Use Where
• The new horizontal rail
alignment closely follows the
existing
• Concerns over visual, noise and
disruptions
ONLINE CONSTRUCTION – NORTH, MCKINNON AND CENTRE ROAD
Characteristics
• The main occupation is longer
and has critical construction
activities
• De-risk the main occupation by
minimising the occupation
works

Construction features
• Retention walls built ‘on’ existing alignment consisting of predominately
Continuous Flight Auger (CFA) and Sheet piles.
• CFA piles used except where geometric/environmental constraints dictate
• Sheet piling - utilising the GIKEN ‘silent-piler’
• Props used to minimise pile size
• Piling facilitates main occupation excavation
• Bridges constructed on existing level crossings
• Challenge of a high ground water table
ONLINE CONSTRUCTION – NORTH, MCKINNON AND CENTRE ROAD
![Page 6: Sheet Pile Retaining Walls Design and Construction in ...€¦ · Sheet Pile Retaining Walls Design and Construction in Brown Fields Environment 1 Level Crossing Removal Project 1](https://reader030.vdocuments.us/reader030/viewer/2022040107/5ea605486a1dc622667e89b6/html5/thumbnails/6.jpg)
6
Use Where
• The rail line can be diverted
onto the new alignment i.e.
Requires a larger rail corridor to
work
• Major construction occurs
adjacent the existing rail line
OFFLINE CONSTRUCTION – BURKE ROAD
Characteristics
• Avoids long occupations
• Critical construction activities
can occur without the time
pressure of an occupation

VERSATILE DESIGN
Overhead structures
• Structures kept within the rail corridor
• Avoid site welding where possible
• Non-uniform sheet piles required a
flexible attachment detail
• Two details: top mount and face mount.

COORDINATION OF DESIGN AND CONSTRUCTION TEAMS
• Achieving practical design through
close interaction between design and
construction teams
• Civil, structural and geotechnical
design support on site from early
stages.
• 7 day per week support during major
occupations
• 24 hour design support in 12 hour shifts
during critical construction phase
