Why BIM?3

We live in a 3D data rich world

Why not design in this environment?

Begin with the End in Mind

From This . . .4

To This

BIM is a 5

Sociotechnical System

• People

• Process

• Technology

BIM6

People

• Top down approach

• Identify BIM Champions

• Training l Skills Matrix

• BIM Buddies for new learners

• Frequent and meaningful communication

• Environment must be collaborative, not combative

BIM7

Process

• Project BIM Execution Plan

• Project BIM Strategy

• Process Maps

• Standards

• Protocols

BIM8

Technology

• Which Hardware?

• Which Software?

• Any client specific requirements?

• Software must be fit for purpose!

Project BIM Strategy10

BEGIN WITH THE END IN MINDClient wants BIM!

Project BIM goals?

All parties providing a BIM?

What will model be used for?

Level of development (LOD) matrix

Model definition section to expand on LOD Matrix

BIM scope document BEFORE contract award (EIR) (Employers Information Requirements)

Level of Development (LOD)12

LOD 100 The model consists of overall building massing indicative of area, height, etc., etc.

LOD 200The model consists of generalised systems or assemblies with approximate quantities, size, shape, location and orientation.

LOD 300The model consists of specific assemblies accurate in terms of quantity, size, shape, location and orientation.

LOD 400This level of development is considered to be suitable for fabrication and assembly.

LOD 500As Built conditions

Focus on Critical Areas in Early Stages13

Primary Plant Rooms

Primary Riser Shafts

Typical Corridor Sections

Building Services Pinch points

This approach limits exposure to rework and elements most likely to change from DD onwards.

BIM & MEP are made for each other!14

• Game Changer for coordination

• Huge benefits in proving spatial requirements

• Forces designers to think more thoroughly (Constructability, Accessibility etc.)

• Use the ‘I’ in BIM to advantage (Equipment schedules, Conditional Formatting etc.)

Considerations15

How to split models?

To Host or not to Host? Can we control others model approach?

What to model as 3D? What to model as 2D? What not to model at all?

Design BIM v Construction BIM

BIM Process is the Key16

• Regular workshops and valuable communication / collaboration

• No more Silos!

• Modelling strategy is KEY

• Agree project strategy BEFORE modelling

• Clash avoidance, not clash detection

• Clash Resolution Strategy

Lessons Learned17

It’s a team effort

Focus on value BIM brings to project

Plan Ahead and Stick to the Plan!

Persevere and you will succeed

Embrace BIM, Don't Fight it

Summary18

Begin With The End In Mind

BIM is Very Powerful

With Great Power Comes Great Responsibility!
