Slab collapse at Indonesia Jakarta Stock Exchange:Date 15-01-2018
Indonesia Stock Exchange walkway collapse due to 'loose or corroded joints', initial report finds
Loose or corroded joints may have caused the sudden collapse of a mezzanine floor at the Indonesian Stock Exchange building this week that sent visiting students plunging to the ground, a preliminary report by the public works ministry has found.
More than 70 people were injured in Monday's incident, which was captured on dramatic CCTV footage that showed a walkway giving way under the students, some of whom were trapped beneath slabs of concrete and other debris.
The accident in Jakarta's plush financial district has shocked even a country that is used to natural and manmade disasters and where safety standards are often loosely enforced.
The ministry's report said the suspended walkway fell because several cables broke away from the ceiling due to a "concentration of weight" in one spot where nearly 100 university students visiting the exchange had gathered.
he initial conclusion was that the collapse may have been caused by "loose or corroded bolts" or "shearing joints".
The report said the walkway was part of the original structure, built in the late 1990s, and not added later.
The public works ministry said its report was based on interviews with building management, visual observations and analysis of CCTV footage on social media, but added that its team did not have direct access to the site.
"Further and closer observation is required on-site, and of construction documents," it said.
The public works ministry's press department said in a statement: "We would like to convey that this report is a preliminary report of the results of a review by ministry staff, that is unofficial."
The high-rise building is part of a two-tower complex owned and developed by PT Danayasa Arthatama Tbk, part of Artha Graha group.
It houses dozens of offices, including the World Bank's Indonesia branch.
A company spokesman had earlier declined to comment on the incident. No-one from the company could immediately be reached for comment on the findings of the preliminary report.


For some of the 92 accounting students, who had arrived hours earlier from Palembang city on the island of Sumatra to take a study tour of the stock exchange, it felt like a powerful earthquake.

One said that the students, aware of Jakarta's notorious traffic jams, arrived early and were looking for a Muslim prayer room before beginning their tour.
Many had plans to fly to the resort island of Bali for a holiday after their trip to Jakarta.
"I thought it was an earthquake and I screamed when I saw many of my friends bleeding and covered with dust," Betride Septiani said.
"We didn't feel any signs like the floor swaying or anything, it was all just so sudden."
CCTV footage that was aired on television and spread widely on social media showed a floor shearing away in a few seconds under the group.
Ms Septiani landed on her back one storey below but suffered only minor injuries. Other students fainted or suffered broken bones and concussion and are being treated in hospital.
