Istram, developed by Buhodra Ingeniería S.A., is a civil engineering design and BIM platform focused on linear infrastructure. It streamlines the planning, design, and delivery of roads, highways, railways, tunnels, and urban corridors by integrating terrain modeling, geometric design, and 3D corridor modeling in a single environment.
Key capabilities:
- Alignment design: Robust horizontal and vertical alignment tools with superelevation, transitions, and rail geometry.
- Corridor and cross-sections: Template-based cross-section definition, automatic cross-section generation, and parametric corridor modeling.
- Terrain and survey: Digital terrain modeling from survey data and point clouds, with tools for grading and surface editing.
- Intersections and roundabouts: Dedicated tools to design, analyze, and optimize complex junctions.
- Earthworks and quantities: Volume calculations, mass-haul analysis, and quantity takeoff to support estimating and construction planning.
- Documentation: Automated production of plans, profiles, cross-sections, and reports tailored to project standards.
- Interoperability: Imports and exports common CAD/BIM and survey formats (such as DWG/DXF, DGN, LandXML, IFC, and point clouds) to support OpenBIM workflows and coordination.
- Construction deliverables: Creation of 3D surfaces and models suitable for machine guidance and field staking.
- Standards and customization: Libraries, templates, and rule-based settings to align with regional design standards and automate repetitive tasks.
Istram helps engineering teams improve accuracy, reduce rework, and accelerate project delivery by connecting survey, design, and construction workflows in a flexible, standards-aware platform. It is used across the project lifecycle, from feasibility and preliminary design through detailed design and construction.
