The Bonnie Doon Leisure Centre closed its doors in September 2016 for rehabilitation.
Once the facility was closed to the public, further inspection into the state of the building identified more opportunities for improvement which required additional design work.
Adding unplanned work, as well as adjustments to the existing scope for this rehabilitation https://cms.edmonton.ca/cms/Icons/CommandButtons/ok.gifproject, required an updated budget with approval from City Council.
An adjusted scope, budget and schedule for this project was approved in the May, 2017 Supplemental Capital Budget Adjustment (SCBA).
The Alberta Health Pool Standards were revised in 2014 and now mandate the installation of anti-entrapment devices in all pool basins according to the Public Health Act. The existing main drains will be enlarged in both the hot tub and the pool as well as new drains added to reduce pressure at the bottom of the pool to help mitigate the risk of entrapment from suction. These measures are in place to improve swimming safety.
The Bonnie Doon Leisure Centre Assessment, completed in 2016, provided a review of the chemical treatment options. This information guided the City’s decision to move to a saline chlorination system (from a gas chlorination system) to meet the community’s wishes for a saltwater pool. Conversion to a salt water treatment system involves structural modifications, corrosion resistance upgrades for all filtration systems and replacement of the hot tub and pool basin lining and deck tiles.
Additional design plans for this rehabilitation project included an energy audit report which identified opportunities to improve energy efficiency of the building. Recommendations in the report included replacement of the air handling and hot water systems to reduce energy costs.
