civil design



All-in-one road, piping and site design solution.

Developed and supported in Australia for over 20 years, Civil Site Design empowers civil designers to work smarter and faster.

Integrated with your CAD platform of choice — Civil 3D, AutoCAD or BricsCAD — Civil Site Design provides you with a design and drafting solution in the one environment.

Plus, it’s surprisingly affordable!

Automated Road Network Design

Design in hours, not weeks

Civil Site Design has tools to automate road networks, intersections, cul-de-sacs and roundabouts. Our world-first Artificial Intelligence-enabled “Project Assist” can even automatically create an entire subdivision project, ready for you to simply fine-tune the design.

Stormwater & Drainage

With DRAINS data exchange

Civil Site Design enables the rapid creation of underground stormwater drainage systems, with interference checking to avoid conflicts with underground services. Based on the Rational Method, Civil Site Design has data exchange with Watercom DRAINS and PC DRAINS.

Real-time 3D Visualisation

Immediately identify and rectify errors

When editing projects, 3D visualisations are automatically rendered in real-time to assist your design and allow you to identify and resolve errors immediately. These visualisations can be sent to clients and stakeholders to assist the understanding of project outcomes.

Genium Civil Engineering uses Civil Site Design on the BricsCAD platform for design of civil infrastructure and find the combination of this software a great fit for our business. The continual development of the software by Civil Survey Solutions means we have state-of-the-art tools at our disposal to be able to improve design efficiency and the quality of our design outputs. I highly recommend Civil Site Design running on BricsCAD to anyone wanting a high quality, cost-effective and intuitive civil design package.

Simon CassidyDirector Civil Engineer, Genium Civil Engineering

I have been using AutoCAD Civil 3D with Civil Site Design since 2004 for road, dam and pipes design. Civil Site Design increases productivity and speeds up project delivery... [and] is fully compatible with AutoCAD Civil 3D. With its quick and easy user interface and functionality, Civil Site Design is my design program of choice.

Bede MulhollandSenior Designer Civil Infrastructure, WSP

I have been using Civil Site Design in AutoCAD Civil 3D since 2007... [and] find it very intuitive and much simpler to use in most projects than C3D corridor modelling. The advances in the user interface, the help system, the YouTube Channel, the ease with which we can select and trim out elements to build selective models, the simplicity of Model Viewer and auto curb returns all allow me to achieve great results very efficiently. Now, we can export any Civil Site Design road model to a corridor model and update both ways, so we get the best of both worlds!

Peter ThomsonSenior Civil Designer, MWH

[Civil Site Design's] integration... directly within AutoCAD has led to a significant improvement in our overall efficiency in terms of the Civil Design aspects of our work... [it] is a much more flexible and dynamic software package which allows us to see the impacts that certain design changes have on other elements in real time.... We are now also able to undertake... [Drainage Design] much more efficiently specifically due to the ability to see existing underground assets while designing the new drainage infrastructure.

Chris EvripidouDirector, CRE Consulting Engineers Pty Ltd

[We have used] Civil Site Design (on AutoCAD) for Subdivision Design since 2013. It is an intuitive and flexible design package that adds value to our business. Initially it was used for Road Design and has grown to be integral in all our civil design including Stormwater, Sewer, Retaining, Onsite Detention and Dams. Technical support are prompt and very thorough in resolving issues. Customer feedback drives many features and enhancements in updates. Of particular benefit to us is the interconnection with Watercom Drains saving hours of work on Stormwater modelling. I always look forward to the productivity improvements each update brings.

Turbocharge your workflow with innovative, powerful yet simple-to-use civil design tools.

Civil Site Design has been developed to provide road design and outputs directly inside your choice of CAD – AutoCAD, Civil 3D or BricsCAD.

Our philosophy of combining template and string-based design, as well as automating common design elements such as intersections and roundabouts, provides a familiar and complete set of tools for rapid creation and output of your road subdivision, reconstruction, rural, highway and other design projects.

Built for rapid design of features such as building pads and detention basins, the dynamic grading tools automatically clean up internal overlapping corners and include radial and mitre options on external corners.

With the Site Grading tools, you can take a polyline and apply a cross-section template (assembly) to create a graded surface, complete with corner clean-up. The surface and grading linework automatically updates as you edit your grading, so you get immediate feedback on the impact of your design changes as you make them.

Civil Site Design Pipes includes all the tools you need to quickly create your pipe networks and avoid crossing services and other pipe networks.

Working inside the drawing environment, you can create and design Stormwater Drainage Networks, Sewer Networks and undertake general pipe design.

Service obstruction checks are included in the design process for you to quickly optimise your designs and avoid conflicts between underground services.

Every day, more businesses

make the switch to Civil Site Design.


Here’s why.

Integrate design & drafting in one environment.

No need to exchange data like 12d® Model and CAD. Avoid the notorious QA problems of 12d® Model and CAD files not synchronised. Output long section/cross sections & reports directly from your design environment.

Reduce civil design software costs – significantly.

Choose between perpetual or subscription licensing, available in both standalone (single user) or network (multi-user) licences. Civil Site Design’s software and ongoing maintenance costs are markedly more affordable than similar products like 12d® Model.

It’s fast and easy to learn. Yes, really.

Get new users commercially productive with Civil Site Design in a matter of weeks. Can you afford the years that it takes to train a 12d® Model operator? With our modern interface, logical workflows and huge range of training and resources, you can get going fast.
