Different steps of a working site

Preparing the working area

Working area: 15 to 36 metres

Depending on the diameter of the pipeline, an area of 15 to 36 metres wide must be cleared.

  • The working area is marked out on either side.
  • Temporary fencing is erected wherever necessary.
  • We temporarily remove any existing obstacles, plant life or crops.
  • It is sometimes necessary to place temporary mechanical covering over ditches.
  • When required, we divert drainage systems during the works.
  • Layers of sand may be spread to facilitate transport.

Tips for using search operators

Use "quotation marks" to search for a series of words or a phrase in a specific order.

Boolean operators

You can find a group of words or a phrase by using the link words AND, OR and NOT:
known as Boolean operators, these words are used to combine terms in the search field.

  • AND: All the search terms must be included in the publication. Typing in Apple AND Pear will return publications containing both the word Apple and the word Pear.

     

  • OR :  At least one of the search terms must be included in the publication. Typing in Apple OR Pear will return publications containing either the word Apple or the word Pear or both.

     

  • NOT: The term preceded by NOT must not be included in the publication. Typing in Apple NOT Pear will return publications containing the word Apple but not the word Pear.
