Ohin Construction Charged Over Sinkhole

A construction company, Ohin Construction>>>, and six individuals linked to its project, including managing director Ivan Ong Khiaw Yang>>>, project director Raajkumar Nadarajan>>>, project manager Sellappan Saravanakumar>>>, 'qualified persons' Kee Chun Siang>>> and Yau Tze Yin>>>, and resident engineer Senthilnathan Mathyalakan>>>, have been charged in a Singaporean court. The charges, primarily under the Workplace Safety and Health Act and Building Control Act, stem from alleged construction lapses that led to a sinkhole on Tanjong Katong Road South in July 2025. The sinkhole caused a car to plunge into the pit, injuring the driver. Allegations against Ohin Construction>>> include constructing jet grout piles with smaller diameters than approved, failing to conduct required tests, creating unapproved openings in caisson rings, and casting a non-circular caisson ring. The company also allegedly failed to notify authorities of a road depression before the sinkhole formed. Ohin Construction>>> has since been provisionally liquidated. Separately, Pub, Singapore's national water agency, and Surbana Jurong>>> Consultants received conditional warnings under the Building Control Act following investigations by the Singapore — Ministry of Manpower>>>, United Arab Emirates — Roads and Transport Authority>>>, and Singapore — Building and Construction Authority>>>. Works for the project remain halted, pending new structural plans and safety assessments.
