14) Prepare an animation of the Project with three design/aesthetic options: Standard <br />TxDOT Bridge and two other options that the Engineer will develop in coordination <br />with City staff. The animation will include: <br />a) A model of existing conditions; <br />b) An aerial visual impact study; and <br />c) A fly through 3- dimensional model of the Project for each option with pavement <br />markings and blended into existing aerials; and <br />1.2.2 Geotechnical Investigation and Report. <br />1) Field Program: <br />a) Supervise drilling activities and collect test samples utilizing either thin - walled <br />tube samplers (Shelby tubes) or the standard penetration test. In accordance with <br />TxDOT procedures, perform a TxDOT Cone Penetrometer test at approximately <br />five -foot depth intervals in the borings. When rock is encountered, the Engineer <br />will advance the borings using Nx coring equipment. Once the Engineer has <br />collected and classified the samples in the field, the Engineer will properly <br />prepare and place the samples in appropriate sample containers for transport to the <br />Engineer's laboratory. <br />b) Upon completion of the borings, backfill the boreholes using excess soil cuttings <br />and /or bentonite chips, patched with quickrete or cold -patch asphalt. The <br />Engineer will approximate the borings using field personnel based on preliminary <br />plans and available site features. The Engineer will perform a majority of the <br />planned borings within existing roadways and these borings will require <br />maintenance of the affected traffic area. <br />c) As a precaution, notify the Texas One -Call system to locate underground utilities <br />within public right -of -ways and easements at the Project site. Borings will be <br />performed by the Engineer as follows: <br />Location <br />Loop 82 Soil Survey <br />Retaining Wall Foundation <br />Investigation <br />Bridge Foundation <br />Investigation <br />No. of Borings Boring Depths Total Drilling Footage <br />14 <br />10 <br />M <br />10 feet 140 LF <br />8 @15 feet <br />180 LF <br />2 @30 feet <br />60 feet 360 LF <br />2) Laboratory Testing: Review the sample classifications and assign a laboratory- testing <br />program, which will be specific to the Project requirements, the subsurface <br />conditions, and in accordance with TxDOT standards.
