Official description

Christiani & Nielsen has had a long history since Rudolf Christiani, a young Danish civil engineer, and Aage Nielsen, a Captain in the Royal Danish Navy, established the company in Copenhagen in 1904 to build bridges, marine works and other reinforced concrete structures.

In less than 5 years, Christiani & Nielsen established a branch in Hamburg, Germany and, after World War I, further extended its operations to the United Kingdom, South America, Australia and Africa.

Christiani & Nielsen (Siam) Ltd was established in Thailand on 28th February 1930. Since then, the company has been responsible for a number of landmark projects including the Democracy Monument, Klong Toey Port, Krungthep, Krungthon and Nonthaburi bridges spanning the Chao Phraya River in Bangkok, the Rajdamnern Boxing Stadium, the Sukhothai Hotel in Bangkok, the luxury Baan Taling Ngam Resort Hotel on Koh Samui and the Asian Games Sports Stadium.

The Thai company was listed on the Stock Exchange of Thailand in early 1991 and in November 1992 changed its name to Christiani & Nielsen (Thai) Public Company Limited. In order to further strengthen operations worldwide, Christiani & Nielsen (Thai) PCL in December 1992 completed a reverse takeover of its publicly listed Danish parent company – the first such transaction in Thai history. Expansion into Malaysia, Vietnam and China, together with investment in engineering and property-related businesses followed soon thereafter.
