ATI Geologica completed five (5) Cone Penetration Tests to a depth of 25 feet to delineate soil stratigraphy. The tests were performed using a track-mounted TMG CPT-223 rig 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 software, CPTSND. The data was then processed using Vertek’s Coneplot to obtain the raw data and basic graphs and tables.

Four (4) cone penetration tests, three (CPT-01, -02 and -03) to depths of 25 ft below ground surface (bgs) and one (CPT-04) to 15 ft bgs. A dissipation test was performed at the base of CPT-04 at 16.01 ft bgs. No additional testing was requested.

The tests were extended at no extra cost beyond the requested 25 ft depth to confirm the presence of the softer material below the initial termination depth. CPT-1, -2 and -3 all confirmed the silty/clayey layerextending from approximately 20 ft bgs to the base of each of the soundings.

Each sounding ran continuously without disturbance or interruption and the data collected is considered to be accurate and representative of each respective location. The pore pressure sensor lost connection at times in CPTs 1, 2 and 3 however this did not affect the data collected by the other sensors which were functioning as normal.

Results and Highlights: The site was generally dry and sandy, the groundwater level was measured in CPT-3 at 5.66 ft bgs. The materials presented mainly as mixes of sands, silty sands and sandy silts with softer sandy/silty clays from 20 ft bgs.
