Deep Foundation Expertise

Deep foundations provide the key support for a wide range of buildings, bridges, towers, dams and other massive structures. The success of deep foundations is dependent upon a multitude of factors including but not limited to the type of pile and the type of driving equipment used to install them.

The foundation design and installation method for your project can be determined considering the unique and often widely varying soil conditions, and different magnitude and nature of applied loads. Each phase of the design, installation, inspection, and quality assurance testing is critical to the success of a deep foundation system in predicting if it meets its intended purpose without compromise. Unfortunately, once the building is completed, the foundation lies buried within the ground and cannot be conveniently reached for assessment or repair.

Our services for Deep Foundations include design and construction recommendations for:

  • Drilled shafts (conventional and base grouted)
  • Auger cast-in-situ piles (conventional CFA and drilled placement piles)
  • Micropiles
  • Driven pies

Our Earth Retention System expertise includes design and construction recommendations for different types of earth retention structures including:

  • Mechanically stabilized earth (MSE) walls
  • Sheet pile walls
  • Soldier pile and lagging walls
  • Secant and tangent pile walls
  • Soil-nail walls

Stabilizing a slope generally requires a solution unique to the given site conditions since all slopes are inherently different. UES has evaluated numerous unstable slopes requiring stabilization. We utilize the following methods:

  • Soil nails
  • Micopiles
  • Geosynthetics
  • Reconfiguring slopes, improving surface and subsurface draining
  • Buttressing

Our knowledge of Earthquake Engineering to evaluate site seismicity and potential seismic hazards requires the following capabilities:

  • Site-specific characterization of design ground motions including PSHA, site response analysis, and development of motions for dynamic structural analyses.
  • Analysis and characterization of geo-seismic hazards such as liquefaction and lateral spreading.
  • Seismic soil-structure interaction analyses for foundation design and evaluating combined foundation-superstructure demands and performance.
