Basics
The DWA worksheets and information sheets (DWA-A and DWA-M) are intended as a thematically related family. In our calculation programmes, we refer to these publications, among others:
- DWA-A 127-1 - Structural analysis of drainage systems - Part 1: Fundamentals
- DWA-A 127-10 - Structural analysis of drainage systems - Part 10: Material properties
With a licence for e.g. the A127 trench installation calculation module, you indirectly use the contents of the above-mentioned regulations. Furthermore, numerous material-specific standards are integrated through cross-references, for example EuroCode 2-1-1 and EC3, or EC 1-2 as a basis for traffic loads.
