£53m flood prevention scheme begun in Glasgow

Work for a £53M flood prevention scheme to protect residents near the White Cart Water River in the south of Glasgow has begun.

Ground improvement specialist Pennine is stabilising the hillside at Newton Means on a £124,000 four-week contract by installing 2,500 top feed vibro stone columns (VSCs).

Main contractor Carillion constructed three staggered working platforms into the hillside prior to Pennine arriving on site. The VSCs had to penetrate the artificial platforms to reach the natural hillside below, achieving varying depths of 1.5m to 6m.

The Pennine team used two bespoke rigs, the Stratacaster Mark II and the Tardis (Telescopic All-purpose Rig for Displacement Implements). The VSCs, combined with sheet piling, strengthened the natural embankment and together with a large concrete culvert, constructed by main contractor Carillion, will form a dam in the event of excessive and prolonged rainfall.

In the event of a flood, the culvert, fitted with a hydrobreak flow control devise together with the strengthened earthwork embankment, will create an artificial flood detention basin, alleviating flooding further down the river in Glasgow and Paisley.
