Dawson Wam

PILING & DEEP FOUNDATIONS CONTRACTS

Dawson Wam has installed 700 steel sheet piles along a section of the River Lene in Nottingham as part of the new Nottingham Express Transit Line. The Bombardier-Carillion consortium was main contractor on the £80M scheme.

The sheet piles had to be installed during a 10-day railway possession.

All the piles had to be offloaded at one end of the site and transported up to 600m along the railway track before being installed by Dawson's new ABI telescope leader rig. The rig, fitted with a 60t vibro hammer, can drive piles up to 16m long. Piles were driven to refusal into the underlying sandstone using an HPH 2400 hydraulic hammer and cut off to finished level. More than 3000m 2of piles were driven and cut off with a day to spare.
