Site evidenceFor contractors & subcontractors
Do the work. Get paid for all of it.
The site diary app that captures labour, plant, progress, delays and instructions as the work happens. So when a delay, an extra or a valuation is questioned, you hold a dated, structured record, and get paid for what you actually did, not just what you can remember.
The 30-day pilot is free. No card required.
Today’s daily record, Fri 23 Oct 2026: labour, plant and progress captured as it happens.
ONE DAILY
RECORD.
READY WHEN COMMERCIAL NEEDS IT.
The old way
What it replaces
The same battered paper diary, failing the five handoffs every paper record has to survive.
The diary gets done
Thursday and Friday, written from memory on Monday.
The old way, in six steps you can page through: the paper diary gets written days late, chased for a signature, photographed badly, buried in a group chat and filed nowhere. Months later nobody can say what happened on a given day.
The problem isn’t doing the work. It’s getting paid for all of it.
Logged on the day
Labour, plant, progress, delays and photos, captured as it happens.
Flagged as commercial
Standing time, an instruction or an extra surfaced as a recoverable event.
Acknowledged by the client
A dated record the other side has seen. Much harder to deny later.
The dispute room
£184,320 rejected. The records exist. Find them.
An illustrative construction dispute you can actually play. The same evidence, found twice: once in a normal filing system, once in Site Chronicle. Your time against your own filing.

There is insufficient contemporaneous evidence to substantiate the labour and plant resources claimed in connection with the instructed drainage diversion (SI-042). The sums claimed are not agreed.
Illustrative scenario: fictional companies and figures
Five pieces of evidence, buried where your records actually live. The clock is running.
How it works

What happens after the pilot
The product
What the record has to carry
A site diary that is fast for the crew, structured for the commercial team, and reviewable months later.
Fast site diaries
A full day (labour, plant, materials, progress, weather, photos) logged in minutes on a phone, with yesterday’s crew copied forward in one tap.
Labour & plant evidence
Who was on, what ran, hours and fleet numbers: structured records you can search and total, not scribble you can’t.
Delays & extras you can substantiate
What happened, when, who caused it and which labour and plant it affected: the contemporaneous basis for substantiating a compensation event or a variation, recorded on the day.
Contextual photographs
Photos attach to the day, the delay or the record they evidence, captioned, not lost in a camera roll.
Client acknowledgement & comments
A client representative can acknowledge, comment on or dispute the daily record from a link. No app, no login.
Management reporting & exports
Live project visibility for the office, and one-click PDF, Excel and timesheet outputs for the commercial team.
Proof
Built and proven on live UK projects
Site Chronicle is in daily use on live UK subcontractor projects, refined against the practical requirements of site teams and commercial managers. Here is what that looks like in practice.
Project 1
£274,000
Increase in the certified amount
An interim application of ~£1.6m was initially certified at ~£1.33m. One week of contemporaneous diaries (labour, plant and progress recorded as the work happened) supported the valuation, and the certificate was revised to ~£1.6m. The diaries did not replace the contractual valuation; they gave the commercial team an immediate, structured record to support the amount applied for.
Project 2
£338,000
Additional instructed work claimed and paid
Additional work was raised on site with no instruction reference. Because Site Chronicle requires instructed work to be linked to an instruction, the site team flagged the gap, and the commercial team secured the instruction before the work accumulated. The next ~3 months were recorded against it: activities, labour, plant and every hour, on client-signed daily records. ~£338,000 was claimed and paid in full. The records supported the valuation but did not, by themselves, determine contractual entitlement.

Built from decades of construction commercial and claims experience.
Built from direct commercial experience
Site Chronicle was created by a construction commercial and claims specialist supporting subcontractors across UK infrastructure and civil-engineering projects.
Site Chronicle is designed specifically around the evidence contractors need to substantiate labour, plant, progress, instructions, delay, disruption and change.
