G R Infraprojects Senior Engineer In Quality Interview Questions and Answers

PEB material refers to pre-engineered building materials used in finishing construction projects.

• PEB materials are commonly used in construction projects for their durability and cost-effectiveness.

• Examples of PEB materials include steel beams, roofing sheets, wall panels, and insulation materials.

• Quality control is essential in ensuring that PEB materials meet industry standards and specifications.

• Inspecting PEB mater...read more

The number of zones in a column depends on the specific context, such as the type of column being referred to (e.g. geographical, organizational, etc.)

• The number of zones in a column can vary based on the purpose of the column

• For example, a geographical column may have different zones representing regions or countries

• An organizational column may have zones representing departments or teams

Standard deviation is a measure of the amount of variation or dispersion of a set of values.

• Standard deviation is calculated by taking the square root of the variance.

• It is used to quantify the amount of variation or dispersion of a set of values.

• Higher standard deviation indicates more spread out data points, while lower standard deviation indicates data points are closer to the mean.

• It is commonly used in quality con...read more

To clear NCR, identify root cause, implement corrective actions, verify effectiveness, and close out the NCR.

• Identify the root cause of the non-conformance.

• Implement corrective actions to address the root cause.

• Verify the effectiveness of the corrective actions through testing or inspection.

• Close out the NCR once the corrective actions have been successful.

• Document all steps taken in the NCR clearance process.

Testing procedure for coarse aggregate involves determining its physical properties and quality through various tests.

• Conduct sieve analysis to determine particle size distribution

• Perform specific gravity and absorption test to assess porosity

• Check for shape, surface texture, and angularity through visual inspection

• Test for resistance to abrasion and impact to evaluate durability

Silt content limit as per IS code is 3% for fine aggregate.

• Silt content limit for fine aggregate as per IS code is 3%.

• Excessive silt content can affect the quality of concrete.

• Silt content can be determined by conducting a sieve analysis test.

Shear wall is a structural element used to resist lateral forces such as wind or earthquake.

• Shear walls are typically made of reinforced concrete, masonry, or wood.

• They are placed in the perimeter of a building or in the center to provide stability.

• Shear walls reduce the amount of sway or deformation in a building during a seismic event.

• They also help to distribute the load of the building evenly across the foundation.

Shear walls are used to resist lateral forces. Types include braced, unbraced, and coupled. IS code: IS 456:2000.

• Shear walls are vertical elements that resist lateral forces such as wind and earthquakes.

• Braced shear walls have diagonal braces that resist lateral forces.

• Unbraced shear walls rely on their own stiffness to resist lateral forces.

• Coupled shear walls are two or more shear walls connected by beams or slabs.

• IS...read more
