1.
2. Aims Promote collaborative working
Support the supply chain through facilitation, training and resource
Innovation in partnership with industry
Independence and impartiality
Evidence based design, delivery and operation
Services Research and Development, Education, Consultancy
4. What is BIM ?
“An integrated digital process providing coordinated, reliable
information about a project throughout all phases, from design through
construction and into operation”

5. BIM is not 3D CAD
BIM is not a single building model
BIM is not a single software technology
BIM is not a replacement for good communication, team working and
due diligence
What BIM is not
13. “Government will require fully collaborative BIM (with all project
and asset information, documentation and data being electronic) as
a minimum by 2016. A staged plan will be published with mandated
milestones showing measurable progress at the end of each year”
Why adopt BIM ?
14. Why adopt BIM ?
Adoption of ‘Push-Pull’ strategy
Leave complexity and
competition in the supply chain
Be specific with supply chain
on requirements
Measuring and active use of
outputs
Support infrastructure
Progressive steps
Target for ‘trailing edge’ of the
industry
16. Improved design reliability Reduced design risk Reduced waste
More time to get the design right Enhanced coordination and fewer
errors Improved decision making Greater productivity Higher quality
of work Downstream uses for FM Supports sustainability Improved
safety Computation of material quantities Improved planning, control,
management of construction Enhanced communication Effective
resource utilisation and coordination of activities Reduction in costs
associated with planning, design and construction Reduced number
of RFIs Improved collective understanding of design intent Less time
documenting more time designing Quantity takeoff Client
engagement Improved spatial coordination Programme reduction
Offsite prefabrication with confidence
Why adopt BIM ?

Quality Management Responsibilities
Project Phases
20. Laser Scanning
Point Cloud output of laser scanning
Use of high definition scanning equipment
Captures millions of survey points (3D)
Provides accurate as-built information
Interoperable with BIM tools
Used as basis for design development
Validates accuracy of existing model
25. Pedestrian Simulation
Crowd simulation and analysis
Real time calculations and display of agent flow
Interoperability with BIM tools
Programming of individual personalities
Automatic validation of results
Design analysis and testing
Feedback: journey timings, flow rates, queue sizes
Highlight bottlenecks in design
38. COBie2 standard
3D models can be exported to FM software
More effective tracking and management of assets
Improved operational efficiency
Tool for strategic decision making
Improved information sharing across business
Ease of reporting
Visualisation of facilities and infrastructure
Model-based facilities management (6D)
