About this Project

AEG provided topographic survey and geotechnical investigation services for the proposed tank foundations located at four DRPA sites:

  • Commodore Barry Bridge
  • PATCO Lindenwold
  • Ben Franklin Bridge
  • Betsy Ross Bridge

This project involved four above-ground storage tanks with 10,000-gallon capacity and approximately 15 feet by 60 feet concrete foundations. AEG’s scope of work for this project included topographic surveys, geotechnical investigations with associated laboratory testing, and preparing a report presenting the results and preliminary recommendations for foundation design.

The survey scope of work included a one-day topographic survey at each site, marking the proposed boring locations. The point file from each topographic survey was processed and compiled into a base plan provided to the Client in digital format.

The geotechnical investigation scope included four borings (one at each site), laboratory soil classification testing, and a report presenting the findings. The borings extended to a maximum depth of 25 feet below the existing site grades to investigate the subsurface materials and to obtain data to provide parameters for foundation design. The borings were continuous Standard Penetration Test (SPT) soil samples in two-foot intervals. AEG provided full-time drilling oversight, boring logging, and visual classification of sampled soils. AEG retained soil samples to obtain index and engineering properties within our in-house AASHTO-Accredited Laboratory. AEG then prepared a letter-style report presenting each project site’s published soil and geologic characteristics. The report also showed the results of the subsurface investigations, laboratory testing, recommendations for the design and construction of foundations, and earthwork recommendations at the proposed tank sites.
