Unit 18: CADD in Construction Lesson Objective Be able to explain the use of Building Information Modelling in buildings

Unit 18: CADD in Construction Building Information Modelling Click to view Basic overview to BIM

Unit 18: CADD in Construction Background to BIM Increased competitive pressure Time Cost Quality Industry alignment Integrated practices Greater control over supply team Lean Practices Waste reduction Off site construction Building Information Modelling

Unit 18: CADD in Construction What are the aims of BIM? Faster and more economic delivery of projects with less environmental impact Create value in every stage of the process (Plan – Design – Build – Manage) User analysis to optimise sustainability of the life cycle. Visualise design ideas Simulate multiple alternatives -Ability to simulate projects before they are built (higher quality outcome) Identify clashes Communicate intent - Accurate documentation Improve productivity - Savings in time and money with improved coordination Building Information Modelling

Unit 18: CADD in Construction 8 Building Information Modelling BIM is not software!

Unit 18: CADD in Construction Software is a ‘Tool’ not BIM Building Information Modelling

Unit 18: CADD in Construction Autodesk –Revit –Autocad –Navisworks Graphisoft –Archicad Bently –Bently Arcitecture –RAM Steel Onuma –OPS Principal software companies… Building Information Modelling

Unit 18: CADD in Construction BIM is a methodology of gathering and maintaining information about a building for quick decision making throughout the life cycle or facility cycle of the building. BIM is a Methodology Building Information Modelling
