Drilling and sampling of soils and bedrock for a medical software development company campus. Structures include several multi-story, below-grade parking ramps; a 5,200-seat auditorium; an 11,000 auditorium; a 300,000 square-foot training center; a solar panel array field; and wind turbines. Site foundations used include spread footings, drilled pilings, and micropiles. We are continuing to provide geotechnical engineering analyses for the variable site conditions and building loads for the expansions at the main campus, including the Castaway, Sci-Fi, Restaurant 42, and Bakery structures.

Drilling, geotechnical analyses and/or materials testing for numerous projects at UW-Madison, including Camp Randall South End Zone improvements, the School of Veterinary Medicine addition, the Nicholas Recreation Center and the Kohl Center addition.

Hollow-stem auger and mud rotary drilling for geotechnical exploration for HNTB Corporation. Multiple drilling rigs on site to perform soil borings for the North Leg, West Leg, and Core sections of the project. Soil borings performed up to 200 feet deep. Coordination required with Milwaukee County Highway Department for traffic control.

Mud rotary drilling and hollow-stem auger drilling methods used for geotechnical exploration. Bedrock was cored to depths of 320 feet. Field work included packer testing of the bedrock during the coring. We installed piezometers into the boreholes for slug testing and long-term water level readings to calculate groundwater permeability rates of the bedrock. Overall, we were on the project site for 7 months.

Geotechnical and environmental drilling and sampling for new chilled water and steam facility serving the UW-Madison campus. Installed monitoring wells into bedrock and performed slug testing of the wells for groundwater permeability rate calculations.

Soils & Engineering Services was part of the design team for this project, which was recognized as The Roads & Bridges top road project of 2017 (Stage 1). We provided hollow-stem auger and mud rotary borings for roadways, sign structures, bridge structures, and retaining walls. Some of the bridge borings were performed at night to allow closure of one lane of traffic on USH 151. We performed pressuremeter tests of soft soils to provide additional information related to bearing capacity for proposed roadway embankments. Our field sampling included coring of bedrock at the Williamsburg Way bridge location. Our laboratory testing program included rate of consolidation of soft cohesive soils. We prepared geotechnical reports that included LRFD computations for bridge and retaining wall foundations.

Involved in each of the three design segments extending from the Illinois/Wisconsin state line to Madison, Wisconsin. Completed soil borings of roadways, sign structures, ITS structures, culverts, bridges, and retaining walls. Excavated test pits on existing roadway embankment side slopes and median side slopes to determine topsoil thickness and types of soils used to construct the outer portion of the embankments. Prepared geotechnical roadway and structure reports for the North Segment and geotechnical structure reports for the North and South Segments. Provided the soil sampling portion of the work scope for the Central Segment.

Geotechnical exploration and report for a replacement ice rink. The field work required use of a split-barrel sampler only, due to presence of chiller pipes in the floor. The purpose of the sampling was to determine the depth of frozen soils in addition to the soil types and depth to groundwater. The sampling was completed with our split-tower CME 550X inside of the existing building.
