This large team is always open to collaborative ventures and carries out complex assignments in a wide variety of fields. Through his interest in both architecture and the structural design of buildings, René Greisch instilled in his team the spirit of research and innovation on which its reputation among architects has been built, leading to numerous collaborative ventures with some of the top names. Bureau Greisch also has its own archi- tectural unit (canevas) in order to create an atmosphere where engineers are constantly questioning and searching for new solutions, both formal and technical. This spirit of teamwork and cooperation, a quest for synergy and collaboration, innovation allied to ima- gination, and a questioning and dynamic approach have become the methods and principles by which Bureau Greisch works. René Greisch’s approach is embodied in a desire for perfection, in which a work is constantly refined and polished up to the very last moment.

  • France : Elb Lends EUR 50 Million Towards Construction of Millau Viaduct
    %(, Luxembourg, 13 November 2002 )UDQFH(,%OHQGV(85PLOOLRQWRZDUGVFRQVWUXFWLRQ RI0LOODX9LDGXFW The European Investment Bank (EIB) announces a loan of EUR 50 million to Eiffage for part- financing construction of the Millau Viaduct, an exceptional 2.5km-long cable-stayed bridge spanning the Tarn valley on the A75 Clermont Ferrand – Béziers motorway. The benefits accruing from this EIB operation will be threefold : completing an item of infrastructure of European interest; fostering regional development; and enhancing the quality of life in the town of Millau. The viaduct, the only type of structure capable of providing a crossing of the Tarn valley compatible with motorway standards, represents a key component of the A75 motorway on the Paris-Barcelona route. This highway, forming part of the Trans-European transport network, will thus serve as a fully-fledged alternative to the Rhone corridor on which the majority of traffic between North-Western Europe on the one hand and Southern France and the Iberian Peninsula on the other currently converges. The viaduct is the sole part of the A75 being built under a private concession, with the remainder implemented entirely under the responsibility of the State in view of its role in improving access to the eastern part of the Massif Central. Once the viaduct is completed, the motorway will help to give fresh impetus to this Objective 2 region where agriculture and tourism are the mainstay of the economy. In addition, by eliminating the notorious crossing of Millau, one of the largest bottlenecks in France, the project will also impact favourably on the environment, while significantly enhancing the quality of life of the town’s inhabitants.

  • A New Approach to Tackling the UK's Infrastructure Challenges
    Joining the dots: a new approach to tackling the UK’s infrastructure challenges Aerial view of London at night © iStock 2 Contents Foreword 5 Executive Summary 6 Chapter 1: The case for change 10 Chapter 2: How we make decisions today 18 Chapter 3: What else should we look at? 22 Chapter 4: The right framework for decision making 36 Chapter 5: Good design in infrastructure 52 Endnotes 63 3 4 Foreword Politicians love to talk about infrastructure. Hard hats and hi-viz vests are a staple of election campaigns from Argentina to Zambia. This prominence is a testament to the political and economic symbolism of investing in infrastructure –new projects can be a source of national and regional pride, while clogged roads and packed trains can spell disaster. The UK urgently needs to invest in new infrastructure. Our transport network is dirty and over-crowded, housing too expensive and often in dangerously poor condition, and the regional imbalance of our economy grows by the day. TRANSPORT HOUSING ECONOMY A concerted and well-designed investment programme could play a huge part in addressing all of these challenges but the systems we have in place are not fit-for- purpose: without substantial reform we risk repeating the mistakes of the past. With this in mind, the Royal Institute of British Architects has spent the last 12 months looking at how we plan, design and build infrastructure projects in the UK to assess how well we are doing it and what we can do to ensure that the situation is improved. Our research revealed a startling picture: while politicians from all parties recognise the need for more investment, just adding more money to the current system would be an indefensible waste of resources.
