EVOLUTION OF BUILDING INFORMATION MODELING
Transcript of EVOLUTION OF BUILDING INFORMATION MODELING
BUILDING INFORMATION MODELING Vector CAD Object CAD BIM progression CURRENT improvements First generation of CAD (Computer-Aided Design) Object were added to CAD, which were able to be pulled from a file and fit into a drawing. automated building code checking system
fire code requirements, energy efficiency codes, disability Vector based lines, arcs and circles represented buildings with geometry.
easy to modify and greater precision then pencil Which allowed information about a particular object such as part numbers, finish, the supplier and so on.
The objects were "Smart". They would adjust to the dimensions of the building. Before BIM Separate drawings for architectural, mechanical, plumbing, electrical and civil.
Each plan describes a different piece of the project, and reflects many organizations such as architects, engineers, consultants, subcontractors and manufacturers. 2D - which is a simple vector drawing. 2D is still the main drawing when used in contracts.
3D - a digital representation of physical and functional characteristics. Allows the identification of clashes that may have been overlooked.
4D - a 3D model linked to a schedule. Which can be more precise productivity rates using a BIM model. Provides cost-loaded schedules for the owner.
5D - integrates the 3D drawing with time and cost estimates. 5D explains what happens if a change is made to the schedule and budget.
6D - Building life cycle management information such as specifications, shop drawings, and RFI's can be found by clicking a particular portion of the building. Integrated Building Plan and Service (IBP/IBS) checking system, is a system currently being developed for an automated code-checking process. Documentation in BIM New applications in Autodesk 360 Whole Building Energy Analysis
includes air flow, fluid flow and thermal comfort, allowing a better understanding of flow patterns. Mechanical simulation
highlights potential points of failure and validate the long term durability of components in steel and concrete Plan Rack references Goedert, J. and Meadati, P.
