FRUSTRATED by the never-ending flood problems in Penang, a group has got together to arrange a meeting with state representatives on Oct 29.

The group of 24 residents associations and management corporations believes that the blame game between Barisan Nasional and Pakatan Harapan politicians should be stopped as the floods have caused a lot of hardship to the people.

Spokesperson Meenakshi Raman said the group would have experts share data collected on floods in their respective areas at the briefing.

“We want to make a collective call to the state government to take the flood and hill erosion issues very seriously,” she said at a press conference at the Consumers Association of Penang in Jalan Masjid Negeri yesterday.

Meenakshi said the state representatives could use the data gathered at the briefing titled ‘Penang Flood: Call for Action’ and discuss the matter during the upcoming state assembly in November.

The briefing is open to the public and the venue and time will be announced later.

“Flood mitigation alone is inadequate. We want comprehensive action and a stop to unsafe overdevelopment at hill slopes,” said Meenakshi.

Representatives of residents groups from Bandar Baru Ayer Itam attended the press conference to voice their dissatisfaction over the repeated flooding in the township, especially in Lebuhraya Thean Tek, Jalan Thean Tek and Lintang Thean Tek.

The groups are from Tanjung Court Condominium, Desa Delima (Tower Blocks), Sri Impian, Fortune Court, Treasure Ville and Desa Baiduri. Tanjung Court Condominium residents ad-hoc group representative K. Suthakar said Lebuhraya Thean Tek in Bandar Baru Ayer Itam would be badly hit by floods every time there was heavy rain.

“The state government keeps saying that the Federal Government doesn’t give them enough money.

“Will the flooding problems go on for five or 10 more years? How long is this going to continue? We are suffering,” he said.

He urged MPs to attend the briefing as well so that they could bring up the flood issue in Parliament.

Later, the group showed photos of landslides that happened during the Sept 15 flooding at Fettes Park, Solok Tembaga and Sungai Ara.

They urged Chief Minister Lim Guan Eng to focus on resolving the flood issues.

Penang Opposition leader Datuk Jahara Hamid said it was a good initiative to hold the briefing as there was a need to better understand the concerns of the people.

“I can only confirm attendance after the venue and time have been fixed,” she said.

Meanwhile, PKR Penanti assemblyman Dr Norlela Ariffin said she would attend the briefing.

Structural defects to blame, stop history repeating itself !

https://youtu.be/7FRTMX53TLc

Sniffing out signs of life: The K-9 unit of the City Fire and Rescue operations looking for possible victims at the site of the bridge collapse near Kampung Haji Abdullah Hukum in Kuala Lumpur.

KUALA LUMPUR: Structural failure possibly caused the collapse of an under-construction pedestrian bridge at KL Eco City near Kampung Haji Abdullah Hukum here.

Department of Occupational Safety and Health (DOSH) director-general Datuk Mohtar Musri said the initial investigation suggested that a defective structure could have led to the disaster on Wednesday.

He said the department would refer to the Construction Industry Development Board (CIDB) and Kuala Lumpur City Hall regarding the quality of materials used in the construction of the bridge.

Works Minister Datuk Seri Fadillah Yusof said a task force has been set up to probe the incident.

He said the result of the investigation was expected to be made public in a month, and that tough action could be taken against the developer if it was found to have flouted safety regulations.

“We can bring them to court, not just under DOSH but CIDB too. Under the CIDB Malaysia Act 1994, they can face a RM500,000 fine or a two-year jail sentence,” he said.

The RM7mil pedestrian bridge linking the planned KL Eco City project to the Gardens Shopping Mall in Mid Valley, which was still under construction, collapsed and killed one worker and injured five others on Wednesday.

The search-and-rescue operation at the site of the incident was halted after it was confirmed that there was no worker trapped underneath the mangled brick-and-iron structure.

City Fire and Rescue Department deputy operations chief Ruhisha Haris said K-9 teams had confirmed that there were no signs of a body.

However, the mystery of the missing construction worker remains.

“We first received information that a worker might have been trapped because a colleague saw him under the bridge minutes before it collapsed.

“A head count by the developer also revealed a missing worker, but they were unable to give us a name,” he said.

The dead victim has been identified as Tran Xuan Vang, 21, from Vietnam. Two other Vietnamese, Tran Van Hai and Luong Van Guyet, as well as Indonesian Nor Syamsi, Bangladeshi MD Jashim and Pakistan national Rais Aman Majid were injured and are currently being treated at Universiti Malaya Medical Centre.

Medical staff were forced to amputate Rais’ left leg on site to save his life.

In a statement issued on the day of the incident, SP Setia, the developer of the project, said it deeply regretted the incident and was working with the authorities in the investigation.

“The project team is still assessing the situation,” it said.

Work on the KL Eco City project – a mixed development comprising three residential towers, one serviced apartments tower, three corporate office towers, 12 boutique office blocks and one retail podium – started in 2011 and is scheduled to be fully completed by 2023.

Commenting on the incident, National Institute of Occupational Safety and Health chairman Tan Sri Lee Lam Thye said the time had come for players in the construction industry to practise their commitment to safety.

“All these accidents are preventable if the person in charge puts into practice good occupational and safety health measures and the site safety supervisor makes sure work is done properly,” he said.

Stop history repeating itself


THE Consumers’ Association of Penang (CAP) is horrified with the news of the collapse of the incomplete pedestrian bridge meant to connect KL Eco City and Mid Valley Megamall in Bangsar, Kuala Lumpur.

Not even a month after a couple was crushed by a piling rig that fell on them at a construction site along Persiaran Astana, Klang, another tragic incident leading to serious injury and death has occurred.

If all the parties involved in the building industry – including the local councils, developers, contractors, architects, quantity surveyors, structural engineers, DOSH and all the others – had carried out their roles and functions efficiently, this could have been prevented.

Despite our repeated calls for the Government to conduct a full inquiry into the operations of the Department of Safety and Health (DOSH), it would seem like the relevant authorities are unable to comprehend the gravity of the situation.

When incidents like this happen, it becomes clear to us that DOSH and developers do not have their priorities right.

Instead of working on preventing such incidents, they wait until it happens before scrambling to take corrective measures to fix the problem.

The issue here is that there are no corrective measures that can be taken once a life is lost; that is not something that can be recovered.

Universiti Sains Malaysia’s (USM) Professor Datuk Dr Mahyuddin Ramli has been reported saying that incidents of this nature can happen when contractors do not comply with safety standards.

In this case, he said that concrete takes at least a week to dry and harden; the wet weather we have been experiencing means it will take even longer.

The USM professor also said that another way something like this can happen is if contractors do not use proper scaffolding during the construction process.

The distance between scaffolds and the size of the scaffolds used are very important as they will vary according to the structure they are meant to hold up.

DOSH’s director-general, Datuk Mohtar Musri, has stated that their initial investigation suggested that the incident happened because the structure was defective.

He said that they need to look into the quality of the materials that were used to construct the pedestrian bridge.

Whatever the cause, the relevant authorities and the public need to be aware that this is just history repeating itself.

If the incident did truly happen because of a structural defect, then it needs to be made clear that nobody can plead ignorance.

DOSH safety officers and onsite safety inspectors should have known about the structural defects if they did exist.

This begs the question of whether or not proper safety inspections were done at the appropriate stages by the relevant parties.

We ask that the results of the investigation into the latest incident be shared with the general public.

CAP would also like to know what happened to the findings from the investigation of previous incidents.

Why has this information not been shared with the public when their lives are also put in danger by the conduct of those at construction sites?

In view of this, CAP calls for penal action to be taken against all parties who have been involved in the project. They should all be held accountable even if they were not directly involved.

Worker killed in bridge collapse tragedy


https://youtu.be/3QFRF_5oRAY

The Star Graphics:  http://clips.thestar.com.my.s3.amazonaws.com/Interactive/midvalley/midvalley.mp4

KUALA LUMPUR: A Vietnamese construction worker was killed and five others were injured when a 70m yet-to-be-completed bridge near Jalan Kampung Haji Abdullah Hukum and Mid Valley Megamall collapsed.

The victim was buried in the rubble of the collapsed pedestrian bridge.

As of press time, rescue workers were still searching for a Bangladeshi worker believed to be trapped in the rubble.

The authorities have since mobilised the K9 unit to locate him.

The firemen and paramedics were seen changing shift as the rescue mission continued into the night. Some were heard saying that locating the victim would be challenging.

However, all the rescuers were resolute in their attempt to find the last victim, never once giving up hope.

The five injured workers – two Vietnamese, two Bangladeshis and an Indonesian – were sent to the Universiti Malaya Medical Centre for treatment.

Brickfields OCPD Asst Comm Sharul Othman Mansor said the bridge was 80% completed when the incident occurred.

“We are still investigating the incident.

“We were alerted at about 4pm of the incident and quickly mobilised a search-and-rescue team,” he said at the scene.

Four roads were also affected by massive jams due to the incident.

According to Star Media Radio Traffic, the affected roads were the Federal Highway from the arch, the Kerinchi Link after the Pantai toll plaza, Kerinchi Intersection from Bangsar South or Pantai Medical Centre and Jalan Syed Putra from the Kuen Cheng School till the Robson Intersection.

While the main reason for the traffic congestion was due to certain road closures to make way for rescue workers, traffic was backed up near the mall due to many motorists slowing down to see the collapsed bridge.

Mall patrons, construction workers and curious onlookers were seen crowding the area near the bridge, where it was cordoned off for safety precautions.

Govt may handle workplace safety


Fadillah: Independent monitoring likely


KUALA LUMPUR: The Government would like to take over the job of monitoring safety at construction sites away from developers following a string of deaths as a result of mishaps in the last three months.

Those duties, said Works Minister Datuk Seri Fadillah Yusof, may be entrusted to third party organisations that will be given autonomy in the planning, execution and supervision of workplace safety at construction sites.

Usually, these jobs are handled by contractors hired by the project developers but Fadillah said that this would mean the monitoring process was not independent.

Speaking at the launch of the Sustainable Construction Excellence Centre (Mampan), the minister said the suggestion for independent monitoring was brought up by the experts at the centre.

Mampan is headed by the Construction Research Institute of Malaysia (Cream), a subsidiary of the Government’s Construction Industry Development Board (CIDB).

Fadillah said the proposal to appoint third party safety monitors would be implemented first in Government construction projects.

He added that he hoped the private sector construction industry would do the same.

Currently, the Department of Occupational and Safety Hazard (DOSH) monitors government projects but it is reportedly too understaffed to keep track of every project.

For now we will have to make do with existing laws. This is why we need a commitment from the industry players,” he told reporters after the launch.

For now we will have to make do with existing laws. This is why we need a commitment from the industry players. Datuk Seri Fadillah Yusof

He said that Mampan would be a key organisation under the Government’s environmental sustainability initiative for its Construction Industry Transformation Programme.

The centre will undertake research with Universiti Teknologi Malaysia, Universiti Kebangsaan Malaysia, Universiti Sains Malaysia and the Rehda Institute to instil better industry practices, certification and awareness in the construction industry.

“We don’t want to build bridges that have no resilience and collapse when there is a flood.

“Our short-term goal is to position Malaysia as a regional leader in sustainability in construction and to raise the perception of sustainability in construction here,” he said.

Fadillah witnessed the signing of a Memorandum of Understanding between Cream chairman Tan Sri Dr Ahmad Tajuddin Ali and academics from the four universities and research institutes which will be a part of the new centre.

Save Penang Hill from the greedy

Uphill battle: A hiker passing by a vegetable farm on Penang Hill overlooking Air Itam.


Treasured heritage seems to be losing its charm to illegal farms and development

THE stall at the Air Itam market in Penang is said to offer the best asam laksa in Malaysia.

Rain or shine, it pulls in the crowd.

The ingredients for the dish such as ginger bud (bunga kantan), mint leaves (daun pudina), laksa leaves (daun kesum) and kalamansi limes (limau kasturi) come from Penang Hill, which is less than 200m away.

Farmers who cultivate the land at the hillslope sell their produce at the wet markets on the island.

The fertile hillslope from Air Itam to Paya Terubong is cultivated with vegetables and fruits.

Demand for the produce is so great that farmers are illegally clearing the hillslope to expand their farms.

About 2km from the market along Jalan Paya Terubong, there is a trail leading to a hillslope.

Lately, hikers and mountain bike enthusiasts have been using the trail to reach the 135-year-old Cheng Kon Tse Temple, nestled on the slope of the hill.

Travellers can see vegetable farms and fruit trees on both sides of the trail.

There are nutmeg trees, kalamansi lime trees, papaya and banana trees.

The vegetables include lemon grass, lady fingers and sweet potato.

As one continues walking up, a large swathe of hillslope which had been cleared near the telecommunication towers comes into view.

The bald patch can be seen from the Paya Terubong road below.

The slopes on Penang Hill have been cleared by farmers over the past few decades.

Such illegal hillslope clearing has been raised by environmental groups but there has been no firm action from the authorities.

A former Penang Island City Councillor claimed that he had provided pictures of the clearings to state leaders and that he had also raised the matter with the Consumers Association of Penang and Malaysian Nature Society.

“The press should continue to highlight the issue so that something is done finally,” said the former councillor who did not want to be identified for fear that the farmers might go after him.

“Penang Hill is our heritage. But no one seems to bother,” he said.

Besides Penang Hill, bald patches are also appearing on hills in several parts of the island.

Bukit Relau in Jalan Bukit Gambier has been dubbed “botak hill”.

There is also hill clearance in Bukit Kukus in Paya Terubong and Bukit Laksamana, a water catchment for the Teluk Bahang Dam.

More and more hillslopes are going bald because of developers and contractors who cleared the land without the authorities’ approval.

The clearings are done on weekends and smoke can be seen from far when the trees are burnt.

A large swathe of land has also been cleared at a place referred by hikers as level 45 station.

It should not be difficult to nab the culprits since there are cemented trails all over the hillslopes in Air Itam and Paya Terubong.

When The Star reported on Feb 14 last year that more bald spots could be seen, a state exco member said they had pictures of the illegal activity and that action would be taken against the culprits but till now, no one knows what the action is.

It is troubling that all this is happening under a state government which emphasises on Competency, Accountability and Transparency.

Penang Hill seems to be losing its charm.

Yet, the state government seems to be focused on mega projects and land reclamation.

At a state assembly sitting last month, Chief Minister Lim Guan Eng said the Penang Island City Council was using drones to check on illegal hill clearing and CCTVs would be installed next year to monitor illegal earthworks.

The spate of hill clearings has prompted the Penang Forum, a coalition of public interest NGOs, to hold a forum on Save the Hills of Penang tomorrow.

Hopefully, the outcome from the event will reach the right ears.

There is a compelling need to save the hills from greedy farmers and developers.

Penang flood aftermath: design pump system needed to drain out water, fix funding snag ...

Good plan needed to drain water from flood-hit areas

PENANG’S drainage system is unable to cope with heavy rain falling within a short period of time, said state Local Government, Traffic Management and Flood Mitigation Committee chairman Chow Kon Yeow.

He said the cause of flooding in the state on Sunday night was due to the “very heavy and continuous downpour”.

“In Teluk Kumbar, the occurrence of flash floods can only be remedied by the installation of a more efficient pump system with a higher capacity to drain the water out from the affected area during high tides and rain.

“At the moment, a consultant has already been appointed to come up with the design in a few months for a RM3mil project to upgrade the pump system. Hopefully by the second half of next year, the tender can be called to appoint the contractor to carry out the installation.

“A detailed design is also being drawn up for a RM7.5mil flood mitigation project, approved by the state, in order to upgrade the drainage of Sungai Nipah, Sungai Teluk Kumbar and Sungai Relau,” he said at the launching of the ‘Pedestrian is King’ campaign at Town Hall yesterday.

Chow added that the Irrigation and Drainage Department (DID) had also ordered a developer to clear the clogged drains at its project site in Batu Maung that had allegedly caused a mudslide.

He said the areas affected by the downpour from 7.30pm onwards were Sungai Tiram, Relau, Teluk Kumbar, Bandar Baru Bayan, Kampung Seronok and Batu Maung as well as roads including Jalan Mahsuri, Jalan Tengah and Jalan Sultan Azlan Shah.

“The Sungai Ara catchment also recorded 80mm of rain water in a hour. It would be a different outcome if the 80mm downfall took place over two to three hours, instead of within an hour which made the effect more pronounced,” said Chow.

The categorisation of rainfall intensity exceeding 60mm in one hour is considered very heavy according to the DID.

Bayan Baru MP Sim Tze Tzin urged the state government to immediately implement the southwest district flood mitigation masterplan.

“Developers from southwest district have been contributing to flood mitigation funds. Residents also pay their quit rent diligently.

“It is only fair to start using these drainage contribution funds to upgrade drainage infrastructures within the area,” he said.

Call to fix Penang’s flood funding snag


PENANG will carry improvements on the drainage and irrigation systems if it had the money, said state Local Government, Traffic Management and Flood Mitigation Committee chairman Chow Kon Yeow.

“In the 11th Malaysia Plan, we applied for more than RM800mil worth of projects but none was approved.

“If we have the money, we will, of course, conduct works on Sungai Pinang, Sungai Junjung, Teluk Kumbar and other places,” he told a press conference at 1st Avenue Mall yesterday.

Commenting on the drainage system in the southwest district that was built in the 70s, Chow asked that funds be given so the state could replace the antiquated system.

“Drainage and irrigation is a joint responsibility of the state and the Federal Governments, moreover, the Irrigation and Drainage Department (DID) is a federal agency.”

Meanwhile, state Housing Committee chairman Jagdeep Singh Deo said it was imperative that Sungai Pinang be deepened and widened as scheduled under Phase II of the flood mitigation project.

“The rainy season has started and we need to start work on the second phase as it involves the areas most effected by flood.

“I sent Natural Resources and Environment Minister Datuk Seri Wan Junaidi Tuanku Jaafar a letter dated Dec 1 to ask for the funds for the project (to be released),” Jagdeep, the representative for the constituency, told a press conference.

“The state has done its part and relocated the residents in Sungai Pinang.

“We want the Federal Government to be committed to carry out the RM450mil Sungai Pinang Phase II flood mitigation project.”

Under Phase 1 of the project, the river was widened and deepened from Kampung Rawa to the Dhoby Ghaut bridge.

Phase 2 involves, among others, relocating residents to make way for the project and the rehabilitation of the entire river.

Other flood mitigation projects involve Sungai Juru and its basin (RM80mil) as well as restoration works for Sungai Jawi (RM40mil), Sungai Perai (RM35mil) and their basins.

The projects for Bayan Lepas are estimated to cost RM153mil, Sungai Perai (RM35.4mil) and Sungai Kechil in south Seberang Prai (RM12mil).

Odd job worker Nurjan Md Shabdin, whose house is near Sungai Pinang, said she has experienced flooding as high as chest level during the 50 years that she has lived there.

“There are still snakes and monitor lizards that swim into our houses during the floods. My appliances and mattresses have had to be replaced many times,” she said.

Hammad Noor Abdullah, 41, who has lived there since he was 14, said he had to carry his school uniform in a bag and swim to school when the are was flooded.

“I am hoping the Phase II project is carried out and the village is finally free from floods,” he said.

On a separate matter, Chow said the state government had formed a steering committee and four sub- committees to implement the Penang Transport Master Plan.

“We have the Legal and Finance, Technical, Land Use, and the Strategic Communication committees which I head.”

When asked what the plans were for Eastern & Oriental Bhd’s 131 acres of reclaimed offshore land of Gurney Drive for the STP Phase 2, he said the plans had yet to be finalised.

“Part of it will be given to Ewein Zenith Sdn Bhd and there will be a road, green area, linear park and low-density commercial buildings. It’s just a concept now.”

Chow did not rule out a public consultation on the works should there be a need. Reclamation works on the land is expected to start this month.

Separately, Chief Minister Lim Guan Eng claimed that the Federal Government had sidelined the state.

“Penang has been excluded from the Budget over the years and several projects have also been cancelled.

“The state’s application of RM805mil for flood mitigation projects was rejected and promises to build an LRT system to reduce traffic on the roads have not been fulfilled,” Lim said.

“The request for an upgrade of the Penang International Airport was also not given serious consideration.

“I hope the promise to build a multi-storey car park to increase parking capacity at the airport will not become an empty promise,” Lim said in a press statement.

Coping with flood aftermath


Flood water flowing onto the lane in front of the arrival hall of Penang international Airport in Bayan Lepas.

SPRING-CLEANING was the order of the day throughout Penang due to the extraordinary downpour that lasted more than 10 hours and inundated many areas.
Residents living in Permatang Damar Laut Road felt the full brunt of Mother Nature as their houses were filled with mud after the flood.

About 50 residents held a demonstration, blaming the upgrading works along the road for their plight.

“The project has a poor flood mitigation system. Each time it rains, residents know the area will flood,” said housewife Hasiah Md Isa, 57.

Resident Zulkifli Abdullah, 63, said contractors should dig drains alongside their project.

According to Bayan Baru Umno division chief Datuk Mansor Musa, who was present at the demonstration, the Public Works Department (JKR) is undertaking the project.

“We have contacted JKR along with the contractor in charge of this project, asking them to visit the site and explain the situation. It is important for them to identify the cause of the problem.

“We are now requesting that the contractor pay compensation to the residents affected,” he said.

Kampung Sungai Tiram resident Zaliha Yaacob, 28, said the family spent a sleepless night moving their belongings from the rising water.

“We always expect a flood when it rains but we did not expect it to be this bad,” she said while clearing the mess at her home.

Business owner Lau Kok Peng, 60, was also busy cleaning his popular coffee shop.

“It’s a good thing my shop closes on Monday but there’s a lot of work to do,” he said.

In Teluk Kumbar, 44 flood victims from 12 families have left the evacuation centre for home.

Operations officer Lt Muhammad Aizat Abdul Ghani said flood victims began seeking shelter at the Dewan Perda Kampung Masjid Teluk Kumbar from 8.55pm on Sunday.

“They are from Kampung Sulup, Kampung Nelayan and Kampung Seronok.

“They received sufficient supplies from the Welfare Department during their overnight stay,” he said.

On Sunday evening, heavy rain lashed the island and mainland, inundating several low-lying areas.

Traffic came to a crawl as motorists sought safer routes out of flooded roads.

The state recorded 80mm of rain water in an hour from 7.30pm.

Penang Fire and Rescue operation centre head Y. Anbarasan said rescue personnel, including a boat unit, were dispatched as soon as the first flood distress call was received at 9.32pm.

“At 5.10am (yesterday), we evacuated 37 flood victims from 11 families to Dewan Perda Kampung Masjid Teluk Kumbar.

“There were no landslides but two trees fell in Tasek Gelugor and one in Batu Uban,” he said.

At the Pesta site in Sungai Nibong, ankle-deep water forced some operators to close shop early.

Other flooded areas on the island included Jalan Tengah in Bayan Baru, Bukit Jambul, Relau and Batu Maung.

Penang Island City Council Urban Services Department director Mubarak Junus said about 40 staff members were dispatched to help clean up the mud in affected areas including Permatang Damar Laut, Jalan Kampung Bukit and around the Penang Snake Temple in Bayan Lepas.

“We’ve also deployed backup squads to help clean up the roads and drains, and two teams to help in the garbage collection,” he said.

On the mainland, the worst affected areas were Permatang Tinggi as the river bund there broke, causing water from the river to flow into Kampung Permatang Tinggi, Taman Usaha, Taman Usaha Jaya and Taman Pewira.

Seberang Prai Municipal Council president Datuk Maimunah Mohd Sharif said a special squad and six response teams were dispatched to the affected areas on Sunday night.

“Some of the team members stayed until 1am (yesterday) while some stayed on until 3am to monitor the situation. No residents were evicted,” she said.

She said Seberang Prai district received an average 50mm of rainfall.

The Meteorological Department forecasts cloudy mornings followed by thunderstorms in the afternoons and evenings every day for the entire week until Sunday.

A spokesman from the department said the north-east monsoon would cause the northern region of peninsular Malaysia to receive heavy rainfall late in the day until the end of this month.

Also affected was the Penang International Airport which saw the driveway outside the arrival hall flooded.

When contacted, Penang International Airport senior manager Mohd Ariff Jaafar said there was not much discruption to the airport.

“The prior RM1.5mil flood mitigation project involving the installation of an on-site detention tank helped decrease the water during flash floods.

“There was backflow of water from a monsoon drain for two hours in the evening.

“The volume of water increased to about 69mm at 8pm but the water cleared up in less than 30 minutes,” he said in a text message.

Rainy day for commuters

Long journey home: Cars moving at a snail’s pace along the SPICE indoor stadium in Jalan Tun Dr Awang in Bayan Lepas.

GEORGE TOWN: A torrential downpour which lasted about 90 minutes caused flash floods in several areas in Bayan Baru, Bayan Lepas and Relau near here.

Among the worst affected roads yesterday were stretches of Jalan Sultan Azlan Shah, Jalan Tengah and Jalan Mahsuri.

Many vehicles were stalled in the flood waters which rose to about knee high at some places following the heavy rain which began at about 6.30pm.

The situation was so bad at one point that a stretch of Jalan Sultan Azlan Shah in Bayan Lepas was temporarily closed off to traffic in both directions which worsened the traffic congestion already faced by road users.

Among the places where motorists were caught in traffic jams lasting for more than an hour were Jalan Sultan Azlan Shah and Jalan Tun Dr Awang.

The driveway outside the Penang International Airport’s arrival hall and the roundabout leading to the airport were also flooded, causing vehicles to move at a snail’s pace. Some people could have missed their flights due to the floods and traffic congestion.

The Penang Pesta ground was also hit by the floods. The annual fair began on Saturday.

Penang Works Committee chairman Lim Hock Seng, when contacted, said the rainwater could not flow off quickly enough due to the high volume from the heavy rain.

“The drains are also clogged by rubbish. The Penang Island City Council, Public Works Department and Drainage and Irrigation Department are looking into the matter,” he said.

Among the villages flooded were Kampung Sulup in Teluk Kumbar and Kampung Sungai Tiram in Bayan Lepas where the waters rose up to about 0.6m high.

Kampung Sungai Tiram villager Zaliha Yaakob, 28, urged the authorities to solve the flood woes in the village.

2 structures collapse due to incompetent engineers and irresponsible officer of MPPP


Three slammed over finwall tragedy

GEORGE TOWN: An incompetent engineer, a irresponsible one and a neglectful senior civil servant have come under fire in the report on the collapse of the finwall from the top of the 21-storey Menara Umno building in Jalan Macalister here.

A car driver and a lorry attendant died in the incident on June 13, 2013. Several vehicles and property were damaged. The body of the motorist was never been recovered.

The Commission of Enquiry, headed by Datuk Yeo Yang Poh, recommended that the Board of Engineers take action against finwall design engineer Lee Ah Yew and Dr Gerry Wong Kong Ming who signed and submitted the engineering drawings to the then Penang Municipal Council.

The report stated that (the then) North-East district officer Azizi Zakaria ought to have played a central role as the person in charge of emergency responses under ‘Arahan 20’, but had totally ignored and abandoned his duties.

It said Azizi was unfit to hold his post and “should have the honour of resigning, failing which he should be removed from office.”

Chief Minister Lim Guan Eng distributed copies of the 312-page “Report of The Commission of Enquiry into the Failure of Two Civil Structures in the State of Penang” to pressmen yesterday.

The report also details investigations into the ramp collapse at the Batu Maung Interchange of the second Penang bridge on June 6, 2013.

On the Menara Umno building, the report said the collapse of the finwall was due to “grossly inadequate design.”

The finwall, which was called “a lightning arrester” by the media, is a reinforced-concrete structure weighing about 200 tonnes.

“The engineer Lee has no experience in designing a slender cantilever column on top of a tall building.

“He committed multiple serious errors when designing the structure,” it said.

On Dr Wong, the report said that he signed and submitted the engineering drawings to the council without checking.

“As such, the errors and inadequacies in the design of the finwall are deemed to be his; for which he must bear equal responsibility.”

The report said Azizi’s dereliction of duty was “so complete that it is difficult to imagine anyone who could have done worse”.

“His lack of remorse or contrition when he testified before the Commission and his unabashed downplay of his total neglect of duty are very disturbing,” it said.

Lee and Dr Wong could not be reached for comments. It is learnt that Azizi has retired.

GEORGE TOWN: The Commission of Inquiry into the failures of two civil structures in Penang has come down hard on the engineer who designed the fin wall atop the 21st storey of Menara Umno in Jalan Macalister.

The engineer, Lee Ah Yew, was "grossly incompetent and grossly negligent" and had committed multiple serious errors, which resulted in the reinforced-concrete structure weighing about 200 tonnes collapsing on June 13, 2013.

In its report, the three-member commission headed by Datuk Yeo Yang Poh said Monday that Lee, who designed the fin wall in 1995, was then a graduate engineer with no experience in designing a "slender" cantilever column on top of a tall building.

The commission has recommended that the Board of Engineers (BEM) initiate disciplinary action against Lee.

It said the board should also take disciplinary action against Dr Gerry Wong Kong Ming, the submitting engineer who signed and submitted the engineering drawings to the local planning authorities.

"As such, the errors and inadequacies in the design of the fin wall are deemed to be his; for which he must bear equal responsibility, though he signed them without checking," it said.

The commission rapped the North-East district officer Azizi Zakaria for abandoning his duties as the person in-charge of emergency responses under Arahan 20.

"His dereliction of duty was so complete and that it is difficult to imagine anyone who could have done worse.

"Encik Azizi's lack of remorse and contrition when he testified before the commission and his unabashed downplay of his total neglect of duty, are very much disturbing,” the report stated.

In the incident, the fin wall collapsed and hit a passing car and buried it (together with its driver) beneath the ground. A lorry attendant nearby was also killed. Several vehicles and properties were damaged.

The commission also submitted its findings into the ramp which collapsed on June 6, 2013 at the Batu Maung interchange leading to the second Penang Bridge.

Building structural integrity & failure: problems, inspections, damages, defects, testing, diagnosis, repair

Structural integrity and failure is an aspect of engineering which deals with the ability of a structure to support a designed load (weight, force, etc...) without breaking, tearing apart, or collapsing, and includes the study of breakage that has previously occurred in order to prevent failures in future designs.

Structural integrity is the term used for the performance characteristic applied to a component, a single structure, or a structure consisting of different components. Structural integrity is the ability of an item to hold together under a load, including its own weight, resisting breakage or bending. It assures that the construction will perform its designed function, during reasonable use, for as long as the designed life of the structure. Items are constructed with structural integrity to ensure that catastrophic failure does not occur, which can result in injuries, severe damage, death, or monetary losses.

Structural failure refers to the loss of structural integrity, which is the loss of the load-carrying capacity of a component or member within a structure, or of the structure itself. Structural failure is initiated when the material is stressed beyond its strength limit, thus causing fracture or excessive deformations. In a well-designed system, a localized failure should not cause immediate or even progressive collapse of the entire structure. Ultimate failure strength is one of the limit states that must be accounted for in structural engineering and structural design.

These articles explain the inspection, detection, diagnosis, and repair of all types of structural defects on residential and light commercial buildings and will answer most homeowner concerns. We address brick and other masonry structures, wood frame structures, log homes, modular and factory built homes, even mobile homes.

Chimneys, crawl spaces, decks, building flood damage, foundation crack and movement damage, rot or insect damage, sink holes, and water entry are examples of topics for which InspectAPedia provides inspection, diagnosis, and repair advice. Our page top photo illustrates Story Land[26] a remarkably askew wood-framed structure that would have been quite challenging to frame.

Guide to Detecting & Evaluating Structural Defects: Inspection, Diagnosis, & Repair of Settlement, Improper Construction, Rot & Insect Damage to Buildings


Articles found in this section address just about all types of residential & light commercial building structural construction, inspection, diagnosis & repair topics such as foundation damage, leaning, buckling, bowing, and cracking, FRT plywood failures, chimney inspections & safety concerns, causes and cures for rot, mold, & termites in buildings, sinkholes at building sites, stair and rail fall & trip hazards, & also special inspection methods for mobile homes.

Most structural problems can be avoided by proper design and planning; but structural failures have been common for a long time, and sometimes are costly to handle properly.

This photo of the leaning tower of Pisa was sent to us by our friend Tom Smith who knows a crooked building when he sees one. Smith points out that the problems with the Tower have been known for generations and must have been apparent even during construction, as the upper level was constructed with an offset to try to re-balance the structure.
Modern reinforcement has permitted removal of cables that used to be tied to the tower of Pisa. As Bernie Campbalik says about old buildings, "Yep, we had guys like that back then too."
