The select method of construction combines the intensive use of precast concrete element and prestressing with Freyssinet cables and Macalloy bars. These precast element are : piles, head of piles, hyperstatic and isostatic beams and deck plates. After the realization of the foundations, a foundation unit is cast in place.
Inclined precast piles are installed by crane and then heads units. These sets are post-tensioning cables : 16 cables 19C15 per set.
Between these sets, U shape precast beams are installed. Some of them will be made hyperstatic. On the 2 main beams, precast deck slabs will be bonded by cables 13C15.
In total, 1.200 tons of cables and 650 bars will be delivered and installed by Freyssinet Belgium.
