Bim For Construction And Maintenance Singapore 09 Oct30 Ari Nassi

  1. 1. 1<br />BIM as a solution for sustainable construction and maintenance<br />
  2. 2. BIM as a solution for sustainable construction and maintenance<br />Lifecycle of the building<br />BIM for construction<br />BIM for maintenance<br />2<br />
  3. 3. Sustainable <br />Sustainability means meeting the needs of today without compromising the ability of future generations to meet their needs.<br />The construction process itself generates significant quantities of waste: about a fifth of all waste arising are attributable to the construction sector.<br />Sustainability of the construction business<br />How green is the building:<br />Energy consumption during usage<br />Construction<br />Maintenance<br />Demolition<br />3<br />
  4. 4. Lifecycle of the building<br />4<br />
  5. 5. Construction – How can BIM save environment <br />Up to 40% of all solid waste is contributed to construction<br />10-30% of construction material is wasted during construction<br />Work at temporary site  difficult to arrange recycling logistics<br />“Better to deliver too much than too little”<br />Design mistakes demolish / rebuild<br />In-situ concrete  formwork is one of the biggest waste sources<br />Delay in construction in expensive, “material is cheap” <br />But is it “cheap” from the environment point of view?<br />5<br />
  6. 6. BIM enables better design <br />Better design – less errors – less material waste<br />More accurate design – no surplus material<br />6<br />
  7. 7. BIM communicates directly with procurement<br />Accurate material lists including scheduling can be derived from the model to the financial and material management systems<br />7<br />API / .net<br />
  8. 8. BIM communicates with the machinery<br />CNC data directly from the model<br />No “human errors” – less waste material<br />8<br />CNC - DSTV<br />
  9. 9. Integration from design to production<br />Design<br />Export<br />Production<br />CNC<br />
  10. 10. BIM supports IBS<br />Industrialized Building System (IBS) transfers big part of construction work from the (always temporary) construction site to permanent factories<br />BIM tool includes libraries of components defined / accepted / allowed to be used thus “forcing” standardization <br />10<br />
  11. 11. BIM supports IBS<br />11<br />From site to the factory<br /> -more effective<br /> -less labor<br /> -less waste<br /> -easier to recycle<br />
  12. 12. Building maintenance – facilities management<br />Very little of the huge amount of information created during the design and construction is transferred to the facilities management. <br />During the life cycle of the building, the basic information is collected over and over again for different reasons<br />How to transfer relevant information in a usable form from construction to facilities management?<br />How to manage facilities management information?<br />Drawings, tables, database, schedules etc. supported by specific applications<br />BIM for facilities management<br />Selection of an application(s) depends heavily on building(s) to be managed. <br />12<br />
  13. 13. BIM knows exactly what you have – and where<br />Modern building has unbelievable amount of equipment connected to it:<br />Piping, AC, electricity, surveillance, fire extinguisher, solar panels, batteries, control systems, IT infra……<br />Most need regular maintenance<br />All need replacement / repair at some state <br />Condition based maintenance programs<br />Regular checking and condition information collecting<br />BIM can be a central database supporting building maintenance <br />Computer simulated as build environment <br />Instead of fragmented documents<br />13<br />
  14. 14. COBIE - by US Army facilities management and Building Smart<br />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.<br />The information required by COBIE is already required by design and construction contracts (as paper or “e-paper documents).<br />Information transfer for Facilities management applications <br />14<br />
  15. 15. Major overhaul for the building – role of BIM?<br /><ul><li>Refurbishment and enlargement project in downtown Helsinki
  16. 16. Stockmann: The biggest department store in Northern Europe
  17. 17. Ready 2010
  18. 18. Retail area 50,000 m2</li></ul>15<br />

  22. 22. Challenges for BIM based maintenance<br />Detailed as build model(s) is needed<br />From the construction process<br />Laser scanning<br />Integration of all related information & documents<br />One environment to hold all the information<br />3D PDF (import from via IFC)<br />IFC<br />????<br />Costs control (Financial systems) to be tightly integrated<br />No “one suits all” solution available<br />19<br />
  23. 23. Benefits from BIM based maintenance<br />Cost of operation and maintenance is more predictable<br />and reduced<br />Building system controls may monitored and tuned in real time<br />Crisis management<br />quick understanding affects - water leakage etc.<br />Buildings life may extended<br />Easier to modify and redesign<br />Condition remains better<br />20<br />
  24. 24. Summary<br />BIM for construction<br />Integrated work (and information) flow up the machinery and site  less errors, less waste<br />From (adhoc) site work to industrialized process <br />BIM for building maintenance<br />Transfer better information from construction to maintenance<br />Better knowledge of assets<br />Know what you have and where<br />21<br />
