Earthworks / Declaration of Works intents

You are going to carry out earthworks in the public or private domain.

This is a compulsory step, in accordance with the Ministerial Decree 66-009 of 4 January 1966 and the Ministerial Decree 74-292 of 14 June 1974, to allow the executors to know the network layout and the precautions that must be taken due to their presence in the vicinity of the works.

This step must be carried out, at least, 10 working days before the scheduled date of the start of the works. (Public holidays not included)

SMEG’s reply regarding the Déclaration d’Intention de Travaux (Declaration of Works intents) concern the following:


  • 63000 volt high voltage public distribution electrical networks.
  • 20000 volt high voltage public distribution electrical networks.
  • Low voltage public distribution electrical networks.
  • Street lighting electrical networks.
  • Low and medium pressure public distribution gas networks.
  • Heating and air conditioning public distribution networks.

The gas networks operated by GrDf and GRTGaz which transit through the Principality of Monaco.

  • Fill in the form that you can download here and send it to us by post exclusively. A reply and SMEG’S recommendations will be sent by post within 5 working days upon the receipt of your request. (Public holidays not included)

In order to better reply to your request, we recommend giving us the fullest possible information.


Warning: This step may be insufficient, if it is carried out in the works phase and therefore too late to anticipate efficiently any potential issues linked to the networks that SMEG operates. Such an observation may lead, with urgency, to a change in the planned modus operandi, a change in the project plan, supplementary works unforeseen by the construction owner may be necessary.

It’s for this reason that SMEG encourages construction owners to make a request for information prior to the study phase of their projects.
