SINGAPORE – A construction company has been charged in court over the Tanjong Katong Road sinkhole incident in 2025 which led to a driver suffering injuries when her car plunged into the pit.
Ohin Construction was on June 11 handed eight charges in total under the Street Works Act, Workplace Safety and Health (General Provisions) Regulations, Workplace Safety and Health Act, and Building Control Act.
The large sinkhole in Tanjong Katong Road South had appeared suddenly at about 5pm on July 26, as two lanes of the road collapsed into a large pit.
A woman was taken to hospital after the car she was driving fell into the sinkhole that formed at the junction of Tanjong Katong Road and Mountbatten Road, adjacent to a PUB worksite.
Videos posted online showed a black car falling into the sinkhole when the ground suddenly gave way under the vehicle.
The woman was rescued by construction workers who jumped into the sinkhole.
At a briefing the day after the incident, PUB, Singapore’s national water agency, said a concrete structure, known as a caisson ring, had showed signs of failure around the same time the sinkhole formed.
The structure was located at an adjacent PUB worksite, where a 16m-deep shaft was being constructed to connect three existing sewer lines.
The shaft would have allowed Ohin Construction to access the underground sewer lines.
Engineers from the Building and Construction Authority (BCA) later conducted preliminary checks on the nearby One Amber condominium and the landed houses across the road.
The assessments confirmed that the buildings were not affected by the incident.
BCA said it would carry out an independent investigation into the incident, while the Ministry of Sustainability and the Environment said it would convene an internal panel to investigate the cause of the sinkhole.
