The BOT Concept

The Tate's Cairn Tunnel is a BOT (Build, Operate and Transfer) infrastructure project funded 100% by the private sector. The BOT franchise was awarded to the Tate's Cairn Tunnel Company Limited for a period of 30 years by the Hong Kong Government in 1988.

As suggested by the term BOT (Build, Operate and Transfer), the Tate's Cairn Tunnel Company Limited is responsible for the construction and operation of the Tunnel until the end of the franchise period. During the franchise period, the Company is allowed to earn a reasonable but not excessive return through the collection of tolls. On expiration, the tunnel will be transferred to the Government. The statutory requirements to the Company is defined by the Tate's Cairn Tunnel Ordinance.

BOT projects are embodiments of public/private co-operation for a better Hong Kong. To resolve the conflict between the demand for a better road network and the Government's desire to maintain fiscal prudence, private sector participation in transport infrastructure development provides a solution. Flow of private capital through BOT projects allows for rapid improvement of transport infrastructure in Hong Kong without massive public expenditures. Successful public/private cooperation in infrastructural projects enables the development of a better Hong Kong.

In Hong Kong, examples of major road projects built using the BOT model are Tate's Cairn Tunnel, Eastern Harbour Tunnel, Western Harbour Crossing, Route 3 ( CPS ) and Cross Harbour Tunnel.
