NAD 83 Texas State Plane Coordinates, Central Zone 4203, US Survey feet. Vertical Datum will <br />be relative as to that established for the above projects and reconciled to the COSM Survey Control <br />System. <br />3. Surveyor will set additional horizontal and vertical control as need for project (not to exceed 4 <br />control points). <br />4. Surveyor will prepare a topographic survey to include spot elevations along the project route, back <br />of curbs, driveways, visible utilities, drainage structures, centerline of roads, trees 8" and up, grade <br />breaks, flowlines, manhole inverts, and any other pertinent data to provide a F contour interval <br />DTM. <br />5. Surveyor will include sufficient boundary survey to prepare 3 permanent easements along the <br />project. It is assumed that a Temporary Construction Easement will be required and will run <br />parallel and coincident with the proposed permanent easement. <br />6. Surveyor will locate up to 6 geotechnical bore holes within the project limits (it is assumed this will <br />be a separate trip). <br />7. Deliverables will be a Microstation file with breaklines with F contour intervals, an ASCII file of <br />all survey points, signed and sealed exhibits with metes and bounds for the proposed permanent <br />easements and temporary construction easements. <br />8. Surveyor will prepare easements needed to cross LCRA existing easements. Surveyor will <br />coordinate with LCRA and prepare the exhibit and metes and bounds. <br />C. GEOTECHNICAL INVESTIGATIONS <br />Perform five (5) borings to a depth of about twenty (20) feet. The borings will be used to <br />investigate subsurface stratigraphy and to obtain samples for laboratory testing. Samples will be <br />taken using conventional split- spoon/Shelby -tube sampling techniques. Borings will be located in <br />the field utilizing a recreation grade hand -held GPS device and/or tape and right angle <br />measurements from existing benchmarks. <br />2. Upon completion of the subsurface exploration, a laboratory testing program will be designed to <br />define the strength and classification characteristics of the subsurface soils. The testing program <br />may include moisture content tests, Atterberg Limits (plasticity tests), unconfined compression (of <br />the soil/rock samples), corrosivity testing, and grain size analyses; however, the type and number of <br />tests will be based on subsurface conditions encountered in the field. <br />3. The Geotechnical Engineer will coordinate with locator service to determine existing utility <br />locations. <br />4. The results of the field and laboratory phases of the study will be reviewed by our staff of engineers <br />and geologists. The results of our review, together with the supporting field and laboratory data, will <br />be presented in a written, engineering report. Included therein will be recommendations concerning <br />the design and construction of the water transmission line. The Geotechnical Engineering Report <br />will include the following information and recommendations, if applicable: <br />(a) A summary of the field and laboratory sampling and testing program, <br />(b) Boring logs and laboratory testing results; <br />(c) A review of general site conditions including descriptions of the site, the subsurface <br />stratigraphy, groundwater conditions, and the presence and condition of fill materials, if <br />encountered. <br />(d) Design considerations and recommendations, including: <br />(i) settlement estimations, where applicable; <br />(ii) expansive, soil- related movements using an empirical method for predicting Potential <br />Vertical Rise (PVR) developed by the Texas Department of Transportation; <br />(iii) methods for reducing expansive, soil - related movements; <br />(iv) allowable footing bearing capacities; <br />11/26/2013 <br />7 of 8 <br />
