BATTERSEA POWER station's landmark chimneys in London must be demolished because they are a safety risk, developer Parkview International said this week.
Chloride corrosion of the reinforcement in the concrete chimneys has caused chunks of concrete to fall off, posing a risk to contractors working below.
The power station in south west London is undergoing a £1bn redevelopment to create a leisure and retail complex (NCE 16 September 2004).
Trial repairs to curb the deterioration of the chimneys on the Grade II listed structure over the past two years have proved unsuccessful. As a result complete demolition and rebuild is the only option (see box).
'The steering group has concluded that the corrosion couldn't be cured and the chimneys need to be rebuilt, ' said a Parkview spokesman.
He added that the corrosion could have been caused by the use of brackish Thames water in the concrete for the chimneys.
Earlier this month, Parkview submitted planning applications to Wandsworth Council to demolish and rebuild the four chimneys, which date from 1933.
