When planning a demolition project, competency should be a central consideration from the outset.
The HSE states that clients should obtain advice from a competent demolition engineer before awarding a demolition contract. The engineer should also review the contractor’s proposed scheme before work begins. This reflects the fact that demolition is a specialist discipline: the right contractor needs more than general construction experience to plan, manage and deliver the work safely.
However, how can a client begin to assess whether a demolition contractor and its workforce are competent for the project at hand?
Trade association membership
Trade association membership can help clients understand a contractor’s standing within the industry.
Membership of organisations such as the National Federation of Demolition Contractors (NFDC) requires contractors to meet recognised standards in areas including safety and wellbeing. Through annual site audits, members must demonstrate that the appropriate systems, people and controls are in place to keep demolition sites safe, compliant and professionally managed. These audits assess members against a defined set of requirements, providing reassurance that high standards are being maintained.
Where a contractor employs an engineer who is a member of the Institute of Demolition Engineers (IDE), this can provide further assurance of professional competence. IDE membership demonstrates that the engineer is engaged with the demolition sector and committed to maintaining and developing their technical knowledge. It also gives them access to recognised industry guidance, professional development opportunities and a network of specialist demolition expertise.
However, trade association membership should form part of a wider competency review rather than being treated as a substitute for project-specific checks. Clients should still satisfy themselves that the appointed contractor has the right resources, relevant experience, competent personnel and a suitable plan for the work.
CCDO accreditation and CPCS
Another clear indicator of competency is through the qualifications of the people who will carry out and supervise the works.
The CCDO (Certificate of Competency of Demolition Operatives) accreditation scheme is specific to demolition. It provides a structured route for operatives to demonstrate the knowledge, experience and role-specific competency required to work in the sector. It helps clients and contractors identify whether an operative is working towards competency or has achieved the appropriate level for their demolition role.
For plant operators, CPCS (Construction Plant Competence Scheme) cards can provide evidence that an individual has been assessed in operating relevant plant and machinery. Where plant is being used on a demolition site, clients should ensure that the operator holds the appropriate category of competence for the machine and work they are being asked to undertake.
Cards and qualifications alone are not the whole answer, but they are an important part of establishing that people have been trained and assessed for their roles.
Relevant experience
Demolition projects vary considerably. A contractor may have a strong record in one type of work, but clients should still establish whether it has experience relevant to their particular project.
This could include experience of:
- The proposed demolition method and sequence
- The building type, height, age and structural form
- Working near occupied buildings, public areas or live roads
- Complex site constraints, restricted access or neighbouring structures
- Hazardous materials, including asbestos
- The plant, temporary works and protection measures required
A competent contractor should be able to explain how it has approached comparable projects, the risks involved and how those risks will be managed. Experience should be relevant, evidenced and matched to the demands of the specific site – not assumed because a contractor has completed demolition work elsewhere.
The client’s role
Competency on demolition projects is not demonstrated by a single card, qualification or membership badge. It is built from the right combination of qualified people, relevant experience, appropriate plant competence, sound planning and professional oversight.
Ultimately, ensuring competency is being met is a client responsibility. By seeking advice from a competent demolition engineer early, reviewing the credentials of prospective contractors and asking the right questions about experience and workforce capability, clients can make more informed appointments and help create the conditions for safer demolition work.
