The region’s only event dedicated to designing, planning and delivering sustainable bridges
Following the phenomenal success of IQPC’s global Bridges series, including two regional summits, we are delighted to announce the third Bridges Middle East summit will take place under the patronage of Abu Dhabi Municipality and the official support of Ministry of Public Works, Kuwait on 24-27 October 2010 in Abu Dhabi.

  • 1. Qatar-Bahrain Causeway Project Bridges Middle East Conference 2009
  • 2. • Bridges in the region • Qatar-Bahrain Causeway (the latest & greatest) • Design and construction issues • Introduction of rail • Technical challenges Introduction 2
  • 3. Bridges in the Region Bridges Middle East Conference 2009 3
  • 4. Typically: Notably: • Water crossings • Abu Dhabi • Connect population centres • Dubai • Access key infrastructure • Bahrain Bridges in the Region 4
  • 5. Drivers: • Economic growth • Population growth • Urban expansion • Development of major infrastructure • Increasing traffic Bridges in the Region 5
  • 6. Abu Dhabi Sheikh Zayed Bridge Saadiyat Island Bridge (Sheikh Khalifa Bridge) Hodariyat Bridge Bridges in the Region 6
  • 7. Dubai Business Bay Bridge Garhoud Bridge Palm Jebel Ali Crescent Bridges Dubai Metro Sheikh Rashid bin Saeed Crossing (6th Crossing) Bridges in the Region 7
  • 8. Bahrain Sheikh Khalifa bin Salman Bridge Sheikh Isa Causeway Bridges in the Region 8
  • 9. Sitra Causeway Bridges in the Region 9
  • 10. King Fahd Causeway Bridges in the Region 10
  • 11. Qatar-Bahrain Causeway Bridges Middle East Conference 2009 11
  • 12. QBC Project Overview • 40km marine causeway • 2 lane highway in each direction Bahrain • Adjacent high-speed rail facility • 2 dredged navigation channels • 2 high level arch bridges Qatar • 23km bridges / viaducts • 17km embankments • 2 rest area islands • Interchanges, tolling, border facilities Qatar-Bahrain Causeway 12
  • 13. Qatar-Bahrain Causeway 13
  • 14. Design and Construction Issues Bridges Middle East Conference 2009 14
  • 15. Large Marine Site • Pre-cast solution adopted: – To limit offshore operations – To maintain control over quality & safety • Design closely linked to construction methods • Design-Build approach adopted • Allows fast-tracking of schedule Design and Construction issues 15
  • 16. Material: • Volumes required • Need to ensure – Consistent quality – Reliability of supply • High import content • Marine Borrow • Durability considerations Design and Construction issues 16
  • 17. Concrete Durability: Options • Stainless steel • Corrosion inhibitor • Coating • Cathodic Protection • Extent of splash zone Design and Construction issues 17
  • 18. Eurocode: • One of the first projects to use • Europe-wide code for bridge design (road/rail) from 2010 • Option of factored loads or 3rd party checks • Reliability & Consequence Classes Design and Construction issues 18
  • 19. Alignment at Landing Points Influenced by: • Archaeology (Qatar) • Competing land use (Bahrain) • Stakeholder Requirements Design and Construction issues 19
  • 20. Qatar Landing Point Design and Construction issues 20
  • 21. 3 km Design and Construction issues 21
  • 22. Design and Construction issues 22
  • 23. Introduction of Rail Bridges Middle East Conference 2009 23
  • 24. Introduction of Rail Concept design: • Road only • Twin deck viaducts • 80 m viaduct spans • Cable-stay bridges over Navigation Channels Introduction of Rail 24
  • 25. Impact of Rail • Larger vertical and horizontal loads – Freight • Limitation on gradient and horizontal curvature – High-speed passenger • Extended Schedule Introduction of rail 25
  • 26. Resultant changes to concept design: • Vertical and horizontal alignments revised • Length of viaduct increased • Stronger, stiffer structures • Arch bridges replaced cable-stayed • Closer pier spacing • Twin road decks combined • Navigation Channel relocated Introduction of rail 26
  • 27. Technical Challenges Bridges Middle East Conference 2009 27
  • 28. Environmental • Zero impact on hydraulic flows • Extensive baseline measurements • Ongoing Monitoring • Constraints on construction methods Technical challenges 28
  • 29. Quality & Safety • Remote sites • Working at height • Heavy lifts • 24/7 working • Cost-driven schedule • Motivating the workforce Technical Challenges 29
  • 30. Rail Issues • Axle Load • Bahrain Network • Speeds • Qatar Network • Height Clearance • GCC Network • Emergency Escape • Maintenance Access Technical Challenges 30
  • 31. Dredging of Navigation Channels • Unsuitable material • Creative disposal Ship impact on Main Bridges • Designed to deflect • Seismic resistant • Visual Impact • Technical challenges Technical challenges 31
  • 32. Settlement of Embankments • Soil improvement & testing • Deferred rail solution • Ballasted track High Voltage Interconnect • Three 220 kV circuits • Two 400 kV circuits Technical challenges 32
  • 33. In Conclusion • Rich heritage of major bridges in the GCC • The Qatar Bahrain Causeway will enrich this heritage • First high-speed rail crossing • Numerous challenges to overcome • A landmark project for the Region Concluding remarks 33
  • 34. Thank You 34
