~-' <br />..-- <br /> <br />. <br /> <br />Design and specification of the CCTV System to the 30% design level. <br /> <br />. <br /> <br />Design and specification of the Public Address/ Changeable Message Sign System to the <br />30% design level. <br /> <br />The CONSULTANT will establish a QC system with civil designers and statiorl architects to <br />ensure that the equipment specifications, conduit sizes, conduit and equipment/component <br />locations, and floor layouts for the Operations Control Center, communications buildings, and <br />platform areas meet system requirements and have been incorporated into the designs. The <br />CONSULT ANT shall also address the means to secure the control and communication systems <br />in the event of an emergency or secUl~ty threat to the CenterLine system, its passengers, or an <br />individual¡,assenger. <br /> <br />The following paragraphs describes in greater detail the work scope that resulted from the <br />CONSULTANT's input during negotiations of the PE consulting services contract. <br /> <br />The following clarifications are included as part of the CONSULT ANT's Schedule of Values: <br /> <br />Task 11.01 Design Criteria <br /> <br />The following assumptions apply to this task: <br />. Design Criteria for PE 11. scope of work. <br />. Completed Operations Plan Schedule of Values Task 1.10, including treatment of <br />extensions/options and location of OCC, are completed by end of the 4th month. <br /> <br />Task 11.02 Conduct Radio Systems Study and Report <br />. As defined in PE 11. <br /> <br />Task 11.03 Communications System Design Preliminary Enginee¡~ng <br /> <br />The following assumption applies to this task: <br />. Number, type, and configuration of passenger stations known generally by end of 4th month <br />and specifically by end of 12th month. <br /> <br />PE 12. <br /> <br />Train Control and Signal System <br /> <br />CONSULT ANT will review the Rail System Specifications Report prepared during Conceptual <br />Engineering to understand the approach to be taken in advancing the train control and signal <br />system. Where the CenterLine trains will be operated by the dr:iver in streets there will be an <br />Automatic Train Protection system and an Automatic Train Stop subsystem at interlockings and <br />switches. Road crossings have Automatic Highway Crossing Warning devices, While street <br />running, trains will be controlled by trafflc lights. Overall General Order 143-A, Safety Rules <br />and Regulations Governing Light Rail Transit of the California Public Utilities Commission will <br />control the design, <br /> <br />47 <br /> <br />Q" <br /> <br />
