The vendor is required to provide the assessment will encompass riparian health and aquatic assessments, capacity analysis, sediment quality and quantity, physical condition assessments, invasive aquatic fish and vegetation assessment, provide case study including recommendation for best practice in establishing a long-term maintenance for all stormwater management facilities (SWMF) facilities.
1. Data collection
• Collect, assemble, and review all current documents and standards relevant to the project including but not limited to: as-builts, utility base plans, site plans, design drawings, GIS lidar data, etc.
2. Project communication and management plan
• Kickoff workshop to review condition assessment criteria, and project expectations
• Provide monthly progress reports that summarize information documented in daily logs including any impacts to schedule, and any direction provided to the issues.
• Each meeting should include written documentation that includes progress since last meeting, work proposed for the following period, safety records, contemplated change orders, and updated schedule including lost days.
• A record of resident interactions with any site personnel should be kept by the consultant with a record of when contact was made, issue, who is responsible to respond and the date and explanation of resolution.
• Provide a copy to the city on a biweekly or monthly basis.
• The consultant shall coordinate any utilities locates as required to undertake all works associated with the inspections and investigations.
3. Investigation and inspection
• Assessment and analysis of attributing upstream drainage risk, impacts, or other relevant factors that influence the functional capacity and capabilities of each SWMF
• Carry out condition assessment of all the SWMF in the city including the development of a 10-year capital plan and cost estimate based on the findings.
• The six types of inspections to be untaken are as follows:
o Physical condition
o Sediment quantity
o Sediment quality
o Riparian and aquatic vegetation health
o Slope stability
o Fish inventory
• Assess the health of the riparian areas, including the aquatic zones within each SWMF
• Investigate the condition of SWMF embankments, berms pathways and inlet structures to identify potential signs of soil-related failures and conditions.
• Review of current provincial legislation regarding environmental protection and safety.
• A eDNA survey of the facilities to determine the presence and absence of multiple invasive species, including mussels, fish, plants.
• Investigation and inspections are to be planned to minimize the impact to the residents, businesses, and transit operations or public operations maintenance activities where possible for areas affected by the work.
• Provide a tentative accommodation plan where possible including design of any bypass routes.
• Provide site photos and photos of investigation and inspection activities.
• Copies of photos to be provided as part of the reports.
• Document all investigations and inspection’s procedures and results and form part of the final report.
4. Final assessment report and recommendation
• Assessment of the current conditions of the SWMFS.
• Recommendation of corrective actions and/or improvements of the SWMFS.
• Recommend mitigation and remedial measures to ensure riparian health, vegetation condition, and productive capacity of the SWMFS are maintained.
• Based on the evaluated basin and sediment analysis recommend disposal plan and potential for beneficial reuse options.
• Coordinate with city on implementation of city standards for SWMF’S.
• Provide short-term and long-term maintenance plan for each SWMF.
• Provide assessment report review and workshop at 60% and 90% allowing 2 weeks at each stage for the project team to review.
• 60% project stage means that report within the assessment package is 60% complete, and the 90% stage means that report within the assessment package is 90% complete.
