BIM software for the design of roads and highways

BIM software for the design of roads and highways

SierraSoft Roads is a BIM software for the design of roads and highways

The BIM functions of SierraSoft Roads allow you to produce, modify, share, and analyze road information models.
Design and information modeling occur simultaneously with a strong optimization of activities and cost containment.
In one product you have all the tools for design, policy control, information modeling and quantities calculation.

The parametric dynamic design in BIM

Projects in BIM with an ease that is incredible

Design and BIM

The design activities, geometric-informative modeling and the definition of the interoperable model take place simultaneously and in a single work environment.
Insert the axes, define the typical sections, set the characteristics of the BIM model and with one click you have the finished project, the drawings and the information models.
BIM increases the value of your design.

Parametric modeling of infrastructure corridors

Axes, profiles, and typical sections automatically generate dynamic 3D infrastructure models.
Every design change updates geometries, drawings, quantity takeoffs, and the BIM model in real time.

Modification and check in real time

It is possible to control the design like never before, drastically reduce designing time thanks to 3D real time cross-section on planimetry.
By changing a parameter everything is updated automatically.
The result can be immediately checked even before creating the final project.
Maximum control over the entire design and over every detail.

M3 Framework Database
All data relating to design and information modeling (geometries and data) are stored in the M3 Framework Database managed by SierraSoft Roads.
The M3 Framework Database stores all the parameters and data of the project, of the information modeling (geometries and data) and of the information exchange.
SierraSoft Roads generates, starting from the data contained in the M3 Framework Database, all the necessary information documents and information models, with content and level of detail based on the requests.
The M3 Framework Database is the only reference for information and guarantees consistency between project data (plans, profiles, sections), information documents and information models.

Widenings and superelevations are automatically calculated during the geometry annotation.
Everything is displayed in real time, calculated and verified according to the set legislation.
The drawing of the geometry annotation plan is complete with all the dimensions of the various elements that make up the alignment.
The drawing is customizable thanks to the numerous dimensioning options available.

Longitudinal profile

The terrain profile is automatically returned based on your settings.
You can get profiles from different sources: 3D models, axes, sections, polylines, etc.
You can extract and analyze edges, walls, ditches and any other element of the section, directly on profile.
The project profile is defined with grade lines, circular curves, parabolic curves.
The graphic representation of the profile in the desired scales is complete with all the design elements.
Profile dimensioning is fully automated and customizable.

Road intersections

Design any intersection with ease and precision

Make any kind of road intersection with unprecedented speed and precision.

Create and modify intersections while maintaining control of the results, whether it be roundabouts, at-grade intersections or complex interchanges.

Typical sections and typical objects

Parametric and programmable for maximum efficiency and flexibility

Create and manage the typical section within a specific environment by assembling parametric objects included in the software or defined by the user.
Standard objects include roadways, courses, ditches, channels, walls, generic objects.
The creation of the typical objects takes place in a dedicated environment.
You can parameterize features and data, and if that's not enough, you can program them using the included scripting language.

Cross sections

Automatic and always consistent with the information model

Extract all data wherever they are: from triangle models, from point clouds, from other axes, from information models (railways, roads, hydraulic works, bridges, tunnels, ancillary works, buildings), from cartography.
The insertion and management of the project typical section takes place completely automatically on the basis of the data settings of the parametric design.
The drawing of the sections, completely customizable, includes the tables of quantities, the dimensions, the annotations box and the fills.

Quantities calculation

You decide what to calculate and how to calculate it

Extraction and calculation of quantities from different sources: sections, objects, surfaces, BIM entities, etc.

Definition of the quantities to be calculated (cut, fill, topsoil, etc.) based on the processes entered.
The results are stored within the information model and made available as printouts.

Policy

Free to design where you prefer

Calculations, checks and policies checks: SierraSoft Roads checks if your project complies with the policy.
Check the congruence of the design parameters of the axes with the selected policy.
Generate and test the visibility diagram and the speed diagram.
Generate the speed diagram.

Get, starting from a point, the path of the water or the contour line.
Displays slope vectors, valleys, ridges, tributaries, flat areas, maximum and minimum points on the terrain or project surface.
Calculate the filling volume of a basin.

Advanced information modeling

Define your BIM model in detail

The information modeling takes place simultaneously with the design based on specific customizable settings.

The structure of the model, the elements that compose it, the geometric representation of the objects and their information content are defined.

The integration of buildingSMART's IDS (Information Delivery Specifications) and bSDD (buildingSMART Data Dictionary) standards directly into parametric information modeling enables easy and intuitive creation, management, modification, and validation of information content, ensuring data consistency between project, information model, and information requirements.

Thus you create an information model according to the specifications required in the BIM Execution Plan (BEP).
The information model is created while maintaining information consistency with all the information documents created.

The activity of multidisciplinary collaboration is supported by the implementation of the BCF (BIM Collaboration Format) standard, facilitating both design integration and BIM collaboration.

Requires the SierraSoft BIM Modeling software extension.

Information analysis and verification

Analyze and verify the information content of BIM models

The analysis, verification and validation of information content occur simultaneously with the activities of design and information modeling. This aims to identify and resolve any design and modeling errors at the point of origin, where it costs least to resolve them.
Then so identify interferences between created models and between federated models, verify the structure, the elements and the information content. In addition to standard checks, specific checks are provided for topographic and infrastructural information models.
Requires the SierraSoft BIM Checking software extension.
