Impact of Military Activity on New Developments

The United Kingdom's rich military history, spanning from World War I and World War II to many military training exercises, has left a legacy of unexploded ordnance (UXO) scattered across the country.

This article explores the impact of historical military activity on modern developments within the UK, highlighting the risks posed by UXO, the necessity of risk assessments, and the crucial role of UXO mitigation companies in ensuring safe and compliant construction projects.

Historical Context of Military Activity in the UK

The UK has witnessed significant military conflicts and activities that have contributed to the presence of UXO. During World War II, the Blitz saw extensive bombing campaigns on many UK towns and cities, leading to numerous unexploded bombs. In addition, substantial areas of the country have been used for military training and live-fire exercises, resulting in buried and abandoned munitions. This has left large areas vulnerable to residual contamination from our own UXO.

Types of UXO and Their Presence

The term “UXO” encompasses a range of explosive devices, including bombs, shells, grenades, and mines. These remnants are often the result of munitions failing to detonate as intended or being deliberately buried or dumped by military forces. For example, surplus ammunition was sometimes disposed of by burying it in remote locations or dumping it in rivers and coastal waters.

Over time, these forgotten explosives pose a hidden danger to modern developments. The nature of these actions also means that contamination in some areas may not be limited to a one-off item of UXO.

Reasons for UXO Being Left Behind

There are several reasons why UXO remains in the ground:

  • Failure to detonate: Some munitions were dropped or fired but did not explode due to technical failures.
  • Buried ammunition: Surplus or defective ammunition was often buried to dispose of it safely, without anyone considering the long-term risks.
  • Dumped ordnance: Coastal and river dumping of munitions was a common practice to dispose of excess stockpiles quickly.
  • Training exercises: Live-fire training exercises left behind undetonated ordnance in designated military training areas.

Risks Posed by UXO

The presence of UXO poses significant risks to modern developments:

  • Physical dangers: UXO can explode if disturbed, causing injury or death to construction workers and the public.
  • Financial impact: The discovery of UXO can lead to costly emergency responses, project delays, and potential legal liabilities.
  • Environmental risks: Explosives can contaminate soil and water, posing long-term environmental hazards.

Impact on Project Planning and Development

The discovery of UXO can have a profound impact on project planning and development:

  • Project delays: Unexpected UXO discoveries can halt construction activities until the site is cleared.
  • Financial implications: UXO emergency responses and clearance operations can significantly increase project costs.
  • Safety concerns: Ensuring the safety of workers and the public is paramount, necessitating careful planning and execution of UXO risk management.

Importance of UXO Risk Assessments & Mitigation

To mitigate these risks, it’s crucial for developers to conduct thorough UXO risk assessments before commencing any construction project. UXO mitigation companies employ a variety of techniques to detect and identify UXO, ensuring that potential risks are identified and managed effectively.

Regulatory and Compliance Requirements

While there is no specific legislation mandating UXO risk control and mitigation, CIRIA's (C681) guidelines offer good practice and information on managing related risks. These guidelines include a process for risk assessment and the implementation of site-specific mitigation strategies.

Health and safety regulations, such as the Health & Safety at Work Act 1974 and Construction (Design and Management) Regulations 2015, address the responsibility of the construction industry to protect workers from foreseeable UXO risks.

UXO Clearance and Mitigation Strategies

Effective UXO clearance involves several steps:

  • Risk assessments: Evaluating the potential risks posed by UXO to an area.
  • Site surveys: Conducting detailed surveys to identify and map potential UXO locations.
  • Removal operations: Safely removing and disposing of UXO using specialised equipment and trained personnel.

Benefits of Proactive UXO Management

Proactive UXO management offers numerous benefits:

  • Enhanced safety: Protecting construction workers and the public from potential explosions.
  • Regulatory compliance: Ensuring adherence to legal requirements and avoiding penalties.
  • Project efficiency: Reducing unexpected delays and financial overruns.

Addressing the impact of historical military activity on modern developments is essential for ensuring safe and successful construction projects in the UK. By prioritising UXO risk assessments and mitigation, developers can protect their workers, the public, and their investments, ultimately contributing to a safer and more sustainable built environment.
