Under the terms of the contract, WARE will manage the design, build, finance and maintenance of the 2.5 km extension from King George V station under the Thames to Woolwich Arsenal station. This includes overseeing the twin bored tunnel excavation under the Thames and the construction of a new station integrated with the existing Woolwich Arsenal Network Rail station. Each of the twin tunnels will have a diameter of 5.2 m and a length of around 1.8 km. The remainder of the extension runs in cut and cover. The JV is expected to reach financial close on the PPP scheme in time for construction to begin in spring 2005. Completion is due in winter 2008/09.

Lovat is to design and custom manufacture a 6 m-diameter soft ground machine. Crossing the Thames, the TBM model ME238SE series 21800 is to bore a 1.83 km twin tunnel. The machine will be erecting and installing prefabricated concrete segments, forming an 8-piece, tapered trapezoidal ring, having an outside diameter of 5.8 m and an internal diameter of 5.3 m. The machine features a screw conveyor with a peripheral drive mechanism for a rear discharge to a muck pump. This approach will be taken for material removal for the first 300-500 metres, then switched to a continuous belt conveyor for the remainder of the drive. The geology expected along the tunnel alignment will generally consist of terrace gravels, chalk and Thanet sands. This EPB machine is expected to encounter pressures of 4 bar. Delivery to the site is expected by November 2005. Visit www.lovat.com, www.amec.com and http://developments.dlr.co.uk/extensions/woolwich/index.shtml 25/05.
