INNOVATION July-August 2014

2O13 2O14 PROJECT HIGHLIGHTS

CORIX Energy Transfer Station Corix Multi-Utility Services owns and operates the regulated (BCUC) district energy system which services the UniverCity residential community located on Burnaby Mountain. District energy systems use a central energy plant to produce thermal energy utilizing hot water, which is distributed through a network of underground pipes, to Energy Transfer Stations (ETS) located in each building. The Corix pre-packaged ETS is a pre-engineered, tested and shop-assembled mechanical system. It includes all necessary heat exchangers, valves, piping, appurtenances and instrumentation for a complete and operable system which efficiently provides domestic hot water and space heat to residential and commercial units. There are several pre-packaged ETS’s currently in operation at UniverCity. Professionals involved: Lynda O’Donoghue, EIT.

Runway 12 Improvement Project – L.F. Wade International Airport The L.F. Wade (Bermuda) International Airport Department of Airport Operations (DAO) assessed the Runway 12 aircraft approach to confirm that ICAO-required obstacle clearance distances were being met. The DAO found impending

encroachment and decided on a long-term solution to displace the threshold by 176 m, which required replacing the threshold and approach lighting systems. The DAO identified other upgrades to be undertaken, such as installing new runway centreline lighting, replacing the aged runway edge lights and upgrading signage. Associated Engineering designed the systems and recommended using LED lighting for the high-intensity runway edge and inset centreline lights. Using LED lighting has reduced the power consumption of the airfield by approximately 65%, a significant amount given the high power rates in Bermuda. Project team: David Anderson, P.Eng.; Doug Falkins, Eng.L.; Lester Marr, P.Eng.; Sang Chung, P.Eng. (Associated Engineering).

TUF – Lugger Lite with Load Cell

DCD Design & Manufacturing, to complement their new line of gas and electric winches rated to 2,200 lbs, has developed a load cell data logger and application for Android and Windows devices. The electronics pack and load cell attach to the back of the winch support and connect to a phone, tablet or laptop via USB or wirelessly by a Bluetooth connection. The app is customizable by the end user, allowing for metric or imperial settings, load threshold limits, a variable data collection rate between 1 and 10 data points per second and automated email alerts if the user-established threshold limit is exceeded. Data can be saved to the device and easily exported to a CSV file format. Project lead: Chris Pudlak, P.Eng.
