What have we changed (Lean)

Encouraged Standardisation and repetition Maximised off site manufacture Reduced Waste in all forms by reducing and eliminating operations Standardised timber frame design and minimise design costs Standardise teams for • Client • Contractor • Designers • Subcontractors • Supplier Improved familiarity and co-operation between teams and supply chain with products Allocated ownership to problems and issues and visually monitor the resolution Prioritised early spend on critical issues/risks Trialled different construction techniques

What are the Benefits?

Highly Insulated efficient buildings U valves 50% improved Air tightness results of 3.5

25% fewer deliveries to site 50% fewer movements on site vehicles Recycled materials/waste – 89% Significant noise level reductions 60% reduction in building waste Confidence in cost and programme – known outturn costs 9 week Lean target Programme on Current Scheme 33 Units erected in 7 weeks Quality and predictability is increased Non productive costs are significantly reduced Weather dependency significantly reduced Reduced Utility Bills for occupants
