The PDA are based on the specialised data catalogue (FDK) and the regulations for building models. They are a mandatory requirement for the creation of discipline-specific models and are therefore part of the contract.
The project-specific data requirements determine which project participants must create which discipline-specific models for which facilities, containing which information, during which project phase. They also specify which object types and properties must be included in the discipline-specific models.
The PDA are an important part of the Exchange Information Requirements (EIR). They include both the Asset Information Requirements (AIR) and the Project Information Requirements (PIR).
SBB provides the PDA in both Excel format and as machine-readable IDS files. This enables contractors to import the PDA into various applications. SBB also uses the PDA to verify the data quality of the discipline-specific models.
