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...

The arena services the Western Hockey League Vancouver Giants and other professional sports such as NLL lacrosse and basketball, as well as CIS (university), high school and recreational sports leagues, concerts, trade shows, etc. The arena bowl has approximately 5,300 seats including corporate suites and a concourse area with concessions. The facility was constructed in 2009 so it is relatively new. Upon our initial assessment the existing lighting system failed to meet requirements for sporting events with issues being low lighting levels and poor uniformity for hockey and, to a greater extent for lacrosse due to the low reflectance of the playing surface. The existing lighting also had a negative affect on TV broadcast quality. After considering all options, it was determined that the best solution was to replace the existing 108 fixture metal halide system with an LED lighting system. DMD undertook lighting design, defined the required lighting criteria, developed performance specifications, developed budgets, reviewed bids, provided technical support and assisted with system testing. Challenges overcome included re-use of existing wiring and infrastructure to reduce cost and the very tight time frame of just over one week to remove existing lighting and install new LED lighting. Special features of the new LED lighting included: Full DMX system control with touch screen lighting controller Fully dimmable system Colour temperature changing capability from 3500K to 5800K Colour changing event lighting system to create various theatrical lighting effects 10 year supplier warranty The end result was lighting to near NHL standards with an estimated annual power savings of 400,000 kWhr per year. ...
