General information

The Construction Equipment Register (BGL) Online and the book are based on the same data material.

In terms of content, technical innovations and change requirements in construction practice have been mapped compared to 2020. For example, numerous new devices have been added, particularly in the areas of electromobility and alternative drives. In order to be able to map the large number of new appliance types in the existing structure, the previously purely numerical classification scheme was expanded to include an alphanumeric structure in individual groups. Nevertheless, the greatest possible continuity was generally maintained. The main structural elements: appliance group, appliance subgroup, appliance type, technical parameter(s) and the manufacturer-neutral average replacement value of the appliances remain structural components of this BGL 2025. All economic indicators, in particular the mean original values, have been updated.

In the online version of BGL 2025, the data will be updated as necessary to include new appliances and equipment.

To understand the navigation and the meaning of the terms, we recommend reading the basic information of the Construction Equipment Register.
