We are excited to announce that we have started work on the new North East False Creek Project! This project involves the removal of the Georgia Street Viaducts and the major works surrounding the site. Within the project limits, 5% of the City of Vancouver traffic signals will be impacted (42 plus or minus) and about 6 km of street lighting. The project also involves dynamic message signs, traffic management systems and communication duct design. We are looking forward to working with the City of Vancouver to help create a new and improved viaduct area. Stay tuned for updates on the progress of this...

The completed bridge located in Trail, BC runs over the Columbia River. The bridge was designed by COWI features single-leg tower pole masts , a deck, cables, and lighting. The bridge is 305 metres (1000 feet) long; one of the longest pedestrian suspension bridges in North America. DMD undertook design of the electrical system which included LED walkway lighting and the design of full colour changing LED theatrical type lighting system with DMX control to highlite the structure and cables. The colour changing bridge lighting was designed using rendering software to provide the cleint with photomertically correct lighting effects in the actual existing night-time setting (see rendering below). The colour changing LED system was not installed as part of this work however is being considered for a later...

DMD have completed and issued the City of Vancouver street lighting and traffic signal design and construction standards which will be published by the City in early 2017. The standards define specific design and construction requirements for street lighting and traffic signals in the City of Vancouver. DMD and City staff worked in collaboration to develop these very detailed...

A building proposed by a developer was adjacent to a transmission corridor and maintaining the required clearances from the transmission to the building became an issue. Due to environmental electric fields being present in and near a high voltage transmission corridor, an adequate setback must be maintained to achieve the safety of workers, maintenance staff and the general public. With the proposed building height and a transmission ROW with two 500kV lines, a recommended setback of the building was provided by a table in the utility provider’s technical guideline. As dictated by the technical guideline, if the building is proposed at a closer setback than allowed for in the guideline, a detailed electric field study must be undertaken and submitted to the utility for review. DMD undertook the required electric field study to determine the minimum permissible distance from the closest conductor in the utility Right of Way (ROW) based on tolerances from IEEE and the utility. For the study we used a Corona and Field Effects software to determine the environmental electric field. Our analysis showed a potential reduction in building setback to meet the developer’s requirements while still maintaining the safety levels required of IEEE and the local...

The Pacific National Exhibition (PNE) is a non-profit organization which hosts an annual summer fair in Vancouver, British Columbia, Canada. Other than the fair, Hastings Park is also the home of Playland (Amusement Park), Hastings Park Horse Race Track, the Pacific Coliseum (former home of the NHL Vancouver Canucks), the PNE Forum, and the PNE Agrodome. It was formerly the site of Empire Stadium, which has been demolished and replaced with a public soccer field. In 2011 the City issued the Hastings Park / PNE Master Plan – A New Vision for Hastings Park to transform Hastings Park into a greener, year-round destination for park use, culture, sport and recreation, pleasure, and fun. Highlights of the plan include relocating and expanding Playland, connecting to Burrard Inlet, adding park space and natural habitats, creating celebratory spaces, and acknowledging Hasting Park’s history. Early in 2015 DMD were retained to undertake a review of the existing electrical, communications and lighting infrastructure and develop a conceptual design and cost estimate for upgrades within the context of the Master Plan and future needs. DMD undertook a complete review of the existing 4kV and 12.5kV electrical system throughout the entire 150 acre park. The existing system included various sub-stations, transformers, overhead and underground feeds, telecommunications feeds to venues and buildings throughout the site. DMD were able to extract data from BC Hydro’s DAD system which was used to define existing demand and peak loads along with overall power consumption and rate schedules. We reviewed rate schedules and costs in detail and provided a complete assessment. Also included is a complete assessment of the telecommunications system...

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...
