My up coming presentation in Singapore on 30th October 2009

1. 1 BIM as a solution for sustainable construction and maintenance

2. BIM as a solution for sustainable construction and maintenance Lifecycle of the building BIM for construction BIM for maintenance 2

3. Sustainable Sustainability means meeting the needs of today without compromising the ability of future generations to meet their needs. The construction process itself generates significant quantities of waste: about a fifth of all waste arising are attributable to the construction sector. Sustainability of the construction business How green is the building: Energy consumption during usage Construction Maintenance Demolition 3

4. Lifecycle of the building 4

5. Construction – How can BIM save environment Up to 40% of all solid waste is contributed to construction 10-30% of construction material is wasted during construction Work at temporary site  difficult to arrange recycling logistics “Better to deliver too much than too little” Design mistakes demolish / rebuild In-situ concrete  formwork is one of the biggest waste sources Delay in construction in expensive, “material is cheap” But is it “cheap” from the environment point of view? 5

6. BIM enables better design Better design – less errors – less material waste More accurate design – no surplus material 6

7. BIM communicates directly with procurement Accurate material lists including scheduling can be derived from the model to the financial and material management systems 7 API / .net

8. BIM communicates with the machinery CNC data directly from the model No “human errors” – less waste material 8 CNC - DSTV

9. Integration from design to production Design Export Production CNC

10. BIM supports IBS Industrialized Building System (IBS) transfers big part of construction work from the (always temporary) construction site to permanent factories BIM tool includes libraries of components defined / accepted / allowed to be used thus “forcing” standardization 10

11. BIM supports IBS 11 From site to the factory -more effective -less labor -less waste -easier to recycle

12. Building maintenance – facilities management Very little of the huge amount of information created during the design and construction is transferred to the facilities management. During the life cycle of the building, the basic information is collected over and over again for different reasons How to transfer relevant information in a usable form from construction to facilities management? How to manage facilities management information? Drawings, tables, database, schedules etc. supported by specific applications BIM for facilities management Selection of an application(s) depends heavily on building(s) to be managed. 12

13. BIM knows exactly what you have – and where Modern building has unbelievable amount of equipment connected to it: Piping, AC, electricity, surveillance, fire extinguisher, solar panels, batteries, control systems, IT infra…… Most need regular maintenance All need replacement / repair at some state Condition based maintenance programs Regular checking and condition information collecting BIM can be a central database supporting building maintenance Computer simulated as build environment Instead of fragmented documents 13

14. COBIE - by US Army facilities management and Building Smart The Construction-Operations Building Information Exchange (COBIE) format facilitates the delivery of building information during planning, design, construction, and commissioning for delivery to facility owners and operators. The information required by COBIE is already required by design and construction contracts (as paper or “e-paper documents). Information transfer for Facilities management applications 14

22. Challenges for BIM based maintenance Detailed as build model(s) is needed From the construction process Laser scanning Integration of all related information & documents One environment to hold all the information 3D PDF (import from via IFC) IFC ???? Costs control (Financial systems) to be tightly integrated No “one suits all” solution available 19

23. Benefits from BIM based maintenance Cost of operation and maintenance is more predictable and reduced Building system controls may monitored and tuned in real time Crisis management quick understanding affects - water leakage etc. Buildings life may extended Easier to modify and redesign Condition remains better 20

24. Summary BIM for construction Integrated work (and information) flow up the machinery and site  less errors, less waste From (adhoc) site work to industrialized process BIM for building maintenance Transfer better information from construction to maintenance Better knowledge of assets Know what you have and where 21
