• Ensure mechanical works are completed in line with quality standards, commissioning requirements and handover expectations.
• Support testing, commissioning, system validation, documentation and client handover.
• Maintain strong relationships with the client, delivery teams, subcontractors and internal stakeholders.
• Promote and uphold Designer Group’s health, safety, quality and environmental standards at all times.
• Ensure all work is delivered in line with site rules, airport protocols, access requirements and live environment constraints.
