Requirement:Parks Canada requires a Contractor to upgrade the Bathing Pavilion’s existing radon extraction system at the Cave and Basin National Historic Site, which primarily consists of upgrading mechanical systems in the basement of the building and carrying the radon fumes, through extensive ductwork, up to the roof of the Galletly Building for proper venting into the exterior environment. This intervention is meant to improve the capacity and flow of the radon extraction system. An additional proposed upgrade, a door location change, will better redistribute air circulation in the North Belvedere.See specifications and drawings for further details on the requirement of this project.To assist with bonding and insurance requirements, this project is estimated at a value between $100,001 > $ 250,000, Taxes extra.Bidders’ ConferenceA bidders' conference will be held via teleconference on August 19, 2021.
