Presentation Contents What is BIM? The Outputs The Process The Opportunities
What is BIM The Designer
Building Information Modelling BIM Mott MacDonald s definition: BIM - a coordinated set of processes, supported by technology, that add value through creating managing and sharing the properties of an asset throughout its lifecycle
The Benefits of BIM
BIM is for the whole lifecycle BIM Model Source: Autodesk
BIM for the built environment Road Map
What Is BIM The Outputs
Multi-disciplinary co-ordination

Design The Process
The Design Funnel A need - A site An idea Some Constraints A design
Which Way Do We turn?
To Deploy BIM it is Both: A Noun and a Verb It is both a virtual object and a process For BIM to work as a process, interoperability is key (Data push/pull)
Structural Engineering Structure is Easy Isn t it? Lots of similar elements repeated many times

The MEP Step Change - Early Analysis Bringing analysis into conceptual stages of design. Visual Impact Solar Position Overshadowing To consider all aspects of building performance. Vasari/Ecotect or something else? Shading Optimization Solar Availability Incident Radiation Shading Design Envelope Design Daylight Analysis Thermal Performance Acoustic Design Rights-to-Light
Building Energy Performance MEP Volumes and demands on those volumes
Where does stuff go Lighting Analysis
Schedule Counting things again
Which Way Do We turn? 9 variables 1.2 million solutions Building form various 6 Orientation 35 through 60 degrees north 25 Roof overhang depths per facade 6 Glazing ratio 25% 28% 30% 3 Glazing G values 3 Daylight none daylight linked glare and daylight 3 Structure Steel Concrete (Mass) 2 Building Fabric U Value performance combinations 5 Window Construction performance combinations 5 1215000 Cost /Time? Embodied Energy?
Embodied Energy as a Variable
Which Way Do We turn? Building Design/Project Quality. Optimise Energy Consumption, Optimise Space, Optimise Equipment Size, Optimise Embodied Energy, Optimise Cost, Scheduling, Optimise Build time, Optimise building operation, Optimise beauty? Arrchitecture
The outputs The Opportunities
Anglian Water product based delivery BIM hugely facilitates offsite manufacture
Anglian Water product based delivery 90% Time saving 20% Less Carbon
Optimisation The Challenge
Optimisation The Ultimate
