All rights reserved. <br />Task 1 – Project Management and Administration <br />Engineer will support the Owner by managing the project to coordinate the bench <br />scale testing tasks, monitor and control the project budget and schedule, and keep <br />the Owner informed of project progress and issues necessary for success of the <br />project. Engineer will provide project supervision, direction, and coordination with <br />the Owner’s management and staff. Project administration and management also <br />includes budget and schedule control, client management support, document <br />control, coordination of activities, monthly invoicing and project close-out. <br />Engineer will maintain a change register of any scope changes affecting the project <br />budget or schedule and review it with the Owner on a monthly basis. Engineer shall <br />discuss and receive written approval for any scope changes from the Owner prior to <br />proceeding. <br />Task 2 – PFAS Bench Scale Testing <br />Engineer will conduct bench-scale testing to select the best-performing adsorptive <br />media for each WTP. <br />Engineer will conduct Rapid Small-Scale Column Tests (RSSCTs) at the <br />Engineer’s research facility in Kansas City, Missouri to assess performance of <br />alternative media products and validate design parameters. For each WTP, <br />Engineer will perform RSSCTs on water samples collected from the finished <br />water (HSPS discharge) using three (3) columns, including three (3) different <br />types of AIX resin, totaling six (6) columns between Pinhook and North WTPs. <br />Engineer will perform a literature search prior to testing to confirm optimal <br />products selected for bench-scale testing. Testing will evaluate the relative <br />performance of the finished water from Pinhook and North WTPs to simulate <br />installation of adsorbent contactors at the effluent of the high service pumps, prior <br />to final chemical feed points. Observation of contaminant breakthrough will be <br />used to characterize the performance of each media relative to each other. <br />RSSCTs will require collection and shipment of four (4) 55-gallon drums of water <br />(two from each facility). Engineer will ship drums with liners to the City and <br />coordinate sample pickup and shipping with a local shipping agency (shipping <br />costs included in the Proposed Fee). City staff will be responsible for collecting <br />and preparing water samples for shipment and dosing chlorine quenching agent in <br />the water prior to shipment. Engineer will arrange for liftgate services for the <br />delivery and pickup of the drums. <br />Engineer will prepare and submit a bench-scale test protocol to the City. Engineer <br />will participate in a review meeting with the City within two (2) weeks of <br />submitting the draft protocol. Attendees will include the Engineer project
