Excavation Support Design

GZA is routinely engaged in the design of support of excavation systems required for underground foundation and utility construction.

For both temporary and permanent support systems, GZA uses state-of-the-art modeling methods and other analytical tools including finite element analyses to prepare complete design packages from simple cantilever wall systems to braced excavation systems for  deep cuts requiring multiple support levels including:

  • Internally Braced Excavations
  • Tieback Supported Excavations
  • Tierod & Deadmen Supported Excavations
  • Soldier Pile and Lagging Walls
  • Secant and Tangent Pile Walls
  • Soil-Mix Walls
  • Sheet Pile Walls
  • Slurry Walls
  • Soil Nail Wall
  • Mechanically Stabilized Earth Walls
  • Retaining Walls
