Ayr Sherriff Court heard that, on 20 February 2018, W & E Lammie was carrying out drainage works at a site in Cumnock when a section of the unsupported wall of the excavation collapsed and crushed one of its employees causing serious injuries.

An HSE investigation identified that W & E Lammie failed to plan the precautions or practicable steps necessary to prevent danger to any person entering the excavation, failed to provide supports or battering to ensure the excavation did not collapse and failed to provide appropriate training and supervision to the employees carrying out the drainage works.

The investigation also identified that in their role as principal contractor, Auberne Homes Limited, failed to plan, manage and monitor the drainage works being carried out on their construction project.

W & E Lammie, a now dissolved partnership, previously of Cumnock pleaded guilty to breaching CDM regulations and were fined £18,000.

Auberne Homes Limited of Ayr also pleaded guilty to breaching CDM regulations and were fined £35,000.

Speaking after the hearing, HSE inspector Duncan Officer said: “This incident could so easily have been avoided had the excavation work been properly planned and carried out by suitably trained individuals to ensure that the appropriate safety measures were implemented to prevent excavation collapse.

“Had the principal contractor carried out suitable checks they could have been identified that those carrying out the work were untrained and that safe working practices were not being followed on site.

“The requirement for control measures and safe working practices during excavation work are well-known in the construction industry.

“HSE will not hesitate to take appropriate enforcement action against those responsible for the excavation works and those in control of the construction site where these required standards are not met.”
