1 . Prepare detailed topographic mapping of the IRC Biosolids Dewatering Facility site, <br /> integrating the proposed facility with the Solid Waste Master Plan. <br /> 2 . Determine locations and elevations of existing structures (including finished floors) , <br /> roadways, visible utilities and storm drains, adjacent property lines, and horizontal and <br /> vertical control for construction . <br /> 3 . Provide survey information in digital format in AutoCAD, 2000 . <br /> Subtask 1 . 4 - Preliminary Design Report <br /> CDM will provide the following services related to the preparation of a PDR : <br /> 1 . Prepare a mass balance to determine necessary equipment sizes, specifically to design <br /> for the 20 year facility life cycle . <br /> 2. Prepare process design criteria based on projected quantities generated by IRC Utilities <br /> and the current and future projected grease and septage quantities . <br /> 3 . Establish floor plan, finished floor elevations, and space requirements for the sludge <br /> receiving station, the sludge storage, the sludge dewatering requirements, the <br /> dewatered sludge loading area, septage and grease storage and treatment facilities, and <br /> other required facilities . <br /> 4 . Prepare a preliminary site layout of equipment and structures for each individual unit <br /> process . <br /> 5 . Coordinate with IRC staff for existing utilities including water, sewer, electrical and <br /> control wiring locations and yard piping. Explore using Landfill gas as an alternate fuel <br /> supply for the facility . <br /> 6 . Based upon the geotechnical report, develop design criteria for building and tank <br /> foundations, select the structural system, and determine appropriate design codes and <br /> structural loads . <br /> 7. Develop a preliminary process instrumentation and control diagram (P&ID) with <br /> schematic to show recommended control and monitoring system configuration and <br /> single line electrical diagrams . <br /> 8 . Develop a preliminary schedule for new facility design and new facility construction . <br /> 9 . Develop preliminary opinion of probable capital construction cost. <br /> 10 . Identify necessary permits and anticipated permit conditions . <br /> 11 . Develop implementation schedule identifying major task milestone dates . <br /> 12 . Conduct a review workshop with IRC staff at the 75 percent PDR completion stage . IRC <br /> will invite potential vendors to review the preliminary design and request their input. <br /> A-3 mh2200.doc <br />
