One man died and another was seriously injured while attempting to cross Queens Drive in Liverpool during major resurfacing works in the summer of 2012.
Enterprise Liverpool Limited and Tarmac Trading Limited were contracted by Liverpool City Council to carry out the works.
Liverpool Crown Court heard how on 3 July 2012 a 74-year-old man suffered head injuries after he was hit by a car while using a crossing at temporary lights.
One side of the Queen’s Drive dual carriageway had been put into a contraflow to allow vehicles to travel in both directions.
But the temporary pedestrian lights were not working and no alternative was provided.
The Court also heard that the following month, 69-year-old Ernest Haughton died after he was hit by a car while attempting to cross a single lane of traffic on the same road using a temporary pedestrian crossing.
Following complaints from motorists, changes were made to the traffic control lights to alleviate congestion but this removed the natural break in traffic flow needed to allow pedestrians to cross the carriageway.
An HSE investigation found that Liverpool City Council failed to ensure that the arrangements for managing the roadworks were suitable, including failing to appoint a suitable co-ordinator for the work.
Instead they had sought to delegate responsibilities to Enterprise Liverpool Limited.
The investigation also found that Enterprise Liverpool Limited failed to ensure the designs for the traffic management were checked or approved, the construction plan for pedestrian routes and provision of barriers was being followed, and at the time of the incidents provided no safe means of pedestrians crossing the works area or the carriageway.
Tarmac Trading Limited who were responsible for the provision and installation of the traffic and pedestrian management failed to provide alternative assistance for pedestrians at the time of the first incident despite it being known that the temporary lights were broken.
When Haughton was killed the temporary lights had been removed but no alternative control measures were put in place to enable pedestrians to cross the live lane of traffic.
In addition a large A-frame sign was placed on the crossing obscuring the view of both pedestrians and motorists.
Liverpool City Council pleaded guilty to breaching CDM regulations and was fined £15,000 and ordered to pay £100,000 costs.
Enterprise Liverpool Limited also pleaded guilty and was fined £25,000 and ordered to pay £80,000 costs.
Tarmac Trading Limited of Solihull, pleaded guilty to breaching the Health and Safety at Work Act, 1974 and were fined £1.3m and ordered to pay £130,000 costs.
Speaking after the case HSE Inspector Jacqueline Western said: “The risks associated with road works are well known in the industry and specific guidance is available to assist with the planning and implementation.
“It is not unreasonable to expect that those who regularly engage in this type of construction work should be well aware of their roles and responsibilities.
“The combined failure of all three dutyholders to comply with their duties on more than one occasion during the Queens Drive resurfacing project, led to one man losing his life and another suffering serious injury. It could quite easily have been two fatal incidents.
“By engaging with the entire project team at the very start of a project, clients like Liverpool City Council, can ensure that a good health and safety culture is embodied throughout the life of the project.
“Ongoing communication and cooperation between the principal contractors and sub-contractors ensures that the project is being adequately planned, managed and monitored.”
