NUS-trained PhD from Indonesia admits PIE viaduct collapse result of "design mistake"

Published

on

At the Viaduct collapse trial on yesterday (13 Sep), the court heard that soon after the collapse of a PIE viaduct in July 2017, professional engineer Dr Robert Arianto Tjandra texted a WhatsApp message to his then colleague, Liu Xiayu, that the incident had been a result of a “design mistake”.
Dr Arianto Tjandra was then working for subcontractor CPG Consultants and was the person in-charge of overseeing the design of the PIE viaduct. Liu, who joined CPG in 2010, was his subordinate at the time. Liu resigned in Feburary 2018 after the incident, which killed 1 worker and injured 10 others.
The main contractor for the project was Or Kim Peow Contractors (OKP), a public listed company run by members of a family who are grassroots leaders in People’s Association. It was Dr Arianto Tjandra who approved the design and supervised the construction works for the Changi PIE viaduct. He is currently facing five charges under the Building Control Act and the Workplace Safety and Health Act.
According to Straits Times, the court heard that about five hours after the incident, Liu messaged Dr Arianto Tjandra, saying that he felt “so sorry about the accident”. “Please let me know if I can help (with) something,” he added in the text message.
In response, Dr Arianto Tjandra asked Liu to re-check the calculations for the 2 affected vertical columns of the viaduct design. After making the calculations, Liu told Dr Arianto Tjandra that the columns had not been sufficiently designed to support the weight of the viaduct.
In response, Dr Arianto Tjandra asked Liu, “Then no deck slab can be cast?”
Liu replied, “Yes. Not allowed deck slab.” Deck slab refers to the slab of concrete that would have acted as the carriageway for vehicles on the viaduct.
“Die. My prop also failed,” Dr Arianto Tjandra continued, referring to the temporary structures to support the weight of the viaduct that was under construction.
At one point, Dr Arianto Tjandra told Liu, “Btw I am out of this job soon and my PE (professional engineer) licence will be also revoked.”
Liu then asked, “Oh no!!! How come? Any mistake they point to you?”
And Dr Arianto Tjandra replied, “This is obviously design mistake.”
Subsequent WhatsApp messages between Dr Arianto Tjandra and Liu also revealed that after the collapse, the Land Transport Authority had questioned CPG’s design. In one message, Dr Arianto Tjandra told Liu, “LTA boss already questioned our design for flyover 7 & 8. The design not consistent. Some piers heavily reinforced, some are not.”
Liu responded, “We try to explain. That’s why we use propping. Anyhow, I may not know the full story. But let me know if you need help at anytime. I am also responsible for it.”
When the lawyer representing OKP asked Liu if he had meant in the WhatsApp message that the PIE viaduct collapse was due to design inadequacies, Liu said, “Correct.”
CPG now a Chinese-run company
According to Wikipedia, CPG Corporation was the corporatised entity of the former Public Works Department (PWD) of Singapore. Under Temasek Holdings, the former government department was corporatised in 1999 and renamed as PWD Corporation, before being renamed as CPG Corporation in 2002.
In 2003, it was sold to the Australian Downer EDI Group.
In 2012, Downer Group sold CPG to China Architecture Design and Research Group (CAG), which is China’s largest diversified state-owned engineering design and services company, for A$147 million. At the time, the head of CAG told the media, “This is the first time for China’s high-tech services industry to go out and successfully complete an overseas acquisition.” Hence, since 2012, CPG Corporation has become a Chinese entity.
In any case, it has been revealed that Dr Arianto Tjandra is a talent hailed from Indonesia.

He got his first degree from Bandung Institute of Technology in Indonesia. He later went to University of Sheffield to do his MSc before landing in NUS to do his Ph.D in civil engineering.
It’s not known if Dr Arianto Tjandra himself did any of the original calculations for the viaduct design but without doubt, he was the person who approved the design with those flawed calculations.

Farewell to Dr Lee Wei Ling: Rain marks solemn tribute, echoing her father’s funeral

Dr Lee Wei Ling’s funeral was conducted on 12 October 2024, in Singapore, with family members leading the procession in the rain. In a heartfelt eulogy, her brother, Lee Hsien Yang, remembered her dedication to medicine and family. Dr Lee had requested a simple ceremony, with her ashes to be scattered at sea.

Dr Lee Wei Ling was farewelled on 12 October 2024, in a solemn funeral ceremony attended by close family members and friends.

The weather was marked by light rain, drawing comparisons to the conditions during her father, Lee Kuan Yew’s funeral in 2015.

Her nephews, Li Huanwu and Li Shaowu, led the procession, carrying Dr Lee’s portrait and walking side by side under the rain, symbolically reflecting the loss felt by her family.

In his emotional eulogy through a recorded video, her brother, Lee Hsien Yang, spoke of Dr Lee’s profound contributions to medicine and her unshakable devotion to family.

He described her as a remarkable individual whose life had left an indelible mark on those who knew her, as well as on Singapore’s medical community.

Expressing deep sorrow at her passing, Lee Hsien Yang reflected on their close bond and the immense loss he felt, having been unable to attend her final farewell.

He recalled his private goodbye to her in June 2022, a poignant moment that stayed with him during her last months.

Lee Hsien Yang also reiterated Dr Lee’s wish for a simple funeral, a reflection of her humility.

In accordance with her wishes, her body was cremated, and her ashes will be scattered at sea, symbolising her desire for a modest and unobtrusive departure from the world.

LHY acknowledged the efforts of his sons, Li Huanwu and Li Shaowu, for their role in managing their aunt’s care during his absence, thanking them for their dedication to her comfort in her final days.

During his eulogy for his sister, Lee Hsien Yang also conveyed a message from Dr Lee regarding the family’s long-standing issue surrounding their home at 38 Oxley Road.

Quoting from Dr Lee’s message, LHY said: “My father, Lee Kuan Yew, and my mother, Kwa Geok Choo’s, unwavering and deeply felt wish was for their house at 38 Oxley Road, Singapore 238629, to be demolished upon the last parent’s death.”

Dr Lee had been a vocal advocate for ensuring that this wish was honoured since Lee Kuan Yew’s death in 2015.

Dr Lee and LHY had strongly supported their father’s wishes, while their elder brother, Prime Minister Lee Hsien Loong, took a different stance. This disagreement led to a public and highly publicised rift within the family.

In her final message, Dr Lee reiterated: “Lee Kuan Yew had directed each of his three children to ensure that their parents’ wish for demolition be fulfilled. He had also appealed directly to the people of Singapore. Please honour my father by honouring his wish for his home to be demolished.”

Dr Lee had maintained a private life, focusing on her medical career as a respected neurologist. She was known for her candid views, often unflinching in her advocacy for transparency and integrity.

Her professional accomplishments, combined with her strong commitment to her parents’ legacy, made her a significant figure in both Singapore’s medical community and public discourse.

Diagnosed in 2020 with progressive supranuclear palsy (PSP), a rare neurodegenerative disorder, Dr Lee faced immense physical and emotional challenges in her final years.

The illness progressively affected her movement, speech, and ability to swallow.

Despite her health struggles, Dr Lee remained actively involved in public discussions, particularly on matters concerning her father’s legacy, until her condition worsened to the point where communication became difficult.

By March 2023, her brother LHY revealed that her condition had deteriorated significantly, and he feared he might not be able to see her again due to his own circumstances.

Even in her final months, Dr Lee maintained a close relationship with her immediate family, who cared for her during her illness.

Dr Lee’s funeral and cremation mark the end of a significant era for the Lee family and Singapore.

Her legacy as a dedicated neurologist and a firm advocate for her parents’ values will continue to resonate, even as the debates over the future of the Oxley Road property remain unresolved.

The rain that fell during her funeral, so reminiscent of her father’s final farewell, added a symbolic layer to this momentous chapter in Singapore’s history.

TJC issued 3rd POFMA order under Minister K Shanmugam for alleged falsehoods

The Transformative Justice Collective (TJC) was issued its third POFMA correction order on 5 October 2024 under the direction of Minister K Shanmugam for alleged falsehoods about death penalty processes. TJC has rejected the government’s claims, describing POFMA as a tool to suppress dissent.

The Transformative Justice Collective (TJC), an advocacy group opposed to the death penalty, was issued its third Protection from Online Falsehoods and Manipulation Act (POFMA) correction direction on 5 October 2024.

The correction was ordered by Minister for Home Affairs and Law, K Shanmugam, following TJC’s publication of what the Ministry of Home Affairs (MHA) alleges to be false information regarding Singapore’s death row procedures and the prosecution of drug trafficking cases.

These statements were made on TJC’s website and across its social media platforms, including Facebook, Instagram, TikTok, and X (formerly Twitter).

In addition to TJC, civil activist Kokila Annamalai was also issued a correction direction by the minister over posts she made on Facebook and X between 4 and 5 October 2024.

According to MHA, these posts echoed similar views on the death penalty and the legal procedures for drug-related offences, and contained statements that the ministry claims are false concerning the treatment of death row prisoners and the state’s legal responsibilities in drug trafficking cases.

MHA stated that the posts suggested the government schedules and stays executions arbitrarily, without due regard to legal processes, and that the state does not bear the burden of proving drug trafficking charges.

However, these alleged falsehoods are contested by MHA, which maintains that the government strictly follows legal procedures, scheduling executions only after all legal avenues have been exhausted, and that the state always carries the burden of proof in such cases.

In its official release, MHA emphasised, “The prosecution always bears the legal burden of proving its case beyond a reasonable doubt, and this applies to all criminal offences, including drug trafficking.”

It also pointed to an article on the government fact-checking site Factually to provide further clarification on the issues raised.

As a result of these allegations, both TJC and Annamalai are now required to post correction notices. TJC must display these corrections on its website and social media platforms, while Annamalai is required to carry similar notices on her Facebook and X posts.

TikTok has also been issued a targeted correction direction, requiring the platform to communicate the correction to all Singapore-based users who viewed the related TJC post.

In a statement following the issuance of the correction direction, TJC strongly rejected the government’s claims. The group criticised the POFMA law, calling it a “political weapon used to crush dissent,” and argued that the order was more about the exercise of state power than the pursuit of truth. “We have put up the Correction Directions not because we accept any of what the government asserts, but because of the grossly unjust terms of the POFMA law,” TJC stated.

TJC further argued that the government’s control over Singapore’s media landscape enables it to push pro-death penalty views without opposition. The group also stated that it would not engage in prolonged legal battles over the POFMA correction orders, opting to focus on its abolitionist work instead.

This marks the third time TJC has been subject to a POFMA correction direction in recent months.

The group was previously issued two orders in August 2024 for making similar statements concerning death row prisoners.

In its latest statement, MHA noted that despite being corrected previously, TJC had repeated what the ministry views as falsehoods.

MHA also criticised TJC for presenting the perspective of a convicted drug trafficker without acknowledging the harm caused to victims of drug abuse.

Annamalai, a prominent civil rights activist, is also known for her involvement in various social justice campaigns. She was charged in June 2024 for her participation in a pro-Palestinian procession near the Istana. Her posts, now subject to correction, contained information similar to those presented by TJC regarding death penalty procedures and drug-related cases.

POFMA, which was introduced in 2019, allows the government to issue correction directions when it deems falsehoods are being spread online.

Critics of the law argue that it can be used to suppress dissent, while the government asserts that it is a necessary tool for combating misinformation. The law has been frequently invoked against opposition politicians and activists.

As of October 2024, Minister K Shanmugam has issued 17 POFMA directions, more than any other minister. Shanmugam, who was instrumental in introducing POFMA, is followed by National Development Minister Desmond Lee, who has issued 10 POFMA directions.

Major media outlets, including The Straits Times, Channel News Asia, and Mothership, have covered the POFMA directions. However, as of the time of writing, none have included TJC’s response rejecting the government’s allegations.
