OIB Guidelines
The OIB Guidelines serve to harmonise the construction engineering regulations in Austria. They are issued by the Austrian Institute for Construction Engineering upon decision in the General Assembly and are thus available to the federal states. The federal states may declare OIB Guidelines as binding in their building codes.However, the OIB Guidelines may be deviated from in accordance with the provisions of the relevant regulations of the federal states, if it is demonstrated that an equivalent level of protection in compliance with the OIB guidelines is achieved. This is intended to ensure the necessary flexibility for innovative architectural and technical solutions.
The OIB Guidelines follow the concept of performance-oriented building requirements.
The OIB Guidelines are organised according to the basic requirements for construction works of the EU Construction Products Directive. No OIB Guideline exists only for the basic requirement „Sustainable use of natural resources”. There are thus the following OIB Guidelines:
| Guideline | title |
|---|---|
| OIB Guideline 1 | Mechanical resistance and stability |
| OIB Guideline 2 | Safety in case of fire |
| OIB Guideline 2.1 | Safety in case of fire in operational structures |
| OIB Guideline 2.2 | Safety in case of fire in garages, roofed parking spaces and multi-storey car parks |
| OIB Guideline 2.3 | Safety in case of fire in buildings with a fire escape level in excess of 22 m |
| OIB Guideline 3 | Hygiene, health and preservation of the environment |
| OIB Guideline 4 | Safety in use and accessibility |
| OIB Guideline 5 | Protection against noise |
| OIB Guideline 6 | Energy saving and heat insulation |
The OIB Guidelines 2023 were resolved in the General Assembly of the OIB on May 25th 2023 and have not yet entered into force. Until they come into force, the OIB guidelines of April 2019 remain valid. These OIB guidelines 1 to 5 (April 2019 edition) have already entered into force in all federal states, while OIB guideline 6 (April 2019 edition) has currently entered into force in eight federal states.
