Ensuring Safety and Compliance in Decommissioning and Demolition: The Role of Temporary Works and Regulatory Standards

In the complex sectors of power generation, offshore platforms, and petrochemical plants, decommissioning and demolition projects demand meticulous planning and execution. Central to this process are temporary works - structures or systems that provide interim support and safety measures during construction activities. At JAMES Ltd, our commitment to excellence is reinforced by our active membership in the Temporary Works Forum (TWf), enabling us to stay abreast of industry best practices, regulatory standards and the sharing for information.

Understanding Temporary Works in High-Risk Industries

Temporary works encompass a range of different items and structures, including scaffolding, propping, shoring, and pre-weaking plant and large structures, designed to ensure stability and safety during the dismantling / demolition phases. In decommissioning and demolition, especially within power stations and chemical plants, these works are vital to:

• Maintain Structural Integrity: Preventing unexpected collapses during dismantling.
• Provide Safe Access: Facilitating secure entry points for workers in hazardous environments, considering temporary states on existing/dilapidated structures.
• Manage Loads: Distributing weights appropriately to avoid overloading existing structures, considering altered load paths, increased or decreased loads during dismantling and demolition.
• Protect the Environment: Containing hazardous materials to prevent environmental contamination.

Regulatory Standards Governing Dismantling and Demolition

Adherence to established standards is crucial for the safety and success of decommissioning projects. Key British Standards include:

• BS 6187:2011 – Code of Practice for Full and Partial Demolition: This standard outlines best practices for demolition, emphasizing the importance of:
  • Comprehensive Surveys: Assessing structural integrity and potential hazards.
  • Risk Assessments: Identifying and mitigating risks associated with demolition activities.
  • Method Statements: Documenting detailed plans for safe demolition procedures, ensuring the contractor has considered the various types of temporary works including the actual structure being dismantled/demolished.
  • Waste Management: Ensuring proper handling and disposal of demolition debris.
• BS 5975:2024 – Code of Practice for Temporary Works Procedures and the Permissible Stress Design of Falsework: This standard provides guidelines on:
  • Design and Implementation: Ensuring temporary works are appropriately designed and installed.
  • Supervision: Mandating competent oversight during the works.
  • Inspection and Testing: Regular checks to confirm the integrity and safety of temporary works.
• BS 5607:1998 – Code of Practice for Safe Use of Explosives in the Construction Industry: Relevant when demolition involves explosives, this standard covers:
  • Planning and Coordination: Detailed strategies for the safe use of explosives.
  • Safety Measures: Protocols to protect workers and the public.
  • Regulatory Compliance: Adherence to legal requirements governing explosive use.

The Role of the CDM Principal Designer in Temporary Works

Under the Construction (Design and Management) Regulations 2015 (CDM 2015), the Principal Designer plays a key role in ensuring that health and safety considerations are embedded throughout the lifecycle of a project. This is particularly crucial during both the pre-demolition and demolition phases, where the risks associated with temporary works must be meticulously managed.

Pre-Demolition Phase

During the pre-demolition phase, the Principal Designer is responsible for:

• Conducting Thorough Risk Assessments: Identifying potential hazards related to the existing structure, including unstable components and hazardous materials such as asbestos.
• Developing a Temporary Works Strategy: Ensuring that a comprehensive plan for temporary works is in place before dismantling begins.
• Collaborating with Designers, Structural Engineers and Temporary Works Coordinators: Ensuring that all temporary works solutions meet engineering and safety standards.
• Ensuring Compliance with Regulations: Aligning all temporary works designs with BS 5975 and CDM 2015 requirements.

Demolition Phase

During the demolition phase, the Principal Designer continues to play a critical role by:

• Ensuring Proper Implementation of Temporary Works: Verifying that the temporary works are executed correctly and safely.
• Reviewing Changes in Structural Integrity: Assessing any evolving risks as demolition progresses and ensuring that temporary works adapt accordingly.
• Maintaining Communication Between Stakeholders: Facilitating coordination between the Principal Contractor, demolition engineers, and temporary works supervisors to mitigate risks effectively.
• Monitoring Asbestos Containment Measures: Overseeing the erection of large-scale scaffolding enclosures to ensure full compliance with health and safety regulations, including adequate air filtration and negative pressure containment.
