City of La Porte Fairmont Park Lift Station <br />Attachment A Scope and Budget of Engineering Services <br /> <br />information regarding force main discharge elevation (City records of manhole inspection reports, <br />confirmation by City crew, and/or available elevation information in models). <br /> <br />2. Geotechnical <br />A. Tasks: Define subsurface conditions and soil engineering properties. <br />B. Questions/Information: Primarily soil loads for new structure design, types of soils which affect <br />trench/excavation safety, and groundwater. Not likely to be required if site excavation is minimal and <br />limited to the line depths. <br />C. Alternate Source: Previous geotechnical reports for this site. <br /> <br />3. Electrical: <br />A. Tasks: It has been stated it is preferred to maintain the existing "pump horsepower" ratings in order <br />to re-use the primary feed and standby power. Given the existing pumps appear to be rated for 1100 <br />gpm, and the velocity in the existing 8-inch force main is near the maximum 6 fps maximum velocity, it is <br />unlikely there will be an increase in pump capacity without an increase in force main size. Additionally, <br />horsepower can be affected by deterioration of the existing force main. <br />B. Question/Information: This task will largely depend on the final pump capacity for design, and if <br />existing feed/generator requires significant re-location. <br />C. Alternate Source: Existing plans will require confirmation in the field. <br /> <br />3 of 3 <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />
