Rethinking Construction

Why Rethink Construction ?

£70 billion turnover - 10% of GDP

Employs 1.7 million

Low profitability

Substantial under-achievement

Low levels of investment

High client dissatisfaction

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

‘Rethinking Construction’

Based its recommendations on tried and tested methods from other industries

Set out a model for change and improvement

‘Rethinking Construction’ – a summary!

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!

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?

PERFORMANCE IMPROVEMENT

THE TARGETS

An Efficient & Effective Industry

Predictable- TimeCostQuality

Health, Safety and Respect for People

ALL PROVIDED BY STANDARDISATION & PRE-ASSEMBLY

STANDARDISATION

IS NOT

A Panacea for industry problemsA 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!

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!

RETHINKING CONSTRUCTIONhas 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

RETHINKING CONSTRUCTIONhas proven performance

30% better on Time and Cost predictability

32% better on Quality

29% higher productivity

33% higher Client satisfaction

And 35% higher profitability

COINCIDENCE?

THAT Projects efficiently managed by

committed, well educated & trained challenging people working together achieve better business performance

THAT Better business performance provides a

happier, healthier, safer and more satisfying workplace

RETHINKING CONSTRUCTIONhas 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

What is IMMPREST?

Interactive Model for Measurement of PRE-assembly and STandardisation benefit in

construction.

Measuring benefit helps to overcome barriers.

IMMPREST overviewComprises 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

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.

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

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

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

IMMPREST does not give you THE answer

(not appropriate or desirable for

software to do this)

It helps the team develop the best

answer

Clients, industry and government working together to improve UK

construction

Generally

• IMMPREST builds on earlier work and links closely to related research

• This forms an integrated effort to achieve real uptake of pre-assembly
