and other associated costs, and the net project cost of $128,625.00 (net HST), be
approved;
4.That Council authorize the Director, Finance & Treasurer to finance the net project cost of
$128,625.00 as provided for in the 2025 Capital Budget, to be funded from the Casino
Reserve;

and,
6.That the appropriate officials of the City of Pickering be authorized to take the necessary
actions as indicated in this report.
Executive Summary: The purpose of this report is to obtain Council approval for
consulting and professional services for the design of the Dunbarton Indoor Pool (DIP) Roof
Replacement and Foundation Leak Repairs. The DIP roof must be reviewed by a professional
engineer annually because it is supported by reinforced autoclaved aerated concrete (RAAC).
RAAC has been identified by the Ministry of Education as requiring investigation, assessment
and management strategies, and ordered removed from its existing facilities due to inherent
risks, including the possibility of sudden structural failure. The 2024 professional engineering
review, conducted by Barry Bryan Associates (BBA), concluded that the current RAAC
(Siporex) system supporting the roof over the natatorium at Dunbarton Indoor Pool is
approaching or at the end of its serviceable life span and will require replacement.

Leak Repair
Professional building sciences consultant, Read Jones Christoffersen Limited (RJC), was also
retained in 2024 to review a through-wall leak at the basement level. RJC concluded that the
leak was primarily related to the lack of an effective waterproofing barrier/membrane on the
exterior side of the building foundation wall and that deterioration does not appear to be
affecting the overall structural capacity of the wall at this time; however, deterioration is
expected to continue and accelerate over time if an effective waterproofing system is not
installed and through-wall moisture ingress is permitted to continue.
BBA’s scope of work will include detailed investigation and analysis of existing supporting
structure to determine the best approach for replacing the existing roof within the existing
bearing capacity of the rest of the building. They will then prepare all required design and
construction documents sufficient to obtain the necessary building permit and issue the project
for procurement. BBA will also support City staff during the construction phase by providing
contract administration services, inspecting the work for conformance with their designs,
reviewing shop drawings and serving as payment certifier.
In accordance with Purchasing Policy Item 10.03 (c), the Manager may obtain the services of a
particular consultant selected by the initiating Director without going through a competitive
process. Where the funds are available in the approved budget and the project or annual cost
of a consulting or professional service assignment is expected to be above $50,000.00 is
subject to the additional approval of Council.
BBA is a professional architecture and structural engineering firm with existing extensive
experience and project history with the roof replacement project at DIP and with RAAC
replacements. They can complete the design in an accelerated timeframe, allowing the
replacement work to proceed in 2025, whereas requesting proposals from other consultants to
provide the same services would require several months for procurement and award, plus time
to become familiar with existing conditions, delaying repairs until next year.
BBA has provided a fee proposal of $95,000.00 for consulting (design and construction
contract administration) services related to the DIP roof replacement and foundation leak
repairs. Upon careful examination of the proposal, the Operations Department recommends
the approval of the fee proposal in the amount of $107,350.00 (HST included) for a total net
project cost of $128,625.00 (net HST).
Relationship to the Pickering Strategic Plan: The recommendations in this report respond
to the Pickering Strategic Plan Priority of Advocate for an Inclusive, Welcoming, Safe &
Healthy Community.

Discussion: The purpose of this report is to obtain Council approval for consulting and
professional services for the preparation of the detailed design of the roof replacement and
foundation leak repairs at the DIP. The DIP was constructed in 1971, renovated in 2008, and
miscellaneous repairs were completed in 2015. The pool roof structure is constructed of
Siporex roof decking spanning between laminated timber beams. Siporex is a type of RAAC.
The Ministry of Education issued a 2023 memorandum stating that buildings that contain
RAAC shall investigate, assess and have a management strategy for the RAAC, including use
of specialized professional engineering services. In many cases, the product is being removed
altogether because of risks associated with potential sudden structural failure.
Professional structural reviews were performed in 2020 and 2023 by 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.
Project Cost under (over) approved funds by $1,721,375.00

Leak Repair
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 Siporex
structure. Ponding can freeze during colder seasons. Combined with a full snow load, this
added weight could cause failure of the roof deck or supporting structure. Accordingly,
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 current Siporex system is
approaching or at the end of its serviceable life span and will require intervention. Given the
age and condition of the building, full replacement is recommended.
As part of the 2025 Capital Budget, capital project C10210.2501 Dunbarton Pool Roof &
Structure Replacement was approved to replace the flat roof, roof structure and other related
components. Single sourcing BBA, who already have extensive experience at DIP having
conducted professional structural reviews and annual roof inspections, and with RAAC
replacements and foundation repairs, represents good value for money since they already
have all the background information and will allow for an accelerated design process and
complete construction in 2025, subject to any unforeseen circumstances revealed during
design.
Completing construction in 2025 will allow the roof to be replaced, foundation to be repaired
and the life of the facility to be extended before the next winter season. Otherwise, the roof and
foundation condition will continue to deteriorate, increasing maintenance and operating costs,
and may cause negative impacts to staff, stakeholders and residents. BBA are uniquely
positioned to deliver the design within an accelerated timeframe. Standard procurement
models can take several months to complete and award, subsequently requiring additional
time for a different consultant to become familiar with affected systems and site conditions.
In accordance with Purchasing Policy Item 10.03 (c), the Manager may obtain the services of a
particular consultant selected by the initiating Director without going through a competitive
process. Where the funds are available in the approved budget and the project or annual cost
of a consulting or professional service assignment is expected to be
(c) above $50,000.00 is subject to the additional approval of Council.
BBA has provided a fee proposal of $95,000.00 (HST excluded) for consulting (design and
construction contract administration) services related to the DIP roof replacement and
foundation leak repairs. Upon careful examination of the proposal, the Operations Department
recommends the approval of this fee proposal in the amount of $107,350.00 (HST included)
and that the total net project cost of $128,625.00 (net HST) be approved.
