An Interview with PRS-Med’s VP of Business Development and Marketing Hadas Levin by Chris Kelsey The year 1977 has become a watershed year for polymeric construction materials. Dr. J.P. Giroud coined the terms ‘geotextile’ and ‘geomembrane’ in a key paper at the First International Conference on Geosynthetics; and the United States Army Corps of Engineers (USACE) published a report on its testing of cellular confinement systems (first undertaken in Vicksburg, Mississippi in 1975). The investigations in Mis

A novel approach to utilities installation will lengthen the life of Helsinki's streets, reports Mike Woof. A major utilities project in Finnish capital Helsinki will offer huge benefits for the city's streets and traffic flow rates in years to come. A new tunnel system is being excavated under Helsinki for the power company Helsingin Energia, although this will be co-owned by the city. Called the Common Utility Tunnel (Meilahti-Pasilak-Käpylä LU2), the excavations form an extensive network spreading out un

ECED's first Dealers' Conference in April during Intermat resulted in "a tremendous success and solid future outlook for the association". The president of the European Confederation of Equipment Distributors (ECED), Dr. José Gameiro, said the gravity of the current crisis is "the worst in the past 50 years, with a devastating effect on equipment distribution for public works and civil construction."

A tricky utility supply project has been carried out in difficult conditions in Germany, without disturbing a village access road. The drilling work for the project was operated by boring contractor Beermann and the site was located on a plateau some 5km from the nearest village.

An alliance of companies has come together to realise major infrastructure projects in Latvia including its biggest bridge. Patrick Smith reports. Riga, the Latvian capital, has the finest collection of Art Nouveau buildings in Europe and its centre is on the UNESCO World Heritage List. The city of some 750,000 people (the country's total population is 2.2 million) is bounded to the south by Lithuania and to the north by Estonia, and is the second largest in Baltic States. To the east is Russia and Belarus.

Results show the state of Europe's tunnel infrastructure at its 'most sublime and most depressing quality' as Patrick Smith reports. EuroTAP [European Tunnel Assessment Programme] 2010 has unveiled the results of inspections conducted earlier this year in 26 major tunnels in 13 European countries. The on site inspections, carried out between 12 April and 20 May, 2010, are said to indicate that an "alarming number of operational tunnels across Europe will not be ready to comply with EU tunnel safety rules wh

The low risk found for driving through the tunnel is primarily due to the low volume of traffic of around 11,000 vehicles/day and the ban on HGVs and the transport of hazardous goods. Unidirectional traffic, sufficiently wide lanes, emergency lanes and lighting are the main reasons for the very good result for preventive measures. The tunnel is monitored around-the-clock in a tunnel control centre manned by trained staff, and incidents are automatically reported to the control centre by video link. If neces

An innovative solution was put forward to support slip roads on a Dutch motorway. Patrick Smith reports. The 2010 opening of the A7 motorway extension on the southern ring road of the city of Sneek, The Netherlands, brings an end to local traffic misery. By using innovative Tensar Geocell Foundation Mattress technology over weak estuarine clay, MNO-Vervat Noord, the main contractor, constructed a key junction and its slip roads in weeks instead of months, with considerable cost savings.

Construction work on the longest bridge in Malaysia and South-East Asia is well underway. Malaysia and South-East Asia is well underway. When completed, the cable-stayed bridge will have a two-lane carriageway and a motorcycle lane in each direction, and will connect Batu Kawan on the mainland to Seberang Perai and Batu Maung on Penang Island. The main span will be 250m long with a length over water of 17km and a 30m height above the water. Costing an estimated US$1.5 billion the 24km long bridge is being b
