Navigational dredging

We provide informed and reliable advice on all aspects of your dredge campaign

Our marine consultants have over 20 years’ experience advising on dredging and disposal operations in the UK.

We have experience carrying out Water Framework Directive assessments in the Thames Estuary for maintenance and capital dredge projects using water injection dredging as well as the more traditional methods such as grab and back-hoe. We have also advised on the disposal of dredge spoil including beneficial use schemes such as those at Rainham Silt Lagoons and Cliffe Pools.

Our marine consultants can provide expert advice and high quality reports for any stage or aspect of the activity including:

  • General licensing/application advice
  • Sediment quality
  • Pre-application (Screening and Scoping)
  • Particle Size Analysis
  • Application
  • Disposal options
  • Environmental Impact Assessment
  • Beneficial use placement
  • Water Framework Directive assessment
  • Licence conditions
  • Survey design
  • Monitoring requirements

Thomson’s involvement as part of the delivery team was key to producing an end product that both looked great but that also met with the design criteria, ensuring the scheme will continue to perform into the future.

One of Redrow’s placemaking principles is the creation of new or enhancement of existing wildlife habitats. We have worked closely with Thomson Ecology on a number of initiatives to ensure that the local wildlife has a suitable environment during and post construction.

Leigh Johnson, Senior Development Manager at Redrow Homes (Eastern)

The project was managed professionally, with the required updates performed clearly, concisely and on time. The field work was delivered to a high standard, with surveyors communicating and presenting themselves professionally – important as they were also representing our organisation; the quality of the fieldwork was first-rate.

"This was ABC Electrification’s first experience of working with Thomson Ecology and I have found them extremely professional and collaborative in their support in delivering this complex and challenging programme of works.”

Jane Jukes, Environmental Manager for ABC Electrification

I was very pleased with the service that Thomson Ecology provided. The surveys and associated reports were delivered professionally and on time.
