Building and dismantling an overhead line
Throughout all its projects, Elia ensures that it takes all necessary measures to limit the work’s impact, preserve the environment and maintain residents’ quality of life.
Stages of work
The work involved in building and dismantling an overhead line is conducted in two separate phases to ensure that the power supply is maintained and the grid remains reliable. To this end, the new line must be commissioned before the old one can be taken down.
Phase 1: Building the new line
Phase 2: Dismantling the current line
Organisation of the work
Respect for local residents and the environment is a priority for Elia. While every project is different and very much depends on the type of infrastructure involved, Elia always organises its work in collaboration with all relevant parties (including the contractor, the local authorities, the local police and landowners) and regularly updates local residents on the progress being made.
While work is ongoing, Elia implements a series of measures focused on three key areas: safety, noise control and mobility management.
- Noisy work is carried out during working hours, unless otherwise agreed with the relevant authorities with a view to reducing the impact on mobility at specific times.
- Site vehicles only leave their engines running when necessary.
- Work areas are always marked out clearly and a site safety coordinator is always on hand to ensure that activities on the site run smoothly.
- Furthermore, site meetings are held with contractors to discuss points for attention (e.g. itinerary, waste sorting).
- When the existing line is being dismantled, safety gantries are put in place while the power cables are pulled to protect infrastructure along the route (roads and homes).
- If the work requires temporary road closures, appropriate diversions and signs are put in place in consultation with the local police.
- Work-in-progress signs are erected in dialogue with the local police. These signs provide residents with all the information they need (in particular, the start and end dates for the work).
- Elia strives to ensure that local residents always have access to their homes.
