Attach a soil investigation report and the Structural Agent reads it the way you would: soil strata, SPT N-values, groundwater, lab results. Ask for the interpretation you need, from a summary table of design parameters to a preliminary ERSS (earth retaining and stabilizing structure) concept to take into scheme design.
Preliminary means preliminary. The agent’s interpretation and concepts are a starting point for the geotechnical and structural engineers of record, not a substitute for them. Verify parameters against the source report before any design rests on them.
Attach the SI report with the + button, or tag it with @ if it is already in your Files area. Multi-hundred-page reports are fine; tell the agent which boreholes matter if you know.

Ask for the interpretation you need
Example: parameter summary
@SI_Report.pdf Summarize the soil profile at boreholes BH-3through BH-6: strata, SPT N-values, unit weights, undrainedshear strengths, and groundwater levels. Present as a tableI can use for retaining wall design.
Example: specific questions
@SI_Report.pdf What does the report recommend for excavationsupport? Is there a soft clay layer below the proposedformation level, and how thick is it?

Check the output against the source
The agent reports what the document says and where it says it. Spot-check the values against the borelogs before they go into a calc.
With the ground model established, describe the excavation and your constraints:
Example
Using the soil profile from BH-3 to BH-6, propose preliminaryERSS options for a 9 m deep excavation, 40 m x 25 m in plan.Constraints: an existing building 6 m from the north face,groundwater at 2.5 m depth. Compare a strutted sheet pile wallagainst a bored pile wall: indicative wall depth, strut levels,and the main risks of each. State every assumption.
The agent lays out the options with its assumptions stated, so each one can be checked and taken forward or discarded. Ask for the comparison as a table or a short report (in your company’s format, if your templates are set up).Follow-ups sharpen the concept:
Take the strutted sheet pile option: what wall embedment does afirst-pass stability check suggest, and which soil layer governs?Show the calculation and the assumptions.
Give the constraints, get a better concept. Adjacent structures, groundwater, headroom limits, and sequencing drive ERSS selection more than the soil does. Name them in the prompt.
The same pattern covers temporary works: attach the drawings or the contractor’s submission and ask for a first-pass check.
