Technical Guidelines
To ensure high quality standards in the implementation of HDD projects, the DCA has published technical guidelines, which are currently available in their 5th edition in German and English.. A fifth edition of the French version is currently in preparation.
The DCA Technical Guidelines represent the association’s standard work on HDD technology.

The standard work on HDD technology is widely recognised in Europe and is used by clients and contractors alike for the planning and implementation of HDD projects.
The German version of the guideline has also been mentioned by name in Germany in the so called „Verdingungsordnung für Bauleistungen (VOB) in the course of the introduction of a separate DIN standard for HDD drilling.
The following main topics are dealt with in the technical guidelines:
- Project basics
