Field Exploration. ATL performed site reconnaissance. Project alignment will be accessible with our truck-mounted drill rig, and Peace officer and flag man with control signs and cones will be at site during drilling operation for work personnel safety. Based on the Boring Depth and Frequency Requirements provided, ATL proposes the following T:\Proposal\2021\GP21-0417 - Xxxxxxxxxx-Xxxx\GP2021-0417 Proposal.doc
Field Exploration. Site Access. The site access can be provided using a truck-mounted drilling rig along the major portion of alignment. Traffic control will be required. Due to presence of soft subgrade soils and potential access problems along a portion of the project alignment near FM 762 and at the proposed detention pond location, an ATV rig may have to be used to drill borings. Surveying. The client will establish and provide GET the boring coordinates and ground surface elevations. GET will mark the boring locations in the field so that the survey crew can locate them. Proposal No. P21-071-1 GEOTECH ENGINEERING AND TESTING Checking for Utilities. GET will call Texas 811-Call for the locations of utilities. GET will coordinate these activities. GET will not hire a contractor to conduct subsurface utility studies to find location of any and all utilities. This is not the scope of GET work. We recommend the scope of our work to include subsurface utility investigation at boring locations to assess those underground utilities are not hit during field exploration. Traffic Control. Traffic control will be required along the project alignment during our field exploration. The scope of our field work will require a lane closure during drilling and sampling and borehole grouting. Our traffic control will be subcontracted out. Drilling and Sampling. We will evaluate the soil stratigraphy and groundwater conditions for the proposed paving and storm sewer improvements by conducting fourteen (15) soil borings to a depth of 15-ft from existing grade. It should be noted that spacing between borings is about 500-ft. We will conduct two (2) soil borings near the proposed detention pond (optional) to a depth of 25-ft from existing grade. The Plan of Borings is shown on Plate 2. The borings schedule is as follows: Facility Borings Depth, ft Remark Paving and Underground Utilities B-11 through B-51 & B-6 through B-15
Field Exploration. ATL performed site reconnaissance. Project alignment will be accessible with our truck- mounted drill rig, and traffic officer and flag man with control signs and cones will be use during drilling operation for work personnel safety. Based on Boring Depth and Frequency requirements provided conduct geotechnical investigation involving six (6) at 15-ft deep soil borings for the road improvements. Soil samples will be obtained continuously to a depth of 15 ft. Standard Penetration Tests (SPT) will be performed in sands, if encountered, and clays will be sampled by Shelby tube. Shear strengths of the clays will be measured in the field with a hand penetrometer and correlations between this data and laboratory shear strength data will be made during analysis. Depth to ground water will be important for the design and construction of this project. For this reason, the borings will be drilled dry and the depth at which groundwater is encountered will be recorded. The boreholes will be grouted with cement-bentonite slurry after the completion of drilling and sampling.
Field Exploration. Based on the available project information, ATL proposes the following borings to investigate the subsurface soils and groundwater conditions along the site boring locations and are presented in Figures 1 & 2.

Shear strengths of the clays will be measured in the field with a hand penetrometer and correlations between this data and laboratory shear strength data will be made during analysis. Depth to groundwater will be important for the design and construction of this project. For this reason, the borings will be drilled dry and the depth at which groundwater is encountered will be recorded. The boreholes will be left open for 24 hours, and 24-hour water level will be recorded, and the boreholes will be grouted after the completion of drilling and sampling. two (2) 50-ft deep piezometers will be installed to monitor the 24-hr, 7- and 30-day ground water level. The piezometers will be pulled and plugged after the 30-day water level reading. Consolidated- undrained Triaxial Test (ASTM D 4767) 3-stage with 3 samples set, and soil dispersiveness tests (double hydrometer Test, Crumb Tests) are required at channel cross section.
Field Exploration. Site Access. The project alignment is along the existing 2-lane asphalt roadway. Therefore, site access can be provided, using a truck-mounted drilling rig. Traffic control will be required. Due to presence of soft subgrade soils and potential access problems, an ATV rig may have to be used for the boring near the proposed outfall (optional).
Field Exploration. Shall include site reconnaissance and borings.

Field Exploration. A. For the purposes of our geotechnical exploration, Xxxxxx proposes to drill a total of three (3) soil borings to depths of 10 feet or practical auger refusal, whichever occurs first.
Field Exploration. ATL assumes the existing project alignment will be accessible with our truck-mounted drill rig, and traffic control signs and cones will be use during drilling operation for work personnel safety. ATL assumes that the permission to access to the proposed boring locations along the project alignment will be provided at ATL at no cost. The field investigation will be performed in accordance with Standard Practice for Soil Investigation and Sampling by Xxxxx Xxxxxxx [ASTM D 1452].
