Allplan

Allplan is an integrated Building Information Modeling (BIM) CAD software platform designed specifically for the Architecture, Engineering, and Construction (AEC) industry. you can try these out Developed by Nemetschek Allplan—a core brand of the German software giant Nemetschek Group—Allplan serves as a unified environment supporting the entire lifecycle of a building or infrastructure asset, from initial conceptual drafting to detailed structural design, prefabrication, site planning, and facility management.

While many CAD tools cater to either pure architectural modeling or structural engineering, Allplan distinguishes itself by offering a cross-disciplinary, object-oriented design framework. It allows architects, civil engineers, structural engineers, and precast detailers to work within a single modeling environment. Built on an open-BIM philosophy, Allplan emphasizes interdisciplinary collaboration, precision, and constructability.

Historical Context & Development

Allplan was originally created in the early 1980s by Professor Georg Nemetschek as an in-house engineering and drafting tool. Over four decades, it evolved from a simple 2D drafting utility into a comprehensive 3D object-oriented BIM system.

Unlike legacy software programs that added 3D functionality onto existing 2D CAD engines, Allplan was engineered early on around spatial geometry and parametric data structures. Today, as part of the Nemetschek Group portfolio—alongside tools like Archicad, Vectorworks, Solibri, and Bluebeam—Allplan serves as a primary engine for heavy structural design, reinforced concrete detailing, complex civil engineering, and digital construction workflows.

Core Capabilities Across Disciplines

Allplan is structured to accommodate the distinct requirements of different phases and trades in a construction project.

1. Architectural Design

For architects, Allplan provides flexible modeling options ranging from freeform 3D curves to parametric architectural elements like walls, slabs, roofs, and intelligent openings.

Flexible Workflows: Designers can transition fluidly between 2D drafting, 2.5D schematic layouts, and full 3D object-oriented modeling.
Variant Comparison & Visualizations: Architects can rapidly prototype multiple design iterations, test spatial layouts, and generate photorealistic renderings directly within the platform using integrated rendering engines.
Automated Documentation: Floor plans, elevations, section views, and quantity schedules automatically update whenever changes are made to the 3D model, ensuring cross-sheet consistency and reducing drafting errors.

2. Structural & Civil Engineering

Structural engineering is one of Allplan’s strongest areas, particularly for cast-in-place concrete, post-tensioned systems, and steel construction.

3D Reinforcement Detailing: Allplan features automated reinforcement tools that allow engineers to place, adapt, and detail complex rebar arrangements directly inside 3D concrete elements.
Automated Bending Schedules: Bar-bending schedules, mesh lists, and material quantities are generated instantly from the 3D model. Modifications to structural dimensions automatically adjust rebar counts and lengths, eliminating manual re-calculations.
Structural Analysis Integration: Through structural analytical models (SAM) and direct interfaces with analysis software (such as SCIA Engineer and Frilo), Allplan seamlessly bridges the gap between geometry design and structural calculations.

3. Infrastructure & Bridge Design

Through specialized modules like ALLPLAN Civil and ALLPLAN Bridge, the software provides advanced parametric road, terrain, and bridge modeling capabilities.

Parametric Alignment: Infrastructure models adapt automatically when alignment axes, cross-sections, or elevation profiles are adjusted.
Integrated Analysis: ALLPLAN Bridge unifies structural modeling, tendon placement, construction stage calculations, and structural code checks into a single parametric model.

4. Prefabrication & Offsite Construction

For precast concrete manufacturers and modular builders, ALLPLAN Precast offers tools to convert architectural geometry into detailed, production-ready precast elements.

Automated Shop Drawings: Converts designs into precise production data, element books, and shop drawings.
CAM Machine Data Export: Directly interfaces with modern manufacturing machinery (e.g., automated mesh welding units, shuttering robots, and concrete distributors) for seamless offsite fabrication.

OpenBIM Commitment & Interoperability

Allplan is built on OpenBIM principles, supporting open data formats like IFC (Industry Foundation Classes), BCF (BIM Collaboration Format), SAF (Structural Analysis Format), and DWG/DXF. This allows teams using Allplan to collaborate seamlessly with partners operating other BIM platforms (e.g., Revit, Tekla, or Archicad) without losing data integrity.

Integrated Cloud Ecosystem (Bimplus)

Through ALLPLAN Cloud services and Bimplus, project teams can share central coordination models, track revisions, run clash detections, and manage issues across web browser interfaces. This cloud connectivity extends to construction sites via “BIM2Field” workflows, allowing field contractors to view detailed models, review installation sequences, and verify reinforcement layouts directly on mobile devices or tablets.

Precise Quantity Take-Off & Cost Control

Allplan links geometric components directly to material properties, costs, and specifications. This capability enables fast and accurate automated Quantity Take-Offs (QTO). Because quantities are derived directly from the underlying BIM objects, estimators can generate accurate cost projections, tenders, and material order lists early in the design phase.

Benefits of Using Allplan

Aspect	Benefit	Impact
Design Quality	Associative views ensure model updates reflect across all floor plans, sections, and schedules simultaneously.	Eliminates drawing discrepancies and minimizes design errors on site.
Engineering Speed	Automated rebar distribution and bar-bending schedule generation.	Reduces structural detailing time by up to 50–90% compared to 2D methods.
Constructability	True-to-scale 3D modeling of complex geometry, tendons, and embedded parts.	Resolves geometric collisions prior to construction, minimizing rework.
Multi-Material Support	Handles cast-in-place concrete, precast concrete, structural steel, and timber within one model.	Streamlines hybrid material construction projects.

Allplan vs. Competitors

While tools like Autodesk Revit dominates general architectural BIM markets in North America, Allplan is widely recognized as a market leader in Central and Western Europe, particularly for structural engineering, civil infrastructure, heavy reinforcement, and precast fabrication.

Revit vs. Allplan: Revit relies heavily on third-party add-ons for heavy concrete reinforcement and bridge design. Allplan includes native, highly optimized 3D rebar engine capabilities and specialized parametric infrastructure workflows out of the box.
Tekla vs. Allplan: While Tekla Structures focuses primarily on steel detailing and precast structural elements, Allplan offers a broader end-to-end framework that covers architectural conceptualization, civil engineering, precast, and general structural design within a single ecosystem.

Conclusion

Allplan is a comprehensive design-to-build BIM platform. By uniting architectural design, structural engineering, infrastructure modeling, and precast fabrication within an OpenBIM framework, it bridge the traditional gaps between project phases. For AEC professionals seeking precision, constructability, and streamlined data handoffs from the drawing board to the construction site, a knockout post Allplan remains a reliable solution driving digital transformation across the built environment.
