08:30 Chairman’s opening

Maximising piling design technologies

08:45 Results of implementing small-diameter micro piles and anti-heaving piles

• Understanding the benefits of selecting a hollow steel tendon tube and grouting conduit combination
• Comparing a combination solution to traditional system performance, design criteria for EN standards
• Ensuring quality through corrosion protection to ensure a sustainable foundation structure

Speaker to be confirmed

09:30 Behaviour of large-diameter bored piles in different subground conditions

• Outlining piling and deep foundation for heavy structures
  • Piled raft as an economic innovative solution for high rise buildings, bridges and transition zones between embankments and bridges
• Analysing pile load tests on large diameter bored piles in different soil and rock conditions
• Taking lessons learned from completed projects and showcasing planning aspects, economical design features, design concepts, construction features, performance, quality control and quality assurance

10:45 Screw piling and the applicable scenarios for adopting the method: meeting construction schedules

• Piling, underpinning and anchoring to solve foundation problems
• Analysing load test results
• Highlighting specific projects that adopted the approach and the reasons why

Speaker to be confirmed

11:30 PANEL DISCUSSION: Improving the quality of piling and deep foundations in Sub-Saharan Africa

• Investigating pile behaviour throughout Sub-Saharan Africa including load capacity and settlement characteristics
• Site investigations and modes studies on silica soils and work in calcareous-barbonate sediments
• Selection, analysis and design of pile and piled raft foundations and shoring systems for towers

13:15 Design and performance of a piled raft foundation

• Understanding the concept of a piled raft foundation and its ability to improve performance
• Analysing the design of a piled raft foundation
• Ensuring successful FE modeling of a piled raft foundation
• Implementing piled raft foundations

14:00 CASE STUDY: Large-diameter piles in dolomites for the Gautrain project

• Understanding the benefits of large-diameter bored piles in dolomites
• Assessing the scope of work and dealing with sinkholes
• Addressing pile drivability issues
• Overcoming environmental concerns in soft soil foundations

15:30 CASE STUDY: Deep foundations and piling on the Zambian Copper Belt

• Weathered sub-tropical soils (saprolitic) from 25 to 80m overlying granite or conglomerate rock
• Shaft sinking is problematic in these materials particularly for large headgear loads
• Solution is a combination of lateral support and load bearing piles
• Piling equipment in remote areas may be able to achieve the design
• Innovative design using available equipment is sometimes necessary
• The aim is to build a competent deep foundation at depth
• This case study reports on the approach, redesign, construction and verification

16:15 CASE STUDY: Overcoming inadequate pile capacity for a 65 storey building

Patrick Wong from Coffey Geotechnics, Australia will provide an assessment of the load test results on as constructed piles that are designed to support a 65 storey tower in Vietnam. “Soft toe” behaviour was found and this was assessed to be due to poor construction technique. Patrick will discuss the challenges of designing cost effective remedial works to enable successful completion of the project.
