The Proponent is encouraged to review the major work components and provide additional information on how the work components could be altered, updated, or sequenced appropriately as part of their Proposal submission.
D7.2 Review all applicable information, data, surveys, reports and existing drawings related to the Project including, but not limited to the information contained in this RFP.
D7.3 The Services required under this Contract shall consist the following:
(a)Phase I: Complete an Environmental Site Assessment (ESA)/Existing InfrastructureAssessment (referred to below as ‘Phase I Report’) of the Sludge Drying Beds Site:
(i)The entirety of this phase will be paid out as a Fixed Price item in accordance withSection B9.
(ii) The Proponent will request and review all pertinent background reports, operating data, and any other data the Consultant feels pertinent in the background evaluation.
(iii) The Proponent will submit any specific questions on the Sludge Drying Beds history/use to the City Project Manger to forward on to appropriate staff during this phase.
(iv) The majority of the work within this phase is tied to the submission of Phase I Report, which will include the following at minimum:
(i) The ESA aspects of this report can be aligned with the requirements of CSA-Z768-01 (R2022) for completion of a Phase I Environmental Site Assessment, but does not necessarily need to comply with all requirements.
The intention to align with CSA-Z768-01 (R2022) is to provide a template for the format for the report deliverables.
(ii) The ESA aspects of this Phase may also be aligned with the requirements of Manitoba Environment & Climate’s Guideline for Environmental Site Assessments in Manitoba.
(iii) The following items identified within CSA-Z768-01 (R2022) are specifically clarified related to this work:
Interviews can occur via email inquiries, submitted to the City Project Manager as stated in D7.1(a)(iii) above. They are not required to be in-person interviews.
Interviews with staff can occur to confirm the status of specific infrastructure believed to be decommissioning or still in operation. Interviews with staff can also gather necessary background on the current operational issues/concerns in the use of existing infrastructure.
The Proponent should consider the site visit requirements for the purposes of reviewing the entire site visually and taking a suitable number of photographs to demonstrate the current condition of the lands. This will be as part of completing the Site Visit component of the Phase I Report.
As part of the Records Review component of the study, detailed review of existing municipal servicing drawings should be completed. This exercise should result in a detailed Infrastructure Inventory of all existing infrastructure believed to be currently in operation.
The Records Review should particularly focus on confirming the extent of decommissioning works completed through the 1990s as part of decommissioning the drying cells, and construction of the asphalt drying pad.
(iv) The following requirements will augment the typical requirements of a Phase I ESA in accordance with CSA-Z768-01 (R2022), in order to document the Existing Infrastructure:
Cursory statements as to the expected condition of the existing infrastructure is also be contained in the report. Expected condition is to be assessed based on the records review, interviews with staff, and basic information gathered from the site visit.
All infrastructure no longer in operation, but unknown if fully decommissioned to be documented in this report within the Infrastructure Inventory.
All infrastructure no longer in operation, but known to be decommissioned based on past project work to be documented in this report within the Infrastructure Inventory.
All infrastructure supporting the current site operation, including the decant pump station and the 5.5 km forcemain extents (3.2km length prior to tying into the local WWS system, and the remaining 2.3km segment disconnected but not removed) is to be included within the Infrastructure Inventory under consideration.
(b) Phase II: Complete Sampling/Infrastructure Assessment Plan

(ii) It is recommended the Proponent notify the City Project Manager when they intend to begin work in this Phase within the Proposal, should it be desired to occur concurrently with the Phase I report submission.
(iv) The Sampling Plan component of this proposal can be drafted in accordance with CSA-Z769-00 (R2023) acting as a template. This will establish all intrusive investigations proposed to determine soil and ground water conditions with the objective of determining the extent of impacts, in any, to allow for the preparation of remediation options in accordance with Phase IV of the Work.
(v) The extent of samples completed, along with the overall number of samples proposed to be collected and tested, is to be based on the specific environmental risks identified in the ESA, along with the budget available with the Additional Work Allowance.
(vi) Sampling shall be completed against appropriate environmental quality guidelines or regulatory requirements, as applicable and in the professional judgement of the Proponent.

(ii) Specific environmental quality guidelines/requirements assumed to be applied samples collected shall be documented within the Sample Plan of this proposal.
(vii) The Infrastructure Assessment component should present a sequence of tasks to review/confirm the condition of existing infrastructure identified in the infrastructure inventory.
(viii) The Infrastructure Assessment component should also present any tasks required to confirm existence or existing infrastructure, or status of decommissioning of existing infrastructure as required.
(ix) The scope of condition assessment tasks is to be determined by the Consultant based on the risks/condition of specific infrastructure, the extent of existing infrastructure to be assessed, along with the budget available within the Additional Work Allowance.
(x) The Sampling/Infrastructure Assessment Plan shall include an updated Safe Work Plan the Consultant specific for the site sample and infrastructure assessment work.
(xi) The estimated costs for the tasks expected in the Sampling/Condition Assessment Plan is to be submitted within the plan, utilizing Form P: Person Hours utilizing Key Personnel hourly estimates, along with Subconsultant prices.
(c) Phase III: Complete soil testing, groundwater monitoring, or laboratory testing of samples collected to confirm specific sources of contamination, if required. Site investigations to further assess the condition of existing infrastructure on site, or to assess the status infrastructure believed to be decommissioned, are also to be completed in this phase.
(i) The entirety of this phase will be approved utilizing funds from the Additional Work Allowance.
(ii) The Sampling/Infrastructure Assessment Plan is expected to be complete before this Phase can begin, as this deliverable will form the proposal for approval to utilize the
Additional Work Allowance. Under extenuating circumstances such as seasonal impacts on site investigation activities, portions of this phase may be initiated or completed prior to the completion of the Sampling/Infrastructure Plan.
(iii) The initiation of this work however can occur concurrently with the remaining tasks related to the development of the Phase I report, under the condition where the Sampling/Infrastructure Assessment Plan is approved prior to the completion of the Phase I report.
