How Hendriks' formwork is meeting the challenge.
Hendriks' innovative tunnel formwork was chosen for the construction of the Rottermerentunnel (part of the new connection between the A16 motorway at Terbergseplein and the A13 motorway at Rotterdam The Hague Airport).
The challenge in constructing the 2,235-metre-long tunnel lay in connecting the walls to the tunnel floor. The floor is not flat due to the use of underwater concrete. The planning also presented challenges. The tunnel with a central tunnel channel had to be poured in 25-metre sections in a weekly cycle. With two sets of formwork, 90 pours are required, with the last pour still achieving surface assessment class B1.
The team at Hendriks found a solution in formwork that provides an optimal connection with a hydraulic crawler. The system is now in use and produces impressive images.
