RZI Software

What RZI Software does

RZI Software GmbH, headquartered in Ahrensfelde, Germany and operating as a subsidiary of the IB&T Gruppe, develops the RZI Tiefbau product family — a modular suite of civil engineering software that runs as a native plugin inside the AutoCAD, AutoCAD Civil 3D, AutoCAD Map 3D, and BricsCAD platforms. The suite covers the full civil engineering workflow from preliminary surveying and digital terrain modeling through road, sewer, canal, water, and utility-line planning to construction invoicing and quantity calculation, with add-on products for swept path analysis (smartTurn, easyTrack — the latter co-developed with GOLDHOFER AG) and cost estimation according to AKVS standards (Kosten AKVS/elKe). The Mein RZI dashboard provides centralized license management and product access across the portfolio, and the software is used by German engineering offices, surveying firms, municipalities and building authorities, construction companies, and heavy-transport planners, with 3,150+ workstations deployed.

The company's technology architecture is centered on deep CAD-platform integration: RZI Tiefbau operates natively within the host CAD environment, avoiding format conversion and enabling standardized data exchange via formats such as LandXML, ISYBAU, ALKIS/GeoInfoDok, and NTv2 coordinate transformations. The modular licensing model allows customers to purchase only the modules relevant to their work (e.g., surveying, road planning, sewer planning, quantity calculation), and easyTrack differentiates via support for unlimited heavy-haul vehicle configurations with automated collision detection, while smartTurn provides dynamic swept path analysis for standard and specialized vehicles.

Commercially, RZI generates revenue through three streams: one-time perpetual software licenses (Classic, Pro, and Test license types with hardware dongle or file-based activation), recurring annual maintenance contracts that grant access to updates and the 24/7 Support Center, and fee-based training seminars and consulting. Go-to-market is sales-led with direct website sales, free trial downloads via the IB&T Cloud, TeamViewer-based remote presentations, a regional sales network across Germany, and an annual infraTage webinar series. The company is privately held with no disclosed funding rounds, no public revenue figures, and operates within the IB&T Gruppe's portfolio of infrastructure-software businesses.

Core offering

RZI Software GmbH develops and sells the RZI Tiefbau product family, a suite of CAD-based civil engineering software plugins that run natively inside AutoCAD, Map 3D, Civil 3D, and BricsCAD. The modular suite covers surveying, ALKIS cadastral data, digital terrain modeling, road planning, canal/sewer planning and cadastre, hydraulic engineering, construction invoicing, and quantity calculation. The company additionally offers the smartTurn and easyTrack swept path analysis tools and the Kosten AKVS/elKe cost estimation software, plus the Mein RZI central management dashboard.

Product overview

RZI Software develops the RZI Tiefbau product family, a comprehensive suite of civil engineering software modules that operate as plugins for AutoCAD, Civil 3D, Map 3D, and BricsCAD. The platform follows a modular architecture where users can combine products according to their needs: core surveying, transformation, and ALKIS modules; digital terrain modeling (DGM); construction invoicing and quantity calculation (Mengenermittlung); infrastructure planning including road (Straßenplanung), canal/sewer (Kanalplanung Pro, Kanalkataster Pro, Kanalsanierung), water engineering (Wasserbau), and utility lines (Leitungsplanung Pro); cost estimation (Kosten AKVS/elKe); and swept path analysis via smartTurn and easyTrack. The Mein RZI dashboard provides centralized access to all products. The software supports over 3,150 workstations across engineering offices, surveying firms, municipalities, and construction companies.

Broad incumbents

• Trimble Novapoint: Trimble's Novapoint (and broader infrastructure portfolio) provides road, rail, and tunnel design CAD tools across Europe, including Germany. It is a broad incumbent competitor to RZI's infrastructure planning modules.
• Autodesk Civil 3D / InfraWorks: Autodesk owns the underlying AutoCAD, Civil 3D, and Map 3D platforms on which RZI is built, and competes directly with RZI through its own native infrastructure features. It is a broad incumbent across AEC and the most strategically consequential peer.
• Bentley Systems (OpenRoads, OpenFlows): Bentley offers OpenRoads for road design and OpenFlows for sewer/water networks - direct functional alternatives to RZI Tiefbau modules. As a large AEC platform incumbent, it competes across the same engineering-office and municipal customer segments.

Direct peers

• AKG Software Consulting (VESTRA): AKG Software's VESTRA line is one of the most established German infrastructure CAD suites for road, rail, sewer, and water planning. Like RZI, it operates as a plugin over AutoCAD/BricsCAD with strong municipal adoption in the DACH market, making it the closest direct competitor.
• ProVI GmbH: ProVI provides road and infrastructure planning software for AutoCAD and BricsCAD in the German market, with municipal and engineering-office focus comparable to RZI's Straßenplanung and related modules.
• IB&T Card/1 (IB&T Gruppe): Card/1 is a sibling product within the IB&T Gruppe, offering road, sewer, and water planning CAD software for the same German infrastructure market. As a fellow subsidiary targeting overlapping customers, it is the most direct intra-group comparable despite the shared parent.
• Transoft Solutions (AutoTURN): AutoTURN is the leading swept-path analysis product for AutoCAD/BricsCAD, competing head-to-head with RZI's smartTurn product line. It is the most direct competitor in the swept-path subsegment RZI addresses.
• BARAL Straßen- und Tiefbau Software: BARAL develops German infrastructure planning software (road, sewer, water) tightly integrated with AutoCAD and BricsCAD. It serves the same DACH engineering offices, surveying firms, and municipalities as RZI, with comparable German-standards compliance.
• Carlson Software (Civil/Survey): Carlson offers civil engineering and surveying CAD software (Carlson Survey, Carlson Hydrology, Carlson Civil) with AutoCAD and IntelliCAD/BricsCAD compatibility. It overlaps RZI's surveying and infrastructure modules, particularly for survey offices.

Others

• Bricsys (BricsCAD): Bricsys is the platform partner that provides the underlying BricsCAD engine on which RZI ships modules. It is also an adjacent competitor in CAD platforms and could expand vertically into infrastructure features overlapping RZI's scope.
