Deliver sustainable, high-performance buildings

OpenBuildings Designer is a multidiscipline Building Information Modeling (BIM) software that streamlines the work among architects and electrical, mechanical, and structural engineers. You can design, model, analyze, manage, and construct buildings of any size, form, and complexity with information-rich models. Using a federated data approach to modeling and drawing management will allow you and your team members to work on any size models simultaneously, regardless of stakeholder location. With OpenBuildings Designer, you can design, model, and analyze multidiscipline rail stations, as well as perform pedestrian simulation.

Take advantage of building information modeling (BIM)

OpenBuildings Designer provides BIM advancements, so you can deliver buildings faster and with greater confidence. BIM is a fully immersive 3D modeling environment that integrates information for multiple disciplines, companies and project phases. Leverage BIM methodologies to improve your project delivery and better manage your design information across the entire project lifecycle. With BIM analysis, you get a better understanding of the data rich digital representation of your building to improve the odds of delivering a building on time and on budget. You can explore design options, conduct analysis and better communicate design intent.

Increase collaboration among disciplines

Work together more efficiently in a project environment with a shared library of design components, tools, workflows, and production standards. Integrate information from multiple formats and share models and drawings across geographically dispersed teams without sacrificing discipline or responsibility. And keep stakeholders in the loop with renderings and movies using built-in visualization tools to make it easier for you to evaluate materials and communicate designs in ways that bring ideas to life.

Efficiently explore design alternatives and address real-life design scenarios

Model any type of building or infrastructure—including commercial, industrial, transportation, education, and government buildings, as well as structures such as bridges and tunnels. Built-in clash detection makes coordinating building systems more efficient. Using computational design, evaluate more approaches and options for designs faster, while improving overall quality. Embedding design intent with expressions and constraint-driven geometry minimizes repetitive modeling work, while integrated energy services provide the ability to predict the performance impact of changes.

Design and simulate transit stations

Do it all from high-speed and commuter to metro and light rail—as well as pedestrian travel paths. The work set of functional space definitions and catalog of design components are specifically geared to railway station design.

GenerativeComponents templates for complex geometry, for example, are ideal for designing tunnels and platforms. Create simulation scenarios by defining spaces, activities, passenger characteristics, and operational information such as train timetables to simulate and analyze foot traffic.
