Site diary app
BRCKS app: site diary app for UK builders
BRCKS is a site diary app that fills itself from what your team already says in BRCKS Chat or on WhatsApp.
Labour, weather, deliveries, photos and decisions are filed by day into a construction site diary, dated and ready to export.
A real BRCKS site diary

Prefer to start with a blank daily record? Download the free site diary template. Fill in labour, weather, work, deliveries, instructions, visitors and photos. Review it at the end of the day rather than relying on memory.

What goes in a construction site diary
A good site diary answers one question: what happened on site that day? On a UK job that usually means:
- Who was on site, by trade and headcount.
- Weather, and whether it stopped work.
- Deliveries, and anything short or damaged.
- Work done, with photos.
- Instructions and decisions, and who gave them.
- Visitors, inspections and any incidents.
Most diaries fail because someone has to write all that at six o'clock, tired, from memory. So it gets skipped, and the record has gaps right where you need it.
How the diary fills itself from the site chat
Your site team and office already talk about the day as it happens. In BRCKS they do that in BRCKS Chat on their phone or in BRCKS Web. Subcontractors and clients can stay on WhatsApp, free.
BRCKS files each message, photo and voice note to the right job and the right day. A photo of a delivery becomes a delivery entry. "Rain stopped the roofers at 2" becomes a weather note. A voice note from the gaffer becomes searchable text.
At the end of the day the entry is already there. You read it, add anything missing, and move on. If you run several jobs over WhatsApp, see how WhatsApp project management keeps each job's messages apart.
What a daily entry looks like
Here is an example of one day on a made-up job, so you can see the shape of an entry. The names and details are illustrative.
Every line links back to the message, photo or voice note it came from.
Using the diary in a dispute or delay claim
Disputes come down to dates. When did the drawings arrive? Which days were lost to weather? Who agreed the change, and when?
A diary written at the time, with dated photos and the original messages behind it, is far stronger than one rebuilt from memory months later. It backs up an extension of time, a delay claim or a variation, and it helps settle a disagreement with a client before it turns into a formal dispute.
Because entries come from the chat as it happened, they carry the time each message was sent. You are not relying on someone remembering to write it up.
Exporting the diary for clients and handover
Export the diary for a day, a week or the whole job. Send a weekly summary to the client, attach a date range to a claim, or include the full record in the handover pack.

Site diary vs snag list: how they connect
The diary records what happened each day. A snag list records what still needs fixing. They are different jobs, but they sit on the same project in BRCKS.
When a snag is disputed, the diary shows who was on site the day the work was done. When a snag is closed, the fix photo appears in that day's entry. See how the snagging app handles the snag side.
The diary and snags are both part of our construction project management software for builders.
Site diary app questions
What is a site diary app?
A site diary app keeps the daily record of a construction job on your phone: labour, weather, deliveries, work done, photos and decisions, all dated.
Does someone still have to write the diary?
Not from scratch. BRCKS builds the entry from what the team says in BRCKS Chat or on WhatsApp during the day. You check it and add anything missing.
Can subcontractors add to the diary?
Yes. Subcontractors and clients can stay on WhatsApp, free. Their photos and messages are filed to the right job and day.
Can I export the site diary?
Yes. Export a day, a week or the whole job as a dated record for clients, claims or handover.
Is the site diary useful in a delay claim?
A diary written at the time, with dated photos and the original messages, is strong evidence for an extension of time or delay claim. It is much stronger than notes rebuilt later.
