This edition of the Journal is dedicated to Cressida Spachis who sadly passed away earlier this year. Her paper, “Delivery of bus priority projects - a partnership approach”, was submitted to the Technical Journal to showcase the success of working in partnership on the Route 38 Project. Cressida was Project Manager for the Route 38 Corridor Management Pilot Study which has developed principles for intensified bus priority now being used across London. The project received many accolades and Cressida was due to be part of the client/consultant team receiving the Improvements to Bus Services award at the London Transport Awards earlier this month. A further tribute to Cressida is made by Andy Southern, Managing Director for Transport Planning and Management, on page 69 immediately prior to the text of her paper. Once again there has been a great response to the call for papers across all businesses and it is particularly encouraging to have been able to publish papers from a wide range of staff grades covering Graduate Engineers to Technical Directors. The Journal continues to highlight the extensive range of technical disciplines Atkins can offer its clients and our Defence and Offshore Energy capabilities are prominent in this edition. With the recent appointment of three new Network Chairs we can look forward to even more effective showcasing of the diverse and complex problems that Atkins’ staff solve so well in their everyday activities. It is also particularly pleasing to see the excellent working relationships we have developed with our clients and partners being manifested in co-authored papers such as those written with the University of Bath, University of Southampton and English Heritage. This demonstrates that Atkins creates solutions that both we and our clients are proud of. I hope you enjoy the selection of Technical papers included in this edition.

The bridge is a 180m long four span steel composite viaduct. Due to site constraints the most economical and practical method of construction was to launch the steelwork into position rather than to lift the steelwork in by crane. The bridge steelwork, weighing over 800 tonnes, was assembled on the northern approach to the bridge and launched southwards over the River Esk estuary This paper demonstrates that the design and construction of a launched bridge can be significantly more complicated than the design of a comparable bridge which is constructed using conventional methods, and that there are many more load cases and construction details to consider. This paper covers the approach for carrying out the analysis, design, detailing and construction of the structure and focuses specifically on the key issues relating to launching steelwork. It serves as a useful guide and quick point of reference for the design of launched steel bridges. Introduction This paper covers the approach for carrying out the analysis, design and detailing of the River Esk Bridge on the M6 Carlisle to Guards Mill Motorway Extension. The Esk bridge is a four span 180m long steel composite viaduct over the River Esk and carries the southbound carriageway of the new section of M6 Motorway. The span arrangement is 31.4m/51.9m/51.9m/44.9m. The south abutment is fully integral, forming the point of fixity, and the superstructure is free to move longitudinally over Figure 1 - River Esk Launch the piers and north abutment. The bridge steelwork was assembled on the northern approach to the bridge and launched southwards over the River Esk estuary. The total weight of the steelwork was over 800 tonnes. STRUCTURE The reason for the launch was that access to the river for steelwork assembly and lifting was not possible due to the tidal nature of the river and the high risk of flooding. Also, lifting the beams in from the adjacent A74 ‘Metal Bridge’ was not possible due to traffic management issues. The A74 Metal Bridge was refurbished to carry the M6 northbound carriageway. Figure 2 - River Esk Launch S 5 51 The launching of River Esk Bridge Analysis, design and buildability Line beam analysis of launch phases Launch Phases The bridge steelwork was launched southwards in two phases: Phase 1 - The southern half of the steelwork was assembled on temporary land bases together with a launch nose and tail, and then launched southwards. The launch platform comprised the landbases, spaced at 28m/28m/28m, constructed in the partially completed approach embankment with the landbase levels set so that the steelwork could be set out and assembled to the Figure 3 - Views of the completed bridge adjacent to the existing A74 metal bridge vertical alignment required for the launch. The piers in the river were constructed in temporary cofferdams which were then converted into temporary islands to allow safe access and working at the piers without the risk of flooding. The cofferdams and islands were constructed higher than the maximum predicted flood level. Phase 2 - The tail was removed from the Phase 1 steelwork. The northern most steelwork spans were assembled and attached to the steelwork already launched. The tail was reattached to the rear of the Phase 2 steelwork. The whole bridge steelwork was then launched. On completion of the launch the temporary launch nose and tail steelwork were removed. The launch equipment comprised strand jacking tendons which were attached to the north abutment using Figure 4 - Views of the completed bridge adjacent to the existing A74 metal bridge a steel hauling frame which was embedded into the concrete stem of The M6 Carlisle to Guards Mill A temporary nose and tail assembly is the abutment to resist the hauling scheme provides the missing also required to be spliced to the main load.

  • The Future of Japan's Tourism
    The future of Japan’s tourism: Path for sustainable growth towards 2020 McKinsey Japan and Travel, Transport and Logistics Practice October 2016 Authored by: André Andonian Tasuku Kuwabara Naomi Yamakawa Ryo Ishida Cover image: The famous torii gate of the Itsukushima Shrine on Miyajima. The future of Japan’s tourism: Path for sustainable growth towards 2020 Preface Japan's tourism industry is on the verge of becoming a major economic engine for the country. In 2020, Japan will host the Olympic and Paralympic Games and enjoy a global platform for its people, culture, and landmarks. Recently, tourism has been positioned as an engine to solve social challenges in Japan and support economic growth. The March 2015 McKinsey Global Institute report, The Future of Japan: Reigniting Productivity and Growth, described how Japan has the potential to more than double its annual GDP growth, to 3 percent, by increasing productivity. This insight is also applicable to tourism, and this report investigates the challenges and potential impact of several initiatives aimed at addressing obstacles to realizing its inbound tourism goals. This report is the result of collaboration between McKinsey’s Japan office and the firm’s global Travel, Transport and Logistics Practice. The research team consisted of Shogo Akimoto, Shohei Ishigami, Minami Maeda, and Yusuke Shimada. We are grateful for the advice and input of many McKinsey colleagues, including Urs Binggeli, Alex Dichter, Masahiro Komatsubara, Diaan-Yi Lin, and Cheryl SH Lim, all of whom provided insight on travel and tourism. For advice on retail and digital, we relied on Tomohiko Funaishi, Ken Kajii, Paul McInerney, and Okaryo Sho.

  • Introduction
    DRAFT Introduction The fame of Oxford Street rests on its enduring appeal as a destination for shopping. Many streets of shops around the world surpass it in cosmopolitan chic, among them Oxford Street’s neighbours in the West End of London, Regent Street and Bond Street. Yet none is so prolonged. Oxford Street runs for well over a full mile in length, both of its sides taken up at ground level almost entirely by shops. Other linear concentrations of retailing certainly exist, as long or even longer. But most serve local needs alone, or have sprung into being only since the coming of the car, whereas Oxford Street’s shops have enjoyed metropolitan, national and international allure for over two centuries. This volume examines how it was that Oxford Street became the most continuously prosperous shopping street not just in London but, arguably, anywhere. In the tradition of the Survey of London, it does so not by advancing an overall hypothesis, but by drawing together the data and details of the street’s history. But a few remarks at the outset may guide the reader. This introduction divides into two main sections, the first on Oxford Street as a road, the second on its shops. Both terms are used broadly and inclusively. The road comes first, because Oxford Street’s function as a means and a focus of communication has always contributed more to its success than the specifics of its built fabric. Three stages in the road’s evolution can be identified. It started out from Roman times as just one section of a major main road in and out of London.

  • Virtualising the Self in the Japanese Mediascape Zen
    Selling Props, Playing Stars: Virtualising the Self in the Japanese Mediascape Zen Yipu A thesis submitted for the degree of PhD Centre for Cultural Research, University of Western Sydney March 2005 For my family Acknowledgements The author is deeply indebted to those who generously helped during the past five years. My discursive thoughts would not have been turned into a cross-disciplinary dissertation without the help of Dr Elaine Lally, who supervised my writing throughout the latter part of my candidacy. Her professionalism was an indispensable element of its completion. Its faults are mine. Professor Ien Ang helped me making a theoretical transition, as well as an institutional one from the Australian National University (ANU) to the University of Western Sydney (UWS). This work would not have materialised without those who shared their time and intellect. For many years since my undergraduate days at the ANU, Professor Geremie Barme gave guidance and inspiration. Dr Mandy Thomas offered generously of her time and support. My time at Canberra School of Art was crucial to my growth. Nigel Lendon and Martyn Jolly showed me the doorway to a journey that eventually led from art to sociology. Many scholars have offered their thoughts. Amongst them Professor Yoshimi Shunya, Professor Tessa Morris-Suzuki and Professor Gavin McCormack gave important clues for this thesis. This work began at the ANU, continued at the University of Tokyo and concluded at UWS. During this time I was supported by an Australian Commonwealth Postgraduate Award and a Japanese Ministry of Education (Monbusho) scholarship – I am grateful for both.
