History Files: Gas Plant Civil Design – Kellogg, Brown and Root

In a gas plant project, 12d Model was used to design civil engineering components for integration into PDMS (Plant Design Management System), supporting multidisciplinary design coordination.

However, PDMS did not natively support certain civil engineering elements, including road designs and TIN surfaces. Transferring civil design data required additional CAD preparation and manual editing, making updates time-consuming and increasing the potential for errors.

To address this, a custom macro was developed to automate the transfer of civil engineering elements from 12d Model to PDMS. Using configurable mapping files, the workflow could be adapted for different PDMS projects, reducing manual intervention and streamlining design updates.

The resulting workflow enabled more efficient transfer of civil design surfaces, allowing other disciplines to access updated information for design coordination and clash checking. It also preserved the flexibility of 12d Model for civil design modifications while reducing reliance on manual CAD editing.

This project demonstrates how 12d Model’s customisation and automation capabilities can improve data exchange and support multidisciplinary coordination in complex plant design environments.

The Tipster: Processing Super Alignment Styles

Producing road and rail plans requires clear, well-organised annotation without compromising the visibility of other design information.

This video demonstrates the Super Alignment Style Output – Explode and Process Labels tool in 12d Model, which converts Super Alignment labels and symbols into individually named output models for more flexible plan presentation.

Key capabilities include:

  • Individual output models for each Super Alignment string.
  • Configurable label formatting, including trailing-zero trimming and start-of-alignment display options.
  • Flexible annotation placement to improve drawing clarity and minimise conflicts with other design elements.
  • Structured text and symbol naming to support downstream drafting and layer mapping in AutoCAD workflows.

For engineers and design teams preparing road and rail documentation, this provides greater control over annotation and the final presentation of design drawings.gineering

History Files: Port Hedland Rail

Calibre Rail, now part of WSP (https://www.wsp.com/en-au), played a key role in the Rowley Yard expansion for Fortescue Metals Group in Port Hedland, Western Australia, using 12d Model to tackle complex rail, earthworks and drainage challenges while supporting a cost-effective solution that saved more than AUD $2 million in capital costs.

Fortescue Metals Group (FMG) undertook a $US8.4bn expansion program to triple the size of its operations and take it to 155 million tonnes of iron ore per annum by mid 2013. FMG had a triplication of their rolling stock fleet. To meet the demand and the growth in associated maintenance procedures, an expansion of their existing facilities at Rowley Yard, Port Hedland was required.

FMG expansion plans ceased during the global financial crisis. As a result, the study and execution of their ambitious plans ground to a halt. Calibre Rail’s role as EPCM contractor was to take these preliminary studies and upgrade the mainline, which started in late 2010. With construction commencing on the other elements of the mainline (such as the triplication of the load-out loop, a new fuel facility and duplication of the mainline), there was little time to investigate the issues associated with Rowley Yard. A few of the issues faced include: – Earthworks modelling of both sub-grade and capping layer – Drainage issues and tying into the existing network – Service clashes – Development of a staged approach to the construction of the yard to minimise disruption.

20 options were investigated using the powerful ‘element method’ tools within 12d Model’s Super Alignment, with the turnout placement function providing a quick and effective method to arrange track layouts. Storm water drainage design was developed in 12d Model. Three options were investigated, limiting pipe sizes to 900, 1200 & 1500(mm). A cost/benefit analysis was completed that compared pit and pipe quantities and thrust boring sites. With the site 1600km away from the nearest pipe supplier, this decision was critical to logistics planning. “Using 12d to design this solution saved more than $AUD2million in capital costs for the project.” The storm water drainage design was independently verified. Diversion drains were mapped in 12d Model using the HEC RAS writer. Importing the water surfaces from HEC RAS to 12d Model was used to then calculate tail water conditions.

“12d modelling isn’t just a click of a button. It often takes many attempts to find a solution to a problem. In a brown field environment, where little planning had been done in the past…issues were constantly faced. “It seemed that everything we touched was broken and every solution we tried to implement failed. This led to blowouts in the delivery, but we are very happy with the result thanks to 12d Model and its vast array of tools.”

History Files: Olympic Village London 2012 – Arup

When the deadline is the Olympic Games, there is little room for redesign, delay or coordination issues.

When London was selected to host the 2012 Olympic Games, the city had to deliver large-scale venues and infrastructure capable of supporting approximately 24,000 athletes. The Olympic Village site presented an additional challenge: it was located within an already developed urban environment, constrained by surrounding infrastructure including a high-speed rail link, while also requiring new roads, earthworks and utilities to support the Games.

For Arup, the scale and complexity of the project called for a different approach to civil design. Stakeholder feedback meant that design options would continue to evolve, while contractors were already working to demanding construction programmes. Changes therefore needed to be assessed quickly and translated into construction documentation without disrupting the wider design.

Arup implemented 12d Model to bring the civil design together in a single, connected model. Earthworks, roads and utilities were modelled within 12d Model, allowing designers working on different elements to reference shared design information and coordinate their work.

This was particularly valuable for the site’s extensive subsurface utilities. By modelling the utilities alongside the other civil elements, the team could identify potential clashes during design rather than discovering them during construction. As the design developed, 12d Model’s automated recalculation capabilities also allowed options and changes to be tested quickly, making it easier to assess their impact across the wider site.

The complete 3D model provided another important advantage. Arup and the client could review the civil design from all angles before documentation and construction, helping them assess how roads, earthworks and underground services would work together within the constrained site.

Once the design was confirmed, the model could be used to produce the documentation required by construction contractors. Automated processes and reusable standard components helped reduce manual work and accelerate the design cycle, supporting the project’s demanding programme.

The result was a more connected design process that allowed Arup to develop, coordinate, review and document the civil works within a single model, helping keep pace with one of the world’s most time-critical infrastructure projects.

As the project team noted:

“The modelling of all subsurface utilities in 12d Model was the ultimate design solution to prevent problems during the construction phase.”

The London 2012 Olympic Village is a strong example of how integrated civil modelling can help engineering teams manage complex sites, respond to changing requirements and make critical design decisions before they reach construction.

The Tipster: Getting Started with Super Alignments

Super alignments are a powerful string type in 12d Model that allows horizontal and vertical geometry to be managed independently within a single string. Unlike a standard super string, a super alignment can contain its own horizontal geometry—such as straights, curves and transitions—and vertical geometry, including grades and vertical curves. This makes super alignments particularly useful for design applications where both the plan and profile need to be controlled independently while remaining linked through chainage. In 12d Model, super alignments are commonly used for road and rail design, airport runways and taxiways, drainage channels, and other civil infrastructure projects.

One method for creating a super alignment is the IP (Intersection Point) method, which builds the horizontal alignment by establishing horizontal intersection points (IPs). The initial straights are defined through the IPs, after which curve radii and, where required, transitions or spirals can be added. The vertical component can then be developed separately using vertical intersection points (VIPs), grades and vertical curves. This approach gives designers greater flexibility when refining an alignment, including the ability to insert specific grades over a set distance, change existing grades, add vertical curves, or position IPs precisely using coordinates and CAD snaps.

Creating a super alignment in 12d Model starts from Strings > Super Alignment > Create a Super Alignment, where users can define properties such as the string name, model, colour, starting chainage, labelling style and whether the alignment should be closed. Advanced settings also allow a super alignment to be configured as a pipe or culvert, with options for its justification and size. During editing, dedicated super alignment tools can be used to add or move IPs, insert curves, extend geometry, adjust grades and refine the horizontal and vertical design. These specialised tools are important because super alignments are a unique string type and have their own editing functions.

Existing strings can also be converted into super alignments, making the workflow useful when working with survey or CAD data. Individual strings can be converted through Strings > Convert > Super Alignment, while multiple strings can be processed through Utilities > A to G > Convert > Super Alignments. When bringing CAD geometry into 12d Model, separate lines and arcs can first be joined into a single string using the Head to Tail utility before conversion. The conversion can then be performed using either the IP or Element method. Once converted, the dedicated super alignment tools can be used to apply labelling styles and further edit the alignment, providing a practical workflow for turning existing design geometry into a fully editable horizontal and vertical alignment in 12d Model.

History Files: Bunbury Trotting Complex Upgrade – Thompson McRobert Edgeloe (TME) – now WSP

What began as a $1.36 million redevelopment became one of Australia’s most impressive harness racing facilities.

Led by Thompson McRobert Edgeloe (TME), the Bunbury Trotting Complex in Western Australia was completely reimagined—from replacing the existing 800-metre track with a new 960-metre world-class circuit to modernising the entire precinct with new stables, public viewing areas, broadcast facilities, and upgraded lighting.

Designing a track capable of delivering fast, fair racing while reducing stress on horses required extensive research and precise engineering. Every aspect of the geometry—from spiral curves to transitions—was carefully optimised to create one of the fastest harness racing tracks in Australia.

Using 12d Model, the entire project was digitally modelled, allowing the team to refine complex geometry with confidence and provide contractors with highly accurate construction data to achieve an impressive 5 mm surface tolerance. The same model was also exported into 3D visualisation software, enabling realistic renders and animations that helped communicate the final vision before construction.

The success of the Bunbury redevelopment quickly led to further opportunities, with TME commissioned to design additional harness racing facilities across Western Australia and Victoria.

Perhaps the project’s greatest endorsement came from those who raced on it. As leading Bunbury trainer Andrew DeCampo simply put it:

“It’s brilliant, mate, absolutely brilliant!”
