Site Diary Template: What to Record Daily

A site diary is the daily log of events on a construction site, kept by the site manager or supervisor. It overlaps with the daily report but is often a more personal, narrative record — the running account of what happened, who was there, and what affected the work. A site diary template ensures it's consistent enough to rely on when it matters, which is usually when a dispute arises months later.

This article explains what to record in a site diary and how a template helps.

Why the site diary matters

Like the daily report, the site diary's value is as contemporaneous evidence. When questions arise about delays, instructions, or events, the diary is the day-by-day account everyone refers back to. A complete, consistent diary is a powerful protection; a patchy one full of gaps is a liability. The discipline of recording every working day is what gives it weight.

What to record daily

A good site diary template prompts for, at minimum:

• Date and day.
• Weather — conditions and temperature, and any impact on work. (Weather is a common basis for delay claims, so log it every day.)
• Labour on site — companies, trades, numbers present.
• Plant and equipment on site.
• Work in progress — what was done, by area and trade.
• Deliveries — materials received and any issues.
• Visitors — clients, inspectors, authorities, and why.
• Instructions received — verbal or written, and from whom.
• Delays, disruptions, and stoppages — what happened and why.
• Incidents and near misses.
• Notable events — anything significant.
• Photos — visual record of the day.

Record instructions and verbal agreements

One thing the site diary captures especially well is informal instructions and verbal agreements — the "just do it this way" conversations that don't get formally documented but later become disputed. Noting who said what, when, in the diary creates a contemporaneous record of these exchanges. It's often the only record they'll ever have.

Capture delays as they happen

If work is held up — late information, access problems, another trade's delay, weather — record it on the day, with the cause and the impact. Reconstructing delay events after the fact from memory is weak; a daily diary entry made at the time is strong evidence for an extension of time.

Keep it factual and consistent

The diary should be a factual record, written the same way every day. Avoid opinion and blame; record what happened. Consistency matters more than eloquence — a brief, complete entry every day beats a detailed entry once a week.

Site diary vs daily report

The two overlap heavily and on many projects are effectively the same document. Where they differ, the daily report tends to be the formal structured submission, while the site diary is the site manager's running personal log. The key point is that something contemporaneous is recorded every day — whatever you call it.

Paper diary vs app

The traditional bound site diary is a single physical book — easy to lose, with photos kept separately and no office visibility until handed in. A digital site diary captures the same fields on a device, can pull weather automatically, attaches photos to each day's entry, and syncs immediately — keeping the record complete, backed up, and accessible.

Key takeaways

A site diary is the daily contemporaneous log of site events: weather, labour, plant, work in progress, deliveries, visitors, instructions, delays, and incidents, with photos. Record verbal instructions and delays as they happen, keep entries factual and consistent every working day, and don't leave gaps. A template makes the diary reliable — and a reliable diary is one of the best protections a project has.
