Northern Pipeline Interconnector (NPI) - Stage 2

The proposed NPI - Stage 2 will be approximately 48km and extend from NPI Stage 1 Landers Shute water treatment plant at Eudlo to the Noosa water treatment plant near Cooroy on the Sunshine Coast.

NPI - Stage 2 is a critical link in the bulk fresh water delivery infrastructure needed to secure the region's water supply.

The Project has 15 individual trenchless or tunnelling methods adopted to traverse the pipeline under rail, roads, creeks, rivers and rocky outcrops. The tunnelling scope encompasses over 2.5 Km of varying diameters and methodologies to house the water pipeline. The tunnelling scope includes a challenging 1050m, 2.1m ID (Internal Diameter) microtunnel without provision of intermediate shafts.

Bamser Involvement In The Project

Bamser were introduced to the Project to aid the Alliance in all areas relating to the trenchless methodology contemplated. Specifically, Bamser have provided the following support both in a short term and long term capacity:

• Provision of the Tunnel Manager on a long term basis (Project planning and delivery);
• Specialist off site estimation work used in the development of the TOC (short term);
• Provision of Senior Project Engineers working on the tunnelling scope (short and long term).

Bamser’s engagement has been initiated to manage all the tunnelling portions of the Project, namely:

• Project Management;
• Design Management;
• Estimation Services;
• Optioneering of Project Solutions;
• Programming and Cost Management
