Faulty suspenders gave way

Was it faulty components that did the pedestrian bridge in?
According to highly-placed sources in the government, the committee looking into reasons behind the collapse of an under-construction bridge near Jawaharlal Nehru Stadium has found serious problems with the steel suspenders, its connectors and pins to which the 85-metre deck was hanging.
The pedestrian bridge, known as 'rainbow bridge' for its design, broke into three pieces and collapsed on Tuesday afternoon. Twenty-seven construction workers, working on the bridge and close to it, were injured.
After the accident, PWD’s engineer-in-chief Rakesh Mishra had said the pin that connected one of the 26 suspension bars with the bridge had first snapped.
Sources said the inquiry committee has found problems with Macalloy tie bars (steel suspenders) and other parts that held the deck with the arch. The tie bars and its connectors have been imported from a UK-based company called Macalloy bar and cable systems.
Glasgow Clyde Arc Bridge, which was built on River Clyde in Glasgow, Scotland, had similar problem.
The same company, which supplied the steel bars for the pedestrian bridge in Delhi, had supplied to the agency that had built the Glasgow bridge.
“The problem is that Macalloy does not have a contact person in India,” a senior PWD official said requesting anonymity. The government has constituted a two-member inquiry committee to look into the matter.
