The extra working space for 10m depth earth excavation depends on various factors such as soil type, equipment used, and safety requirements.

• The extra working space is typically calculated based on the stability of the excavation walls.

• For cohesive soils, the general rule of thumb is to provide a minimum of 1.5 times the depth of the excavation as working space.

• For non-cohesive soils, the working space required may be ...read more

The cutting length of columns ties is determined as per the IS code.

• The cutting length of column ties is calculated based on the diameter of the column and the number of longitudinal bars.

• As per the IS code, the cutting length is equal to 2 times the development length plus the lap length.

• The development length is calculated based on the grade of concrete and the diameter of the bar.

• The lap length is determined based o...read more

Minimum deduction in shuttering for main and secondary beams

• The minimum deduction in shuttering for main and secondary beams depends on the type of material used for shuttering

• For wooden shuttering, the minimum deduction should be around 20 mm

• For steel shuttering, the minimum deduction should be around 10 mm

• The deduction should be calculated based on the thickness of the shuttering material and the size of the beam

• The ...read more

Aggregates should be strong, durable, and free from impurities. Tests should include grading, shape, and texture.

• Aggregates should have high compressive strength and low water absorption.

• They should be free from organic impurities and have a low percentage of fine particles.

• Tests should include grading, shape, texture, and soundness.

• Examples of tests include the Los Angeles Abrasion Test and the Aggregate Impact Value ...read more

Rolling margins of steel as per IS code

• IS code refers to the Indian Standard code for steel

• Rolling margins are the allowable variations in dimensions during the rolling process

• These margins ensure the quality and consistency of the rolled steel

• The specific rolling margins for different types of steel are defined in the IS code

• Examples of rolling margins include thickness tolerance, width tolerance, etc.
