Rohan Builders Senior Engineer QS Interview Questions and Answers

The grade of concrete refers to its strength and is determined by the ratio of cement to sand to aggregate.

• The grade of concrete is typically denoted by a number followed by the letter 'M', such as M20, M30, etc.

• The number in the grade represents the compressive strength of the concrete in megapascals (MPa) after 28 days of curing.

• For example, M20 concrete has a compressive strength of 20 MPa, while M30 concrete has a ...read more

The unit used for estimating painting work is square feet.

• Square feet is commonly used to estimate the amount of paint needed for a project.

• Other units like square meters can also be used depending on the region.

• Calculations are based on the surface area to be painted.

RL in survey stands for Reduced Level, which is the vertical distance between a point and a reference point.

• RL is used in surveying to determine the elevation of a point relative to a known reference point.

• It is commonly used in construction projects to ensure accurate leveling of structures and surfaces.

• RL can be calculated using leveling instruments such as a dumpy level or a theodolite.

• For example, if a benchmark ha...read more

Types of cement include Portland cement, rapid-hardening cement, and sulfate-resistant cement.

• Portland cement is the most common type and is used in general construction.

• Rapid-hardening cement sets quickly and is often used in repair work.

• Sulfate-resistant cement is used in areas where soil or water has high sulfate content.

The size of columns in civil engineering is determined based on the load they will support and the height of the structure.

• Columns are sized based on the load they will support, with larger loads requiring larger columns.

• The height of the structure also plays a role in determining column size, with taller structures requiring larger columns for stability.

• Factors such as material strength, column spacing, and building c...read more

Mivan slab cycle is a construction technique using aluminum formwork for casting slabs in a repetitive cycle.

• Mivan slab cycle involves setting up aluminum formwork panels for casting slabs.

• The cycle includes fixing reinforcement, pouring concrete, curing, and then dismantling the formwork for reuse.

• This method is efficient, cost-effective, and results in high-quality finishes.

• Mivan slab cycle reduces construction time ...read more

Before concreting, ensure proper formwork, reinforcement placement, concrete mix design, and weather conditions.

• Check formwork for proper alignment and stability

• Ensure reinforcement bars are correctly placed as per design

• Verify concrete mix design meets project specifications

• Monitor weather conditions to prevent issues like rain or extreme temperatures affecting the concrete

Under and over reinforcement in beams and columns refers to the amount of reinforcement provided in relation to the required strength of the structure.

• Under reinforcement occurs when the amount of reinforcement provided is less than what is required for the structure to carry the design loads.

• Over reinforcement occurs when the amount of reinforcement provided is more than what is required for the structure, leading to ...read more

NDT tests of members are done to ensure structural integrity and safety.

• NDT tests are non-destructive tests used to evaluate the properties of a material, component, or system without causing damage.

• These tests help in detecting defects such as cracks, voids, and discontinuities that may compromise the structural integrity of the members.

• By conducting NDT tests, engineers can ensure the safety and reliability of struct...read more
