Engineering Consultant gets show-cause letter for ‘overlooking hilltop stream", the main cause for landslide



Consultant gets show-cause letter for ‘overlooking hilltop stream’


GEORGE TOWN: The consultant of the Bukit Kukus Paired Road project has been slapped with a show-cause letter for allegedly overlooking a stream on top of the hill before commencing work.

Penang Island City Council (MBPP) mayor Datuk Yew Tung Seang said the stream had been blocked, and this could be the main cause for the landslide on Friday.

“We found the stream on top of the hill on Saturday morning.

“You don’t need an expert to tell you that a diversion was needed in this situation before starting work on the hill.

"For me, this (the blocked stream) could be the main cause for the landslide,” he said at the site in Paya Terubong yesterday

The contractor has since diverted the flow of water

Yew also said stern action would be taken if professional negligence was found to be the cause once the investigation was completed

“This is a straightforward engineering project that needs to comply with standard operating procedure.

“We want to know why the need to divert the water was overlooked. I believe the tragedy could have been prevented,” he added.

Asked about the project, Yew said it would go on.

“I hope the project will be completed on time and in proper order by 2020.”

The RM530mil alternative road linking Lebuhraya Thean Teik in Bandar Baru Air Itam to Lebuh Bukit Jambul began in January 2016.

So far, nine bodies have been recovered from the scene. They included Indonesian worker Subaeri, 34, found at about 12.45pm yesterday and Bangladeshi Muhammad Uzzal, 33, at 5pm.

Muhammad Uzzal is said to be without a valid working permit.

Firemen found his body pinned under a container and took about 40 minutes to extract it before sending it to the Penang General Hospital for a post-mortem. The bodies of Bangladeshi workers Mithu Hossain, 30, Mustak Hossain, 25, and Md Jalil, 34, were pulled out of the rubble on Sunday.

Hill stream overflowed - Heavy rain, water on slope cause of Bukit Kukus landslide

Rescue operations at Jalan Bukit Kukus Paya Terubong

GEORGE TOWN: Water flow from a stream on the hilly area at Jalan Bukit Kukus, Paya Terubong has been identified as among the causes of the landslide there last Friday, according to the Mineral and Geoscience Department.

The department’s director for Perlis, Kedah and Penang, Azhari Ahmad, said the finding was made based on its inspection and monitoring since yesterday.

“Our team, which arrived at the location yesterday morning, conducted an observation and identified several factors that caused the landslide, resulting in all containers on the hill slope to slide down with the earth.

“The main factor that caused the land slide is the water flow from a stream near the slope, and heavy rain since Friday morning caused the water to overflow,” he said.

The department had taken immediate measure by diverting the flow of water from the stream elsewhere to avoid worsening the situation, especially during the search and rescue (SAR) operation, he said.

Azhari said further inspection conducted at 7.30am yesterday found the water flow on the slope was less, but the department will continue to monitor the situation with the help of equipment from the Special Malaysia Disaster Assistance and Rescue Team (SMART) to ensure the safety of SAR personnel.

Based on observation and inspection at the scene, the department found the location of the landslide to be at the concave slope which easily collected water.

“But, we have not ruled out the possibility of follow-up landslides in the area due to the soil structure and there is still water flowing that can cause landslide.

“We have also advised the rescue team to stop operation immediately if it rains as it could cause another landslide.”

He said the department was assisting the rescue team in the SAR operation and did not rule out the possibility of it conducting further investigation to determine the actual cause of the landslide.

“We hope for fine weather and no rain so that the SAR operation can continue until all victims are found,” he said.

The tragedy occurred following heavy rain in the state since Thursday afternoon until noon the following day, causing the landslide at the container and kongsi area at the Bukit Kukus paired road construction site.

Two bodies were recovered on Friday, that of Indonesian national Samsul Asman, 19, and Bangadesh worker Attrul, 35, while the bodies of Myanmar woman Khin Aye Khaing, 33, and Indonesian Bahtiar, 36, were recovered yesterday at 1.30am and 11.55 am,  respectively. – Bernama

 Checks show projects did not follow SOP 


GEORGE TOWN: As the search and rescue operation for seven buried foreign workers at a construction site in Paya Terubong is going on, shocking information has surfaced that not a single construction site in Penang is following the soil erosion mitigation plan stipulated in their project approvals.

The Star has learnt that the state government has launched Ops Lumpur shortly after the general election, requiring enforcement officers from the local councils to inspect and report on every construction site in all five districts in the state.

A consultant civil engineer familiar with Ops Lumpur claimed that every single construction project did not observe the soil erosion mitigation plan.

He said Ops Lumpur was overseen directly by state exco members and enforcement officers were required to visit the sites.

"Their reports shocked the state exco members. Every contractor failed to do soil erosion measures in every site.

“Now you know why streams near construction site are always yellow when it rains,” he said.

The consultant engineer said the state went after developers who claimed they were not aware and blamed the contractors.

“Civil engineers are often disgusted when they do site visits because it is common for us to see that the soil erosion mitigation plans are never followed,” he said.

The consultant said it was easy to inspect construction sites and check on the progress and questioned whether state government agencies regularly conducted scheduled and surprise visits.

“How often do they conduct spot checks? How strictly do they conduct enforcement rounds on construction sites? If we keep contractors on their toes all the time, we might not have so many landslides,” he said, referring to the latest landslide in Bukit Kukus, the site of a hillside highway from Paya Terubong to Bukit Jambul is being built.

A teh tarik-coloured stream was observed flowing between Jalan Paya Terubong and the barred entrance to the highway construction site yesterday.

It has been raining almost every day in Penang this week.

In yesterday’s incident, rescue team found one survivor and two dead bodies. At press time, seven are still missing.

The Fire and Rescue Department received a distress call about the landslide at 1.56pm.

An Indonesian worker who only wished to be known as Endo, 36, said three of his relatives from Sulawesi were trapped in the landslide and he was working in another nearby construction site.

“It rained all night (Thursday). The rain stopped at 9am (yesterday) and resumed at 1pm. At my site, all of us stayed in our quarters and didn’t work because of the rain.

“I got a call from others that my relatives are missing. So, now I’ll just wait,” he said.

Last Thursday, 14 concrete beams measuring 25m long each, crashed down from an elevated section of the highway.

No injuries were reported and a stop-work order was issued pending investigations of the collapse.

Chief Minister Chow Kon Yeow, who visited the site with several state exco members, said he reminded rescue workers to be wary while searching for the missing victims because the rain could have rendered the slopes unstable.

“All work has stopped here and the contractor was about to send in its report on the collapse of the concrete beams on Oct 11,” he said, adding that the place where the beams collapsed was far from the landslide. - The Star by arnold lohlo tern chern

Water from stream identified as main cause of landslide


GEORGE TOWN: Water flow from a stream on the hilly area in Jalan Bukit Kukus, Paya Terubong, near here has been identified as among the cause of the landslide.

Azhari Ahmad, who is Mineral and Geoscience Department (JMG) director for Perlis, Kedah and Penang, said the finding was made based on its inspection and monitoring since Saturday.

“The JMG team identified several factors that caused the landslide, resulting in all containers on the hill slope to slide down with the earth.

“The main factor that caused the landslide is the water flow from a stream near the slope and heavy rain since Friday morning caused the water to overflow,” he told reporters yesterday.

Azhari said the department had taken immediate measure by diverting the flow of water from the stream elsewhere to avoid worsening the situation, especially during the search and rescue (SAR) operation.

Penang Forum calls to review Penang mega projects

Penang Forum members paying a courtesy call on Chow, seated at the head of the table, at his office in Komtar.

Revise transport master plan because circumstances have changed

" A new public transport design has to be integrated to encourage walking, cycling and bus uise - Penang Forum"


THE Penang Forum steering committee, a loose coalition of non-political civil society groups, has called on the Pakatan Harapan Penang government to review the Penang Transport Master Plan (PTMP) estimated to cost RM46bil.

It said the Penang government should bear in mind its election manifesto of balancing economic growth with environmental protection and a commitment to improve public transport.

"Given the scale of the funding for this mega project, the state must ensure government procurement produces the best value for taxpayers’ money.

“The awarding process used was based on a Request for Proposal, rather than a true open tender, which did not allow for any meaningful comparison of bid documents as the scope of work was not fixed.

“Hence the award process must also be reviewed and revisited,” the statement read.

The committee also pointed out that the present PTMP was based on the assumption that buses, ferries and a cross-channel bridge were under federal control and there was nothing much the state could do.

“So it did not focus on how these could be improved or expanded. But now that circumstances have changed, the plan needs to be revised,” it said.

The committee also said the planning for equitable public transport should take into consideration the following criteria:
  • Fiscal prudence that should consider cost-effectiveness in construction, operation and maintenance.Detailed financial analysis of different public transport systems must be done and compared. The most cost-effective system should be selected.
  • Other important considerations are efficiency of operation, predictable schedules and systems compatibility.
  • The different components of the transport system must be well connected and integrated, socially inclusive, with a low impact on the built and natural environment.
  • Extensive public consultation at every stage, with plans available for online viewing and download so that more people can view and comment. It must be carried out and the exercise must be open to scrutiny.
  • Independent consultants who are at the forefront of designing equitable, sustainable transport must be engaged to do the review of the plans. They must not be associated with or employed by parties involved in tendering for the project.
The statement also read that the 2016 transport proposal was a mega project put forward by SRS Consortium, the project delivery partner of PTMP, to the Penang government.

“The design and planning fails to meet most of the above criteria.

“The overpriced package includes many components of mega road building that will discourage people from using public transport and undermine the stated goal of increasing public modal share of transport.

“Although public consultations have been held about impacts in specific localities, open scrutiny of the whole design was strongly discouraged,” the statement said.

The committee also said the original PTMP by Halcrow involved public consultation, but the state pressured the consultants to add the undersea tunnel and three highways costing a total of RM6.3bil just before it adopted the plan in 2013.

The SRS proposal costing RM46bil includes a proposal to reclaim 4,500 acres of land (comprising three islands). It departs drastically from the officially adopted 2013 Halcrow masterplan.

“Thus, a thorough, proper and independent review should be carried out to ascertain its suitability, viability and sustainability.

“The massive proposed reclamation will destroy fishing grounds and jeopardise fishing livelihoods and a vital local source of seafood. “It will be environmentally unsustainable due to expensive maintenance costs required for dredging in the future.

“Promise 10 of the Pakatan manifesto talks of ensuring food security and protecting the welfare of farmers and fishermen.

“Last but not the least, with rapid changes in public transport technology and new trends in info-mobility, it is imperative that any existing plan for public transport should be re-examined.

“A new public transport design has to be integrated to encourage walking, cycling and bus use,” it said.

Chief Minister Chow Kon Yeow was earlier reported saying that the state government would leave the decision to review the components of the PTMP to the Federal Government.

He said this was because the proposal was at the Federal level right now, adding that if there was any need to review the project, the Federal Government could make a decision. He also said the SRS Consortium would be happy to supply the Federal agencies with additional details. - Starmetro

Geotechnical engineer Aziz Noor says the new project puts the people and the place in danger

Engineer: Lives at risk in Penang hill project


GEORGE TOWN: The DAP-led state government has turned a blind eye on the imminent danger of hill slope development, said a Tanjung Bungah resident.

At a forum-cum-press conference yesterday, geotechnical consultant Aziz Noor (pic) said building the proposed multi-storey mixed development behind the Miami Green Resort Condominium would pose a danger to the condo and its residents.

The development which has been approved on the class four hill, comprises five 29-storey building blocks, two 34-storey serviced apartments with 336 units each and one block of affordable apartments with 197 units.

Meanwhile, former Bukit Bendera MP Zairil Khir Johari, who is the Tanjong Bungah candidate for Pakatan Harapan, said the state government would review the guidelines on hill slope development. – Bernama


GEORGE TOWN: An engineer has sounded a warning about “imminent danger” from a new hillside development of eight tower blocks of apartments planned in an environmentally-sensitive area of Tanjung Bungah.

Geotechnical consultant Aziz Noor, speaking at a forum-cum-press conference today, accused the DAP-led state government of turning a blind eye on the imminent danger of hill slope development.

The proposed mixed development behind Miami Green Resort condominium puts the existing residence and its people in danger, he said.

The development has been approved on a 12-acre plot with a 35-degree slope on a Class Four hill, which exceeds 250 feet above sea level.

It comprises five 29-storey tower blocks, two 34-storey blocks of 336 serviced apartments each, and one block of 197 units of affordable apartments.

Aziz said that the project was not only in an environmentally sensitive area, it also contradicts the 2007 Penang Structure Plan that forbid any development above a gradient of 25-degree gradient and 250 feet above sea-level.

The design of one development does not guarantee safety. A Detailed Environmental Impact Assessment must be conducted and reviewed. This development puts the place and people in imminent danger,” he said.

Residents of the area said they had vented their frustration multiple times since November but had not received any response from the state government and Penang Island City Council.

The residents, together with the Tanjung Bunga residents association, had spoken on the matter many times, but no one seemed bothered, said one of the residents, Lim Liew Ming.

“Our lives are at risk. The upcoming development is a ticking time-bomb. Are the authorities waiting for a tragedy to happen, and only then act on it?,” she asked.

State Barisan Nasional chairman Teng Chang Yeow, who is also BN candidate for the Tanjong Bunga state seat in the general election, said the project should have been shelved from the beginning.

“We will put a stop to this. Even if we need to pay compensation,” he said.

The Barisan Nasional has pledged to declare all highland and hill slope areas of 250 feet above sea-level as permanent forest reserve.

Former Bukit Bendera MP Zairil Khir Johari, who is the Pakatan Harapan candidate for Tanjong Bunga, said the state government would review the guidelines on hill slope development.

GEORGE TOWN: An MCA state leader has criticised Penang Chief Minister Lim Guan Eng over the latter’s statement that more stop-work orders have been issued against hillside development by the current state government.

State MCA Wanita chairman Tan Cheng Liang said Lim, who is also the DAP secretary-general, had “conveniently avoided” revealing the increase in number of protests in the state since 2008.

“He boasts about more stop-work orders being issued now compared to when Barisan Nasional was helming the state government.

“However, he failed to reveal that there have been more protests by Penangites against hillside development since Pakatan Rakyat took over.

“The latest is the chorus of dissatisfaction by residents of Mount Pleasure in Batu Ferringhi, objecting against approval accorded by the Penang Municipal Council (MPPP) for the construction of 21 four-storey villas and 80 two-storey bungalows there,” she said.

She said the 2008 DAP general election manifesto unveiled by Lim promised to “preserve our forest, wetlands and bio-diversity” while Pakatan Rakyat’s common policy framework stressed that the “environment must be preserved for the sustainability of future generations.”

“Just six weeks ago, Lim said in a speech that the Pakatan government was proud of its record of not approving any hillside development.

“However, the voices of disapproval by Penangites are evidence that Lim, the DAP and Pakatan are deceptive,” she claimed.

Citing examples, she said on April 8 this year, Sungai Ara residents protested against approval issued by MPPP Planning Department for two hillside development projects and in February 2009, Tanjung Bungah residents protested and submitted a memorandum calling on the state government to ban all current and future Class III and Class IV hillslope development projects.

“In view of these protests and to deliver the DAP and Pakatan’s pledge to protect the environment, I challenge Lim and the state government to issue a stop-work orders against all hillside development projects approved by MPPP,” she said in a press release yesterday.

Tan also took a swipe at Lim for focusing on luxury residences but allegedly had no regard for the poor.

“Approvals are given for exclusive housing and condominium projects on hills, but scant attention is given to low-cost housing for the poor where no low or medium cost units were constructed between 2008 to 2011,” she claimed.

On Tuesday, Lim said more stop-work orders had been issued by both local councils since 2008 compared to previously.

He said this proved that the state government was “more stringent in upholding the rule of law, demanding strict compliance with technical requirements and more unforgiving than Barisan.” - The Star

Absorb New ways to prevent floods

Sponge City: Solutions for China's Thirsty & Flooded cities

 China's 'sponge city' projects may be worthwhile examples for Malaysia.


"Only about 20~30% of rainwater infiltrates the ground in urban areas, so it breaks the naturual water circulation.- Wen Mei Dubbelaar"

Last week, it was the turn of Petaling Jaya, Gombak and Sungai Buloh to be the latest major urban areas in Malaysia to suffer flash floods (Flash floods wreak havoc in PJ - Nation). Scenes of cars and buildings submerged in muddy water are now almost an everyday thing. The focus should now shift from the bad situations to the solutions.

It was also last week that I attended a briefing organised by civil society groups for Penang and Seberang Perai municipal officials and members. The briefing was on the recent floods.

Later, I came across several articles on how China is turning 30 of its flood-prone areas into “sponge cities” to prevent floods and retain rainwater.

The Chinese plan big and fast. It launched the sponge city project only in 2015, but it aims to retain 70% of rain in 80% of urban areas by 2020. The sponge concept is set to spread rapidly as part of global efforts to reduce the impact of increased rainfall and floods, and climate change.

The concept figured prominently at the briefing chaired by Penang state exco member Chow Kon Yeow. Scientist Dr Kam Suan Pheng introduced it when explaining the floods.

She contrasted the present situation when rain falls with what used to happen. In the past, 50% of the rain seeped through the natural ground cover (trees, grass, etc) and into the ground. There was 10% water runoff (to rivers and drains) and 40% evapotranspiration (water going back to the atmosphere).

The trees and green spaces act as a sponge to absorb the rainwater that infiltrates the soil, preventing the water from building up into flash floods.

Due to urbanisation, the green spaces have been paved over with cement and concrete. Now, only 15% of the rain infiltrates the soil, while the runoff has increased to 55% and evapotranspiration is 30%. The sponge now absorbs 15% of the rainwater compared to the previous 50%.

Dr Kam quoted former Penang Water Authority general manager Kam U-Tee as saying that the October 2008 Penang floods were caused by conversion of the valleys into “concrete aprons that do not retain water”. As a result, the water immediately flowed into streams, causing flash floods, even with moderate rainfall.

Given this analysis, a key part of tackling the floods is to reverse the loss of the sponge. In recent decades, Malaysia has seen the conversion of a lot of farms, parks, trees and grass areas into concrete jungles of roads, houses, commercial buildings and car parks.

There now has to be high sensitivity to the valuable environmental and economic roles of trees, gardens, fields and grasslands, and parks. The aim of garden cities is not just to be pleasing to the eye but to be a very important part of development as well.

Now comes the role of sponge cities. The world is applauding the Chinese initiative to counter floods and improve water security by building up the natural cover (or sponge) in its cities.

In 2010, landslides during flooding killed 700 in three quarters of China’s provinces. Last year, rains flooded southern China, destroying homes and killing around 60 people.

In 2015, China launched the Sponge City initiative, which now covers 30 cities, including Shanghai, Xiamen and Wuhan. The target: by 2020, 80% of its urban areas will absorb and re-use 70% of rainwater.

The many types of projects include:

  • > Constructing permeable roads that enable water to infiltrate the ground;
  • > Replacing pavements on roads and parks to make them permeable;
  • > Building wetlands to absorb and store rainwater;
  • > Constructing rooftop gardens (for example, 4.3 million square feet in Shanghai);
  • > Plant trees on streets and public squares;
  • > Build community gardens and parks to expand green spaces; and
  • > Build manmade lakes and preserve agricultural land to hold water.

“In the natural environment, most precipitation infiltrates the ground or is received by surface water, but this is disrupted when there are large-scale hard pavements,” said Wen Mei Dubbelaar, water management director at China Arcadis, in words similar to Dr Kam’s.

“Now only about 20-30% of rainwater infiltrates the ground in urban areas, so it breaks the natural water circulation and causes water logging and surface water pollution,” said Wen in an interview with The Guardian.

In Shanghai’s Lingang district, the streets are built with permeable pavements. There are rain gardens filled with soil and plants, buildings feature green rooftops and water tanks, and a manmade lake controls water flows, reports The Guardian.

Prof Hui Li at Tongji University said the first thing is to preserve or restore natural waterways as that is the natural way to reduce flooding risk.

The problem in Wuhan is that a lot of small rivers were filled in during building. But Lingang still has agriculture land and a lake to hold more water during heavy rain.

What about the cost factor? So far the cities have received over US$12bil (RM47.4bil) for sponge projects. The central government funds 15-20% of costs, and the rest is from local governments and private developers.

But compare this to the US$100bil (RM395bil) of direct economic losses due to floods in China between 2011 and 2014, plus the human lives lost.

Sponge cities are the way to go for the future. Our own governments – federal, state and municipal – should study this option seriously, as the public braces itself for more floods ahead.
