Site diary

The site diary records every working day the conditions on site, the workforce, the work done and every event that may matter later: delays, additional work, inspections and deliveries. In Finland, when the General Conditions for Building Contracts YSE 1998 apply to the contract, the contractor responsible for site management (usually the main contractor) must ensure that a site diary is kept, with the work-related information and events recorded daily, unless otherwise agreed (YSE 1998, section 75).

What to record in the site diary

At least the date, the weather, the size of the workforce, the day's work stages and all deviations. A good rule of thumb: if something may later lead to a dispute, record it on the same day.

Particularly important are disruptions and delays with their causes, instructions given by the client, agreements on additional and variation work, and inspections with their results. Recorded afterwards, their value as evidence is weak.

Who signs

The diary is usually kept by the main contractor's responsible site manager. The diary is presented to the site supervisor, who signs to acknowledge having seen it (YSE 1998, s. 75(4)). The practice is agreed in the contract or at the start-up meeting.

How this template works

The form stores the entered data in your browser's storage, so you can continue later on the same device. Nothing is sent to a server. The Save PDF button opens the browser's print dialog: choose “Save as PDF” as the destination.

The Fetch weather data button fetches the temperatures at 7:00 and 13:00, the weather and the wind for the diary date from the nearest observation station of the Finnish Meteorological Institute. The location is taken from the device's positioning (if you allow it) or from the Town field. Only the location and the date are sent to the Finnish Meteorological Institute, no other data from the form. The station and the time of the search are recorded in the Source of the weather data field. Weather data: Finnish Meteorological Institute, open data, CC BY 4.0.
