Industrial facilities constructed on peat may exhibit different damage patterns even within the same site because their support systems translate ground movement into different structural responses. This study investigates foundation-dependent damage signatures at a crude palm oil bulking station in Kota Bangun, East Kalimantan. Evidence from 41 visual observation points, topographic measurements, two CPTu soundings, two boreholes with SPT, and non-destructive concrete and steel tests was integrated using a diagnostic comparative case-study approach. The site is underlain by fill over very soft and peaty layers, with an observed elevation loss of approximately 50–80 cm. Four damage signatures were identified: ground-supported elements followed soil settlement; shallow foundations developed settlement and angular distortion; limited or nonuniform pile support tended to rotate and distress connecting elements; and denser pile groups maintained better global geometry while concentrating damage at interfaces with ground-supported surroundings. Variations in concrete quality and steel deterioration were interpreted as local vulnerability factors rather than the sole cause of the site-wide damage pattern. The results demonstrate that foundation type controls how peat settlement is manifested as structural damage and should therefore guide monitoring, repair, strengthening, or reconstruction decisions.
