Runwal Group Junior Engineer Civil Interview Questions, Process, and Tips

Different grades of concrete are used for different structures based on their strength requirements.

• Different grades of concrete like M5, M10, M15, M20, M25, etc. are used for different structures.

• For example, M5 grade concrete is used for PCC (Plain Cement Concrete) work, while M20 grade concrete is used for RCC (Reinforced Cement Concrete) work.

• Higher grades like M30, M35, M40, etc. are used for structures requiring

D-wall stands for Diaphragm wall, a reinforced concrete wall constructed in the ground to support excavation and prevent water ingress.

• D-wall is commonly used in deep excavation projects to provide lateral support and prevent soil movement.

• It is constructed by excavating a trench, installing reinforcement bars, and pouring concrete into the trench.

• D-walls are often used in construction of underground structures like ba...read more

In high water level areas, foundation work involves dewatering techniques to lower the water table and ensure stability.

• Dewatering techniques such as wellpoint systems, deep wells, sumps, and pumping are used to lower the water table.

• Waterproofing measures like using impermeable membranes or grouting can be applied to prevent water infiltration.

• Proper drainage systems are installed to divert water away from the foundat...read more

Internal plaster thickness and ratio are important factors in construction projects.

• The standard thickness of internal plaster is usually 12mm for walls and 15mm for ceilings.

• The ratio of internal plaster is typically 1:6 (1 part cement to 6 parts sand).

• The thickness and ratio may vary depending on the specific requirements of the project and the type of surface being plastered.

Slab checking involves verifying the structural integrity and load-bearing capacity of concrete slabs.

• Check for proper reinforcement placement and spacing

• Verify concrete mix design and curing process

• Inspect for any cracks or defects

• Ensure slab thickness meets design specifications

• Perform load testing if necessary

External plaster thickness and ratio are determined based on the type of surface and desired finish.

• External plaster thickness typically ranges from 12mm to 20mm depending on the surface condition.

• The ratio of external plaster mix is usually 1:4 (cement:sand) for rough surfaces and 1:6 for smooth finishes.

• For better adhesion, a bonding agent may be added to the plaster mix.

• Proper curing is essential to ensure the stren

The density of steel is approximately 7.85 grams per cubic centimeter.

• The density of steel is a measure of how much mass is contained in a given volume of steel.

• It is commonly expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

• The density of steel can vary depending on the specific type and composition of the steel alloy.

• For example, the density of carbon steel is typically around 7.85...read more

Men are dominant in site work due to various societal and cultural factors.

• Historically, construction and site work have been male-dominated industries.

• Stereotypes and biases have led to fewer women pursuing careers in civil engineering and related fields.

• Physical demands and safety concerns associated with site work may discourage some women from entering the field.

• Lack of representation and mentorship for women in si...read more
