FAQ

No, an operator’s license is not required for operating construction machinery. However, the employer is legally obligated to provide theoretical and practical training to their machine operators. In the event of an incident, the employer must provide qualified proof that they have adequately instructed the machine operator they have assigned. The ZUMBau qualification provides an excellent basis for this.

Note:
The legal requirements for the safe use of work equipment in the machinery sector are described in the German Ordinance on Industrial Safety and Health (BetrSichV). It stipulates that employees must be adequately qualified, trained, and authorized before they are permitted to use work equipment (§ 6 para. 1, § 12 BetrSichV).
TRBS 1116, "Qualification, Training, and Authorization of Employees for the Safe Use of Work Equipment," specifies these requirements and creates legal certainty for construction companies by defining the state of the art. If this technical rule is followed, the employer can assume that the relevant provisions of the German Ordinance on Industrial Safety and Health (BetrSichV) are met (presumption of conformity).

SUVA (Switzerland) and ZUMBau mutually recognize licenses for the "tower crane" machine category.

Upon presentation of a valid SUVA license, a ZUMBau operator's license (plastic card format) can be issued by the accredited examination centre you request. Advanced training/education for tower crane operators provided by SUVA and ZUMBau is mutually recognized.

For the conversion process: The examination centre performing the conversion assigns a registration number (e.g., LWBG_01TK_20170321_00.0111). The SUVA examination date appears in red. Additionally, the entry "SUVA conversion" is recorded in the Federal Central Register under the "Remarks" section.

For the conversion process: The applicant will be charged a fee of € 150 by the accredited examination centre to cover administrative costs. € 100 of this fee covers the examination centre's expenses (coordination with SUVA, issuing/producing the certificate, etc.). € 50 is payable to ZUMBau for registration in the Federal Central Register. All prices are subject to VAT.

To fulfil its tasks, an accreditation committee for examination centres in the German construction industry was established. The sponsoring organizations for the requirements for the examination of machine operators in the German construction industry are the German Construction Confederation (ZDB) and the Federation of the German Construction Industry (HDB).

Another sponsoring organization for the requirements for the examination of demolition excavator operators and long-reach excavator operators is the German Demolition Association (DA).

Further details are regulated in the statutes of the accreditation committee.

Examination centres are accredited by ZUMBau GbR.

For the machine categories of demolition excavators and long-reach excavators, accreditation is also granted by the German Demolition Association (DA).

ZUMBau maintains a list of accredited examination centres for the respective machine types.

Regular audits by auditors appointed by ZUMBau ensure the quality of ZUMBau examination centres.

ZUMBau GbR has developed requirement catalogues for examination centres in each machine category. An initial audit and regular follow-up audits by external auditors appointed by ZUMBau enable accreditation and ensure the quality of ZUMBau examination centres.

The certification process is subject to a fee and requires a successful audit. It is only available to companies that are not construction contractors. Therefore, for quality assurance reasons, testing by the company's own employees is prohibited.

The certification is valid for two years. During this period, at least one audit is typically conducted to further document the quality of the examination centre. If no objection is raised within one month before the certificate expires, it will be renewed for a fee.

The chairperson and deputy are appointed by the accredited examination centre.

The first assessor and deputy are appointed by the ZDB or HDB state association responsible for the respective accredited examination centre, as well as, if applicable, by another sponsoring organization named in the respective association agreement for the construction machinery category.

The second assessor and deputy are appointed by the German Trade Association of the Construction Industry (BG BAU).

The examination committee makes decisions by a majority vote. Minutes of the examination must be prepared and signed by the examiners.
