-20% -40%

“Rethinking Construction” by Sir John Egan - 1998. •  30% of construction is rework •  40% of the manpower used on construction sites can be wasted •  At least 10% materials are wasted •  Over 40% of projects are completed late or over budget.

Waste in the Construction Industry

The cost of inadequate interoperability in the U.S. capital facilities industry estimated at: $15.8 billion per year

Duplication of Work

Ø  Improvement in quality Ø  Reduction in production time Ø  Reduction in cost

Waste & Inefficiency can be attributed to

Ø  Overproduction Ø  Waiting Ø  Transportation Ø  Processing Itself Ø  Stock at Hand Ø  Movement Ø  Making Defective Products

Lean Manufacturing Primary focus is the elimination of waste & inefficiency

Digital & BIM in Total Architecture

“The term ‘Total Architecture’ implies that all relevant design decisions have been considered together and have been integrated into a whole by a well organised team empowered to fix priori=es”

Sir Ove Arup – The Key Speech -‐ 1970

“This is an ideal which can never – or only very rarely – be fully realised in prac=se, but which is well worth, for striving for ar=s=c wholeness or excellence depends on it, and for our own sake we need the s=mula=on produced by excellence”

“This is an ideal which can never – or only very rarely – be fully realised in prac=se, but which is well worth
