Responding to Barker 33

Barriers and Solutionsto the use of

Modern Methods of Construction

Ashley Lane, Chairman Barker 33 Cross-Industry Group

Barker 33 recommendation

“The HBF, in conjunction with NHBC, Construction Skills and other interested parties, should develop a strategy to address barriers to Modern Methods of Construction (MMC). This strategy should be developed to fit alongside existing initiatives, working closely with Government to identify further measures that can be taken. A range of approaches should be explored, in particular actions by industry, plus changes to policy / practice, as well as representations to Government on areas such as Building Regulations.”

In October 2004 a Cross-Industry Group

was established to address the remit

The Group prepared 3 reports:

1st interim in November 2004

2nd interim in April 2005

Final Report, December 2005

The 1st report identified the following barriers:

1. Lack of understanding2. Lack of confidence/ process change3. Cost perception4. Lack of positive track record to date5. Lack of agreement on product and process

standards6. Traditional process management7. Design bias8. Supply chain immaturity9. Lack of skills10. Turning MMC from a requirement to a 'want'

The 2nd report identified action in the following areas:

        The need to improve understanding of MMC        Definition of MMC as wider than product

innovation        Recognition that MMC was often a process-

pull not product-push mechanism for innovation        The heightened process discipline required

by MMC         The need to develop skills and professional

training in the context of MMC         The enabling of MMC by matching the regulatory

environment to the business environment        Improvements in the understanding of MMC

costs and benefits

The Final report considers the business context and definition of MMC and outlines a number of actions to be taken to address the barriers to adoption of MMC

Business contextThe Barker 33 Group saw the business context as being well beyond a product-based system.

MMC embraces:

• Greater business efficiency• Enhanced design and quality• Improved customer satisfaction• Enhanced building performance• Increased housing supply meeting the

aspirations of the market as a whole (open market, social and affordable)

• Enhanced environmental performance with reduced impact

Definition of MMC

Modern Methods of Construction are about better products and processes. They aim to improve business efficiency, quality, customer satisfaction, environmental performance, sustainability and the predictability of delivery timescales.

 Modern Methods of Construction are, therefore, more broadly based than a particular focus on product. They engage people to seek improvement, through better processes, in the delivery and performance of construction.

MMC – building homes people want

Work of the Barker 33 group and NAO

The Barker 33 Group has coordinated and integrated its work with that of the NAO which has been examining MMC and has recently published its report ‘Using Modern Methods of Construction to build homes more quickly and efficiently’.

The NAO study has

• Examined construction process and process efficiency for a typical small development by an RSL

• Established generic process maps for a number of systems (including brick and block, frame and volumetric products)

• Compared labour requirements for on- and off-site process

• Examined costs for a number of product-based MMC systems in comparison with brick and block

• Exposed the importance of process and regulation integration necessary to achieve maximum efficiency gains and cost reductions

NAO on-site labour comparisons with brick and block

Major Barker 33 Group and NAO findings

• Recognise that MMC can be cost-competitive

• Understand that savings in process efficiency can put costs of MMC on a par with traditional construction

• Appreciate that process and product improvement are the core mechanisms for cost reduction

Uptake of MMC in housebuilding

• 150,000 dwellings built In 2004

• 17,000 built in MMC

• Approximately 12% of new build

• Similar proportion to Germany

• Approximately 150 UK product suppliers

• Stimulation from EP and HC

• Major players include Barratt, Redrow and Persimmon/Westbury

• More entering the market

Business case for MMC

• Cost: cost competitive

• Time: 20-60% faster

• Quality: 50% defect reduction

• Waste: 50% reduction in skips

Additional measures could be -

environmental performance, delivery certainty

and customer satisfaction

MMC case study

Westbury Partnerships/Persimmon Homes

• Building on the positive business benefits of MMC

• Largest UK residential developer

• Building sustainable communities with MMC

• 2,500 homes built in 2005 incorporating Space4

• Target to increase this over next few years
