Narrow the field, not the engineering.

Record preliminary site conditions and identify the geotechnical and structural information still required before any foundation family is selected.

Project inputs

Defaults are examples, not recommendations. Replace them with traceable project assumptions.

A field description does not replace a geotechnical classification.
Used only as an installation-logistics signal.
Consider lease and decommissioning obligations.
Confirm design frost depth locally.
A qualitative constructability input.
Use boring observations when available.
Chemistry testing still governs.
Leave blank when no test result exists.
Leave blank when unknown.
Loads must be paired with geotechnical resistance before sizing.

Screening result

Updated from the inputs at left.

Preliminary decision support only. Confirm inputs, governing standards and final conclusions with the responsible qualified professional before design, procurement or construction.

Method and assumptions

The tool applies a transparent rule-based score to five foundation families: driven piles, helical ground screws, concrete, ballast and rock anchors. Soil, scale, reversibility, frost, slope, groundwater and optional investigation inputs move the relative screening score.

  • The score means “worth evaluating,” not structural adequacy.
  • The explanations show why a candidate moved up or down.
  • The missing-data list is part of the result, not an afterthought.
