Record it once, where you see it.
ARCH turns the phone in your pocket into the whole site kit: notes, readings, photographs and the structure's history, working with no signal and sent when there is.
Say what you see. ARCH files it.
On a ladder or in waders, tap speak and talk. ARCH works out which element you mean, the condition you gave it, the defect and where it is, or the dimension you just measured. It happens on the phone itself, so it works with no signal and costs nothing.
- Filed as element, defect, dimension or general note, in your own words
- "Crack" becomes "fracture" automatically
- Tap any note to change how it was filed
- One tap writes your grades, words and measurements into the report

Underwater work without the paperwork.
Five sounding sections and radials at every abutment and pier. Type or read out the bed level, press Enter, and move on. The change against the previous examination is worked out and coloured if it matters.
- Datum and live water level worked out for you
- Falls of more than 0.15 m flagged as possible scour
- Bed profiles draw as you go, against previous and penultimate
- Excel, PDF and picture packs for the client system, straight from site
- The same readings print in the report appendices: nothing typed twice
The details that matter on site.
No signal, no problem
Readings, photographs and notes are saved on the device first and sent when there is coverage.
Any device
Start on the phone, finish on the tablet. The examination follows the examiner and nothing waiting is lost.
Reactive work
A bridge strike or a flood isn't in the work bank. Raise the examination there and then, structure and all.
Photographs that number themselves
Take them in order and they're P1, P2, P3. Reorder later and every reference in the report follows.
The history in your pocket
Previous reports and office-checked extracts travel with the examination, as context only, never as today's answers.

We'll load your work bank and show an examination from site notes to approval.
