For the purpose of the assessment, the Consultant will review 2 aeration and 2 clarifier basins (one from each phase of construction). The results will be extrapolated to the other basins. Only one aeration basin and one clarifier basin will be emptied at one time (i.e. 2 deployments would be needed in order to complete the assessment).
PHASE I – Project Management
1. The consultant will m eet with City to review project objectives and history and confirm the project scope and budget.
2. The consultant will conduct bi-weekly design calls with all stakeholders to update the progress of the design and receive input (4 calls expected).

The item also includes additional services beyond the defined deliverables throughout the project. These services include items such as answering questions, e-mails, resolving billing questions/providing additional details etc.
PHASE II – Field Assessment
1. The consultant will conduct a visual assessment of the basin structure and adjacent structures to document the current physical condition of structural and waterproofing elements. Field work will be conducted in 2 phases with each phase requiring 2 days in the field:
a) Typical concrete elements including floors, columns, beams, walls and other structural elements. The visual review will document noticeable distress such as cracks, leaks, spalls, joint deterioration and other similar adverse conditions. b) Other elements that are noted during the field evaluation.
The field evaluation will include field-testing, material testing and non-destructive evaluation of select concrete members. The field testing and visual review will be used to develop viable repair approaches and alternatives by the Consultant. The following field tests are anticipated for the testing program:
c) Acoustic sounding of select elements to identify delaminated areas in columns, beams and walls.
d) GPR survey of reinforced concrete floor slabs at selected locations in each structure to confirm the typical depth of reinforcement and concrete cover. e) Half-cell testing to determine the corrosion potential of the concrete in the walls area that show signs of corrosion related damage and cracking (3 locations in each deployment).
Half Cell Testing provides additional data that will help with the repair recommendations. f) Cores will be extracted from the walls at select locations to understand the condition and composition of the existing concrete (planned to extract 7-8 cores for each phase). These will be sent to an independent laboratory for testing. The following tests are anticipated and included in the laboratory costs.
I. Sulphate tests 2 cores – 4 depths (0”, 1.5”, 3”, 4.5”,6”) Total 8 tests II. pH testing of 4 cores - 4 depths (0”, 1.5”, 3”, 4.5”,6”) Total 16 tests III. Petrographic Testing of Cores 2-3 cores
IV. Compressive Strength Testing 6 cores
2. The consultant will notify the City of items in need of immediate repairs required for the continued safe use of the structure(s), if there is any.
3. The Consultant will c ompile and analyze field evaluation data and finalize the quantities of 6 wo
rk.
4. The Consultant will generate repair options, recommendations, and opinions of probabl e co
sts.
5. Based on the condition assessment, the Consultant will prepare a report that contains an executive summary, observations, including photographs depicting of the areas observed duri ng the r
eview, results of materials testing and a discussion of the long-term implications, discussion of observed conditions and conceptual repair options, and recommendations for repairs.
