Ft. Drum Base Expansion

Location: Ft. Drum, New York

Summary: Subsurface investigation and geotechnical evaluation services for multiple barracks, headquarters buildings, and maintenance buildings across the army base.

Services Provided:

  • Soil borings utilizing both ATV-mounted and a truck-mounted drill rigs.
  • Laboratory analysis
  • Comprehensive geotechnical evaluations for the projects.

ATL’s 40 plus years’ experience in executing geotechnical and environmental subsurface investigation programs has provided us with expertise in a wide variety of project types. As a result of comprehensive hands-on-training and valuable practical experience, our crews demonstrate proficiency in using a variety of sampling and data collection techniques specific to project requirements, and have gained a reputation for responsiveness and high quality workmanship.

ATL manages each subsurface investigation utilizing a centralized approach, which allows for a high level of efficiency in scheduling, coordination, and project control. Maintaining a full complement of subsurface equipment, including various types and sizes of drill rigs and diverse specialized support equipment, we offer flexibility in meeting the demands of unique mobilization and challenging access requirements. In addition, our in-house maintenance shop routinely performs preventative maintenance on our subsurface equipment and we take pride in minimizing potential delay due to equipment breakdown.
