Allplan 2026.1.3: Comprehensive BIM Solution for Architecture, Engineering & Construction

Allplan 2026.1.3 is a comprehensive Building Information Modeling (BIM) solution developed by ALLPLAN GmbH (a Nemetschek company) that covers the complete design-to-construction workflow for architecture, engineering, and infrastructure projects.

The 2026 release introduces AI-powered design assistance, cloud-based collaboration tools, enhanced sustainability workflows, and significant improvements in structural analysis, reinforcement detailing, and prefabrication . The 2026.1.3 hotfix (May 2026) delivers critical stability enhancements across terrain modeling, annotations, PythonParts, and teamwork workflows .

Allplan supports the entire project lifecycle—from conceptual design and early carbon assessment to detailed engineering, construction documentation, and fabrication. With native IFC4, IDS-based attribute import, and direct integration with the buildingSMART Data Dictionary (bSDD), Allplan ensures seamless Open BIM collaboration across disciplines.
