How to Choose a Building Survey and BIM Service Provider
Criteria for selecting a building survey, point-cloud and BIM provider based on purpose, accuracy, deliverables and quality assurance.
Compare providers against the same technical brief. A low survey price can become expensive if the output cannot support the next design or operational task.
Method and purpose
The provider should explain why manual measurement, static scanning, mobile SLAM, photogrammetry or surveying control is appropriate.
Accuracy statement
Require measurable tolerances and an independent verification method. Avoid vague claims such as 'laser accurate'.
Deliverables and rights
Specify native and open files, point clouds, editability, licences, data ownership, storage and confidentiality.
Quality process
Ask about unresolved areas, model-to-cloud checks, peer review and handling of inaccessible spaces.
Whole-life cost
Include remobilisation, coordination, georeferencing, service modelling, revisions and future updates.
Need deliverables that remain usable
Before commissioning the work, define the purpose, survey scope, required accuracy, deliverable formats and acceptance checks in writing. DigiStav provides surveying, building records, 2D documentation, point clouds and BIM-ready outputs for buildings, infrastructure and industrial assets. The scope should always follow the intended use rather than a generic package.
