BIM Ready Solutiona for Roadway Design and Reconstruction

Plateia from CGS Labs, Slovenia is a professional, BIM-ready, 3D road design and reconstruction software solution. It provides the commands and tools to support the entire design process, from preliminary to detailed design, from the initial input of survey data to complex 3D road models with analysis tools, to documentation and publishing features.

Using its flexible, dynamic data model, Plateia supports BIM (Building Information Modeling) workflows and processes. Carefully designed UI and workflows are consistent with the road design engineering practice. This makes Plateia fast-to-learn and easy-to-use.

Plateia is a Greek word meaning town square. It is symbolically the point of reference in traveling and guiding. In terms of its product positioning, Plateia is a replacement for Civil 3D and similar 3D Surveying and Civil software and provides a cost-effective alternative.

Product Details

Digital Terrain Modeling

The Surface creation tool is included in CGS Labs software to produce detailed Digital Terrain Model (DTM) based on various surveys or other input data: total station data files, points, break lines, blocks, etc. This offers the possibility to use Plateia on plain AutoCAD or BricsCAD.


Creation of complex slopes with multiple conditions in cut or fill gives users the capability to cover various design scenarios and geometry requirements for all kind of road projects, from simple forest road design to complex intersection geometry design. Furthermore, creating ponds, parking areas, platforms, road, rail tracks, river channels, and other features is easier and faster with CGS Labs grading functionality.

Roadway Geometry Design Tools

Plateia provides a wide range of advanced alignment, profile geometry design, and editing tools. They include P(V)I design, floating and fixed elements design, alignment design created from the existing polyline, or ultimately creating a best-fit alignment based on existing road centerline or road edge survey data. Superelevation calculation is a comprehensive definition and editing tool. Plateia supports several superelevations definitions and pivot point options according to various European and AASHTO roadway design standards. A number of alignment labels according to different country standards, reports, and data export options give you the flexibility to cover a wide range of user requirements.

Intersections and Roundabouts

Automated intersection and roundabout design is based on road geometry defined by alignment, profile, and super-elevations. The 3D Intersections function automatically adjusts secondary road profile and super elevation parameters with corresponding user defined curb returns. Automated intersection design results in detailed 3D intersection geometry for X or T shaped intersection types. Use the grading/surface mode with various parameters to customize 3D intersection geometry, and then use the automatic update option when alignment geometry changes.

3D Surface and 3D Solid Model

Roadway 3D model can be created as 3D surface or 3D solid model. 3D roadway surface model can be generated automatically from 3D road edges and terrain model, or it can be built with the grading function. 3D solid model is created on the basis of cross-section areas, where materials and volumes can be defined as extended data. With 3D solids we can also build tunnels, bridges and similar objects. Solid objects can be aligned with arcs and transition curves. All solid models, including extended data, can be imported into Autodesk Infraworks, Navisworks and can be used in various BIM workflows.

Cross Section Design and Editing Capabilities

Plateia provides capabilities for designing and editing roadway cross sections in a detailed way with almost no geometry limitations to the final project design. Adding multiple roadways to a single cross section gives you control over the geometry between the roads and other infrastructure objects your project requires, and lets you define these areas with great accuracy and detail.

Quantity take-off (QTO)

Plateia calculates material quantity take-off and features a QTO data export tool with custom defined Pay Item (Bill of materials) options. It gives users the possibility to link material defined in the drawing with a material database in cost estimate software, thus supporting digital data transfer and fast cost recalculation when project changes arise.

Mass Haul Diagram

Mass haul diagram presents a graphical view of the material moved in the proposed design site. Mass haul diagrams help designers and contractors understand where gross material movements occur and compare the economies of alternative designs. These diagrams are presented along with profile views for the design review phase.

Road Reconstruction/Rehabilitation

The road reconstruction/rehabilitation function offers powerful regression analysis tools for best-fit alignment and profile creation based on existing road centerline or road edge surveyed data. This gives you a detailed profile view for the existing and new roadway elevation, together with a calculation of resurfacing material quantities.

Autosign: 3D Traffic Signs, Road Markings, and Road Sign Gantry

Autosign is included in Plateia Ultimate and Plateia Professional software suites. It provides users with everything necessary to design, edit and visualize 3D traffic signs, road markings and road sign gantries. Several country-specific traffic signs libraries are available as well as traffic signs and road markings reports with quantity data.

Visibility and Stop Sight Distance

The Visibility and Stop sight distance road geometry tool gives you the graphical visibility distance analysis required to safely stop a vehicle traveling at design speed. This facilitates planning to avoid collisions with any other immobile objects obstructing the travel path. It supports various country specific guidelines and a number of calculation input parameters.

Autopath – Swept Path Analysis

Autopath, CGS Labs swept path analysis software is included in Plateia Ultimate software suite. Autopath meets all your professional horizontal and vertical vehicle swept path analysis needs. A range of driving methods combined with predictive turning technology and dynamic editing capabilities are available. Additionally you get several vehicle clearance analysis and animation tools. Autopath comes with predefined country-specific libraries of vehicle types, offers customization tools and supports special multi wheel transportation vehicles.

Dynamic Data Model

Plateia stores all design data inside a .dwg data file, making for quick geometry updates and data exchanges within CGS Labs software solutions, and Autodesk software. LandXML, OKSTRA, REB and AutoCAD Civil 3D data exchange interfaces are available. Dynamic updates to all geometry changes or design parameters are supported within single or multiple drawings with separated layout/profile and cross sections data.

Supporting Large Projects

Plateia easily handles large projects with very long alignments and thousands of cross-sections within seconds. Projects are neither limited in size nor is the performance critically affected while working on large scale projects, including extra long and multiple alignments, profiles, and cross section views. Cross sections can provide a high level of details with on-demand synchronization options, great processing speed, and consistent data.

Collaboration Capabilities

Large roadway projects can be efficiently divided among multiple team members, who can then work simultaneously. Projects can be done in a single drawing or split into several drawings, separating layout, profile, and cross sections.

Plateia is available in several languages and supports country specific road design standards, drawing layouts, traffic signs and other symbols, vehicles, etc. Customers are entitled to use any country specific version of the software in case of designing projects for the foreign countries. Currently supported country/language versions are:

  • English (Int. and USA-AASHTO)
  • Austria
  • Bulgaria
  • Croatia
  • Czech Republic
  • Germany
  • Hungary
  • Macedonia
  • Poland

Extend Plateia’s functionality with point cloud data processing software – 3Dsurvey

3Dsurvey is a standalone software solution for point cloud data processing. Use any UAV with Lidar, a digital camera, DSLR, or a GoPro to capture images and process them in 3Dsurvey.

Create orthophoto data or digital terrain models, calculate volumes, profiles, and even more. Export digital terrain models to Plateia to create road projects based on detailed surface model, calculate material volumes, and export 3D road surface models from Plateia back to 3Dsurvey to create stunning aerial or drive-through visualizations.
