Company materials identify design-build tunneling work as part of Zamborelli’s project history, including two tunnels installed beneath an existing emergency room to connect a new parking structure and hospital.

Applications

Where this work fits

  • Hospital and healthcare access improvements
  • Passageways beneath existing structures
  • Constrained excavation conditions
  • Design-build tunnel planning

Methods

Related capabilities

  • Tunnel excavation support
  • Shoring coordination
  • Under-structure sequencing
  • Field-fit equipment planning

Context

Why it is used

  • Useful when a required access path must pass below an operating structure
  • Requires careful planning around settlement, active operations, excavation support, ventilation, and sequencing
  • Often overlaps with shoring, underpinning, and limited-access work
