Accurate Rebar design and detailing for reinforcement of steel or concrete structure plays important role in raising the standards of safety for any building construction projects. The Rebar detailer prepares bar bending schedules, shop drawings and rebar dimensions for effective reinforcement. Rebar design is a time-consuming and complex process.
Improving the communication flow among different trades involved in the rebar design project helps expedite the design process and reduce the amount of reproduction. This in turn helps reduce errors and drawing time with savings in cost.
Structural design consultants generally outsource rebar design drawings work to a subcontractor or team of rebar detailers. The detailers are responsible for providing complete sheets of calculations, shop drawings and general arrangement drawings for fabrication as per the specifications. The detailer is liable to make necessary changes in the drawings till he receives final approval from consultants.
Typically for any project, reinforcement drawings may be revised many times as a result of human error or a change in design suggested by one of the trades involved in the project. This process of revising drawings play crucial role in turn around time and cost of construction. The rebar detailer can save revision time by paying off for time used by the consultant engineer in the production of final drawings. Industry best practices suggest that the detail drawings should be returned for approval and review to the consultant engineer.
Computer based Rebar detailing systems help Structural consultants, detailers and fabricators streamline approvals and co-ordinate on the same single platform. The lack of an agreed data exchange format makes it difficult for them to exchange bending schedules and other details with ease. Modern CAD systems such as AutoCAD and RebarCAD removes this limitations by allowing the user to convert project data from hand-drawn sketches to DWG, DWF or CNC files within clicks of mouse. Once information is fed to bending machine it produces reasonably accurate rebars, but the first one or two bars are taken as samples for quality check.
