Scan-to-BIM: From Survey to As-Built Model
The value of a BIM model of a building or infrastructure lies in how closely it matches reality. Starting with a survey using a laser scanner and a drone, we obtain an accurate and verifiable as-built model: not a theoretical drawing, but the structure as it actually is, ready for the design of improvements, maintenance, and management. We coordinate the process from survey to model and verify its consistency, ensuring that the data holds up during the design phase and the bidding process.
What is it used for, in detail?
A reliable as-built drawing is the foundation on which technical and administrative decisions are based. Specifically, it serves these purposes.
Planning Interventions
Modeling of architectural, structural, and mechanical/electrical systems based on actual measurements, for maintenance, retrofitting, or renovation. A model that accurately reflects the existing structure prevents errors that arise from theoretical or outdated drawings.
Verify that the construction was carried out in accordance with the permit
Compare what was actually built with what was designed, using metric measurements. This verification process gives the as-built documentation legal and technical validity, in addition to its documentary value.
Managing Assets
An updatable model that supports the project over time, for maintenance and management. The data does not become obsolete after its first use: it remains a living foundation on which to build over the years.
Bids and Specifications
Bidding documents, specifications, and BEPs compliant with UNI 11337 and ISO 19650 standards, for contracting authorities and companies subject to BIM requirements.
For those who
As-built drawings are useful for those who need to deliver, verify, or manage a project based on reliable data.
Contracting Authorities
Who manage projects subject to BIM requirements and must establish consistent specifications.
Companies and Designers
They must submit a verifiable as-built drawing upon completion of the work.
Asset Managers
They want an updatable version of the existing model for management purposes.
Based on our findings
How We Work
We prepare the as-built survey of the structure, coordinate the creation of the digital model in a shared environment, and verify its consistency with the survey data and the required standards. The result is a consistent and updatable model, delivered in a format suitable for design, management, or bidding.
