Construction - Case Study

Dean & Dyball Construction
1999 - Present

The Dean & Dyball group of companies has carried out construction works for the public and private sectors for more than 30 years..

Dean and Dyball are one of the largest privately owned and independent construction groups in the UK. www.deandyball.co.uk The group's activities encompass civil and marine engineering, building construction, rail engineering, and property development.

Dean and Dyball have a contract with Railtrack to Maintain the Dawlish and Teignmouth Sea walls which carry the Great Western Paddington to Penzance railway line.

Ivor Mitchell, Senior Quantity Surveyor explains:

"Part of our responsibility is to monitor the beach levels, sea and weather conditions in this area. Weather and tidal conditions in a certain combination will erode the beach sand and expose the base of the sea wall. Under these conditions the sea wall and consequently the railway line is at most risk.

WeatherNet provide us with historic weather data which is plotted against surveyed beach levels to produce graphs of sand movements compared to specific weather conditions. This allows us to predict the risk to the sea wall from forecast weather and tidal conditions, and take the earliest possible response action."
