A construction company has been fined after an employee was killed when a partially built wall collapsed at a school site in UK. The incident highlighted the devastating consequences of failing to properly plan and supervise temporary works in construction.
The Incident
In March 2019, a construction worker in his late fifties was working on a school construction site where a retaining wall was being built. At the time, the wall was around 1.8metres high but still incomplete and without proper support in place. Despite this, a large quantity of aggregate was tipped directly against it. The wall had not been designed or reinforced to withstand such pressure at this stage of the build, and the weight of the aggregate caused it to give way. The wall collapsed suddenly, and the man, who was working nearby, was crushed beneath the falling structure and heavy material, suffering from fatal injuries.
The Investigation and Findings
The Health and Safety Executive (HSE) launched an investigation and found serious failings in how the work was managed. Key findings included:
- Lack of Planning – There was no safe plan for how the wall would be built in stages or how it would be supported until finished. The risk of collapse was not considered.
- Unsafe use of aggregate – Large loads of aggregate were placed directly against an unfinished wall. At that stage, it had no structural capacity to resist the pressure.
- No temporary work designs – A proper temporary works design was missing. Temporary works (like support, braces, or framework) are crucial to keep structures safe until they are completed.
- Failure to follow guidance- Industry guidance on temporary works was not applied. If followed, it would have flagged the need for structural checks and support before loading.
- Poor supervision and communication – Workers on site were not given clear instructions about whether it was safe to store materials near the wall. Coordination between management, supervisors and operatives broke down.
HSE concluded that the death was entirely preventable had the company followed basic safety guidance on temporary works.
Legal Outcomes
The leading building firm was pleaded guilty to breaching Section 2(1) of the Health and Safety at Work etc Act 1974. The company was fined £56,775 and ordered to pay £44,000 in costs at the Court in September 2025.
HSE Inspector said: “This was a horrific incident which had heartbreaking consequences. It happened because of a lack of planning and coordination, which is all too common in construction activity. With simple clear procedures and appropriate training this incident would not have happened.”
Lessons for the Industry
This case underlines several key lessons for employers, contractors, and site managers:
1) Plan temporary work properly – Even unfinished structures must be treated as potentially dangerous.
2) Use Safe designs – Temporary supports and retaining walls should be calculated to handle realistic loads.
3) Supervise and coordinate – Workers must be given clear instructions on when it is safe to place materials.
4) Communicate across teams – Designers, supervisors and operatives need to work together and share safety information.
5) Follow HSE guidance- Tools and resources already exist to help prevent these kinds of tragedies.
Final Word
The death of the employee death shows how quickly things can go wrong when safety is overlooked. A lack of planning cost a life and left a family grieving. For the industry, the message is clear: temporary works are not temporary risks- they must be managed with the same care as any permanent structures.
