How to Minimise Cutting Wastes of Reinforcement Steel Bars

The Bar Bending Schedule offers the requirements for the reinforcement steel bars that are required for the specific building structure. The Bar Bending Schedule includes different types of reinforcement bars along with different lengths and bends.

All details regarding the reinforcement steel bars need to be included in the Bar Bending Schedule in mm, which are essential in the production of the reinforcement steel bar. The specified information about the angles of the bends and the length between bends also needs to be included in the Bar Bending Schedule.

Effectiveness of Bar Bending Schedule in Construction

Accuracy of the Bar Bending Schedule

The Bar Bending Schedule helps to ensure that the reinforcement has been placed accurately in the beams or slabs.

Efficiency of the Bar Bending Schedule

The Bar Bending Schedule helps to assist the construction professionals regarding the estimation of the appropriate steel quantities, thus, the Bar Bending Schedule helps to minimise the amount of ordered rebars.

Providing guidance to the construction employees

The Bar Bending Schedule provides accurate information regarding the bend, cut or placement of the reinforcements, thus improving the entire construction procedure of the reinforcement steel bars.

Controlling design quality

The Bar Bending Schedule also helps to ensure that the building codes and engineering designs meet the quality standards.

Inventory management feature

The Bar Bending Schedule helps to maintain the steel stocks, thus preventing the excess or deficiency of the steel stocks.

Causes of the increasing waste of reinforcement steel bars

The cutting waste rates of the reinforcement steel bars can be increased by the effect of several management processes, which are as follows:

➢ While excessive purchase orders of the steel bars have been made without understanding the accurate manufacturing information, the rate of cutting waste of the reinforcement steel bars has increased. In addition, in the case of not giving proper attention to the surplus order of raw materials, there is also the chance of increasing the amount of cutting waste of the reinforcement steel bars.
➢ In the case of the excess rebars are not reused after the cutoffs, there is also the chance of an increase in the material waste rates.
➢ While the cutting planning of the reinforcement steel bars has been done without any consideration of the bending margins, the waste rates have also increased.
➢ The failure in the inventory management also leads to the enhancement of waste of reinforcement steel bars.
➢ The inappropriate management of the bending machines and cutting layouts also leads to the waste of the reinforcement steel bars.
➢ In the case of the length and location of the bar not complying with the codes, the rates of material waste of the reinforcement steel bars have also increased.

Process of minimising the cutting waste of reinforcement steel bars

The customisation in the reinforced steel bars helps to reduce the cutting waste of the reinforcement steel bars and brings significant advancement in the construction industry. This customisation can be done by following several procedures, which are as follows:

Improving project planning

The collaborative work between the contractor and steel suppliers helps to ensure that the order of the appropriate length and shapes of the reinforcement steel bars is met, as per the project requirements. This project planning helps to allocate the appropriate resources and also minimises the cutting waste of the reinforcement steel bars.

Technological advancement in the construction project

The implementation of advanced technologies helps to achieve more precise cutting and bending of the reinforcement steel bars. Thus, technological advancement in the construction of reinforcement steel bars helps to streamline the entire construction procedure and ensure the consistent quality of the reinforcement steel bars.

Implementing sustainable construction practices

The implementation of the customised steel bars also helps to minimise waste of the reinforcement steel bars and improves the resource utilisation within the construction industry.

Importance of minimising the cutting waste of reinforcement steel bars

Reduction of the costs

By minimising the material waste, the overall costs of the materials have been saved by the construction professionals. In addition, the reduction of the on-site cutting wastes also helps to minimise the overall labour cost of the construction projects, as well as improving the overall efficiency of the construction project.

Increasing sustainability

The reduction of cutting waste helps to achieve a sustainable construction project, which can align with environmental concerns.

Increasing safety

The customised bars help to reduce the cutting waste of the reinforcement steel bars, which helps to reduce the on-site manipulations and increases the overall safety of the construction projects.

Inceraisng structural integrity

To reduce the cutting waste of the reinforcement steel bars, the bars have been cut and bent more precisely, which can be fitted perfectly within the designs, thus helping to achieve a stronger and sustainable building structure.
