TCE Assistant Engineer - Civil Interview Questions, Process, and Tips for Experienced

We use grade 40 concrete for our site construction.

• Grade 40 concrete is commonly used for structural applications in construction.

• It has a compressive strength of 40 megapascals (MPa) after 28 days of curing.

• Grade 40 concrete is suitable for various construction projects such as buildings, bridges, and pavements.

Cover is provided to structures for protection against environmental factors and to increase their lifespan.

• Protects against rain, snow, wind, and sunlight

• Prevents corrosion and deterioration of materials

• Increases lifespan of the structure

• Improves aesthetics of the structure

• Examples: roofs, walls, paint coatings

Acceptance criteria for compressive strength in civil engineering

• Compressive strength is the ability of a material to withstand compressive loads

• Acceptance criteria for compressive strength is determined by the design specifications and standards

• The compressive strength of concrete is typically measured in pounds per square inch (psi)

• The acceptance criteria for compressive strength of concrete varies depending on the t

Reinforcement can be checked by visual inspection, measuring diameter, spacing, and cover, and using non-destructive testing methods.

• Visual inspection for any visible damage or corrosion

• Measuring diameter of reinforcement bars using a caliper or micrometer

• Measuring spacing between reinforcement bars using a tape measure

• Measuring cover using a cover meter

• Using non-destructive testing methods such as ultrasonic testing o

In the previous project, we used structural steel for the construction of the building.

• Structural steel was used for its high strength and durability.

• It was used in the construction of beams, columns, and other load-bearing elements.

• The specific type of steel used may vary depending on the project requirements and design specifications.

• Examples of commonly used structural steels include ASTM A36, ASTM A572, and ASTM A9
