Construction products detail

Other concrete construction techniques

Other concrete construction techniques include, e.g., knife-edge bearings and ring beams.

A knife-edge bearing is used to introduce vertical and horizontal forces into sheet piling profiles and steel tubes. It is used for direct force transmission from the reinforced concrete head beam into the sheet piling profiles or from the concrete superstructure into vertical steel tubes without any need for load-distributing structural elements.

Ring beams with the associated formwork are used to manufacture structurally required ring beams or lintels for resisting vertical and horizontal loads.

Regulatory framework

Numerous concrete construction techniques that are relevant from a regulatory point of view and for which there are no conclusive technical rules are used in structural engineering. DIBt grants general construction technique permits (aBG) for the design and execution of these concrete construction techniques.

If individual construction products used in the assembly

  • significantly deviate from the Technical Building Rules (cf., in particular, MVV TB, Part C) or
  • no Technical Buildings Rules nor generally recognised technical rules exist for these products,

DIBt can grant national technical approvals (abZ) for them.

European Technical Assessments (ETAs) can also be issued for concrete construction products.

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.
