EIC has recently provided a broad range of design services to the CIMIC Group companies. Some examples are given below.
West Gate Tunnel – Bridge 91 (VIC)
EIC carried out the design of both the construction engineering and associated major temporary works for a curvilinear shared path cable-stay bridge for the West Gate Tunnel project in Victoria. EIC’s design services included a detailed analysis of the bridge during construction to ensure the structure is not overstressed and the design of temporary towers, support frames and beams required for staging.
Metronet NEWest Alliance (WA)
EIC conducted value engineering and temporary works design for the duplication of Mandurah lines and the extension of the Joondalup Line in Western Australia. EIC was involved in the design optimisation for retaining wall, bridge and station structures, and the design of high-risk temporary works including working platforms, rail crossings and excavations adjacent to critical structures.
Cross River Rail RIS (QLD)
EIC undertook the detailed geotechnical design and independent verification for both temporary and permanent works for the Cross River Rail RIS project in Queensland. The design tasks delivered by EIC included bridge, building and OHLE foundations, construction platforms, retaining structures and earthworks. EIC was also responsible for the interpretation of geotechnical conditions.
M6 Stage 1 (NSW)
EIC provided a range of design services for the Transport for NSW M6 Stage 1, covering both temporary and permanent works. EIC’s services range from essential temporary works design, including site establishment, temporary hoardings and fences, to high-risk complex design tasks such as the concept of a binocular shaft replacing a conventional rectangular shaft and tunnels constructed in soft ground with high earth and groundwater pressure.
North South Commuter Rail Package 3B Tender (Philippines)
EIC delivered the design for the North South Commuter Railway tender in the Philippines. EIC’s design services included excavation support for a metro station, ground support for underground passageways and TBM cross passages and openings. EIC successfully delivered the tender design within a very short tender period and incorporated relevant construction methods into the design.
