Mole ploughing and trenchless pipelaying (S3.7)

Mole ploughing uses a ploughing machine to pull a flexible pipe or cable below ground. It is employed in unmade ground and may be used in verges. The mole plough creates a slit in the surface of the ground which should not require reinstating provided that the surface profile is restored in accordance with S9. However, where connections are made to apparatus installed by mole ploughing, excavations must be carried out and reinstated in accordance with this Code.
Soil displacement moling and other trenchless methods do not create an excavation and, when carried out in a proper manner, do not require reinstatement. However, at launch and receive pits and at any intermediate excavations where connections are made to apparatus, reinstatement must be carried out in accordance with this Code.
Where, as a result of the use of trenchless methods, the authority has reasonable cause to believe that damage may have been caused to the structure of the road, footway, footpath or cycle track, the Investigatory Works Procedure described in the HAUC Code of Practice for Inspections should be commenced as if the defect was associated with a reinstatement defect for the purposes of that Code.
Any remedial work agreed between the authority and the undertaker to be necessary must be carried out in accordance with this Code and at the undertaker’s expense if carried out by the undertaker. If the agreed remedial work is carried out by the authority at the undertaker’s expense, the provisions of this Code do not apply.
In the absence of agreement between the authority and the undertaker, liability for any damage must be determined in accordance with section 82 of the Act (liability for any damage or loss caused).
