Mr. Hewitt began his career performing shallow geophysical investigations throughout Florida, South Carolina, and Houston, Texas. These investigations used primarily ground penetrating radar (GPR) but also included electromagnetic (EM-31, EM-61, and EM-96) and seismic surveys.

Mr. Hewitt continued his career in ground subsidence performing investigations to find the probable cause of subsidence in residential and commercial structures and FDOT roadways and properties.

To date, Mr. Hewitt has performed over 750 subsidence investigations and assisted in approximately 250 other subsidence investigations for insurance companies, public adjusters, attorneys, homeowners, private businesses, and government agencies. These investigation were performed in Pinellas, Hillsborough, Pasco, Hernando, Sumter, Marion, Alachua, Manatee, Sarasota, Orange, Levy, Polk, Okeechobee, Highlands, Collier, Lee, Charlotte, Hardee, and Seminole Counties.

The ground subsidence investigations involved the management of all aspects of the project including: supervision of field crews, the performance and placement of hand augers, test pits, floor elevation surveys, and geophysical performance and supervision, writing of reports that detail the study and results. In addition, Mr. Hewitt has monitored the compaction grouting and the installation of pin piles.

David has a B.S. in Geology from University of South Florida and is a Licensed Professional Geologist – Florida P.G. #2227.
