Visit www.jacobssf.com 10/01.Modern Continental will install a large diameter transmission pipeline and build a 1.6 km tunnel through central Walnut Creek for EBMUD (East Bay Municipal Utility District). The tunnel starts at the Kaiser overflow parking lot on Newell and goes north under the flood control channel to the armory, near Civic Park. There will be two shafts dug to provide access to the tunnel. The shaft at Newell will be 24.4 m-deep. The shaft at the armory will be 8 m-deep. Crews will build a TBM on a rail in the shaft on Newell and the boring machine will proceed to the shaft at the armory. The Newell shaft is the primary staging area. Modern Continental will use a Herrenknecht 2,000 mm microtunnelling machine, previously used on the Pentagon project in Arlington, Virginia. They will also use an EPB shield and an excavator shield to complete the balance of the tunnelling. Work on the tunnel will begin on 23rd January, 2003 and will be completed in 2004.
