firm’s name, are essentially
derived from
the beliefs and convictions of the firm’s
founder
, the engineer and philosopher, Ove

Today, Arup has a commanding presence
that is steadily expanding.
Arup’s strategy
of diversification across geographies and

means that the global
Arup has come a long way since the firm
was founded, yet we stay true to Ove Arup’s
original values.
Our unique trust ownership
structure means our people are free to
pursue the firm’s vision rather than chase
short-term shareholder returns.
This is how
we maintain our distinctive culture and
intellectual independence.

Building Information Modelling
is a
work
process
that incorporates
all
the aspects of the
building
in one
single virtual model.
BIM is a descriptive term
for technologically
advanced, collaborative and
information -
centric processes
in built environment design,
construction and operation.

Lifecycle Information Management
-
Communication errors and loss of project
information
-
25-30% of cost - splitting up processes/ bad
communication
-
Information is re-entered on average 7 times
before handover
-
Information is re-created several times by
different software
-
Design and construction is only a (small) part of
the lifecycle cost!
-
Errors are avoided
in the project by having the complete
documentation at your disposal
without interferences.
-
Errors are avoided in the
quantity surveying and
measurements
: complete and updated 3D model.
-
Contradictory pricing
caused by geometric errors in the
project drawing
are avoided.
-
Pre-payments are avoided by parties still not set up.
-
Cost of management
, maintenance and replacement of
equipment
is reduced
during the
lifetime
of the building.
-
It
improves productivity
and
management
in all phases.

BIM can contribute to these objectives
•
Tangible Benefits from BIM in projects:
Up to 40% elimination of unbudgeted change
Cost estimation accuracy within 3%
Up to 80% time reduction to generate a cost estimate
Up to 10% savings of contract value from clash detections
Up to 7% reduction in project time

BIM Impact
- BIM is mandatory in a number of countries for project above a certain size,
i.e. UK, Netherlands, Denmark, Singapore, parts of the States, Finland,
Norway.
- Other countries are considering a mandate, i.e. Germany, Australia.
- There is a EU-wide initiative for more collaboration with a strong lead from
the UK.
- In the UK the Government client group is responsible for ~ 40% of UK
construction procurement – changes in procurement system apply.
- Consistency of procurement across public sector clients.
- Contractual implications (liability, IPR, ownership).

Future, BIM and Industry
- Elements Tags
- The element ‘knows’ where it goes in the construction and it is linked with the construction program
- Can connect with construction monitoring tools - Can help with lifting setup
- The element embeds components which tell about the status or behavior of the element
Future, BIM e Industry
- BIM may help production optimization as in comes from project
- BIM provides information for formworks construction - Other industries work on BIM (cars, airplanes ect) - BIM may enable the Italian construction industry to
export its knowhow abroad
- Production camps may be thousands of kms away from the industry process is developed
Conclusione
- BIM si applica a tutti i settori del costruito e si propone come evoluzione moderna del processo di progettazione classico
- BIM porta alla industrializzazione del processo costruttivo
- Si evidenzia la nuova professionalità del BIM Manager come gestore del processo
- Altre professionalità cambieranno il loro rapporto con lo strumento informatico (ie ingegneri,
disegnatori ecc)
- Il progetto viene elaborato da tutto il team di progetto, viene consegnato in formato informatico
Conclusione
- BIM resta in vita per tutta la vita dell’edificio - BIM viene elaborato ed aggiornato dal
costruttore durante l’intero processo dell’appalto - Viene riconsegnato alla committenza quando la
costruzione è completata
- Gli strumenti, metodi e processi aiutano, ma nel nostro settore quel che conta sono sempre le idee associate alla conoscenza
- BIM deve essere considerato come via di comunicazione tra tutto il team, i progettisti, il cliente, l’impresa e l’utilizzatore dell’edificio - Il processo di integrazione di BIM, come metodo
di processo nel mondo del costruito, è irreversibile
