The work diary is the page for today on site. The supervisor and the client ask what happened. If it stays in your head or in a group, by evening you no longer remember who worked and what arrived.

What goes in the diary every day

• Who worked, by trade
• What was done, and where on site
• Material that arrived, including the delivery note
• What was delayed, and why
• The site manager’s signature

The general site register stays on site for the safety rules. The daily diary is what you write each day so it is clear what happened. Do not mix the two.

No Excel at seven in the evening

Excel is fine at the office. On site, open the app, photograph the delivery note or the receipt, and write a line about the day. It goes into that project’s diary.
