The collapse of the Hotel New World (Chinese: 新世界酒店倒塌事件; Malay: Runtuhnya Hotel New World; Tamil: நியூ வர்ல்டு சம்பவம்) occurred on 15 March 1986, and was Singapore's deadliest civil disaster since the Spyros disaster on 12 October 1978. The six-storey building situated at the junction of Serangoon Road and Owen Road rapidly collapsed, trapping 50 people beneath the rubble. Seventeen people were rescued, whereas 33 people were killed.
Frequently referred to as Hotel New World, the building in question was actually the Lian Yak Building (Chinese: 联益大厦), which was completed in 1971 and consisted of six stories and a basement garage. The Hotel New World, previously known as the New Serangoon Hotel until 1984, was the main tenant occupying the top three floors, and a branch of the Industrial & Commercial Bank (which merged with United Overseas Bank in 1987) took up the ground level. A nightclub, Universal Neptune Nite-Club and Restaurant, was situated on the second level of the building at the time of the collapse. The building had previously experienced a poisonous gas leak (caused by carbon monoxide) in some of the hotel rooms, first hitting the headlines on 30 August 1975, the day after the poisonous gas leak was reported.
On 15 March 1986, the building rapidly disintegrated in less than a minute at about 11:25 am, leaving little time for anyone within it to make their escape. Witnesses reported hearing an explosion prior to the collapse, but the police ruled out the possibility of a bomb attack. A gas explosion was thought to be a possible cause.
Immediately after the collapse, as many as 300 were feared trapped underneath the debris. Estimates dropped to 100 trapped or missing a day later, and then to 60, including 26 hotel staff and 16 bank staff unaccounted for. The figure was finally put at 33 when the official death toll was announced on 22 March 1986 after the end of the rescue effort. Amongst those killed, 23 were Singaporeans, and the other ten foreigners.
After the collapse, many passers-by began to try pulling out survivors. They were soon joined by the Singapore Fire Service (SFS), the Police Task Force of the Singapore Police Force (SPF) and the Singapore Armed Forces (SAF). A nearby business, Eagle Piano Company, became a centre for the rescue operation.
As there were survivors buried in the rubble, the rescue was a delicate operation. Debris was carefully removed as power saws and drills cut through the rubble.
Sound detectors were used to locate survivors beneath the slabs by picking up faint moans and cries. In the first 12 hours, nine people were rescued. At one time, Lieutenant-Colonel Lim Meng Kin (SAF Chief Medical Officer), along with several other SAF medical officers and two doctors from the Health Ministry, took turns to crawl through narrow spaces inside the rubble in an effort to provide assistance to trapped survivors, giving glucose and saline drips to them.
Tunnelling experts from Britain, Ireland and Japan who were involved in nearby construction for the (Singapore) Mass Rapid Transit, including Thomas "Tommy" Gallagher, Thomas Mulleary, Norman Duke, Patrick "PJ" Gallagher, Michael Prendergast, Michael "Mickey" Scott, and Tan Jin Thong, offered to assist. They became concerned that the use of heavy machinery would collapse the rubble onto those trapped. Their voluntary efforts, digging 4 tunnels under the rubble, resulted in the rescue of another eight survivors. The tunnelling experts were later honoured by the Singapore government for their efforts. Thomas Mulleary was also nominated for an O.B.E for his rescue work but refused the prestigious honour when the rest of the rescue squad was not included.
The last survivor, 30-year-old Chua Kim Choo, was rescued on 18 March 1986, having survived after hiding beneath a table.
Following the six-day rescue operation in 21 March, 17 people were rescued, but 33 people lost their lives.
Many potential causes of the accident were investigated. Surviving sections of concrete were tested to ensure they were built to proper construction standards and it was found that they were. The construction work of the underground railway – built by tunnellers who had assisted in the rescue – was investigated, even though the excavations were more than 100 yards from the collapsed building. It was found they had no effect on the building's stability.
Also investigated were the various additions made to the building after its initial construction. Air conditioning systems had been constructed on the roof of the building, the bank had added a large safe, and ceramic tiles had been fixed to the building's exterior, all adding considerably to the building's weight. It was found that the weight of these additions was inconsequential.
However, this line of investigation into weight led to the discovery that the original structural engineer had made a serious error in calculating the building's structural load. The structural engineer had calculated the building's live load (the weight of the building's potential inhabitants, furniture, fixtures, and fittings) but the building's dead load (the weight of the building itself) was completely omitted from the calculation. This meant that the building as constructed could not support its own weight. Collapsing was only a matter of time. After three different supporting columns failed in the days before the disaster, the other columns—which took on the added weight no longer supported by the failed columns—could not support the building.
According to Channel News Asia, Lian Yak Building was designed by an unqualified draftsman instead of a professional structural engineer. An investigator found that he had over-estimated the dead weight which the columns and walls could support. The draftsman claimed that the building owner Ng Khong Lim, who eventually died in the collapse incident, had appointed him to design Lian Yak Building but Ng directed that building work. The investigator also found that Ng requested to use inferior materials to build Lian Yak Building in order to reduce the cost.
On 27 April 1986, the Government of Singapore honoured five individuals for their assistance in rescue efforts, including three from Ireland, one from Britain, and a local. A dinner was also hosted by the Singapore government on 29 April 1986 for SMRT Corporation staff involved in the rescue effort, with the then Minister of Communications and Information, Yeo Ning Hong, as the Guest-of-Honour.
Following this disaster, buildings built in the 1970s were checked for structural faults, and some of them were declared structurally unsound and had to be evacuated, including the main block of Hwa Chong Junior College and Catholic High School campus at Queen Street.  The government also introduced tighter regulations on building construction; since 1989, all structural designs are required to be counter-checked by Accredited Checkers. The Singapore Civil Defence Force (SCDF) underwent a significant upgrade, in terms of training and equipment, to improve its readiness in performing complex rescue operations.
Five years after the collapse, construction work commenced on the site for a new seven-storey hotel on 28 March 1991. The Fortuna Hotel opened with 85 rooms in 1994.
On 25 September 2003, the disaster was featured in the first episode of the second season of the television series True Courage, which was broadcast on MediaCorp TV Channel 5 (now MediaCorp Channel 5). A Chinese-language version of the series, titled True Courage (逆境勇者), was also on aired on MediaCorp TV Channel 8 (now MediaCorp Channel 8).
On 27 September 2005, Seconds From Disaster portrayed the disaster in the episode "Hotel Collapse Singapore". Instead of the actual site, the program used an image of the area around 88 Syed Alwi Road (at the corner of Kampon Kapor Road) as the basis for a computer-generated reconstruction of the building and its collapse. The episode was retelecast in Singapore on 16 September 2007 via StarHub TV.
