CDA Winnipeg event a huge success!

The CDA 2020 Organizing committee would like to thank all those individuals in Winnipeg who made time on January 28 for the local event at the Stone Angel Brewing Co. 

More than 70 Individuals attended last week’s event where attendees were treated to two technical presentations.  Conor MacGillivray of Manitoba Hydro presented “Slave Falls Generating Station Pier 1 Repair” and Brian Earl of Manitoba Infrastructure presented “Deloraine Dam Rehabilitation”.  Following the presentations, individuals were able to catch up with friends and colleagues.

CDA would like to thank Ben vanderHooft for planning and coordinating this event.

Slave Falls Generating Station Pier 1 Repair
Slave Falls in an electrical generating station along the Winnipeg River. Originally built in 1930, it had been operating for almost 80 years when significant deterioration was discovered in one of its sluiceway piers. While preparing to begin work on a repair, further investigation found that the problem was far more serious than originally thought. This investigation sparked an urgent effort to improve the safety of the structure using a concrete containment wall. This presentation discusses the design and construction of that containment wall as well as possible root causes of the deterioration and their potential impacts on the future of Slave Falls.
 
Presenter - Conor MacGillivray
Conor MacGillivray is a structural engineer with the Manitoba Hydro Generation Design Department with over five years of experience in engineering design, analysis, and construction projects. Conor worked on the design and construction of Slave Falls pier 1 containment wall and is currently involved in the Slave Falls scope development project to determine the future of the station. In his time at Manitoba Hydro he’s worked on the Keewatinohk Converter Station and Keeyask Generating Station and has been the lead structural engineer on a variety of projects at sites across Manitoba. 

Deloraine Dam Rehabilitation
Turtlehead creek (Deloraine) Dam was constructed in 1962 to create a drinking water supply for the Town of Deloraine. The dam consists of a 300m long, 15m high earth embankment with a timber chute spillway and riparian outlet.  Studies are currently underway to determine the most appropriate and cost effective replacement options. The presentation will discuss the unique and challenging aspects of the project including the timber chute and downstream hydraulic impediments, while highlighting criteria and principles used from the Canadian Dam Association guidelines.
