The site diary is the record you fall back on when something is questioned months later. When a claim is cut, a delay is blamed on you, or the client says the work was not done on a given day, the diary is what shows what really happened.
It only works if it is filled in every day, by the person on site, while the day is still fresh. Keep the form short enough that a foreman finishes it before he leaves the site.
What goes in a daily site diary
- Date, project and who filled it inOne diary per site per day, signed by the supervisor or foreman.
- WeatherFine, cloudy, light rain, heavy rain, or work stopped by rain, with the time if it stopped work.
- Manpower on siteHeadcount by trade or subcontractor: welders, fitters, general workers and so on.
- Work done todayWhat was done and where, as a quantity where you can count it, for example 6 sets of handrail at Level 2.
- Delays and hours lostWhat held the work up (material, instruction, weather, client decision, site access, manpower, equipment) and how many hours were lost.
- Plant, deliveries, inspections, safetyMachinery on site, materials delivered (with the DO number), inspections or sign-offs, and any safety matter.
- Instructions and visitorsAny instruction from the client, consultant or main contractor, and who gave it.
- PhotosDated photos of the work, the delay or the delivery, with a line saying what each one shows.
How to keep a site diary that holds up
- Fill it in the same dayBefore leaving the site. A diary written days later is easy to question.
- Count, do not guessWrite quantities and headcounts, not “progress good”.
- Record every hold-upWith the cause and the hours lost. This is what supports an extension of time later.
- Take dated photosOf the work, the delay and the deliveries, and say what each one shows.
- Never rewrite an old dayIf something was wrong, add a correction with the reason. Keep the original readable.
Why the diary matters when things go wrong
- Extensions of time. Days lost to rain, late instructions or late materials need a daily record to back them up.
- Disputed claims. When the value of work done is questioned, the diary and its photos show what was done and when.
- Variations. An instruction recorded on the day it was given is much easier to price and claim as a variation.
- Paper gets lost. Diaries in a book or a WhatsApp group are hard to search and easy to lose when a supervisor leaves.
Do it in Raul instead
Raul’s Site Diary is a phone page your supervisors and foremen use to file each day’s report: weather, who was on site, progress, anything blocked with the hours lost, and up to 12 photos. It takes about a minute.
See the site diary app- It works with no signal. The entry is saved on the phone and sends itself when signal comes back.
- The office sees every site for the day, and the sites that did not file are named.
- An entry can be amended within 24 hours, then it locks. Site staff accounts are free.
