Changi Airport awards S$999 million contract for T5 intra-terminal tunnels
[SINGAPORE] Changi Airport Group (CAG) has awarded a S$999 million contract for the construction of intra-terminal tunnels at the upcoming Terminal 5 (T5).
The contract was bagged by a joint venture between Japanese construction firm Penta-Ocean Construction and a subsidiary of Koh Brothers Eco Engineering, a local construction and engineering firm.
The intra-terminal tunnels will serve as underground connections within T5, said CAG in a Tuesday (Jun 10) press statement. This will support the transfer of passengers and baggage across the terminal's concourses while facilitating the routing of common utilities.
The project, which is expected to take more than four years to be completed, will also comprise a ventilation building and provisions for a future underground infrastructure tunnel.
The announcement follows the groundbreaking of T5 in May. CAG estimates that with the completion of the terminal, the airport's annual capacity will grow to 140 million passengers, from the current 90 million.
Its network is also projected to increase from around 170 city links to more than 200 by the mid-2030s.

Koh Brothers Eco's subsidiary to build underground tunnels at Changi's upcoming T5 in S$999M JV deal
Phot: Depositphotos/tang90246 SINGAPORE: Koh Brothers Eco Engineering's subsidiary, Koh Brothers Building & Civil Engineering Contractor (KBCE), has been awarded a S$999 million contract by Changi Airport Group (CAG) to build underground tunnels at Changi Airport's upcoming Terminal 5 (T5). The project will be carried out through a joint venture with Penta-Ocean Construction, according to the company's press release on Tuesday (June 10). KBCE will be in charge of constructing intra-terminal tunnels that link different parts of Terminal 5. The tunnel system will include several sub-tunnels that will house key infrastructure to support airport operations, including the automated people mover system, baggage handling system, and a common services tunnel (CST) for utilities such as electrical power, communication systems, and water services. The works will also include a ventilation building to support the CST, along with provisions for a future underground infrastructure tunnel. Paul Shin, Koh Brothers Eco's CEO, said, 'We are honoured by the trust placed in KBCE and Penta Ocean for this mega project by airport operator Changi Airport Group (CAG). Securing this contract marks our deepened collaboration with CAG and another milestone in our commitment to supporting Singapore's transport infrastructure.' In early May, Changi Airport Group awarded S$4.75 billion in contracts for substructure and airside infrastructure works at T5 . The new terminal, expected to open in the mid-2030s, officially broke ground on May 14, 2025, and will help Changi Airport handle 50 million more passengers each year . /TISG Read also: SATS gears up for Changi Terminal 5 with S$250M in ground and cargo upgrades Featured image by Depositphotos (for illustration purposes only)

Jetstar Asia's exit shrinks options for consumers, but unlikely to dent Changi's hub status
News analysis Jetstar Asia's exit shrinks options for consumers, but unlikely to dent Changi's hub status SINGAPORE – Jetstar Asia's impending exit after more than two decades in Singapore is a blow to budget-conscious travellers, even if the low-cost airline's modest 3 per cent share of Changi Airport's traffic might suggest otherwise. Although Changi remains well-served by other budget carriers on busy routes such as Bali and Jakarta, Jetstar Asia's departure will sever non-stop links to four emerging holiday spots. The Singapore offshoot of Australia's Jetstar – which began operations in December 2004 – is the only airline that serves Okinawa in Japan, Wuxi in China , Labuan Bajo in Indonesia and Broome in Australia from Changi. While Changi Airport Group (CAG) has said it would work with other airlines to restore connectivity , the prospect of losing non-stop connections to these cities comes at a time when Singapore is looking to aggressively expand the number of destinations linked to Changi. The airport is connected to about 170 cities worldwide, and the target is to surpass 200 cities by the mid-2030s, when Terminal 5 opens. Maintaining as many air links as possible is good for airlines and consumers, especially when low fares are in the mix. This also strengthens Changi's competitiveness as a transit hub. Jetstar Asia, which is 49 per cent owned by Australia's Qantas and 51 per cent by Singapore company Westbrook Investments, cited higher airport fees and aviation charges, as well as intensifying competition, as reasons it had become unsustainable to continue operations at Changi. Mr Linus Benjamin Bauer, founder and managing director of aviation consultancy BAA & Partners, said rising costs are squeezing low-cost carriers. 'Many airlines still operate under pre-pandemic pricing models, but face a vastly more expensive cost base,' he said, adding that more exits or mergers, especially among smaller budget airlines, can be expected. The writing had been on the wall for some time for Jetstar Asia. It was the slowest of the three Singapore-based carriers – the others being Singapore Airlines (SIA) and its budget arm Scoot – to rebound from the Covid-19 pandemic. Its fleet of 13 Airbus A320 aircraft is down from 18 before the pandemic. Its move from Changi's Terminal 1 to Terminal 4 in March 2023 – which the airline protested publicly – also lengthened connecting times for passengers transferring to Qantas or its partner airlines. T4 is a distance from T1, where Qantas operates, for instance. When Singapore announced its latest round of airport fee hikes in November 2024 to fund improvements to Changi Airport and defray rising costs , Jetstar Asia had warned the increases would have an impact on its ability to offer low fares. It also noted that most of CAG's planned upgrades do not apply to T4, where it operates. Under the new fee structure, landing, parking and aerobridge charges for narrow-body jets such as the A320 will rise yearly, climbing from about $1,200 per landing before April 2025 to $1,725 in April 2030. Passenger fees will also go up in stages until the end of the decade. Passenger fees at Changi are already steeper than those in regional hubs such as Bangkok. While such costs are seen as necessary to help airports fund infrastructural improvements to meet future demand, the increases have made it increasingly difficult for low-cost carriers such as Jetstar Asia to keep air fares low – their key selling point – without passing the extra costs on to customers. 'Singapore has become a high-cost environment for a low-cost carrier, and Qantas Group and Jetstar feel they can get better returns on their assets in other markets,' said Mr Mayur Patel, Asia head at consultancy OAG Aviation. It does not help that in some cases, full-service carriers such as SIA can also offer low fares if tickets are booked early. This is because they have the flexibility of deploying wide-body or narrow-body aircraft, depending on demand. After its closure, Jetstar Asia's 13 planes will be redeployed progressively across the Qantas Group to support fleet renewal and growth in Australia and New Zealand in line with demand. The low-cost airline's closure comes as global demand for air travel remains strong. Airlines are expected to fly a record 4.99 billion passengers in 2025 – a 4 per cent increase from 2024 – according to the latest forecast from the International Air Transport Association. The Asia-Pacific region is driving this growth. So why has Jetstar Asia struggled to take advantage of this? This has partly to do with the intensity of competition on seven of the 16 routes that it serves, which are operated by at least three other airlines, data compiled by Mr Patel showed. Singapore-Bali is served by nine airlines including Jetstar Asia, Singapore-Jakarta by eight, and Singapore-Kuala Lumpur by seven. Even fellow low-cost carrier AirAsia has scaled back on some routes of late, likely due in part to higher operating costs. It dropped its Singapore-Ipoh and Singapore-Phuket services, and cut back flights to Bangkok's Don Mueang Airport earlier in 2025. Jetstar Asia's exit leaves SIA and Scoot as the only Singapore-based carriers. While consumers will have one less option, choices still abound, with one-fifth of the 100 airlines at Changi being low-cost carriers. Overall, they serve more than half of the 170 cities that the airport is connected to. Mr Patel said any connectivity gaps left by Jetstar Asia's exit can be filled only in the short to medium term by other carriers. This is due to delays in the delivery of new aircraft and the time needed for capacity changes. Ultimately, Jetstar Asia's withdrawal from Singapore will shrink the choices available to consumers, particularly those eyeing the non-stop links it served exclusively. But its limited market share means that the impact on Changi's standing as a hub will likely be minimal. Kenneth Cheng is assistant news editor at The Straits Times.

Chinese carmakers vow to make timely supplier payments as backlash to price war grows
[SHANGHAI] Major Chinese car manufacturers have pledged to make payments to suppliers within 60 days, responding to a recent outcry from steelmakers over long payment times as well as regulatory pressure as the backlash to a punishing price war grows. Chinese authorities issued new rules in March that require big companies to settle most payments with suppliers within 60 days, which became effective June 1. However, suppliers had been worried that there were loopholes for the rules to be circumvented. Automakers issuing pledges on Wednesday (Jun 11) included BYD, Chery and state-owned automakers BAIC and SAIC as well as smaller players like Xpeng and Xiaomi. Chery in its statement, for example, said it would strive to speed up the turnover of capital in the supply chain. But like other automakers, it did not mention how much of an improvement this would represent. The pledges come after China's industry ministry summoned automakers to a meeting last week where they were told to put an end to the price war and excessive competition – factors which have put tremendous pressure on the industry's supply chain. Even so, the China Iron and Steel Association felt compelled to publish a statement on Tuesday that said steel companies were struggling with little profit margin and mounting liquidity pressure as some automakers have been asking for price cuts of more than 10 per cent since last year and delaying payments by months. BT in your inbox Start and end each day with the latest news stories and analyses delivered straight to your inbox. Sign Up Sign Up The association also asked Chinese automakers to learn from the steady and healthy partnerships that Japanese automakers have with their suppliers, which leave a certain amount of profit for suppliers and ensure product quality and innovation. Tension has been high in China's auto industry as the price war which began in early 2023 has shown little sign of abating. In May, Great Wall Motor chairman Wei Jianjun worried openly about the deepening price war. He even said that the industry had its own version of property developer Evergrande which was liquidated last year after a major debt crisis, although he did not mention a specific auto company. This month, Chinese auto dealers also complained, calling on automakers to stop offloading too many cars on dealerships, saying the intense price war was damaging their cash flow, driving down their profitability and forcing some to shut. Yang Hongze, chairman of Autolink, a supplier of intelligent vehicle technologies, said he welcomed the automakers' pledges. 'It is a pleasant but difficult change for the industry to move towards a healthy development and grow together,' he said. But he added he would like more clarity from automakers about whether payments would be made in cash or commercial paper, and what would be considered the start date for the 60-day period to pay. In their pledges, BAIC and SAIC vowed not to pay suppliers with commercial paper. It was not immediately clear from their statements how often they had used commercial paper as a form of payment. The companies did not immediately respond to Reuters requests for comment. Commercial paper has been commonly used in the property sector, popular among developers because it is not categorised as interest-bearing debt. It promises suppliers a payment on a future fixed date, usually within one year, though the suppliers sometimes sell the paper before maturity at a discount in the secondary market. REUTERS
