Transcript of buildingSMART BIM Training
BIM LEVEL 1 TRAINING WEBINAR LET US BEGIN WITH WHAT IS
NOT BIM! BIM (Building Information Modeling is not a 3D model!
BIM is not CAD!
BIM is not a software tool!
(Revit, Microstation, Archicad, Vectorworks, Tekla...etc) WHAT IS BIM? VARIOUS BIM DEFINITIONS EXIST OFFICIAL DEFINITION OF BIM The National Building Information Model Standard Project Committee defines BIM as:
Building Information Modeling (BIM) is a digital representation of physical and functional characteristics of a facility. A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle; defined as existing from earliest conception to demolition. The process of creating and using digital models for design, construction and/or operations of projects.
McGraw Hill, 2008, p. 2.
An object-oriented model — a digital representation of a building to facilitate exchange and interoperability of information in digital format.
Erabuild, 2008, p. 12. Inefficiencies of the Current Design and Documentation Systems Multiple Documents/Applications
Prone to Human Error
Labour Intensive Process
Costly and time consuming
Increased Liability Poor Interoperability processes and standards degrade value and accuracy of data passed between project partners!
Lack of Interoperability costs money!! $15.8 Billion Dollars in interoperability costs were quantified for the U.S Capital Facilities Supply Chain in 2002( by stakeholder group and Life Cycle Phase)
Operations and Maintenance Phase = $9.1 billion
Construction Phase = $4.1 Billion
Planning, Design and Engineering Phase = $2.6 Billion 30% of the cost of construction is wasted in the field due to: coordination errors
other problems in the current construction approach
(Report, “The Economist”, January 13, 2000) In conclusion
Buildings cost too much to build and operate! BIM helps achieve sustainability in Building Model Procurement BIM can help reduce the impact of construction and enables owners to make better informed decisions for urban planning, as well as transportation and utility networks. The statistics speak for themselves! Up to 40% elimination of un-budgeted change
Up to 80% reduction in time taken to generate a cost estimate
Cost estimation accuracy within 3%
A savings of up to 10% of the contract value through clash detections
Up to 7% reduction in project time
Stanford University Center for Integrated Facilities Engineering (CIFE) figures based on 32 major projects using BIM BIM TERMINOLOGY LITTLE BIM/CLOSED BIM BIM process and technology used within an organization Department, without regard for overall project data requirements.
Users don’t share BIM models/information with other stakeholders in the project. Information is transferred by using traditional file transfer methods.
Benefits of using BIM realized only by the user. Other stakeholders and the project do not benefit. OPEN BIM (BIG BIM) transparent approach that enables all stakeholders to be informed of project methodology, data and results without the need or obligation to use prescribed software.”
Project stakeholders are free in their choice of software. In practice this means using open BIM standards like IFC, BCF and others.

Smart Market report 2012 Increased performance &
profitability for construction companies LETS NOW EXPLORE THE BENEFITS FOR EACH CONSTRUCTION PARTY For Owners
For architects & engineers
For Sub-contractors & Fabricators HOW DOES BIM BENEFIT OWNERS? WHAT IS THE BENEFIT FOR ARCHITECTS AND ENGINEERS? BIM Impacts Conceptual Design
Multiple Assessment from a single Model are made possible:-
Circulation & Safety
BIM realises Real Time Feedback BIM FOR ARCHITECTS AND ENGINEERS BIM impacts Building System Design Integration with Analysis & Design Software
Multi Discipline Coordination
Automated Drawing Document
Production & Cost Estimation
Model based Code Checking
Simulation of operational Performance BIM FOR ARCHITECTS & ENGINEERS BIM impacts Construction Level Modeling Building Systems Layout
Drawing & Document Production from coordinated model
Design- Construction Integration
-Value Engineering as design proceeds
- Early setting of design constraints
- Identification of interaction between erection sequences
- Shortened cycle times for fabrication detailing
- Reduce coordination errors between systems WHAT IS THE BENEFIT OF BIM FOR CONTRACTORS? BIM presents multiple benefits for contractors Constructability Analysis
Quantity Takeoff & Cost Estimating
Construction Analysis & Planning
Integration with Cost & Schedule Control
Offsite FabricationVerification, guidance , Tracking of Construction Activities
Handover and Commissioning WHAT IS THE BENEFIT OF BIM FOR
SUB-CONTRACTORS & FABRICATORS Reduced Production Cycle Times
Reduced Design Coordination Errors
Lower Engineering & Detailing costs
Increased use of Automated Manufacturing Technologies
Increased Preassembly & Fabrication
Quality Control, Supply Chain Management, Lifecycle Maintenance BIM FOR CONTRACTORS WHY DOES THE CONSTRUCTION INDUSTRY NEED BIM? Lack of Interoperability in the construction process buildings are responsible for 50% of CO2 Emissions Lack of sustainability in construction WHAT ARE THE BENEFITS OF BIM? SmartMarket Report 2012
