Koh Brothers Group Limited: A Legacy of Construction, Innovation, and Nation Building.

From humble beginnings in 1966, Koh Brothers Group Limited (“Koh Brothers”) has grown from strength to strength. In addition to providing engineering, procurement, and construction (EPC) services for infrastructure projects, the Group has diversified into real estate, building materials, and providing EPC services for water and wastewater treatment. Its expertise spans mechanical, electrical, and instrumentation control and automation (MEICA), hydro-engineering, biorefinery, and renewable energy projects. By expanding into synergistic business segments, the Group has diversified its revenue streams while optimising operational efficiencies across its core areas.

With a strong foundation, Koh Brothers today oversees more than 40 subsidiaries. These operate in countries including Singapore, Malaysia, Indonesia, and South Korea, and span three core sectors - construction and building materials, real estate, and leisure and hospitality.

Its strong reputation for delivering comprehensive end-to-end solutions has earned the trust of major clients and partners, including the Housing Development Board (HDB), Public Utilities Board (PUB), Urban Redevelopment Authority (URA), Land Transport Authority (LTA), Port of Singapore Authority (PSA), Jurong Town Corporation (JTC), Changi Airport Group (CAG), Ministry of Health (MOH), Ministry of Education (MOE), and Singapore Sports Council.

And for their steadfast deliverance of quality solutions for private, public, turnkey, or bespoke projects, Koh Brothers have been recognised through numerous awards and accolades. These include Construction Excellence and Green and Gracious Builder Awards from the Building and Construction Authority (BCA), the Singapore Prestige Brand Award, Promising SME 500 award, and several safety-related awards.

CORNERSTONES OF DEVELOPMENT

Notably, having been awarded the A1 grading by the BCA - the highest grade for contractors in Singapore - Koh Brothers is able to undertake public sector projects of unlimited value and their construction division has been instrumental in both shaping Singapore’s physical landscape and contributing to nation building.

Koh Brothers has built a majority of Singapore’s world-class drainage infrastructure, from small drains to rivers including Kallang River, Singapore River, Rochor Canal, Bukit Timah Diversion Canal, Punggol Waterway, Changi Water Reclamation Plant, Tuas Reclamation Plant, Marina East Desalination Plant and Marina Barrage.

Marina Barrage

Koh Brothers remains committed to embracing innovation and breaking new ground on the home front.

In the case of Punggol Waterway, this award-winning project was an essential element in HDB’s Remaking Our Heartlands initiative. It transformed a former agricultural area into a vibrant waterfront living hub, integrating recreational spaces and sustainable water technologies.

In addition to its construction process, Koh Brothers has also made a name for itself as a niche real estate developer, creating distinctive lifestyle-themed developments. Its projects range from luxury condominiums to innovative themed residences, showcasing a commitment to quality and unique living experiences.

Van Holland

These include Van Holland, which earned two accolades from the PropertyGuru Asia Awards (Singapore) - Best Luxury Boutique Condo Development and Best Boutique Condo Architectural Design Awards.

Their real estate portfolio also boasts state-of-the-art smart homes at The Montana, the astronomy-themed Starville, and the award-winning fitness-lifestyle themed Parc Olympia. Most recently, Koh Brothers developed Singapore’s first bike-themed executive condominium, Westwood Residences, featuring a purpose-built bicycle racing track and a one-of-a-kind velodrome. The development was also honoured with the Urban Land Institute’s award for ‘Active Transportation and Real Estate: The Next Frontier’.

Another notable mixed-used development, Nonhyeon IPark in the heart of the famous Gangnam district in Seoul, South Korea was completely sold at the launch of the project.

At the same time, Koh Brothers’ Leisure & Hospitality Division provides no-frills hospitality. Oxford Hotel, which comprises more than 130 rooms, and The Alocassia, a resort-style service apartment complex with 45 suites located on Bukit Timah Road, a prime district in Singapore.

LANDMARK PROJECTS AND ENGINEERING EXCELLENCE

Koh Brothers’ contribution to Singapore’s nation-building is most visibly evident in its involvement in numerous landmark projects. A well-known notch in their belt is the trailblazing and iconic Marina Barrage, which was officially opened in 2008.

At 10,000 hectares - or one-sixth of Singapore’s land size – it is the nation’s first urban freshwater reservoir to provide desalinated water to meet the country’s growing demand. Koh Brothers used their engineering expertise to design the barrage using a system comprising gates and pumps, which alleviates flooding in low-lying areas in the city.

For its efforts, the project was conferred the Superior Achievement Award - the highest honour for the best project entry - at the American Academy of Environmental Engineers Annual Awards in 2009. Marina Barrage was also recognised with the 2010 BCA Design & Engineering Safety Excellence Award - Merit Award (Civil Engineering), and the 2011 BCA Construction Excellence Award (Civil Engineering Projects).

Koh Brothers has also played a vital role in developing Singapore’s transportation infrastructure, contributing to the efficiency and connectivity of the city. Such projects include the construction of the Downtown Line 1 Bugis MRT Station and associated tunnels, Common Service Tunnel (Marina South) as well as the Lorong Halus Flyover and the award-winning Holland Road/ Farrer Road/ Queensway Interchange.

Marina East Desalination Plant

Meanwhile, Koh Brothers’ commitment to environmental sustainability is showcased in projects such as the Tuas Reclamation Plant, Marina East Desalination Plant, and, most notably, Changi Water Reclamation Plant - a state-of-the-art facility for used water treatment and recycling that forms part of the Deep Tunnel Sewerage System.

INNOVATING FOR THE FUTURE

As Singapore continues to evolve, Koh Brothers remains committed to embracing innovation and breaking new ground on the home front. It secured a S$1.12 billion project from CAG for the development of its three-runway operations at Changi Airport, and recently, it was also awarded a S$313.9 million contract by the LTA to design and construct a multi-storey bus depot.

Dry Fractionation Plant

Koh Brothers also has on its plate projects like the Marina East Desalination Plant - set to be the world’s first plant capable of treating both sea and freshwater - and Woodlands Health Campus, a modern and large-scale medical facility. These initiatives demonstrate Koh Brothers’ focus on developing solutions for the future needs of Singapore - from water security to healthcare – and their steadfast adherence to their company motto “Building Cities Building Dreams”.
