Civil Site Execution Engineer Interview Questions and Answers

Interview questions for Civil Site Execution Engineer covering topics such as point of contrafrection, soil bearing capacity, types of beams/columns/slabs, PT slab, earthquake zones, parapet height requirements, slum ratio, aggregate quality check, etc.

• Point of contrafrection is the point where the bending moment is zero in a beam

• Soil bearing capacity is the maximum load that can be applied to the soil without causing failure

• Types of beams include simply supported, cantilever...read more

Shear force is maximum at supports and Bending moment is maximum at mid-span.

• Shear force is maximum at the supports where the load is applied.

• Bending moment is maximum at mid-span where the beam is most likely to bend.

• The location of maximum shear force and bending moment depends on the type of loading and support conditions.

• For example, in a simply supported beam with a uniformly distributed load, the maximum bending moment occurs at mid-span and the maximum shear force occu...read more

Concrete is a composite material made of cement, water, aggregates, and sometimes admixtures, used in construction.

• Concrete is a versatile material used in construction for its strength and durability.

• The design mix of concrete refers to the proportions of cement, water, aggregates, and admixtures used to achieve the desired strength and workability.

• For example, a common design mix for concrete is 1:2:4, which means 1 part cement, 2 parts sand, and 4 parts gravel.

• The design m...read more

The grade of M20 concrete refers to the mix ratio of cement, sand, and aggregate used in the concrete mix.

• M20 concrete has a mix ratio of 1:1.5:3 (1 part cement, 1.5 parts sand, 3 parts aggregate)

• The compressive strength of M20 concrete is 20 MPa (Megapascals) after 28 days of curing

• M20 concrete is commonly used for residential construction like foundations, slabs, and columns

Minimum 12 mm column is used in structures for providing adequate strength and stability.

• Minimum 12 mm column is used to ensure structural integrity and load-bearing capacity.

• Thicker columns are typically used in high-rise buildings or structures with heavy loads.

• Reinforcement bars of 12 mm diameter or larger are commonly used in column construction.

Steel weight refers to the mass of steel used in a structure or component.

• Steel weight is typically measured in kilograms or pounds.

• The weight of steel can vary depending on the type of steel used and the dimensions of the structure.

• Calculating steel weight involves multiplying the volume of steel by its density.

• Steel weight is an important factor in structural engineering to ensure the stability and safety of a building or infrastructure.

• For example, a steel beam used in con...read more
