• Ensure compliance with CDM regulations, HSWA, LOLER, PUWER and the Balfour Beatty Temporary Works Management Procedure.
• Ensure internal and subcontractor designs meet the temporary works design brief, required timescales and technical approval requirements, including Approval in Principle submissions for clients and external stakeholders.
• Identify, assess and communicate design and residual risks, maintaining a strong focus on Zero Harm and applying the principles of prevention through design and engineering.
• Mentor junior engineers, support continuous improvement of design processes and tools, and report on temporary works design resolution and interfaces with permanent works and subcontractor designs.
• Support development and implementation of digital processes/culture/technology to support project delivery during the Design, Construction and Handover phases.
