Session OneEffectively managing structural design issues while correct-ing ground settlement in deep excavationDeep excavations in urban areas have the potential to cause unfavourable effects on ground stability and nearby structures. In this session the speaker will explore the following key elements: • Setting up monitoring instruments to control and monitor the overall structural issues during the construction of retaining walls, main excavations, and when groundwater is involved• Using BIM to integrate and visualise monitoring data for risk assessments during urban deep excavation projects• Assisting construction project teams in identifying and understanding possible blind spots when attempting to achieve risk assessments Dato’ Ir Dr. Gue See Sew Chief Executive OfficerG&P Professionals Sdn Bhd

Session TwoMonitoring for the design and construction of deep excava-tions and tunnels-Case StudyThe design of deep excavation and tunnels necessarily rely on certain assumptions as the variability of ground conditions can never be certain in advance of construction. Therefore in order to validate assumptions monitoring is an essential requirement for geotechnical works. The presentation will explain how monitoring was used in the design and construction of the deep excavation at Ho Man Tin station to validate the design of the first use of GFRP soil nails in Hong Kong in an area of complex geology. Ir. Leslie Swann DirectorJacobs China Limited, Hong Kong

Session Three: Panel DiscussionEngineering in Dif�cult Ground Conditions? Gauging new developments in TBM and other excavation methods for changing grounds Tunnel boring machines (TBM) are increasingly used for tunnelling with difficult and complex geological conditions, including rock and soil mixed and interfaced grounds, spalling and bursting rocks, squeezing and swelling grounds, blocky and highly fractured rocks, fault and shear zones, and grounds under high in situ stress and water pressure. Hear from our panel of speakers as they discuss the new methods which can increase the efficiency of excavation in such conditions.Panelist:John Endicott Geotechnical & Engineering Tunneling AsiaAECOM, Hongkong

Chris Dulake Engineering DirectorHS2, United Kingdom

Session FourImplementing of Intelligent Models of Optimization for Tunnel Blasting DesignsThis session seeks to discuss how the adoption of Genetic Algorithm (GA), which is widely used over the world for analyzing and optimizing different engineering problems, to optimize the blasting parameters to improve the blast performance for tunnel blasting when excavating a tunnel with limited blast vibration constraints. There are more than 100 sensitive receivers of different aspects such as building structures, utilities services and geotechni-cal slope features. Using the genetic algorithm for optimization, it is discovered that the Powder Factor for a tunnel blasting could be optimized to its maximum value within the pre-defined vibration limit so that the explosives charge weight will also be maximized for a blast with different tunnel profiles.Lawrence TH Lee Senior Construction Engineer-CivilMTR Corporation Limited, Hongkong

Session SixIntegrating geotechnical risk management and project risk management for achieving project objectives within time and budgetThe segregation of geotechnical risk management and project risk management within project organization is likely to obstruct the catchment of all potential risks management benefits, in terms of improved safety and quality, cost and time savings. Geotechnical risks need to be integrated with overall project risk to be better managed. This session seeks to develop a robust ground models and the associated management of identified hazards and geotech-nical risks which is crucial to effective delivery of construction and civil engineering projects.Speaker to be advised

Afternoon refreshments

Session Seven: Panel DiscussionGauging the effectiveness of Geotechnical Baseline Report (GBR) in managing contractual litigationUsing of Geotechnical Baseline Report (GBR) for contractually defining anticipated ground conditions has become a widely accepted practice in tunneling industry. The significant and critical nature of these reports have increased the scrutiny they received to unprecedented levels. Hear from our panel of speakers as they discuss and provide suggestions of improving the effectiveness of GBR based on their collective experience with many tunnel projects and their GBRs.Panelist:John Endicott Geotechnical & Tunelling AsiaAECOM, Hongkong

Session EightBored tunnelling in urban environment: Existing tunnel movements due to close proximity - What is the major problem? and How to effectively tackle it?With the growing population, the need for TBM tunnels in urban environment has continuously increased in the last decade. The need for TBM tunnels is not only limited to urban transportation but is also constantly increasing for other key infrastructure elements, which results in new tunnels constructed close to existing tunnels / other infrastructure. This presentation will focus on the problems/risks associated with tunnels driven in close proximity and how to assess/quantify the impact. A case study from Thomson East Coast Line is considered to illustrate the impact assessment and risk evaluation. Senthil Nath GT Senior EngineerGeoconsult Asia Singapore Pte Ltd, Singapore

Session NineHorizontal Directional Coring (HDC) for Subsea Tunnels - Case Study Hong Kong Deep Sewer TunnelsSite investigation for tunnels can be a problem. All too often budgetary restrictions result in insufficient information about the ground before tunneling. Horizontal Directional Coring (HDC) can be used to obtain nearly continuous cores close to and parallel with the alignment of the tunnel. Used in conjunction with other site investigation, HDC can provide quality ground models for reason-able anticipation of ground conditions to be encountered during tunneling.John Endicott Geotechnical & Engineering Tunneling AsiaAECOM, Hongkong

Session FiveSelecting the appropriate carven excavation method in urban areasTunnel design and construction requires the use of appropriate techniques and technologies during all phases of a tunnel project. Selecting appropriate excavation method for large span urban tunnel projects in soft ground is a key factor for successful comple-tion of the project.Eric Chiu Divisional Director and Head of Tunnels and Ground EngineeringATKINS, Hongkong

Session SixGround Water Ingress into Caverns: A case study of hydro-geological assessment for West Island Line Sai Ying Pun Station, Hong Kong will demonstrate the allowable water ingress to reduce risk of short term and long term ground movement In underground hard rock construction, ground treatment is normally limited to installation of support to provide stable ground and safe working conditions. Groundwater ingress control is necessary to prevent surface settlement and damage, or environ-mental impact to vegetation and groundwater resources. Hear from the most relevant projects in Hongkong which shows the most important of high-pressure Pre-Excavation Grouting (PEG) for the purpose of achieving targeted minimum residual groundwater ingress into tunnels and caverns in hard rock.Speaker to be advised

Afternoon refreshments

Session SevenQuantifying geological risk for underground development of tunnels and cavernsGeological and geotechnical uncertainty presents an inherent risk to the tunnelling and cavern development projects .The uncertainty is reduced by geotechnical investigations and engineering experi-ence in similar ground conditions but even with the most detailed investigations, the uncertainty can never be eliminated and therefore it is important to assess what level of risk remains. The process involves using sensitivity analyses to assess impacts of key geological parameters followed by assessments of the likely statisti-cal variance in those parameters to make probabilistic predictions of negative, as well as positive, impacts from those parameters. Some of the parameters discussed here, include rock head level, Q number variation and permeability. Andrew Forsythe Principal Engineering GeologistMott MacDonald, Singapore

Session EightRevolution in sensor technology: Innovative and smart monitoring tools in rock behaviourTechnological innovation can advance engineering practice and increase the appeal of underground space.
