Bored pile adalah salah satu metode dalam proses pembuatan fondasi dengan cara melubangi tanah, kemudian memasukan besi berbentuk silinder setelah itu menuangkan beton kedalam lubang tersebut. Perhitungan bored piledilakukan pada penambahan titik, yang sebelumnya terdapat bored pile yang mengalami kesalahan dalam proses pengeboran yang telah di cor beton. Penambahan bored pile dilakukan karena daya dukung bored pile tidak sesuai dengan rencana. Kapasitas daya dukung bored pilemenggunakan data SPT. Analisis untuk penambahan bored pilemenggunakan metode Meyerhof.Daya dukung rencana untuk tiga bored piledengan rincian diameter 80 centimeter dan kedalaman 24 meter daya dukung tiang 1753,44 ton. pelaksanaan dilapangan dimana tiga bored pileyang mengalami kesalahan pengeboran dengan rincian diameter 80 centimeter dan kedalaman 16 meter dengan daya dukung tiang 1181,29 ton. Adanya kekurangan daya dukung perlu penambahan bored piledengan rincian dua bored pile diameter 60 centimeter dan kedalaman 24 meterdengan daya dukung tiang 708,90 ton. Dalam pelaksanaan pengeboran harus dilakukan dengan teliti dan koordinasi dengan baik sehingga pekerjaan berjalan dengan lancar.

Bored pile is a one of methods in the process of making the foundation by punching holes in the ground, then the hole insertedreinforcement last the pouring of concrete into the hole. Bored pile calculation performed on the addition of a point, which previosly contained bored pile is experiencing an error in the drilling process that has been cast in concrete. The addition of bored pile because the capacity of bored pile is not in accordance with the plan. Bearing capacity of bored pile using SPT result.Analysis for the addition of bored pile using the method of Meyerhof.Carrying capacity plans for three bored pile with details of a diameter of 80 centimeters and a depth of 24 meter pile bearing capacity 1753.44 tons. the implementation of the field where three bored pile drilling experiencing errors with details of a diameter of 80 centimeters and a depth of 16 meters with pile bearing capacity 1181.29 tons. Their shortcomings need to increase the carrying capacity of bored pile with details of two bored pile diameter of 60 centimeters and a depth of 24 meters with a carrying capacity of 708.90 tons pole. In the implementation of the drilling must be done with careful and with good coordination so that the work going smoothly.
