ENGIE helps to rejuvenate the Léopold II tunnel
At a little over 30 years old, the Léopold II tunnel, the longest and most complex tunnel in Brussels, is showing signs of old age. Its leak tightness, roads and electromechanical components must be renovated immediately. Work will begin in early May. ENGIE Fabricom will help to give the tunnel a new lease of life.
The Léopold II tunnel is used on a daily basis in both directions by 40,000 Brussels residents and commuters. However, this 2.5-km-long tunnel, which connects the Basilica and Brussels’ inner ring road, has gone through a lot since it was built in 1986. Given the urgency, the tunnel needs to be completely remodelled to ensure the safety of those using it.
800 km of cables and over 200 cameras
On January 24, the authorities of the Brussels-Capital Region announced that renovation work would begin in May 2018. This work has been entrusted to the consortium Circul 2020, which includes ENGIE Fabricom, an ENGIE Services entity. ENGIE Fabricom will be supported throughout the project by Besix and Jan De Nul, which will deal with the civil engineering side.
To rejuvenate the Léopold II tunnel, ENGIE Fabricom will lay over 800 km of cables to supply it with electricity. It will also modernise and improve fire safety as well as installing an alarm for emergencies and over 200 cameras!
These cameras, which will be installed, managed and monitored by ENGIE Fabricom, will serve different purposes. Some will be used to monitor the tunnel, others will manage the flow of traffic or check vehicles in this low-emission zone. A fibre optic communication network will be used to transmit high resolution images and radio communications.
Looking to the electromagnetic aspect of the project, the ENGIE subsidiary will also install LED lighting within and at the entrances to the tunnel, as well as at the emergency exits (17 of which are new) with a view to reducing the infrastructure’s electricity consumption by two thirds. Dynamic signage will also be installed.
A precursor to the city of tomorrow
All of the solutions soon to be deployed in the Léopold II tunnel are technologies designed and developed by ENGIE to prepare the city of tomorrow and make it safer, more efficient, more connected and more sustainable.
Work on the Léopold II tunnel will be accompanied by measures intended to minimise the impact on traffic and local residents. As such, the tunnel will only be completely closed to traffic in July and August and during the night from Sundays up to and including Thursdays. For the rest of the year the tunnel will remain open to traffic during the day and on Friday and Saturday nights.
Once work is complete, ENGIE Fabricom will take charge of maintaining the tunnel for the next 25 years.
