Bored cast-in-place concrete piles - bauerfoundations
In general bored piles offer the most economical foundation as they can be constructed in a wide choice of diam- eters, typically ranging from 300 to 1,800 mm, and to depths of up to 70 m at rakes of up to 1:4. They can thus be tailored precisely to the partic- ular requirements of the building or ex- cavation.

Method Statement for the Construction of Bored Pile
The concrete will be brought up to the working level at least 1.0m above the cut-off level to ensure good quality and contamination free concrete at pile cut-off level. The Bentonite slurry displaced by the concrete will be pumped back to the desander. The concrete above cut-off level will be chipped by the Main Contractor.
