EGSci provided on-call geophysical services in support of the City of Atlanta’s sewer system rehabilitation project under Clean Water Atlanta.
Services included monitoring construction vibrations near existing structures and ground penetrating radar investigations to assist in the location of buried sewer manholes and potential subsurface voids beneath roads related to leaking sewer lines.
EGSci conducted environmental site assessments and geotechnical investigations on several properties, in support of land transactions for the City of Auburn.
- New Recreational Area – EGSci conducted a Phase I investigation for a small plot of land, intended to be the location of a proposed recreational area, within the city of Auburn, GA.
- Expansion of Existing Recreational Area – EGSci conducted a Phase I investigation in support of a proposed expansion of an existing recreation area. The expansion consisted of an approximately 7-acre wooded site. In addition, a Phase II investigation, consisting of a ground penetrating radar investigation and soil sampling/testing was also completed for the site.
- Industrial Park – EGSci conducted a Phase I investigation and preliminary geotechnical investigation, consisting of 16 soil borings, for an approximately 20 acre site that the City of Auburn was interested in developing into an industrial park.
DeKalb County, Georgia
EGSci managed and led field personnel for a subsurface utility exploration for a drainage system project at various locations throughout the county. Data was collected, analyzed and reported utilizing ground penetrating radar, radio frequency detection and magnetometer methods to detect utilities.
Gwinnett County, Georgia
EGSci conducted a seismic refraction investigation in support of a jack and bore project for installing a new water line along McGinnis Ferry Road. The interpreted seismic refraction data was used to map stratigraphy across a stream and the adjacent banks that was the target of the jack and bore project. The interpreted seismic refraction data was used as a supplement to the geotechnical investigation which had only limited access to the site on one side of the stream.
Walton County, Georgia
A geophysical investigation was conducted in conjunction with a geotechnical investigation as part of the site characterization for a proposed dam. Data collected consisted of Seismic Refraction and MASW that were used to map the depth to rock and determine the seismic classification.
