Saudi - Negligence caused bridge collapse: Official report

(MENAFN - Arab News) The collapse of the Al-Jamal flyover on the Riyadh-Dammam highway was caused by negligence, a government-appointed technical committee has found



The committee, comprising academics from King Fahad University of Petroleum and Minerals, recently completed its investigation into the incident and sent its report to Minister of Transport Jabara Al-Seraisr



The committee found that due to lack of maintenance, rust and corrosion had set in weakening the concrete structure that collapsed on Dec. 20 but caused no har



The committee had conducted various technical and scientific tests at the site, a source sai



"The committee filed a comprehensive report about the reasons for the collapse with the Ministry of Transport, which ends its role in the investigation," the source sai



"The committee followed routine procedures, starting with a visit to the location, taking samples and analyzing them," the source sai



The source said the investigation showed there was nothing wrong with the design and building of the 30-year-old flyove

The problems had arisen because of the lack of maintenanc



Members of the committee had completed the investigation out of a sense of national duty and not for any financial gain, according to the sourc



The bridge consists of two symmetrical halves, with each side fixed onto a concrete frame in the middl

The collapse occurred on one side close to the supporting frame in the middl

The other side was intac



Othman Subhi Al-Shamrani, assistant professor of civil engineering at the department of architecture and planning at Dammam University, who had examined the bridge earlier, said the collapse might have been caused by water accumulating inside the concrete structure because of a lack of drainage. This may have caused the metal to rust and weaken, he said

Al-Shamrani said members of the engineering faculty who examined the bridge had found rust and corrosion in the iron inside the structure. He said the design had not taken into account the effect of rain, which caused the formation of a thick layer of mud around the structure
