Pengujian Pile Driving Analysis (PDA) merupakan metode dinamis yang digunakan untuk mengevaluasi kapasitas daya dukung dan keutuhan tiang pondasi. Penelitian ini dilaksanakan pada Proyek Pembangunan Bunker di Rumah Sakit Umum Daerah Zainoel Abidin (RSUDZA) Banda Aceh, di mana digunakan pondasi tiang bor (bored pile) berdiameter 600 mm dengan panjang 28 meter. Pondasi tiang bor (bored pile) ini sudah dibuat pada tahun 2017 dan pada tahun 2023 dilakukan evaluasi kembali menggunakan PDA Test. Sebanyak 5 tiang diuji menggunakan alat PDA dengan metode Case Method, sesuai standar ASTM D-4945-1996/SNI 8459:2017. Instrumen seperti strain transducer dan accelerometer dipasang pada kepala tiang untuk merekam data gaya dan kecepatan akibat tumbukan palu (drop hammer) seberat 2 ton. Hasil pengujian menunjukkan bahwa semua tiang memiliki nilai BTA (Bearing Area) antara 82% hingga 90%, yang mengindikasikan kerusakan ringan. Nilai daya dukung (RMX) tertinggi mencapai 160 ton, sedangkan terendah sebesar 74 ton.

Pile Driving Analysis (PDA) is a dynamic testing method used to evaluate the load-bearing capacity and structural integrity of foundation piles. This study was conducted on the Bunker Construction Project at Zainoel Abidin General Hospital (RSUDZA) in Banda Aceh, where bored pile foundations with a diameter of 600 mm and a length of 28 meters were utilized. These bored piles were installed in 2017 and were re-evaluated in 2023 using PDA testing. A total of five piles were tested using the PDA device with the Case Method, following ASTM D-4945-1996 and SNI 8459:2017 standards. Instruments such as strain transducers and accelerometers were installed at the pile head to record force and velocity data generated by the impact of a 2-ton drop hammer. The test results indicated that all piles had a Bearing Area (BTA) value ranging from 82% to 90%, suggesting minor structural damage. The maximum recorded pile capacity (RMX) reached 160 tons, while the lowest was 74 tons.
