Standards

DMD prepare numerous standards for various Municipalities, Cities and governments. These standards range from nationally published standards and certification courses to standards for provinces and states and Cities and municipalities. Studies and white papers range from specific to general in nature.

DMD electrical specialists have assisted communities and local and regional transportation agencies develop standards that streamline the design process, improve quality and consistency, and simplify maintenance needs. Our seasoned staff works closely with owners and other stakeholders to ensure that deliverables provide needed guidance without compromising the need for innovation and adaptation for special situations.

National Publications include:

Transportation Association of Canada Roadway Lighting Design Guide

The The Transportation Association of Canada (TAC), Roadway Lighting Design Guide was originally published in 1983 and was deemed in early 2000 to be outdated and in need of replacement. Through a Canada wide competitive selection process, the DMD team was selected to prepare the new Roadway Lighting Design Guide. The nearly 500-page design guide covers all aspects of roadway lighting design including vision fundamentals and concepts, obtrusive lighting, planning and design process, system components and common elements, standards and codes, computer applications, maintenance, roadways and interchanges, intersections, roundabouts, crosswalks, tunnels, toll plazas, off roadway facilities (parking lots, pathways, etc.), signs, streetscapes and work zone/temporary lighting. In preparing the document, design standards and design practices from North America, Australia, New Zealand and Europe were researched. The majority of the Guide is, therefore, based on existing recommended practices of the Illuminating Engineering Society of North America (IESNA) and the Commission Internationale De l'Eclairage (CIE).

The DMD team included specialist sub-consultant firms such as Lighting Sciences of Scottsdale, Arizona and Parsons Brinckerhoff of Boston, Massachusetts. The project was completed on time and on budget.

IMSA Level 2 Roadway Lighting Certification Course

We prepared a 200+ page national roadway lighting certification course for the International Municipal Signal Association (IMSA). The course deals with all aspects of roadway lighting and through the IMSA one can obtain certification based on the course material. The certification is aimed at both the engineer and those operating a street lighting system (i.e. City, Municipality, etc). The document includes latest design and maintenance practices described in text with over 200 figures and illustrations, 100+ question examinations, a moderator’s guide and a 2 hour oral DVD outline. The project was completed on time and on budget.

IESNA RP-8 - American National Roadway Lighting Recommend Practice

Involved updates to Illuminating Engineering Society of North America (IESNA) document related to roadway and outdoor lighting. Current documents in development include adaptive lighting, revisions to photo-controls document and revision to maintenance standards document. Don McLean of DMD is working with industry expert in the development of the next edition of RP-8.

CSA C653 Luminaire Performance Standards

DMD staff is on the committee developing performance and efficiency standards for cobra head luminaires for CSA. The standard defines a benchmark for luminaries photometric performance, allowing design designers to evaluate and design with energy efficient products. On this project DMD staff worked with industry experts to develop the CSA C653 document.

Electrical Maintenance Standards

The Ministry of Transportation required the electrical maintenance of their infrastructure be privatized throughout the entire Province of British Columbia. The owner wished to pursue a "performance based" method (also referred to as "outcome based") as opposed to the traditional "method based" contract.

The assignment included a world wide search of performance based contracts and a summary of those methods. The assignment also included research and recommendations for corrective and preventative maintenance tasks and frequencies as well as a guide for a quality management systems, a list of the various assets and the preparation of detailed technical specifications.

DMD also completed detailed specifications and procedures for commission traffic signal controllers and signal start-up.

US Federal Highway Administration Lighting Handbook

The most current edition of the FHWA Roadway Lighting Handbook (IP-78-15) was published in 1978. An update was needed to inform practitioners of the fundamentals such as theory, technology, standards, and federal-aid guidance pertaining to roadway lighting. The national roadway lighting standards commonly referenced by practitioners are the AASHTO Roadway Lighting Design Guide, the TAC Roadway Lighting Design Guide and the IESNA RP-8 American National Standard Practice for Roadway Lighting. The updated document will present the above mentioned fundamentals and guidance on the FHWA roadway lighting policies.

The objective was to produce a professionally written, well organized, and user friendly handbook that concisely describes roadway lighting fundamentals (not design) and guidance on FHWA roadway lighting policies. The handbook is a resource to guide practitioners in the effective use of roadway lighting as a countermeasure to reducing the number of serious injuries and fatalities on roadways, especially during nighttime.

City of Lethbridge Street Lighting Standards

The City of Lethbridge required a Roadway and Community Lighting Manual which will include guidelines for the planning, design, operations, maintenance and construction of the City’s street and community lighting system. In addition, updates from the 2006 Edition of the TAC Guide for the Design of Roadway Lighting will be incorporated where applicable within the manual. The City wished to reduce power consumption therefore the project also included a review and cost benefit analysis of LED’s and adaptive lighting controls to be incorporated into the Lighting Manual.

City of Edmonton Street Lighting Standards

The City of Edmonton’s street lighting design, construction and material standards were dated and in need of a major re-write. They also were written such that many sections had duplicated information which made the document hard to maintain and hard to locate information.

Through a competitive process DMD and Associates Ltd. were retained. The design standards have now been re-written as a supplement to the TAC Roadway Lighting Design Guide making for easy usage. Construction standards involve updating existing standard drawings, preparing new standard drawings and a new written specification to cover all elements of street lighting construction. Material standards were also developed for key materials such as luminaires, poles, bases, etc., along with an approved product list and process for suppliers to have their products approved.

The standards were successfully completed and refined dealing with follow-up comments and a few required revisions. The end result was a concise standard defining process and requirements for both design and construction. In fact the standards went from over 300 pages to under 100 pages with significantly more content covered using far fewer words.

Ministry of Transportation Electrical and Traffic Engineering Design Guide

The Ministry Electrical and Traffic Engineering Design manual for roadway lighting and traffic signals forms the basis of standards used throughout the Province of British Columbia. This document includes hundreds of pages of text with many diagrams and figures. The design manual referenced industry standards such as those by the IESNA and included numerous tables, diagrams and figures to clearly define requirements. DMD were retained to update the document which was originally produced in the late 1990’s. The work is ongoing with final draft submitted awaiting owner comments. Don McLean of DMD is the lead on the project and original author of the Ministry’s Design, Construction, Material and Maintenance standards.

Master Municipal Specifications Design Criteria and Green Design Guide

DMD rewrote the Master Municipal Construction Documents Association (MMCDA) Lighting and Signals Design Standards documents used by Municipalities and Cities throughout British Columbia. Also included is the development of “Green Design Guidelines”. The project involves researching of current practices, development and updating of design criteria and standards and production of a new document.

City of Edmonton Light Efficient Community Policy

The goal of this project was to develop a Light Efficient Community Policy for all City owned lands and properties including all outdoor road right-of-ways, building facades and exteriors, outdoor facilities, parklands and other City owned lands. This project involved research, investigation and recommendations of best practices for the efficient use of lighting with respect to light pollution, power consumption, reduction in green house gases, and provisions for public health and safety. The project involves the City, Edmonton Federation of Community Leagues, Light Efficient Communities Coalition (LECC) and other stakeholders and special interest groups.

The project included extraction of GIS lighting data and an assessment of existing lighting along with field lighting measurements. A map was developed showing existing illumination levels and developed a strategy to prioritize street lighting upgrades to address identified deficiencies, taking into account capital, operating and maintenance cost. To do this we obtained GIS data from the City to define typical light pole spacing, mounting heights, road types, widths, etc and undertook lighting calculations using photometric files assumed to match those luminaires which exist.

City of Hamilton Comprehensive Outdoor Lighting Study

In October 2008, the Task Force on Cleanliness and Security in the Downtown Core (TFCSDC) completed a study entitled: Protecting the Future: A Safety and Security Audit of the Downtown Hamilton Improvement Project Area. The results of this study concluded that improvements to the existing downtown lighting could contribute directly to improving the sense of security and reducing the fear of crime. The City therefore developed a terms of reference and issued a request for proposal to retain a firm to deal with these and other issues. Through a competitive request for proposal process in the fall of 2009 the team of DMD was retained and developed a comprehensive lighting study. The goal of this project was to investigate and validate the reasoning for the requirement of lighting (or not lighting), develop lighting guidelines and review ways to save power.

The project included numerous stakeholders, City council meetings and presentations, meeting with local BIA’s, meeting and discussions with local police and CPTED officials. The stakeholder groups included many sectors representing different goals and opinions. We organized meetings with over 30 in attendance and over the course of the project developed the trust and support of the Stakeholders and BIA groups.

The final report included the following information:

• General: Introduction, theory of lighting and basic issues.
• City-Wide Outdoor Lighting Review: Research, standards, existing condition assessment and measurements of lighting levels, police and stakeholder input and recommendations for the following applications within the City including: Sidewalk Lighting, Rural Roadway Lighting, Urban Intersections, Rural Intersections, Alleyways (Commercial and residential), Parks, Parking Lots, Plazas.
• Recommendations for lighting hardware, maintenance practices and implementation strategy. Also included was a review of energy saving lighting technologies such as LED’s and adaptive lighting.
• Downtown Area: Included an assessment of existing levels and recommendations for roadways, intersections, sidewalks, parks, plazas and parking lots in the downtown. Also included were recommendations for aesthetic lighting for building exteriors.
• BIA Lighting: Provided a review of existing lighting within fourteen (14) BIA’s.
• A map was developed showing existing illumination levels and developed a strategy to prioritize street lighting upgrades to address identified deficiencies, taking into account capital, operating and maintenance cost. To do this we obtained GIS data from the City to define typical light pole spacing, mounting heights, road types, widths, etc and undertook lighting calculations using photometric files assumed to match those luminaires which exist. The final report was developed and 20 bound copies issued to the City. Following submission of the document a Power Point Presentation was made to City Council. The City is now using the information in this report to adopt a Comprehensive City-Wide Lighting Policy. The project included extensive consultation with stakeholder groups, review, investigation, research and recommendations.
