Project scope and field context
ATI Companies Drilling Team completed a DPT Drilling, Sampling and Monitoring Wells installations project at the Tampa International Airport which included 30 Soil Borings to approximately 15 ft below land surface and the installation of 10 - 2 inch Monitoring Wells to 15 ft below land surface, via Direct Push Technology (DPT) methods. The Monitoring Wells were installed using auger attachments. Using a Geoprobe 7730 DT, Ambient Technologies, Inc. (ATI) was able to accomplish the required Scope Of Work which included Concrete Coring for every location and the installation of 12 inch by 8 inch Aircraft Rated Bolt Down Manhole manufactured by CAVOTEC. These are reinforced manholes with fiberglass casing extending down approximately 18-inches. Soil Borings were grouted and patched once completed. Monitoring Wells required development of up to 30 minutes. The Concrete Coring needed at the tarmac was 16 inches with 8-inches of crushed concrete base underlying for a total of 24 inches. Project Services: § 30 soil borings to approximately 15-feet below land surface using DPT. Hand cleared to 5-feet and Macro Core to TD. § Install 10 Monitor Wells (2-inch diameter) to 15-feet below land surface with 10 ft of PVC 0.010 slotted screen. Hand cleared to 5-feet and Macro Core to TD. § Monitoring Wells to be completed with a 16-inch round concrete pad and 12-inch airport rated bolt down MHC (CAVOTEC). § All locations had to be cored with ~24 inches concrete thickness.
