1 MP BIM at the Heart of the MEP Subcontractor Business Damien Legrand Sophie Montenot BIM Business Development Executive MEP BIM Manager 1

2 Class Summary Dive into the heart of an MEP subcontractor business and experience the challenges and requirements associated with a BIM delivery process. See how they develop their internal strategies and processes to optimize the delivery process. Topics include implementing new workflows bringing the engineers to the centre of the model; developing new methods to exchange information enabling a high level of coordination and QA for the duration of the project 2

3 Learning Objectives At the end of this class, you will be able to: Analyze project requirements and develop a project BIM strategy accordingly Implement new workflows using the model as a core source of information Create a new range of deliverables to support internal and external processes Measure and monitor the overall efficiency of the process 3

4 Agenda Introduction Key BIM comcepts for an MEP Subcontractor The project and the MEP Subcontractor Situation 1: generating shop drawings Situation 2: spatial coordination and clash detection Situation 3: Managing the services openings (CBW) request process Situation 4: Reviewing the model from an engineering point of view Conclusion 4

15 Key BIM concepts for an MEP Subcontractor 15

16 Factors impacting the BIM strategy The contract The deliverables (2D) The internal BIM processes and standardisation The project execution plan The working relationship developed with other parties involved Challenge = coordinate all these factors in an integrated delivery process 16

17 Situation 1: Production of Shop Drawings 17

18 Situation 1: MEP Model characteristics External references for Architecture and Structure Zoning to limit the sizes of models Workset structure : one workset per trade Display settings: filters to enable a colour coding Library Management: standardisation of the families in use 18

19 Situation 1: MEP Model life cycle Integration of external references Development of the construction model based on the consultant drawings Spatial Coordination CSD drawings preparation and issue Trades shop drawing preparation and issue Integration of client and consultant comments Start of revision 1 19

20 Situation 1: The shop drawings pdf directly from Revit Main reason to keep in Revit : Time constraint : need to to modify and revise Consultant only reviewing and marking drawings, no need to edit them Step 1: Finalise the plan view Apply view template to control all graphic display Set the view discipline to mechanical Set diplay mode to hidden line to show the services underneath 20

21 Full-Screen Layout Image Size (1,920 x 1,000 pixels) 21

22 Situation 1: The shop drawings within revit Step 2: Create the centre line overlay Duplicate the main view Turn off the visibility of all objects except pipes Change the detail level to coarse Overwrite the pipe settings to centreline 22

23 Full-Screen Layout Image Size (1,920 x 1,000 pixels) 23

24 Situation 1: The shop drawings within revit Step 3: Create the assembly drawing Insert the main view first onto the drawing sheet Insert the centerline drawing on top Use the drawing grids to align the two views together 24

26 Stadium Only 168 CSD drawings 672 Shop drawings 26

27 Stadium Only 168 CSD drawings 672 Shop drawings 27

28 Stadium Only 168 CSD drawings 672 Shop drawings 28

29 Situation 1: Converting the drawings to ACAD Main reason to convert to ACAD: because the contract says so Fabrication and pre-frabrication purpose Step 1: Analysing the ACAD standards 29

30 Situation 1: Converting the drawings to ACAD Step 2: Iterative export process 30

31 Situation 1: Converting the drawings to ACAD Step 3: ACAD Macro using the Revit API 31

32 Situation 2: spatial coordination and clash detection 32

33 Situation 2: Coordinating external references Model Revision Matrix It is critical to coordinate the timing of new revision of the architectural and structural model with the internal coordination process. Combining several models to coordinate one area: The problem of the zoning different in each discipline impacting on file size and performance 33

35 Situation 2: Coordinating external references Model Revision Matrix It is critical to coordinate the timing of new revision of the architectural and structural model with the internal coordination process. Combining several models to coordinate one area: The problem of the zoning different in each discipline impacting on file size and performance 35

36 36

37 Situation 2: Model Review and pre-coordination test Intra Trade clashes For example a duct clashing with a duuct Non constructible assemblies For example a piece of pipe less than 50mm long System connectivity Workset settings For example a cable tray drawn in the Fire Safety workset Relative position of ceiling hosted elements Direction of slope for drainage pipes 37

39 Situation 2: Clash Test and resolution Navisworks 39

41 Situation 2: services opening (CBW) 41

42 Situation 3: Managing the CBW requests process CBW accuracy and traceability Collaborative work with Structural and Architectural department Getting builder s work holes in the right place on a large project is very difficult and the failure to get it right is one of the biggest causes of rework in the construction process: More labor, more time, more cost Loss of opportunity to focus on critical path activities With BIM we can improve the proportion of holes which are cast/cored/cut in the right place first time. 42

43 Situation 3: Managing the CBW requests process The Flag family Faced based components Site category ID parameters Unique ID number Status Dated created Serices type 43

44 Situation 3: Managing the CBW requests process A Revit model of the slab openings as sent to the main contractor 44

45 Situation 3: Managing the CBW requests process Combined models to produce the CBW drawing Floor plan annotated List of all the opening requests 45

46 Situation 3: Managing the CBW requests process Callout plan for the congested area 46

47 Situation 3: Managing the CBW requests process Coordination Meeting Drawing annotated manually during the meeting 47

48 Situation 3: Managing the CBW requests process The CBW model is updated accordingly The flag changes colour to reflect their new status 48

49 Situation 4: Reviewing the model in an engineering sense 49

50 Situation 2: Reviewing the model in an engineering sense Need to verify and validate the information stored in models Not efficient to wait for a 2d drawing to be produced and then mark it up DWFx, 3D pdfs,navisworks freedom are great for visualisation Need to query the engineering information attached to the model Example using the API : the pressure drop macro 50

51 Situation 2: Reviewing the model in an engineering sense The Pressure Drop Macro Display on screen the pressure drop of any object of a system Can copy the pressure drop of multiple objects to a user define parameter in order to tag it easily and produce a calculation note Challenges A lot of manual editing of the library parts to assign the right ashrae table The scale of the project forces the services networks to be split in different models 51

52 Situation 4: Reviewing the model in an engineering sense Display the pressure drop of an element Pressure drop value copied to a parameter for tagging 52

53 Conclusion 53

54 Conclusion Technology cannot do it all by itself Integrated BIM operation processes adapted to the situation and the project Technology doesn t manage itself Strong BIM project management process Technology is not perfect by itself Adaptability is a key strength 54
