Provided geotechnical engineering services to support the design of a new Pump Station and approximately 1000 LF of force main with 3 feet of cover in Pinellas County, Florida.

Provided subsurface investigations and associated recommendations for this project which was intended to improve the water quality of the effluent from the Combined Sewer Outfall (CSO) system of the Stockade sub-basin in southeast Atlanta. The plan included the design of approximately 52,000 LF of new sanitary sewer and 11,000 LF of new storm sewers including tunneling under I-20.

Provided the planned structures included an electrical building, an odor control building, and a wet well for the proposed pump station The wet well shaft was approximately 200 feet deep with circular concrete walls to house pumps and store wastewater.The excavation for the shaft consisted of open cut to top of rock followed by rock excavation by blasting or by shoring the excavation using soldier piles and lagging system. We performed geotechnical explorations, rock coring and laboratory testing to arrive with the most cost-effective foundation system to support the construction.

Served as the owner’s representative onsite as well as providing construction materials testing and inspection services, such as concrete and soils testing, and offsite lab concrete compression testing. Also provided remediation solutions associated with the removal and replacement of a 24” groundwater runoff drain pipe on the northside of the reservoir dam.
