The Institut für Bautechnik (IfBt) is founded in Berlin on 1 July 1968. By way of an agreement, the Federation and the eleven West German Länder assign to the institute the responsibility for granting national technical approvals for construction products as well as other technical tasks in the field of construction.

First seat of the institute
"Bendlerblock" in Berlin-Tiergarten (1968-1995)


In the framework of the transposition of the European Construction Products Directive, Germany designates the institute as the only German technical approval body for European construction products. Thereby, the institute also becomes a member of the European organisation of approval bodies, EOTA (European Organisation for Technical Approvals).



On 1 January 1993 the former East German Länder become parties to the agreement. The institute is renamed Deutsches Institut für Bautechnik (DIBt). Issuing European technical approvals is added to the list of the institute's responsibilities.



In accordance with the Model Building Code, DIBt publishes the Construction Products Lists on behalf of the Länder for the first time.



1995 The institute moves to Kolonnenstraße in



DIBt issues the first European technical approval in Europe.



Having won the approval of the Länder, DIBt becomes a member of the European Union for technical approval (UEAtc).



In its new function as Structural Design Control Authority, DIBt now also grants structural design approvals.



The Länder assign to DIBt a coordinating role in the market surveillance of harmonised construction products in Germany.



DIBt becomes a member of the World Federation of Technical Assessment Organisations (WFTAO).



For the implementation of the new Construction Products Regulation, DIBt is designated as the only Technical Assessment Body in Germany and as notifying authority.



With the entry into force of the revised Energy Saving Ordinance (Energieeinspar­verordnung) DIBt becomes responsible for registering energy performance certificates and inspection reports for air-conditioning systems and carrying out electronic random checks of energy performance certificates.

The European Construction Products Regulation becomes fully effective. As a result, DIBt no longer issues European technical approvals as before, but European Technical Assessments.



The Second Amendment to the DIBt Agreement considerably enlarges DIBt's responsibilities in the field of market surveillance. DIBt now acts as the "Joint Market Surveillance Authority of the Länder".
