Geotechnical Consultancy

Ice House, Hastings, East Sussex

We were asked to assist in the design of stabilisation works to an existing retaining wall that was supported by a substantial structure (Ice House) that was to be demolished. The retaining structure was to be retained and integrated into a new residential / commercial development. An investigation was designed to provide information for the modelling of the soil and bedrock profile to enable stability analysis of the wall and design of an alternative support system for the wall. A detailed specification for anchoring of the wall was developed by us, enabling the safe demolition of the Ice House Structure and replacement with the new development. 
 

Staplecross, East Sussex 

The Site at Staplecross comprised an unregulated landfill within an Area of Outstanding Natural Beauty. Following a number of appeals, an application for retrospective planning permission was ultimately successful, but subject to rigorous planning conditions requiring a stable and suitable landform to be designed and implemented. We were requested to investigate the Site and develop a stable landform in conjunction with landscape architects, arboriculture specialists and planning consultants. In addition our attendance at planning appeal hearings in the capacity of expert witness was also required. Following completion of site investigation works and detailed design of a slope stabilisation the scheme design was submitted to the local authority. Subsequent to a comprehensive review by the local authority and their geotechnical advisors the scheme was accepted enabling discharge of key planning conditions.

St Leonards-on-Sea, East Sussex

We were requested by structural engineers to assist in the design of a residential development in an area of former landslip.

A comprehensive ground investigation was designed to enable the cause of the slip and the stability of the properties to be assessed. The investigation included the organisation of a topographical survey, the excavation of exploratory holes and the installation of instrumentation for long term monitoring. The report on the investigation included a range of remediation options. We were actively involved in the subsequent option appraisal process. The favoured option comprised extensive ground drainage in combination with shallow retaining structures and piled foundations. We developed a geotechnical design statement to support the planning application.
