The main challenges faced during bored pile construction are: 1. The contractor must perform a thorough investigation of the soil to study its properties. The soil type decides the drilling method to be used for the construction. 2. Sometimes, the piling contractor completely relies on the past reports, and the soil investigation reports to choose a method that causes fewer disturbances to the soil nearby. 3. When the drilled hole extends below the water table, additional support must be given using steel cages or stabilizing mud. This is the main challenge faced with cohesionless soils like sand, gravel, and silt. 4. The drilling of the hole and pile construction on a cohesionless soil is complex and causes a mess.
