Title: Challenges On Soft Ground and Solutions
Soft compressible alluvial clays are found in the coastal belt of Malaysia, particularly in the West Coast of Peninsular Malaysia and Sarawak. Some of the challenges faced by development over this formation include differential settlement of roads, highways, railways and building platforms. Serious issues such as failures of bridge approaches and deep excavations may occur if these soft compressible alluvial clays are not properly dealt with. The presentation will include findings from forensic investigations into cases of differential settlements and failures, and solutions to some of these challenges are provided.

Title: Roles of Pavement Technologies in Sustaining Humanity
Human civilization is dependent upon how well a society is developed. This is much influenced by a good road network and sound pavement structure. Pavement technologies have evolved to mainly suit the needs, however, oftentimes inappropriate selection of technologies have resulted in poor performances that lead to an unnecessary increase in maintenance cost, riding quality and safety. Locations with rain throughout the years should adopt porous pavement technologies. Failure to do so could lead to hydroplaning and accidents. Heavy industrial areas use superior quality of mix such as Stone Mastic Asphalt, and high trafficked roads need concrete pavement for long-lasting performance to avoid traffic congestion. To help reduce carbon footprint, warm mix asphalt would be a better choice. Taking these factors into account during planning and design could not only make pavement long-lasting but also save humanity.

Title: Empowering the Readymix Concrete Industry with Advances in Concrete Technology
The first ready-mixed concrete was used in the United States of America more than a hundred years ago. Since then, the readymix concrete industry has been developing to become the industry that consumes more than half of the cement produced today. The readymix concrete industry has benefitted from the development in concrete technology in enhancing the end product and this relationship is inevitable for the betterment of both entities. To date, cement is partially or totally replaced by other cementitious materials such as ground granulated blast-furnace slag (GGBS), pulverized fuel ash (PFA), micro- or nano-silica, metakaolin, etc. These cement-replacement materials are incorporated in concrete either to improve or modify the properties of concrete to suit specific application. Another advancement in concrete technology is the admixture technology. The development in admixture technology lead to production of various types of high-performance concrete. For instance, the use of high-range water reducer and viscosity-modifying agent lead to consistency in producing high-flow or self-compacting concrete. Other than cement-replacement materials and admixtures, fibres have also been used extensively in concrete to improve its tensile stress resistance. Steel and polymer fibres are the most common types used but the exploration of using natural fibres is also in existent. With the current emphasis in industry revolution 4.0 (IR4.0), automation in the readymix concrete industry is also inevitable in the near future as concrete mix design has become more complicated due to the ever-growing list of materials. Therefore, the application of computational intelligence may be the future solution for the concrete mix design. Another automation technology that may have an impact on the readymix concrete industry is 3D printing, of which a small house can be built within a day. For a better future in the readymix concrete industry, a stronger link between concrete technology development and ready-mixed concrete production can always be enhanced through closer university-industry engagement.

Title: Driving Forces in Global Construction: Infrastructure, Technology and Sustainability
Increasing urbanization throughout the world is placing high demands on the cities of the world to increase capacities of their infrastructure. Infrastructure systems involving roads, highways, ports, power supply, and water supply all are in need to be newly built or upgraded. The demands on their size, scale, quality of service and maintenance are ever increasing. In addition, infrastructures need to be sustainable and resilient. Modern technology, such as automation, Internet of Things, artificial intelligence, and the likes offers a great opportunity to build and maintain infrastructures to meet these demands and needs. This keynote paper is to address the challenges and opportunities facing the civil engineering community of today. While the demands are enormous and daunting, the opportunities abound, too. In this paper, first the state of global construction will be discussed, with particular focus on infrastructure construction in the wake of increasing urbanization. Second, the importance of sustainability and resilience will be addressed, and finally, the role of technology in building safe, sustainable and resilient infrastructure will be outlined. The underlying message of the paper is that the civil engineering community at all levels firm, industry and government must consider the new challenges of infrastructure construction and embrace modern digital technology as opportunities to meet the challenges.
