In the years since the adoption of the statement until now existing, there has been a fact of great importance in the structures concerning regulatory landscape: the drafting of the structural Eurocodes and their gradual adoption by various European countries as technical codes for the bridges project. The scope of the IAP is entirely contained within the scope of the EUROCODE 0, Bases of calculation, and the EUROCODE 1 actions on structures. Adaptation of the contents of the IAP to these two European standards is that, fundamentally, has inspired the drafting of the text of the IAP-11 instruction.
On the other hand, the evolution of the national regulatory framework in the field of structures, both in different facets which may be subject to regulations (bases of projects, actions, calculation, execution or quality) and in the various fields of application (building, railway and road), has guided update looking for greatest possible coherence in this regulatory context.
