1. TM Complete Detailing for Concrete & Steelwork Brenden Picton / Paul Hellawell GHD

2. Revit Technology Conference 2010 Session Outline – Part 1: Steelwork The first part of the presentation will consist of showing how creating complex families will speed up your documentation process in regards to steelwork. The presentation will cover ; Nesting families; Linking family parameters; Demonstration of creating type catalogues to drive your families; and Demonstration of the importance of creating your families the same way each time. Introduction

3. Revit Technology Conference 2010 Session Outline – Part 2: Concrete The second part of the presentation will look at complex reinforcement detailing of a bridge abutment. The presentation will cover ; Typical reinforcing with shape codes; Tagging and detailing; Linking projects using shared coordinates; and Setting up your projects to speed up and improve documentation. Introduction

4. Revit Technology Conference 2010 Detailing Steelwork Connections in Revit - Options 2D Documentation - Relatively Quick but not fast; - Not ideal when everything else is 3D; - Doesn’t update when things move; - Only shows up in 1 view; and - No scheduling Part 1 - Steelwork Autocad Structural Detailing- Another piece of software to learn & buy; - Initial setup costs; - Fast; and - Until latest version – x32 bit

5. Revit Technology Conference 2010 Detailing Steelwork Connections in Revit – Options 3D Documentation –Time consuming; –Very few families available; –Limited functionality with Extensions Manager; and –Extensions manager only creates 3D extrusions that don’t schedule nicely. Part 1 - Steelwork However if we do document in 3D –Displays in more then 1 view; –Benefits of scheduling; –Better coordination; –Allows more flexibility with documentation; and –Can’t be ‘fudged’

6. Revit Technology Conference 2010 3D Connections Decision was made to detail connections in 3D. Part 1 - Steelwork –Have a good base of standard connections; –Get the information to the users; –Keep them relatively simple; and –Create families the same way. Use consistent parameter names between families, ie. Shared Parameters; Start to nest the connections into the framing families –Connections already modelled when you put the framing in

7. Revit Technology Conference 2010 Nesting Connections CHS + Fin Plate Example Take the normal, out of the box CHS family that comes with Revit. Save as ‘CHS + Fin Plate.rfa’ Part 1 - Steelwork Create your capping plate –Face Based family template –Use Type Parameters –Create ‘Types’ for each of the CHS sizes –Ensure you set the Family to ‘Shared’

8. Revit Technology Conference 2010 Nesting Connections Create your Fin Plate Family –Face Based family template –Use Type Parameters for Geometry constraints –Use Instance Parameters for Construction constraints, ie. Fin Plate Rotation –Create ‘Types’ for each of the CHS Sizes –Ensure you set the Family to ‘Shared’ Part 1 - Steelwork

9. Revit Technology Conference 2010 Nesting Connections Loading the connections into the CHS Family. –Place the capping plate on the edge of the CHS and lock to ref planes –Give the capping plate a label Repeat at other end of CHS Part 1 - Steelwork

10. Revit Technology Conference 2010 Nesting Connections Repeat the same process for the Fin Plates and lock them to the reference planes in the left of right views. Part 1 - Steelwork

11. Revit Technology Conference 2010 Linking Visibility Settings Click on the Right capping plate and open up the instance parameters Click on the grey box next to the ‘Visible’ parameter, create a parameter called ‘Capping Plate Right Y/N’ Repeat of Left capping plate and also both Fin Plates This allows you to turn the capping plates on and off as you desire Part 1 - Steelwork

12. Revit Technology Conference 2010 Linking Family Parameters Click on Fin Plate Right and open up its Instance Parameters Click on ‘Fin Plate Rotation’ and link it to a new family parameter in the CHS + Fin Plate Family Repeat for Fin Plate Left Part 1 - Steelwork

13. Revit Technology Conference 2010 Writing the Type Catalogue The family types should now look like this. The family is pretty much complete Time to write the Type Catalogue Part 1 - Steelwork

14. Revit Technology Conference 2010 Writing the Type Catalogue Take a copy of the CHS type catalogue that comes with Revit and save it with the same name as the CHS + Fin Plate family. Add the Fin Plate and Capping plate parameters in the top row as shown Add the Fin Plate and Capping Plate types for each CHS size as shown Part 1 - Steelwork

15. Revit Technology Conference 2010 Writing the Type Cataloge Ensure what you write into the.txt file corresponds to the family types in the Revit family Open a new project, load in a CHS and watch how your Fin Plate and Capping Plate are already modelled Because we created ‘Types’ for the plates, all of them will be loaded into the project when you bring in a CHS. However, the type catologue automatically sets the correct Fin and Capping Plate depending on CHS you want. If you don’t’ want them in your project, just delete them through the project browser or purge Part 1 - Steelwork

16. Revit Technology Conference 2010 Importance of Creating Families the same way 1.Easier and consistent usability for users 2.Consistent scheduling when using Shared Parameters 3.Makes your families inter-changeable Using the Fin Plate – Type 1.rfa family before, save as Fin Plate – Type 2.rfa Make the necessary changes you require Load this Family into the project Part 1 - Steelwork

17. Revit Technology Conference 2010 Importance of Creating Families the same way Click on the CHS and change the Fin Plate to Fin Plate – Type 2 All the functionality of the original Fin Plate is retained You can delete the Types out of the second Fin Plate and create a catalogue file to keep your families in order ‘Family Types’ are important. Although they clutter your project browser, they keep your model quick. And you can always delete or purge un-used family types. Part 1 - Steelwork

18. Revit Technology Conference 2010 Approach to Concrete & Reinforcement Detailing (Bridge Examples) Part 2 - Concrete

19. Revit Technology Conference 2010 Approach to Concrete & Reinforcement Detailing (Bridge Examples) Part 2 - Concrete Revit has flaws in some concrete elements. Separate project per complex concrete component Allows reuse of fully detailed concrete elements Consistency across projects Speeds up detailing time of subsequent projects Fully detailing bridges currently very painful however very accurate! Beam auto joining not helpful on bridges! –To prevent auto joining, use the complex beam and trusses template –Complex beam and trusses template cannot host reinforcement! –Use same workaround, create 2 families! Only certain family templates can host reinforcement –Be wary of changing family categories (eg: Generic model to Structural framing) –Workaround, build one family for in project, and one for detailing in separate project.

20. Revit Technology Conference 2010 We asked ourselves: Why Reinforce in 3D? Part 2 - Concrete Estimation – Materials and Weights Accuracy of information Starting to include bar fabricators (Integrated Delivery) Visible in more then 1 view

21. Revit Technology Conference 2010 Bridge Girder Example Part 2 - Concrete

22. Revit Technology Conference 2010 Rebar in section displays well Part 2 - Concrete Rebar in Elevation displays poorly in Revit –Workaround, use detail items and tags –Turn Rebar white & Transparent

23. Revit Technology Conference 2010 Complex Concrete Geometry Bridge Abutment Example Part 2 - Concrete

24. Revit Technology Conference 2010 Part 2 - Concrete Issues Not all rebar moves with the element the way we’d like it to. Adjusting 3D rebar slightly also moves the tag In a 2D elevation but the detail component doesn’t go with it. Rebar tools aren’t designed for sloped angles

25. Revit Technology Conference 2010 Apologies AS1100 could do with a revamp. for not making it this year! Have a great Conference
