Bouygues fined £175,000 for concrete beam death
The contractor was also ordered to pay ��80,000 in costs after Guilherme de Oliveira, 44, from Portugal, was crushed to death at Broomfield Hospital in Chelmsford on November 10 2008.
Chelmsford Crown Court heard that Mr de Oliveira was working for Bouygues through an agency as a banksman, and was fixing beams across supporting towers to form part of the concrete structure for a new building.
The beams were lifted from ground level to the work area by a tower crane.
The beam was lifted into position, but the weather on the day was worsening with increasing wind speeds.
Before Mr de Oliviera was able to disconnect the chains on the beam at his side, the wind gusted at such a speed that it exceeded the safe working parameters of the used tower cranes.
Mr de Oliveira and another banksman climbed the support towers to unhook the lifting chains from the concrete beam �C which was seven metres in length and was due to sit almost three metres off the ground.
As a result, the slew brakes slipped and the crane moved with the wind.
An HSE investigation found that four tower cranes were in operation at the site, each one fitted with a sensor that measured wind speed and provided warnings at pre-set values: an amber warning at 50 km/h or more and a red warning at 72km/h or more.
The sudden movement caused the crane to swing round with the beam, which caught Mr de Oliveira and crushed him between the beam and an adjacent tower. The wind speed at that time was in excess of 72km/h.
The sensors were linked to a computer in the site office to allow managers to monitor data and supervise lifting operations.
But at the time of the incident it was not being monitored and on-site arrangements allowed used tower cranes operators to check their own wind speed displays. So they would only have stopped lifting if they considered it necessary, and not necessarily when the maximum wind speed limit was exceeded.
HSE concluded that there was inadequate planning and supervision of the work.
Had a suitable management procedure been in place and followed there would have been the opportunity to properly consider the deteriorating weather conditions and then take the tower cranes out of operation.
Bouygues UK Ltd, of London, SE1 was fined ��175,000 and ordered to pay ��80,000 in costs after pleading guilty to breaching lifting regulations.
Bouygues said: ��We sincerely regret that this tragic accident, which resulted in an individual losing his life, should have occurred on one of our sites.
��Our thoughts and deepest sympathies are with the family and friends of Mr de Oliveira.
��The safety and welfare of our staff and of those that work with us through our supply chain is top priority at Bouygues UK.
Speaking after the hearing HSE Inspector Dominic Elliss, said: ��Although the judge was not satisfied that the company��s failings was a direct cause for Mr de Oliveira��s death, he said there was a systemic failure where a risk of serious injury was foreseeable.��
��We are focussed on learning lessons from the past and continually assessing, improving and embedding health and safety practices and behaviours across our business so that people go home safely.��
��Lifting operations can be highly hazardous and the appropriate standards are clearly set out in both the regulations and industry guidance.
��There is no excuse to ignore them and I would urge all those undertaking such work to review the effectiveness of their own controls to ensure safety on construction sites.
