ty Overview

What’s BIM?

BS ISO 29481-1 2010 - Building information modelling -

Information delivery manual

“Shared digital representation of physical and functional characteristics of any

built object (including buildings, bridges, roads, etc.) which forms a reliable basis

for decisions”

BIM Definitions

CPIC /RIBA – Proposed Definition

“Building Information Modelling is digital representation of physical and

functional characteristics of a facility creating a shared knowledge resource

for information about it forming a reliable basis for decisions during its life

cycle, from earliest conception to demolition.”

What’s BIM?

BIM – A Change to Process

”MacLeamy Curve” Patrick MacLeamy , CEO, HOK

“The number of construction professionals using bim (building information modelling) has

jumped from 13% to 31%, according to the results of the NBS’s annual bim survey.

Of the 1,000 respondents to the national survey, almost 19 out of 20 expected

to be using bim within the next five years;

80% of those who had already adopted bim agreed that it increases the coordination of

construction documents; while 65% said it delivered cost efficiencies.

Why BIM?

Bim adoption more than doubles

8 February 2012

• 2D communication in a 3D world

• Traditional problems

• Sustainable design and energy performance compliance

• Building performance regulation

• Waste within construction

• Latham / Eagan Reports

• Best practice

Why BIM?

Government Construction Strategy

• 20% reduction in costs targeted for UK construction

procurement

• BIM confirmed as an essential element in the reduction

waste within construction.

• BIM working party strategy published June 2011.

• Begin phased roll out to all government projects from

summer 2012

• Introduction of Construction Operations Building

Information Exchange (COBie 2.4)

• All UK public funded construction projects will require

fully collaborative 3D BIM (level2) as a minimum by

2016.

BIM Levels

BIM Technology – ArchitectureBIM technology is being developed by a range of major CAD vendors

but is represented by three main staples for Architecture;

Revit Suite

NavisWorks

Grahisoft Archicad

Vecterworks

All-Plan

Microstation

Bentley Architecture Many More BIM packages for

Environmental and Structural

analysis

BIM Awareness

Government has given BIM a big boost, but;

• Currently still Confusion

• BIM seen as an obstacle not an enabler

• We are adapting BIM to fit current practices

• ‘My’ BIM

• Varied Adoption

• Software collaboration needs to Improve

• Definition of BIM is not important it is about understanding what BIM

Enabled Technology can do for you.

• We need to understand BIM Better

BIM -Currently

BIM Definition

Chuck Eastman, The BIM Handbook

…“an intelligent simulation of architecture.” To enable us to achieve integrated

delivery“

BIM alone fails to achieve Level 3 objectives.

Only when we have a proper working understanding of BIM will we be able to

begin the next step of integrated BIM (iBIM) and Integrated Project Delivery (IPD)

iBIM / Integrated Project Delivery (BIM Level 3)

• Only Suitable for Large projects?

• Just 3D CAD?

• Can’t Do refurbishment?

• Costs too much?

• Takes too long?

• Doesn't Suit Our Process?

BIM POSSIBLE?

Project Examples – Oldham BSF

Oldham BSF: North Chadderton School & Sixth Form

Contractor: Balfour Beatty

Value : £20m

Consultants:

Clarke Bond (SE)

RPS Group (M&E)

Arup (Fire)

Advantages

• BIM Implementation project

• Single source of information – Co-ordination

• Ability to adapt design during all stages

• Able to produce drawn information quickly

• Automated schedule / take off

• Worksharing environment

• Contractor using BIM for Co-ordination

Disadvantages

• Consultants were not using BIM

• Software learning curves for design team.


Advantages – 3D Environment & Rendering


Project Examples – Kearsley Academy

Contractor : BAM

Value: circa £10m



• Grade 2 Listed

• Refurbishment & Extension

• ty+ Rombol (Gifford)

• Lonely BIM(s)

Proposed Image (3Ds Max)

Existing MarketRevit Model View

Project Examples – Chesterfield Market

Project Examples – Housing Team

• Planning Implementation Is key

• Develop a sound, comprehensive implementation strategy,

• Assemble the right team,

• Select a suitable starting project

• Understand the learning curves

• Understand Cost and Benefits to business

• ROI –calculators

• Hardware requirements

BIM – Implementation

• Improve design quality

• Improve communication

• Single source of Information

• Increased collaboration with partners

• Reduction in waste

• Opportunities for re-use of data post construction

Summery- Why use BIM?

The introduction of BIM is not about the adoption of any software; it is probably

the most significant change process you will ever make

Conclusions

• Industry is developing clear best practice with BIM

• More Open about current BIM adoption.

• BIM definition is not important it is about understanding the benefits of a

BIM Environment

• Once we are BIM enabled then we can move to Social and iBIM

• Working procedures need to adapt to enable iBIM/IPD

• Real risk that not having BIM experience could exclude you from future

projects

Questions?

Darlington top 5

• How will BIM effect construction SME’s ?

• What support can the government offer SME’s (training and education

being a priority)

• What software tools are appropriate for BIM in a contracting environment?

• Will all sub-contractors to the main contractor be expected to use BIM

tools? If they don’t have them – how will the main contractor share

information?

• What is the cost of up-skilling and ‘tooling up’ in readiness for BIM?

• How quickly will businesses see a return?
