Temporary Works Coordination: Best Practice Guidance

Temporary works failures remain a significant cause of construction incidents. Proper coordination and management are essential to ensure safety on site.

What Are Temporary Works?

Temporary works are engineering works used to support or protect an existing structure or the permanent works during construction. Common examples include:

• Scaffolding and access equipment
• Formwork and falsework
• Shoring and propping
• Excavation support
• Temporary bridges and platforms

The BS 5975 Framework

BS 5975 provides the industry standard for temporary works management. Key roles include:

Temporary Works Coordinator (TWC)

The TWC is responsible for:

• Maintaining the temporary works register
• Ensuring designs are checked and approved
• Coordinating inspections and permits
• Managing temporary works throughout the project

Designated Individual (DI)

A competent person appointed to oversee temporary works management at organisational level.

Common Failure Modes

Understanding why temporary works fail helps prevent incidents:

1. 1Inadequate design - failure to consider all loads and conditions
2. 2Poor communication - design intent not understood on site
3. 3Installation errors - works not built to design
4. 4Premature removal - striking before permanent works can take load
5. 5Lack of inspection - defects not identified and addressed

Key Principles for Success

1. Early Engagement

Identify temporary works requirements during design stage to allow adequate time for:

• Design development
• Independent checking
• Procurement of materials
• Planning of installation sequences

2. Competency

Ensure all parties involved in temporary works have appropriate competence:

• Designers must understand loading, materials, and construction sequencing
• Checkers must be independent and suitably qualified
• Supervisors must understand design intent and installation requirements

3. Clear Communication

Establish clear communication protocols between:

• Design team and site team
• TWC and contractors
• All parties during design changes

4. Robust Documentation

Maintain comprehensive records including:

• Design briefs with all relevant information
• Design calculations and drawings
• Independent check certificates
• Inspection records and photographs
• Permits to load
• Modification records
