Wagenborg installs connective trusses Pontsteiger

Wagenborg transported and installed 4 enormous steel trusses as part of the construction of the Pontsteiger in Amsterdam. These trusses, built by Buiting Staalbouw in Almelo, connect the Pontsteiger’s two luxurious residential towers.

June 2017, the pinnacle of an intense preparation period: after being shipped over land and water by Wagenborg from Almelo to Amsterdam, the steel trusses were installed. Sadly the installation of the first truss had to be delayed because of the stormy winds. A setback for both those involved and interested, including the residents of the Silodam. On June 9 the time had finally come and Wagenborg was able to install the first truss.

To install the trusses (with a length up to 48.5 metre and weighing up to 78 tonnes each), Wagenborg deployed two mobile telescopic cranes equipped with a jib, each with a lifting capacity of 500 tonnes. The Pontsteiger is situated on the river IJ, a beautiful but very cramped jobsite. Both cranes had to be positioned between the structure itself and the sheet piling. Not a problem for Wagenborg, but above all an interesting challenge. In close cooperation with all parties involved, Wagenborg installed the trusses according to plan. In the end it all came down to craftsmanship and cooperation between the crane operators, seeing there was only a few millimetres leeway!

Upon delivery, the Pontsteiger will be one of the biggest and highest residential buildings in Amsterdam. The Pontsteiger was designed by Architectural firm Arons & Gelauff: a true eyecatcher of the city’s skyline, with a view over the river IJ and the Houthaven port.
