Reference Number 0000271457 Question Acceptance Deadline 2024/06/13 10:00:00 AM EDT Pricing Lump sum The dam is located in Bloomfield, Prince Edward County, Ontario directly south of County Road 17 on the Black River. The drainage basin is 47.3km². The function of the dam is primarily for water supply and limited recreation. The dam is a concrete gravity dam that is approximately 40m long and 4.5m high. It is not operable. The location of the dam is downstream of the local swimming hole. As a result the dam may be accessed by the public as observed by graffiti issues, and garbage collection. Debris also accumulates at the bridge piers upstream and at the dam. Given the close location to County Road 17 bridge it can be difficult to determine the extents of the Quinte Conservation property and that of the municipality. Quinte Conservation will determine the exact dam limits to help with this issue. Quinte Conservation is requesting a dam safety review be completed for the Milford Dam. The review will be completed in accordance with the Dam Safety Reviews Best Management Practices (OMNR, 2011). It is anticipated that the work will include all the components of a dam safety review. Flood frequency analysis, regional frequency analysis, hydrologic modelling, flood routing and hydraulic analyses shall be in accordance with the Technical Guide - River and Stream Systems: Flooding Hazard Limits, (OMNR, 2002). Given the previous classification of the dam a dam break analysis is warranted and is to be completed as part of this study. Undertake an evidence based or conservative stability analysis of the structure to determine if dam safety criteria are satisfied. A seismicity assessment should also be included. If the structure does not meet stability requirements using conservative assumptions, concrete and geotechnical testing should be completed to confirm condition and material properties. A $15,000 cash allowance for this item is to be included for destructive and non-destructive testing. Create AutoCAD drawings complete with any revised elevations (obtained by surveying the concrete and embankment structure), cracks, delamination's, bulges, corroded metal, and all other applicable inspections notes. A Public Safety Assessment (PSA) is to be completed to identify potential public safety hazards. The PSA is to be completed in accordance with the Public Safety Around Dams Best Management Practices (OMNR, 2011). A recommendation should be made as to whether a Public Safety Plan should be completed. Provide a provisional price to complete a Public Safety Plan. Recommend actions, surveillance, monitoring, and maintenance activities including a timeline for completion and estimated budget. The budget items should come with a Class D breakdown. Provide the expectant lifespan of the structure with and without the recommended major modifications. Develop a seepage monitoring plan for Quinte Conservation to assess the seepage over time. Identify any imminent or future risks attributed to the seepage and possible rehabilitation methods, costs and timeframes. MNRF 2011 Technical Bulletins should be followed for all aspects of the project scope. Location: North of Black River, South Marysburgh Ward, Prince Edward County.
