The Hong Kong-based joint venture Leighton-Gammon JV is currently using more than 30 Atlas Copco compressors in the construction of the US$ 1.23 billion West Kowloon Rail Terminus (WKT). WKT covers an area of 25 acres (10 ha), and will be predominately built underground. With 15 platforms and a design to handle some 100,000 passengers per day, the completed WKT is expected to be the largest terminal of its type in the world. Construction requires 1.7 million m3 of open cut excavation to a depth of 33 m, and the use of 600,000 m3 concrete and 150,000 tonnes of steel. This equates to an excavation of approximately 5,000 m3 of earth per day, or 800 truckloads. The terminus will be surrounded by pile wall of about 500 m3 diameter bored piles sunk to a depth of 40 m, along with 5,000 H-section piles.
