Hard metamorphic rocks expected with gneiss, schist, quartzites and granite predominating. Internal lining to 5 m-diameter proposed. Design/build request for proposal due end-June, 2001. Visit www.jjg.com 25/01. Award imminent for $40 million, 1.28 km-long x 3.65 m-diameter steam distribution conduit to be driven for ConEdison beneath 1st Avenue by hardrock TBM between two 33.5 m-deep x 7 m-wide x 12 m-long shafts. Design/build contractor will select lining. Visit www.jenny-engineering.com 29/01. The Atlanta City Council has approved a $131.5 million contract for Obayashi Corporation to construct the Nancy Creek sewer tunnel. The purpose of the tunnel is to store rain and sewer overflows until the water can be treated. Much of DeKalb County's sewage flows into the Nancy Creek basin and the city system. The tunnel will originate in north DeKalb where about 4,000 feet (1,220 m) is to be built, and will continue another 7.9 miles (12.7 km) to an Atlanta sewer plant on a bank of the Chattahoochee river. Visit www.obayashi.co.jp/english/index.html 31/02.DeKalb County commissioners voted a resolution backing the city of Atlanta's plans to build part of the 12.9 km-long Nancy Creek sewage tunnel underneath the homes of several dozen DeKalb residents in a neighbourhood between Dunwoody and the city of Chamblee. The $131.5 million tunnel would begin just east of the Chattahoochee river near I-75 and run underneath parts of Atlanta. It would end in DeKalb. Construction awarded to Obayashi.

Water Conveyance

    8.3 km-long, $58 million Walnut Creek-San Ramon Valley transmission improvements project under design for September, 2001 by Camp Dresser McKee, Carollo Engineers and Jacobs Associates will include 1.46 km-long rock tunnel and four microtunnel drives of 64 m to 127 m. 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.

$100 million project involving 4.12 km-long x 4.12 m i.d. North Dorchester Bay and 830 m-long x 4.12 m i.d. Reserved Channel CSO consolidation conduits to be constructed mainly in glacial outwash sands and Boston Blue Clay at depths of 8 m to 17.5 m for MWRA. Tunnels to be constructed from large diameter shafts and connections with existing CSO outfalls to be made by drop shafts. Visit www.pbworld.com August 2000.The Massachusetts Water Resources Authority approved a USD300 million project which includes a 3.4 km 5.2 m-diameter tunnel near the shoreline in Dorchester and south Boston to collect the mix of storm water and sewage and hold it for processing. It also includes an odour control station at Carson Beach and a pumping station to be built at Conley Terminal in south Boston. If approved by state environmental officials, the project plans a "Little Dig" under Day Boulevard and Columbia Road, with a TBM burrowing the tunnel through soft ground. The tunnel is expected to start processing water when the station is completed in 2011. The plan is designed to close a gap in the USD4.5 billion Boston Harbour cleanup. Rain can overwhelm the city's combined system of storm drains and sewers, pushing untreated waste straight into the harbour. Visit www.mwra.state.ma.us 17/04.The Massachusetts Water Resources Authority (MWRA) on 19th July, 2006 awarded a USD145.7 million contract for the construction of a 5.2 m-diameter, 3,380 m-long tunnel in South Boston that will virtually eliminate combined sewer overflows (CSOs) and stormwater discharges to the beaches in South Boston. The contractor, a joint venture of Shank / Balfour Beatty / Barletta, will construct the North Dorchester Bay CSO storage tunnel in soft ground using a pressurized face TBM. The work will include a mining shaft at the downstream end of the tunnel, an equipment removal shaft at the upstream end of the tunnel, six intermediate drop shafts at the existing CSO outfalls, CSO and stormwater diversion and odour control structures, and associated shallow piping and utility conduits. The tunnel is expected to be completed in 2009.
