Standard and directive drawings will be prepared during preliminary engineering and final design to standardize and guide the design activities and preparation of procurement and construction documents. Design is to be directed toward optimizing the design including considerations such as costs for design, construction, capital facilities; operating expense; energy consumption; and minimizing disruption of local facilities and communities; and meeting aesthetics, community, and local agency standards. It should be consistent with passenger safety, system reliability, service comfort, mode of operation, type of LRT vehicle to be used and maintenance considerations. 1.2 SCOPE These Design Criteria, which refer to the most recent addition of the State of Minnesota Building Codes, will take precedence over all other standards referred to herein except those fixed by legislation. Specific attention should be given to Final Rule of the U.S. Department of Transportation regarding Transportation for Individuals with Disabilities, published in the Federal Register of September 6, 1991, and to any subsequent modifications that may be issued. The applicability of that document is noted in several sections of this design criteria manual where it appears to be particularly appropriate. However, the regulations must be adhered to in all areas, whether or not mentioned here. The performance and design criteria in this part relate to the following LRT facility and system elements: • Fire/Life Safety; • Track Geometry and Trackwork; • Utilities; • Landscaping and Urban Design; • Stations; • Tunnel Alignment Structures; • Light Rail Vehicles; • Operations and Maintenance Facilities; • Traction Electrification System; • Signal System; • Communications and Central Control; • Fare Collection; • Civil Engineering; • Traffic Engineering; and • Structural Engineering. Revision 0 1.3 PROCEDURES Drawings and technical specifications shall be prepared for the project in accordance with these design criteria and CCPO LRT Design Standards as established during the design and construction of the Central Corridor LRT project. All drawings and technical specifications shall be prepared in accordance with the Project’s Quality Assurance Plan (QAP) Deviations may be made within the framework of these Design Criteria to meet the requirements of a particular problem. However, any deviation, discrepancy, or unusual solution must be approved by the Central Corridor Project Office (CCPO) before it can be included in the design. It is the responsibility of the Designer to identify, explain, and justify any deviation from the established criteria and to secure the necessary approvals from the CCPO. As this Part is revised, modified, or augmented, the Revision Records for each section will show the page number, date, and appropriate section decimal notation for each change or addition. Individual pages will also indicate the revision date and page number. Proposals for revisions shall be directed to the CCPO for approval. 1.4 DESIGN CODES AND MANUALS In addition to these criteria, the Designer must comply with all other applicable engineering codes and standards, including those of the various federal, state, and local jurisdictions. If codes and/or manuals are specified herein for the design of an element of Central Corridor LRT system, then the edition(s) in effect at the time of contract award shall be used. Specific codes and standards include, but are not limited to, the following: • Americans with Disabilities Act (ADA); • US Department of Transportation Final Rule - Transportation for Individuals with Disabilities; • Minnesota Department of Transportation Standard Reference Manuals; • City of Saint Paul Standards • Ramsey County Standards • Hennepin County Standards • City of Minneapolis Standards; • Capitol Area Architectural and Planning Board (CAAPB) Comprehensive Plan and Design Criteria • Manual on Uniform Traffic Control Devices for Streets and Highways; • Minnesota Manual on Uniform Traffic Control Devices; • State of Minnesota Uniform Building Code; • State of Minnesota Sustainable Building Guidelines (MSBG); • Standard Specifications for Highway Bridges, American Association of State Highway and Transportation Officials (AASHTO); • Manual for Railway Engineering, American Railway Engineering and Maintenance of Way Association (AREMA); • Steel Construction Manual, American Institute of Steel Construction (AISC); Revision 0 • Structural Welding Code and Bridge Welding Code, American Welding Society (AWS); • Building Code and Commentary, American Concrete Institute (ACI); • American Society for Testing and Materials, American Society for the Testing of Materials (ASTM); • National Bureau of Standards; • National Electrical Code (NEC); • American National Standards Institute (ANSI); • Standard Specifications for Structural Support for Highway Signs, Luminaries, and Traffic Signals, American Association of State Highway and Transportation Officials
