Prestressed precast slab/in situ concrete systems

These floor systems are composed of prestressed precast slabs finished with a structurally contributing in situ concrete overlay.

Regulatory framework

DIBt grants national technical approvals (abZ) for precast slab/in situ concrete systems which are not (fully) covered by DIN EN 13747.

European Technical Assessments (ETAs) can also be issued for precast slab/in situ concrete systems which are not (fully) covered by DIN EN 13747.

If there are no conclusive technical rules for the design and application of the precast slab/in situ concrete system, a general construction technique permit (aBG) may need to be taken into consideration.

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).
