1) Introduction to BIM Flashcards
Learn BIM theory
What does the abbreviation of BIM stand for?
BIM stands for ‘Building Information Modelling’.
What defines BIM?
2 points
Process of designing, constructing or operating a building asset using electronic obect-orientated information.
Use of shared digital representation of built project - facilitating design, construction and operation processes - to form reliable basis for decisions.
What is not BIM?
4 points
Models containing 3D data only, with no object attributes.
Models with no support of behaviour (no adjustments when changes are made).
Models composed of multiple 2D CAD reference files - that need to be combined to define a building.
Models that allow changes to dimensions in 1 view, that doesn’t then change in other views.
What is BIM?
4 points
BIM platforms and tools (e.g. Revit but there is many softwares that can be used).
BIM processes to produce, communicate and analyse models.
Parametric object modelling.
Support for project team collaboration - CDE (common data environment).
What makes up the final BIM model?
3 points
Graphical data (shape it is, collision of elements etc).
Non-graphical data (properties/materials, relationship with other components).
Documents (Specifications, Reports, Drawings)
What is the difference between BIM and CAD models?
CAD is not clever drawing
BIM provides information on all aspects of the building.
design, construction, operation, schedule, cost etc
What information makes up a BIM object?
A BIM object has; type, properties, geometry, visualisation data, functional data.
Who benefits from BIM?
Everyone involved in the life cycle of the building.
Client, Design Team (including engineers), Contractors, Consultants, General Public.
Why do we use BIM?
Removes errors; information loss diagram for Design, Tender, Construction, Operation phase.
Cost predictability (45%-70%)
Time predictability (to 70%)
Accidents/Fatalities Decrease
Benefits of BIM; to Owners?
Owner; (pre-construction)
Concept, feasibility and design
Improved collaboration using integrated project delivery
Benefits of BIM, to Designers?
Designers;
Earlier and more accurate visualisation
Generation of accurate and consistent 2D drawings at any stage
Easy verification of consistency - clash detection
Benefits of BIM; to Builders?
Builders?
Use design models to fabricate components
Discovery of errors
Quick reaction to changes
