CITY OF EDMONTON - LRT DESIGN GUIDELINES

1.0 GENERAL

1.1 INTRODUCTION1.1.1 PurposeThe LRT Design Guideline Manual is prepared to provide information and direction to theConsultant, and outline standards governing the designs of various elements on EdmontonsLRT System. In addition, Drawings Standards, CADD standards, Design Briefing Reportsand a Quality Assurance / Quality Control Manual have been prepared, and must be adheredto by the Consultant during the engineering and construction phases of LRT projects.In addition to the forgoing, other specific guideline and standards documents have beenprepared to guide the design activities and the preparation of contract documents and arereferenced throughout this manual.The last revision to the LRT Design Guidelines was in January 1992. By bringing the LRTsystem to grade and its alignment entering residential areas, revisions and upgrades to theLRT Design Guidelines are required to reflect the future operating characteristics of the system.Designs should be conceived within an atmosphere of fiscal responsibility. Designs should beguided in maintaining low operating costs, minimizing capital costs (i.e.: design, construction,mitigation, aesthetics), and minimizing public and community disruption. Theserequirements must be balanced with the need to ensure public safety and access,environmental impacts, system reliability, and maintenance requirements.1.1.2 ScopeThis chapter provides general background on past LRT development in Edmonton, outliningthe collaborative approach to be taken on LRT plan development. It also presents the generaldesign philosophy and principles that guide the planning, design, and construction of the LRTSystem. In addition, it provides an overview of the commissioning process associated withmaking a newly constructed segment operational, and details of project closeout documentrequirements (plan of record drawings and operating and maintenance manuals).There are sixteen (16) specific design component chapters as follows: Vehicles and Clearances Clearances and Right-of-Way Alignment Trackwork Traction Power Signal System Communications Structures Stations and Ancillary Facilities Electrical Systems Mechanical Systems Corrosion and Stray Current Control Impact Mitigation, Aesthetics and ROW Control Accessibility Safety and Security Utilities Streets Design

CITY OF EDMONTON LRT DESIGN GUIDELINESGENERAL

Where appropriate, each chapter is supported by figures, diagrams, and tables at the end ofeach chapter. In some instances, applicable reference documentation will form an appendixto the chapter. Each chapter is to be as comprehensive and complete as possible.Notwithstanding the forgoing, due to the complexity of the topics, specific referencing to otherchapters or other related reference documents still occurs throughout a chapter.It is the intent of the City to also develop design guidelines for LRT Shop and Yard facilities forinclusion in this document at a later date.

1.1.3 Procedures and ApplicationThe material contained in the following chapters provides a uniform basis to direct the Consultants design. The intent, however, is not to restrict Consultant from exploring newideas, concepts and the application of new technologies. Also, through the design process,some refinement is to be expected. The guidelines do not substitute for sound engineeringjudgment and practice.The Consultant is responsible for identifying any proposed departures from the guidelinesstated within this manual. The Consultant must explain, and justify, any deviation from theseguidelines and secure all the necessary approvals. Any proposed changes must first be reviewed by the Project Manager and have the written approval of the City of Edmonton priorto use in design.

1.1.3.1 Codes and StandardsIt is the intent of the City of Edmonton, Edmonton Transportation and Streets, EdmontonTransit System, and Edmonton Asset Management and Public Works that all work be performed in compliance with all current local, provincial, and/or federal codes and standards.Where expressed differences between the various codes and standards occur, compliancewith the highest standard must be adhered to, unless otherwise directed by the local*authority having jurisdiction.*Note: Authority having Jurisdiction. A safety codes officer in the building discipline exercisingauthority pursuant to designation of powers and powers and terms of employment in accordance withSection 28 of the Safety Codes Act. The individual certified as a safety codes officer is given designatedpowers by the Safety Codes Council.

All codes and standards are listed in each chapter, if they are applicable.

1.1.3.2 Facility Development ReviewIt is a legal requirement that all facility designs be approved by the City of Edmonton,Planning and Development Department.The formal approval procedure by the Planning and Development involves two stages: Development Permit application and approval, which is usually coordinated through the

Citys representative. Approval of the detailed design and the issuance of a building permit. The contract

documents generally stipulate that the Contractor is for applying for and obtaining the building permit.

It is recommended that an informal process also be followed. This should take the form of on-going consultation with the Planning and Development Safety Code Section, PlanExaminers during the detailed design phase to deal with issues as they arise during thedesign development. The objective of the informal process is to ensure that the issuance ofthe building permit is more or less a formality and should minimize the requirement forchanges during and after the facility contract award. An appropriate number of drawings andspecifications will be provided by the PMO.



1.1.4 Abbreviations, AcronymsThe following abbreviations and acronyms appear throughout these Guidelines. Otherabbreviations or acronyms that are used will be stated in their respective chapters.

In January 2000, the name of the organization waschanged to Amercian Public Transportation, still retaining the same acronym APTA.

1.1.5 Project ManagementThere are numerous project management and project delivery strategies that could be employed, depending upon the size, timelines, desired contractual relationships, and staffingrequirements. It is the Citys objective to provide project coordination and execution in a timely and cost effective manner.Currently, the establishment of a Project Management Office has been the preferred means ofmanaging a major expansion to the LRT. The PMO consists of an independent managingconsultant who works in conjunction with various City officials and stakeholder involvementpersonnel.The Managing Consultant, although not directly responsible for the planning exercise,provides technical assistance and coordination services to the planning and stakeholderinvolvement teams. The MC is directly responsible for coordination of professional groupsinvolved in the planning, design, and construction phases of the project. As well, the MC isresponsible for all consulting (UPC & SSC) contracts. All contracts reside with the MC andnot the City.The MC is accountable to the City through the City LRT Project Office, acting on behalf ETS,as the operator of the LRT system.



1.1.6 HistoryEdmontons current LRT system totals 12.3 km of double track and provides access betweenClareview (139 Avenue and 43 Street) and the University of Alberta (87 Avenue and 114Street) within 20 minutes. The surface alignment is 7.6 km and predominately runs in the CNROW from Clareview toward the Citys downtown core. The underground alignment,including the DBM Bridge, is 4.7 km long and travels under the downtown area, across the river on the DBM Bridge to the University of Alberta. The current system operates with a fleetof 37 LRVs and has an average weekday rider-ship of 42,000 patrons.At the time of the issuance of these updated guidelines construction was underway on theextension from University Station to Health Sciences. Approximately 390 m of tunneling/cutand cover, 120 m of portal, and 200 m of station and approaches are required to bring theLRT to the surface. The portal is located adjacent to the Northern Alberta Jubilee Auditorium,approximately 105 m south of 87 Avenue. The at-grade Health Sciences Station is locatedjust north of 83 Avenue.In accordance with City Transportation Bylaw 11778, and the amending Bylaw 13423(approved October 2003), the approved alignment for the next extension is at grade, southalong the west side of 114/113 Street allowing the alignment to run under Belgravia Road andacross the northern portion of the Alberta Infrastructure property. The proposed station wouldbe located east of Foote Field together with a 12 bay *Transit Terminal for both westboundand southbound buses. Once south of the LRT station at Foote Field, the alignment swingseast on the south side of the School for the Deaf to 111 Street, via an underground portalstructure to facilitate the alignment being located in the median of 111 Street. The alignmentwill reach grade north of 57 Ave and continues to travel south down the median of 111 Streetto 23 Ave. Fully integrated stations, Transit Terminals and park and ride facilities are plannedat both the *Southgate Mall site and the old Heritage Mall Site. The entire proposedextension adds an additional 8.1 km of double track to the existing system.*Note: Once the Southgate LRT station is constructed, the Transit Centre at Foote Field will be for westbound buses only.

The City Transportation Master Plan states that, Grade separations with roadways at keyintersections may need to be considered in order to isolate LRT from vehicular congestionand to maintain the travel time reliability and superiority it (LRT) is intended to deliver. It alsostates that construction of the South LRT Extension from University to Heritage, includingtransit priority measures/improved bus access, enabling better access and future expansionto West Edmonton and Millwoods/The Meadows from the LRT Extension.

1.2 GENERAL DESIGN PHILOSOPHY

1.2.1 Principles of Light Rail Development and Busway Development

1.2.1.1 Statement of Intent The intent of this document is to articulate a set of basic principles, which will guide theplanning, design, construction and operation of Light Rail Transit (LRT) lines, Busways andrelated facilities in Edmonton.The purpose of including these principles as an appendix to the Transportation System Bylawis to ensure that the development of LRT and Busways in Edmonton is undertaken within a framework which is consistent with certain themes and objectives which transcend changes in decision making personnel and process.The inclusion of these principles in this Bylaw affords the public an opportunity to interveneand influence, through a statutory hearing process, in any proposed revision to or deviationsfrom the principles set out herein.



The principles are intended to be flexible enough so as to reflect and be subject to varyingsets of conditions, constraints and standards over time.It is anticipated that affected communities may ask City Council to consider site specificissues arising from the development of LRT or busways in their community.The order in which the principles are presented does not reflect any particular ranking, priorityor weighting. It is recognized and accepted that the relative importance of these principles willvary depending on situations and conditions. It is further recognized and accepted that insome instances specific applications of the principles may compete with each other, in whichcase decisions may require certain trade offs to be made.

1.2.1.2 Statement of PrinciplesPrinciple of Public ConsultationThe City is committed to ongoing consultation with parties who have an interest in issuesrelating to the planning and development of LRT and busways. It is recognized that thespecific consultation processes, which are undertaken, must be sufficiently flexible to allow forthe diversity of public views, which may be expressed over time and over different segmentsof LRT or Busway systems. The fundamental justification for public consultation is the premise that the public has a right to participate in decisions that may affect them.Principle of Personal SafetyThe City is committed to the development of a Light Rail Transit and Busway System whichin its design, construction and operation, meets with generally accepted principles of safetyand is consistent with sound and accepted engineering standards and practices. Thearticulation of these principles, standards and practices must take into account the safetyconcerns and physical, demographic and land use environments of the communities alongany given section of LRT line or Busway.Principle of Community ViabilityIn the design, construction and operation of the LRT or Busway system, the City ofEdmonton will use its reasonable efforts to maintain or reinforce those elements whichcontribute to the current viability of the communities adjoining the LRT or Busway systemwithin the bounds of practicality and feasibility. It is recognized and accepted that theelements, which influence community viability, may vary from community to community.Principle of Impact MitigationThe City is committed to the practical and feasible mitigation or reduction of negative impactson adjoining communities, which may arise from the development of the LRT or Buswaysystem.Principle of Fiscal ResponsibilitiesThe City is committed to the development of the LRT or Busway system in a manner, whichis consistent with its fiscal capabilities, and fiscal priorities as may be established from time to time by City Council, as agent for the citizens of Edmonton.Principle of Community Stability and Appropriate RevitalizationIn its decisions relating to land development, land use change and possible relateddemographic implications, the City will ensure adherence and consistency with the spirit,objectives and policies of the Municipal Development Plan and other planning instruments asmay be adopted and amended from time to time.Principle of Growth Accommodation through Public Transit EnhancementThe City affirms its commitment to the provision of an effective public transit system as a means of accommodating the Citys growing travel demands.



1.2.2 Stakeholder InvolvementImplementation of LRT into residential areas introduces new environmental and socialimpacts into the surrounding neighborhoods. For this reason, stakeholder involvement hasbeen recognized as a major and critical component of the LRT expansion. The stakeholderinvolvement effort will be led by a consultant team in conjunction with the TransportationPlanning Branch of T&S and supported technically by the Managing Consultant and ETS (C-LRT and Light Rail Transit division).The overall goal of stakeholder involvement is to ensure an exchange of information betweenaffected residential, institutional and corporate communities, and the project team.Stakeholder involvement will ser
