TSI

Tecto Structural Intelligence

TSI reads photos of visible damage in structures together with engineering context, inspection history and technical knowledge. It reports what it sees, what that may mean and what to do next, and never treats a photo alone as proof that a structure is safe.

39,867knowledge units from 148 sources
724concrete grading rules

95%crack detection precision on test images it never saw

From Tecto's Stage 1 research, November 2026. Measured on held-out test sets; not a guarantee for every photo.

Highlights

Reads the photo in context
Element, material, scale and damage history
Backed by standards and research
Guidance from the US, Japan, Europe and beyond
A plain report, not a verdict
What it sees, what it may mean, what to do
Evidence-grounded conclusions
Every claim traced back to its source
Measured, with uncertainty
Scale and confidence always shown
Unknowns stay unknown
Missing context is never guessed

How it reasons

A careful reading, never a verdict

TSI keeps three things apart in everything it produces, so an observation is never mistaken for an engineering conclusion.

1
Observation
What the evidence directly supports.
A diagonal crack is visible on the beam surface, about 1.2 mm wide, subject to scale uncertainty.
2
Interpretation
What the pattern may fit, given the context.
Its direction may fit a shear-related pattern, but a photo alone can't confirm the cause.
3
Recommendation
What to consider doing next.
Have a qualified structural engineer inspect the beam, especially if the crack is new or growing.

Pick an example, change what's known about the photo and watch the report change. Less context means fewer conclusions, never more guessing.

Who it's for

Built for the people who look after buildings

TSI is in research and development; these are the people it is being built for.

Homeowners and residents
Photograph a crack or a damp patch and get a calm, plain explanation of what it may mean and when to call an engineer.
Building and site managers
Keep a dated, comparable record of damage across buildings, and see what needs attention first.
Engineers and inspectors
Start from structured observations with their sources, so site visits and reports begin a step ahead.

Scope

What TSI covers

TSI is built for six families of materials. The proof comes one family at a time, starting with concrete; the photo input, grading, recommendations and reports are already built for all six.

Stage 1 / 6In progress
Concrete
Plain, reinforced, prestressed and lightweight
Stage 2 / 6Next
Steel and other metals
Members, connections and corrosion
Stage 3 / 6Planned
Masonry
Brick, block and stone
Stage 4 / 6Planned
Timber
Structural timber and joints
Stage 5 / 6Planned
Soil, rock and waterways
Ground, slopes and water around structures
Stage 6 / 6Planned
Coatings, render, joints and bearings
Protective and functional systems
