Ballard Green, Baltimore County, MD

  • The development plan for the 105-acre, 521-home mixed-use community called for depths of fill up to 12-18 feet over portions of existing gas pipelines.
  • The gas company required detailed evaluation to ensure that the fill loads would not impact the pipelines.
  • DMT soundings were used to estimate the soil stiffness and resulting settlement beneath each pipeline.
  • GTA was able to more accurately estimate soil settlements resulting in a less conservative analysis.
