About this file
This is a geotechnical boring exploration report prepared for the Missouri Department of Transportation (MoDOT) for Project #24-5282 located in Poplar Bluff, Missouri. The report documents subsurface soil and geological conditions at the project site through six boreholes (B-1 through B-5, with B-6 designated as an alternate) drilled on May 15, 2024. The exploration was conducted using solid flight augers with a 4-inch hole diameter by CFS Engineers, the drilling contractor, with results logged and checked by engineering staff. The boring location plan identifies five primary boring locations across the 1100 W. Cambridge Circle Drive site in Kansas City, Kansas, as shown on the attached map.
The geotechnical investigation reveals subsurface conditions consisting primarily of fill materials including lean clay, fat clay with gravel content, and sawdust layers overlying native clay soils. Boring depths range from 4.6 feet to 20.0 feet, with bedrock encountered at varying depths (4.6, 7.4, and 18.7 feet in boreholes B-4, B-6, and B-2 respectively). Most boreholes encountered no free water at the time of drilling, during drilling completion, or after drilling, except boring B-5 which encountered groundwater at 14.50 feet during drilling and 15.00 feet at drilling completion. Standard penetration test (SPT) results and soil classification data are recorded for each boring, providing N-values and unconfined compression test results to support geotechnical design analysis for the MoDOT construction project.
