Does it Work?Does it Work?

‘Given the trend of our age to eliminate the

craftsmen more and more, yet greater savings by

means of industrialisation can be foretold, though

in our country they may be, for the time being, still

appear to appear Utopian’

Walter Gropious, 1910

Fast paced changes in the Fast paced changes in the

Construction IndustryConstruction Industry

MMC ( and other forms of construction) are

effected by:

•Building Regulations

•Design codes

•Industry issues

Building RegulationsBuilding Regulations

Part A - Robustness, Progressive Collapse.

Solutions and products needed to meet the

requirements to compete with the more

traditional methods of construction.

For example the use of

engineered wood products

like LVL, and special

junction brackets.

Building RegulationsBuilding Regulations

Part E – Acoustics. Lightweight materials

need specific proven ways of reducing sound.

No reliance on density

Use of separating floors and walls, screeded

timber floors, acoustic battens etc

Building RegulationsBuilding Regulations

Part L changes - conservation of Fuel and

Power

Materials groups are looking for the

competitive edge without increasing other

building costs!

i.e. save energy at source, introduction of

insulation within frames, use of 140 studs

in open panels, SIPS and other closed

panel systems, passive ventilation central

stack and solar gain protection.

Design CodesDesign Codes

European Codes – new ways of structurally proving framing etc (

really?)

•Finnforest design software now in Eurocode >>>

•Century Kingspan product design are now based on Eurocode

Industry Wide IssuesIndustry Wide Issues

Green Building Guides – Eco Homes etc.

LPS2020 – insurance backed requirements to

prove MMC systems are durable

Labour / manpower shifts for UK to Eastern

European work force

Labour age groups, we have we lost the

ability to attract new thinking employees into

the Construction Market?

SO!SO!

We have the materials and designs for

Offsite construction to respond to market

changes but

There are still barriers and many still do not believe

MMC and Design ManagementMMC and Design Management

Success and failure based on communication and

defining roles within a project.

CCBe experience (including both success and

failure!) has led to a design process management

approach which considers design solutions and

options to match project drivers

Three basic phasesThree basic phases

• Concept

• Design

• Construction

ConceptConcept

•One size does not fit all!

•Different systems provide solutions to different

project issues

•Layouts – often considered to be identical but…

•Requires a team to review all aspects of the

process that an influence costs, build programme

and quality

•Team should include wherever possible the site

team / manufacturing team.

DesignDesign

•Should only begin when the concept of the

build process has been agreed

•Speed is not everything!

•Must make decisions to fix each design

stage, to fix the MMC elements.

•Beware conversion form one building format

to another!

ConstructionConstruction

•Design team to present principles of design

•Spell out how each design element will influence the

next trade to follow

•Failure in the management of trade packages stems

from a lack of understanding of the MMC used

•CCBe always undertake a meeting with the Client,

Contractor, Fabricator and other trades before the on

site start of each project.

SummarySummary

Success in MMC requires

• Understand and define roles and responsibilities

•Understanding of the full construction process not

just the factory produced parts

• Design team and client must understand that MMC is

not just a bolt on

• Review of all trade packages and their influence on

the build process

• The ability to make decisions early in the design

process and employ effective design process

management.
