<br />. <br /> <br />The conceptual engineering will include: <br /> <br />· Analysis of potential private aHd public utilities. Preliminary designs te rectify any major <br />conflicts between the commuter rail facilities and the. affected utilities will be completed. <br />This analysis will include preliminary drainage analysis and design: The design wilhize'"aii"d <br />locate any required detention and/or retention facilities for storm water. <br />· Preliminary grading plan tn order to determine right-of-way <br />· - General assessment of any unusual soil conditions <br />· Property acquis~tion Tequirements <br /> <br />There products will be combined with the outputs from Task 2.1 and submitted to each <br />governmental agency with review and/or approval responsibilities. <br /> <br />5.5 Other Infrastructure Revisions <br /> <br />The Contractor will develop conceptual designs of revisions to various existing infrastructure <br />features which are required or desired to permit or facilitate commuter rail construction and <br />operation. Beyond resolving conflicts with various utility lines and structures (addressed in Task <br />5.4), there will be need to make adjustments to other existing infrastructure features to permit the <br />commuter rail facilities to occupy space and exist permanently. Under this task, major changes to <br />streets, highways, bridges, sidewalks, traffic control devices and the like will be identified and <br />conceptually defined. <br /> <br />. <br /> <br />5.6 <br /> <br />Conceptual Systems Engineering <br /> <br />As the first step in the process, the Contractor will develop a set of functional design and <br />operating criteria for the system components of the commuter rail system. The systemwide <br />components include commuter rail vehicles, signaling systems, communications systems, central <br />control, and the fare collection system. The criteria will establish the physical limitation of the <br />components, such as dynamic envelope and minimum curve radius for the vehicles, and the <br />general performance expectations. The analysis will be based on the generalized requirements <br />from applicable existing commuter rail systems. <br /> <br />The Contractor will then prepare a conceptual outline specification for each of the following <br />system-wide components: <br /> <br />· Vehicles <br />· Fare collection <br /> <br />The Contractor will prepare a conceptual outline specification in coordination with BNSF for <br />each of the following system-wide components: <br /> <br />· Central control <br />· Signal system <br />· Communication system <br />· Security <br /> <br />. <br /> <br />A key element of this task will be the relationship to BNSF signal and control system. <br /> <br />Work Program for Northstar Corridor MIS and EIS <br />For the Proposed Commuter Rail Service <br />February 25, 1999 <br /> <br />~. <br />~7l <br /> <br />21 <br />Work Program <br />
