S.A. Yadav Government Contractor Site Engineer Interview Questions, Process, and Tips

The cross slope on railway formation bed refers to the slope across the width of the railway track to facilitate drainage.

• The standard cross slope on railway formation bed is typically between 1.5% to 2%.

• This slope helps in draining water away from the track to prevent waterlogging and erosion.

• Proper cross slope ensures the stability and longevity of the railway track.

• The cross slope is usually achieved by shaping the

Twist on the rail refers to the rotation of the rail along its longitudinal axis.

• Twist on the rail can occur due to various factors such as temperature changes, improper installation, or structural issues.

• It can lead to safety hazards and affect the stability and alignment of the railway track.

• Regular inspections and maintenance are necessary to detect and correct any twist on the rail.

• Example: If a rail is twisted, it...read more

The cant on the curve refers to the outward tilt or superelevation of the outer rail on a curved track to counteract the effects of centrifugal force.

• Cant is necessary to prevent trains from derailing on curves due to the outward force.

• It is typically measured in inches per foot or degrees.

• The amount of cant required depends on the speed and radius of the curve.

• For example, a high-speed curve with a tight radius will r...read more

If test piles fail in loading, investigate the cause, analyze data, and consider redesigning the foundation.

• Investigate the reason for failure, such as poor soil conditions or incorrect design calculations.

• Analyze the data collected during testing to determine the extent of the failure and potential solutions.

• Consider redesigning the foundation based on the analysis and recommendations from geotechnical engineers.

• Consu...read more

SQ1, SQ2, and SQ3 in soil refer to different soil quality levels based on specific characteristics.

• SQ1 represents the highest quality soil with excellent characteristics such as high organic matter content and good structure.

• SQ2 is moderate quality soil with some limitations like lower organic matter content or poor structure.

• SQ3 is the lowest quality soil with significant limitations such as high salinity or low ferti...read more
