Construction products detail

Other tendons

Other tendons include special prestressing components, e.g. for realising innovative construction techniques based using prestressing systems, also in combination with other manufacturing and reinforcement techniques.

Regulatory framework

DIBt grants national technical approvals (abZ) for innovative prestressing systems for which no Technical Building Rules and no generally recognised technical rules exist.

For innovative construction techniques based on prestressing systems for which there are no conclusive technical rules, a construction technique permit (aBG) is usually required in cases which are relevant from a regulatory point of view. DIBt grants general construction technique permits upon request.

European Technical Assessments (ETAs) can also be issued for prestressing kits.

We are happy to advise you.

National procedure

A national technical approval (abZ) and/or oder general construction technique permit (aBG) is granted upon application (see Model Building Code (MBO), Sections 16a(2) and18(2) and (4)). This also applies to amendments and supplements to, or renewals of existing approvals and/or construction technique permits.

No formal requirements apply. The following information is needed: name and address of the applicant, description of the product and/or construction technique and its field of use or application, type of decision required (new decision, amendment or supplement to, or renewal of, an existing decision).

Please feel free to use the template below.

European Technical Assessment (ETA)

To start the ETA procedure, please submit the form below. We will then check if the prerequisites for issuing an ETA are met, i.e., in particular, if the product is not fully covered by an existing harmonised standard. If the prerequisites are met, we will check whether a European Assessment Document (EAD) covering the requested assessment scope already exists or still needs to be developed. If an EAD needs to be developed or amended, a complete technical file needs to be established before the procedure can begin.
