Perhitungan daya dukung pondasi yang akurat menjadi aspek penting dalam memastikan stabilitas dan keamanan struktur bangunan secara keseluruhan. Penelitian ini bertujuan untuk membandingkan nilai daya dukung ultimit (Qu) dari pondasi bored pile dengan menggunakan empat pendekatan berbeda, yaitu perhitungan manual menggunakan metode Schmertmann & Nottingham, Mayerhoff (1976), software Allpile, serta hasil uji lapangan dengan PDA (Pile Driving Analyzer). Studi kasus dilakukan pada proyek pembangunan Gedung Fave Hotel yang terletak di Banyumanik, Semarang. Hasil analisis menunjukkan bahwa metode Schmertmann & Nottingham dengan nilai Qu tertinggi sebesar 282,25 ton. Sedangkan nilai terendah berasal dari hasil uji PDA 159,61 ton. Metode Mayerhoff (1976), memberikan nilai sebesar 170,30 ton, sementara Allpile menghasilkan nilai 160,79 ton. Selisih nilai ini disebabkan oleh perbedaan pendekatan dan asumsi yang digunakan oleh masing-masing metode. Secara umum, hasil PDA dianggap paling merepresentasikan kondisi aktual di lapangan karena merupakan hasil uji dinamis langsung pada tiang. Oleh karena itu, pendekatan manual dan software Allpile dapat dijadikan sebagai estimasi awal dalam tahap desain, namun tetap perlu divalidasi melalui pengujian lapangan untuk memperoleh hasil yang lebih realistis dan dapat diandalkan.
