Scan to BIM services for existing buildings

Older drawings rarely answer every question a refurbishment team has. Room layouts may have changed, equipment may have moved and services may occupy space that a design drawing shows as clear. A point cloud records surveyed surfaces; a BIM model turns the agreed parts of that information into elements that can be reviewed, coordinated and documented.

Our Scan to BIM service starts with the point cloud and supporting information you provide. We agree which building areas and disciplines belong in the model, what detail is useful and which uncertainties need to remain visible. That gives architects, consultants and contractors a defined reference for the next stage, rather than a model whose apparent detail hides gaps in the source information.

Start with a representative point-cloud sample or a description of the available survey, the building location, approximate extent and intended use of the model. Include any existing plans, sections, model files or survey notes that explain the building. Tell us which areas are essential, which areas are excluded and whether access restrictions have left gaps in the capture.

State your required Revit version, any IFC exchange requirement, the project coordinate system and the model breakdown your team expects. If you have a BIM execution plan or an information requirement, share the relevant sections. We review the proposed file handoff before confirming the work, including whether the supplied data is suitable for the requested scope.

Accuracy requirements need to be stated for the actual task. A model intended to establish spatial context has different acceptance criteria from a model used to check a tightly constrained installation. We agree the required modeling approach and review criteria with you instead of applying an unsupported universal tolerance or promising detail that the scan cannot show.

The final package is defined by the commission. It can include a Revit model, an agreed IFC exchange, as-built drawing outputs and a record of unresolved source-information questions. Specify the required drawing views, sheets or schedules at the outset, because a usable model and a complete documentation package are not automatically the same deliverable.

Where existing services need to be coordinated with proposed work, the model can form an input to a separate MEP coordination package. That work needs its own design references and review responsibilities. An existing-condition model records the agreed interpretation of supplied information; it is not a substitute for a new survey, design approval or site verification of a critical installation interface.
