The building was a $63 million joint venture between a major Thai construction company and a subsidiary of China Railway Engineering Corporation.
Meanwhile, the Thai government announced an investigation into the 33-storey building that collapsed during the earthquake with nine workers on March 29th. The building was a joint construction project between Thailand and China.
The building, about 800 miles from the epicenter, was the only high rise to collapse from a Thai earthquake.
At a press conference on March 29, Thai Prime Minister Paetong Tarun Sinawatra acknowledged public concerns about why the only one building had collapsed in Bangkok, while similar nearby structures remained intact. She said the government plans to investigate why the government caused the structural failure of the high-rise structure as it had a reporting deadline of one week for the Public Works Bureau and the town and country.
Sinawatra said the department is being asked to investigate the head of the building design and the head of the design, which is said to be a unique “core tube + flat slab” structure.
“I’ve seen multiple clips of a building collapse from different angles. I’ve never seen any issues like this from my experience in the construction industry,” the prime minister said. “A significant portion of the budget has been allocated and the completion deadline has been extended, so we need to do a thorough investigation.”
The building, which was scheduled for completion date of December 31, 2023, was to be used as the new office of Thai Audit General.
The buildings include Thai Construction Company Italian-Thai Development Company, PLC (ITD) and China Railway No. 10 Bureau Group Co., Ltd. was a $63 million joint venture between the two companies.
ITDs are facing a liquidity crisis, where many people face delays in war-torn Burma or serious debt obligations from problematic projects.
The structural build is said to be complete
Construction of the building in Bangkok’s Chatuchak Weekend Market commercial area began in 2020 and was put on hold during the pandemic. The completion of the building’s structural components was announced on April 3, 2024 by the China Railway Bureau 10 Group.
The toppings represent the completion of the structural stage of construction, with the highest point of the building being introduced.
Following the collapse of the building, the news was quickly removed from the group’s official website and social media channels.
According to the Taiwanese CNA, with the exception of one report by Chinese financial outlet Caixin, Chinese media reports have largely shunned mention of China Railway Bureau 10’s involvement in building the building. The Caixin report was then deleted.
Chinese media reports on the collapse mention that construction is only 30% complete.
Phoenix reported that after completion, the building will “become a business card for the development of China Railway Station 10 in Thailand.”
Thailand’s Deputy Prime Minister and Home Minister Anuchin Chanbirakul told reporters when he visited the scene in the evening of the earthquake that some of the things seen in the collapse were very unusual.
“I’m not a structural engineer, but I saw it… it shows that it didn’t collapse from above. It was tears, the tears of the pillars supporting the weight of the entire building below.
However, Charnvirakul encouraged people not to jump to conclusions to avoid panic about the cause of the collapse.
“The engineers need to set up the models,” he said. “We shouldn’t speculate about this because it’s all based on science. If they’re poorly designed, then we’d say the design is inadequate.
If they are properly designed, we will look at the new causes, “pointing out that Charnvirakul will build a standard for earthquakes that may need to be increased in the future.”

Workers are still locked up
As of March 29, nine workers were confirmed to have been killed in the collapse, but about 100 were still missing.
Foreman told the outlet that the earthquake was fortunate.
Bangkok Gov. Chadchart Sittimunt said on March 29 that city officials had received 6,000 reports of cracks in buildings in the capital. They are being investigated and appropriate safety measures have been taken, he said.
