River Frome Aqueduct Raising

As part of the Great Western Electrification Scheme, ADAS has been commissioned by BAM Nuttall to provide ecological services relating to the raising of an aqueduct carrying the River Frome over the South Wales to Bristol railway line. This project involves undertaking ecological and geomorphological surveys, provision of mitigation recommendations and design advice, applying for Flood Defence Consent and undertaking the Water Framework Directive compliance assessment.

Shoreham Viaduct

BAM Nuttall commissioned ADAS to undertake ecological surveys at Shoreham Viaduct in West Sussex, due to planned maintenance works. The viaduct crosses the Adur Estuary Site of Special Scientific Interest (SSSI), meaning several consents and licences were needed to allow the gas main removal works to go ahead: Flood Defence Consent, Marine Consent and SSSI Assent.

Flood Defence Consent

Flood Defence Consent is needed for any works undertaken within 8-10m (depending on local byelaws) of a ‘main river’ (these can include small ditches and can be checked on the Environment Agency website). ADAS staff have extensive experience of the Flood Defence Consent (FDC) process and have gained consent for a number of activities for a variety of clients. ADAS recently successfully applied for FDC for a cable trench at a solar PV site in Lancashire and for works to remove a gas main from the side of a viaduct in West Sussex.
