Request for Tender No. T2024-1 Page 3
Discussion: The purpose of this report is to obtain authority to award Request for Tender
No. T2024-1 for Rouge Stormwater Management (SWM) Pond Sediment Cleanout to Cardan
Demolition & Excavation Inc.
The City of Pickering hired T.Y.Lin International Canada Inc. (TYLin), formerly known as The
Municipal Infrastructure Group Ltd., in June 2019 to undertake the Stormwater Management
Facilities Asset Management Plan (AMP). The project was awarded through RFP-3-2019.
The AMP has identified the Rouge SWM Pond as the first priority for the City’s maintenance
works plan and, based on the pond’s deteriorated state and a cost analysis, the AMP has
recommended a maintenance and cleanout option for the Rouge SWM Pond restoration. Staff
recommended the Rouge SWM Pond Sediment Cleanout project in the 2023 Capital Budget,
with the intent of proceeding with design and approvals in 2023, followed by construction in
2024.
The Rouge SWM Pond was constructed in 1993 to provide water quality and quantity control
for a 27 hectare drainage area, according to the applicable criteria at the time. The Rouge
SWM Pond services the Bramalea Subdivision which is located northwest of the intersection of
Twyn Rivers Drive and Woodview Avenue, as shown on the Location Map (Attachment 1).
Currently, the southern wet cell portion of the Rouge SWM Pond is full of accumulated
sediment and requires cleanout. Additionally, the hickenbottom outlet control structure is
clogged resulting in an elevated permanent pool and reduced overall performance. The Rouge
SWM Pond no longer meets the minimum water quality objectives according to the Ministry of
the Environment, Conservation and Parks guidelines, and the City of Pickering’s Stormwater
Management Design Guidelines.
Request for Tender No. T2024-1 was advertised on Bids & Tenders on Tuesday, February 6,
2024 and closed on Friday, March 8, 2024 with 18 companies responding. The lowest
compliant bid of $521,898.13 (HST included) submitted by Cardan Demolition & Excavation
Inc. is recommended for approval. The total gross project cost which includes the tendered
amount, a construction contingency, and other associated costs is estimated at $670,011.00
(HST included) with an estimated total net project cost of $603,366.00 (net of HST rebate).
In 2023, TYLin completed the detailed design and approvals for the Rouge SWM Pond
Sediment Cleanout project. Staff recommend continuing with TYLin to undertake the contract
administration, construction supervision and certification of works associated with Request for
Tender No. T2024-1 Rouge SWM Pond Sediment Cleanout project as set out in fee proposal
dated January 9, 2024 in the amount of $75,650.00 (HST excluded). The hiring of TYLin and
its team of sub-consultants, represents good value as they have the necessary project history,
specifically the technical and existing conditions information of the Rouge SWM Pond
Sediment Cleanout project, knowledge and expertise.
Further, in accordance with Purchasing Policy Item 10.03, 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 is subject to the additional approval of Council. The initiating Director
shall submit the Report to Council to obtain approval.
All required pre-conditions of award have been received and approved.
Upon careful examination of all tenders received, the Engineering Services Department
recommends acceptance of the lowest compliant bid submitted by Cardan Demolition &
Excavation Inc. for Request for Tender No. T2024-1 in the amount of $521,898.13 (HST
included), and that the total net project cost of $603,366.00 (net of HST rebate) be approved.
