Building information modeling

Post by mim44 »

ou can use a point cloud to make a building information model (BIM) of your asset. A BIM is “a digital representation of physical and functional characteristics of a facility. A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle; defined as existing from earliest conception to demolition.”

Since a point cloud reflects a building’s “as-is” conditions accurately and comprehensively, this means it offers all the raw spatial data you need to create a new building information model or update an existing model. This enables you to compare the as-is conditions of the building against the “as-designed” to check for errors, conflicts, and clashes.

How it’s done: To generate a BIM from a point cloud, you would use a specialized BIM modeling software to generate the model on top of your point cloud data.

Some software enables you to do this manually by drawing elements and encoding information such as material. Other software can partially automate the process whatsapp database by recognizing surfaces, objects, and even MEP, and using AI to generate a model. These semi-automated processes can be very accurate, but they aren’t perfect—the software works much faster than humans do but can miss elements or return false positives. As a result, you will always need to check the work and do some manual correction.

3. Construction progress tracking
If you capture point clouds regularly while building progresses, you can use this data to keep track of what work is completed, when it is completed, and where.

How it’s done: There are manual methods for tracking construction progress with a point cloud, and advanced automated methods. You can share the raw point cloud data with stakeholders to give them access to a quick, high-level overview of the building’s progress at any point since building began. Or you can use automatic tools to provide more granular updates, for instance software that automatic analyzes the point cloud to recognize specific objects, and even goes as far as tracking work against specific trades, schedules, and budgets.
