the basic requirements for buildings

A 1 Mechanical strength and stability

A 1.1 General information

Under § 3 and § 12(1) of the MBO1 each building structure must be stable as a whole, in its individual parts and on its own. The stability of other structural works and the bearing capacity of the building site of neighbouring plots may not be jeopardised. Furthermore, any effects arising during erection and use must not cause damage to any parts of the structure or facilities and equipment due to excessive deformations of the load-bearing construction.

To meet these requirements for building works, the Technical Rules under Section A 1.2 must be observed.

A 1.2 Technical requirements in respect of the planning, designing and execution of structural works and parts thereof pursuant to § 85a(2) MBO1

Preliminary remarks
1 Building regulations requirements
The Model Building Code (MBO)2,,3 contains in § 85a(1) the authorisation to specify, within the framework of an
administrative provision, the general requirements for structural installations, construction products and other
systems and installations through Technical Building Regulations.
Article 85a(2) MBO1 lays down detailed specifications as to which building inspection requirements can be
elaborated in detail. The specifications may take the form of references to technical rules and their sources or in
other ways, in particular in relation to:
n the design, dimensioning and execution of structures and their parts;
n The characteristics and performance of construction products in particular structures or their parts,
n procedures for determining the performance of a construction product which does not bear the CE mark
pursuant to the Construction Products Regulation,
n Permissible and prohibited special uses for construction products,
n Definitions of classes and levels that construction products are required to satisfy for specific uses,
n Requirements for issuing the declaration of conformity for non-harmonised products,
n information on non-harmonised construction products and types requiring a general inspection certificate; and
n type, content and form of the technical documentation.
The basic principle is that only those provisions are included in the Model Administrative Order laying down
Technical Building Regulations (MVV TB) as Technical Building Regulations that are essential for fulfilling the
