BIM reference

BSI (2020), “Medical-Dental Test Files,” buildingSMART International. The dataset describes an anonymised real two-storey clinic, with discipline models prepared for interoperability demonstrations. Used under CC BY 4.0.

We converted the architectural, HVAC, electrical and plumbing IFC geometry into a lightweight web format. Element IDs, types, names, storeys and model coordinates are retained. The plan is a section through that geometry at +1.35 m. Materials, clipping and camera positions are display adaptations. The reference is not a site scan, a construction drawing for execution or evidence of installation.

BCF export follows the buildingSMART BCF 2.1 XML schemas. It includes the selected IFC GlobalId, camera in model coordinates and a snapshot. fflate is used under its MIT licence.

Real capture reference

LivingBIM (2024, v3), Abdullah Alsuhaibani, Jennifer Rojas, Caitlin Leffel, Jong Won Ma and Fernanda Leite, University of Texas at Austin and Concordia University. Used under CC BY 4.0. The dataset contains as-designed BIM, as-built point clouds and panoramic photography of a recently constructed academic building.

The Site review view uses the L2_HW hallway scan and its associated L2_HW_IFC model. The original scan contains 47,324,148 points; the browser retains every 31st source point (1,526,586 points), shuffles them for display and quantises positions for transport. The mobile overview uses 763,293 of those points. Local detail clouds retain every tenth source point within 8 m of each capture station (1.6–2.4 million points per region); smaller screens load separate files containing every second point, reducing the geometry transfer size by half. The Digital twin view uses surface meshes built from the full 47,324,148-point scan, with vertices at measured source positions. Neighbouring angular samples are triangulated only when present and within a distance-dependent edge limit capped at 0.20 m; missing cells are not filled. Desktop loads 2.3–2.9 million triangles per station, with 0.57–0.72 million on narrow screens, coloured by projection of the corresponding reference panorama. Camera heading is visually registered, not survey calibrated. Textured surfaces are an inspection visualisation, not trained Gaussian splats or validated OpenWork sensor-fusion output. The underlying point cloud keeps its original RGB colours. Measurements still snap to displayed source points, not interpolated surface triangles. The IFC view contains 480 rendered elements. The five original panoramic photographs and exported station positions are used for linked navigation. Panorama heading is aligned to scan colours for viewing. The clinic design explorer and this academic-building capture are separate references. Work-package quantities, updates, due dates and open issues are editable example workflows, not documented defects or progress claims.

The scan is rigidly aligned to architectural surfaces for visual comparison. The alignment is not independently survey validated. Clipping, colours and camera positions are display adaptations; unobserved geometry remains unfilled. Measurements use displayed scan coordinates. These views do not establish construction tolerances, detected defects, acceptance or OpenWork capture accuracy.

Photographs remain the property of their respective owners. They are shown as attributed references to real construction environments, not as OpenWork deployments or endorsements. Images have been resized and cropped for display. The binary graphic treatment is decorative; it does not represent measurements or a reconstruction.

Development imagery

The six images in See our progress are AI-generated hardware and workflow concepts. They are not photographs of completed prototypes, deployment evidence or captured 3D output.

Hardware concept

The helmet image is an OpenWork industrial design concept. It illustrates the proposed sensor integration, not a released or certified protective product. The hardware and software architecture described on the platform page is under development.

Company marks

Partner marks were obtained from their official websites: Deutschland Technology, ACS Group press kit, BI-COM, Aleph Developments, and Construcciones San Martín. The Aleph symbol and wordmark follow its website’s SVG and text treatment. Marks remain the property of their respective owners.

AutoCAD, Revit and Procore are mentioned as the project tools the planned product is designed to work alongside. No certified integration or endorsement by those companies is claimed.
