ATI Geologica completed four Cone Penetration Tests to delineate soil stratigraphy and determine engineering parameters for a proposed Pinellas County Police Training Site using our New Track Mounted

TMG CPT-223 rig.

Below are the photos taken at various stages of the testing process, from setting-up the anchors, activating the data gathering electronic piezocone manufactured by VERTEK and pushing the CPT Cone at a rate of approximately 2 cm/s. At this project site ATI Geologica was evaluating conditions to depths of 25 to 30 ft.

 Our TMG CPT-223 features unique folding anchoring mast systems, allowing increased maneuverability in tight spots. The rig features dedicated anchoring drive heads, and a dual-hydraulic cylinder mast with a 20-ton pushing capacity. Folding anchors allow the rig to maneuver through 3.5 ft gaps.

Mr. Peter Christensen manages and directs all field operations and report preparation. Mr. Christensen has a Masters Degree in Engineering Geology and Hydrogeology with over 12 years of experience in Geotechnical Testing and Data Evaluation.

ATI Geologica completed five (5) Cone Penetration Tests to delineate soil stratigraphy and determine engineering parameters for a proposed development in Parish, FL. The tests were performed using a track mounted Geoprobe 7730DT anchored using two helical anchors. An electronic piezocone manufactured by Vertek was advanced at a rate of approximately 2 cm/s. The data was recorded using the Vertek DataPack and their proprietary data acquisition software. The raw data was then processed to obtain graphs of cone resistance, friction ratio, pore pressure and soil behaviour type. Additional data including estimated geotechnical parameters were also plotted and provided.

The original plan was for the five CPTs to evaluate conditions to a depth of 30 feet (ft). However, the tests were continued to depths of 32 to 37 ft because it was suspected during testing that the very dense, weathered limestone stratum (which was of primary concern) may have been below that depth.

Each sounding produced a continuous profile without interruptions. The data was of a high quality and considered to be accurate and representative of the geological conditions.

Results showed that the water table was at or near the ground surface, which was confirmed by above-ground observations. The materials are presented mainly as complex interbedding sands, silty sands and sandy silts with occasional clayey layers. Layers with suspected gravel were encountered in two of the soundings.

Data is captured continuously by the sensors inside the CPT and processed to determine the Soil Behaviour Type. The results from one of the soundings are shown in the image below.
