Engineering Software for Commercial, Industrial, and Residential Sites
OpenSite+ is the first-to-market AI-powered civil engineering application specifically created for site design and land development projects. Design with the familiarity of 2D in a 3D modeling environment. Featuring smart site objects, optimization tools, generative design, and artificial intelligence, you can reduce repetitive tasks, focus on evaluating design alternatives, and deliver projects 10 times faster without sacrificing quality. Deliver Projects 10X Faster with Greater Accuracy One-stop Solution Spend less and reduce your tech stack. Hit project delivery deadlines on budget with an all-in-one software for site layout, drainage design, documentation, and more. AI-powered Productivity Automate time-consuming and error-prone tasks, such as annotations, plan production, and grading optimization. Address Workforce Challenges Work with a user-friendly and innovative UX that simplifies onboarding, attracts top talent, and improves retention.
10X Faster Construction Drawings
Cut production time, reduce errors, and ensure consistency across all project documentation with AI-assisted drawing production. Benefit from:
- Automated annotations, labeling, and sheeting
- Dynamic change management for instant updates
- Customizable standards and client requirements enforcement
Reduce Time Spent on Manual Data Retrieval and Analysis
Use natural language or voice-activated commands to ask questions and execute tasks (parking count, building square footage, confirm zoning), receiving evidence-based answers from your existing site designs and project documentation. Benefit from:
- Instant suggestions to complex problems
- Real-time design optimization
- Client requirement and compliance checks
- Voice-activated design creation and modification
Instantly Access and Integrate Contextual Data
Consolidate diverse data formats into a project-ready foundation to quickly start projects with accuracy. Integrate contextual information from multiple high-quality sources, including:
- World Terrain (Cesium tiles)
- USGS terrain data
- Integrated image streaming services
- GIS (ESRI) platforms
- File-based terrain (GeoTIFF, LandXML)
- CAD files (DGN, DWG)
Optimal Construction Costs in Minutes
Minimize delays and cost overruns caused by unforeseen site conditions with data-driven decision-making. Enhance your estimating process with:
- Thousands of design scenarios evaluated with a click of a button
- Precise cut/fill analysis for best-value construction
- Real-time cost updates with design changes
- Dynamic grading adjustments for parking lots, roads, buildings and more
Integrated Drainage Design and Analysis
Simplify stormwater design with native OpenFlows design and analysis capabilities. Benefit from:
- Seamless design-analyze-optimize workflows
- Accuracy in drainage calculations
- Reduced risk of data loss
- A time-saving unified platform
