Why a site diary matters
A well-kept site diary is the single most valuable document you can have if a construction dispute arises. Courts and adjudicators treat contemporaneous entries - notes made at the time, not reconstructed later - as reliable factual evidence. Entries about weather, workforce levels, instructions and delays can make the difference between winning and losing a claim.
The diary is equally useful for day-to-day management: tracking productivity, identifying recurring issues and providing a clear record for client or building control progress updates.
Columns included in the template
The template contains 60 pre-formatted blank rows, enough for a 12-week contract. Simply duplicate the sheet for longer projects.
What to record and how
Weather - note conditions that affected the work (rain, frost, high winds, extreme heat). This is critical for evidencing weather-related delays or concrete pour decisions.
Workers on Site - total headcount. If productivity is later disputed, the workforce level on any given day is key evidence.
Instructions Received / Given - record any verbal or written instruction from the client, architect, building control or other party. Note who gave the instruction, exactly what was said, and the date. Follow up verbal instructions in writing as soon as possible.
Issues & Delays - log anything that prevented normal progress: late deliveries, neighbour disputes, utility strikes, access problems, waiting for inspections. Be specific and factual.
