HISTORY TO ACHIEVING B.I.M. 2007

2012

• 3D Modelling in Revit • Basic Annotation in Acad

Exported 2D slices, plans etc. from 3D Model and Annotate in Acad using Text, Dims, Hatches and 2D Line work, Some generic drawings were done completely in 2D Acad

All Plans and sections were taken from the 3D Model and Annotate in Revit using Text, Dims, Hatches and 2D Line work, Some generic drawings were done in Acad and imported /converted to Revit 2D Drafting view

Revised Method of modelling to allow the importing of structural geometry and collaboration. All Plans and sections were taken from the 3D Model and Annotate in Revit with the use of BIM Automatic annotation using Furniture/equipment Tags, Wall tages etc. Some Revit 2D Drafting views for generic drawings are used

Above Plus the introduction of ‘Schedules’. Starting to use phasing and phase filters to better effect.

Use of revised method of modelling to allow more automated schedules to be generated.

Modelling Approach

‘Pre-Analysis’ modelling approach, gathering all the information about the detail before starting to model.

“Good for Converting from Acad but has its Cons!”

Converting From CAD to REVIT

Picking a detail to start the Conversion

Questions a Modeler Generally has:1. Can the detail actually be built?2. What does the detail look like/does it need to be worked out?3. Can the software do what I want, How do I model it?

Model a detail you’ve already done before / complete. You know it works.You know how it looks likes.You can concentrate on your modelling skills

‘Pre-Analysis’ Step 1- Draw detail and Annotate every object in the detail.

“Can be freehand or an existing AutoCAD drawing”

‘Pre-Analysis’ Step 2- Mark a number beside each annotation on your sketch

Column 1 - #This is the number that links the number in the table with the number on your detail. Column 2 - Brief descriptionWrite a brief description of the object Column 3 - 2D/3DReview the brief description and consider weather you think you should model it or draft it. If the object will be seen in more than one view type it should probably be modeled. Column 4 - Modeling typeDecide what revit tool you will use to create the proposed component, is it a fl oor or a wall or a custom generic model family, etc. Column 5 - Family typeAfter you decide the method of modelling then fi gure out what family type within that revit tool your going to use, this also help you decide if you need to create a new family that is not already in your model or template

‘Pre-Analysis’ Step 3- Fill out a 5 column Table

“You now have a self-written tutorial to follow”

Grids / Levels / Ref Planes Detailed Components and Annotation

Object Position

‘Pre-Analysis’ What other pieces of information can you get from your detail?

System Family Check

“Draw as many rectangles as you can”

ProsGood to build up your modelling skills and introduction to the different tools, Allows you to make a plan of attack on the modelling side.

ConsYou have to know a lot before your can start, this can be off-putting and generally the time luxury is not available. The list of Items you have to know before starting could be as long as this;

‘Pre-Analysis’ Conclusion

Items that could be listed01 Worksets02 Phases02 Levels03 Grids04 Wall types05 Curtain wall types06 Floor types07 Ceiling types08 Column types09 Beam types10 Door types11 Window types12 Stairs types13 Railing types14 Roof types15 Profi les/Wall sweep16 Furniture17 Electrical Fixtures/Lights18 Mechanical Components 19 Entourage20 Site Components20 2D components21 2D Line work22 Filled region

This method identifi es which are the primary objects, secondary objects, etc. and in which order they should be modelled.

In this detail the general rules are 1. The curtain Wall must be 50mm from slab edge2. The slab edge is to line up with the edge of steel beam3. The Steel Beam is to be Centred on the Grid line

These rules gives us a modelling order of1. Grid line is place fi rst2. Beams are placed3. Floor outline is drawn with edges to align with beam4. Curtain wall to be drawn with an offset of 50mm

Working Building Information Model Working Construction SiteTo produce full construction drawings from a slice of a 3D model with minimal 2D work carried out took an extra level of detailing within the model. This also started to setout the guidelines for collaborative work with consultants in regards to responsibility and ownership of different parts of individual buildups. The Structural floors we’re seperated from the finishes to allow the architect and structural engineer to

Construction developing on site similar to the BIM model with different sub-contractors taking responsibilities for different elements within the construction. An example is the main precast structural concrete slab by one contractor and terrazzo floor finish and rigid insulation installed by another.

Preparation (2-3 Hours (Max))1. Prep Autocad fi les for importing, clean, explode, purge etc.2. Save Autocad fi les into the same import folder (near where the revit

central fi le folder will be located on the server)

Setup (1 Day (Max))1. Start new revit fi le base on the ‘Template’;2. Create Worksets, (apply list in Revit standards document);3. Save Central fi le (Naming convention per Revit standards document)4. Save Local fi le (Naming convention per Revit standards document);5. Create Levels (main plans), Enter elevation to create. Organise

browser by applying ‘user’ parameter;6. Next step is to Link base Autocad Plan/Site plan (done in ground

fl oor plan), Pin drawing;7. Set Project North using the ‘Scope box’ Tool and rotating it 8. Set Extents, move elevations so that they are clearly around

intended building/zone. Draw reference planes of out edges of building/zone, enter East elevation and drag the levels so that they start/stop on these reference planes, Repeat for the South elevation;

9. Set Grids, Either trace from the Autocad fi le or draw new ones over the acad fi le;

10. Now Import remaining Autocad fi les and move into correct location, using grid lines as the guides to help locate the plans properly (if you have no grids, reference planes must be drawn to help you align the different Autocad plans);

11. Setup Working views (duplicate original levels) rename the ‘copy‘ view with your initials at the front of the level name, organise browser by applying ‘user’ parameter;

12. The fi le is now ready to start modelling;

Modelling - Stage 1 (5 Days)Building• External Walls, Using ‘place holder’ generic walls types, model in

the basic external walls. (windows and curtain walls will come later, just enclose building to begin with);

• Floors, Using ‘place holder’ generic fl oor types, model in the basic fl oor outline using the external walls as the boundary. (Floor fi nishes will come later, just the basic shape to begin with);

• Roofs, Using ‘place holder’ generic roof types, model in the basic Roof outline using the external walls as the boundary. If it is a pitch roof type generally set the boundary 300mm from the outside edge of the external walls. Place a section in the model and move roof height into the correct location;

• Columns, Using ‘place holder’ generic column types, place the main columns / structure, check the top of columns meet the correct fl oor slab or roof level above;

• Internal Walls, Using ‘place holder’ generic wall types (usually 100, 140 or 200mm) model in the internal layout, trace autocad plan if available, check the top of walls meet the correct fl oor slab or roof level above;

• Doors, Using ‘place holder’ generic door types, place the doors to each room in the model. Duplicate the basic door and create alternative sizes if the size you require is not in the template;

• Rooms, Place rooms into the project and rename as you move around the plan.

• Windows / Curtain Walls, Generally all windows will be drawn as curtain walls to start off with as they are very fl exible in their shape and divisions and do not require advanced window families to be available in the server library. We will generally use 100mm deep mullions for small windows and 150mm or 250mm deep mullions for shopfronts to begin with until we know actual size. The curtain wall type should be set to ‘automatically embed’ so it cuts its own shape out of the external walls;

• Sweeps, profi les custom canopies, Add any extra features, gutter, reveals or profi les to the external walls and roofs. Canopies are usually a roof or fl oor with a special edge profi le;

• Ceilings, Place default ceiling height across the project using external walls and internal walls as the outline. If there are bulkheads, use a generic 50mm or 100mm wall type as vertical part of the bulkhead (if the bulkhead is curved us a custom sweep;

Furniture (this may be done after site plan works depending on the type of project, the deliverables requested and deadlines);

Modelling - Stage 1(Cont..)Site Plan• Toposurface, Model Toposurface by importing the survey Acad fi le,

then place individual points over each level until the surface is built;

• Roads, Defi ne roads outside of the site by adding a ‘sub-region’ to the toposurface;

• Building Pads, Cut the building shape and car park shape out of the toposurface by using Building Pads;

• Car park surface, Place the car park surface by using generic fl oor types. Slope the car park by adding a ‘sloped arrow’ to the fl oor;

• Car park components, Using the component tool place items such as car spaces, road marking signs, note the components should be hosted by the main slab (fl oor);

• Walkways and custom road markings, These are created by modelling a 5mm fl oor type (usually white for marking, green for walkways). If the main car park surface is sloped you should copy the ‘sloped arrow’ from the main slab and paste it into the sketch of the walkway. Set the fl oor 5mm offset from level so it is above the main slab;

• Kerbs, Model Kerbs or planter walls by using generic wall types usually 150mm or 215mm thick. Edit profi le if required;

• Grass/Planter, Model Grass/Planter areas with a generic fl oor type with grass fi nish;

• Site furniture, place bollards, bins, benches etc. by placing components loaded from the library;

• Site entourage, Add for rendering and visuals, place trees and cars to the site, note the entourage should be hosted by the main slab (fl oor);

• The initial modelling stage is complete, now it is time to setup views for printing and perspectives for rendering;

Stage 1 Stage 2

Views & Annotation - Stage 1 (3 Days)Plans• Setup Printing Views (duplicate original levels or working views)

rename the copy with to the appropriate printing title, organise the browser by applying ‘01 Printing Views’ to ‘user’ parameter;

• Create and apply Scope box to view, Alternatively drag the crop region to desired extents;

• Apply View Templates to plan views to get suitable graphics. If required change Visible Graphics (VG), Overwrite Elements in view or use the Linework Tool for visual clarity;

• Annotate plan views with planning key notes, levels and dimensions as required;

• For presentations Colour & Shadows are added to plan views. These are generally to be in addition to black and white plans;

Elevations• Place new Elevations/Elevation marker into the model if new

elevation views are required. Rename with to the appropriate printing title, organise browser by applying ‘01 Printing Views’ to ‘user’ parameter;

• Move elevation Extents and Depth to suit each elevation; • Apply View Templates to Elevation. Set shadows and sunlight to

get suitable graphics. If required change Visible Graphics (VG), Overwrite Elements in view or use the Linework Tool for visual clarity;

• Annotate Elevations views with planning key notes, spot elevations and dimensions as required. Use 2D entourage Detail Components such as planting and people to show more context;

• For presentations Colour & Shadows are added to elevation views. These are generally to be in addition to black and white elevations;

Sections• Place new Sections into the model if new section views are required.

Rename with to the appropriate printing title, organise browser by applying ‘01 Printing Views’ to ‘user’ parameter;

• Move elevation Extents and Depth to suit each section; • Apply View Templates to section. If required change Visible

Graphics (VG), Overwrite Elements in view or use the Linework Tool for visual clarity;

• Annotate Sections views with planning key notes, spot elevations and dimensions as required. Use 2D entourage Detail Components such as planting and people to show more context;

• For presentations Colour & Shadows are added to elevation views These are generally to be in addition to black and white elevations;

Site Plans• Duplicate (-without detailing) the fl oor plan. Change the cut level to

show the roof plan if required; • Create and apply Scope box to view, Alternatively drag the crop

region to desired extents; • Annotate plan views with planning key notes, levels and dimensions

as required; • For presentations Colour & Shadows are added to plan views. These

are generally to be in addition to black and white plans;Create Sheets• Create New Sheets for each plan, section & elevation views. Title

and number each sheet according to the standards document;• Place Views onto sheets. For plan views turn on sheet grids in the

properties and align each view to the same space;• Add keynotes, project notes and legends to sheets as required. Print

and review drawings; Print and Review• Print Sheets and review. Make changes and additions as required;• Issue drawings for design review or planning as needed;• At this stage the model should be backed up and recorded as a fi le

separate from the ‘central fi le’ model;

Modelling - Stage 2 (20 Days) Develop Design• Develop grid and pin it; • Identify key sections, elevations and part plans. Create location

plans and locate them; • Detail and develop the fabric of the building, develop the structural

scheme along side; • Identify wall types, fl oor types and roof types needed in the

project. Create these new type and number sensibly in line with standards document;

• Walls, Roofs and Floors that will become structural elements and eventually part of the structural model should be modelled separately. Eg. Lift cores, structural fl oor slabs. These element will be turned off later;

• Replace generic walls with developed wall types. Similarly this should be done for roofs;

• Floors should be separated into structural fl oors and architectural build ups. Floor fi nishes (except large fi nishes such as terrazzo or concrete screed) should not be included;

• Structural model should be developed by engineers and linked to your model;

• Mechanical model should be developed by engineers and linked to your model;

• Initial ceiling design should be settled, and Mechanical & Electrical object should be developed inconjunction with M+E engineers;

• Update curtain wall window glazing types to correct sizes of frames etc as the design develops;

• Model detail elements such as copings, fl ashings and cills as identifi ed in sections where practical with wall sweeps and reveals.(Some fi ner detail will be done in 2D detail components later);

• The site layout should be checked: Updated wall locations and changing thicknesses can effect car parking spaces and clear widths;

• Where no consultant model is to be provided, link consultants Autocad information and update your model as required to show information eg. Condensate upstands etc.;

Stage 3 Stage 4

Stage 5 Views and Annotation - Stage 2 (15 Days) This is a general overview of the workfl ow for developing annotated drawings.• Setup Printing Views (duplicate original levels or working

views) rename the ‘copy’ view with to the appropriate printing title, organise browser by applying ‘01 Printing Views’ to ‘user’ parameter;

• Create and apply Scope box to view, Alternatively drag the crop region to desired extents;

• Apply View Templates to all views to get suitable graphics. If required change Visible Graphics (VG), Overwrite Elements in view or use the Linework Tool for visual clarity;

• Copy blank keynotes onto views. Print view and write down notes. Fill in the notes in the schedule view and place in correct location in the views as required;

• Use tags, dimensions, spot levels, keynotes, fi lled regions and detail components to annotate views;

• Use ‘Filled regions’ and detail lines to create site conditions over topography that does not show any buildup;

• Fill out and check schedules: door schedules, window schedules and room fi nish schedules in particular. Furniture schedules should be checked that the items on the schedule are activated properly;

• To accompany the door schedule elevations in drafting views should be created. These are done in drafting lines and 2D annotation.

• To accompany the curtain wall schedule, elevations of the glazing should be created. These elevations should be hidden at large scales;

• To accompany the Window & Louvre schedule, a legend view of the window blocks should be created;

• Generic details should be created in drafting views. These should be annotated and referenced in sections and plans. They should be placed on sheets;

• Sheets should be created and the views should be added to them. plans should be placed on sheets using sheet grid guides where possible. For sections and elevations the reference number should match that section number/letter;

• Schedules, legends, key notes, project risk notes should be added to each page;

• A construction legend should be created that references every element that are only described with automated tags. Also on this page there should be symbol legends, key notes legends and anything else that is referenced in the drawing set;

• Sheets should be printed, checked and reviewed;

General Workfl ow (Sections)Generally sections and detail views have the most 2D work. To make a more presentable section we add;

• Wide Dashed drafting lines for DPM and DPC• Repeating detail for block work joints in section• Filled region for the foundation trench infi ll(connects

with the hardcore in the base of the fl oor slab)• Import autocad hatch patterns that are not available

in revit, some good download sites are http://www.cadcorner.ca/hatch.php and http://www.autocadhatch.com/

• Wide drafting lines for the steel lintel• Thin drafting lines for the X inside of the cut ceiling

joist and rafters• Spot elevation makers• Insulation tool for roof insulation• Splitting the section marker lines• Text notes and Leaders

TextStandard text, can get outdated and updates can be missed, the Human Error factor is much higher.

Notation

Automatic TagsUse ‘Tag by Category’ Requires a Legend with a list of each component buildup, Really Useful

Sheet Key notesDone a symbol with a Note Block Schedule, useful, the information is all in one location (the schedule) but the symbols could be pointing at the wrong object or position my not be updated with model changes

Key notesCan be great but you need a full understanding of the NBS specifi cation codes, Can be limiting for details as it only allows you to enter one code per item, walls might have 4-5 layer in them etc.

Extra Tips and Tricks1. TIPS FOR BEGINNERS

1 Tips for beginners

• Work in multiple views. When you are working on your model make sure you completely understand the extents of what you are editing. I don’t believe this can be done from any single orthogonal view. Working in 3D is great and should be done as much as possible as you can quickly see how the elements you are manipulating interact with elements around them (make use of section boxes to do this also). Too many times I see users trying to make changes only in a plan and then a week later discovering all the issues they have made for themselves in their sections...

• Plan your project! Sit down with pen and paper fi rst, especially for large projects or projects of an unfamiliar type, and work out exactly how you are going to document it. Are you going to use groups or links or design options? If so what are the issues in doing this and how are you going to resolve these? How is the project team going to work? Important questions that need to be resolved as soon as possible, preferably before the model is started.

• Make use of your model as much as possible for drafting and details. If you use your model as the basis for your details then you can identify issues before they get to site. Yes of course you should still draft over these for details, but using the model as the basis you know when your details need to be updated or re-looked at.

• Minimise number views in the project, delete any extra views that are not required to keep the browser clean

• Only model what you need, do not spend hours modeling vast detail if it is not required or seen

• Don’t over constrain the model as you will get lots of error messages

• Purge / delete unused ACAD fi les

• Do not to hide Acad underlays with the hide element command, rather go into the VG and un-tick.

• Model correctly from the beginning

• Mind what workset you are on,

• Tune your shortcuts on the ‘user interface’ in the view tab on the ribbon

Extra Tips and Tricks3. COORDINATION BETWEEN CONSULTANT MODELS

3.1 Integrated modelsOne of the most diffi cult task is to manage the coordination between our model and our consultant’s models. This can be especially hard as the accuracy of Structural and MEP drawings is far looser this inaccuracy tends to get copied across in to their Revit/BIM Models.

3.2 Importing/ Linking fi les. The Shared coordinates should be based on the architectural model which mean an import of ‘Origin to Origin’ should import the models correctly without any moving or rotation of the consultants models.

3.3 Updating FilesWhen updating the consultant models that have been previously placed in the model you should use the option ‘reload from’ in the ‘Manage Links’ Dialogue. This option keeps any graphic overwrites and fi lters that you may have previous placed and wish to retain, if you delete the model and load a new fi le these setting will be lost.

3.4 Overwriting Graphics of linked fi leTo overwriting graphics of linked fi les, enter visible graphics (VG) then on the ‘Revit Links’ tab, select the ‘Display Setting’ and change from ‘By host’ to ‘Custom’. Now select the custom setting in the fi rst tab that opens. Enter into either the ‘model’ or ‘annotation’ tab, select the drop down list to the right of Model Categories, Change from ‘by host’ to ‘Custom’. Now all the options to overwrite the graphics become available for the linked fi le. Note these changes can be save to a view template and apply to other views.

3.5 Model review & coordinationReview model coordination and accuracy, note that if any structural or MEP element is out by 25mm it will be noticeable in our drawings as we xref their object into our printing views, all in accuracies should be highlighted and a markup sent to the relevant engineer.

3.6 Design & Model Review Workshops It is now becoming standard practice to have ‘Design & Model Review Workshops’ where the whole design team meets up and all models are overlaid and issues are talked through using 3D cut sections, perspectives, 2D plans, elevation and sections. A fast machine is required to show all the integrated models on screen at once.

2. BIM MODEL MANAGER - ROLE AND RESPONSIBILITY

2. BIM Model ManagerOn each project there will be a 1. Senior Project Architect (Team Leader) and 2. Project team (Revit users) comprising of several people with varying

experience in both architectural practice and software usage.

The introduction of the ‘BIM Model Manager‘ role will be the responsibility of the most experienced Revit user in the ‘Project team’.

The ‘BIM Model Manager’ will make decisions of how certain objects are modelled and information is coordinated. They should be responsible for but not limited to;1. File setup, correct template is used, the fi le is saved in the correct

folders on the server

2. Decide on how certain families are created\modelled and how the folders are organised

3. Keep track of worksets and that object are in their correct worksets,

4. Keep track of design options and what is inside the design option.

5. Naming of groups, views, sheets, design options, custom families are consistent

6. Custom families parameters so they schedule correctly, Sheet Keynote numbers are linked to the correct text specifi cation, Tags and type marks in object names match the type mark parameter.

7. Imported CAD fi le management, CAD fi le cleanup and renaming.

8. Coordinating / linking consultants fi les both REVIT & CAD.

9. Setting up Batch Printing sets

10. Setting up new Project Parameters

11. Opening other users local fi les incase there local fi les need to be checked or worksets relinquished.
