Collaborative teamwork vital to success
The SRL project is a hugely complex disaggregated program of work with multiple interactions between packages. The Initial and Early Works package has critical interfaces with the two Tunnelling Packages (Major Works) which progressed through procurement in parallel with the implementation of Initial and Early Works design development.
SMEC were able to provide not only key designers for the project, but also turnkey integrated modelling, including:
- CAD/Digital Engineering
- 12d design
- Flood and hydrogeology modelling
- Traffic modelling (road and specialist VISSIM tram interface modelling).
With Laing O’Rourke, SMEC and Arcadis continue to work closely with SRLA to deliver change and additional services to simplify the interfaces between packages, address key issues and ensure a smooth transition from Initial and Early Works and Major Works. These changes include, amongst other things:
- Minimising any service relocation for Major Works
- Design refinement for the tunnel access shafts
- Developing design for the TBM Bulk Power Supplies
- Supporting the inclusion of innovative Tunnel Access Structures and associated design development.
Key milestones
SRL East will be open by 2035, delivering better transport connections, slashing travel times and creating a pipeline of jobs and training opportunities.
The design of the Initial and Early Works has been specifically prioritised to ensure a smooth transition from Initial and Early Works and Major Works. Specifically, the two Tunnel Access shafts will be completed in accordance with the Major Works need.
The inclusion of TBM Bulk Power Supply design will also enable the Major Works contractor to essentially ‘plug and play’ with the TBMs when they are delivered to site.
In a key sustainability milestone, all flood and hydrogeology modelling were required to consider the project impact, given the current climate challenge and with a 100 year lookahead.
