OpenSite+
Bentley's generative AI application for civil site design that delivers projects up to 10 times faster by automatically generating compliant design alternatives from engineering constraints.
Definition
OpenSite+ is Bentley Systems' generative AI application for civil site design, currently in limited availability. The system accepts project constraints—topography, utility clearances, grade requirements, drainage standards, and environmental buffers—and automatically generates multiple compliant design alternatives, compressing the iterative design process from weeks of manual work to hours. Bentley announced OpenSite+ can deliver projects up to 10 times faster than conventional design workflows. Part of Bentley's broader AI investment strategy at Year in Infrastructure 2025, OpenSite+ targets civil engineers, land developers, and transportation agencies who need rapid feasibility studies, grading plan alternatives, or optimized site layouts for complex terrain. It connects to Bentley Infrastructure Cloud for data continuity across design, review, and construction phases.
Examples
Generating 12 grading alternatives for a mixed-use development in under an hour instead of two weeks
AI routing site access roads around protected wetland buffers while optimizing cut-fill balance
Producing a feasibility study site layout with utility connections, drainage, and parking in a single AI pass
