BD Buildcon Billing Engineer Interview Questions, Process, and Tips

Rolling margin of TMT bars refers to the difference between the theoretical weight and the actual weight of the bars after rolling.

• Rolling margin is calculated by subtracting the actual weight of the TMT bar from the theoretical weight.

• It is important to control the rolling margin to ensure the quality and consistency of the TMT bars.

• For example, if the theoretical weight of a TMT bar is 10 kg and the actual weight aft...read more

Plastering work is typically measured in square meters or square feet.

• Plastering work is usually measured in terms of area covered, such as square meters or square feet.

• The thickness of the plaster is also taken into account when measuring the work.

• For example, if a wall is plastered with a thickness of 15mm, the measurement would be different compared to a wall plastered with 20mm thickness.

Wastage of TMT and concrete can occur due to improper handling, inaccurate measurements, and lack of proper planning.

• Improper handling of materials during transportation and storage can lead to wastage.

• Inaccurate measurements during cutting and bending of TMT bars can result in wastage.

• Lack of proper planning and coordination among the construction team can also contribute to wastage.

• Using excess concrete than required...read more
