Bring in survey points, inspect your source data and establish the terrain beneath your design.
SURVEY & TERRAINTHE INDEPENDENT CIVIL ENGINEERING WORKBENCH
Turn site data into design intent. A focused Windows workbench for survey, terrain, roads and grading—with your project files right where they belong. On your machine.
Free evaluation · No card required · Runtime included
PRECISION IS THE CRAFT.
App capture · illustrative demo scene · development preview
Take a look inside before you download. Switch between five app captures below. Scenes are illustrative; live project tools and their release scope are documented separately.

Read the landscape through shaded terrain, contours and a focused surface inspector.
Demo scene · no real project dataSurvey, terrain and design tools connected by a common project foundation.
Work in a native Windows app. Keep project files on your machine and work offline.
A foundation for saved design intent, source dependencies and repeatable results.
A workbench being built around the way civil projects move from information to decisions.
Bring in survey points, inspect your source data and establish the terrain beneath your design.
SURVEY & TERRAINDevelop alignments, profiles, corridor definitions and grading with explicit design controls.
ROADS & GRADINGInspect geometry, source dependencies and quantities as the design takes shape.
REVIEW & ITERATECivzu is in active development. Feature availability varies between the desktop preview, native tools and prototype screens.
At the desk or away from a reliable connection, your core workspace stays on your computer. Civzu’s project foundation stores design data locally.
We’re planning a local MCP server to connect compatible AI assistants to Civzu. The aim: less repetitive setup, easier project inspection and engineering commands you can review.
Planned feature. Not included in today’s download. Client compatibility, permissions and commercial plan availability are still to be finalized.

Preview details & checksumThe engineering workbench runs locally on Windows. This website introduces the product and provides the desktop download.
The core desktop workflow and local project files are designed for offline use. You need a connection to download the preview. The package includes its .NET runtime.
Not yet. This is a development preview. Features, engineering validation and interface refinement are still in progress. It is intended for evaluation, not final construction or regulatory deliverables.
Yes. They are captures of Civzu’s visual prototype, showing independently generated demonstration scenes. They are not screenshots of validated engineering results. The current build may look different as the interface develops.
Civzu is a commercial product. Proposed launch pricing is R990/month for Pro and R2,490/month for Studio with three named users. Annual plans cost the equivalent of ten monthly payments. Paid plans are not on sale yet; the current download is an evaluation preview. See Pricing for scope and launch details.
This preview package is for Windows x64. Downloads for other operating systems are not currently offered.
