Expertise for the Yang Pu Bridge - Shanghai on behalf of the Asian Development Bank
In 1992 the construction of the superstructure of the Yang Pu Cable-Stayed Bridge in Shanghai started. At that time the span width of 602 meter was a world record. The bridge was supposed to be financed by the Asian Development Bank (ADB). As a condition for granting the credit the ADB appointed an international committee of experts for cable-stayed bridges to examine the construction design, the calculations of the manufacturing and the construction of the Yang Pu Bridge.
Members of the commitee were one American and one Japanese expert as well as our Director Dipl.-Ing. Holger S. Svensson, P.E., PEng., CEng MICE, FIStructE, MHKIE.
The commitee was informed by the chinese
engineers and other experts of construction and manufacturing.
They held a meeting at a chinese-american engineers office in New York which presented the preliminary survey.
Later the members of the commitee went to Shanghai for two weeks in order to perform examinations locally. At that time the bridge girder was already under construction (pic 2).
The manufacturing of the steel superstructure and the cables (typ HiAm) have been examined.

The actual construction of the superstructure has been examined on site (pic 3).
After all the commitee confirmed that the design and construction of the Yang Pu Bridge is in accordance with the international state-of-the-art. On August 17th 1992 the final report was finished and handed over to the city council of Shanghai as the principal and to the Asian Development Bank as financier.
The construction of the bridge was completed on October 23rd 1993 and opened for public traffic (pic 5).
