3 Arup

4 We are an independent firm of planners, engineers, designers, consultants and technical specialists, offering a broad range of professional services around the built environment.

5 Arup s creative spark and intellectual independence has been there from the very beginning. These shared values, like the firm s name, are essentially derived from the beliefs and convictions of the firm s founder, the engineer and philosopher, Ove Arup.

6 Ove Arup

7 We are truly global. From more than 90 offices worldwide our 12,000 planners, designers, engineers and consultants deliver innovative projects around the globe.

8 Who we are 12,000 staff 90 offices 35 countries

9 We are still growing. From modest beginnings in 1946, today we are a 1 billion per year turnover firm.

10 Today, Arup has a commanding presence that is steadily expanding. Arup s strategy of diversification across geographies and business segments means that the global profile of the firm is constantly evolving.

11 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.

17 What is BIM?

18 BIM is 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.

19 BIM Explained Data Value Element ID j Element type Pump 4j-b Part No Manufacturer Prestige Net weight 1.87t Service interval O&M Ref Programme code 5,000 hours TTA-4 WP4-L2-C34 Install date Commission date Residual risks a/d, 6, 7, 9b

20 BIM means different process Architect Architect Civil Engineer Structural Engineer Civil Engineer Structural Engineer Property / Client Services engineer Property / Client Shared BIM Model Services Engineer Maintenance Manager Control engineer Maintenance Manager Control Engineer Construction Manager Construction Manager Several partners, each with different, yet still complimentary documentation Several partners, one single coordinated model

21 BIM is INput Geometry Components Spaces Materials Occupancy Performance Parametrics OUTput Analysis Simulation Compliance Exploration Optimisation Operation Maintenance

22 Lifecycle Information Management - Communication errors and loss of project information % 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!

23 Return of Investment ROI - 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.

24 Better Decisions based on better information

25 Constructing the Business Case for BIM Effort expended Traditional process BIM process Project progression The MacLeamy Curve.

26 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 A study of 32 major projects, Stanford University Centre for Integrated Facilities Engineering

27 Standards, Methods and Procedures

28 Important BIM Standards

29 BS1192: Common Data Environment Shared WIP WIP WIP Publish Archive Stage Work in Progress Shared Published Documentation Archive Description Non-verified design data used by in-house design team only Verified design data shared with the project team Co-ordination and validated design output for use by the total project team Project history maintained for knowledge and regulatory and legal requirements

30 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). - Already part of pre-qualifications.

31 BIM as a modelling tool LEED compliant

32 BIM during the building works Connection with Construction Management programs (ie Primavera) Time planning visualisation (4D Planning)

33 BIM as a modelling tool Air movement(cfd)

34 BIM as a modelling tool Energy Façade energy radiation study Studies of energy demand limitation through a 3D model Comparative Energy Demand graphs

35 BIM as a modelling tool Thermal bridges

60 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

61 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

64 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

65 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
