Huge landslide in Tg Bungah hill

GEORGE TOWN: Nobody knew a natural disaster was waiting to happen until Sungai Kelian in Tanjung Bungah turned brown and silty.

The sudden profusion of laterite mud flowing out to sea was caused by a landslide even bigger than the one that killed 11 people at a Tanjung Bungah construction site last year.

But it was so far uphill – 231m above sea level – that Penang Island City Council (MBPP) had to use a drone to find it.

As it was a natural landslide, residents are now worried about the fragility of slopes in the Tanjung Bungah hill range and want tighter scrutiny on the many development projects slated for their neighbourhood all the way to Batu Ferringhi.


MBPP issued a statement on Sunday after discovering the landslide on Bukit Batu Ferringhi, in the forest reserve about 1.5km uphill of a disused Penang Water Supply Corporation (PBAPP) intake station.

PBAPP chief executive officer Datuk Jaseni Maidinsa clarified that the station had not been in use since 1999, after the Teluk Bahang Dam was completed.

An MBPP engineer said the landslide was about 40m long and 20m wide, but geo-technical experts were unable to reach the site to determine what happened because there are no jungle trails to reach it.

A group called Nelayan Tanjung Tokong shared a video on Facebook last Thursday, showing the russet brown water flowing into the sea from Sungai Kelian and expressed concern.

Tanjung Bungah Residents Asso­ciation chairman Meenakshi Ra­­man said it was worrying because the landslide happened without any human disturbance.

“It shows the hills in the vicinity are ecologically fragile, and we don’t want any untoward incidents to happen again.

“We hope the authorities will tell us what is being done to prevent further landslides,” she said yesterday.

Former Tanjung Bungah assemblyman Teh Yee Cheu said he knew the area well and believed that the landslide took place near the source of Sungai Kelian.

“I have always stressed on how sensitive the hill slopes here are. There are many underground springs in the hills,” he said.

State Works, Utilities and Flood Mitigation Committee chairman Zairil Khir Johari said the landslide happened in the middle of a forest reserve and experts need time to study the slope to understand how it gave way.

He gave an assurance that the mud washing down the river would clear up in due course without long-term damage.

Zairil also stressed that no deve­lopment had been approved near the landslide area.

“The state government’s guidelines on hill slope development are tighter than those used by the Federal Government. We will not approve developments without pro­per compliance,” he added.

Penang Drainage and Irrigation Department director Mohd Azmin Hussin said that it would be difficult to transport machinery to the source of the landslide for mitigation works.

“There are no access roads and the team will have to hike to the site,” he said. - The Star

Penang Landslide occured days after remedial works started

Cracks at Tanjung Bungah site began in June, Commissioner of Inquiry told

GEORGE TOWN: A temporary structure supporting a worksite slope in Tanjung Bungah developed cracks in mid-June, a Commissioner of Inquiry heard.

Soil Mechanic Sdn Bhd director Cheah Wing How, who was a sub-contractor of the project where a landslide killed 11 workers, said he was informed by a clerk to carry out remedial works as the granite wall had cracked.

Cheah said his team left after completing the granite works and soil-nailing works to enhance the stability of the temporary slope.

There was, however, no mention when they completed the works.

“When we returned, we found there were pile cap excavation works carried out near the slope.

“We believe there was soil movement that resulted in the cracks on the granite wall.

“We were carrying out remedial works and 11 days into the job, the landslide happened,” said Cheah, who has 20 years’ experience in the field.

Cheah was testifying on the first day of the public hearing into the landslide tragedy by the State Commission of Inquiry (SCI) at City Hall in Esplanade yesterday.

On Oct 21, last year, a landslide hit the affordable condominium project made up of two 49-storey towers with 980 units in total within the Permai Village township near the Tunku Abdul Rahman University College.

Among the 11 killed was site supervisor Yuan Kuok Wern, 27.

During the proceeding, the Penang Island City Council (MBPP) also presented eight drone videos that showed the slope and the surrounding area after the tragic incident.

SCI chairman Datuk Yeo Yong Poh said they planned to carry out a site visit tomorrow.

He also fixed the hearing to continue until Monday, followed by Feb 8 to Feb 11, March 24 to March 28 and April 18 to 25.

Other members of the commission are geotechnical expert Datuk Dr Gue See Sew and forensic geo-technical engineer from Universiti Teknologi Malaysia Prof Ramli Nazir.

The SCI was gazetted on Dec 21 last year to investigate the landslide after Yang di-Pertua Negri Tun Rahman Abbas gave his consent on Dec 6, 2017, for the appointment of the members of the commission and its terms of reference.

Meanwhile, Penang Citizens Awareness Chant Group (Chant) adviser Yan Lee said the entrance to the Teik Granite Quarry, which is located near the site where the landslide occurred, should be fenced up.

“Anyone can just walk into the site as the safety measure is not up to mark.

“We have voiced our concern to the Penang Island City Council, the Department of Environment as well as the Land and Mines Department,” he said yesterday.

Don’t just make it about worker safety issues

GEORGE TOWN: A Penang Forum member is worried that the state’s proposed inquiry into the Tanjung Bungah landslide will only focus on worker safety issues.

Meenakshi Raman, who is also Tanjung Bungah Residents Associa­tion chairman, said the inquiry should instead look at the laws that have not been followed and whether or not the Penang Structure Plan (PSP) was neglected.

“It should also look at whether the Penang Island City Council (MBPP), which has the authority to act, failed to properly do its job.

“We hope the commission will broaden its scope of inquiry,” she told press conference at the Consu­mers Association of Penang (CAP) office yesterday.

Penang Forum is a loose coalition of several civil society groups in the state.

The coalition, which includes Sahabat Alam Malaysia, CAP, Malay­sian Nature Society, Women's Centre for Change, Penang Heritage Trust, Friends of Botanical Gardens, and 25 residents’ associations and management committees, urged the state to halt all hillslope projects immediately.

It also wants the state to amend the 2009 guidelines on “special projects” to explicitly prohibit development on hill lands except for essential public services.

Forum member Dr Lim Mah Hui said the Penang Hills Watch citizens’ initiative provided the state government with information on hill cutting it collected from the public.

“In January, this site was the first case we highlighted to the state government.

“Photos of construction and hill cutting there were presented to the state government. It responded that the ‘earthwork is being monitored’,” he said.

Dr Lim said Chief Minister Lim Guan Eng wrote in the Safety Guidelines for Hillside Development in 2012 that local governments were to strengthen their geotechnical units, which process and approve applications for hillside developments, and follow up with strict enforcement.

“It says a monitoring team will be established to ensure compliance in construction and performance (of projects).

“The question is what happened then? Did the state and local governments follow their own guidelines? Or was there gross negligence?

“Such a tragedy could have been avoided,” Dr Lim claimed.

He also said parties like the State Planning Committee, MBPP’s One-Stop-Centre Committee (which approved the project), the engineers, the developer and contractors should be investigated.

CAP vice-president Mohideen Abdul Kader said Penangites’ concerns over hill development dated back some three decades.

“Remember the proposed Penang Hill development which we managed to cancel in the end? What the state must do now is look after the natural resources and listen to the NGOs.

“Public pressure can make a difference,” he said.

Another forum member, Dr Kam Suan Pheng, said the Penang Structure Plan forbade development on hill land 76m (250ft) above sea level or with a gradient of 25° and above.

“But many developers cut hillslopes, making them steeper and less stable.

“The weather is always blamed but there was no rain for the past week. So how did the landslide happen?” she asked.

Dr Kam said the Safety Guidelines for Hillside Development clearly state that “if you have a slope ... depending on the height of the slope, you need to have a buffer zone that is greater than the height of the slope.”

“From the media reports, the height of the affected slope is 10m, so there should be a buffer zone of 10m from the foothill,” she said, adding that the inquiry should explore this aspect.

Penang Citizens Awareness Chant Group adviser Yan Lee urged the developer to conduct studies on improving on-site safety measures and engage foreign consultants to make sure the project can go on safely.

“They should also make sure the deceased workers’ families are taken care of.”
