Sections and <br /> tables will be presented. <br /> 9.10.3 Ii%edestdan IRiridges <br /> The URS team will perform structural design with the 2 pedestrian bridges as discussed in Section 9.9.1. <br /> 9.1.1. Systenris Engineering <br /> Develop an LRT electrical and communications systems design to meet the operational <br /> performance goals. <br /> 9.11.1 Traction Powerr <br /> It is assumed that pre-packaged substations will be used. If there is an architectural treatment to be <br /> applied, it is assumed to be the same for all substations. The architectural design will be handled via <br /> graphics. In addition, the URS team will do the following: <br /> Perform traction power Load Flow Simulation models for the proposed traction power system. <br /> Determine locations and rating of substations and coordinate with site plans. <br /> Coordinate with the utility companies to locate and design the electrical service connections. <br /> Prepare substation typical equipment layout which will also serve to size the structure. <br /> IN Develop site plans showing the arrangement of the substations within its immediate area and in <br /> relation to the property being used. Utility service will also be included on the site plans. <br /> Single line diagrams will be prepared in accordance with the design criteria. <br /> Deliverable: <br /> N Traction Power Load Flow Simulation Model/Substation Location Report <br /> 9.11.2 OCS Plans <br /> It is assumed that dual wire, high and low profile OCS system will be designed except for Erwin Road. <br /> Erwin Road will be assumed to be wireless or be a single wire system. <br /> Decide on preliminary pole locations and produce OCS layout plans. <br /> Coordinate OCS design with traction power substation and appropriate sectioning. <br /> Coordinate the OCS and Power System design with consideration of future additional expansion <br /> at each terminus <br /> 9 11.3 Signalhng <br /> The signaling design will be coordinated with the grade crossing designs and traffic signal designs. Single <br /> line track/signal layout plans will be produced along with signal cable plans and signal route and aspect <br /> plans and schematics.This includes the following: <br /> NR': Coordinate with traffic signal designers to establish train-to-wayside communication systems for <br /> any necessary train signal integrated into the traffic control design. <br /> IDUrlhar -Orarige Il...igll-it IRaill Turainsit I1::)roject � June 203.3 19 9 IIDR Fr <br />
