HCLTech Interview Questions and Answers

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 greater, often around 2 times the depth of the excavation....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 deduction is necessary to ensure that the shuttering can b...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 Test.

Precautions for deep excavation include shoring, sloping, benching, and proper soil analysis.

• Ensure proper shoring is in place to prevent collapse

• Slope the excavation walls to prevent soil movement

• Bench the excavation to provide stability

• Conduct soil analysis to determine the appropriate precautions

• Provide adequate lighting and ventilation

• Ensure proper training and supervision of workers

• Have an emergency response plan in place

Analysis and material calculations for brick work and plaster design mix.

• Analyze the dimensions and requirements of the brick work and plaster design

• Calculate the required amount of materials for the design mix

• Consider factors such as strength, durability, and cost when selecting materials

• Ensure compliance with building codes and regulations

• Collaborate with architects, engineers, and contractors to ensure successful project completion

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 on the grade of concrete and the diameter of the bar.

• For ex...read more
