Euro African tunnel in sight
A proposed twin rail tunnel linking Europe and Africa may be carrying traffic as early as 2025, according to Spanish engineers (GE June 2005). The Spanish and Moroccan governments have now called in Swiss tunnelling expert Giovanni Lombardi to produce a preliminary scheme of how the work might be carried out for the 40km route.
Longest sub-sea pipeline opens
The world's longest sub-sea pipeline linking Norway's offshore gas fields to the UK gas network was opened last month. The Langeled pipeline will deliver 20% of the world's future gas needs and carry gas from Norway's Sleipner offshore hub to a UK terminal at Easington in East Yorkshire under phase one. Under phase two, the pipeline will connect the UK to Norway's Ormen Lange field by October 2007.
Worcs gets flood protection
The Environment Agency last month unveiled a £7M flood protection system for Bewdley Severnside in Worcestershire.
The scheme includes a 140m permanent defence and consists of an aluminium barrier linked to an underground wall and concrete ground beam.
San Francisco toughens tube
A metro line underneath San Francisco Bay will undergo a major seismic retrofit amid fears the tunnel could rupture in a major earthquake.
The ground is being strengthened around a 3.6km Transbay Tube section that runs underneath the base of the World Trade Centre.
The works are designed to prevent liquefaction of the soils in the event of an earthquake.

There were also errors in the article headlined 'Geotechnical go-ahead for huge cube cutout in Canary Islands mountainside' (GE September 2006). Arup is working for architecture practice Estudio Guadiana and Scott Wilson Piesold and Itasca is working for Arup as subconsultant. The 3DEC software was not a bespoke programme but was adapted for the project. The 3DEC programme modelled 3,000 to 4,000 joints in the rock, but the actual number of joints is much higher.
