The Site Diary App That Keeps Records You Can Rely On
A site diary app is a phone or tablet tool that records what actually happened on a construction site each day — who was there, what work was done, the weather and any incidents — so you are not relying on a paper daybook or memory. Valegrid Flow keeps a daily site diary for every project and every customer site, with timestamped photos, weather captured automatically at first clock-in and sign-off, daily H&S checks and manager sign-off. Every day exports to PDF, and the records are built to stand up in a payment dispute.
A construction site diary that fills itself in
Half the reason paper diaries fail is that nobody has time to write them. Valegrid Flow captures the weather automatically at first clock-in and again at sign-off — temperature, humidity and wind — and every photo is timestamped the moment it is taken. Add events to the day's timeline and tick off the daily H&S checks, and the diary builds itself as the day goes on.
Daily site records that stand up in a payment dispute
A diary is only worth keeping if it holds up when money is on the line. Every day in Valegrid Flow carries a manager sign-off, and you can export a PDF per day or per week — including separate versions per customer, so you only send each client what belongs to their site. The records are built to stand up in a payment dispute, not just to look tidy.
One site diary for every crew on the job
Most site diary software only tracks employed staff. Valegrid Flow records price-work crew attendance alongside employed labour, so the diary shows everyone who was actually on site that day. A live 'who is on site' view with a headcount means you can see the picture right now, not just after the fact.
A daily diary per project and per customer site
If you run gangs across several sites for several clients, one big diary is useless. Valegrid Flow keeps a separate daily diary for each project and each customer site, so the record for one job never gets tangled up with another — and the per-customer PDF export follows the same split.
How it works
- Step 1
Clock in and the day starts itself
At the first clock-in, Valegrid Flow records the weather automatically — temperature, humidity and wind — and the live 'who is on site' view starts counting heads, including price-work crews alongside employed labour.
- Step 2
Record the day as it happens
Take timestamped photos with a full-screen viewer, log events on the day's timeline and complete the daily H&S checks — all against the right project and customer site.
- Step 3
Sign off and export
The manager signs the day off, weather is captured again at sign-off, and you can export a PDF per day or per week — with per-customer versions ready to send.
Frequently asked questions
- What is a site diary app?
- A site diary app replaces the paper site daybook with a daily digital record of a construction site: who was on site, what happened, the weather and any incidents. Valegrid Flow keeps one diary per project and per customer site, with timestamped photos, an events timeline, daily H&S checks and manager sign-off, so there is a signed record for every working day.
- Does Valegrid Flow record site weather automatically?
- Yes. Weather is captured automatically at the first clock-in of the day and again at sign-off, recording temperature, humidity and wind. Nobody has to remember to write it down, and you have an objective weather record for every day on every site — useful when weather delays are questioned later.
- Can I use the site diary in a payment dispute?
- That is what the records are built for. Each day carries timestamped photos, automatically captured weather, an events timeline, attendance for both employed labour and price-work crews, and a manager sign-off. You can export it all as a PDF per day or per week, including per-customer versions, so you can hand over exactly the evidence for the site in question.
- Does the site diary cover price-work crews as well as employed staff?
- Yes. Valegrid Flow records price-work crew attendance alongside employed labour in the same daily diary, and the live 'who is on site' view shows a headcount of everyone currently on site. The diary reflects the whole workforce on the job, not just the people on the payroll.
Start keeping site records that back you up
