Application for public appointment as an expert in the architectural and construction industry

Applicants for public appointment and swearing-in must prove their personal and professional suitability in a specific subject area (e.g. damage to buildings) as part of a strict examination procedure. Experts are commissioned by private individuals, public authorities and, in particular, by courts to provide technical bases and expert opinions. Despite being commissioned by a specific person, the expert is not a lobbyist. He or she is obliged to perform his/her task independently and on his or her own responsibility. In addition to the special expertise, special requirements are therefore also placed on the personality and reliability of the expert.

Courts are obliged to commission publicly appointed experts as a matter of priority to prepare expert opinions.

Process flow

An application for a public appointment must be submitted in writing or online using the form provided. The above-mentioned evidence must be attached to the application.

The examination of the special expertise and the ability to prepare expert opinions is carried out by a panel of experts.

The expert committee examines the expert opinions submitted. Furthermore, the special expertise must usually be proven by a written exam and an oral examination.

The Board of Directors of the Chamber decides on the public appointment on the proposal of the Committee of Experts.

The initial appointment is limited to three years. Subsequently, there is the possibility of extending the appointment by five years at a time.

Who should I contact?

The responsibility lies with the Lower Saxony Chamber of Architects.

This procedure can also be handled by a "Point of Single Contact". The "Point of Single Contact" is a special service offered by the municipalities and the state for service providers.

Personal injury must be insured at least €1,500,000, property damage and financial loss at least €200,000 per insured event. The insurer's benefits for all damage caused within an insurance year may be limited to twice the amounts previously mentioned. The insurance must be maintained for the duration of the order. Anyone who does not exercise the profession for personal reasons, in particular due to illness or parental leave, shall be exempted from the obligation upon written request.
