• The survey will include locations of physical features that may be affected by <br />construction, including sidewalks (type), driveways (type), roadways, railroads, <br />fences (type), walls, signs, mail boxes, planters, sheds, rock outcroppings, <br />manholes, cleanouts, meter boxes, valve boxes, curbs (back of curb and lip), <br />storm inlets, junction boxes, structures, power poles, guy wires, etc. <br />• Rim and invert information will be provided for all accessible manholes. <br />• Depth to valve operator will be provided for all accessible water valves. <br />• Surveyed features located horizontally relative to NAD 83 State plane <br />coordinates. <br />• Horizontal control will be carried to second order accuracy. <br />• Tree survey of trees 9" or larger. <br />Geotechnical investigation for reclaimed water pipeline design. <br />o Subsurface investigation consisting of <br />❖ Preliminary investigation. Drilling four (4) 20 -ft deep pipeline borings, <br />spaced as requested nominally about 1,000 ft apart, for preliminary <br />information and design; <br />❖ Drilling four (4) 20 -ft deep supplemental pipeline borings at requested <br />locations for final design. <br />❖ Coring the bedrock continuously at the boring locations with NQ size core <br />barrel; <br />❖ Logging the borings as they are drilled; <br />•'• Storing core in core boxes; <br />❖ Bailing open boreholes to obtain a 24 -hour water level reading; <br />❖ Backfilling open boreholes with bentonite pellets and/or cement/bentonite <br />mixture, and road patching materials; and <br />❖ Installing one (1) piezometer at IH -35. <br />• Laboratory services that include: <br />❖ Moisture contents and unit dry weight determinations, <br />❖ Sieve analyses (No. 4, 40 and 200), <br />❖ Liquid and Plastic limit determinations, and <br />❖ Unconfined Compression Tests. <br />• Geotechnical Data Report (GDR) that compiles all field and laboratory testing <br />into a report complete with boring logs, and laboratory and test results. <br />• Geotechnical Design Memorandum (GDM) for reclaimed water storage reservoir <br />and Open Cut Sections that addresses stable slopes for construction, groundwater <br />conditions at the time of construction and effects on construction. <br />16 <br />
