1 Half-day Seminar 2 June 2012 (Saturday) Advanced Technologies and Equipment for Construction of Transport Infrastructure Background The Chartered Institution of Highways and Transportation (CIHT) is a learned society concerned specifically with the planning, design, construction, maintenance and operation of land-based transport systems and infrastructure. It aims to provide a forum for the exchange of technical information and views on highways and transport policy; to provide specialist advice to government and other bodies; to make roads safer for the travelling public; and to encourage training and professional development to meet today's requirements. Every year CIHT Hong Kong Branch organises a half-day seminar to provide a platform for academics, professionals and other interested parties to exchange views on selected technical topics. Professionals and students from University, Consultant and Contractor, as well as those related to transport or highway industries, will be invited. Theme Hong Kong has one of the most successful transport systems in the world, with around 2,000km of highway and 240km of railway. To cope with the growth in population and economy, the Government have been planning and implementing new roads/highway as well as passenger railway. During implementation, there are challenges such as working in confined space or busy life traffic, tight construction programme, and satisfying the requirement of different stakeholders. To overcome challenges, contractors make use of different high technology or equipment so that the projects can be implemented at a quicker pace, at a safer and more environmentally friendly manner. The theme of this half-day seminar Advanced Technologies and Equipment for Construction of Transport Infrastructure aims to introduce how contractors overcome the construction constraints by making use of the latest technologies and construction plants. This seminar would be useful for both engineers and contractor to recognize the latest development of the construction technologies and construction plants and equipments. The speakers will give a brief account on the problems they are/will be facing and how they implement the construction works with the aids of various technologies and plants. It is meant to be an interesting and practical seminar in which project implementers will share their invaluable experience of construction of major transport infrastructure in Hong Kong and overseas. 1

Theme 1 High Precision Drilling in Urban Areas Synopsis: For construction of underground road or rail tunnels close to existing house, tunnels or other sensitive objects, blasting will cause vibration which are unpleasant and may lead to safety concerns. Therefore, to blast in hard competent rock close to sensitive areas, it is necessary to have very good control on the quantity of the explosives, and on the location where the explosives are placed. To make each blast efficient and effective, we must have good control on the quantity of explosives, and how they are distributed in terms spacing and pattern of each of the drill holes. During the last few years, the quality and precision on drilling rigs attract a lot of attention. To achieve high precision drilling, computerized drilling rigs are used. The advantage of using this type of rigs is with high degree of precision in terms of where to drill, verses any previous drills. During the last years the focus has been on raising the quality and precision on the drilling rigs. Today, with the computerised and automatic drilling technology, contractors can fully master the design of drilling patter, navigation or positioning the drill rig, executing of drilling and logging of the rounds, bringing the precision in tunnelling to a new era. Keywords: High precision drilling Speaker: Mr. Anders Ö stberg, Atlas Copco China / HK Limited Mr Anders Ö stberg have broad experience on civil works. He has worked in both rural and urban areas of different parts of the world. His experience ranges from being the leader for tendering jobs 4

5 to on-site construction management. In October 2011, Mr Ostberg joined Atlas Copco as a tunnelling application specialist. Theme 2 Piling Methods and Equipment for Highway and Railway Projects Synopsis : Highway and railway construction projects, unlike land piling, often involve foundation works of a wide spectrum ranging from diaphragm wall, mini-piles to marine piles. The associated site condition also varies greatly from spacious sites for depot piling to extremely confined area in the immediate vicinity of live traffic or operating railway tracks. Given these, works planning often presents great challenges to foundation contractors, in terms of equipment selection and construction method, so as to meet works programme while satisfying safety and environmental objectives. This paper describes the current piling technologies applied in highway and railway projects. A review of the latest development in piling equipment and techniques will be presented. Methods and approaches to deal with constructability, site constraints and safety issues will be discussed and highlighted with case studies. Keywords: piling, method, equipment, constraints, constructability, safety Speaker: Ir Dr. Alan Wan, Gammon Construction Limited Ir Dr Alan Wan is a Senior Project Manager at Gammon Construction Limited. He was educated in the UK and Canada and has over 15 years of experience working as contractor in the design, construction and project management of heavy foundation projects. Notable projects undertaken by Ir Dr. Wan include the Hong Kong-Shenzhen Western Corridor, Castle Peak Road Improvement, Central Reclamation Phase III, KCRC HCC 300 and 301, MTRC Contract TKE 609, WIL 704 and 705, and XRL 811B. Theme 3 Technology and Equipment for Ground Freezing Method Synopsis: These two sections of the CWB will be constructed by traditional cut-and-cover method, top-down in part after the bare minimum allowable reclamation and ELS diaphragm wall construction. While this paper will talk about the construction methods of the above major activities under the particular site and contract limitation such as maintaining the existing public marine traffic and complying with all statutory environmental requirements, it will also touch on the re-provisioning of existing facilities along the shoreline such as cooling water system, drainage outfall which forms a great challenge to the planning and execution of the project.

His main expertise is ground freezing and he has worked in Japan and Taiwan for famous projects, one of those is the Tokyo bay crossing expressway. Mr. Ricky K. N. Wong is from Hong Kong and has joined Sanshin Corporation since Mr. Wong has worked on projects in Japan, Taiwan, Hong Kong, Singapore and Thailand and is now responsible for the company s business in the Southeast Asia. 5

6 Theme 4 Technology and Equipment for Bridge Construction Synopsis: Precast Segmental Bridge construction is nowadays the most common method adopted in the construction of multiple span concrete structures for roads and railways. The technique of precasting concrete box girders in short segments by the match casting method and transporting them to site to be lifted into position is well established and offers many benefits. This paper presents different techniques of erecting segments by the balanced cantilever or span by span method. For the balanced cantilever method, the segments are joined on either side of the pier in a symmetrical operation supported by either a self-launching overhead gantry, deck mounted lifting frames or by cranes. For the span by span method, all segments for one span are supported by either an overhead or underslung gantry or alternatively by a ground supported system, and joined together in one operation to make a complete span. Keywords: precast segmental, balanced cantilever, span by span, launching gantry, lifting frame Speaker: Mr Christian Venetz and Mr. K H Lai, VSL Intrafor HK Limited Mr Christian Venetz is a Design Manager of VSL Hong Kong Limited and holds a regional role as Technical Officer of North Asia reporting to VSL Technical Committee.

Mr K H Lai is the Director and General Manager of VSL Hong Kong Limited. He has worked in post-tensioning and related engineering fields for over 20 years and has been involved in various building and civil projects in Hong Kong. Theme 5 Different Tunnel Boring Machines for Varying Ground Conditions Synopsis : In the past 20 years, the tunneling projects around the region became more and more sophisticated. Technology for Tunnel Boring Machines (TBMs) has been developed to make tunnel construction possible today, which were not in the past. TBMs facilitate safe and reliable tunneling methods. They also enhance planning reliability and better compliance of construction accuracy and costs.
