Officials admit safety fears at Hong Kong-Zhuhai-Macau bridge were investigated a year ago
Problems were not found before graft-busters arrested 21 people last week for allegedly faking concrete test results
May 25, 2017
South China Morning Post Excerpt

Officials have admitted that the government investigated safety concerns over a contractor’s work at one of Hong Kong’s biggest infrastructure projects a year ago, but failed to unearth bigger problems that led to graft-busters arresting 21 people last week for allegedly faking concrete test results.

The government announced on Thursday that it was appointing an independent consultant to conduct tests on concrete used to build the Hong Kong-Zhuhai-Macau Bridge over the next month, while giving a public assurance that the city’s section of the long-delayed and overbudget mega project would be finished on time by the end of the year.

“We have started the test using a gun-like device to detect the strength of the concrete and there is no problem in the results,” Undersecretary for Transport and Housing Yau Shing-mu said. “The rest of the work will be carried out on schedule and according to plan.”

The government admitted the quality of concrete used may have been compromised and Director of Highways Daniel Chung Kum-wah said that to further ensure safety an independent organisation would be recruited to do another round of tests.

Yau added that preliminary inspections “by sight” had found no problem in the bridge’s structural safety.

Opinions split on concrete tests for bridge
The Standard Excerpt
May 29, 2017

Civil engineering professionals differ on whether testing the concrete's strength on the surface of the Hong Kong-Zhuhai- Macao Bridge is sufficient to ensure the mega-project's safety.

The government announced last week that checks of the HK$110 billion project include visual inspections and a non-destructive Schmidt hammer test at critical points of the bridge.

This came after Jacobs China laboratory staff allegedly falsified concrete test reports by changing the date and replacing the material.

Speaking at RTHK's City Forum yesterday, former Hong Kong Institution of Engineers president Greg Wong Chak-yan said he agrees with the government's handling, and that work to review the project should be conducted step by step.

Testing concrete strength with a Schmidt hammer is a recognized method, Wong said, adding the fast non-destructive test allows a large amount of data to be collected within a short period.

It is time-consuming to take samples from the core of concrete structures with the procedures complex, Wong said. He said this should only come after irregularities are found during the Schmidt test.

Raymond Chan Kin-shek, former director of civil engineering and development, said: "The bridge is newly built and there is no sign showing it's problematic."

Chan doubted such a bridge should be drilled with thousands of holes. He said the fact that the laboratory allegedly ran afoul of rules guiding concrete tests does not mean the safety of the bridge is compromised.

But Tommy Lo Yiu, president of the Hong Kong Institution of Certified Auditors, said a small amount of concrete samples should be taken from the cores.

This will allow comparisons with the Schmidt hammer test, creating benchmark figures, Lo said.

Mainland Chinese contractor cited in graft case linked to Hong Kong-Zhuhai-Macau bridge
Foreman for firm involved in bridge project was jailed two years ago for offering bribe to overlook substandard rockfill
May 26, 2017
South China Morning Post Excerpt

A mainland contractor that supplied concrete for one of Hong Kong’s biggest infrastructure projects hit by a safety scandal was involved two years ago in a court case over its purchase of substandard rockfill for the multibillion-dollar venture, it has emerged.

The government .on Friday confirmed the role of China Harbour Engineering Company in the construction of the Hong Kong-Zhuhai-Macau Bridge following the arrest of 21 employees of contractor Jacobs China by graft-busters last week.

They are accused of faking concrete test results for the project by altering time stamps and switching samples.

US firm banned from bidding for Hong Kong contracts for one year following bridge arrests
Development Bureau says Jacobs China’s performance in running laboratory responsible for compliance tests of bridge’s construction materials was ‘unacceptable’
June 3, 2017
South China Morning Post Excerpt

A US engineering firm, some of whose staff have been accused of tampering with quality test results for the bridge linking Hong Kong to Zhuhai and Macau, has been banned from bidding for government consultancy contracts for one year.

The Development Bureau said on Friday that Jacobs China’s performance in running a laboratory responsible for compliance tests of the bridge’s construction materials was “unacceptable”.

But existing government contracts linked to the firm will not be suspended.

In a shocking revelation last week, the Independent Commission Against Corruption arrested 21 employees of Jacobs China, who were accused of faking concrete test results for the mega project by altering time stamps and switching samples.

The consultancy firm is part of US-based Jacobs Engineering Group, which employs 54,000 people worldwide and netted US$10.9 billion last year.

More than a week after the scandal broke, the Civil Engineering and Development Department decided to bar Jacobs China from tendering for any architectural and engineering consultancy work handed out by its selection boards for one year.

The ban will be lifted after June 1, 2018.

As for consultancy contracts signed before the suspension period, “the tender assessment panels of government departments concerned shall, in accordance with relevant guidelines of the works technical circular, assess Jacobs’ tenders in detail and seriously consider whether such tenders should be further processed,” a government spokesman said.

Plans afoot to allow passengers direct travel from Zhuhai to Hong Kong airport across mega bridge
Parcel of land set aside on artificial island off Zhuhai for Airport Authority to set up passenger check-in and ticketing facilities, including coach service
July 6, 2017
South China Morning Post Excerpt

Plans to allow travellers to check in and take a shuttle bus across the mega bridge from Zhuhai directly to Hong Kong’s airport are gathering pace, the Post understands.

A parcel of land has been reserved by the Zhuhai government on an artificial island off the mainland city for the Hong Kong Airport Authority to use.

This would pave the way for the setting up of passenger check-in and ticketing facilities for Hong Kong International Airport (HKIA) on Zhuhai’s offshore island, a source familiar with the matter said.

The facilities would also increase the prospects of a viable shuttle bus service being operated for transit passengers across the bridge.

Completion of the Hong Kong section of the bridge project has been delayed for a year until the end of this year.

The arrangement comes as the Pearl River Delta becomes the focus of Beijing’s Greater Bay Area development plan, bringing together Hong Kong, Macau and nine cities in Guangdong.

Coupled with the enhanced transport links, the bridge and coach service would attract more air travellers from the west of the Pearl River Delta, further raising Hong Kong’s competitiveness against airports in Guangzhou and Shenzhen.

An aviation insider, who was not authorised to speak on the matter but had knowledge of Zhuhai plans to integrate the airport and the bridge, said: “Inside the customs, immigration and quarantine building on the Zhuhai offshore island, they have already left space for HKIA to do check-in and ticketing and develop a bonded coach service.”

The coaches could park next to the airport’s ferry terminal and use existing facilities to move people into the restricted area of the airport.

South China Morning Post Excerpt

Hong Kong’s graft-buster has arrested 21 members of a contractor who are thought to have faked concrete test reports used for the multibillion-dollar bridge project linking the city to Zhuhai and Macau.

Officers from the Independent Commission Against Corruption (ICAC) mounted an operation code-named “Greenfield” last Tuesday and arrested two senior executives, two senior site laboratory technicians, 12 site laboratory technicians and five laboratory assistants from the contractor, which was working for the Civil Engineering and Development Department (CEDD).

They were released on bail pending further enquiries.

An expert warned that, in the worst case scenario, the government may need to reconstruct the bridge columns and further delay the construction, if the concrete used was far below standard.

The development minister, Eric Ma Siu-cheung, pledged that the government would examine the safety of the bridge construction in the wake of the arrests.

It is understood the department had been working with the contractor since January 2013 to conduct compression tests on concrete samples for the Hong Kong-Zhuhai-Macau bridge project. All concrete samples were required to pass the tests within a set period of time.

“It was revealed that when some of the tests were not conducted within the set time frame in compliance with the contract requirements, the site laboratory technicians and laboratory assistants might have adjusted the times on the testing machines to cover up the irregularities,” the anti-corruption agency said in a statement on Tuesday.

Ma said the officials would follow the matter closely and review the bridge construction to see if any improvements were needed.

“If the situation is not that serious, reviewing the existing construction is already enough. Otherwise we will take serious measures and follow up actions. But I do not have any information in hands now,” Ma said.

ICAC’s investigation further revealed some laboratory staff may have replaced the concrete samples to falsify the tests.

“It was suspected that the above malpractice might have started in early 2015. ICAC enquiries [also] revealed that the two senior site laboratory technicians had certified the false test reports. It was suspected that they might have corruptly connived at the submission of the false reports to the CEDD,” the statement continued.
This really undermines the project...why would anyone take that risk for a little extra profit?

HKZMB RAISES MANY ENVIRONMENTAL QUESTIONS, AUTHORITIES ANSWER NONE
Macau Daily Times Excerpt
July 20, 2017

The Hong Kong-Zhuhai-Macau Bridge (HKZMB), almost ready to open, has been widely regarded as a “strong development factor” for the entire Pearl River Delta area and especially for the three cities connected by its branches.

The 34 years between the birth of the idea of building the HKZMB and its final completion have seen many high-profile figures praise the mega-structure and highlight its numerous economic advantages.

Since its construction began in late 2009, questions have been asked more and more frequently about the extent of the infrastructure’s purported advantages and also regarding the possible environmental consequences of such a large-scale project in nearby waters.

Recently, a conservation group in the neighboring region of Hong Kong called for the creation of a supersized marine park to connect all the existing facilities around Lantau Island in order to stop what they described as a “rapid decline in the population of Chinese white dolphins.”

The group, the Dolphin Conservation Society, is also calling for the diversion of high-speed ferries in the estuary area because of the same ecological concerns, according to the South China Morning Post.

The conservation bells first started ringing after the latest white dolphin headcount, conducted by the Hong Kong Agriculture, Fisheries and Conservation Department. A recent report released by the department showed that the number of these marine mammals in Hong Kong waters has almost halved since 2010, reaching a historical low of 47.

The group attributes this decline to the large-scale infrastructure works around Lantau. These include the HKZMB, the building of the city’s third airport runway and the growing frequency of high-speed ferries and other maritime traffic.

This issue is accompanied by several other environmental and ecological challenges posed by the bridge, but the governments of the three impacted regions appear to have little to say on the matter.

An Environmental Impact Assessment study conducted in 2003 by Hong Kong’s Highway Department highlighted the infrastructure’s impact in several key areas: ecology, water quality, air quality and cultural heritage.

“It is anticipated that surrounding [areas] could be affected by noise, air quality, ecological, water quality, visual, waste and cultural heritage impacts during the construction and operational stages,” the department noted in the report.

Regarding ecological concerns, the report warned that “construction at the bridge-land interface and the construction of piers in west Lantau and the Airport Channel may result in increased release of sediments that could potentially affect the mangroves and seagrass communities at/near the San Tau SSSI, [and also affect the] intertidal mudflats and horseshoe crab nursery area in Tung Chung Bay and the habitat of the Chinese White Dolphins.”

Meanwhile, Macau authorities have not publicized the findings from any preliminary studies or made clear their considerations of the possible negative outcomes of the HKZMB.
