LBH LCP - What is BIM?
Transcript of LBH LCP - What is BIM?
From the BIM Industry Working Group – March 2011 Frankham Consultancy Group BIM
"As multi-disciplinary design consultants, we acknowledge the BIM processes and technologies aid the construction process from early conception through to project completion and beyond. BIM can be used as a tool to improve the process of the lifecycle of a project therefore enhancing the information to all people utilising it. It is not only a replacement for CAD, as it requires a change in mindset for all team members’ knowledge and processes as well as the technology they use." What are the benefits of using BIM? Inputs and Outputs - What do you do with the information? The BIM Process Map What is 3D,4D & 5D BIM Modelling? Technologies - BIM integrated software and hardware
3D Modeling Who are you employing? A Building Information Model is a rich information model, consisting of potentially multiple data sources, elements of which can be shared across all stakeholders and be maintained across the life of a building from inception to recycling (cradle to cradle).
The information model can include contract and specification properties, personnel, programming, quantities, cost, spaces and geometry. - NBS BIM – 2010 Reduction in scope for contract growth
Improved co-ordination between disciplines
Pre construction clash detection and review
Improved design processes to reduce on design iteration
Streamlined drawing processes
Enhanced level of information eliminating design ambiguity
Reduction in Abortive work and data re-entry
Superior auditing tools and error checking interfaces
Co-ordinated 3D model and information INPUTS OUTPUTS Existing Site/Project Information
BIM Execution Plan
Funding Approval Virtual Prototype - 3D model
3D Visualisation Imagery
Data Interrogation and extraction
Facilities Management Information
Asset Management Information
Life Cycle Analysis
COBie Autodesk Revit - BIM software Platform (Multi discipline) PRACTICAL ISSUES BIM still in development. The industry is at different stages and moving at different speeds
BIM can be used in different ways
It requires new and different ways of working
Software is not always compatible
Investment costs can be significant
Introduces new roles eg the Information Manager LEGAL/CONTRACTUAL ISSUES IMPLICATIONS FOR PROCUREMENT AND SUPPLY CHAIN RELATIONSHIPS WHAT IS BIM? “2.32 Government will require fully collaborative BIM level 2 (with all project and asset information, documentation and data being electronic) as a minimum by 2016.” Strategy Paper for the Government Construction Client Group From the BIM Industry Working Group MARCH 2011 "Government advised to mandate BIM on all central projects in excess of £50m." KEY MILESTONES: A report for the Government Construction Client Group. One Year On Report and Action Plan Update JULY 2012 Project Delivery and Better Information Copyright & IP
Should not be a barrier to BIM adoption
Contracts - are pre BIM but can be simply amended
BIM Protocols for project delivery & outputs
Define new BIM roles & responsibilities
Clarify risk transfer Consultant-Contractor-Client
Insurance & liability
Consider insurance to support BIM collaborative working Faster Quantity Take-offs
API - Construction rather than Design Object Quantities
More detailed & accurate cost estimates
Reuse cost data on future projects
Clarity of design HOW DO YOU USE BIM?
Other than a digital-tool set you don’t actually use BIM, it is way of working, it’s what you do: information modeling and information management in a team environment.
The rich 3D experience; digital simulations; rehearsals of all stages of the design, build and operate process; and the information within the models facilitate well informed decision making resulting in better business outcomes, clarity, improved communication, removing risk and ultimately better efficiency. Point cloud surveying and modelling Benefits to 4D & 5D Modelling Information
Focus on value adding: not removal
Visual record of measurement/programme
Early & improved value engineering
Schedule simulation The Autodesk

Peripheral BIM Management & Interrogation Tools for 3D, 4D and 5D Modeling Revit Architecture Revit MEP Technologies - BIM integrated software and hardware Augmented reality Printed models Level 0 - Unmanaged CAD, 2D Drawing and simple data exchange (email)
Level 1 - Managed CAD, 2D and 3D utilising collaboration software. Data Management tools with limited integration.
Level 2 - Managed 3D environment including BIM tools and group file collaboration. 4D and 5D modeling
Level 3 - Fully integrated and enabled 'cloud or web' services compliant with IFC/IFD standards managed on a collaboration server. iBIM and Life cycle modeling for projects. BIM MATURITY LEVELS Projected Project Input Curve Beware the BIMwash! BIM(M) is a managed approach to the collection and exploitation of information across a project.
At its heart is a computer-generated model containing all graphical and tabular information about the design, construction and operation of the asset. COBie is an information exchange specification for the life-cycle capture and delivery of information needed by facility managers. COBie can be viewed in design, construction, and maintenance software as well as in simple spreadsheets. This versatility allows COBie to be used all projects regardless of size and technological sophistication.
