REV: 11-07-23 SK <br />Consultant will prepare a memorandum (1-2 pages) documenting all <br />findings from the H&H analysis, including how the proposed pump station <br />improvements impact other improvements identified by the Master Plan. The <br />memorandum will include recommendations for additional pumping capacity, <br />storage, or pipe upgrades in proximity to the Price Tract Pump Station. The City <br />will issue comments on the draft memorandum, and Consultant will revise the <br />memo based on City comments and issue a revised memorandum. <br />Subtask 3.3 – Physical Modeling <br />Consultant’s subconsultant, Clemson Engineering Hydraulics, Inc. (CEH), <br />will prepare a physical model of the Price Tract Storm Drain Pump Station in <br />compliance with ANSI-HI 9.8 Hydraulic Institute Intake Design (2018) <br />standards 9.8 and 9.6.6 to evaluate the intake geometry and approach <br />hydraulics for the geometry and approach hydraulics for the pumps. The model <br />testing will be carried out in four phases. The actual test conditions will be <br />determined with additional input from the pump manufacturer, design engineer, <br />and City. CEH will prepare a project report containing methodology, <br />procedures, conclusions, and recommendations, as well as all data and <br />documentation acquired during the testing for each of the intakes. A draft report <br />will be made available at the witness test. Raw video footage of the testing will <br />be provided in DVD format. Each phase is described in the table below: <br /> <br />Phase Description <br />Baseline tests Baseline tests will be conducted with the <br />preliminary intake design development <br />under task 4. It is anticipated that 8 <br />baseline tests will be conducted, and the <br />data mentioned in the instrumentation <br />and data collection section of this <br />proposal will be collected during each <br />test. The worst-case conditions will be <br />determined during this phase of testing. <br />These tests will be used to determine the <br />nature and severity of hydraulic <br />phenomena occurring within the pump <br />intake structure. <br />Modification Tests Modification tests will be conducted and <br />modifications will be performed to bring <br />the pump intake within the performance <br />criteria. All proposed modifications <br />would be presented to City for approval. <br />Approximately 2 weeks have been <br />allocated to modification testing. <br />ATTY/AGR.2023.241/BKF Engineers (Price Tract Pump Station Design) (Page 17 of 54)
