Abstract

The rapid growth of infrastructure in Kota Baru Parahyangan, particularly following the operation of the Jakarta–Bandung High-Speed Rail, demands road and bridge infrastructure with high structural reliability. This study aims to analyze the integrity of the bored pile foundation at Abutment A2 of the Collector Road Row 15 Bridge project, constructed within the Rajamandala Formation, an area characterized by complex karst geological features. A descriptive quantitative approach was employed using non-destructive Pile Integrity Test (PIT) to detect potential structural defects such as necking, bulging, or concrete segregation. The test results from 12 bored piles indicated that all piles are categorized as "Undamaged" (AA) with a Boundary Transit Analysis (BTA) value of 100%. Although the concrete quality is qualitatively classified as "Fair" with wave speeds ranging from 3,200 to 3,300 m/s due to the influence of the geological environment, the realized pile depth reached 23.25 meters. This figure exceeds the 22-meter design plan, thereby providing an increased end-bearing capacity on massive rock layers. This evaluation confirms that the Abutment A2 foundation possesses excellent integrity and is reliable for supporting the bridge's upper structure.
