The document discusses MEP design processes and the use of BIM. It provides information on: 1) The key phases of MEP design including schematic design, detail design, construction and facility management. 2) How BIM can be utilized across the different phases from requirements management, energy simulations, coordination of models, and use of models in facility management. 3) The benefits of using combined models for coordination between disciplines and for construction.

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. 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. 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. Process
MEP Design, Tero Järvinen

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. ”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)

- Simulations and visual information for

2. Detail Design
- Modelling of building according
the decissions made in Schematic

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

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. 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. 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. MEP Design, Tero Järvinen
Combied Models

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.

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.

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

37. MEP Design, Tero Järvinen
BIM in construction site
Contractors really look after models and do installations
according to model...

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. MEP Design, Tero Järvinen
MEP model in site
Insulation installation of highest pipes are impossible ->
pipes were lowered to gain more installation space

Year 2008
MEP model made without structural

No information of beamheights inside the
combied model. Only architectural model
was in use when making MEP design
Year 2009
With structural model

• 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.
