The Site Diary and the Daily Record

Every site keeps a daily record. It is written for today and read in a dispute three years later.

For teams turning the site diary and the daily record into a repeatable record, the software website provides a useful operational reference for time, attendance and reporting workflows. It should be assessed alongside Chartered Institute of Building so the software choice remains grounded in site practice and applicable guidance.

What it contains

Labour on site, by trade and by subcontractor.

Plant on site and whether it was working.

Weather, which determines whether work was possible.

Progress against programme.

Deliveries, visitors, inspections.

Instructions received and given.

And events: an incident, a stoppage, a service strike, a neighbour complaint.

Why it matters later

Delay and disruption claims are argued from contemporaneous records, and the site diary is the primary one.

A claim that the works were delayed by late information is evidenced by what the diary shows about labour standing idle.

And the party with the better daily record usually prevails, which is an unglamorous fact about construction disputes and the main reason the diary is worth doing properly.

Where access data helps

Labour counts, by subcontractor, without anybody counting.

Which removes the least reliable part of the diary: a supervisor's estimate written at the end of a long day.

Plant arrival and departure, where the gate records vehicles.

And a defensible timestamp, which a handwritten entry does not have.

Where it does not

Access data records presence, not productivity.

A diary entry saying twelve bricklayers were on site and unable to work because the scaffold was incomplete is the valuable record.

The access system provides the twelve. A person provides the rest, and the rest is what a claim turns on.

Which is why the access data should feed the diary rather than replace it, and a site that stops writing the narrative because the numbers are automatic has lost the part that mattered.

Making it contemporaneous

Written the same day, by somebody who was there.

Not reconstructed at the end of the week, which destroys its evidential value — and which is visible to anybody examining it later, because the handwriting, the detail and the timestamps give it away.

A short entry written daily beats a full one written weekly, and that is the practical advice.

Photographs

Dated, located, and taken as a routine rather than when something goes wrong.

A weekly photographic record of each area costs half an hour and answers questions nobody knew to ask.

Metadata intact, because a photograph stripped of its timestamp is much weaker evidence.

And stored somewhere that survives the project, which is the failure: photographs on a phone that leaves with the person.

Retention

Longer than anybody expects.

Limitation periods for construction disputes run to several years after completion in most jurisdictions, and longer for some defect claims.

Which means the diary, the access records and the photographs have to be archived at handover rather than left on a site system that is decommissioned.

Agree the archive at project start, because at handover everybody is busy and the records are the last thing anybody thinks about.

The measure

Days with a diary entry, as a proportion, which should be every working day and rarely is.

Entries written the same day against entries written later.

And whether the labour counts in the diary reconcile with the access records, which is a two-minute check that validates both.

Who writes it

Somebody on site, not in an office.

And ideally the same person most days, because consistency of detail is what makes a series of entries readable as a record rather than as fragments.

Where it rotates, a template keeps the content comparable — the same headings every day, so an absent line means something rather than nothing.

What not to put in it

Opinions about individuals.

Speculation about fault after an incident, which will be read by everybody involved in the dispute that follows and rarely helps the writer.

Commercial positioning, which is what correspondence is for.

The diary is a record of what happened. A diary that argues is a weaker record than one that observes, and it is examined as closely as any other document.
