Today, structural engineering firms who work on mega construction projects are using BIM tools for modeling concrete reinforcement to cut down field errors and reduce waste on-site. But that’s just one side of the coin. Those structural firms working on small scale projects are still hesitant to model, and they prefer manual framework. And if you have ever used BIM, you will not deny that the concrete BIM productivity is quite low compared to other aspects like steel or wood.
So what is it that you would want, or expect of your BIM reinforced model? Well the answers lies in how you want the tool to meet your requirements. Or what can make the model really efficient. To know that let’s say what cannot. Maybe the following thoughts can help.
From what I have observed, there are two key factors that work behind ‘WHY’ engineers or rebar detailers hesitate to develop 3D rebar models is that Software used is too tough to operate and the complex layout is barely supported. Mind you, these are not the only reasons.
Poor performance of 3D rebar model too is what keeps them away. The leading software should enhance user experience by giving them the space of creating 3D models of any given rebar configuration, without constraining the productivity. With fast moving projects and tight deadlines BIM tools are likely to manage hundreds or thousands of bars, all in 3 Dimension with suitable performance and visualization competences.
What should you expect from your BIM model?
- It should be more user friendly in terms of details, elevation and plans; when performing drawing production
- Modifications made to 3D model should reflect in drawings with absolutely no intrusions.
- The customized bar bending schedules and the Quantity reports should be bang on.
- Rebar must be given mutual bar marks by means of typical marking schemes picked by the handler.
- Alike bars would get automatically gathered to lessen the amount of exclusive bars and to reduce fabrication and building costs.
- It should enable users to simply modify the layout of everything, quantity reports, material lists bar bending agendas and much more.
Taking into consideration the number of unique pieces that are required to install, the count of rebar on a jobsite would be more than any other component used. Fastening systems such as screws and nails are an exception. Stable and dependable BIM software that can be utilized for reinforced concrete projects is now the dire necessity. However; the good news is that building construction stakeholders including designers, engineers, fabricators and even detailers now have more options to choose from software applications that are maturing with time.
