Hardwin Construction Site Engineer Interview Questions and Answers

Designing beams and columns involves determining the size, material, and layout to support the required loads.

• Consider the type of structure and the loads it will bear

• Calculate the required dimensions and reinforcement based on structural analysis

• Select appropriate materials such as steel or concrete

• Ensure proper connections and detailing for stability and safety

Limit state of serviceability refers to the condition where a structure is still functioning properly without any excessive deflection or deformation.

• Limit state of serviceability ensures that a structure remains usable and safe for occupants.

• It involves checking factors like deflection, vibration, cracking, and durability.

• For example, a bridge should not deflect excessively under the weight of traffic to maintain serv...read more

CODAL provisions for concrete refer to the guidelines and regulations set by relevant authorities, while commands of software are the specific instructions or functions within a software program.

• CODAL provisions for concrete include specifications for mix design, strength requirements, and durability standards.

• Commands of software for site engineers may include functions for structural analysis, quantity takeoff, and p...read more

Cube test is a method to determine the compressive strength of concrete.

• Concrete cubes are casted and cured for 28 days before testing.

• The cubes are then placed in a compression testing machine.

• The maximum load that the cube can bear before failure is recorded.

• The compressive strength of the concrete is calculated using the formula: compressive strength = maximum load/area of cube face.

• The cube test is an important qua

ESR stands for Earth System Research, CWR stands for Crop Water Requirement, and steel IS code refers to Indian Standard code for steel.

• ESR is a research program that studies the Earth's climate system and its changes over time.

• CWR is the amount of water needed by crops to grow and produce a good yield.

• Steel IS code refers to the Indian Standard code for steel, which provides guidelines for the production and use of st

Conductors are selected based on factors like material, size, insulation, and current carrying capacity.

• Consider the material of the conductor (e.g. copper, aluminum)

• Determine the size of the conductor based on the current it will carry

• Choose the appropriate insulation for the conductor based on the environment it will be used in

• Ensure the conductor has the required current carrying capacity for the application

Initial setting time is the time taken for the cement to harden to a certain degree, while final setting time is the time taken for the cement to completely harden.

• Initial setting time is typically around 30 minutes to 1 hour after adding water to the cement.

• Final setting time is usually around 2 to 4 hours after adding water to the cement.

• Setting time can vary based on the type of cement and environmental conditions.

• S

Bleeding is the process of air escaping from fresh concrete mix and rising to the surface.

• Bleeding occurs when water in the concrete mix rises to the surface due to settlement of solid particles.

• It can lead to surface defects if not properly managed.

• Bleeding can be reduced by using proper mix design and techniques like vibration or adding admixtures.

• Excessive bleeding can weaken the surface of the concrete.

• Examples: Wa...read more
