CHEK’s DBP software stack
CHEK delivers a suite of interoperable software tools that support every stage of the digital building permit processes spanning from design phase to regulatory review. Built on open standards like IFC and CityGML, these tools are modular, practical, and designed to meet the real needs of both designers and municipalities.
CHEK’s DBP software stack is result of joint effort, a cross-disciplinary collaboration in order to deliver practical, scalable, and innovative solutions that advance the digitalization of permitting processes across Europe.
| Tool name | Partner | Description |
|---|---|---|
| API REST | CYPE | The API REST for BIMserver.center is an Open API that provides the necessary framework for any software or service to access and manage data in BIMserver.center platform. The API will facilitate communication and interoperability between the different tools and services that CHEK will provide for the digital building permit process. |
| Bimserver.center | CYPE | BIMserver.center Validation provides a framework for public and private institutions which daily work is dealing with building permitting processes. BIMserver.center Developers is specific part of BIMserver.center from which any software developer can manage access to BIMserver.center from their applications through the API. |
| CYPEURBAN | CYPE | CYPEURBAN is a free program for carrying out urban planning compliance documents on BIM models in IFC format. The program includes logical calculation which allows users to obtain some of the urban planning checks required by municipal bylaws from the BIM model. It also includes a series of tools for defining and checking parameters such as distances from the building to adjoining plots, plot checks, occupancy, buildability, crown height and free heights, among others. |
| Open BIM Accessibility | CYPE | Open BIM Accessibility is a tool for the analysis and verification of accessibility requirements in building projects. The application allows the customization of the regulatory accessibility requirements to be examined. The software imports IFC models to check against accessibility rules. |
| Open BIM Site | CYPE | Open BIM Site is a free application for defining the initial conditions of a project site. Using this tool, users can establish the geographical location of the models, manage different types of maps, enter topographic surfaces and add elements specific to the site, such as parcels and buildings. |
| IFC Digital Signature | DiRoots | The IFC Digital Signature core service includes two main components: the IFC signing and the signature validator. Designed with a modular, decoupled architecture, this service supports a variety of integrations and workflows.
The IFC signing component retrieves necessary data from an IFC file to secure a digital signature from supported providers, which is then attached directly to the file without altering its structure. The validator module enables compliant IFC files to display a visual indicator of the signature’s validity, ensuring the file has not been tampered with and maintaining trust between the creator and user. This flexible system is compatible with any eIDAS trusted provider for strong legal compliance and can also integrate with bespoke in-house solutions, enhancing its adaptability for secure digital practices. |
| IFC Exporter | DiRoots | The CHEK IFC exporter tool helps the user to easily export their models from their BIM authoring software (Revit or ArchiCAD27), based on the predefined Information Delivery Specification (IDS) files for each municipality of Lisbon, Gaia, Ascoli Piceno, and Prague.
The IDS-based IFC exporter simplifies the export process by eliminating the need for complex, time-consuming, and error-prone manual configurations. This tool allows users to easily configure IDS requirements and accurately map the required IFC data for each municipality, making the export workflow more efficient. |
| IFC to CityGML | TU Delft | The software is able to extract the outer shell of an ifc file and store it as CityJSON file. It will help the automated conversion between scales. something that is seen as challenging with current software |
| IFC Georeferencing | TU Delft | IFC Georeferencing tool will help with georeferentiation of IFC files during the Digital Building Permit Process. |
| Plugin CityJSON to Revit (Coming soon) | TU Delft | The new software solution is a plugin for Autodesk Revit, aimed at harmonizing 3D city models and Building Information Models (BIM) in the context of GeoBIM. Its primary purpose is to enable the integration of 3D geographic data from CityJSON into BIM projects. It promotes better interoperability, informed decision-making, and efficient data management in the CHEK project. |
| Verify 3D | Xinaps | Verifi3D is a SaaS (cloud-based), rule-based model checker with a scheme for integration with other cloud services and support for openBIM workflows. Verify 3D will building permit related rules on our product as rule templates and integrate our product with the CHEK platform. |
| VC Map + VC Map CHEK plugin | VirtualCity Systems | The VC Map is a browser-based application to show 2D and 3D spatial data as well as oblique imagery in one unified viewer application. The application provides a set of tools such as measurements in 2D/3D, drawing tools, split-screen, transparent terrain mode, real time shadows, clipping planes, camera paths, share link, image/PDF export, and others more, which allow users to explore and work with the shown datasets. The software will provide the geospatial environment that is required to perform checks that require spatial context information such as parcels, 3D buildings, terrain, etc. |
| CityGML to IFC, IDS | RDF | CityGML / CityJSON to IFC converter will be based on the Semantic Web based Geometry Modelling Kernel library and inherits all API calls and functionality, library named ‘GISEngine’ + IDS validator will be based on the IFC / STEP Engine (with generic EXPRESS schema validator) |
| BIM+GIS Viewer (IFC+CityGML) | RDF | BIM and GIS viewer connected to the platform BIMserver.center that facilitates and combine the visualization of IFC, CityJSON and CityGML formats under the same viewer. |
| OGC Data exchange toolkit and OGC RAINBOW | OGC | Support data requirements definition for geospatial data in aligned human and machine readable format, and related validation. It provides a solution for data requirements provision for standard-based geospatial information and (geo)data validation |
| CHEK change virtual assistant | Fraunhofer Italy | CHEK – Change management virtual assistant. Interactive web-based tool to support municipalities in assessing their level of maturity, their objectives, setting up their customized strategy and implementation plan to go through the digital transformation process. Will include functionalities and features like: chatbot assistant, assessment tool, process map generator/visualizer, roadmap generator, maturity matrix calculator. |
