Legacy Way - Procurement

The Legacy Way (formerly Northern Link Tunnel) is the fourth of five components of the Brisbane City Council’s TransApex Project. The project involves two bored tunnels carrying two lanes of traffic in each direction from the Western Freeway in Toowong to the Inner City Bypass at Kelvin Grove.

Bamser Involvement In The Project

Bamser provided specialist tunnel constructability services in three specific phases aligned with the chronology of the BCC’s RfP process. These included:

1. An initial ‘proactive’ phase aimed at reducing the cost of the project by clarifying or altering specific technical or physical requirements of the project for the information and action of bidders.

2. An ‘intermediate’ phase aimed at interpreting, quantifying and providing advice to BCC regarding alternate and innovative concepts expected to be proposed by the DCMO bidders.

3. An ‘evaluation’ phase where the three proposals are reviewed from a tunnel construction and programme perspective, and advice provided

The services included detailed consideration of some of the following, ultimately to ensure a more affordable project for the BCC;

• Tunnel concept designs including innovative solutions based on value engineering and technical assessment (cross section focus)
• Critical underground engineering design review for both tunnels and other underground structures (ventilation /smoke /electrical and sump structures)
• Technical specification development and review (lining and waterproofing focus)
• Identification, assessment, quantification and mitigation of tunnel project risks
• Tunnel options review and analysis
• Tunnel programming
• Tunnel logistics analysis
• Construction methods advice and options analysis
• Constructability analysis and advice including project staging options
• Construction site setup, layout and resourcing
• Tunnel construction plant reviews and recommendations
