BRIDGE AT GERUSALEM

LIGHT RAIL TRAIN BRIDGE AT GERUSALEM – CALATRAVA PROJECT (MARCH-APRIL 2008)

The bridge designed by the architect Calatrava which houses two light rail tracks and a pedestrian crossing is the new entrance to the city as well as the symbol of the urban renewal of Jerusalem.

The imposing C-shaped structure to follow the curve that connects Jaffa Road to Herzi Boulevard is supported by 66 steel cables anchored to a single 118 meters high inclined pylon that rises in the middle of the C.

The welds, which connect the inclined pylon to the horizontal base structure, whose thickness varies from 150 mm to 200 mm, obviously have a significant importance in the context of the structure.

In March and April 2008 Tecnocontrol on behalf of the company CIMOLAI S.p.A. performed the Ultrasonic Test of these important welds during their realization by the local specialized personnel.

The control, previously planned and approved by IIS (Italian Institute of Welding – Genova Italy), was performed using conventional manual ultrasound techniques and with advanced TOFD ultrasonic technique.

During the various stages of the ultrasonic examination, the results were continuously assessed together with the Israeli Works Direction, which showed from the first day, appreciation for our work during the entire period of presence at the site.
