Defining NMT as part of the NATM SCL debate
The Norwegian Method of Tunnelling (NMT) has its origin mostly from Scandinavia. Numerous case records, eventually more than 1,250, were finally mostly from Norway, with many early cases from Sweden. It is this (and numerous single-shell caverns from other countries too) that stimulated the original development of the Q-system of rock mass classification and the tunnel support class definition.

In search of resilient cities
The world's population is on a vast urban migration to super-sized megalopolises. By 2050, an estimated 70% of the world's people will live in urban areas, up from the current 50% recorded in 2010. Developing the infrastructure to accommodate such huge populations and provide urbanization that is effective, adequate and sustainable is the task of city planners and engineers. At the 2011 ITA World Tunnel Congress in Helsinki the Association's Committee on Underground Space (ITACUS) staged the opening event of a global initiative to promote the use of underground space as a crucial element in the quest for building sustainable cities that are resilient to both the natural and man-induced disasters that are likely to confront them. TunnelTalk Editor Shani Wallis reflects on the ITACUS Open Session in Helsinki and looks ahead to Bangkok 2012 where the debate will continue.

ITA post congress analysis
The buzz in the corridors was positive; the talk of big projects moving ahead, immanent; progress of major projects worldwide, reported; and space for exhibitors was sold out long ago. Being at the ITA conference last week in Budapest was another exercise in asking; 'so where is this global recession?' Despite prefaces from several speakers about the dire affects of over-reactive tightening of credit by self-inflicted over-extension by banks - the need to build underground infrastructure is at record highs and now is the right time to get these projects into construction, while supply-line indices are down. Most countries in the world are programming many billions of capital investment to provide the groundwork for the cities and societies in which we will live in the near future. TunnelTalk was among the many who travelled to Budapest for the Association's 35th General Assembly, congress and exhibition, to report the major developments and topics of discussion.
