Large waves due to coastal storms (wind-waves) or tsunamis (in the form of solitary waves) will be simulated within the Multi-Hazards Simulator (MHS) using a wave generator. The wave generator consists of a flat "paddle", which is a 1.5 m wide by 1.5 m tall rectangular plate that is hydraulically driven back and forth by a piston to generate a series of water waves. The wave generator action is controlled such that various wave trains can be created, regular or random, with controlled wave periods and amplitudes. Convenient software included with the system is used to specify the wave train. The control system also utilizes water wave sensors placed onboard the wave generator and within the MHS to adjust the piston action in real-time. This should enable the system to dampen reflected waves while continuing to generate the desired wave train. The MHS Flume is built with a concrete wall on the south side and as a steel frame construction as the north wall, with glass panels. The flume has a total length of about 29.5 m from the east end to the west wall which delineates the outlet wall, a cross section of 1.5 X 1.5 m, with a maximum still water depth of 1.2 m. The flume is serviced by high-capacity pumps (2 x 0.5 m3/s = 1.0 m3/s) that draw from a large (300 m3) water storage reservoir situated below the flume bed. The section where the wave maker will be installed has a strong, reinforced concrete wall on both sides. Refer to Figure 1: Multi-Hazards Simulator. For further information regarding the installation site and current infrastructures, please refer to Appendix L - Investigation and Recommendation Study. The new wave generator system must be manufactured and delivered as soon as possible. Therefore, the immediate planning for the wave generator system must be made in coordination with the users and the University of Ottawa Facilities team such that the construction works which is required for the installation to be also carried out to manage potential interfaces and dependencies immediately after contract awarding. Official bid documents must be obtained from www.merx.com and bid submissions must be done through the Merx platform. Question Acceptance Deadline: 2024/10/29 03:00:00 PM EDT
