Vegazva Engineering Interview Questions and Answers

The size of trade and rise and angle of stairs vary depending on the specific design and regulations.

• The size of trade refers to the horizontal distance between two consecutive steps.

• The rise is the vertical distance between two consecutive steps.

• The angle of stairs is determined by the ratio of rise to trade.

• Building codes and regulations provide guidelines for the minimum and maximum values for trade, rise, and angle.

• For example, a common trade size is around 11 inches, whi...read more

One bag of cement is approximately equal to 1.25 cubic feet or 0.035 cubic meters.

• One bag of cement typically contains 50 kilograms of cement.

• The volume of one bag of cement is influenced by the density of the cement.

• To convert cubic feet to cubic meters, divide the value by 35.3147.

• To convert cubic meters to cubic feet, multiply the value by 35.3147.

Pile foundations are used in conditions where the soil is weak or unstable to support the structure.

• Pile foundations are used when the soil is too weak to support the load of the structure.

• They are also used in areas with expansive soils that can cause excessive settlement.

• Pile foundations are suitable for sites with high water tables or in coastal areas where the soil is prone to erosion.

• They are commonly used in areas with soft or loose soils, such as marshy or swampy areas...read more

The weight of steel in feet can be calculated by multiplying the volume of steel by its density.

• Calculate the volume of steel by multiplying its length, width, and height

• Determine the density of the steel material being used

• Multiply the volume by the density to obtain the weight of steel in pounds

• Convert the weight from pounds to feet if necessary

The minimum thickness of a slab depends on various factors such as the load it will bear, the type of material used, and the span of the slab.

• The minimum thickness of a slab is typically determined by structural engineers based on the design requirements and local building codes.

• For residential buildings, the minimum thickness of a concrete slab is often around 4 inches (10 cm).

• For commercial or industrial buildings, the minimum thickness can vary depending on the expected lo...read more

Subgrade GSB work refers to the process of preparing the subgrade by laying Granular Sub Base material.

• Subgrade GSB work involves laying and compacting Granular Sub Base material to create a stable foundation for the road or structure.

• The thickness of GSB layer and compaction requirements are specified in the project specifications.

• Proper compaction is essential to achieve the desired strength and stability of the subgrade.

• Quality control tests such as Proctor compaction test...read more
