• Ground characterisation, parametrisation and modelling of soil and rock.
• Numerical and FE analyses of geotechnical problems, including seismic and dynamic analysis.
• Geotechnical analysis and design of innovative and sustainable structures such as:
  Routine and complex design within soil and rock, SSI and seismic SSSI, Deep and shallow Foundations, Retaining walls, Basements and Cofferdams, Earthworks, reinforced earth and geotextiles, Ground Improvement including vibrational, mixing and grouting methodologies, Ground anchors, soil nails, rock bolts etc.
• Specification for construction purposes.
• Technical construction assurance.
• Provide guidance, support, and supervision to team members, fostering their professional growth and ensuring high‑quality deliverables.
• Bid Preparation:
  Assist in the preparation of bids, ensuring all requirements are met and proposals are compelling and competitive.
