As Building Information Model (BIM) technology has expanded to include more workflows for rebar detailing adoption of these capabilities within the industry has accelerated. Owner requirements for using BIM on project has also been a factor driving adoption, particularly in markets with government BIM mandates such as the U.S. and the UK. The UK will mandate BIM Level 2 for use on all government funded projects from 2016.
Software developers are approaching this growing need in different ways. One strong solution available on the market is combining familiar, existing software with new third party add-ons. For example, SOFiSTiK, a German software development company provides a rebar detailing add-on to complement Autodesk Revit. The visual capability of Revit, coupled with the ability to design reinforced concrete in 3D, allows users to gain more insight into the design during the project than would otherwise have been the case. Customers can also leverage the Revit model to obtain cost data and to create active links with external programs through the Revit application programming interface (API) in order to add further data into the Revit model.
ABT Netherlands, a multi-disciplinary consultancy firm, focused on the structural engineering, civil engineering, architectural engineering, moved to BIM-based 3D rebar for concrete reinforced design and fabrication as a result of client demand. ABT already had in place the latest version of Autodesk® Revit® software when a UK-based client commissioned the company to handle the structural design on a project, and to produce the accompanying reinforcing bar (rebar) shop drawings. ABT used the SOFiSTiK Rebar Detailing for Revit to produce a 3D model with 2D drawing output for the rebars used on the project and then tailor it to specific needs of the UK market.

UK BAM Nuttall, part of the Dutch company Royal BAM Group, focuses on delivering quality civil engineering projects in the rail, road, maritime and energy sectors. They offer a full range of civil engineering and design services. Their use of Revit and SOFiSTiK on the Moorgate Shaft project is well documented. In this abridged video from the Autodesk Fabricators Forum, Ivor Barbrook, Head of Design Delivery and BIM Implementation for Bam Nuttall, gives a demonstration of how they used the combination of Revit and SOFiSTiK on their Moorgate Shaft project.
From these examples you can see that the BIM-centric capability of Revit, coupled with regional, material-specific third party add-ons, allowed both ABT and BAM Nuttall to produce better designs than would otherwise have been the case.
As rebar detailing within 3D Building Information Model (BIM) environment continues to grow, Autodesk and its partners will strive to make this transition easy and profitable for its customers.
