DIP was constructed in 1971, internally renovated in 2008, and miscellaneous repairs were completed in 2015. The pool roof structure is constructed of reinforced autoclaved aerated concrete (RAAC) roof decking spanning between laminated timber beams. The Ministry of Education issued a 2023 memorandum stating that buildings that contain RAAC shall require investigation, assessment and a management strategy for the RAAC due to concerns for potential spontaneous structural failure. In many cases, the product is being removed altogether because of risks associated with potential sudden structural failure. 4.1 Project Background Professional structural reviews were performed in 2020 and 2023 by Barry Bryan Associates (BBA), concluding that the structure was in good condition at the time of inspection. The 2023 report additionally noted that professional engineering inspections of the DIP roof structure be conducted annually. During the 2024 annual inspection, also conducted by BBA, they concluded that immediate repairs were required due to large ponding on the pool roof, supported by the RAAC structure. Ponding could freeze during colder seasons. Combined with a full snow load, this added CS 08-26 March 23, 2026 Page 4 weight could cause failure of the roof deck or supporting structure. Accordingly, immediate emergency repairs were conducted in fall 2024 as authorized in Resolution #612/24 (Report OPS 21-24). The 2024 annual inspection also concluded that the RAAC system was approaching or at the end of its serviceable life span and required intervention. Given the age and condition of the building, the process for full roof replacement was initiated. Design was authorized in Resolution #693/25 (Report OPS 03-25). 4.3 Procurement Process Contractors were prequalified through RFSQ2025-5, to ensure that bidders would have sufficient expertise in the handling of these types of structures, and depth of resources required to undertake sensitive work in proximity to Dunbarton High School. The pool roof is physically connected to the school. Staff have coordinated efforts with the Durham District School Board (DDSB) during the design phase to minimize potential risk or disruptions to the school as a result of this work. Coordination will continue in the construction phase. The award of this contract now will help ensure that required materials will arrive on site in advance of construction commencing in early July. The work is expected to be completed by October 2026. Request for Tender No. T2026-1 was advertised on the City’s bids&tenders portal on January 14, 2026, and closed on February 13, 2026. Three contractors pre-qualified under RFSQ2025- 5. All three pre-qualified proponents submitted bids. Subject to receipt and approval of all pre- conditions of award required in accordance with the bid document, the lowest compliant bid submitted by Triumph Roofing & Sheet Metal Inc. in the amount of $2,765,836.80 (net HST) or $3,071,340.00 (HST included), is recommended for approval. The total gross project cost is estimated to be $3,719,508.00 (HST included), and the total net project cost is estimated at $3,349,532.00 (net of HST rebate). 4.4 Service Disruptions and Communications with DDSB Dunbarton Pool is owned by the City of Pickering and operates from 5:30 am to 9:30 pm from September to June, with reduced hours of operation during the summer months. The pool accommodates swimming lessons, accommodating 2,530 participants in 2025 with a waitlist of 614 people. The Pickering Swim Club and Masters Swim Club rentals accommodate approximately 250 swimmers. Four hours of open swim and lane swim are also offered weekly. To accommodate the service disruption due to construction, learn to swim programs will be added on Sunday mornings at Chestnut Hill Developments Recreation Complex (CHDRC). Some lane swim times will be cancelled at CHDRC to allow aquatic certification courses. These classes provide required training for employment as a lifeguard or an instructor. The City has an existing Reciprocal use of Facilities Agreement (CS 27-25) with the DDSB that allows for shared use of parks and facilities in Pickering. With respect to Dunbarton Indoor Pool and Dunbarton High School, the arrangement allows for the Board to use the pool for CS 08-26 March 23, 2026 Page 5 educational, athletic and recreational purposes from Monday to Friday during the school day and year. Dunbarton High School specifically uses the pool for gym classes, swim team practices and outdoor education water safety orientations. In exchange, the City uses the Dunbarton High School gym to provide recreation programs to residents including volleyball, badminton and a summer sports camp that has operated in this location for decades. During this service disruption, City programs will be relocated to Eastshore Community Centre for summer 2026. Staff have held several meetings with the Principal of Dunbarton High School and the DDSB Project Supervisor through project design and planning to ensure that service disruption to the school is minimized. Meetings and communication will continue through construction. Attachment: None.
