Reference Number 0000260280 To develop a hydraulically feasible and buildable solutions to eliminate CSOs for the 1992 Representative Year Event and ensure sewer assets meet current level of service in the Cockburn CSD. (a) Data should be collected and assessed to ensure sufficient information is available to achieve the Preliminary Design requirements. (b) The model should be considered fit for purpose by the Consultant to assess the district needs and develop and test hydraulically feasible solutions in combination with other design tools as necessary. (c) Design criteria for assessing existing sewer asset performance and for sizing potential solutions with sizing process and documentation should be agreed with the City and documented. (d) The study area sewer infrastructure needs against levels of service and design criteria should be assessed and documented including wastewater capacity. (e) Where increasing wastewater pass forward flows the down sewer network needs to be assessed and where detriment is predicted solutions to address the detriment need to be developed. (i) It is to be assumed that downstream conveyance capacity improvements will be required. (ii) The construction phasing of the downstream capacity improvements should be developed along with any constraints to other sewer infrastructure investment projects like the Baltimore and Mager CSD mitigation projects. (iii) Any proposed increase in lift station capacity will be incorporated into the Lift Station Upgrading Program. (f) RTC and GI opportunities shall be explored and solutions developed where appropriate. (g) Review the proposed solution in the conceptual district plans and determine if the solutions may be carried forward or discarded if no longer viable based on improved information. (h) The developed solution shall meet the following requirements: (i) Meet the Design Standards specified in D6.4; (ii) Be buildable with location plans, general arrangements considering utilities, ground conditions, land ownership and health and safety; (iii) Pass the Level of Services checks by undertaking detriment assessment. An example template of the detriment assessment is provided in Appendix I City of Winnipeg Modeling Guidelines. Alternative design tool may be used to validate the Level of Service with the Consulting Contract Administrator approval; and (iv) Meet the level of service for a minimum design horizon of 35 years. (i) Cost estimation should be developed and contract phasing should be proposed. (j) The estimated CSO volume reduction should be provided on a construction contract by contract basis. (k) Review the overall hydraulic impact of the City as a result of the proposed solution, this includes the review of the impact on the districts hydraulically connected to the Cockburn East area. (l) Review the hydraulic and the cost estimates impact for changes to the proposed solution to accommodate additional flows discharged from other developments. The major components of the Work include the following: (a) Project Management (D7.6); (b) Data Collection and Assessment (D7.7); (c) Hydraulic Modeling and Assessment (D7.8); (d) Flow Monitoring and Management (D7.9); (e) Geotechnical Investigations (D7.10); (f) Design Criteria (D7.11); (g) Needs Assessment (D7.12); (h) Solution Development (D7.13); (i) Preliminary Design Report (D7.14); (j) Heritage Resources (D7.15); (k) Risks and Opportunities Identification (D7.16); (l) Stakeholder Engagement (D7.17); (m) Drawing Development (D7.18); (n) Cost Estimation (D7.19); and (o) Additional Work Allowance (D7.20). This Scope of Services item shall include all Project Management activities required to carry out each of the phases of work to achieve the deliverable requirements. Work under this task will include but not limited to the following: Official bid documents must be obtained from www.merx.com and bid submissions must be done through the Merx platform.
