General Excavations

Designers Knowledge Base


Investigate site topography, ground conditions and slope stability. What are the types and use of adjacent property and what are the length and location of any temporary roads and traffic routes to tip? Where are existing services?

Some design options for hazard reduction

  • design to avoid possibility of undermining adjacent structures
  • consider location of hard routes and tip sites which have least impact on construction and the local community
  • ensure ground investigation will detect local contamination
  • waterlogged ground
  • where there is limited working space consider excavations within piled supports
  • consider shoring options for adjacent structures to maximise working space within site excavation
  • when considering bored pile side supports in contaminated ground plan for handling and disposal of spoil
