Stantec Consulting Services Inc. 13 of 16 <br />TO1 – Randolph-Sampson RTB PER <br />structural, architectural, building mechanical, electrical, and instrumentation and control (I&C) design <br />criteria. <br />Subtask 4.5- RTB Ventilation and Odor Control <br />STANTEC will evaluate up to three (3) alternatives to provide ventilation and odor control for the RTB. <br />Design criteria will be defined for the recommended approach. <br />Subtask 4.6- Dewatering Pump Station <br />STANTEC will evaluate up to three (3) options for the dewatering pump station required for the RTB (wet <br />pit submersible, dry pit submersible, alternative configurations) <br />STANTEC will obtain data from pump manufacturers for discussions with CITY staff related to pump <br />capacity, operating range, and operation and maintenance considerations. STANTEC will evaluate <br />constant speed pumps vs. variable frequency drive (VFD). <br />STANTEC will develop a conceptual layout and design criteria for the electrical, instrumentation and <br />control equipment associated with the required pumping system. STANTEC will coordinate with the CITY <br />operation staff to review existing CITY standards, existing installed systems, and options for integration <br />of monitoring and control with the CITY’s SCADA system. <br />Subtask 4.7- RTB Layout and Construction Method <br />Based on site constraints and hydraulic and process design needs, STANTEC will develop a conceptual <br />layout of the RTB including depth, shape, dimensions, and interior configuration. <br />STANTEC will evaluate three (3) construction methods for the RTB: <br />• Conventional cast-in-place concrete structure. <br />• Hybrid cast-in-place concrete structure which involves installing a permanent diaphragm wall or <br />contiguous secant-pile wall as an excavation support system and groundwater cutoff; this wall <br />would then be integrated into the tank as part of its foundation and exterior wall. <br />• Prestressed concrete Water Tank such as AWWA D115 Tendon-Prestressed Concrete Tank such <br />as the Dutchland® Tank. <br />STANTEC will review the preliminary geotechnical data obtained from Subtask 2.4 and develop RTB <br />structural design criteria. Requirements for additional geotechnical investigations to be performed <br />under separate scope as part of detailed design will be identified. <br />Subtask 4.8- Site Civil, Utilities and Landscape Design <br />Using the conceptual layout developed in Subtask 4.7, STANTEC will define site design criteria for <br />landscaping, grading, stormwater management, and utilities (water, sewer, force main, power, duct <br />bank, fiber optic) to meet the CITY standards and anticipated stakeholder interest in modifications or <br />improvements to the existing recreational space adjacent to the project site. The design criteria will be <br />used to develop conceptual site civil drawings for the project site including a conceptual grading plan, a <br />conceptual plan for utilities and street improvements, and a conceptual recreation and landscaping plan.
