The Action is focused on an integrated approach to deal with the end-products of construction, clearly targeted at the development of R&D and engineering methods from structural points of view. It aims at providing the construction sector with a new framework and ideas based on the integration of approaches and results of ongoing research and development projects. The Action establish a broad network of European universities and other research centres in the field of structural engineering in order to transfer the state-of-the-art of technologies, design methods and practices through the existing and new links of members of the Action in several international organisations. The Action involves collaborative analysis of results concerning design and assessment methods and tools, advanced materials and technologies as well as construction processes, both for new constructions and the rehabilitation of the existing ones. 1.2 Background The urban and natural environments are inseparably linked. Energy, materials, water and land are all consumed in the construction and operation of buildings and infrastructure to such an extent that sustainable development can be said to decisively depend on the built environment. The urban environment itself influences our living conditions, social well-being and health. The European Commission has adopted a thematic strategy on the urban environment; one of the four priority themes is sustainable construction. All themes are cross-cutting in nature and have strong links with many environmental issues. Environmental, socio-economic and cultural issues in the construction sector are characterised by their complexity, the diversity of actors concerned and the need for innovative and multidisciplinary solutions. As the largest and most fragmented industry, the sector faces huge chal- 1
