These two terms are interchangeable with the term laser scan survey which is used to capture the data on from which a 3D BIM model can be constructed. These measured surveys deliver an accurate based model that architects can use as the foundation for the design of a BIM project.
BIM (Building Information Modelling) is a broad term used to describe the process used for creating and managing digital information about a property or site and work collaboratively during the lifecycle of a project.
BIM standards
As with CAD standards, BIM standard align working practices to ensure continuity in projects and because BIM is a collaborative process it can have a big impact on productivity and ensure BIM implementation is effective, efficient, and sustainable.
PAS 1192-2 is a framework for project information management when using BIM. It defines the graphic ‘Level of Detail’, and data ‘Levels of model Information’ (LOI) in a 3D model.
ISO 19650 is the new international standard for managing information over the life cycle of a building or asset when using BIM. It contains all the same principles and high-level requirements as UK BIM Framework and is closely aligned with 1192 standard.
