Gi Group Civil Site Engineer Project Engineer Interview Questions and Answers

Bracing rods are structural components used to provide stability and support in construction and engineering projects.

• Bracing rods are typically made of steel or other strong materials.

• They are used to resist lateral forces and prevent structural deformation.

• Commonly found in bridges, towers, and buildings to enhance stability.

• Example: Diagonal bracing in a steel frame building helps distribute loads.

Purlins are horizontal beams in a roof structure that support the roof covering and are essential for stability.

• Purlins are typically made of steel, wood, or aluminum.

• They are placed perpendicular to the rafters or trusses.

• Purlins help distribute the load of the roof covering evenly.

• Commonly used in commercial and industrial buildings.

• Examples include Z-purlins and C-purlins, named for their shapes.

A sagging rod is a structural element that experiences downward deflection due to loads, typically used in construction.

• Sagging rods are often used in beams and trusses to support loads.

• The length of a sagging rod depends on the span it covers and the load it bears.

• For example, a sagging rod in a bridge may span several meters, while one in a small structure may be only a few feet.

• Sagging can indicate structural issues...read more

500D means the yield strength of TMT bars is 500 MPa.

• 500D is a grade of TMT bars used in construction.

• The 'D' stands for ductility, which is the ability of the material to deform without breaking.

• The yield strength of 500D TMT bars is 500 MPa.

• These bars are commonly used in high-rise buildings, bridges, and other structures that require high strength and durability.

The stress failure at brick wall can be due to compressive or tensile stress.

• Compressive stress failure occurs when the brick wall is unable to withstand the weight or load placed on it.

• Tensile stress failure occurs when the brick wall is unable to withstand the forces that pull it apart.

• Cracking, bulging, or collapse of the wall can be signs of stress failure.

• Reinforcing the wall with steel bars or using thicker brick...read more

White marble is a metamorphic rock composed of recrystallized carbonate minerals, mainly calcite or dolomite.

• It is commonly used in construction and sculpture.

• It is formed from limestone or dolomite that has undergone heat and pressure.

• It is often found in quarries in countries such as Italy, Greece, and India.

Standard coarse sand size ranges from 2.0mm to 4.75mm.

• Standard coarse sand is commonly used in construction and civil engineering projects.

• It is typically graded between 2.0mm to 4.75mm in size.

• This type of sand is often used as a base material for concrete and asphalt.

• It can also be used for drainage systems and as a bedding material for pipes.

• The size and shape of the sand particles can affect the strength and durabi...read more

To estimate aggregate quantity for a 200sqmt slab, calculate the volume of concrete required and then determine the aggregate quantity based on the mix ratio.

• Calculate the volume of concrete required for the slab

• Determine the mix ratio of concrete (e.g., 1:2:4)

• Calculate the volume of aggregates needed based on the mix ratio

• Consider the bulk density of aggregates to convert volume to weight

• Account for wastage and add a ...read more

Before casting, civil engineers need to check the quality of various elements.

• Quality of concrete mix

• Quality of reinforcement bars

• Quality of formwork

• Quality of water used in the mix

• Quality of curing process

Post concrete quality inspection involves evaluating the quality of concrete after it has been placed and hardened.

• Inspect the concrete for any visible defects such as cracks, honeycombing, or segregation.

• Check the concrete strength by conducting compressive strength tests on samples taken from the structure.

• Assess the concrete's durability by examining its resistance to factors like freeze-thaw cycles or chemical expo...read more
