Three separate 4.24 m-diameter drives totalling 4.1 km using Lovat with chromium carbide plating on cutterhead face and rim to resist abrasion. 3.6 m i.d. honeycomb segments. Tunnels are Saccione (2.9 km), Tondo (1.7 km), San Firenze (1.4 km). Fourth tunnel at La Giostra will be 1 km long. Contractor: Ferrocemento Recchi Spa commencing tunnelling May, 1999 on two year programme. April 1999.Condotte d'Acqua purchased a 4.24 m-diameter single shield rock TBM from Lovat to construct the 2.5 km Castellaccio water diversion tunnel for irrigation, in Chiana valley in central Italy. The client is Ente Irriguo Umbro-Toscano. Boring through rock, the Lovat TBM model RMP167SE series 21700 is to erect a honeycomb type tunnel lining, consisting of prefabricated reinforced concrete segments, having an outside diameter of 4.1 m and an internal diameter of 3.6 m. One special design feature of the TBM is its ability to be assembled and disassembled internally within the tunnel. More specifically, the assembly and launch will be inside a tunnel chamber at the end of an existing tunnel. The disassembly will take place in a blind tunnel with no chamber, followed by the complete removal of the TBM through the tunnel. Arrival of the TBM on site expected for the end of April 2005. Visit www.lovat.com and www.condottespa.it 40/04.Condotte is close to completing the Castellaccio tunnel, which forms part of the primary water conveyance from Montedoglio dam to Valdichiana. The owner is Arezzo-based Ente Irriguo Umbro-Toscana. More than 50% of the 2.6 km-long circular tunnel is finished. Condotte took over the project from another contractor who failed to finish the job after boring 1.3 km of tunnel. 'Paoletta', a Lovat TBM model RMP167SE, is used. The excavated diameter is 4.25 m and the internal diameter is 3.6 m. Support and lining with prefabricated honeycomb segments. The assembly chamber of the TBM, at the junction with the section already built by the previous contractor, has been drilled and blasted and supported with steel ribs and shotcrete. The TBM will be pulled apart underground, without excavating an exit cavern.The tunnel alignment crosses Londa formations, made up of an irregular alternation of marls and silts, sometimes intercalated with banks of limestone and sandstone. The joints between the different components of the geological formation are often moderately altered and frequently filled with clayish material. Generally slight cover although its thickness may range at some spots 5 to 10 metres.Schoema locos and Palmieri muck cars for mucking-out. Cost of the project: EUR8 million. Click it/11.

Artelia Ville & Transport of Lentilly secured the EUR750,000 contract, excluding VAT, for environmental coordination of geological works from Saint-Martin-la-Porte during construction of the new Lyon-Turin rail link.

The owner, TELT (Tunnel Euralpin Lyon Turin), has awarded the contract (package 5A) for the preparatory work on the Avrieux shafts for the Lyon–Turin rail line to the Consortium  VINCI Construction Grands Projets (leader), Dodin Campenon Bernard and VINCI Construction France (65%), Webuild (33%) and Bergteamet (2%).

The works package involves preparatory work perpendicular to the future safety site at Modane, near the midpoint of the 57.5-kilometre base tunnel that will connect the international stations in Saint Jean de Maurienne (France) and Susa (Italy).

The EUR220 million contract for works package 5A involves construction of the four 500-m-deep Avrieux shafts using raise-boring machines (mechanical excavators operating from the base of the future shafts). This technique optimises work safety, costs and time. The work also involves digging galleries and seven caverns, using conventional methods (explosives), at the foot of the existing Villarodin Bourget–Modane decline, which is up to 22 m high and 23 m wide. The project will employ up to 250 people over the coming 36 months. Visit https://www.vinci.com/vinci.nsf/en/index.htm   and https://www.telt-sas.com/. 28/20.

Outer Loop Road

The Tokyo metropolitan government has presented a revised plan to extend the Tokyo Outer Loop Road, which puts most of the road underground rather than above ground. The 16 km extension begins in Nerima Ward and ends in Setagaya Ward. Nine kilometres between Nerima Ward and Mitaka, western Tokyo, would be constructed underground. The entire construction bill could amount to nearly ¥2 trillion.The 85 km Tokyo Outer Loop Road passes through Tokyo and three prefectures. The portion passing through Saitama Prefecture has already opened to traffic, while the portion passing through Chiba Prefecture is under construction. 45/02. The central government has signed an agreement with the Tokyo metropolitan government to build a 16 km underground motorway under Tokyo, beginning in Nerima and ending in Setagaya, one of the richest residential areas in central Tokyo. The new expressway, named Gaikando, will link the northwest areas of the capital to the southwest boroughs and will run at a depth of 40 m. TBM method to be used. Its cost is estimated at $9.6 billion. 03/03.The transport ministry and the Tokyo metropolitan government have agreed to build part of the Tokyo sector of the Gaikando expressway as a tunnel that will be more than 40 m underground. The planned tunnel will be 16 m in diameter. The Gaikando is a 86 km expressway running in a roughly 15 km radius of central Tokyo that will form the third circular expressway in the Tokyo metropolitan area.The underground plan covers one of the two Tokyo sectors, a 16 km stretch between Nerima Ward and Setagaya Ward. 12/03.

Japan, Tokyo - jp/16


The Oedo loop line in Tokyo will be completed in December, 2000. The first 12.1 km section of the 40.7 km line, which will provide almost 20 connections with suburban and metro lines, and major facilities and attractions, was opened in December, 1997 between Hikarigoaka and City Hall. Cost of the line, which was planned 28 years ago and approved for construction 14 years ago, has increased from $6.5 billion to $10 billion despite linear induction motor traction being selected to allow smaller, cheaper tunnels. March 2000.
