Demands on Construction
Nowadays, construction can no longer get by through just delivering the traditional requirements of: Cost Quality Timeliness
Both legislation and society demand a more progressive approach that integrates construction activities with current social trends, such as: Urban regeneration Low carbon approaches in design, construction and building management
In other words, sustainability has become an integral part of the construction process
Sustainability in Construction
A partial list of the legal requirements includes: Health and Safety at Work Act Duty of Care Control of Substances Hazardous to
Health Construction (Design and
Management) Site Waste Management Plans
The list on the right showed the type of activities we also need to take into account – many are beyond legislative requirements
Construction: Facts, Myths and Realities
Fact: Design is paramount with superstar architects creating impossibly beautiful and carbon efficient buildings
Fact: the UK construction industry is concerned about the skills of its workforce
Myth: what you see in architect’s design graphics where the buildings all look shiny with happy people (in ethnically and socially correct ratios)
Myth: the fantastic buildings all work as designed
Reality: fantastic designs are often “revised” through value engineering to cut costs
Reality: plans and drawings are often changed to make them “build-able”
The Construction Process (simplified…)

Reality Check at the Construction Site
One of the major issues with construction is the level of materials waste
The UK disposes of about 100M tonnes of construction waste each year
Anecdotally, this is about 1 pallet in every 5 delivered to a project site
By dealing with waste effectively, we can bring about sustainability
Cutting Waste in Construction
Using Lean tools to: Design out wasteful process Reduce waste by solving
problems Enable better “Reuse” by more
effective workplace organisation
Recycle more efficiently by better segregation of waste
Minimise amounts to landfill
Bovis Lend Lease: 2 Paths to Sustainability
Specialists and professional sustainability and environment managers deal with various compliance and auditing duties
Provide advice to project managers and teams on what needs to be done
Make sure the necessary training is available
Engage the workforce Make sure the people doing
the work know what is critical to the success of the project
Tap into the workforce’s experience, skills, knowledge and decision-making to cut waste
Introducing
The NoWaste programme is a site-based lean and sustainable construction programme aimed at construction teams, not specialists
Uses lean and six sigma tools to help teams come up with practical solutions to waste issues
Deployed successfully since 2004 at various Bovis Lend Lease projects: 2005 National Green Apple Award winner 2006 Building Magazine Sustainability Award: Waste Initiative of the Year 2007 Construction News reported that NoWaste reduced 25% of site waste 2009 “Most Effective Training” award Olympic Park & Athletes Village
Specifics
Aimed at the construction operatives and supervisors
Takes a construction-site centric approach about construction and waste issues
Looks at issues as the workers see them
Delivered via a cartoon interface…
And Lean / Six Sigma
Lean issues are embedded into the training materials and with no jargon Specific techniques are designed such that they became part of the route
towards solving problems Best demonstrated by the product
The teams are shown a graphic describing a waste situation and they are then guided to associate this with their own work and solve problems
Tools deployed: DMAIC – Six Sigma Quality Fish Bone (Cause/Effect) analysis – Lean Asking Why? (Root Cause) analysis - Lean
Results
Saving Money, Reducing Environmental Impacts £136K over 3 months in waste
disposal costs only (2010)
Motivating People Over 400 people trained (2010) Achieving over 50 NVQ awards
Is Lean Mean?
The alternative to cutting waste is to damage the UK’s economy and its environment
It is much “meaner” to pay that price
Lean may be tough to do, but it is also the right thing to do
