• Technical Direction: offer expert direction for complex design challenges and stakeholder engagement.
• Health & Safety: drive compliance with CDM regulations and ensure safe, compliant designs; conduct audits of mechanical safety standards (e.g., HAZOP, DSEAR) and lead improvements; apply Regulation 31 for mechanical assets in water projects.
