Design and Construction Issues


      Bridges Middle East Conference 2009



                                            14
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
Material:
• Volumes required
• Need to ensure
   – Consistent quality
   – Reliability of supply
• High import content
• Marine Borrow
• Durability considerations


             Design and Construction issues   16
Concrete Durability: Options
•   Stainless steel
•   Corrosion inhibitor
•   Coating
•   Cathodic Protection
•   Extent of splash zone




Design and Construction issues   17
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
Alignment at Landing Points

Introduction of Rail


Bridges Middle East Conference 2009



                                      23
Introduction of Rail

Concept design:
•   Road only
•   Twin deck viaducts
•   80 m viaduct spans
•   Cable-stay bridges over
    Navigation Channels




                   Introduction of Rail   24
Impact of Rail
• Larger vertical and horizontal loads
    – Freight
• Limitation on gradient and horizontal curvature
    – High-speed passenger
• Extended Schedule




                Introduction of rail                25
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

• Unsuitable material
• Creative disposal


Ship impact on Main Bridges
•   Designed to deflect
•   Seismic resistant
•   Visual Impact
•   Technical challenges



                   Technical challenges   31
Settlement of Embankments
• Soil improvement & testing
• Deferred rail solution
• Ballasted track


High Voltage Interconnect
• Three 220 kV circuits
• Two 400 kV circuits
