Why Architects Use LiDAR Scanning Before Starting a Remodel
Remodel design starts with a building that already exists. Before exploring a new layout, the architect needs to understand the spaces, connections, and constraints that the project will work with.
LiDAR-based documentation can contribute to that starting point. Its value is not that it makes design decisions automatically, but that it provides a measured reference for the team responsible for making them.
Establish a shared existing-condition base
Autodesk identifies point clouds as a visual reference for modeling existing buildings. In a remodel workflow, that reference can support the preparation of the base model used to develop design options. 1
Agree on the required coverage before capture. A proposed opening may relate to adjoining rooms; an addition may require context from more than one level. The useful brief follows the design questions, not only a list of room names.
Revisit captured geometry as questions develop
An architect may later want to examine a ceiling transition, a stair relationship, or an opening that was not central to the first design discussion. Where the relevant surfaces were captured at suitable detail, the dataset can provide another reference to consult.
FARO's As-Built software describes workflows for extracting drawings and comparing design information with captured conditions. Those capabilities depend on the available data and the chosen workflow; they should not be interpreted as a promise that every clash or construction issue will be detected. 2
Choose the handoff that fits the design team
Some practices prefer to create their own model from a registered point cloud. Others want an editable CAD base or an authored Revit model. Ask who will perform each step, rather than assuming scan collection includes all subsequent drafting and modeling.
Spot On Measure offers scan-only capture as well as drawing and model deliverables. The handoff should be selected to fit the receiving team's workflow. 3
For a model, specify the software requirements, included elements, level of detail, and treatment of uncertainties. For scan data, confirm the file format, units, positioning expectations, and included areas.
Preserve the boundary between documentation and design
A captured surface does not establish the structural role of an element or prove concealed construction. The design team must identify questions requiring further investigation and determine what licensed professional review is necessary for the proposed work.
The same principle applies to critical dimensions. Use the documentation as the agreed reference, then perform the checks appropriate to the downstream task. A visually complete model should not hide uncertainty.
Preparing a remodel and need an existing-condition base? Send Spot On Measure your documentation brief. Include the areas, required files, key features, and intended use so capture and delivery support your design process.
