OpenSite

An innovative, all-in-one application for rapid site modeling and earthwork optimization that accelerates project feasibility and detailed design.

What is OpenSite?

OpenSite Designer, provided by Hertford Systems, is a comprehensive site design application that handles everything from initial concept to final construction documentation. Unlike traditional CAD tools, it uses an “open modeling” environment to integrate reality meshes, geotechnical data, and underground utilities into a single intelligent 3D model. By utilizing parametric modeling and a powerful grading solver, it allows engineers to evaluate design intent in the early stages of a project, ensuring optimal design delivery for commercial, residential, and industrial land development.

OpenSite Designer streamlines the entire site development workflow by combining traditional engineering with 3D parametric modeling. It enables rapid iteration of site layouts—including parking lots, building pads, and driveways—while automatically optimizing earthworks to find the most cost-effective construction solutions.

  • Earthwork Optimization — Run thousands of iterations with a grading solver to minimize cut-and-fill costs based on user-defined constraints.

  • Rapid Site Layout — Quickly conceptualize and detail building pads, parking lots, and sidewalks with dynamic, rule-based design tools.

  • Drainage & Utility Design — Model and analyze complete stormwater and sanitary sewer networks fully integrated with the site topography.

  • Geotechnical Integration — Incorporate boring data and subsurface terrains directly from gINT to identify project risks early.

  • Automated Deliverables — Generate consistent 2D plans, 3D models, and quantity take-offs directly from the live model to reduce manual drafting.
