Construction products detail

Wall construction techniques comprising lattice girders, sandwich anchors or shuttering systems

For these wall construction techniques, precast concrete elements fitted with reinforcement are filled with in situ concrete.

For applications comprising precast elements, lattice girders may be used to resist the formwork pressure and to increase the shear resistance. 

Regulatory framework

In some cases, there are no conclusive technical rules for the design and execution of the construction techniques described above. DIBt therefore grants general construction technique permits (aBG) for these application upon request.

National technical approvals (abZ) can be granted for individual components/reinforcing elements/hollow bodies if they significantly deviate from the applicable Technical Building Rules (cf. MVV TB, Part C) or the harmonised standards.

European Technical Assessments (ETAs) can also be issued for construction products which are not (fully) covered by a harmonised standard.

The following documents are not published, but are made available to concerned stakeholders:
External surveillance guidelines for lattice girders (Richtlinie zur Überwachung von Gitterträgern)

Approval principles for lattice girders (Zulassungsgrundsätze für Gitterträger)

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).

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.
