Coordination of logistics for sample collection and delivery, ensuring compliance with health and safety requirements.

Interested subcontractors must demonstrate: Proven experience in ALC surveys and soil testing for major infrastructure projects.

Technical competence in soil classification, texture, and nutrient analysis to British and European standards.

Robust health, safety, environmental, and quality management systems.

Appropriate certifications (e.g., ISO 9001, ISO 14001, ISO 45001) and familiarity with environmental and agricultural reinstatement requirements.
