Project-related approval (ZiE) and project-related construction technique permit (vBG)

If you wish to use a non-regulated construction product for just one building project, you can apply for a project-related approval (ZiE) rather than a national technical approval (abZ). Analogously, a project-related construction technique permit can be granted for a single application of a non-regulated design solution.

DIBt grants project-related approvals (ZiE) and project-related construction technique permits (vBG) for the states of Berlin, and starting 1 January 2026, for Mecklenburg-Western Pomerania and Lower Saxony. The Institute may also grant a waiver for these states.

For decisions related to construction projects in other federal states, please contact the competent supreme building authority (oberste Bauaufsichtsbehörde).

  • §§ 20 and 16a of the Berlin Building Code (BauO Bln)
  • §§ 20 and 16a of the Building Code for Mecklenburg-Western Pomerania (LBauO M-V)
  • §§ 20 and 16a of the Building Code for Lower Saxony (NBauO)

Application from and information sheet (in the German language)

After we have received your application, we will review your documents and request any additional information we may need. You will have the opportunity to discuss any open technical or procedural questions with us.

Once we have received all the necessary information, we will let you know which tests and verifications are needed for your construction product or construction technique. Please commission these services yourself and forward the test results to us when available. If all requirements have been met, we will issue the abZ/aBG for you.

As the name suggests, the project-related approval or construction technique permit only applies to one particular construction project. If the product or construction technique is to be used again, a new application must be submitted. Existing test results and verifications can be recognised if they still reflect the state of the art and are applicable to the new project. Should you need a general verification of fitness for use and/or application under the Building Codes, please apply for a national technical approval (abZ)/general construction technique permit (aBG).

The timeline and fees primarily result from the complexity of the product or the construction technique. Please contact us as early as possible. We will usually indicate the estimated fee for your ZiE/vBG when we confirm your application.
