How it works
From group chat to evidence-grade record, automatically
Construction Metric is a listener, not another app. It sits on the WhatsApp group your site already runs, and takes in the emails, photos, voice notes and files that arrive elsewhere, doing the record-keeping the industry has always struggled to do by hand.
Connect the group
We connect the listener to your project WhatsApp group with the group’s knowledge and consent. Capture is scoped per project: only the groups you connect, nothing else. Your team changes nothing about how it communicates.
Capture everything as it happens
Messages, photos and voice notes are captured in real time, each with its timestamp and author. Voice notes are transcribed automatically. Forward an email to the project inbox or drop files into the portal and they are filed the same way, against the project and the date, with the context that explains them.
Understand and categorise
AI reads each item and files it where it belongs: weather, labour, plant, deliveries, progress, delays and causes, instructions, health and safety. Plot and area references are recognised so records read by work front as well as by day.
Assemble the daily diary
Every evening the day’s activity becomes a structured, branded site diary. A named person can review and confirm it. The diary is filed to an ISO 19650 aligned structure alongside its evidence: photos, transcripts and source messages.
Keep a locked register
Confirmed diaries join a project register: timestamped, attributable, unedited and searchable. Months later you can ask when the access problem started or what was said about the parapet detail, and get the answer with its evidence.
Use it everywhere it pays
Daily emails to whoever needs them, portfolio dashboards for directors, exports for reports and valuations, and a defensible evidence base for extensions of time, loss and expense and final accounts.
Watch the sequence
A day on site, replayed
The site talks
Messages, photos and voice notes stream into the project WhatsApp group, exactly as they do today.
The listener understands
Key phrases are recognised and tagged: Progress, Delay, Variation, H&S. Voice notes are transcribed.
The diary assembles
Date, weather, labour, plant, progress and delays populate a structured record with the evidence attached.
The record is locked
The completed diary drops into the project register. Evidence-grade. Timestamped. Tamper-evident.
