Bonvital Pool Replacement of Pool Filtration System

The Bonivital Pool is a City of Winnipeg facility which required a replacement of the pool filtration system. The changes were to be scheduled during the pool maintenance shut down period and limited to a 6 month period. The existing sand filters were  disconnected and new sand filter installed.  New water supply piping, related valves and new drainage piping was to be installed. All equipment was to be commissioned and start-up done.     

The challenges of this project were due to the schedule constraints. As much pipe as possible was prefabricated at our shop. We stayed in contact with our suppliers of filters to confirm delivery would be on time.  On site meetings complete with consultants and Owner were held to review install layout prior to commencing.  

By doing as much prefabrication in our shop we eliminated time and space constants of the site.  We had a more accurate control of the schedule as we know how much was left to fabricate and install on site. 

Pam Am Pool Domestic Hot Water System Replacement

Winnipeg’s Pan Am Pool is one of the premier aquatic facilities in Canada and meets international standards to host worldclass aquatic events.

The domestic hot water system replacement project consisted of demolition of two hot water tanks and associated piping, pumps and controls. Plus, the supply and install of 2 new domestic water boilers complete with piping, venting, controls and associated systems. Two new pumps were installed for the pool heat exchangers and modifications were done to the existing combustion air units.  The boiler rooms at the top of the North and South shafts were fire rated. 

Due to site conditions change orders were required for additional control points for monitoring agencies. Valves that did not hold had to be replaced and firestop was added to existing pipe penetrations.

Project risks included time constraints of: working in a public used building with reopening dead lines; system functional problems due to air pressure and scheduling work hours taking public use hours into consideration. 

Weekly meetings were held with the department supervisors to develop a schedule around the facilities requirement. A building survey was done to determine firestop required for proper building pressure. 

Churchill Marine Observatory Phase 2

The Churchill Marine Observatory is a University of Manitoba facility located in Churchill, Manitoba.

Scope of work of this project was the construction of a new sea water intake and supply line to the marine observatory including utilidor, water intake lines, discharge lines and pump house. Pumping equipment was installed to bring water to and from the Churchill Marine Observatory Research Facility.

Working in a remote northern location caused challenges with climate and access.  Transportation to the location was by train or air.  We were able to complete our work during the summer months and coordinated closely to limit the number of flights required to transport our people to the remote site. One of the key elements was efficiently transporting material and equipment by train in a timely manner so that it was available when our people were on site. Planning and accuracy on material take off was essential as sending material by air freight would have been an expensive option.  This was a key to keep cost under control.
