Speckle, a platform from UK-based company AEC Systems for working with model data across architecture, engineering, and construction, has introduced an AI layer that lets users ask questions about BIM and AEC model data to generate reports and run checks.
The assistant runs read-only queries against model data already published to Speckle rather than relying solely on PDFs or separate exports. Users can trace answers back to the underlying information, letting them check results before using them in project work.
The launch includes a major rebuild of Speckle’s data architecture and 3D viewer, designed to handle much larger building, civil, and infrastructure models in a web browser.
AI queries build on earlier model checking tools
The AI layer targets jobs that often involve aggregating information from several applications. Users can query published model data to compile reports, inspect information and prepare material for client deliverables.
Speckle had already been developing tools to analyse model information before introducing conversational queries. Speckle Intelligence, introduced in August 2025, brought model, project and portfolio analysis to the platform, including version comparisons, project metrics and validation against project standards and historical baselines.
Validation functions continued to develop in 2026. Model validation was added to the Speckle Intelligence dashboards in February, followed in May by a broader Model Validation beta for model data validation.
The new AI assistant offers another way to interrogate that information. Examples given by Speckle include identifying missing fire ratings, inconsistent naming and broken parameters. Because queries run against data published from the model, users can check the source information behind the response rather than working only from a separate PDF or export.
WSP was already using Speckle for structural checks
WSP’s UK Structures team, which had already been using Speckle across structural design and analysis, had worked on the new Tekla Structural Designer connector.
The engineering consultancy uses Speckle as a shared layer across Revit, Tekla and ETABS, moving some validation out of individual authoring and analysis applications. According to Speckle’s account of the deployment, checks including span-to-depth ratios, model health and compliance rules can be run without opening ETABS or Tekla directly.
WSP also replaced a PDF-based process for updating parameters such as fire ratings and reinforcement values. Engineers enter the information into Speckle before technicians apply the updates.
The Tekla Structural Designer connector adds another structural analysis source to the setup.
Rebuilt viewer takes on larger AEC models
Speckle has also reworked the database architecture supporting its analytical model and browser-based 3D viewer.
Large federated building, civil and infrastructure models can contain extensive geometry, alignments and corridors, placing heavy demands on browsers and computers without dedicated graphics hardware. Speckle has introduced a new data model and packfile architecture to handle larger datasets and says it is already testing models with billions of triangles internally.
The company says the changes are intended to make these models more accessible to site teams, field engineers and reviewers who may not have dedicated workstations available.
New connectors widen access to project data
The release adds a Bentley ProjectWise integration that supports publishing geometry and data from OpenRoads, IFC, Revit, Civil3D, Navisworks and Tekla file formats into Speckle for analysis, validation and coordination.
Speckle has also introduced the Tekla Structural Designer integration, developed with WSP’s UK Structures team and Trimble. It joins ETABS as one of the platform’s structural analysis connectors, publishing analysis results to Speckle for validation and automation.
The structural analysis integrations are publish-only, moving results to Speckle for review and validation rather than sending information back to the analysis application. Speckle said the Tekla Structural Designer integration will be enabled by Tekla for all TSD users in mid-September with the release of TSD 2026 Sp3.
Tom Sargent, senior engineer at WSP, said the team had identified three main uses for the connector: linking analysis data to external design applications, connecting analysis and BIM models via Speckle’s automation engine, and creating dashboards for reviews, insights and client presentations.
Speckle has also updated its Power BI connector. Rather than loading a fully expanded model table by default, it loads only the required data, while the 3D visual streams geometry as information arrives. In Speckle’s own benchmark tests, the updated connector and 3D visual loaded up to 50 times faster.
The AI and performance updates are now live for hosted Speckle users. Self-hosted Enterprise customers will receive them separately, while self-hosted open-source users will remain on the current viewer until the new version is released for their deployment.
