Our dredging studies consider all aspects of the required works, ranging from the ground conditions and the prevailing weather and ocean conditions to selecting a suitable plant to assess the optimal approach for completing each project.

We have experience in a wide range of dredging methods, dredging related issues and complimentary services.

Our services include:

  • Reclamation advisory and design
  • Dredging options assessment
  • Dredged material characterisation
  • Sand bypassing and beach re-nourishment projects
  • Unexploded and exploded ordnance (UXO/EXO) investigations
  • Port planning to define dredging needs


  • Review and assessment of relevant site data to determine project requirements and constraints
  • Identification of likely project constraints
  • Evaluation of geotechnical/ geophysical data to assess the ability to dredge
  • Evaluation of dredged material disposal options, including offshore disposal and reclamation
  • Selection of appropriate dredging equipment
  • Assessment of site conditions and associated implications for the effectiveness of dredging equipment
  • Determination of proper project execution methodology
  • Evaluation of ‘constructability’ requirements and the optimized staging of works
  • Preparation of detailed ‘internal’ cost estimates based on in-house experience and guidelines
  • Management of contractor requests for cost estimates
  • Validation and review of dredge production rates and workability limits

Quality evidence-based solutions

Reclamation and sand bypassing.

We provide an integrated approach to managing capital and maintenance dredging, reclamation, and sand bypassing.

Our reclamation modelling accurately simulates the disposal or reclamation process associated with dredging projects to optimise basin design and construction. 

Silting assessments

Silting at terminals requires regular dredging to maintain navigation channels.
