Renovation of a municipal facility in Gatineau, Quebec. Completed plans call for the renovation of a municipal facility.

Complete important repairs to the Cooling Tower #2 & #3 (GOC00933-30-180-000002 and GOC00933-30-180-000003 located on the 19th floor penthouse). The hot water basins of each cooling tower and the surrounding casings are leaking and they need to be replaced, including lids, nozzles, baffles, connecting pipe gaskets, hardware, nuts and bolts. Piping supports should also be replaced as the lack of support is putting an added stress on the basin connections. Because of those deficiencies, excessive spray of water droplets is occurring which is a great risk for legionella propagation. Also, the leaking basins drip down beside the cooling towers which accelerates the deterioration of exterior materials that were not protected by a membrane in the past. Review of the previous inspection reports shall be referenced before performing any repairs. The recommendations in previous reports suggest that the use of Stainless Steel 316, 14 ga. for the construction material of the basins and lids. The hardware should also be Stainless Steel 316. The contractor should ensure that all components are suitable for the system operating parameters and conditions. All work requiring a shutdown of the cooling towers to be completed in the shoulder seasons, when the demand is at its lowest. These shutdowns shall be coordinated with the maintenance team. Complete important repairs of cooling tower #1 (GOC00933-30-180-000001) located on the 19th floor penthouse of 25 Eddy. The project consists of repairing all cooling tower #1 deficiencies identified in reports T19322- rapport sur tour d'eau CWT and 25 Eddy Repair Cooling Tower. Deficiencies include, but are not limited to, hot water basin leaks, defective pressure regulating valves, collapsed wet-deck fills, inappropriate bearings, lack of vibration protection and motor in bad condition. At this moment, the fills are sagging down thus causing gaps, resulting in excessive spray of waters droplets, loss of efficiency and excessive consumption of water and chemicals. As reports suggest, the temperature rating of the fills in the past (2012) was not properly chosen for the water temperature of a heat recovery plant (high condensed water temperature). The consultant shall perform an in-depth investigation to identify all cooling tower issues. This project will oversee the replacement of the fills with correct temperature ratings and installation, repairing the hot water basin spray system (nozzles) and all other deficiencies. Reports detailing the cooling tower #1 deficiencies are available for reference. Work shall be done in shoulder seasons, when the load is at its lowest. Shutdown shall be coordinated with building operations. This project consists of installing a cooling tower basin sweeper piping system that will dislodge the sediments on the basin surface and prevent future buildup. The system will require a separator/filtration system to remove the pollutants and dirt from the water.
