Kier Zen Pacific joint venture is now 17 months into construction of the £110M Mei Foo West Rail station, which is shoehorned into a site tightly bounded by major roads, a flyover and a massive high rise housing estate.
Designed by Hyder consulting, part of the station structure has to be squeezed under the viaduct which carries the busy Ching Cheung Road and which will provide some shelter to the station platform.
Complicating matters still further, the station footprint crosses above the underground tracks for MTR's Tsuen Wan mass transit railway line. As a result piles supporting the structure have to be sunk on either side of the track bed as well as between the tracks, so the tunnel and station structures can remain independent of each other.
Access to the site is extremely restricted, making construction sequencing vital to the smooth flow of equipment and materials around the site. As with Nam Cheong Road, value engineering by the contractor has played a vital role in keeping costs down. By using larger diameter piles and slightly modifying the station design the number of piles required was cut from around 800 to 600. Like neighbouring Nam Cheong Road, Mei Foo will have a link to the MTR.
Here though, passengers will have to make their way through a specially constructed tunnel link between the two separate stations rather than simply changing platforms.
