What is the difference between a site report and a construction diary?

A site report (Bautagesbericht) covers a single day on the construction site. A construction diary (Bautagebuch) is the collection of all daily site reports for an entire project, forming a complete chronological record.

Who is responsible for writing the construction site report?

Typically the site manager (Bauleiter) or foreman is responsible. For projects supervised by an architect under HOAI service phase 8, the architect must maintain documentation. With docubau, anyone on site can submit entries via WhatsApp.

What Is a Construction Site Report?

A construction site report (Bautagesbericht) is a daily record of everything that happens on a building site. It serves as proof of progress, a communication tool for project stakeholders, and a legal document in case of disputes.

Unlike a full construction diary, a site report typically covers one specific day and is often prepared by the site manager or foreman at the end of each working day.

What Must a Site Report Contain?

Every complete construction site report should include the following sections:

Project information – Project name, address, report number, and date
Weather conditions – Temperature, precipitation, wind speed, and general conditions (sunny, overcast, rain, frost)
Working hours – Start and end times of work on site
Workforce present – Number of workers per trade (e.g., 4 electricians, 6 concrete workers)
Work performed – Detailed description of activities completed
Materials delivered – Type, quantity, and supplier
Machinery and equipment – Equipment in use, including rental machinery
Special incidents – Accidents, defects discovered, delays, visitor notes
Photos – Timestamped images documenting progress or issues

Example: Filled-Out Site Report

Here is a simplified example of a daily site report entry:
