AI summary The text provides a summary of related Cl's over a two-year period, indicating no other projects were undertaken between 2008 and 2012. It includes a CI number, project name, parent CI number, cost centre, and budget version details.
Person Responsible: Why do this project? A flood study was completed to identify the required spillway capacity for the structures on the Tusket Hydro System in accordance with the CDA guidelines. A dam safety review was also completed in...
AI summary A flood study and dam safety review identified that the Tusket Hydro System's Carlton Lake has insufficient freeboard, unstable spillway and stoplog structures, and a non-compliant fish ladder, necessitating upgrades to meet safety and regulatory standards.
Why do this project this way? The dams and/or spillways need to be refurbished to meet the Canadian Dam Safety guidelines for freeboard and stability. Therefore it is necessary to increase the length and stability of the spillway structure...
AI summary The Carlton Lake Dam refurbishment project is necessary to meet Canadian Dam Safety guidelines by increasing spillway length and stability, raising the dam crest, and ensuring structural integrity. The project is identified under CI Number 28726 and Cost Centre 408-Tusket Hydro.
1.0 PROJECT DESCRIPTION In January 2006, AMEC completed a Dam Safety Review (DSR) of the Carleton Dam. At the time, it was recommended that the dam be upgraded in order to meet the minimum criteria of the 1999 Canadian Dam Association (CDA...
AI summary The Carleton Dam requires upgrades to meet safety guidelines, including raising embankments, installing concrete overlays, and replacing timber structures. AMEC proposes conceptual design and cost estimates, with NSPI responsible for fishway design. Discussions address construction methods like cofferdamming.
2.1 General NSPI's request for proposal comprised two phases: - Phase 1 Conceptual design and capital cost estimate. - Phase 2 Detailed design and construction support. AMEC's proposed scope of work will also comprise of two phases. The pr...
AI summary NSPI's request for proposal includes two phases: conceptual design and capital cost estimation (Phase 1), and detailed design and construction support (Phase 2). AMEC's scope involves a one-day workshop with NSP personnel to discuss remedial options and phased design development, including feasibility studies, detailed designs, and construction support.
2.2 Geotechnical Investigations and Surveying In order to proceed with the designs, it is recommended that additional survey information be gathered at the site. A geotechnical investigation including some laboratory testing is also recomm...
AI summary The document recommends conducting geotechnical investigations and surveying in 2008 to gather site data and confirm soil properties. Results may influence design analyses, with costs for potential re-analyses provided separately.
Work Included - Phase 1 2.3 3. Confirm AMEC will undertake the following for the Phase 1 conceptual design: Review documents and conceptual design alternatives to support the selection of 1. the preferred option; 2. Undertake a one-day wor...
AI summary AMEC will conduct a conceptual design for Phase 1, including reviewing alternatives, holding a workshop with NSPI, designing new infrastructure per dam safety guidelines, preparing capital cost estimates (25-35% accuracy), and managing the project efficiently.
2.4 Work Included - Phase 2A AMEC will undertake the following for the Phase 2A feasibility design: Undertake a geotechnical investigation by drilling three 30 ft deep boreholes at the main structure and back spillway to confirm strength p...
AI summary AMEC will conduct geotechnical investigations, site surveying, stability analysis, and feasibility design for Carleton Dam's Phase 2A, including revised capital cost estimates and project management. The work focuses on foundation properties, embankment design, and infrastructure upgrades.
2.5 Work Included - Phase 2B AMEC will undertake the following for the Phase 2B detailed design: Complete the detailed design of the new embankment and wingwalls, spillway, rock anchors, embankment raise and back spillway replacement emban...
AI summary AMEC is responsible for Phase 2B detailed design work, including new embankments, spillways, rock anchors, and IFC drawings. The scope involves structural engineering tasks for infrastructure components.
2.7 Work Not Included - Phase 1 and Phase 2 The following items of work are not included in this estimate but can be provided as extra work items if required: - 1. Confirmation of land ownership; - 2. Confirmation of flowage rights; - 3. H...
AI summary The document outlines work items excluded from the initial estimate for the Carleton Dam project, including land ownership confirmation, permit applications, archaeology studies, and Freeboard analysis reviews. These may be required during design phases or later, with costs to be determined upon further details.
6.0 SCHEDULE AMEC will undertake the work outlined immediately upon award of contract. 111$ understood that, depending on fundIng, the surveying and geotechnlcallnvestlgation would be carrIed out in 2008 wIth the remainder to be completed...
AI summary AMEC plans to conduct surveying and geotechnical investigations in 2008, with remaining work completed in 2009. The recommendation prioritizes these initial tasks due to their direct impact on subsequent project phases.
