Expert witness says Murray & Roberts could not have predicted M1 bridge collapse

The inquiry into the Grayston Bridge collapse has resumed and Professor Roelof Mostert has testified as the first expert witness from the construction company Murray & Roberts.

In 2015, two people died and 19 others were injured when scaffolding collapsed on the M1 highway, trapping several vehicles.

Mostert says he observed a number of failures in the connection of the bridge beams following the accident, reports EWN's Thando Kubheka.

Mostert, an expert in metallurgical engineering, has analysed the materials that were use to build the bridge structure and presented visual evidence.

According to Mostert, Murray & Roberts could not have predicted the bridge collapse.

He says unexpected pressure to the structure may have caused the failure of the construction materials.

Three additional experts are expected to give evidence, Kubheka explains.
