Construction Site Safety: Common Issues Found During CDM Audits

Construction site safety is a legal requirement under the Construction (Design and Management) Regulations 2015 (CDM 2015), but it is also essential for protecting workers, reducing incidents, and keeping projects on track. One of the most effective ways to ensure compliance is through regular CDM audits.

However, CDM audits frequently uncover the same recurring safety issues across construction sites. Understanding these common findings can help duty holders take proactive steps to improve safety performance and avoid enforcement action.

1. Inadequate Construction Phase Plans

A poorly developed or generic Construction Phase Plan (CPP) is one of the most common non-conformances found during CDM audits. Typical issues include:

• Plans not tailored to the specific project

• Missing site-specific risks and control measures

• Failure to update the plan as work progresses

Under CDM 2015, the Construction Phase Plan must clearly demonstrate how health and safety will be managed throughout the construction phase. A well-prepared plan is a key indicator of effective site management.

2. Poor Quality Risk Assessments and Method Statements (RAMS)

CDM audits frequently identify weaknesses in risk assessments and method statements, including:

• Generic or copied RAMS

• Hazards not fully identified

• Control measures that are impractical or not followed on site

RAMS should accurately reflect how work is carried out and be clearly communicated to the workforce. Auditors will often speak directly to operatives to confirm whether safety procedures are understood and implemented.

3. Lack of Competence Evidence

Demonstrating competence is a fundamental requirement under CDM 2015, yet audits often reveal insufficient evidence for:

• Subcontractor competence checks

• Training records and certifications

• Adequate supervision arrangements

Failing to verify competence increases the risk of accidents and exposes duty holders to enforcement action. Maintaining clear records and ongoing competence reviews is essential for CDM compliance.

4. Inadequate Welfare Facilities

Welfare provision is a legal requirement and a frequent focus during CDM audits. Common issues include:

• Insufficient toilets or washing facilities

• Poor cleanliness or maintenance

• Lack of drinking water or suitable rest areas

Auditors often view welfare standards as a direct reflection of a company’s overall commitment to construction site safety and worker wellbeing.

5. Poor Communication and Safety Engagement

Even when safety systems are in place, CDM audits often highlight failures in communication, such as:

• Workers unaware of site-specific hazards

• Limited or ineffective toolbox talks

• No clear process for reporting near misses

Strong safety communication ensures that procedures are understood, followed, and reinforced across the site.

6. Failure to Review and Update Safety Arrangements

Construction projects are constantly changing, but safety documentation is often not updated accordingly. CDM audits regularly identify:

• Outdated Construction Phase Plans

• RAMS not reviewed following changes or incidents

• Lack of formal safety reviews

Regular reviews are essential to ensure that safety arrangements remain suitable and effective as site conditions evolve.

Strengthening CDM Compliance Through Proactive Safety Management

Many of the issues identified during CDM audits arise from gaps in planning, communication, and ongoing review rather than a lack of intent. By strengthening construction site safety processes, maintaining up-to-date documentation, and ensuring competence across all roles, duty holders can significantly improve compliance with CDM 2015.

A proactive approach to health and safety not only supports better audit outcomes but also helps create safer, more efficient construction sites. Regular reviews, meaningful worker engagement, and professional safety support ensure risks are controlled as projects progress.
