Bar Bending Schedule

What is bar bending?

The process of bending reinforcing steel into shapes necessary for reinforced concrete construction. Next comes the Bar Bending Schedule (BBS). 

What is the Bar Bending Schedule? 

The bar bending Bending is a list of rebar, a given RCC work item, and is presented in table form for easy visual reference. This table summarizes all the necessary details of the bars: diameter, bending shape, length of each bent and straight part, bending angles, total length of each bar and number of each type of bar. This information is helpful in preparing a quantity estimate.

Advantages of the bar bending Schedule (BBS):

When a bar bending Schedule  is available, the reinforcement can be cut and bent at the factory and transported to the site. This increases faster execution on site and reduces construction time and Materials cost due to the reduced need for workers to bend the bars. Bar bending also avoids wasted steel reinforcement 5 to 10% and therefore saves project costs.

Using the bar bending Schedule for when used for Fe500, save 10% more steel reinforcement compared to fe415.

On-site quality control is improved as reinforcement is provided according to the bar bending Schedule that is prepared using the provisions of the respective standard detailing codes.

Provides the best estimate of the reinforcing steel requirements for each and every structural member that can be used to calculate the overall reinforcement requirements for the entire project.

Provides better stock management for reinforcement. Steel requirements for the next phase of construction can be accurately estimated and procurement made. This avoids storing additional steel reinforcement on site for a longer time, preventing corrosion of the reinforcement in the case of coastal areas. It also avoids reinforcement shortage for work in progress by accurate estimation and thus concrete construction works can proceed smoothly.

The bar bending Schedule is very useful during the reinforcement audit and provides controls on theft and theft.

The bar bending schedule can be used to cut, bend and skeleton a structural member before it can be placed in the required position. Other activities such as excavation, PCC, etc. they can be developed in parallel with this activity. Therefore, the overall management of the project activity becomes easy and reduces the construction time. It becomes useful to prevent any damage due to excess construction time.

Provides benchmarks for quantity and quality requirements for reinforcement and concrete work.

The bar bending program provides the steel quantity requirement very precisely and thus provides an option to optimize the design in case of cost overruns.

It is easy for the site engineers to verify and approve the cut and bend length of the bar during inspection before concrete placement with the use of a bar bending Schedule  and helps better quality control.

Allows quick and easy preparation of construction invoices for clients and contractors.

The amount of reinforcement to be used is calculated using engineering formulas and standard codes, so there is no option for a rough estimate of steel reinforcement.

With the use of the bar bending Schedule , the cutting and bending of the reinforcement can be mechanized, again reducing project cost and time and reliance on skilled labor requirements. It also improves the reliability of bar bending and cutting precision.

When using mechanized bar cutting and bending, the cost of reinforced concrete work per unit is reduced and helps in optimizing construction project costs.
