Wulkuraka Maintenance Centre wins national award


The $4.4 billion New Generation Rollingstock (NGR) project has won a national award for the design and construction of the project’s Maintenance Centre at Wulkuraka.

The project won the Smart Infrastructure Award at the IPA National Infrastructure Awards ceremony in Sydney overnight.

The Queensland Government project is being delivered under an Availability Public Private Partnership (PPP) with Qtectic.

The NGR project team implemented state-of-the-art Building Information Modelling (BIM) software for the design and construction of the Maintenance Centre, which was completed six weeks ahead of schedule.

BIM software provides a single 3D design model used by both design and construction teams. It provides a seamless bridge between the teams, delivering more coordinated and reliable output.

Laing O’Rourke, who led the design and construction of the Maintenance Centre, should be congratulated for their use of BIM on the project. This was the first time that BIM had been used on a project this large in TMR.

There was significant potential for design clashes and programming conflicts on a project of this scope. There were often more than 200 construction staff on-site during construction – with more than 50 separate contractors and subcontractors engaged during the 18 month construction period.

Taking this potential complexity into consideration, the design and construction teams decided that BIM would be the best system to make sure they got it right the first time.

Right from the initial scoping and planning stages, all of the design and construction team updates were regularly consolidated into a single BIM model where all changes were easily identified, tracked and managed – providing opportunities for improvement to the design.

The single design model facilitated the integration of engineering elements – Mechanical, Electrical and Plumbing – with civil and structural elements. This resulted in the identification of over 3,000 clashes between the structure, underground drainage and in ground services during the design phase. The identification of these clashes considerably reduced delays to construction from potential design-related issues.

A genuine construction management benefit was also realised through use of GIS Data embedded within the BIM model for 3D earth moving machine guidance.

By using BIM, the Maintenance Centre was able to be simulated through a range of different techniques, including fly-throughs, walk-throughs and activity sequencing. Safety procedures were developed by using the building model to simulate the implementation of the processes concerned and effectively creating a digital method statement for specific processes.

The benefits derived from BIM have been tangible on the design and construction of the NGR Maintenance Centre, and contributed to the successful and early delivery of the project.

My congratulations go to the NGR team for winning this prestigious award.
