L&T Heavy Civil Infrastructure Civil Engineer Interview Questions and Answers

A foundation is a structural element that supports a building or other structure by transferring its load to the underlying soil or rock.

• Foundations are typically made of concrete, masonry, or steel.

• They are designed to distribute the weight of the structure evenly and prevent settlement or movement.

• Different types of foundations include shallow foundations (such as strip footings and mat foundations) and deep foundati...read more

RCC stands for Reinforced Cement Concrete.

• RCC is a composite material made of cement, sand, aggregates, and steel reinforcement.

• It is widely used in construction for its strength and durability.

• The steel reinforcement provides tensile strength to the concrete, while the cement, sand, and aggregates provide compressive strength.

• RCC is commonly used in the construction of buildings, bridges, dams, and other structures.

• Ex...read more

Leveling is the process of determining the height or elevation of a point or surface relative to a reference point.

• Leveling is commonly used in civil engineering and construction to ensure accurate measurements and proper alignment.

• It involves the use of leveling instruments such as a level, theodolite, or laser level.

• The process typically includes setting up benchmarks or reference points, taking readings at different...read more

The diameter of six mm refers to the size or measurement of a circular object that is six millimeters in width.

• The diameter is the distance across the center of a circle, passing through the circumference.

• A six mm diameter can be visualized as a circle with a width of six millimeters.

• It is a common measurement used in various industries, including engineering and manufacturing.

• For example, a six mm diameter steel rod w...read more

LEP stands for Load Equivalent Factor for Pavement design.

• LEP is used in pavement design to determine the load-carrying capacity of the pavement.

• The formula for LEP depends on the specific design method being used.

• For example, in the AASHTO design method, LEP is calculated using the formula: LEP = (ESAL/1000) * (1 + 0.003 * (T - 3))

• Here, ESAL is the Equivalent Single Axle Load and T is the pavement design period in yea...read more
