  • Initial Transport Assessment of Development Options
    This subject paper is intended to be a research paper delving into different views and analyses from various sources. The views and analyses as contained in this paper are intended to stimulate public discussion and input to the planning process of the "HK2030 Study" and do not necessarily represent the views of the HKSARG. WORKING PAPER NO. 35 INITIAL TRANSPORT ASSESSMENT OF DEVELOPMENT OPTIONS Purpose 1. The purpose of this paper is to provide information on the reference transport demand forecasts, assessment of Reference Scenario and framework for option evaluations. Background 2. Under Stage 3 of the HK2030 Study, Development Scenario and Development Options are formulated. The Development Options are then subject to transport, economic, financial as well as environmental assessments. Under the integrated approach adopted for the Study, the transport requirements identified for the Development Options are also assessed in terms of the environmental, economic and financial implications in order that a meaningful comparison of the Development Options could be made. 3. Under the Reference Scenario, various development choices have been considered to satisfy the land requirements. They can broadly be categorised into two different options of development patterns, namely Decentralisation and Consolidation. The details are presented in the paper on Development Options under the Reference Scenario. Assessments have been carried out to identify the transport requirements of the two Development Options in 2010, 2020 and 2030. The findings are summarised in the following sections. Development Options 4. Under the Reference Scenario, the population in 2030 could be in the region of 9.2 million which is only marginally more than the population of 8.9 million for 2016 adopted in the previous strategic planning.

From the earliest project phases until the end Chief Executive Officer of a structure’s life, VSL’s experts provide consultancy and engineering services that produce cost-effective, durable and sustainable solutions for our clients. The life of any structure is divided into three key phases: planning, construction and maintenance. VSL’s engineers are of invaluable support to designers carrying out feasibility studies at the planning stage, and, if relevant, can propose alternative solutions to achieve what is best for the project. How to build the structure becomes the critical issue once the design is optimised and here VSL’s teams take up the challenge to ensure fast-track and safe construction. Monitoring of structural behaviour may be required either during construction or later, when the structure is in service, in order to forecast maintenance works and allocate the corresponding budgets. In each case, our experts respond to the requirements by providing a monitoring system that is adapted to the needs and economic constraints. Once the inspection plan has been established, VSL can also handle any corresponding strengthening and repair works required. True turnkey and full-scope projects covering all phases of a structure’s life are at the heart of our business.

  • Integrating Bridge Structural Health Monitoring and Condition-Based Maintenance Management
    Civil Structural Health Monitoring Workshop (CSHM-4) - Lecture 06 Integrating Bridge Structural Health Monitoring and Condition-Based Maintenance Management Y.Q. NI*, K.Y. WONG** *Department of Civil and Environmental Engineering, The Hong Kong Polytechnic University, Hong Kong ([email protected]) **Highways Department, The Hong Kong Special Administrative Region Government, Hong Kong Abstract. The development of structural health monitoring (SHM) technology has evolved for over fifteen years in Hong Kong since the implementation of the “Wind And Structural Health Monitoring System (WASHMS)” on the suspension Tsing Ma Bridge in 1997. Five cable-supported bridges in Hong Kong, namely the Tsing Ma (suspension) Bridge, the Kap Shui Mun (cable-stayed) Bridge, the Ting Kau (cable-stayed) Bridge, the Western Corridor (cable-stayed) Bridge, and the Stonecutters (cable-stayed) Bridge, have been instrumented with sophisticated long-term SHM systems. These SHM systems mainly focus on the tracing of structural behavior and condition of the long-span bridges over their lifetime. Recently, a structural health monitoring and maintenance management system (SHM&MMS) has been designed and will be implemented on twenty-one sea-crossing viaduct bridges with a total length of 9,283 km in the Hong Kong Link Road (HKLR) of the Hong Kong – Zhuhai – Macao Bridge of which the construction commenced in mid-2012. The SHM&MMS gives more emphasis on durability monitoring of the reinforced concrete viaduct bridges in marine environment and integration of the SHM system and bridge maintenance management system. It is targeted to realize the transition from traditional corrective and preventive maintenance to condition-based maintenance (CBM) of in-service bridges.

  • Major Bridge Development in Hong Kong – Past
    https://doi.org/10.2749/222137809796089278 Recent Major Bridges 1 Major Bridge Development in Hong Kong-Past, present and future Michael CH HUI Doris MS YAU Chief Engineer Engineer l Highways Department, =- Highways Department, 1,-' HKSAR, China ' HKSAR ' China mchhui@graduate. hku. hk [email protected] Michael CH Hui, received his S Doris Yau, received her BEng B. Sc ( Eng) from the University from the University of Hong of Hong Kong, MSc ( Bridge En­ Kong, MSc from the Hong Kong gineering) from the University of University of Science and Surrey and PhD from the Tongji Technology. University Summary The first "modern" type of vehicular bridge was built in Hong Kong in the 1920s. The need for an efficient transportation system to cope with population growth and enable eco­ nomic development has demanded the construction of more and more bridges since the middle of the 20th century. By 2007 , Hong Kong had a total of about 1 300 vehicular bridges. Four of these bridges, including the Tsing Ma Bridge, Kap Shui Mun Bridge, Ting Kau Bridge, and the cable-stayed bridge on the Hong Kong-Shenzhen Western Corri­ dor, are considered to be major bridges supported by cables. Currently, the Stonecutters Bridge on Route No. 8 is under construction and is expected to be completed in late 2009. At the same time, the Hong Kong-Zhuhai-Macau Bridge will be in its detailed design stage soon. Whilst efforts have been made by bridge builders to construct these giant structures, the upkeeping of these valuable assets at a high standard and ensuring their continuous functioning and performance during their intended lifespans will be another important task for bridge engineers.
