Construction is € 2,6 trillion worldwide • 30% of construction has design correction costs • 40% of manpower used on construction sites is wasted • At least 10% of materials are wasted • Over 40% of projects are completed late or over budget, “ Rethinking Construction” by Sir John Egan – 1998 hundreds of billions € are wasted every year.

But… What is BIM? CONFERENCE : OCT. 14-16 | EXPO : OCT. 14-16 13 PALAZZO CONGRESSI VERONAFIERE | VERONA, ITALY
But … What is BIM? A REPRESENTATION of the Building, a DIGITAL Model? • It is a 2D or 3D virtual model of the Building • Intelligent model with a graphical representation An INFORMATION MANAGEMENT method? • A process usable throughout the life-cycle of the built environment with the aim to improve information exchange and analyses An intelligent building data-base? • Centralised information platform • Visualisation technique of all equipment, products and applied solutions CONFERENCE : OCT. 14-16 | EXPO : OCT. 14-16 14 PALAZZO CONGRESSI VERONAFIERE | VERONA, ITALY
But … What is BIM? A COLLABORATIVE project approach? Standardised format of data exchange Receive data from others, avoiding reintroducing data; Send your own data, with information automatically read by other players’ software Immediate analysis of the impact of design choices In Summary … BIM is : • Graphical representation of the building • A data-base of building components (features and behaviour) • A process of information exchange Where each component is treated as an object CONFERENCE : OCT. 14-16 | EXPO : OCT. 14-16 15 PALAZZO CONGRESSI VERONAFIERE | VERONA, ITALY
Operational Excellence with BIM CONFERENCE : OCT. 14-16 | EXPO : OCT. 14-16 16 PALAZZO CONGRESSI VERONAFIERE | VERONA, ITALY
Operational Excellence with BIM ‘every euro spent doing clash resolving during late design, the owner will save rework costs during construction.’ CONFERENCE : OCT. 14-16 | EXPO : OCT. 14-16 17 PALAZZO CONGRESSI VERONAFIERE | VERONA, ITALY
Operational Excellence with BIM • Facilitates passing from conceptual design to detailed design (vice- versa). • Facilitates master planning and neighborhood design Allows parametrising information blocks that conform to regulations, client expectations or certification requirements (LEED, HQE, BREEAM, ... ) CONFERENCE : OCT. 14-16 | EXPO : OCT. 14-16 18 PALAZZO CONGRESSI VERONAFIERE | VERONA, ITALY

The philosophy of integrating technologies with BIM • How to design, build, operate and maintain buildings to rapidly solve complex problems, based on accurate information and reliable analyses? • No longer “ why is reliable data important ?” but rather “ how can we collect and use data effectively ?”.
