Make your infrastructure last.
Photograph a structure in one visit. ISNAD’s AI reads every photo, an engineer confirms what it finds, and you know its condition, what to repair, and how many years that repair buys.
Preservation
A bridge’s life is decided by when you act.
Small defects left too long become major repairs, then replacements. ISNAD shows the condition of every structure, what each repair costs and what waiting costs — so the budget buys the most years of service.
Know the condition
Every structure rated the same way, by one signed method.
Act at the right time
Repairs ranked by urgency, cost and what deferring them costs.
Extend the life
Remaining life tracked visit by visit, as a range you can plan on.
How it works
One visit. One signed report.
- 01
Snap
Photograph each element with a phone. Position and heading are recorded with every photo.
- 02
The AI reads
Every photo is read in seconds: each defect named and boxed on the picture.
- 03
Confirm
One tap per finding. Tape only the serious ones; the rest are sized from the photo.
- 04
Rated
The signed method sets each condition state, the structure’s index and the repair bill.
- 05
Preserved
The engineer signs. The plan says what to repair, when, and the years it adds.
On site
A camera, a tape, and ISNAD reads the structure.
No forms on site and no notes to type up later. The record is made at the defect, while the inspector is looking at it.
Snap
Photograph each element. The phone records where it was taken and which way it faced, which places the photo on the structure and on the defect sketch.
The AI names it
Seconds later the photo comes back with the defects it shows, each boxed: spalling, cracking, corrosion, a failed joint.
Confirm or decline
One tap each. A crack takes the width read on the crack card held beside it. Anything the AI missed, the inspector draws.
Tape only what costs money
Serious defects ask for a length and a width. The rest are sized from things of known size in the same photo, and labelled as estimated.
The AI names the defect; the method rates it. Condition states come from the signed method’s rules, never from the AI’s opinion, and every finding keeps its photo, its box, its rule and the name of the person who confirmed it.
Your network
Every structure you own, at a glance.
Condition, remaining life and the next repair for each one — so maintenance is planned, not reactive.

The AI
Five AI engines. One signed method.
The AI does the hours of desk work behind every condition report. The method keeps it consistent — the same evidence gives the same answer, whoever holds the camera. The engineer keeps it accountable.
Read
Every photograph read — and a stain told apart from a crack.
Draw
Each defect placed on the structure’s own drawings.
Rate
Condition by the method’s written rules, the federal rating beside it.
Price
A repair bill from dated rates — and the cost of waiting.
Project
Remaining life and value, always as a range.
Nothing leaves unsigned. The AI drafts; a licensed engineer decides.
Why owners trust it
AI speed. Engineering accountability.
Same evidence, same rating
One signed, versioned method — not whoever inspected.
Every number shows its source
The photograph, the measurement and the rule behind it.
Signed by an engineer
ISNAD signs the method; the engineer of record signs the report.
Your data stays yours
Never published, sold or pooled. Every use recorded.
For owners of bridges, tunnels, culverts and walls
Keep every structure standing longer.
