Geotechnology performed a subsurface exploration and provided foundation analysis and recommendations for the 10-story bed tower.
The construction of the 400,000 square foot, 339 bed facility also included a new emergency department, the hospital expansion, expansion of parking areas and attached tunnel connecting the proposed and existing facilities. Geotechnology explored the subsurface conditions, performed a site specific seismic study, and provided geotechnical recommendations for the design and construction of the building. Services included geotechnical drilling and sampling, laboratory testing and engineering analyses.
The project was the first one in DeSoto County, Mississippi to be designed and constructed in accordance with the International Building Code (IBC). Due to the high seismic risk and large design loads, a deep foundation system consisting of Augered Cast-In-Place piles was recommended. Soil characteristics and recommendations were provided for the design and construction of a concrete tunnel, which required a temporary dewatering system due to the shallow groundwater level. Detailed pavement recommendations were provide for the parking area expansion.
In addition to geotechnical engineering, Geotechnology performed construction observation and materials testing services. Our field engineers and representatives provided full-time observation and testing of the construction materials. These services included observation and testing of Augered Cast-In-Place piles, soil and asphalt placement, backfill of utility trenches, reinforcing steel placement, and grout and concrete sampling and testing.

In 2011 Geotechnology performed geotechnical subsurface exploration to provide design considerations for the design and construction of the planned 37,000 square foot cancer treatment center. The new facility will be located on an approximately 16 acre site southeast of the intersection of Interstate 55 and Butler Hill Road in South St. Louis County.
Geotechnical services included providing foundation recommendations and site grading considerations Geotechnical-related observations and consulting services were also provided during drilled pier construction related to the linear accelerator after which the depth required for construction of each pier was determined.

We were responsible for the geotechnical engineering and construction materials testing services for the construction of a six-story academic building.
We performed a subsurface exploration and provided foundation analysis and recommendations for the six-story $120 million structure, which featured an underground service loading dock. The foundation systems consisted of Augered Cast-In-Place piles. Our team explored the subsurface conditions, performed a site-specific seismic study and provided geotechnical recommendations for the design and construction of the building.
High groundwater conditions encountered at the site during construction hindered the process of foundation installation. The client requested consultation to determine what methods could be employed to allow for the installation of the piles. A dewatering system of deep wells was designed and constructed to lower the groundwater table. It was also recommended that a permanent under-slab drainage system be incorporated to help protect the slab against a future increase of the water table.
In addition to geotechnical engineering, field engineers and field representatives provided full-time construction observation and materials testing services. These services included observation and testing of Augered Cast-In-Place piles, static pile load tests, soil and asphalt placement, backfill of utility trenches, reinforcing steel placement and grout and concrete sampling and testing.

We performed pre-construction probing on the BJC Institute of Health, which is the largest building to be constructed on Washington University’s School of Medicine campus.
We were tasked with completing pre-construction probing to determine drilled pier bottoms and observed drilled pier installations for approximately 140 rock-bearing drilled pier foundations. Additionally, team members provided field and fabrication shop observations of structural steel members.
The 700,000-square-foot, 11-story $235 million building, which spans Metrolink light rail tracks, is a joint project between the Washington University School of Medicine and BJC HealthCare. The facility will house academic departments, support operations of Barnes-Jewish hospital and BioMed 21, a multi-disciplinary research initiative.
