Arup’s work on updating Ciria’s C580 embedded retaining wall guidance document is expected to get underway this week with the first project steering group meeting planned.
The meeting follows on from an industry workshop event last month that identified the key themes that must be covered in the revision which is being undertaken under contract by Arup.
Surveys carried out by Arup ahead of the workshop event showed that the standard is widely used both in the UK and internationally. Respondents called for the revision to deal with the need for collaboration between designers and contractors, in particular with regard to risk and the assumptions applied at the design stage.
There were also calls for the new report to be broadened to cover soft soils and week rocks as there is considerable variation in the way these are dealt with under the current document. Respondents also called for the new guidance to address issues associated with maintenance, monitoring and inspection.
This week’s meeting will be followed by another in late June ahead of Arup working on the first draft of the report that is expected to be presented for review in autumn this year.
Ciria has said that it expects the revised C580 report to be published in autumn 2015.
