4. The importance of pre-assembly
ALAN CRANE
Chairman
Rethinking Construction

5. Why Rethink Construction ?
£70 billion turnover - 10% of GDP 
Employs 1.7 million 
Low profitability  
Low levels of investment 
High client dissatisfaction
Substantial under-achievement 

6. ‘Rethinking Construction’
The Report:
- Commissioned by the Government
The Scope:
- For improving the quality and efficiency of UK construction
The Task Force:
- Led by Sir John Egan included only people from other industries

7. ‘Rethinking Construction’
Based its recommendations on tried and tested methods from other industries
Set out a model for change and improvement

9. Rethinking Construction objectives
Promote innovation for Performance Improvement
In Business Process
In Procurement
In People – through Respect
In the Product & Components
PROVE the CASE & CHANGE THE CULTURE!

10. PERFORMANCE IMPROVEMENT
Value, not Cost-
“It is not cheaper things that we want to possess but expensive things that cost a lot less”
Measurement –
If you do not know where you are, how will you get where you want to be?

11. PERFORMANCE IMPROVEMENT
THE TARGETS
An Efficient & Effective Industry
Predictable- Time
Cost
Quality
Health, Safety and Respect for People
ALL PROVIDED BY STANDARDISATION & PRE-ASSEMBLY

12. STANDARDISATION IS NOT IS A Panacea for industry problems
A restraint on Design IS
The use of Tried, Tested and Proven
The right fit & Fit First Time
An opportunity for customisation & flair- without the risk!

13. PRE-ASSEMBLY
IS, CAN BE
MODULAR
VOLUMETRIC
NON-VOLUMETRIC (Precast, frames etc)
COMPONENT MANUFACTURE & SUB-ASSEMBLY
Off site Construction in controlled conditions for On site installation- without the risks!

14. RETHINKING CONSTRUCTION has the evidence
DEMONSTRATION PROJECTS in the last 3 years…
Represent 3% of industry output
Have killed ZERO people- rather than 8
Have reportable accidents 70% lower than official industry rate – and 15% of real rate
YET

15. RETHINKING CONSTRUCTION has proven performance
30% better on Time and Cost predictability
32% better on Quality
29% higher productivity
33% higher Client satisfaction
And 35% higher profitability

16. COINCIDENCE?
THAT
Projects efficiently managed by committed, well educated & trained challenging people working together achieve better business performance
Better business performance provides a happier, healthier, safer and more satisfying workplace

17. RETHINKING CONSTRUCTION has proven performance
Based on Demonstration
Based on collaborative, clustering integrated teams attempting innovation
But it needs to become the norm
Simple tools for Simple People
Available Now- IMMPREST

18. Measuring benefit helps to overcome barriers.
What is IMMPREST?
Interactive Model for Measurement of PRE-assembly and STandardisation benefit in construction.
Measuring benefit helps to overcome barriers.

19. IMMPREST overview Comprises 3 “tools”:
Toolkit A is information & background
Toolkit B operates at project strategy level focusing on the project drivers
Toolkit C provides detailed elemental evaluation of benefit

20. Benefits classified as:
Cost
Time
Quality
Issues that are relatively well understood
Health and Safety
Sustainability
Benefits from site activities
Softer issues, often overlooked in evaluations.

21. IMMPREST outputs
A structured investigation of pertinent aspects of a project – definition of project drivers
What if..? simulations allowing comparison of alternatives.
Risks are highlighted as are benefits along with what to do or not do
The route taken to reach a decision is auditable
Printed reports are available at every stage

22. Who can use IMMPREST?
Its main use is for evaluating design options principally by cost consultants
Manufacturers will find it useful for marketing
Project managers/contractors can use the outputs to assist risk management and site constraints
Planners can use outputs to identify critical activities

23. Other uses
The need to define project drivers encourages a team approach to the project strategy
The more the toolkit is used, the greater the potential to develop a comprehensive data base.
The structured framework requires a more considered approach to knowledge management

24. IMMPREST does not give you THE answer (not appropriate or desirable for software to do this) It helps the team develop the best answer

25. Clients, industry and government working together to improve UK construction

26. Generally
IMMPREST builds on earlier work and links closely to related research
This forms an integrated effort to achieve real uptake of pre-assembly
