Lima metro breakthrough PERU – The TBM boring Line 2 of the Lima metro has broken through at Buenos Aires Station in the port of Callao. The Herrenknecht TBM, named ‘Micaela’,
is one of two machines that the construction consortium of Webuild, Dragados, FCC and Cosapi is using on the project. The 148m-long machine has a 10.27m-diameter and is designed for the groundwater soils in the area. It has excavated around 1,000m3
per day and
achieved an average daily advance of 15m-20m. TBM ‘Micaela’ has bored 2km of tunnel
from Insurgentes Station to Buenos Aires Station, and is underway towards Puerto del Callao, where it is expected to arrive before mid-year. On completing this route, it is to be
transferred to Gambetta Station to excavate and build the 8km-long of the branch line. The construction consortium’s second
TBM on the project is named ‘Delia’ and is designed to excavate in dry ground conditions. More than a year ago, the TBM completed the first section of the project, breaking through at Circunvalación Station. The TBM has bored 3km of tunnel from
San Juan de Dios Station to 28 de Julio Station, in the eastern part of Lima, and will continue excavating to Parque Murillo station in the city centre. It is to end its work at Insurgentes, in Callao. The US$3bn Line 2 metro project involves
the excavation of a 27km-long tunnel to connect the ATE and Callao districts, and the construction of an 8km-long branch to Jorge Chávez International Airport, forming the first phase of Line 4. The new line also includes construction of 37 stations, 36 ventilation and emergency shafts, and two train depots. So far the construction consortium has
completed 14km of tunnel – only some by TBM. The first 9km from Municipalidad de Ate Station to San Juan de Dios Station were built using NATM.
Hudson Tunnel looks to early works US – The Gateway Development Commission (GDC) has launched two procurements that pave the way for the Hudson Tunnel Project. The contracts are for the construction of
the Tonnelle Avenue Bridge and Utility Relocation and are early work components of the tunnel project. The bridge will carry Tonnelle Avenue in North Bergen, New Jersey over the
alignment of the new Hudson River Tunnel. The Tonnelle Avenue right of way will connect directly to the opening for the underground portion of the Hudson Tunnel at the western slope of the New Jersey Palisades. It is the first early work in New Jersey for
the new Hudson Tunnel and the first construction contract managed by GDC. Construction is expected to begin this
year. The 2.4-mile two-tube tunnel under the
Hudson River will provide a new connection between New York and New Jersey. The project also involves refurbishing Amtrak’s existing 112-year-old North River rail tunnel, which was badly damaged by Hurricane Sandy in 2012. Amtrak’s Northeast Corridor is the most heavily-used passenger rail line in the US. The contracts, being procured on behalf
of GDC with the support of the Port Authority of New York and New Jersey, include an Invitation for Bid for a contractor to build the project and a Request for Proposal for Construction Management Services for a firm to assist GDC in oversight and management of the project.
Auckland Light Rail marks start of physical works NEW ZEALAND – Physical works for New Zealand’s largest transport infrastructure project – Auckland Light Rail (ALR) – are under way with the start of below ground investigations to test soil and water conditions. A 40m-deep bore hole in Sandringham is
the first of several to be drilled so core samples can be analysed to help decide the most technically viable route for the rail system. During the next six months, ALR will sink
30 holes to depths of 10m-80m along sections of light rail’s indicative 24km-long route, half of which will is to be tunnelled. ALR will also draw on underground
information already gathered by two other big infrastructure projects – the City Rail Link and the Central Interceptor, Auckland Council’s underground wastewater pipeline. Information from the samples will help
ALR create a 3D picture of below ground conditions along the project’s proposed corridor. ALR’s CEO, Tommy Parker, said: “The first
pieces of a very complex infrastructure jigsaw are being put in place, the physical start to a challenging and exciting project that is going to bring so many positive changes to Aucklanders and our city.”
Funding of NZ$16m (US$9.8m) was
approved last year to allow Arup and Aurecon – the two companies in the project’s planning and design alliance – to jump-start their work. The ground investigation costs are included in NZ$48.45m (US$29.70m) approved for the alliance to undertake work necessary to progress the project for construction.
East Devon’s DH sees pipe-jacking UK – East Devon District Council has issued a contract notice for the pipeline design and construction of the Cranbrook- Monkerton District Heating Interconnector, which includes micro-tunnelling. Lot 1, valued at £25m (US$31m), includes
tunnelling – currently proposed to be undertaken by pipe jacking – under a dual carriageway and in proximity to an operational airport. It also includes the construction and
fit-out of a heat transfer station on an energy-from-waste site, construction of a 7.5km heat transmission main, and supply and installation of two heat transfer interfaces. Lot 2 is for operation and maintenance.
Atkins win on Dublin MetroLink IRELAND – Atkins has been appointed to deliver the detailed design for the advance works programme for Dublin’s MetroLink Project. The network, being delivered for
Transport Infrastructure Ireland, will be a high capacity, high-frequency metro railway and integrated public transport network connecting the Greater Dublin Area, including Dublin Airport and city centre. Atkins, supported by its subconsultant
RPS, a Tetra Tech company, is to develop the detailed design for a programme of activity to precede the main infrastructure works, including utility diversions, archaeological and heritage works, facilitation of land access and environmental monitoring. MetroLink is one of the key projects
identified in Ireland’s National Development Plan. The public transport infrastructure will be the first of its kind in Ireland, with much of the 18.8km route running underground. The project will link Dublin Airport, Irish Rail, DART, Dublin Bus and Luas services, linking major transport hubs and key destinations in the city centre. It is to carry up to 53 million passengers annually.
