Secondary Plant Upgrades, New Tertiary Treatment Facility, New Chlorine Contact Tank and Modifications to Red Hill Creek Located at the Woodward Avenue Wastewater Treatment Plant

Scope

Renovation of a water / sewer project in Hamilton, Ontario. Completed plans call for the renovation of a water / sewer project. The following bidders have been prequalified: - Maple Reinders Constructors Ltd. - Joint Venture with Ball Construction Ltd. - North America Construction (1993) Ltd. - Joint Venture with Reimar Construction Corporation o/a Reimar Forming & Construction - Graham Construction and Engineering LP (by its general partner Graham Construction and Engineering Inc.) - Joint Venture with Harbridge and Cross Limited Secondary Plant Upgrades and New Tertiary Treatment Facility (TTF): Secondary Plant Upgrades include but are not limited to: - The south plant secondary treatment has a current aeration volume of 22,000 m3. Under this project it will be increased to 41,100 m3 to achieve longer solid retention time and year-round nitrification. The configuration of the aeration tanks will change from current complete mix to plug flow. - In addition to the tank upgrade work, nearly all mechanical and electrical equipment will be replaced, including but not limited to, air headers, air distribution system, diffusers, valves, instrumentation. - The south plant clarifiers will also be expanded. There are currently four units with a total surface area of 4,860 m2, which will be expanded to six units with a total surface area of 7,290 m2. All six tanks will have new chain-and-flight systems along with other mechanical, instrumentation and electrical upgrades. - A fourth aeration blower to be installed in the existing blower building along with upgrades to the blower building, Heating, Ventilation, and Air Conditioning (HVAC), electrical, and architecture. - Miscellaneous upgrades to the south plant including mechanical, electrical, and instrumentation and control (I&C) upgrades. Mechanical, HVAC, architectural, electrical and I&C upgrades to existing return activated sludge (RAS) building. - Associated tie-ins. - Staged start-up and commissioning of this Project component. The scope of the TTF includes but is not limited to: - Construction of a new disk filtration based TTF. The TTF will have 10 trains, each with 24 pre-purchased disk filters sized to treat flows up to approximately 63 MLD. Prior to each filter are dedicated flocculation zones and a coagulation zone, which is common to each of two floc/filter train. - The TTF contains chemical storage and dosing facilities, chlorination system for effluent water system and laboratory and office spaces. The new building is fed with new utilities and roads and staff parking surround the building. - Associated tie-ins. - Start-up and Commissioning of this project component. - Civil and landscaping works involving erosion and sediment control, tree removals, clearing, grubbing, topsoil stripping, excavation, offsite fill disposal, yard piping installation, backfilling, compaction, rough grading, fine grading, paving, sidewalk installation, tree planting, landscaping and associated works. New Chlorine Contact Tank (CCT): Works include but are not limited to: - A new final effluent CCT with contact volume of approximately 10,420 m3. - A new influent channel to the CCT from the TTF. - Installation of dechlorination dosing equipment (SBS) in the existing chemically enhanced primary treatment (CEPT) building. - New SBS piping from the CEPT Building to the CCT. - New double-box conduit outfall from new CCT to Red Hill Creek. Modifications to Red Hill Creek: - Modifications to Red Hill Creek are required to mitigate the increased erosion potential associated with the increased daily discharge along an approximate 1 km reach between the existing and new plant outfall. The work will include creek widening, restoration, and integration of energy dissipation features. The Woodward Upgrades Project has received priority funding support from the federal and provincial governments under the Green Infrastructure Fund (GIF) which at this time has a completion deadline of December 2021. Specific schedule requirements may be further detailed within the Request for Tenders. The Project may be subject to certain requirements and conditions which are set out in a contribution agreement between the City and the Government of Canada and the Province of Ontario. The value of this project is estimated to be between $130,000,000 and $160,000,000. Documents and addenda may be obtained at: https://hamilton.bidsandtenders.ca
