Loh & Loh Construction is a Singapore civil engineering and construction group headquartered on Hamilton Road in Kallang, with a history that stretches back to the 1960s. The company began as a closely-knit family business working as a general contractor on small home renovation and housing projects, and grew — on the strength of quality work and dedicated customer service — into a major civil engineering and construction group with over 50 years of successful projects in Singapore and the region.
Today the firm is known for expertise across four core areas: civil works, building and architectural works, design and build projects, and process plant construction and maintenance. Its civil and marine engineering capabilities span land reclamation, earthworks, dredging, reservoir and dam construction, bridges and roads, drainage, seawater intakes and underground piping, while its building team takes on everything from admin and control buildings to warehouses and blast-resistant structures.
The company's project list includes some of Singapore's landmark infrastructure: the nation's first LNG terminal, its first seawater desalination plant, the spillway system and reservoir development of the Lower Seletar Dam for PUB, the Mainland Ferry Terminal and Treatment Plant on Jurong Island, Kranji Golf Course, and facilities for ExxonMobil and Chevron Oronite.
Safety sits at the heart of the company's identity, backed by a public pledge of zero harm to people and the environment. That commitment has earned BizSAFE Star certification, ISO 45001 recognition for its health and safety management systems, the BCA Green & Gracious Builders Award, and honours at the WSH & bizSAFE Awards.
On Hamilton Road in the Kallang district of Singapore sits the headquarters of a company whose work most residents will never see up close — but whose fingerprints are on some of the nation's most important infrastructure. Loh & Loh Construction is a civil engineering and construction group with a history stretching back more than fifty years, and its journey from a small family contractor to a builder of national landmarks is a distinctly Singapore story.
The company first opened its doors in the 1960s as a closely-knit, efficiently run family business. In those early days, Loh & Loh worked as a general contractor on small home renovation and housing projects. From the start, the focus was on delivering quality construction work and dedicated customer service — qualities that earned the firm a growing reputation, and with it, growing demand.
As the company expanded to meet its customers' increasing needs, that once-modest business gradually transformed into a major civil engineering and construction group. Today, its portfolio includes projects familiar to almost everyone in Singapore: the country's first LNG terminal, its first seawater desalination plant, and the spillway system and reservoir development of the Lower Seletar Dam for PUB, Singapore's national water agency.
Loh & Loh specialises in a wide scope of construction and engineering projects across all types and categories of construction works, organised around four core areas of expertise.
Civil Works form the foundation of the practice. The team's civil and marine engineering experience covers land reclamation, earthworks, dredging, reservoir and dam construction, bridges and roads, and drainage. Its portfolio includes the construction of seawater intakes, seawater channels and seawater intake cofferdams, along with excavation works and a wide range of underground piping — sewer lines, seawater pipes, water lines and more.
Building & Architectural Works is another strength. The company has the capabilities to take on all aspects of a project's development, including architectural, sanitary, plumbing and finishing works. It constructs admin and control buildings, warehouses, and buildings requiring external and internal hardening or blast resistance — the kind of specialised structures demanded by industrial clients.
Design & Build projects have built the firm a solid reputation as a one-stop partner, with design, procurement and construction all handled by a single professional team. The projects it has constructed are familiar names in Singapore: the Mainland Ferry Terminal and Treatment Plant on Jurong Island, the Kranji Golf Course, and various facilities for ExxonMobil, among many others.
The fourth pillar is Process Plant Construction and Maintenance Works. Building a process plant can be a mammoth, challenging project — one that needs to be in the right hands. Loh & Loh's team has the experience to first plan and construct process plants, then provide the regular maintenance needed to keep them fully operational.
Construction is an industry where a company's values are tested every day on site. Loh & Loh's safety and environmental pledge is explicit: the company is committed to achieving zero harm to people and the environment, and promises to undertake all reasonable and practicable steps to prevent and eliminate any foreseeable risks. Safety, the company says, is in its policies, procedures and DNA — and its safety record is presented as evidence in itself.
That commitment has been recognised. The company holds the BizSAFE Star certification — the highest BizSAFE level, awarded to companies with exemplary workplace safety and health management systems — along with ISO 45001 certification for its health and safety management systems. It has also received the Green & Gracious Builders Award from Singapore's Building and Construction Authority, which promotes environmental protection and gracious practices during construction, and has been honoured at the annual WSH & bizSAFE Awards organised by the Workplace Safety and Health Council.
Three qualities recur across the company's own telling of its story: proven heritage, with over 50 years of successful projects in Singapore and the region; a one-stop design and build capability; and world-class safety. For clients in the water, pharmaceutical, energy, and oil and gas industries — the sectors the company serves — those qualities matter when a project is too complex or too critical to get wrong.
