  v Write down advantage and disadvantage of using drilled pier as a foundation   Drilled piers   Drilled piers, also known as caissons, are deep foundation systems used to support structures by transferring loads from unstable soil to stable, deeper soil layers.   Advantage   1)      High load capacity 2)      Depth flexibility 3)      Minimal vibration 4)      Adaptable to site condition 5)      Cost effective for large loads 6)      Less noise pollution   Disadvantage   1)      Slow construction 2)      Soil collapse risk 3)      Difficult quality control 4)      Weather dependency 5)      Specialized equipment required    

  Drilled Concrete Piers Drilled concrete piers are used to create deep foundations for structures like residential homes, commercial buildings, and industrial facilities. They can be used in many different types of soil conditions. Applications Deep foundations Drilled piers are used to create deep foundation systems that transfer a structure's load to bedrock or soil. Unstable soil Drilled piers can be used in unstable soil conditions by socketed into more stable strata. Challenging soil conditions Bored piles can be constructed to significant depths to provide deeper foundation support in challenging soil conditions. How they are used A drilling rig is used to create deep holes. The holes are filled with reinforced concrete. The concrete must cure before the structure can be loaded. Other names Drilled concrete piers are also known as cast-in-situ piles, cast-in-drilled-hole piles, drilled shafts, and caissons. Related methods Other methods of pili...
