484-2023 - Consulting Service for St. Norbert Separated Sewer District Preliminary Design

Full Title: Professional Consulting Services for the St. Norbert Separated Sewer District Preliminary Design

D7.          SCOPE OF SERVICES

D7.1        General Project Scope Summary
D7.1.1             Based on the future growth projections for the St. Norbert and Grandmont 
Separated Sewer Districts, confirm infrastructure upgrades to the sanitary sewer system for the St. 
Norbert Lift Station. While ensuring it maintains or improves the level of service for the St. 
Norbert Separated Sewer District.
(a)   Data should be collected and assessed to ensure sufficient information is available to 
achieve the Preliminary Design requirements.
(b)   The model should be updated and calibrated as required to make it 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 flows as a result of an upgrade to the St. Norbert Lift Station, 
the downstream local sewer network needs to be assessed and where detriment is predicted; solutions 
to address the detriment needs to be developed.
(i)     The assessment requires a review of the local sewer system to the Interceptor
Avenue/Kirkbridge Drive and Pembina Highway.
(ii)     It is assumed that downstream conveyance capacity improvements will be required.
(f)    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 under both current and future growth conditions by 
undertaking detriment assessment. An example template of the detriment assessment is provided in 
Appendix F 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.
(g)   Cost estimation should be developed and contract phasing should be proposed.
(h)   Review the overall hydraulic impact as a result of the proposed solution.

D7.2        The Services required under this Contract shall consist of the following Tasks and as 
outlined in D8 to D12 and D14 in accordance with the following:
(a)   Project Management (D8);
(b)   Hydraulic Modeling (D9);
(c)    Geotechnical Investigations (D10);
(d)   Options Analysis (D11);
(e)   Preliminary Design Report (D12); and
(f)    Additional Work Allowance (D14).

D7.3        The optional task under this Contract as outlined in D13 in accordance with the 
following:
(a)   Optional Design: Local Infrastructure Upgrades Preliminary Design (D13).

D7.4        The funds available for this Contract are $700,000.
(a)   The funds available in D7.4 only pertain to the Services required in D7.2. If D7.3 is within
