Further training according to GW 329


DVGW Code of Practice GW 329 specifies the procedure for recognising the required skills and knowledge of the responsible specialist supervisory authority and the specialist personnel for controllable horizontal mud drilling procedures in accordance with DVGW Code of Practice GW 321.

The use of this worksheet ensures that the training and examination of the specialist supervisory authority and personnel is carried out in accordance with uniform procedures and contents, and that the specialist supervisory authority or personnel possesses the necessary specialist knowledge for a quality-assured execution and inspection of the work after having passed the examination. The certification is carried out according to GW 302. The certificate is valid for five years.

During this time, the responsible technical supervisor is required to attend a DVGW-approved training seminar and to have the visit certified in order to maintain its validity. The course teaches developments, techniques and trends of the HDD process as well as refreshing existing knowledge.

In order to maintain the validity of the certificate issued by the technical supervisory authority A/B in accordance with DVGW Code of Practice GW 329, each participant must take part in a training course within the term of the DVGW certificate. This training course meets these requirements.

The seminar is primarily aimed at technical supervisors who have an examination certificate in training levels A and B. In addition, it also serves as a suitable training event for technical personnel, site managers and supervisors working in the field of horizontal mud drilling.


In this context, the DCA organizes in cooperation with the Berufsförderungswerk des Rohrleitungsbauverbandes e. V. (brbv) every year at the beginning of December in Kassel, a further education event according to GW 329.
