Provided comprehensive geotechnical engineering services for the Custer Avenue CSO Relief Storage Vault project which were performed in two Phases. We evaluated the soil conditions and groundwater levels at the site, and provided recommendations concerning site development and foundation design and construction recommendations for the proposed storage vault. The proposed vault is a new five (5) million gallon buried underground stormwater vault retention consisting of cast-in-place concrete with side walls, overflow weir and box culvert by-pass to storage vault. The foot print of the vault is 58,000 square feet, City of Atlanta, Georgia.

Provided comprehensive geotechnical explorations, seismic study, and foundations evaluations and recommendations. Our recommendations consisted of deep foundations and shallow mat foundations. The project is a seven (7.0) million gallon (MG) buried underground stormwater vault retention consisting of cast-in-place concrete beams, columns with side walls, overflow weir and box culvert by-pass to storage vault. The foot print of the vault is approximately 90,000 square feet. In addition, we provided design recommendations for the proposed stormwater pond area which is approximately 780,000 square feet and is located on the SW corner of the intersection of Martin and Little Streets, Atlanta, Georgia.
