Clear guidelines for construction projects
The OIB Guidelines are a central component of construction engineering regulations in Austria. They serve to harmonize the technical construction requirements of the federal states and form the basis for legally compliant and uniform enforcement. The aim is to clearly define the requirements for the safety, energy efficiency and usability of buildings.
Every four years, the OIB Guidelines are developed and adapted by the Austrian Institute of Construction Engineering together with experts from the federal states and numerous stakeholders from the construction industry and business. Following a decision by the General Assembly, they are published and then made available to the federal states. These can declare the OIB Guidelines binding, for example by means of a building technology ordinance. This ensures uniform implementation in Austria.
TO enable maximum flexibility and technical innovation despite strict criteria, it is possible to deviate from the OIB Guidelines in accordance with the provisions in the relevant ordinances of the federal states if it can be demonstrated that an equivalent level of protection is achieved as if the OIB Guidelines were complied with.

OIB guidelines
The OIB Guidelines are based on the basic requirements for construction works of the Construction Products Regulation (EU CPR) and cover topics such as fire protection, sound insulation, energy saving and accessibility. In addition, a new OIB Guideline on the sustainable use of natural resources (OIB Guideline 7) is currently under development.
The OIB Guidelines 1-6 are divided into the following areas of construction:
| OIB Guideline | Title |
| OIB Guidelines 1 | Mechanical strength and stability |
| OIB Guidelines 2 | Fire protection |
| OIB Guidelines 2.1 | Fire protection for commercial buildings |
| OIB Guidelines 2.2 | Fire protection for garages, covered parking spaces and parking decks |
| OIB Guidelines 2.3 | Fire protection for buildings with an escape level of more than 22 m |
| OIB Guidelines 3 | Hygiene, health and environmental protection |
| OIB Guidelines 4 | Safety of use and accessibility |
| OIB Guidelines 5 | Sound insulation |
| OIB Guidelines 6 | Energy saving and thermal insulation |
