The scheme was to install 48No, 350mm diameter CFA Bored piles to an average depth of 23m.

Installing piles next to an English heritage site meant there were a few issues that had to be overcome first before work could commence.

• Working very close to the over hanging mast of the SS Great Britain, one of the most iconic ships of the 19th Century.
• Narrow access to site through listed gates
• The need to minimise piling platform track pressures whilst working on the site sandwiched between two delicate 18th century dock walls
• Very poor alluvial soils extending up to 20m, required the use of the latest computer aided monitoring to ensure integrity within thes soft soils whilst the pile penetrated approx 3m into the competent Redcliffe Sandstone at depth
• The confined site required piling across its whole footprint, so our latest innovation a tracked combined agitator and pump, allowed quick movement of the agitator, reducing the size of attendant the excavator provided by the main contractor Beard Construction.
• Low vibration and noise whilst working adjacent to this popular visitor attraction run by the SS Great Britain charitable trust
