How the Ipswich Motorway Upgrade (Rocklea to Darra – Stage 1) team delivered pilot BIM at scale under pressure

The Challenge

The Ipswich Motorway Upgrade (Rocklea to Darra – Stage 1) involved road and ramp upgrades, additional lanes, cycleway provisions, flood resilience works and 10 new bridges, all within an extremely constrained corridor carrying over 80,000 vehicles per day. On top of that, the project was selected as TMR’s pilot BIM project, which meant the DJV was not only designing the job, but also helping set the benchmark for how BIM could be delivered on future Queensland infrastructure projects.

That created several overlapping challenges: managing BIM across multiple design platforms, maintaining strict quality document control on a government-funded project, creating a flexible working model across a joint venture and ensuring design and review efficiency under tight time and budget constraints. The project also had to satisfy TMR requirements including TeamBinder and a rigorous Scope of Works and Technical Criteria.

The Solutions

12d Synergy was implemented as the project’s centralized data environment, supporting BIM management, document control and worksharing across the BG&E and Cardno Design Joint Venture. Working alongside 12d Model for the majority of civil elements, and alongside Revit, Tekla and Navisworks for other parts of the design and federated BIM review, the platform gave the team a single controlled environment for managing files, workflows and design information.

To meet strict quality requirements, 12d Synergy enforced folder structures and naming rules, while check-in/check-out created a full revision history and stronger accountability. The system also supported a stand-alone server environment, isolated from the joint venture partners’ internal systems, allowing secure access for staff, consultants and subcontractors without exposing sensitive files.

The team also used 12d Synergy to eliminate paper-based design review. Instead of relying on printers, scanners and manual mark-ups, the DJV managed drawings and revisions digitally, with all mark ups visible in the document history and a more streamlined sign-off process for final review.

The Result

• Supported delivery of a $400 million transport infrastructure project.
• Helped manage Queensland’s first fully integrated TMR BIM pilot project.
• Enabled collaboration for 80+ staff at peak access across the project data environment.
• Supported a major design scope including 10 new bridges.
• Enabled remote work and national talent access, including a BIM Coordinator located 750 km away in Newcastle.
• Replaced paper-based review with a federated digital review process across hundreds of drawings and 20,000–30,000 mark ups.
• Improved document control with enforced folder structures, naming rules, revision history and airtight transmittals.

A BIM pilot demanded more than design capability

What makes the Ipswich Motorway Upgrade (Rocklea to Darra – Stage 1) distinctive is that the challenge was not only technical design. The project also had to prove a new way of delivering BIM in a live transport environment with government oversight, multiple software platforms and a joint venture structure. That meant success depended just as much on information control and collaboration as it did on engineering execution.

Spotlight: Ipswich Motorway Upgrade (Rocklea to Darra – Stage 1)

Rocklea to Darra formed part of the broader Ipswich Motorway Upgrade program in western Brisbane. Infrastructure Australia describes the Rocklea to Darra proposal as a 7 km section addressing congestion, freight efficiency, flood immunity, ramp rationalisation, interchange upgrades and wider corridor improvements, and notes that the Stage 1 widening from Rocklea to Darra has been completed.

That broader context helps explain why this stage carried so much weight. It was not just a single design package, but part of a strategically important corridor upgrade that also served as a pilot for future BIM-enabled transport delivery.  

Flexible working made joint venture delivery more practical

A standout part of this story is how strongly flexible working is tied to delivery performance. Stuart Cook wanted the project to support flexibility but doing that inside a design joint venture with separate organizations, consultants, subcontractors and firewall restrictions was far from simple.

By using a stand-alone, securely isolated server with remote access to the project CDE, the DJV created a controlled environment where people could work from home, the office or elsewhere without losing access to current files. This also meant the team could engage the best available specialists regardless of location, including a BIM Coordinator based 750 km south in Newcastle.

Quality control had to hold up under government scrutiny

As a government-funded pilot project, the Ipswich Motorway Upgrade (Rocklea to Darra – Stage 1) came with strict QA expectations. With more than 80 staff needing access to data at the peak of the project, maintaining standards manually would have been difficult and risky. 12d Synergy helped reduce that risk by enforcing folder structures and naming rules, and by giving the team a complete revision history through check-in/check-out.

That made final review far more efficient. Stuart Cook described sign-off as a “click and flick” process because he knew the relevant document control stages had already been completed and the history was visible.

A paperless review model improved efficiency under pressure

The project also used 12d Synergy to support a fully digital review process. With tight deadlines and budget pressure, Stuart Cook deliberately removed paper from design review: no printers, scanners, paper or pens. Instead, drawings and their previous revisions were housed together in a federated system, with mark ups captured in history and visible at final review.

That was not a small gain. Stuart noted that the team retained a couple hundred drawings for QA purposes and that the mark-ups were in the range of 20,000 to 30,000. A digital review workflow made that volume much more manageable and significantly reduced the material and productivity costs associated with paper-based processes.
