  • Options appraisal
  • Costed technical reports
  • Expert reports
02

Tools

What we calculate with, and what we draw with

The tool is chosen by the problem, not the other way round.

  • FLAC 3D — finite differences: ground and staged excavation
  • SOFiSTiK — finite elements: structures and tunnel segments
  • HEC-RAS — river hydraulics and flood analysis
  • AutoCAD — drafting and design drawings
  • Presto — quantities, budget, BC3 and progress certificates
  • BIM — model coordination when the tender requires it
  • Analytical methods — a mandatory check on every numerical model
  • Monitoring — calibration of the analysis against real site measurements
