For over 70 years, we have been playing a vital role in shaping the iconic skyline of Hong Kong, mainland China and Southeast Asia through comprehensive construction, engineering, and property services.
Our story began in 1946, when our founder Mr Paul Y. Tso started Paul Y. Construction Co. in Shanghai.
Having completed a number of significant projects including the Lunghwa Airport and the Stock Exchange Building, we moved our operations to Hong Kong in 1949.
Our operation in Hong Kong started to take off with our participation in many major government projects.
Including the landmark Central Government Offices.
Riding on the tide of the city's glamorous development, the Group undertook construction of iconic landmarks.
Including Hilton Hong Kong and Shek Pik Reservoir.
We participated in building transport infrastructure projects.
Including the Hong Kong Cross Harbour Tunnel, the Mass Transit Railway and the Kai Tak Airport Runway extension.
We participated in the Dongjiang Water Supply Scheme and Yuen Long Sewage Treatment Works.

We delivered the Hong Kong Club in 1984.

We became involved in key transportation infrastructures, including Central-Mid-Levels Escalator and Walkway System, one of the longest outdoor escalator systems in the world.
