Nagarjuna Construction Company Civil Site Engineer Interview Questions and Answers

Q1. Layout of columns shear wall and brick machinery work
Ans. 
Understanding the layout of columns, shear walls, and brickwork is crucial for structural integrity in civil engineering.
• Columns should be placed at regular intervals to support beams and slabs effectively.

• Shear walls are typically located in areas requiring high lateral strength, such as near stairwells or elevators.

• Brickwork should be aligned with structural elements to ensure load distribution and stability.

• Example:...read more

Q2. Use of auto level
Ans. 
An auto level is a surveying instrument used for leveling and measuring height differences accurately in construction projects.
• Used for establishing a horizontal line of sight over long distances.

• Commonly employed in grading, excavation, and foundation work.

• Example: Setting up an auto level to ensure a foundation is level before pouring concrete.

• Helps in aligning structures like walls and fences accurately.

• Can be used ...read more

Q3. Grade of concrete material
Ans. 
Concrete grade indicates its compressive strength, crucial for structural integrity in construction.
• Concrete grades are classified by their compressive strength, measured in megapascals (MPa).

• Common grades include M20 (20 MPa), M25 (25 MPa), and M30 (30 MPa), used for different structural applications.

• Higher grades like M40 and M50 are used for high-strength applications, such as bridges and high-rise buildings.

• The gra...read more

Q4. Calculation of shuttering material
Ans. 
Calculating shuttering material involves determining dimensions, types, and quantities needed for formwork in construction.
• Determine the dimensions of the structure (length, width, height).

• Calculate the area of the formwork required using the formula: Area = Length x Height.

• Consider the type of shuttering material (plywood, steel, etc.) based on project requirements.

• Account for waste and overlaps; typically add 10-15% ...read more

Q5. Billing of use work of building structure
Ans. 
Billing for building structures involves quantifying work done and pricing it accurately for project management.
• Understand the scope of work: Clearly define what work is included in the billing.

• Measurement: Use standard measurement techniques (e.g., cubic meters for concrete) to quantify work.

• Rate analysis: Determine the cost per unit for materials, labor, and overhead.

• Bill of Quantities (BoQ): Prepare a detailed BoQ l...read more

Q3. What is the minimum thickness of grade slab
Ans. 
The minimum thickness of grade slab depends on the load it will bear and the soil conditions.
• The thickness of the grade slab should be determined by a structural engineer.

• It should be thick enough to support the weight of the structure and any additional loads.

• The soil conditions should also be taken into consideration when determining the thickness.

• For example, if the soil is soft or unstable, a thicker slab may be re...read more
