Many times the substructure goes unnoticed, but it is a very important aspect of the overall project. Whether the supporting soil stratum is like weak clay found in south Louisiana, or hard rock found in central Arkansas, the CASE team is well experienced and prepared to work with either. The team has designed both shallow and deep foundations using several different construction methods for installation. CASE has developed a huge database of geotechnical information in the region and works closely with the geotechnical engineers during the design. The team is also capable of performing construction inspection services on its foundations and has experience working test pile programs. The team has overseen static pile load tests, pile dynamic analyses, and hammer efficiency and maintenance operations.
