This workshop is organised for the 7th time in consideration of good response in 2010, 2011, 2012, 2014, 2016 & 2018. It aims to present and discuss systematically the geology of Singapore, as the Geological Map of Singapore has been updated from the old version published in 1976 and a new Stratigraphical Framework will be introduced to the industry in this workshop. The Economic Strategies Committee (ESC) of Singapore recommended the development of underground space over the next decade as the Government continues to find ways around the problem of space limitations in land-scarce Singapore. With an increasing demand of deep excavation, tunnelling and development of underground rock cavern space in Singapore, it is important for regulators, planners, developers, engineers and contractors to have a more comprehensive understanding of Singapore geology, the use of updated Singapore Geological Map and the planning for geologic investigations. This workshop brings together experts and practitioners from Singapore to share their knowledge and experience.

Lecture Title: SUPERCON - Sprayed Sustainable Permanent Robotized Concrete Tunnel Lining


The SUPERCON proposal is a counterweight to a trend in Norwegian tunnelling projects towards adopting the "European way" of tunnelling, with in-situ casting or pre-cast segment lining. SUPERCON aims at producing thin sprayed concrete layers with the quality to act as temporary support during construction and permanent lining over the service life of tunnels. The primary objective is to provide the tunnelling industry with the required knowledge to produce Sprayed sUstainable Permanent Robotized CONncrete tunnel linings, which meet modern demands for functionality, sustainability and eco-friendliness in new infrastructure projects, without compromising the environment. Improvement of robustness and durability shall reduce cost and environmental loads for the public infrastructure owners.

Lecture Title: Fibre Reinforced Sprayed Concrete: Testing & Performance Criteria

The mechanisms through which FRSC (Fibre Reinforced Spray Concrete) controls deformations and absorbs energy are complex, involving technicalities of both the spray concrete process and the fibre properties. Multiple performance criteria are proposed : flexural strength, residual flexural strength after cracking, energy absorption (toughness).Toughness is generally the main criterion for FRSC as ground support. This presentation will underline, as mentioned in the European standard EN 14487-1, the different ways of specifying the ductility of FRSC in terms of residual strength and energy absorption capacity. Major results on a research project undertaken at Roma, Laval and Bochum University will be presented to evaluate the EFNARC three point bending on square panel with notch to determine the residual strength and the performance criteria proposed according to Model Code 2010.

Lecture Title: Final Sprayed Concrete Linings for Functional Permanent Rock Support and Water Proofing

Sprayed concrete in combination with rock bolts has been used successfully for decades as a permanent rock support lining system in hard rock conditions. However, the required functionality of the final lining for a modern rail or road tunnel implies more than rock mechanical stability. A permanent and durable waterproofing is also required.  Sprayed waterproofing in the form of a double bonded polymer based membrane has proven to be a feasible technical solution to make a sprayed concrete lining waterproof without the use of cast concrete or shield or segmental waterproofing systems. The most important results of the research findings for waterproof SCL as well as an outline of ongoing and planned further research will be presented.

UTT Regional Manager (Asia Pacific), Mapei Far East Pte Ltd

Lecture Title: New Technologies for Shotcrete

The R&D laboratories of Mapei S.p.A are working every day on the formulation of new products with low environmental impact. Enrico Dal Negro will show the newest MAPEI technologies for shotcrete. Mapei S.p.A. is developing Innovative polymers for the formulation of an eco-friendly shotcrete with low emission of carbon dioxide. A “green shotcrete” which allows to use less cement than a standard shotcrete. Concrete is the second material after water mostly used in the world; it has a strong impact on our planet, in terms of GHG emissions (Greenhouse gases, which cause the climate changes we are living in our age) and in terms of Fossil Abiotic Depletion. One cubic meter of concrete can emit more than 250 kg of CO2, mainly coming from the cement. 1 kg of grey cement, during its whole life cycle, from the raw material extraction to the gate of the plant, can emit ~ 0.9 kg of CO2. That’s why decreasing the amount of cement in the mix design can give a very strong contribution to the reduction of CO2 emissions and consequently to the Global Warming.

Lecture Title: Use of Shotcrete and Rock Bolts in the New Austrian Tunnelling Methods

Shotcrete technology has been intrinsically linked with the development of the New Austrian Tunnelling Method (NATM) since the 1950’s. Its unique properties have set the path towards efficient and flexible support application, making it an indispensable element of modern tunnelling while pushing the limits of applications over the decades. The presentation will focus on design aspects of shotcrete for different applications in tunnelling, as well as giving a historical retrospect on various developments and their consequences on tunnel design using case histories from major underground infrastructure projects in Europe and around the globe. An overview of application in various types of tunnelling projects, the relevant design aspects for underground infrastructure projects as well as recent technological developments and trends will be presented. 



Norwegian Geotechnical Institute, Norway

Lecture Title: Reinforced Ribs of Shotcrete (RRS) as Permanent Rock Support - Development and Recent Experience

Reinforced Ribs of Shotcrete (RRS) is one of the suggested rock mass support methods in the Q-system. The method was not included in the original Q-system from 1974, but was gradually introduced in the late 80s/early 90s as an alternative to cast concrete lining as a permanent rock support in Norway. In 1993 the Q-system was updated, and RRS became one of the standard solutions for rock support whilst being introduced internationally. RRS used in very poor rock mass are load-bearing while RRS used in better rock mass reinforce the rock mass. In the middle of the 2000s, some RRS were instrumented to analyse the load from the rock mass. One saw that there were no major loads on the arches in these few cases. RRS is a flexible system, which can be easily applied to different rock mass qualities and to both minor tunnels and larger rock caverns. The history and the use up to date will be presented.
