This manual is intended to be a comprehensive guide that documents the typical design processes and criteria to be used for projects conducted by and for the City of Vancouver. In accordance with the City’s Organizational Quality Management (OQM) practices, each design assignment should be completed in accordance with a design brief which will stipulate the unique specifications for the assignment, which may differ from this manual as prepared and amended by the City of Vancouver. The scope of this manual is split into 10 chapters relating to various aspects of design in the City of Vancouver. Chapter 1: Introduction Chapter 6: Neighbourhood Energy Chapter 2: Design Process & Coordination Chapter 7: Third-Party Utilities Chapter 3: Water System Chapter 8: Streets & Transportation Chapter 4: Sanitary Sewer System Chapter 9: Streetscape & Urban Forest Chapter 5: Storm Drainage System Chapter 10: Street Lighting & Traffic Signals This Engineering Design Manual is to be used in coordination with the City of Vancouver Standard Detail Drawings. For construction specifications, see the City of Vancouver Construction Specifications and the City of Vancouver Supplemental General Conditions. | Page 5 | City of Vancouver Engineering Design Manual | 2019 1.2 PURPOSE The purpose of this manual is to consolidate the City of Vancouver’s design preferences and criteria into one comprehensive and cohesive document. It is intended to be used by a variety of people including City staff, City officials, and design professionals such as consulting engineers and architects working on behalf of the City, Third-Party Utilities, or developers. This manual provides general standard design criteria but cannot cover all specific situations. It is up to the designer to interpret these guidelines and apply them appropriately. The City is a design, build, operate, and maintain organization which does have in-house expertise that can assist with the interpretation and application of the standards / criteria in this manual. This design manual is meant to provide guidance and processes for how design is typically conducted in the City of Vancouver; noting that use of accepted industry standards and specifications will likely still be required. The City reserves the right to review, provide comment on, and accept or reject designs whether they conform to the guidance within this document or not. The City of Vancouver: (i) accepts no liability for any loss or damage which may be suffered by any person as a result of the use of this document; and (ii) makes no representation or warranty as to the appropriateness of the use of this document in any particular situation. This document is issued on the strict understanding that each user accepts full responsibility and liability for its use. It is the responsibility of designers to use sound professional judgment, knowledge and experience when using this document. City of Vancouver Engineering Design Manual | 2019 | Page 6 | Introduction INTROUCTION 1.3 DESIGN PHILOSOPHY The City of Vancouver aims to be one of the most sustainable and livable cities in the world today and in the future. The City’s design philosophy is paramount to progressing towards and achieving these objectives. This section outlines the context, strategies, and vision that all projects designed in Vancouver must acknowledge and incorporate. 1.3.1 DESIGNING WITHIN CONTEXT The City of Vancouver’s mission is to create a great city of communities that cares about its people, environment, and opportunities to live, work, and prosper. The City of Vancouver conducts itself based on these six values: • Responsiveness - We are responsive to the needs of our citizens and our colleagues. • Excellence - We strive for the best results. • Fairness - We approach our work with unbiased judgement and sensitivity. • Integrity - We are open and honest, and we honour our commitments. • Leadership - We aspire to set examples that others will choose to follow. • Learning - We are a learning workplace that grows through our experiences. Consistency, continuity, cohesiveness, and quality are important aspects of design in the City of Vancouver. Historical, cultural, and aesthetical qualities of the surrounding area should be preserved and enriched. Design should align with the goals and vision of the community and future development plans. Community plans and zoning by-laws influence each design; all projects should strive to enhance the livability of the space and promote a vibrant community that is inclusive to all people. Designers must integrate constructability, operations, and maintenance considerations during design development. Quality of infrastructure is highly important, and it is promoted and upheld by in-house expertise. 1.3.2 CITY STRATEGIES The City of Vancouver has many strategies and goals that influence engineering design. Below is a list of some of the relevant City strategies: 1) Engineering Strategic Plan – The Engineering Strategic Plan outlines 10 common goals of all engineering projects in the City: • Goal No. 1: The City provides excellent service. • Goal No. 2: The City is financially healthy and administratively effective. • Goal No. 3: The City leads the way on green issues. • Goal No. 4: The City inspires excellence in the workplace and in its employees. • Goal No. 5: The City optimizes strategic partnerships and collaborations. • Goal No. 6: Vancouver is a sustainable, affordable, livable and inclusive city. | Page 7 | City of Vancouver Engineering Design Manual | 2019 • Goal No. 7: Vancouver’s business climate is dynamic and robust. • Goal No. 8: Vancouver is a safe city in which people feel secure. • Goal No. 9: Vancouver offers extraordinary civic amenities. • Goal No. 10: Vancouver’s assets and infrastructure are well-managed and resilient. All engineering projects undertaken in the City of Vancouver should strive to meet and incorporate these goals, and projects should be guided by the ideals of the Engineering Strategic Plan. 2) Greenest City Action Plan - The Greenest City Action Plan is a strategy for staying on the leading edge of urban sustainability. The City of Vancouver is working with residents, businesses, other organizations, and all levels of government to implement this plan. Vancouver’s vision is to create opportunities today, while building, a strong local economy, vibrant and inclusive neighbourhoods, and an internationally recognized city that meets the needs of generations to come.
