Brussels Airport is planning major renovation works on runway 01/19 from 26 July to 25 September 2016. To minimise their duration and their impact on neighbouring residents and airport activities, the renovation works will be carried out in stages, including at night.
The runways at Brussels Airport have to be thoroughly renovated every 30 years so that all aircraft movements can continue safely. Last summer, runway 07R/25L was thoroughly renovated; this year, it is cross runway 01/19. The asphalt surface layers will be removed and replaced, the runway shoulders and drainage system will be renewed, the sewerage will be renovated and the runway lighting will be replaced by energy-efficient LED lighting.
The works are scheduled from 26 July to 25 September because the summer months provide the most favourable weather conditions and this reduces the risk of delays on site. During the first month of the renovations, work will continue 24/7; in the second month, works will only be carried out between 10 pm and 6 am. However, work may be delayed due to unexpected technical setbacks or unfavourable weather conditions.
During the works, runway 01/19 will be mostly unavailable. Therefore, runway use during the renovations will deviate from the preferential runway system at certain times. The flight paths themselves will not change during the works; work will only impact the frequency with which they are used.
What will change in comparison with the preferential runway system?
According to the preferential runway system (PRS), runway 01/19 is used at four periods of time. As runway 01/19 will not be available during most of the works, a different runway system will be put in place. The table below shows what will change in those four periods of time due to the renovations on runway 01/19.
At these four times, landing aircraft will use runway 25 Left or 25 Right.
During unfavourable wind conditions
If there is a strong northerly or easterly wind, runway 07 Right or 07 Left will be used for take-offs, as is also the case when no works are being carried out. For landings, runway 07 Left will principally be used during the works. In this case, aircraft will use a flight route over the north of Brussels.
26 July to 7 August: Southern and central section, zone 1
The first stage of renovations on runway 01/19 will start on 26 July with the reconstruction of the southern and central section of the runway, together with zone 1 as indicated on the map. The asphalt will be scraped off and replaced, and the channel gratings removed and renewed. The sewers will be renovated using sleeving technology, via which a resin impregnated sleeve is placed in the original pipe and cures on the inside. Also, the installation of LED lighting on the runways will begin.
During this stage of the renovations, the other two runways (07L/25R and 07R/25L) will remain operational. Take-offs will use runway 25R, while incoming flights will land on runways 25 Right and 25 Left. When windy conditions prevent the use of this runway system from being applied, flights will take off from 07 Left and 07 Right, and mostly land on runway 07 Left.
In the nights of 2 to 4 August, works will be carried out on the intersection with runway 07R/25L. For these three nights this runway will not be available and all traffic will use runway 07L/25R.
7 August to 19 August: Southern and central section, intersection with 25 Right and zone 2
The second stage of the works begins on 7 August and will last 12 days. During this time, work on the southern and central sections of runway 01/19 will continue, and will begin on the intersection with runway 25 Right and zone 2. The asphalt will be scraped off and replaced, and the channel gratings removed and renewed. The renovation of the sewers and installation of the LED lighting will continue.
During this stage of the renovations, runway 01/19 will not be in use, and runway 07L/25R will only be partially available. All take-offs will be from runway 25 Right. At this stage, all incoming flights will land on runway 25 Left.
When windy conditions prevent the use of this runway system from being applied, all flights will take off from runway 07 Right, and all incoming flights will land on the shortened runway 07 Left or exceptionally on runway 07 Right.
19 August to 26 August: Southern and central section 24/7, intersection with 25 Right and zone 2 between 10 pm and 6 am
The third stage of the works will take one week and will start on 19 August. During this period, work on the southern section of runway 01/19 will be completed and work will continue on the central section. Work will continue at night on the intersection with runway 07L/25R and zone 2 will be closed to traffic. During this stage, the replacement of the asphalt, the renewal of the channel gratings, and the renovation of the sewers and the lighting will continue. A new sewage pipe will be installed at the intersection with runway 25 Right. Where possible, grooves will already be cut in the asphalt of runway 01/19.
During this week, all flights between 6 am and 10 pm will take off from runway 25 Right and land on runways 25 Right or 25 Left. If windy conditions prevent this runway system from being applied, all flights will take off from runways 07 Left and 07 Right, and land mostly on runway 07 Left.
Since in this stage works will be carried out between 10 pm and 6 am on the intersection between 01/19 and 25 Right, the available runway length of runway 07L/25R will be reduced during these hours. When there is a south-westerly wind, all flights will take off from 25 Right and land on 25 Left. When there is a north-easterly wind, all flights will land on 07 Left (or exceptionally on runway 07 Right) and take off from 07 Right.
26 August to 25 September: Central section, zones 1 and 2
The final stage of the works begins on 26 August and will last until 25 September. During this stage, the central section, and zones 1 and 2 will be completed. In this stage, works will only be carried out at night which means that runway 01/19 will be available during the day. Works in this stage include the completion of the grooving in the asphalt and the LED lighting.
In the final stage of the works, all flights will take off from runway 25 Right, while incoming flights will land on runways 25 Right and 25 Left. If windy conditions prevent this runway system from being applied, daytime flights will take off from runway 07 Left, 07 Right, 01 or 19, and night flights from runway 07 Left and 07 Right.
Incoming daytime flights will land on runway 07 Left, 01 or 19; and night flights on runway 07 Left or exceptionally on runway 07 Right.
