DMD, as part of the BA Blacktop design-build team, were awarded a 2015 Canadian Design-Build Institute (CDBI) Award of Excellence for the Roberts Bank Rail Corridor (RBRC) Combo Project. The RBRC Combo Project was an $88 million dollar design-build project delivered by the City of Surrey which included three new grade separated overpass structures spanning an active rail line and the high traffic volume Highway 10 corridor. The main goals of this project was to improve traffic safety, traffic flows and emergency vehicle access while reducing traffic delays and train whistles due to the at grade train crossings. DMD provided the Electrical Engineering for the project, which included 8 traffic signals, ITS ducting across all bridges, approximately 6km of roadway lighting along with some pathway lighting, all to meet the required Ministry of Transportation, City of Langley, Township of Langley and City of Surrey...

The project involved the conversion of over 22,000 Street Lights in Windsor Ontario. DMD developed a product selection specification that rated and reviewed products from major suppliers in a point score based system. We performed lighting calculations in order to define the appropriate luminaires to meet lighting level and maximize efficiency. The conversion is expected to provide higher than expected energy savings due to our extensive review and assessment...

The basis of a good functioning signalized intersection is a deep understanding of how the traffic controller equipment works from the ground up. Understanding all the available functions this equipment offers to better service the pedestrians, cyclists and vehicles is what DMD does best. DMD have tested, set-up, and commissioned over 75 traffic signal controllers over the last 7 years and as such have gained extensive knowledge and understanding of controllers and their operation. Our services include shop testing and programming along with testing, set-up and commissioning in the field. This process has improved implementation and reduced delays. In addition documentation provided such as “as built” controller wiring diagrams and hook-up instructions has aided maintenance and field troubleshooting. We prepare signed and sealed clearance calculations to ITE and municipal standards for every intersection commissioned for safe operation. Our expertise also includes the commission/testing of vehicle detection systems, which include inductive loop, video and radar detection, accessible pedestrian systems (APS), uninterruptible power supplies (UPS), pre-emption systems, radios, IP camera’s and switch configurations for traffic communication...
