Christiani & Nielsen (Thai) Public Company Limited:

Christiani & Nielsen (Thai) Public Company Limited is a leader in civil engineering and construction. Renowned worldwide, Christiani & Nielsen is recognized for its expertise, experience, and advanced technology in the field. The company has a long-standing history, originating from a small engineering firm in Denmark, founded by Dr. Rudolph Christiani and Captain Aage Nielsen on February 28, 1904.

In its early years, the company primarily focused on bridge construction, marine engineering, and reinforced concrete structures. Within less than a decade, Christiani & Nielsen established its first international office in Hamburg, Germany, in 1908. This expansion continued across Europe, Asia, America, Africa, and Australia, leading to numerous large-scale projects, including high-rise buildings, roads, bridges, dams, ports, tunnels, airports, gas separation plants, stadiums, and metro stations.

Christiani & Nielsen has continually developed innovative civil engineering technologies, particularly in the application of reinforced concrete structures. The company has contributed to significant engineering projects worldwide, such as developing the reinforced concrete relieving platform for quay walls and vertical piling systems for stability, known as the CN Wharf. It also pioneered the Cast-Push Method for bridge construction, which later became widely adopted worldwide.

In Thailand, Christiani & Nielsen was established in 1930 under the name Christiani & Nielsen (Siam) Ltd. The company has been involved in the design and construction of key projects contributing to the country’s economic and infrastructural development for both the public and private sectors. Many of these projects have become iconic landmarks, such as the Democracy Monument, Klong Toey Port, the Bangkok Bridge across the Chao Phraya River, and the Sarasin Bridge in Phuket.

Today, Christiani & Nielsen is listed on the Stock Exchange of Thailand under the name Christiani & Nielsen (Thai) Public Company Limited, since 1992. With over 90 years of construction experience, the company continues to expand its operations within Thailand. To support future growth, Christiani & Nielsen has established a new subsidiary, Christiani & Nielsen Energy Solutions Company Limited, in which it holds an 85% stake. Based in Thailand, this subsidiary focuses on providing sustainable energy solutions, including solar energy, wind energy, and other renewable energy sources.
