Reference Number 0000271459 Pricing Lump sum Question Acceptance Deadline 2024/06/13 10:00:00 AM EDT Quinte Conservation is requesting a dam safety review be completed for the Bloomfield 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. Include a provisional price to 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. Prince Edward County (PEC) is planning trail improvements later in 2024 around the perimeter of the Bloomfield Mill Pond. The proposed works include the following in and around the dam spillway; pedestrian bridge, trails, sitting areas and plantings. The PRSA/PSP for this project will be completed shortly after the contract award and will include reviewing the proposed works against the current MNR Dam Safety Guidelines (2011). One site visit with the trail planning team should be completed to understand the scope of the trail project and to communicate any associated safety measures, modifications and/or considerations. Provide any recommendations or modifications to the proposed works and provide associated costs (if applicable). The review will be provided to PEC who may request further clarification or suggestions. 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 recommend rehabilitation methods, costs and timeframes. MNRF 2011 Technical Bulletins should be followed for all aspects of the project scope. Official bid documents must be obtained from www.merx.com and bid submissions must be done through the Merx platform.
