CONTRACTS

CONTRACTS

Foundation Piling completed installation of a piled retaining wall for a luxury housing development in Cowes on the Isle of Wight at the end of June.

Bull Developments is building a four-storey apartment block on a hillside site that slopes steeply towards the sea.

Foundation Piling contracts director Stephen Edmondson said: 'The coastal road running behind the development has to be stabilised and supported to enable the contractor to excavate down 4m to build the foundations and rear wall for the scheme.'

The apartments will overlook the harbour in east Cowes, with views over the Solent.

Given the nature of the site, exceptionally deep, strong, foundations were required. The wall comprises 35, 900mm diameter bored cast insitu concrete piles installed at 1.5m centres to depths of 20m. Between each pair of piles, Foundation Piling installed 500mm diameter piles up to 9m long.

Even though the road was closed for the duration of the foundation work, space restrictions on the £130,000 contract meant using a small rig to bore the smaller piles.

When the site has been excavated to basement level Foundation Piling will return to install 40, 900mm diameter piles to various depths (dependent on building loads), with an average depth of 12m.
