GEORGE TOWN: The State Commission of Inquiry (SCI) tasked with investigating the Tanjung Bungah landslide in October 2017 has found the design engineer of the slope primarily responsible for the incident that claimed 11 lives.
The SCI, in its 116-page report made public, has recommended that the engineer be investigated by the police under Section 304A of the Penal Code for gross negligence.
Besides the engineer, the commission found another design engineer responsible for being “contributorily negligent” for allowing excavation to be carried out without design, engineering calculations and supervision.
Chief Minister Chow Kon Yeow said the commission found that the slope failure was a man-made tragedy and entirely preventable if those in charge had taken necessary and proper steps to ensure the stability of the slope and the safety of the workers.
“The landslide did not develop overnight, it was a disaster waiting to happen over a period of time.
“There were ample warnings which were sadly unheeded or inadequately heeded,” Chow said of the report at a press conference at his office in Komtar here yesterday.
Chow said the report, dated July 22 this year, was a result of public hearings conducted over 26 days with testimonies from 28 witnesses.
“The commission also considered voluminous documents, reports, photographs and drawings, as well as the opinions of six expert witnesses.
“The report provides further analysis of the background facts, excerpts of testimonies recorded during the hearings and findings on liability against several parties,” he said.
The commission also found the Occupational Safety and Health Department negligent for failing to take adequate steps to ascertain the extent of the danger posed by the unsafe slope, by not promptly issuing a prohibition notice after its visit to the site on Aug 18, 2017, which was two months before the fatal incident.
Chow said copies of the report would be sent to the police, Attorney General’s Chambers, Board of Engineers Malaysia and other authorities involved.
“The report also contains nine recommendations that the commission hopes will serve as guidelines and prevent such incidents from recurring,” he added.
On Oct 21, 2017, a temporary slope in the construction site of a high-rise apartment block in Tanjung Bungah collapsed while workers were trying to stabilise it. Tonnes of earth crumbled, killing 11 workers.

Chow: Agencies have to act against negligent engineers
Penang chief minister Chow Kon Yeow
GEORGE TOWN: It is up to the relevant agencies to take action against the consultant engineers who were found negligent, resulting in the Tanjung Bungah landslide tragedy, says Chief Minister Chow Kon Yeow.
“It is up to the agencies and the police to take action as recommended by the State Commission of Inquiry (SCI).
“I have also directed the Town and Country Planning Department, Penang Island City Council, Seberang Prai Municipal Council and other related agencies to come up with recommendations to improve hill development.
“It was discussed at the State Planning Committee meeting and I have directed state housing, town and country planning and local government committee chairman Jagdeep Singh Deo to head the committee and come up with the recommendations within a month, ” said Chow at Komtar here yesterday.
It was reported that the SCI tasked with investigating the Tanjung Bungah landslide in October 2017 had found the design engineer of the slope primarily responsible for the incident that claimed 11 lives.
The SCI, in its 116-page report made public, had recommended that the engineer be investigated by the police under Section 304A of the Penal Code for gross negligence.
Besides the engineer, the commission found another design engineer responsible for being “contributorily negligent” for allowing excavation to be carried out without design, engineering calculations and supervision.
Penang Island City Council engineering director A. Rajendran, who was also present at the press conference, said the stop-work order on the project was lifted after the developer completed mitigation works.“However, different engineers have been overseeing the project since work resumed some time ago, ” said Rajendran.

Construction mishap, not landslide’
mayor Yew Tung Seang.
GEORGE TOWN: The incident that claimed four lives at a beach resort in Tanjung Bungah was a construction mishap, said Penang Island City Council (MBPP) mayor Yew Tung Seang.
He said that the slope was unstable due to digging activities as the resort’s owner was building a retaining wall without informing the authorities.
“It’s not a landslide. The incident occurred after the retaining wall collapsed within the resort’s premises.
“We need to be informed of any construction activity and make sure that it is done under the supervision of engineers.
“We are monitoring the situation closely before making a decision on whether to stop the resort’s operations,” he said at a press conference after the launching of the Karpal Singh Digital Hub at SK Sungai Gelugor yesterday.
On Tuesday, four foreign workers were buried alive in a freak accident at the construction site in Tanjung Bungah.
It is learnt that the resort owner recently contracted a Myanmar worker to build a retaining wall after finding that the hill separating the resort and Jalan Batu Ferringhi showed signs of erosion.
The contractor hired three other Myanmar nationals to assist him.
Checks found that the retaining wall, which was supposed to be about 5m wide, had yet to be built but there were other retaining walls beside it.
State local government committee chairman Jagdeep Singh Deo said mitigation works along the 50m stretch of Jalan Batu Ferringhi would be completed in three to four weeks’ time.
“Although the incident happened on private land, it has affected the federal road where many heavy vehicles pass by every day.
“It is important to stabilise the road to ensure the safety of road users,” he said.
Meanwhile, Citizens Awareness Chant Group adviser Yan Lee called on the MBPP to reveal its standard operating procedures for investigating illegal earthworks done in the state.
“I hope that the council can share with us how many officers or workers are available to check on such earthworks,” he said.
GEORGE TOWN: Soil movement due to slope instability is said to be the cause of the freak landslide that claimed four lives at a beach resort in Batu Ferringhi, says Penang Public Works Department (PWD) director Shahabuddin Mohd Muhayidin.
He said preliminary investigations showed that the slope was unstable as a result of digging by a third party.
“The digging at the slope caused soil movement with a whole lot of earth coming loose.
“Right now, we are taking the necessary steps to stop further soil erosion at the slope.
“After this, we will install sheet piles to stabilise the slope,” he told reporters at a press conference in Komtar yesterday.
Following the landslide, Chief Minister Chow Kon Yeow had ordered PWD to conduct a thorough study of Jalan Batu Ferringhi to check on conditions of the road and slopes along the 15km stretch.
“If the study finds any of the slopes or roads unsafe, repair works will be carried out following recommendations from the study.
“For now, a 50m-stretch of the road leading to Teluk Bahang has been closed for mitigation work and to ensure the safety of road users.
“The mitigation work is expected to be complete within three to four weeks, and in the meantime, a flagman will be assigned at the road stretch to direct the one-way traffic,” said Chow at the press conference.
He said the state had no information on the status of the Myanmar workers who died in the incident.
“Relevant authorities will need to investigate the landowner and project owner so that appropriate action can be taken.
Chow said they have called on the police and government agencies like the Department of Occupational Safety and Health to investigate the and take action against those responsible.
“From monitoring at the site, we believe the works to build the retaining wall were carried out without professional help.
“It was just action taken by the landowner who wanted to fix a condition on the site. And, due to the way the work was carried out, it caused soil movement and eventually the soil collapsed.”
He said PWD and the Penang Island City Council (MBPP) would continue monitoring the issue.
“In this incident, the landowner should be responsible as he or she is responsible for monitoring the land.
“Although the landowner tried to take the initiative to build the wall, professional help should have been sought to ensure safer and more secure work.”
MBPP mayor Datuk Yew Tung Seang said the council would serve notices to the landowner and other parties concerned under Section 70A of the Street, Drainage and Building Act 1974.
“MBPP is investigating, and will take appropriate action against the parties involved.
“Although we have a team monitoring illegal construction, the construction work on this particular site was not visible to public view.”
Yew advised landowners to apply for permits before embarking on any construction work in future.
GEORGE TOWN: A landslide which occurred even when there was no rain to trigger it might have been due to many reasons, including human error, says an expert.
Universiti Sains Malaysia geotechnical engineering professor Prof Dr Fauziah Ahmad said the workers may have dug at the toe of the slope while trying to build a retaining wall.
“During the digging process, pressure might have been released from the top of the wall, which could already have had cracks.
Prof Fauziah said traffic vibrations could also trigger pressure and cracks on the wall.
“Once there are cracks, water will seep through over a period of time, and when it reaches the instability between backfill and the wall, the slope will collapse,” she added.
Prof Fauziah was asked to comment on the incident on Tuesday where four foreign workers were buried alive in a landslide at a construction site in Batu Ferringhi.
Universiti Teknologi Malaysia Centre of Tropical Geoengineering director Prof Dr Edy Tonnizam Mohamad said the stability of a slope, among others, depends on its soil properties, slope geometry, volume, effect of gravity and also the pore water pressure.
“A slope could fail if one or a combination of factors passed its equilibrium and factor of safety.
“If the geometry of a slope is not properly designed according to geologic, engineering and climatic factors, a slope failure could occur.
“There have been several cases of landslides even when there was no rain,” he said.
Prof Edy added that to prevent such incidents, monitoring and inspection before and during construction is important.
“Professional supervision is also needed at the construction site.
“During construction, the standard operating procedure should be made clear.
“The construction site should be managed properly and safety procedures adhered to,” he said.
‘Owner built walls on his own’

GEORGE TOWN: The owner of a resort along Jalan Batu Ferringhi may have been building walls on his own to prevent soil erosion for some time before a landslide struck, killing four foreign workers.
Penang Works, Utilities and Flood Mitigation Committee chairman Zairil Khir Johari said there were signs of such efforts but the authorities had never been informed.
“It appears to me like he had been doing it on his own, without informing the authorities,” he said.
Attempts to contact the resort owner for comments were futile as of press time.
On Tuesday, four foreign workers were buried alive in a freak landslide at a construction site in Batu Ferringhi at 9.21pm.
George Town OCPD Asst Comm Che Zaimani Che Awang said all four bodies had been recovered.
He added that three of the victims were discovered in a standing position while holding the metal poles for the retention wall while the other was leaning over.
He said the victims did not have any identification papers.
It is learnt that the resort owner had recently contracted a Myanmar worker called Ong to build a retaining wall after finding that the hill separating the resort and Jalan Batu Ferringhi showed signs of erosion.Ong then hired three other Myanmar nationals, to assist him.Checks found that the retaining wall, which was to be about five metres wide, had yet to be built but there were other retaining walls beside it.
The exposed slope has been covered with tarpaulin sheets to prevent further erosion.
Deputy Chief Minister I Datuk Ahmad Zakiyuddin Abdul Rahman, who is the
committee chairman, said the MBPP as the owner of the project had failed
in its overall responsibility to supervise the project despite having

MBPP among four named as responsible in fatal Penang landslide
GEORGE TOWN: Four parties have been identified as being responsible for the fatal landslide at the construction site of the paired road at Jalan Bukit Kukus last October incident, including the Penang Island City Council (MBPP).
A special investigation committee set up by the Penang government following the fatal landslide at the construction site also named the other three parties, namely the contractor Yuta Maju Sdn Bhd, the consultant, Jurutera Perunding GEA (M) Sdn Bhd and the independent checking engineer G&P Professional Sdn Bhd.
Deputy Chief Minister I Datuk Ahmad Zakiyuddin Abdul Rahman, who is the committee chairman, said the MBPP as the owner of the project had failed in its overall responsibility to supervise the project despite having appointed Jurutera Perunding GEA as representative of the superintendent officer.
“By appointing Jurutera Perunding GEA, it does not mean that the council is free from responsibilities to ensure the success of the project from all aspects.
"As such, any actions to be taken against the council will depend on the outcome of investigations by the police, the Department of Occupational Safety and Heath (DOSH) and the Construction Industry Development Board (CIDB) into the incident," he said when making public findings of the investigation committee.
Ahmad Zakiyuddin said as for Yuta Maju, it had failed to ensure satisfactory mitigation works at the project site, and that the temporary slope constructed at the project site was not endorsed or designed by accredited consultants, which was a violation of the Board of Engineers Malaysia (BEM) guidelines.
“It also failed to ensure site safety by removing the empty containers at the project site, where nine bodies were recovered," he added.
As for Jurutera Perunding GEA, Ahmad Zakiyuddin said the party had failed to ensure that the contractor abide by the guidelines set out by the BEM, while G&P Professional had failed to abide by the job scope given by the council.
“Following our findings, we have recommended that the contractor, consultant and independent checking engineer be blacklisted from any tender consideration for projects in the future.
“That said, they will still have to continue their works for the paired road project, until the project completion, slated for May next year,” he added.
The landslide at the Bukit Kukus paired roads project site on Oct 19 last year killed nine site workers and left four others injured.
The search and rescue (SAR) operation was called off after five days. The project's stop-work orders, separately issued by DOSH, CIDB and the council, were lifted up recently.
Ahmad Zakiyuddin said the special investigation committee also identified 10 main factors which had contributed the to fatal landslide, particularly not fully adopting best practices in construction work.
Other factors included:
* heavy rain on the morning of the incident at 55mm
* the contractor was unable to enter the project site to carry out mitigation works as stop-work order was issued by DOSH two days prior to the incident following a worksite accident
* unsafe construction processes
* failure to recognise the significance of an earlier incident (falling beams at another part of the project site two days prior to the landslide);
* lack of supervision
* failure to identify risk due to the change of process
* lack of comprehensive inspection and testing
* failure in risk communication
* poor management of sub-contractors.
Asked on why the services of the contractor, consultant and independent checking engineer were not immediately terminated following the incident, Ahmad Zakiyuddin said from what he understood, the stop-work orders issued on the three were only for one part of the project and not the entire project.
"Also, there was no record of safety issues prior to the landslide," he said.
He called on efforts to protect the remaining part of the project as a resu
lt of a negative perception.
"Any delay will put the project at greater risks."
To another question if the special investigation committee's findings would be made public, he there had been no plans to do so as the report served as a guideline for the state. - By Audrey Dermawan, NST >
‘MBPP hired resident engineer for Bukit Kukus project’
GEORGE TOWN: The Penang Island City Council (MBPP) appointed a resident engineer and an independent checking engineer even before the start of the Bukit Kukus paired road project, says Chief Minister Chow Kon Yeow.
“If you see the action taken by MBPP, they understand their technical insufficiency in terms of a geotechnical engineer. That’s why in the contract, they required the main contractor to appoint a resident engineer, who was paid by MBPP to monitor the project on MBPP’s behalf.
“The independent checking engineers were also paid by MBPP. So, it was a measure taken by MBPP even before the start of the project, knowing that this is a big project.
“They did not have the capacity to monitor the project as they have only two or three engineers who have to be looking at other matters besides this project.
“So, they took action to appoint a resident engineer as well as independent checking enginners to act on behalf of MBPP,” he told reporters at the Penang Development Corporation Chinese New Year celebration at the PDC office in Bayan Lepas yesterday.
Chow also said the state would wait for the Department of Occupational Safety and Health (DOSH) report first.
“We will leave it to DOSH’s findings. Let DOSH come out with the report and we will take the necessary action after that,” he said.
Asked if MBPP had to bear necessary compensation for families of the victims of the landslide last October, Chow said MBPP had not received any claim so far.
Chow was asked to respond to the Consumers Association of Penang’s (CAP) call for stern action to be taken against the wrongdoers responsible for the tragedy.
CAP president S.M. Mohamed Idris in a statement yesterday said: “While we welcome the investigation committee’s findings as to who is responsible for the tragedy, we are concerned that apart from recommending the blacklisting of the contractor, consultant and independent checking engineer from any tender consideration for future projects, it appears that no further stern action has been recommended.
“In particular, we want to know what action will be taken against MBPP,” he said.
Deputy Chief Minister I Datuk Ahmad Zakiyuddin Abdul Rahman, who headed the investigation panel, was reported yesterday as saying that MBPP and other parties involved in the construction of the Jalan Bukit Kukus paired road project had not adhered to construction and engineering best practices.
Meanwhile, MBPP acknowledged responsibility for the Bukit Kukus landslide tragedy as it is the council’s project.
MBPP mayor Datuk Yew Tung Seang said the council was not pushing away any responsibility or negative comments on the council and project, and that it would be taken seriously. - By Cavina Lim and Intan Amalina Mohd Ali, The Star
Penang landslide report blames contractor, MBPP and DOSH
The special investigative panel report on the Bukit Kukus landslide had not been made public, but excerpts of the findings were made available by the state.
However, it has raised more questions than answers as the state blamed the contractor, Penang Island City Council (MBPP) and the Department of Occupational Safety and Health (DOSH).
In an immediate response, DOSH Penang director Jaafar Leman denied the department was to be blamed for the landslide.
“We were not even invited to be part of the investigative panel to give our views. How could we be blamed?” he asked.
According to the statement by Deputy Chief Minister 1 Datuk Ahmad Zakiyuddin Abdul Rahman who headed the investigative panel, the stop-work order on Oct 17 prevented contractors from entering the site to do maintenance works.
As a result, the temporary toe drain overflowed and water was retained on the reclaimed land contributing to the collapse of the slopes.
“How could a stop order which was issued on Oct 17 contribute to the landslide which occurred on Oct 19?” asked Jaafar.
He said the slopes would have been risky from the beginning as the contractor did not do any mitigation works to strengthen them and it does not make sense to blame DOSH.
The stop-work order was issued on Oct 17 after 14 beams fell in a ravine.
Earlier, during a press conference, Ahmad Zakiyuddin said MBPP and other parties involved in the construction of the Jalan Bukit Kukus paired roads project, had not adhered to construction and engineering best practices.
“The landslide was caused by many factors, which included a temporary construction of a platform to place machinery which was not constructed properly. The temporary platform was created to allow heavy vehicles lift beams for the paired road project.
“MBPP, as owners of the project, had failed to ensure all the hired parties carried out their job.
“MBPP had failed to hire a professional engineer for temporary works to design and supervise the site,” he said yesterday.
Ahmad Zakiyuddin said another factor was the downpour in the morning of the day of the landslide.- The Star
Kudos to Deputy Chief Minister I Datuk Ahmad Zakiyuddin for holding the four parties accountable for the Bukit Kukus landslide
tragedy. The inquiry still begs a lot of questions, e.g. why was the
contract given to Yuta Maju from Terengganu? Could the accident have
been prevented if a proper EIA was done? It is not just a "bureaucratic
hurdle" but supposed to identify risks and advise mitigation. If the
authorities wish to go on with the project, it is not too late to
commissi... See more
“This
is no simple incident as nine deaths resulted from it. Very stern
action must be taken against the MBPP, and that includes strong
disciplinary action against the mayor and officers responsible.
“Otherwise, it will be business-as-usual in the MBPP as the officers will be allowed to go scot-free with impunity.

Malaysia among countries especially prone to landslides
Malaysia sits among the top 10 countries that had a high number of landslides over the past decade.
According to data from the US National Aeronautics Space Administration (Nasa), Malaysia had 171 landslides between 2007 and March 2016, making the country ranked the 10th highest in frequency of landslides.
Ranked first is the United States (2,992), followed by India (1,265) and China (426).
Titled the Global Landslide Catalog (GLC), the one-of-its-kind dataset was compiled based on online and media reports, and scientific journals since 2007.
The Star analysed the dataset and found that the number of landslides have been increasing in Malaysia, almost with each year, reaching a peak of 33 occurrences in 2014.
On average, in the past 10 years, Malaysia experienced 18.5 landslides annually.
The high number of landslides means that Malaysia ranked 5th for landslides per square kilometre among countries that have a land area greater than 100,000sq km.
Nepal is the country with the highest number of landslides per square kilometre, followed by the Philippines, Britain and Guatemala.
Most of Malaysia’s landslides occur between October and January, which coincides with the months with the highest rainfall. This is according to data on average monthly rainfall between 1991 and 2015 from the World Bank.
Sabah leads with the most number of landslides (42), followed by Kuala Lumpur (26), Sarawak (25), Selangor (22) and Penang (14).
Latitude and longitude data point towards certain areas that landslides commonly occur. These include Ranau in Sabah, Ringlet in Cameron Highlands, Bukit Antarabangsa in Selangor and Tanjung Bungah in Penang.
Nasa’s satellite view showed that most landslide occurrences in Malaysia are packed around the peninsula’s west coast, and Sabah and Sarawak.
Hardly any red dots could be seen in the Kalimantan region, south of Sabah and Sarawak, which could indicate that the landslides are caused by over-development.
Based on Nasa’s GLC website, since 2007, it has recorded some 10,000 landslides around the world, leading to more than 20,000 deaths, mostly in South-East Asia.
Data on Malaysia showed that most landslide fatalities are in Kuala Lumpur (18), followed by Pahang (17) and Selangor (eight).
The GLC project, first published in 2010, was to provide scientists with a dataset to analyse how, why and where landslides are likely to occur.
It remains the largest publicly available repository of global landslides.
According to the Meteorological Department, the country will be experiencing the northeast monsoon until the end of March, with heavy rains forecast along the east coast of Peninsular Malaysia, eastern Johor and Pahang.
A higher than average rainfall level of between 250mm and 350mm is also forecast for certain places in Sabah such as Kudat and Sandakan. In Sarawak, Kuching, Samarahan, Bintulu and Kapit are forecast to receive an average rainfall level that exceeds 500mm.
'Main cause is man-made'
Malaysia’s rugged topography and high rainfall coupled with human activities are behind the country being among the top 10 countries with the most number of landslides.
Institute of Geology spokesman Ng Chak Soon said Nasa’s data was correct.
“This is due to a combination of natural factors and human activities. Natural factors comprise periods of high rainfall and rugged topography while human activities relate to the cutting of slopes,” he said in an interview.
Asked if the high frequency could also be due to the type of soil in Malaysia, Ng said this was true only for Sabah such as in Ranau.
“Sabahan soil seems to have a high percentage of expandable clay which absorbs more water and expands more when wet. It shrinks when dry,” he said, adding that earthquakes were also a new factor in the state.
Not a country with typhoon or volcanic eruptions, Ng said the country’s only threat came from landslides.
“And, this is mostly man-made.
“Practically every major landslide in this country is linked to engineering works where slopes have been cut or built or filled with material,” he said.
To a question whether Malaysia had to change its type of development work such as slope cutting to reduce landslides, Ng said: “Apart from the coastal plains, most of our country is hilly.
“That means slope cutting is inevitable.”
He said there was a lack of in-depth understanding of the underlying factors behind landslides among “experts” in the country.
Whenever a slope failed as part of engineering works, he said it was engineers who looked into the causes of failures or what could have been overlooked, overestimated or underestimated in their calculations.
“It is unfortunate that most of these reports (into landslides) are not freely available for public scrutiny,” said Ng, adding that this made it difficult to identify the causes and to prevent similar mistakes from recurring.
He also claimed there was a lack of appropriate geological input in the study into the causes of landslides.
In many countries landslides come under the ambit of their geological survey departments.
“Malaysia is the exception where the Geoscience and Minerals Department is not playing this key role and there is a very good reason for this,” said Ng.
“Landslide as a geological phenomenon is a topic under engineering geology which is itself a branch of geology.
“Landslides began to be considered a problem only after the collapse of the Highland Towers in 1993.
“So, it is relatively new in Malaysia.
“To really have a better understanding of why slopes fail, we have to get the geologists involved,” he said.
Penang Apartment dwellers live in fear
Cause for concern: A view of the construction site where the paired road project is being built in Paya Terubong.
GEORGE TOWN: For the first time in the 10 years that he has stayed in his apartment near the Bukit Kukus paired road project, 62-year-old S. Santhara is worried.
That was where nine people died due to a landslide last month.
The retired fireman never had to worry about landslides because the hills behind his apartment in Paya Terubong were covered with trees.
“We knew the hills facing our block would not crumble as the trees held down the soil,” he said.
That was before the hills were cleared for the construction of the paired road project.
“As they started to clear the hills near my home last year, I worried about the stability of the slopes and whether there would be a landslide.
“Then, the Tanjung Bungah landslide occurred in October 2017 and I fear this place could be next,” he said.
On Oct 19, the landslide at the construction site for the paired road hit 12 containers that housed construction workers.
Besides the foreign workers who were killed after being buried alive, four others were injured.
The Tanjung Bungah landslide that struck the site of an affordable housing project in Lengkok Lembah Permai killed 11 workers, including a Malaysian.
A special committee, set up by the Penang state government, will begin investigations into the cause of the Nov 8 landslide at the Bukit Kukus project site in Paya Terubong.
Inquiry into the Tanjung Bungah landslide has yet to be completed.
The Bukit Kukus landslide, said Santhara, had taken place right behind the hill facing his apartment block.
Now, he said it was worrying whenever it rained.
“Anything can happen at any time. If I have the opportunity, I will move out,” he said at his home.
Already, he said, there was landslip on parts of the hill after the trees were cleared.
“There was erosion. It (the hill) has now been covered with sheets but we still worry when it rains.
“During rainfall, a lot of mud water wash down and drains overflow, spilling onto the road,” he said.
On the day of the landslide, K. Kalaiselvan, 43, who lives on the 18th floor of an apartment in the vicinity, heard a loud crash.
“It sounded like rocks and sand falling. Later, I realised it was a landslide.
“I am worried we could be next,” he said, adding that the slopes were bare and threatening.
“I run a coffee shop and have lived here for the past 15 years. This is my home.
“As I live on a really high floor, it is worrying whenever it rains,” he said.
Engineers: Put plan for a centralised agency into motion
PETALING JAYA: Set up a centralised national agency to really control slope safety, suggests the Institution of Engineers.
Its president David Lai (pic) said IEM had proposed the setting up of such a body years earlier and hoped that the government would look into this urgently.
“We had actually put in a position paper in 2002 on the classification of slopes into four categories according to the height and angle of the slope.
“We also had an update on the policy in 2009,” he said in an interview, adding that the two papers were conveyed to the Housing and Local Government Ministry that looked into building by-laws.
“We are still actively pursuing this matter,” said Lai.
He said there should also be a slope information management system put in place to identify risky zones.
“The government must take the lead in coming up with such a system. We can give recommendations but the government is the statutory body,” said Lai.
He was responding to Nasa data that put Malaysia among the top 10 countries with the most frequent landslides in the world between 2007 and 2016.
Lai said Malaysia should learn from Hong Kong which had to deal with several landslides in the 1980s until it set up a geo office.
“From then, they started to repair the old slopes and impose new guidelines. Now, they have managed to control slope failure,” he said.
He said IEM, which had some 48,000 members, had put in a recommendation that for development on critical slopes between 25° and more than 35° angle, there should not only be a submissions engineer but also a geo-technical specialist to check on the design.
Asked if there was a need for engineers to change their designs such as cutting or fortifying the slopes, Lai said: “We actually don’t need to change.
“We just need to make sure to put in place the required safety procedures.
“We just need to get the correct people and whether all these procedures have been implemented.”
He added that enforcement was a necessity.
He said with more hillside development, there was a need now for specialised geo-technical engineers, who knew soil conditions and behaviour, and incorporate this into slope design.
PWD working to keep landslides down
The Public Works Department (PWD) has been carrying out landslide prevention works on slopes along federal and state roads beginning this year.
The works, undertaken by its Slope Engineering Branch, will go on until 2020.
Among the measures being undertaken include evaluation, danger and risk mappings, and setting up of an early warning, real-time system for landslides.
Its director Zulkifly A. Ghani said the prevention works also included fortifying high-risk slopes along federal roads.
“For slopes along federal reserve and state roads, monitoring is being carried out by the district PWD via the visual method, such as site visits and inspections,” he said in an interview.
Zulkifly was responding to a question on the action taken by the department to monitor the slopes, particularly during the rainy season.
Last year, former works minister Datuk Seri Fadillah Yusof said 946 of the 16,454 slopes along federal roads in Peninsular Malaysia were classified as “very high hazard” while 1,551 others were “high hazard”.
Zulkifly concluded this with the latest technology of Light Detection and Ranging and drones.
“The Early Warning System is being developed,” he said.
Zulkifly said the EWS was being developed using monitoring techniques such as rain gauge, robotic total stations as well as the Global Navigation Satellite System.
“The equipment will continuously monitor any slope movement and the data transmitted to a server for analysis and displayed on a special website.
“Should the movement reach the danger limit, it will send a message to the officer via SMS. The officer will then decide what to do,” he said.
Forty-eight rain gauges had been installed at risky slopes.
“The real time warning limit is displayed on a special early warning website for landslides, which however is still being developed and improved on by the branch,” he said.
