An engineering skill of preparing rebar fabrication drawings or shop drawings for any reinforced concrete element for construction. Rebar placements, lapping locations, quantity, shapes with bending or cut dimensions and other specific descriptions(if any) are specified in this detail drawing.

Bar bending Schedule often known as BBS is the detailed list of bars that are required to construct any reinforced concrete element. The schedule shows the type, size, location, mark, shape, length & numbers of each bar in the detailed fabrication drawing.

A rebar detailer is a professional who has the skill to prepare rebar detail drawings and bar bending schedules. An expertise detailer applies all his knowledge to create an optimised use of rebars which results in negligible wastage of rebars.

We know that concrete is strong in compression and very weak in tension. So, the provided rebar needs to take care of that tension and other forces like lateral bending, shear, and torsion. Proper rebar detailing ensures the reinforcements are adequately placed in the required position to handle the design forces and make it a durable structural element. Improper detailing may result in the failure of the structure.
Bar bending schedule drawing includes the reinforcement placement drawings, lapping locations, bar bending shapes with its dimensions, the number of bars and any other specific details like rebar anti-corrosion coating, rebar threading, etc. By preparing a bar bending schedule drawing, we can achieve optimised use to stock length bar which reduces the rebar wastages. Hence it helps to estimate & reducing the project expenses. It also helps to pre-plan about project execution activity in stages in terms of budget, workspace, etc.

• Helps in project preplanning in terms of stage/phase-wise budget, execution period, workforce allotment etc.
• Faster execution at site, reduces construction time and reduces workforce expenses at the site.
• Using CNC improves dimensional and bending accuracy and reduces manpower expenses for bar bending.
• Dependency of skilled labours reduced due to CNC process.
• Optimized use of rebars reduces wastage.
• Improves the quality of work at site.
• Bar bending yard may be eliminated if bar cutting and bending are done in the factory.
• Better for stock monitoring and managing purposes while execution.
• Easy and fast preparation of bill of construction
