Definition of BIM…


– It is the digital representation of the physical and functional characteristics of a built facility creating a shared knowledge resource for the information about the building and forming a reliable basis for decisions during its lifecycle, from earliest conception to demolition. • RIBA definition

– A digital representation of physical and functional characteristics of an asset in the built environment, and a shared knowledge resource , gfor information about that asset forming a reliable basis for decisions during its life-cycle; defined as existing from earliest conception to demolition. • AECOM definition


• Building Information Modelling should be considered in the context of a verb and not a noun,

“building an information model”, the process of generating and i j t d t th h t th lif l f t T i llmanaging project data throughout the lifecycle of an asset. Typically

utilises 3D, real-time, dynamic modelling software to capture and reuse critical project data. Building Information Modelling solutions have th h t i tithree characteristics:

– they create and operate on digital databases for collaboration– they manage change throughout those databases so that change to any part of the

database is coordinated in all other parts (parametric)– they capture and preserve information for reuse by other members of the AEC value

chainchain.


• BIM or BIMM?

• Building– The built environment– The built environment

• InformationA d t th t l t t th b ilt i t– Any data that relates to the built environment

• Modelling– 2D, 3D, 4D, 5D, 6D ,nD, spreadsheet, database etc……

• ManagementManagement– Process & workflow that facilitates intelligently sharing and reusing

information to design, document and deliver


• A methodology to exchange and reuse informationgy g– Share more information– Reuse more information

T k hi f i f ti– Take ownership of information

• An enabler– A better way to communicate design intent– A way to bring disparate design teams together

An aid to risk management– An aid to risk management

• A process to Design, Document and Deliver (the 3 D’s)– The right Information– To the right People– At the right TimeAt the right Time


• Not a single software solutiong

• Not a single vendor solution

• Not just CAD

• Not just 3DNot just 3D

• Not a short term cost saving solution

• Not the answer to everything


• Drivers for BIM • Benefits– Client requirements– Govenment

I d t i iti ti

– Greater client satisfaction– Improved communication

I t t d kfl– Industry initiatives

• Adopters

– Integrated workflow

• Barriers– Open book approach– Early involvement

Mutual trust and respect

– Resistance to change– Lack of trust

Traditional contracts– Mutual trust and respect– New contractual agreements

– Traditional contracts– Internal procedures– Cost / training / skillsg

• Level 0– Unmanaged information, 2D (electronic or paper)

• Level 1Level 1– Managed information, 2D / 3D, possibly using BS 1192:2007– Standalone, silo discipline information, possibly shared using an

extranet system (common data environment), file based

• Level 2– Managed information, 3D discipline information models– 4D, 5D integrated shared information, file based

• Level 3– Fully open system, web hosted (cloud service), totally integrated

Cbased upon emerging standards, IFC, IDM, component based

Process…

• The message from government is that information is the g gkey to success of meeting the construction strategy objectives

• The right information at the right time and to the right level of detail to enable consistent, informed decision making by the government client across all departments

Process…

• Help the Design and Construction team to drive out waste but all the time protecting (or even increasing) profittime protecting (or even increasing) profit

• Refocus on sub contractors and supply chain efficiencies and profit levels (Market test with subcontractors)( )

• Identify the potential project risks and provide value management advice

• Advise contractual / commercial / liability issues

• Use BIM models to create Benchmarking Data and create rates for future cost modelling

• The future holds greater accuracy and certainty of outputs

• However BIM will never replace the market. The Cost manager will still need to interpret the market when advising on the cost of building.

Process…

• Collectively develop a project processy p p j p– Understand expectations– Align software / technology to enable BIM

D fi l & ibiliti– Define roles & responsibilities– Define standards– Share informationShare information– Reuse information– Communicate

• Start the conversation as early as possible
