How to add starter rebar for precast wall panels in Revit [VIDEO]

One of the great things about hearing from clients around the world in the AEC industry is learning different ways of designing. In New Zealand and some other countries, for example, precast designers have to account for what is called starter rebar, that is, a length of bar at the bottom of the wall panels that is bent into cast in situ concrete.

Revit users can model this one by one using native Revit commands, but that would take quite a long time. With our Wall Reinforcement add-in, starter bars can be generated for all selected walls at once along with all the other necessary rebar. And that frees up structural engineers and detailers to focus on bigger fish to fry.

Follow the three steps below to model starter rebar in your precast Revit project using Wall Reinforcement.

1. Use Additional Reinforcement tab in Wall Reinforcement Configurations window

There are lots of settings for configuring reinforcement, but for starter bars use this one:

Define parameters based on L-shape rebar image. Note that if you use Interior Cover to define rebar position, it will be bent to the exterior side of the wall and vice versa.

2. Link configuration to selected Wall Type

Select your wall and use the Wall Link command. In the dialog, Wall Type is already selected, so just pick the rebar configuration you want to use.

3. Create rebar for selected walls

You can see starter bars were created across the bottom of my wall panels here. Other reinforcement is seen as well because I had more settings made in my configuration to do that.

So that’s how to create starter bars for precast walls using our Wall Reinforcement Revit add-on. Here’s a video showing how to do it as well.

Wall Reinforcement is offered as a standalone Revit add-in, but it is also available as an included feature of our Precast Concrete design software, which helps structural engineering teams model elements, place details like rebar and connections, and generate piece drawings much faster than just using plain Revit.

If you’d like to try out Wall Reinforcement, take a free 14-day trial of it. Start by downloading our TOOLS4BIM Dock. You can take a trial of the whole Precast Concrete package or just Wall Reinforcement if you prefer.

Would you like a free demo to go along with that trial?

Yes? Then…

*Pro Tip: It’s best to have the demo before testing out the tool for yourself. That way you’ll enter your free trial period with a better idea of how to use the tool.
