  8. 8. Need for modeling? • There has to be need for models from client • If you order a ”BIM”, it just confuse the designers. Different companies has different opinions what modeling is • Common language is missing without ”BIM execution plan” MEP Design, Tero Järvinen
  9. 9. Modeling = Designing • BIM modeling is not just for geeks or CAD- personell • BIM modelling is a different way to make design BIM is something else than producing paper drawings • Buildings will rise also without BIM • If you need only paper drawings, you should’t use BIM • BIM is tool for designers, contractors and building owners MEP Design, Tero Järvinen
  10. 10. Modeling requires: • Professionality from every participants • Common vision, where to aim in project • Wider collaboration comparing to ”normal” project • Understanding what other participants are doing • Mental Change MEP Design, Tero Järvinen
  11. 11. Process MEP Design, Tero Järvinen
  12. 12. ”Normal” project for designers: Design – Bid –Build –contract 1. Design tender from building owner (made by external project management consultant) 2. Design Offer -> Quality 40%, Cost 60% (or something else) 3. Light Preliminary Design (Diagrams, Serviceareas, 2D-main routes, no products selected, work specification) No coordination 4. Detail Design (Equipment database, diagrams, MagiCAD modelling) No coordination 5. Construction (nothing to do with BIM) 6. Facility Management (nothing to do with BIM) MEP Design, Tero Järvinen
  13. 13. ”Sophisticated” project for designers: ”Design–Bid–Build” or ”Somekind of partering” -contract 1. Design tender from building owner (made by external project management consultant) 2. Design Offer -> Quality ~70%, Cost 30% 3. Preliminary Design (Diagrams, Serviceareas, 3D-main routes, Equipment database, work specification, other documents) Coordinated process, no products selected 4. Detail Design (MagiCAD modelling) Heavily Coordinated process 5. Construction (Combied model in use) 6. Facility Management (not so much to do with BIM) MEP Design, Tero Järvinen

  20. 20. Spacetypes and Requirements SQL MEP Design, Tero Järvinen For starting of MEP design, requirementsfor Indoor Quality are needed • With colloboration of customer, maximum temperatures etc. has to be decided • With these requirementsMEP designer makes comfort and energy simulations for fullfilling the requirements. End result is a target value for each space, which MEP designer has to fulfill. (for example: Requirement: max. 26oC -> simulation -> target value 1.2kW cooling Requirements Concept Detail Construction Commissioning Maintenance
  21. 21. Service area charts MEP Design, Tero Järvinen Spaces with requirements are linked to service area charts (for exampleAir handling unit service areas) • Linking is made using ifcSpaces (IfcZones are created with external software to IFC file • Visualization: Solibri… or some other software (?) which understandIfcZones. IFC SQL Requirements Concept Detail Construction Commissioning Maintenance
  22. 22. Energy and Comfort simulations MEP Design, Tero Järvinen Dynamic simulation of energy and comfort is made according to the requirements, building model and service area charts. • Every space is simulated • Alternative simulations and comparisations for different envelopes, windows etc. -> beginning of LCC calculations IFC SQL Requirements Concept Detail Construction Commissioning Maintenance

  30. 30. MEP modeling MEP Design, Tero Järvinen • Easiest thing in MEP modeling is the normal use of MagiCAD in network modeling • Hardest thing in MEP modeling is the iterative process, revision management • MEP designer is last disicpline in process. Changes in Architect or Structural models affects to MEP models • There are quite a lot tasks in MEP design, which is not seen in other disicplines (simulation, diagrams, system design, equipment databases… etc.) • Designing is made first, modeling after that
  31. 31. MEP Design, Tero Järvinen How to make proper Models Modellers should have proper technical equipmens. Modelling starts after schematic design Continuous learning, stimulating enviroment Passion. Be proud of your models Courage to have challanges, need to take steps forward without knowing what will happen Understanding your on place in big picture, other participants are also doing same building – collaborative approach
  32. 32. Utilizing 2D and 3D models with AutoCAD -based softwares MEP Design, Tero Järvinen In MagiCAD system, architect 2D drawing is in use - same drawing what is in use when plotting MEP design to paper. Combiedmodels are in use with Navisworks. Two screens, Magicad in other, and Naviswork in other. From Magicad (Autocad), seperate navis-cachefile is saved to be viewed in combied model (nwc -> nwf) For efficient design, two screens is mandotory When making models according to COBIM 2012 requirements, just using MagiCAD is not enough.AutoCAD is not for collaborative 3D design, it is lacking useful 3D features, speed and teamwork capabilities.
  33. 33. MEP Design, Tero Järvinen Combied Models
  34. 34. Combied models 1/2 MEP Design, Tero Järvinen With using coordinated approach in combied models you can be sure your networks are in correct places • Combied models is mandotory when modeling networks in Detail Design phase. • With combied model, other disicplines have better understanding of networks (for example need of space etc. Software: Navisworks Tekla BIMSight Solibri IFC Arch, Struct, MEP- IFC files Requirements Concept Detail Construction Commissioning Maintenance
  35. 35. Combied models 2/2 MEP Design, Tero Järvinen • With combied model you can see all installation details you need for making networks installation possible according the design. • When installations are made according the design, you have first step for network model usage in Facility Management • Good Practice: before assembly in certain areas is started, you should present combied model of that area to MEP contractors. This is where you can make planning of assembly schedules and contractors can see the amount of networks belonging to other contractors. Software: Navisworks Tekla BIMSight Solibri IFC Requirements Concept Detail Construction Commissioning Maintenance
  36. 36. MEP Design, Tero Järvinen MEP BIM usage in Site Mainly usage of combied models – in very rare cases usage of MagiCAD models Contractor is not interested about calculations (pressure, flows etc.) First question from contractor: “What is the installation height of pipe/duct/cabletray?” In general, attitude to usage of combied models is positive

  38. 38. MEP Design, Tero Järvinen MEP model in site BIM models are in use in site office, and 3D-views are printed to paper for use inside building
  39. 39. MEP Design, Tero Järvinen MEP model in site Insulation installation of highest pipes are impossible -> pipes were lowered to gain more installation space (Slide: Jyrki Maalahti / SRV Oy)
  40. 40. MEP Design, Tero Järvinen MEP model in site Year 2008 MEP model made without structural model No information of beamheights inside the combied model. Only architectural model was in use when making MEP design Year 2009 With structural model MEP design change can be done
  41. 41. Technical Facility Management MEP Design, Tero Järvinen
  42. 42. MEP Design, Tero Järvinen BIM Management Process during building life cycle Back to Maintenance
  43. 43. Equipments MEP Design, Tero Järvinen FM system SQL For Facility Management point of view, network models are not really important Allmost all information for technicalFM is inside device database (and diagrams) IFC model do not have enough information for the need of FM Requirements Concept Detail Construction Commissioning Maintenance
  44. 44. Building Performance MEP Design, Tero Järvinen BAS system SQL Connected to BAS system and offering ”one value of building Performance” • Offering interface for Facility managementpersons, who are not capable to use BAS system • Offering interface for Building Managementto analyze building performance daily basis Requirements Concept Detail Construction Commissioning Maintenance
  45. 45.

  53. 53. Using spatial model (from bim) • Normally, architectal model do not have windows in early phases • Windows and walls can be created in energysimulation softaware to have multiple variations for example different procents (%) on windows in envelope (or window types, shadings etc. MEP Design, Tero Järvinen
  54. 54. Decisions need different metrics… By team working and using of BIM and efficient simulation it was possible to analyze 15..20 design solutions (renovation and new building) during 2 days workshop (School/daycare building in Syväniemi, Kuopio, Finland) E-value Carbon footprint Energy costs Indoor conditions PRE Model NovaMEP Design, Tero Järvinen
