Scan-to-BIM and as-built drawings for a spa and wellness facility in the US

ORIGIN developed an As-Built BIM model for a spa and wellness facility based on extensive point cloud data. The scope covered the building’s architectural and structural elements, including interior layouts, exterior facades, roof geometry, and surrounding site conditions.

The model also captured several project-specific features: complex facade profiles, multi-level roof configurations, structural floor depressions for spa and hydrotherapy basins, interior FF&E, visible architectural lighting fixtures, and adjacent hardscape elements.

The final deliverable provided a coordinated LOD 300 Revit model and drawing set for documenting the existing facility and supporting future renovation or coordination work.

Managing a large, high-density point cloud covering both interior spa areas and extensive exterior facility zones required careful view management, point cloud segmentation, and element isolation to maintain efficient model performance.

Additional challenges appeared in areas affected by steam, reflective surfaces, and water within the spa basins. These conditions created incomplete or inconsistent scan data, requiring cross-referencing between multiple point cloud regions and careful interpretation of the available survey information to establish reliable geometry.

One of the most technically demanding aspects of the project was modeling the structural concrete floors. Unlike conventional commercial spaces, the facility included custom slab steps and deep floor depressions designed to accommodate hydrotherapy pools and specialized spa basins.

Accurately reproducing these floor elevation changes was essential for maintaining coordination between the structural geometry, spa equipment, and surrounding interior spaces.

The building features distinctive coastal Mediterranean Revival architecture that required a tailored modeling approach. The exterior includes curvilinear facade elements, sweeping arched storefront systems, and detailed decorative balustrades at roof level.

Reconstructing these elements from point cloud data required careful interpretation of curved geometry and consistent alignment with the surrounding building envelope.

The surrounding landscape was modeled using Revit’s native Toposolid tools rather than legacy topography methods. This approach allowed the site geometry to be integrated directly into the BIM environment, including grading, brick-paved walkways, pedestrian ramps, utility pads, and service-yard infrastructure.

Large utility elements, including distribution transformers and equipment pads, were incorporated alongside the architectural site features to provide a more complete representation of the existing facility.
