    Major scheme to provide 650 million gal/day of water for Southern California. 29 km of 12 ft finished diameter tunnels under construction by Shank/Balfour Beatty in three lots: Arrowhead West (6.2 km), Arrowhead East (9.6 km), and Riverside Badlands (13.2 km). Arrowhead East has advanced 2.55 km using contractors own 5.6 m-diameter TBM and similar machines under erection at Arrowhead West and Riverside Badlands. Extensive grouting programme undertaken to reduce water inflow. Project completion scheduled for December, 2003. Sept 1999.   These tunnels cross both the San Andreas and San Manuel faults. Pre-excavation grouting using microcements was being carried out ahead of the TBMs, and backfill grouting around the carrier pipe in the completed tunnels was planned. However, despite the injection of 1,250 t of cut-off grout, which reduced the water inflow from 1,400 gal/min to 275 gal/min, Arrowhead East tunnel has been closed down after completing 2.5 km of drive. Arrowhead West is also closed for similar reasons, and the Metropolitan Water District of Southern California has replaced the management and is considering options for realignment of both tunnels or their abandonment and replacement by pipeline. Riverside Badlands tunnel is unaffected, but it is reported that the Parsons Brinckerhoff construction management team has been replaced by a team from Hatch Mott McDonald. January 2000.   Shank/Balfour Beatty reports good progress on Riverside Badlands tunnel, the only one of their original three contracts that is still in place, Arrowhead East and West having been terminated due to unforeseen groundwater conditions. An average of 52 m/day is being achieved and the 12.8 km-long x 4.8 m-diameter tunnel is nearly half-complete.

The contract has a value of USD428 million. The project is named East Side Access, Manhattan tunnels.Dragados will use two rock TBMs to bore four tunnels totalling 7.5 km and 6.7 m in diameter. No tunnels have been built for more than 20 years to expand the subway or suburban rail systems in New York. In the years 1980-1984, lot 5B of the LIRR in Manhattan has been excavated with a 6.20 m-diameter Robbins TBM. The main contractor was then Impregilo. That was the first time a TBM was used for metro or rail systems in New York. The New York subsoil is rock and 265,000 cubic metres will be extracted. Work starts immediately and will take up to four years and two months. Click us/18.

The MTA Capital Construction (MTACC), acting as an agent and in behalf of the Metropolitan Transportation Authority (MTA), is seeking individual firms or joint ventures who are interested in being the prime contractor for contract CQ031, to submit qualification documents as part of a two step Request for Proposal (RFP) process. For more information visit www.mta.info/nyct/procure/contracts/cq031.pdf 31/07.A single bid to help carve out space for a new Long Island Rail Road (LIRR) terminal under Grand Central Terminal came in USD200 million higher than anticipated. The Metropolitan Transportation Authority (MTA) had estimated the job to cost USD670 million. Instead, the bid came in closer to USD870 million. The sole bid was submitted by a joint venture between Judlau Contracting and Dragados. Last year, Judlau and Dragados were awarded a separate USD428 million contract to tunnel under Manhattan in preparation for the LIRR's expected 2013 arrival at Grand Central. The MTA explains that an uncommonly large number of construction projects in the US and worldwide may have led to less interest from bidders. The job may be split into several smaller contracts and the MTA is currently exploring whether a new call for bidders could delay the project beyond its expected 2013 completion. 46/07.Jacobs Engineering Group announced on 29th April that it received, in joint venture with its partner LiRo Engineers, a contract from the Metropolitan Transportation Authority Capital Construction Company to provide consultant construction management services for the East Side Access project in New York City. The value of the seven-year contract is estimated at USD75 million. The project involves boring nearly 11.2 km of railroad tunnels in Manhattan and Queens, laying 15,250 metres of track, building a new terminal under Grand Central Terminal, and building a new commuter station in the Sunnyside Yard in Queens in addition to extensive infrastructure work. Visit www.jacobs.com and www.liro.comThe new tunnel and track system will provide an alternative route for the Long Island Railroad (LIRR) trains that currently travel underground to Pennsylvania station on Manhattan's West Side into the new terminal under Grand Central Terminal on the East Side. The connection will increase the LIRR's capacity into Manhattan and shorten travel time dramatically for commuters travelling from Long Island and eastern Queens to the East Side of Manhattan.The project requires using tunnel boring machines to excavate more than 1.5 km of hard rock dual-bored tunnels under Park Avenue in Manhattan and to bore four soft ground tunnels to the Sunnyside Yard in Queens. In addition to building the concourse under Grand Central Terminal, the project includes construction of new entrances, ventilation buildings, and substantial surface work, such as retaining walls and track realignments, that will be completed during ongoing rail activity in Sunnyside Yard. 20/08.

  Monumental expansion programme to meet the future water needs of Las Vegas includes a lake tap shaft to depth 76 m beneath the lake surface to be bored from a barge; an intake tunnel in jointed and faulted metamorphic rock; 22 x 1.82 m-diameter pumping shafts bored from surface to the 100 m level; and a 3.65 m-diameter subaqueous concrete pipeline. Kiewit Construction has completed the 7.6 m-diameter access shaft to the 115 m level and the 792 m East tunnel has broken through using drill/blast supported by rockbolts and shotcrete at a rate of 6 m/day. Work progressing on the 502 m intake tunnel. Zeni Drilling has completed the first shaft. March 1999.   Atlas Copco 322 twin-boom and basket drilling 3.8 m holes for 2.5 m advance in intake tunnel. Mucking out by Wagner 3.5 Scooptrams. Support by fully-grouted Ingersoll Rand C-tube rockbolts of lengths to 3.8 m and 10 cm of fibre reinforced shotctrete. Forward grouting commenced after 250 m after water inflows of 600 gal/min were encountered. 25 m probe holes have been necessary. The well shafts are being pilot drilled blind to full depth using a reverse circulation rotary drillrig and then reamed to the 1.82 m final diameter to accommodate the 1.3 m diameter pumping columns. June 1999.  Zeni reported completion of all 22 well shafts, including casing and grouting. The bases of the well shafts have been exposed by a top heading through the forebay, and the bench is now underway to complete. Breakthrough of intake tunnel into shaft scheduled for late-November, 1999 and flooding of tunnel in January, 2000. November 1999.The Southern Nevada Water Authority has awarded a USD447 million contract to Impregilo and its US subsidiary S.A. Healy to design and build the so-called third straw to draw water from the Lake Mead reservoir. This is a concrete-lined tunnel 6 m in diameter and approx. 4.8 km long underneath the bed of Lake Mead. Construction should begin before the end of the year and eventually involve a massive tunnel boring machine that will be manufactured in Germany and shipped to the United States. The third straw is slated to go on line by early 2013. Visit www.impregilo.it and www.sahealy.comThe Lake Mead reservoir on the Colorado River behind Hoover Dam supplies about 90% of the water used in and around Las Vegas, but the lake level continues to drop in the face of an eight-year drought. The new intake will allow the authority to continue drawing water even if Lake Mead shrinks below the level of the two existing straws. One or both of the existing inlet pipes would be forced to shut down if the lake level falls below current intakes. Lake Mead is currently at a surface level of about 340 metres above sea level, or about 20 metres above the 320 m level of the original intake. A second intake draws water from 305 metres above sea level. It was completed in 2002, at a cost of about USD80 million. The third intake is expected to draw water from below a 275 m elevation. 13/08.The Southern Nevada Water Authority is also soliciting bids, deadline 21st April, 2008 for the Lake Mead intake No. 2 connection and modifications project (contract No. 070F 05 C1). The proposed underground works include connection to the existing intake tunnel and modifications to the existing intake structure, including but not limited to a 6.7 m-diameter 116 m-deep shaft, a ventilated building over the top of the shaft, a 4.3 m-wide by 4.9 m-high by 82 m-long modified horse shoe tunnel from shaft to existing IPS-2 tunnel, 4.3 m-wide by 4.9 m-high by 76 m-long modified horse shoe tunnel connection to the future tunnel from intake No. 3, and existing IPS-2 intake modifications. Visit www.snwa.com/nonpvcs/construction_ops/inv/070F05C1.pdf 13/08.Further technical details are available regarding the Lake Mead intake No. 3 shafts and tunnel project, recently awarded to Vegas Tunnel Constructors, a joint venture of Impregilo and S.A. Healy. The tunnel will primarily be excavated in late Tertiary sedimentary and volcanic bedrock. Of the 4,666 m-long intake tunnel, about 300 metres will be excavated in the Saddle Island Lower Plate (amphibolites, schist, and gneiss) and about 370 metres in the Saddle Island Upper Plate (schist, amphibolites, gneiss, pegmatite, dacite intrusives). The majority of the tunnel drive (about 3,540 metres) is located in the Muddy Creek formation (conglomerate, breccias, sandstone, siltstone and gypsiferous mudstone). As the TBM approaches the intake riser, it will pass through about 370 metres of red sandstone, and the final 90 metres will be in the Callville Mesa basalt.Except for an erection chamber and starter tunnel that will be excavated by drill and blast, the tunnel will be excavated by a Herrenknecht convertible hybrid tunnel boring machine. The TBM, in open mode, will evacuate the spoils by screw conveyor feeding a continuous tunnel conveyor. The continuous tunnel conveyor will feed two muck skips that are hoisted up the intake access shaft and then moved to a stockpile on site. In closed mode, the screw conveyor is retracted from the cutterhead and the TBM functions in fully slurry mixshield mode, utilizing a separation plant. The tunnel will be supported by a precast, bolted, gasketed tunnel lining with five plus a key segments. Inside diameter will be 6.1 m, and the segment ring will be 1.83 m long. Visit www.herrenknecht.comOther underground structures include the 180 m-deep intake access shaft with cast-in-place concrete liner with inside diameter of 9 m, excavated by drill and blast. A stub tunnel approximately 26 m long will be excavated by drill and blast at depth of about 110 metres to provide a connection to the future pump station. At the bottom of the shaft will be a large TBM erection chamber, starter tunnel, and tail tunnel that will provide the Southern Nevada Water Authority (SNWA) with an option for a future tie-in and water transmission. The intake riser will be constructed in Lake Mead at a depth of 90-107 m below the lake surface. Lake-bottom excavation will be by underwater drilling and blasting. The intake riser will be constructed by sunken tube technology and will provide a docking station for the TBM.The construction manager is Parsons Water and Infrastructure. SNWA’s design engineer is MW/Hill, a joint venture of Montgomery Watson and CH2M Hill. The contractor’s design engineer is Arup USA, with Brierley Associates.
