Since its foundation in 1994, the Drilling Contractors Association DCA (Verband Güteschutz Horizontalbohrungen e.V.) has been releasing numerous publications written by its members. These have made a contribution to a steadily growing acceptance of the HDD method among clients, authorities and planners.

The centrepiece is the Technical Guidelines of the DCA, known to the industry under the title “Information and recommendations for planning, constructing and documenting HDD projects”.  It is available as 4th edition from 2015 in three languages.

Other publications about issues like quality management, general terms and conditions or bills of quantities can be obtained from the office like the technical guidelines - also by non-members.

DCA’s Newsletter, conceived of as periodical for DCA’s members, offers basic information for members about topical issues of the association, events etc. But it is primarily a forum to present the own company within the association.
