Grout tubes are used in the construction of precast concrete buildings for connecting elements like walls, tilt-up panels, beams, and columns. They’re also known as grout ducts or sleeves. The way it works is a starter bar (also known as a lap bar or dowel) is precast in one element, say, a wall panel, and then on site that dowel slides into a sleeve that was precast into, say, another panel. The sleeve – typically made of plastic or corrugated steel – is then filled with concrete to form a connection between the wall panels.
Since precast designs can contain quite a lot of grout tubes, placing them is certainly worth automating. That’s where the Smart Connections feature of our Precast Concrete BIM Solution for Revit comes in. It has options that you can configure so that grout tubes will be placed in walls automatically, reducing the amount of time you need to spend on repetitive, manual tasks.
Here’s the workflow that I would recommend. Steps are also laid out below the video.
We recently received a question from a client in Australia regarding how to use our Precast Concrete solution for Revit to model different types of wall joints, specifically shiplaps. The Smart Connections feature of Precast Concrete automates this process by placing Revit families according to the configurations set by the user. The families can contain any solids or voids to cut the walls and get them into the right shapes or place connection elements.
In the steps below I show how to create a shiplap joint in a bunch of precast panels all at once using Smart Connections. A similar workflow could be applied to automate the creation of different types of groove joints that are often used by precasters in wall panels too. Because we’re so focused on reducing BIM stress, we make it easier for BIM modelers to get the job done simply and quickly.
A year has passed since Tokyo-based M&F tecnica became AGACAD’s exclusive partner for sale and support of our solutions for BIM in Japan, and good things are happening in the country. Strong interest there in our Revit add-ons to automate 3D design and documentation is set to grow even more now that, with M&F’s help, they’ve been translated into Japanese!
“This partnership is yielding excellent results, strengthening AGACAD’s ability to ensure excellent service for clients in Asia and thus share BIM advances there as well,” AGACAD Managing Director Mr Donatas Aksomitas says. “M&F, who have been pioneers of BIM in Japan and Revit experts, are now experts also in AGACAD’s solutions based on the insights of top BIM professionals. Thus they are helping clients unlock even more of the immense value of modern building information modelling and management.”
AGACAD is well-known for developing tools for prefab structures, particularly wood framing, metal framing, and precast concrete. Revit-based addons help with modeling highly-detailed building models reaching LOD (Level of Detail) 400 and creating necessary documentation efficiently.
The latest feature added to our Precast Concrete design software is Column Reinforcement. Revit already has quite good tools for rebar, and the most recent versions have made it more stable than ever. But with thousands of reinforcement bars in each BIM project, it can still take a lot of time to model them, so precast engineers can benefit from other tools to work with rebar in a timely manner.
Each step is important in building design, so in this blog post we will go over the full workflow for modeling precast concrete columns and generating documentation in Revit using AGACAD’s Precast Concrete solution.
1. Modeling precast columns
Create structural columns in Revit. These are just simple standard Revit Structural Column families drawn to define the top and bottom level constraints.
Visitors to the legendary Crystal Palace, built in London for the Great Exhibition of 1851, were said to be awed by its unprecedented expanses of glass – 900,000 square feet of it (84,000 square metres). So much natural light. So spacious. Such openness to the surrounding Hyde Park, including three large elm trees left standing inside.
Want to efficiently model reinforcement for precast concrete columns in Revit? We’ve got a new tool coming out called Column Reinforcement that does exactly that. Made for rectangular columns with corbels, it’s ideal for precast designs though it can also be used for cast-in-situ.
On September 17th we’re hosting a free webinar in which we’ll showcase the automated placement of main reinforcement, stirrups, and corbel rebar via user-defined layout rules in the Column Reinforcement addin. Sign up in the table below!
The results you’ll see in this webinar are various rebar configurations applied to several types of columns with corbels as well as how to model precast columns with connection details and generate the requisite shop drawings.
The 45-minute webinar will be held twice, so please register for the session that’s more convenient for you. We invite structural engineers, modelers, and really anyone who wants to place reinforcement in Revit more efficiently. Join in and get a look at the newest feature of AGACAD’s Precast Concrete BIM design software for Revit!
During the past 2 months we’ve hosted several live webinars covering specialty framing in Revit. On the timber side, those included structural insulated panels, cross laminated timber, and post-frame (a.k.a. heavy timber, mass timber, or oak) constructions. And for metal framing, we delved into ventilated facades, glazing, and curtain walls & panels. In this post we’ve gathered those webinars into one place.
In each webinar, our BIM application engineer shows the workflow for using our wood and metal framing tools in tandem with custom Revit families and configurations to model walls, floors, and roofs; distribute connection details and hardware; generate shop drawings and cut lists; and export to CNC machines, where applicable.
Without further ado, here’s our 2020 collection of 5 webinars about specialty framing in Autodesk Revit.
Last week I posted about how to insert shoes for precast concrete columns from ProdLib libraries efficiently in Revit. Again, shout-outs to ProdLib for their great BIM content libraries and to Peikko for making their structural connections for precast concrete available for us designers to use in Revit.
This week I show how you can manually place Peikko lifting anchors and make modifications VERSUS how you can place them and change parameters automatically using our Precast Concrete BIM design software. Hope you will find this useful!
Load lifting family from ProdLib.
If the Revit family doesn’t snap to the wall face, just modify it using the Family Editor.
Let’s place manually and change some parameters.
Let’s automate the detail insertion process! Use the Smart Connections tool that’s part of our Precast Concrete BIM software.
Create a new configuration to place lifting families relative to the center of gravity.
Repeat on the side of the wall.
Apply the configuration to all walls.
Modify the configuration so that details on the wall edge will be oriented correctly…
⚡️Presto! All details are inserted based on wall shape and size. For future walls, just run the configuration to insert all those lifting anchors with JUST ONE CLICK!
Anstar and Peikko both manufacture structural connections for precast concrete. And they’ve gone the extra step of making their respective products available for designers to use by uploading them to BIM content libraries. You can find their products in the libraries put together by ProdLib. Now that’s some great BIM content right there! As we’ve been saying for years, “Manufacturers, we need you in BIM!”
Whichever manufacturer you may choose, here is a workflow for inserting column shoes efficiently from ProdLib using our Precast Concrete BIM design software for Revit.
Insert precast column shoes using Prodlib libraries.
If the Revit Family doesn’t snap to the Host, just modify it by changing a few options in the Family Editor.
Join our free 30-minute webinar on June 18th for an expert-level tutorial on how to efficiently design precast concrete structures in Revit. Hours of tedious manual tasks in the modeling, detailing, and documentation processes will be eliminated using our Precast Concrete BIM software, which handles slab layouts, wall panelization, detail distribution, rebar placement, and shop drawing prep.
The results you’ll see: Revit walls will be split into precast wall panels. Floors will be divided into slabs. Connections, grout tubes, plates, and lifting anchors will be inserted based on predefined configurations. Rebar for walls and beams will be placed. Shop drawings with proper dimensions and views will be generated in a snap. All of those tasks are automated by using our Precast Concrete Revit tool, so it saves lots of time for structural engineers, drafters, and BIM modelers.
The webinar will be held twice, so please register for the session that’s more convenient for you. We especially invite out-of-box Revit users and those thinking of switching from AutoCAD 2D to BIM to come see what’s up!
