Engineer of Laval overpass says his design was not followed

The engineer who originally designed the overpass in Laval, Quebec that collapsed last September has testified that his plans were not followed.
At the inquiry into the collapse, Gilles Dupaul said that from photographs he had seen of the structure since it fell, the reinforcing steel bars seemed to be too short and too few. The steel contractor is now defunct.
The 78-year old engineer said he did not visit the site during construction, which took place more than 35 years ago.
The overpass near Montreal collapsed in September and killed five people.
Quebec’s Transport Ministry has said it will not demolish 15 highway overpasses that are of a similar design to the Concorde structure that collapsed. However, the province dos plan to reinforce them over the next five years. They are in Montreal, on the North Shore, the Laurentians, Monteregie and Central Quebec.
