Vision Documents for Trenchless Technique Codes





Trenchless Technology is the family of Techniques to develop and maintain the subsurface networks through a non destructive way if engineered properly. If not, techniques can lead to substantial destruction as a substantial portion of work is done below the ground. In order to contain this destruction to the lowest possible levels a set of directives defining the ways to work (codes of practice) for a particular technique is required. Further, Trenchless Techniques are being developed internationally and their localization to suit the ground requirements is also necessary. Proper promotion of Trenchless is only possible if such Codes of Practice are defined.




IndSTT, with a view to this has initiated process to establish Codes of Practice for various Trenchless Techniques and other related activities. The draft documents detailing Special conditions and the Inspection Guidelines for the following techniques have already been developed:

  1. Horizontal Auger Boring (HAB), and;

  2. Pipe Ramming (PR).

Vision Documents


In addition vision documents for operational works detailing the following issues have already been developed:


  1. Code of Practice for Safety at Road & Highway construction works;

  2. Code of Practice for Reinstatement of Openings at Roads & Highways;

  3. Code of Practice for Recording of Underground Utility Networks & Services.

Working Group to Develop Codes of Practice Suiting Indian Condition


Presently IndSTT has established a working group to develop standards and specifications for Trenchless Techniques suiting Indian requirements. To know more about this Working Group please Click Here.
